How to preview a Source Assistant SQL Command with parameters - ssis

TL;DR: A data flow task "works" when the package runs, but I am unable to view the query when clicking "preview" in the Data flow Source Assistant.
My working theory is that somehow the Source Assistant is unable to get the value of the parameter when previewing. I tried to resolve this problem by use of (iterations) "Parameter" and "Variable" without success. The example shown below use "Parameter".
In an SSIS Data Flow task, I have a Source Assistant with "SQL Command" as its data access mode.
SELECT h.Campus,
h.StudentName,
h.StudentId,
h.EntryDate
FROM dbo.RwsBaseEnrollmentHistory h
WHERE h.Campus = ?;
The question mark indicates a parameter, which I have defined in "Parameters".
In the OLE DB Source Editor, I made sure to map the variable to the parameter.
When I click "Preview" I get an error:
The data in question cannot be shared, but trust me when I say that when I run the package, the query works as intended. It's the inability to preview the query that I'd like to be able to fix.
What do I need to do so that I can preview the query without having to hard-code the parameter value?

I stumbled into a possible answer. It appears to work so far and I haven't been able to break it. If there is a better way of doing this I would love feedback.
This is my resolution:
Create a variable to hold the desired query (like shown in the example above). In this example, I name it EnrollmentHistory.
In the "Expression", click the [...] button and paste the query. Be sure that double-quotes surround the query.
"SELECT
h.Campus,
h.StudentName,
h.StudentId,
h.EntryDate
FROM dbo.RwsBaseEnrollmentHistory h
WHERE h.Campus = '" + # [User::Campus] + "'"
Press the "Evaluate Expression" button and press OK.
Go back to your Source Assistant and select "SQL Command from Variable" as the Data Access Mode and the Variable you just defined (in this case EnrollmentHistory) as the Variable name. You will see that the parameter is correctly resolved in the Variable Value.

SSIS - Loop Through Active Directory

Disclaimer: new to SSIS and Active Directory
I have a need to extract all users within a particular Active Directory (AD) domain and import them into Excel. I have followed this: https://www.itnota.com/query-ldap-in-visual-studio-ssis/ in order to create my SSIS package. My SQL is:
LDAP://DC=JOHN,DC=JANE,DC=DOE;(&(objectCategory=person)(objectClass=user)(name=a*));Name,sAMAccountName
As you know there is a 1,000 row limit when pulling from the AD. In my SQL I currently have (name=a*) to test the process and it works. I need to know how to setup a loop with variables to pull all records and import into Excel (or whatever you experts recommend). Also, how do I know what the other field names are that are available to pull?
Thanks in advance.
How do I see what's in Active Directory
Tool recommendations are off topic for the site but a tool that you can download, no install required, is AD Explorer It's a MS tool that allows you to view your domain. Highly recommend people that need to see what's in AD use something like this as it shows you your basic structure.
What's my domain controller?
Start -> Command Prompt
Type set | find /i "userdnsdomain" and look for USERDNSDOMAIN and put that value in the connect dialog and I save it because I don't want to enter this every time.
Search/Find and then look yourself up. Here I'm going to find my account by using my sAMAccountName
The search results show only one user but there could have been multiples since I did a contains relationship.
Double clicking the value in the bottom results section causes the under pane window to update with the details of the search result.
This is nice because while the right side shows all the properties associated to my account, it's also updated the left pane to navigate to the CN. In my case it's CN=Users but again, it could be something else in your specific environment.
You might discover an interesting categorization for your particular domain. At a very large client, I discovered that my target users were all under a CN
(Canonical Name, I think) so I could use that in my AD query.
There are things you'll see here that you sure would like to bring into a data flow but you won't be able to. Like the memberOf that's a complex type and there's no equivalent in the data flow data types for it. I think Integer8 is also something that didn't work.
Loop the loop
The "trick" here is that we'll need to take advantage of the
The name of the AD provider has changed since I last looked at this. In VS 2017, I see the OLE DB Provider name as "OLE DB Provider for Microsoft Directory Service"
Put in your query and you should get results back. Let that happen so the metadata is set.
An ADO.NET source does not support parameterization as the OLE DB does. However, you can apply an Expression on the Data Flow which surfaces the component and that's what we'll do.
Click out of the Data Flow and back into the Control Flow and right click on the Data Flow and select Properties. In that properties window, find Expressions and click the ellipses ... Up pops the Property Expressions Editor
Find the ADO.NET source under Property and in the Expressions section, click the Ellipses.
Here, we'll use your same source query just to prove we're doing the right things
"LDAP://DC=JOHN,DC=JANE,DC=DOE;(&(objectCategory=person)(objectClass=user)(name=" + "a" + "*));Name,sAMAccountName"
We're doing string building here so the problem we're left to solve is how we can substitute something for the "a" in the above query.
The laziest route would be to
Create an SSIS variable of type String called CurrentLetter and initialize it to a
Update the expression we just created to be "LDAP://DC=JOHN,DC=JANE,DC=DOE;(&(objectCategory=person)(objectClass=user)(name=" + #[USer::CurrentLetter] + "*));Name,sAMAccountName"
Add a Foreach Loop Container (FELC) to your Control Flow.
Configure the FELC with an enumerator of "Foreach Item Enumerator"
Click the Columns...
Click Add (this results in Column 0 with data type String) so click OK
Fill the collection with each letter of the alphabet
In the Variable Mappings tab, assign Variable User::CurrentLetter to Index 0
Click OK

Export stored procedure result set to Excel in SSMS

i'm using SSMS and attempting to export the results of a stored procedure to a new excel file. The SP accepts an int parameter but I cannot find a way to call it in the query.
Latest effort-
EXEC sp_makewebtask
#outputfile = 'C:\Users\me\Documents\testing.xls',
#query = **ExportAsExcel** N'#id' = 123
#colheaders =1,
#FixedFont=0,#lastupdated=0,#resultstitle='Testing details'
Running the stored procedure results in two tables of data, which I need on separate sheets. Can any of you advise a better way to go about this? It doesn't even need to be automated, I just need to get the correct data. The sp name is bolded above.
Thanks for your time,
H
I suggest you split your stored procedure into two procedures that each respectively return a separate table and have those called to different worksheets.
There are a variety of ways to return data to Excel using SQL
Here is a favourite of mine from code by Joshua (you don't have to use the parameters):
Select the Data tab on Excel's Ribbon, then within the Get Exernal Data group choose the "From other Sources" drop-down. Then Choose "From Microsoft Query"
Within "Choose Data Source" pop-up box, select your SQL Server, then hit OK.
Close the "Add Tables" popup if necessary.
Click on the "SQL" button, or choose View > SQL to open the SQL pop-up editor.
Enter the following syntax: {CALL myDatabaseName.dbo.myStoredProc (?, ?, ?)}
For example: {CALL northwind.dbo.spGetMaxCost (?, ?, ?)}
Be sure to include the squiggly braces around the call statement. Each Question Mark (?) indicates a parameter. If your stored procedure calls for more or less parameters, add or subtract question marks as needed.
Hit the OK button. A question box should pop-up saying "SQL Query can't be represented graphically, continue anyway?", just hit the OK button.
You will now be asked for sample parameters for each question mark you included above. Enter valid parameter values for the data you are querying.
Once you have entered the last parameter, you should get some results back in Microsoft Query. If they look good, close Microsoft Query.
You should now be looking at an "Import Data" pop-up. Click the Properties button, which will bring up the "Connection Properties" pop-up.
Select the Definition tab, then select the Parameters button. You should now see a "Parameters" pop-up, where you can connect the parameter to a specific cell.
Select Get the value from the following cell, and then connect to an appropriate cell in Excel that will hold your parameter, by clicking the little box with the arrow.
If you want the data to refresh every time you change the cell containing the parameter, check the box stating "Refresh automatically when cell value changes"
Continue as above for the other parameters. When finished, click OK, to return to the Connection Properties pop-up. Click OK to return to the Import Data pop-up, and click OK again.
You should now have some data straight from your stored procedure.
You will end up with connection information similar to:
Connection info
And, if you use parameters from sheet then, for my example,
This isn't a direct answer to your question, but it is possible using Excel VBA and connections to connect to a SQL Server Stored Procedure, feed it parameters, and return the SP result set in Excel. Check out my article Microsoft Excel & SQL Server: Self service BI to give users the data they want for an image and code-heavy demo.
Good luck.
There's too much detail there to post in a single SO question, otherwise I'd do that here.
I develop SSMSBoost add-in and we have implemented the functionality, that allows you to export data to excel in 3 ways (including creation of several worksheets in one file):
You can export all result grids in one operation to "open worksheet" file format, which excel understands and displays correctly. This file format supports multiple worksheets.
to use it: right-click the data grid in SSMS and select "Script grid data"-> "Excel" template->All Grids->ToDisk.
You can also look inside the generated files to understand how it works. You can then implement same functionality in your stored procedure if you want to stay independent of add-ins. Sample XML is also provided below. (2 excel sheets with 1 column name and 1 value)
<?xml version="1.0"?>
<?mso-application progid="Excel.Sheet"?>
<Workbook xmlns="urn:schemas-microsoft-com:office:spreadsheet"
xmlns:o="urn:schemas-microsoft-com:office:office"
xmlns:x="urn:schemas-microsoft-com:office:excel"
xmlns:ss="urn:schemas-microsoft-com:office:spreadsheet"
xmlns:html="http://www.w3.org/TR/REC-html40">
<ExcelWorkbook xmlns="urn:schemas-microsoft-com:office:excel">
</ExcelWorkbook>
<Styles>
<Style ss:ID="sH1"><Font ss:Bold="1"/></Style>
<Style ss:ID="sD1"><NumberFormat ss:Format="General Date"/></Style>
<Style ss:ID="sD2"><NumberFormat ss:Format="Short Date"/></Style>
<Style ss:ID="sD3"><NumberFormat ss:Format="Short Time"/></Style>
</Styles>
<Worksheet ss:Name="GridResults1">
<Table>
<Row>
<Cell ss:StyleID="sH1"><Data ss:Type="String">ColumnNameA</Data></Cell>
</Row>
<Row>
<Cell><Data ss:Type="Number">1</Data></Cell>
</Row>
</Table>
</Worksheet>
<Worksheet ss:Name="GridResults2">
<Table>
<Row>
<Cell ss:StyleID="sH1"><Data ss:Type="String">ColumnNameB</Data></Cell>
</Row>
<Row>
<Cell><Data ss:Type="Number">1</Data></Cell>
</Row>
</Table>
</Worksheet>
</Workbook>
You can also copy-paste data from SSMS Grid, right-clicking it and choosing "Copy selection as XML Spreadsheet (Excel)". Data will be copied preserving data types.
More advanced option is our "Post execution handlers" functionality. It allows you to run certain actions after query execution completes. You can schedule automatic export to excel file here as well.
Hope this helps, with, or without SSMSBoost ;)

How does one view the SQL query that a button fires in Access?

There is an existing Access program that I need to learn more about. There is a button in the program that, when pressed, outputs an Excel file. It queries some tables within it for the data.
How would I view the raw SQL code that this button utilizes to generate this Excel file? From the button's properties, I can see that its On Click event is "[Embedded Macro]". Also, it's object type is "Query".
Thank you in advance.
In the On Click row (under the Event tab in Properties), when I click on the ellipse next to "[Embedded Macro]", I am presented with an expandable section containing these rows:
Object Type - Query
Object Name - Inv File Query
Output Format - Excel Workbook (*.xlsx)
Output File - (blank)
Auto Start - No
Template File - (blank)
Encoding - (blank)
Output Quality - Print
I don't see any logic (SQL, VBA, etc.) listed anywhere, however, as to how Access will construct this Excel file that it exports. How would I view this logic? I figure this logic has to be stored somewhere because the button does actually return an Excel file populated with data.
You have the name of the query used here.
The SQL thus used is in a query called Inv File Query.
So you need to display the query objects in the nav pane (assuming 2007 onwards).
So choose this:
And then all of the queries used in the application will display. If the query Inv File Query does not show, it may be hidden. (to be fair, I would choose All Access objects - but for this we choose query). And hit F11 if the nav pane does not show.
If for some reason you STILL do not see the query, then you want to display hidden objects.
To display all hidden objects then right click on the top part of the nav pane (on the query) like this:
Then:
Turn all of the options, and now you should be able to see/view the SQL used for the query called Inv File Query
Open the form in Design view
Open the Properties sheet by right-clicking on the button and choosing "Properties".
In the On Click event, where you see "[Embedded Macro]", click on the ellipse on the far right
As a pointer, once you've figured out what's going on, I'd do my best to convert it all to VBA code. This will eliminate confusion in the future, and macros are really the poor man's way out of writing code anyway. I never, ever use macros in my Access apps.

ssis 2005, write on excel files [duplicate]

I am working with SSIS 2008. I have a select query name sqlquery1 that returns some rows:
aq
dr
tb
This query is not implemented on the SSIS at the moment.
I am calling a stored procedure from an OLE DB Source within a Data Flow Task. I would like to pass the data obtained from the query to the stored procedure parameter.
Example:
I would like to call the stored procedure by passing the first value aq
storedProdecure1 'aq'
then pass the second value dr
storedProdecure1 'dr'
I guess it would be something like a cycle. I need this because the data generated by the OLE DB Source through the stored procedure needs to be sent to another destination and this must be done for each record of the sqlquery1.
I would like to know how to call the query sqlquery1 and pass its output to call another stored procedure.
How do I need to do this in SSIS?
Conceptually, what your solution will look like is an execute your source query to generate your result set. Store that into a variable and then you'll need to do iterate through those results and for each row, you'll want to call your stored procedure with that row's value and send the results into a new Excel file.
I'd envision your package looking something like this
An Execute SQL Task, named "SQL Load Recordset", attached to a Foreach Loop Container, named "FELC Shred Recordset". Nested inside there I have a File System Task, named "FST Copy Template" which is a precedence for a Data Flow Task, named "DFT Generate Output".
Set up
As you're a beginner, I'm going to try and explain in detail. To save yourself some hassle, grab a copy of BIDSHelper. It's a free, open source tool that improves the design experience in BIDS/SSDT.
Variables
Click on the background of your Control Flow. With nothing selected, right-click and select Variables. In the new window that pops up, click the button that creates a New Variable 4 times. The reason for clicking on nothing is that until SQL Server 2012, the default behaviour of variable creation is to create them at the scope of the current object. This has resulted in many lost hairs for new and experienced developers alike. Variable names are case sensitive so be aware of that as well.
Rename Variable to RecordSet. Change the Data type from Int32 to Object
Rename Variable1 to ParameterValue. Change the data type from Int32 to String
Rename Variable2 to TemplateFile. Change the data type from Int32 to String. Set the value to the path of your output Excel File. I used C:\ssisdata\ShredRecordset.xlsx
Rename Variable 4 to OutputFileName. Change the data type from Int32 to String. Here we're going to do something slightly advanced. Click on the variable and hit F4 to bring up the Properties window. Change the value of EvaluateAsExpression to True. In Expression, set it to "C:\\ssisdata\\ShredRecordset." + #[User::ParameterValue] + ".xlsx" (or whatever your file and path are). What this does, is configures a variable to change as the value of ParameterValue changes. This helps ensure we get a unique file name. You're welcome to change naming convention as needed. Note that you need to escape the \ any time you are in an expression.
Connection Managers
I have made the assumption you are using an OLE DB connection manager. Mine is named FOO. If you are using ADO.NET the concepts will be similar but there will be nuances pertaining to parameters and such.
You will also need a second Connection Manager to handle Excel. If SSIS is temperamental about data types, Excel is flat out psychotic-stab-you-in-the-back-with-a-fork-while-you're-sleeping about data types. We're going to wait and let the data flow actually create this Connection Manager to ensure our types are good.
Source Query to Result Set
The SQL Load Recordset is an instance of the Execute SQL Task. Here I have a simple query to mimic your source.
SELECT 'aq' AS parameterValue
UNION ALL SELECT 'dr'
UNION ALL SELECT 'tb'
What's important to note on the General tab is that I have switched my ResultSet from None to Full result set. Doing this makes the Result Set tab go from being greyed out to usable.
You can observe that I have assigned the Variable Name to the variable we created above (User::RecordSet) and I the Result Name is 0. That is important as the default value, NewResultName doesn't work.
FELC Shred Recordset
Grab a Foreach Loop Container and we will use that to "shred" the results that were generated in the preceding step.
Configure the enumerator as a Foreach ADO Enumerator Use User::RecordSet as your ADO object source variable. Select rows in the first table as your Enumeration mode
On the Variable Mappings tab, you will need to select your variable User::ParameterValue and assign it the Index of 0. This will result in the zerotth element in your recordset object being assigned to the variable ParameterValue. It is important that you have data type agreement as SSIS won't do implicit conversions here.
FST Copy Template
This a File System Task. We are going to copy our template Excel File so that we have a well named output file (has the parameter name in it). Configure it as
IsDestinationPathVariable: True
DestinationVarible: User::OutputFileName
OverwriteDestination: True
Operation: Copy File
IsSourcePathVariable: True
SourceVariable: User::TemplateFile
DFT Generate Output
This is a Data Flow Task. I'm assuming you're just dumping results straight to a file so we'll just need an OLE DB Source and an Excel Destination
OLEDB dbo_storedProcedure1
This is where your data is pulled from your source system with the parameter we shredded in the Control Flow. I am going to write my query in here and use the ? to indicate it has a parameter.
Change your Data access mode to "SQL Command" and in the SQL command text that is available, put your query
EXECUTE dbo.storedProcedure1 ?
I click the Parameters... button and fill it out as shown
Parameters: #parameterValue
Variables: User::ParameterValue
Param direction: Input
Connect an Excel Destination to the OLE DB Source. Double click and in the Excel Connection Manager section, click New... Determine if you're needing 2003 or 2007 format (.xls vs .xlsx) and whether you want your file to have header rows. For you File Path, put in the same value you used for your #User::TemplatePath variable and click OK.
We now need to populate the name of the Excel Sheet. Click that New... button and it may bark that there is not sufficient information about mapping data types. Don't worry, that's semi-standard. It will then pop up a table definition something like
CREATE TABLE `Excel Destination` (
`name` NVARCHAR(35),
`number` INT,
`type` NVARCHAR(3),
`low` INT,
`high` INT,
`status` INT
)
The "table" name is going to be the worksheet name, or precisely, the named data set in the worksheet. I made mine Sheet1 and clicked OK. Now that the sheet exists, select it in the drop down. I went with the Sheet1$ as the target sheet name. Not sure if it makes a difference.
Click the Mappings tab and things should auto-map just fine so click OK.
Finally
At this point, if we ran the package it would overwrite the template file every time. The secret is we need to tell that Excel Connection Manager we just made that it needs to not have a hard coded name.
Click once on the Excel Connection Manager in the Connection Managers tab. In the Properties window, find the Expressions section and click the ellipses ... Here we will configure the Property ExcelFilePath and the Expression we will use is
#[User::OutputFileName]
If your icons and such look different, that's to be expected. This was documented using SSIS 2012. Your work flow will be the same in 2005 and 2008/2008R2 just the skin is different.
If you run this package and it doesn't even start and there is an error about the ACE 12 or Jet 4.0 something not available, then you are on a 64bit machine and need to tell BIDS/SSDT that you want to run in 32 bit mode.
Ensure the Run64BitRuntime value is False. This project setting can be found by right clicking on the project, expand the Configuration Properties and it will be an option under Debugging.

SSIS Use DataFlow task with variables instead of a source database

I have a task that I am working on that has me stumped. Hoping you can help me. I am using a data flow task which is basically inserting a row into a sqlite table. I was doing this using a "SQL Task" but unfortunately the only way to successfully insert a guid into the sqlite table is to convert it as a byte stream using the data flow task. I do not want to use a source database because my data is not flowing from one table to another. I really just want to take my populated variables and convert them to a byte stream which i can then insert successfully into a sqlite database. The issue is, i cannot use a dataflow task without a source database.
My work-around so far has been to declare a source database/table and only one column (but never use it in the data flow). This works fine and I am unable to insert the row into sqlite using my pre-set variables, but i am left with a somewhat annoying message in my Output log every time i do this:
Warning: 0x80047076 at , SSIS.Pipeline: The output column "" (117) on output "OLE DB Source Output" (11) and component "OLE DB Source" (1) is not subsequently used in the Data Flow task. Removing this unused output column can increase Data Flow task performance.
Anyone know of a good way to get this warning not to show up?
In your dataflow choose a Script Component.
When prompted to choose Source, Destination, or Transformation, choose Source.
Add your pre populated variables to the CustomProperties.ReadOnlyVariables section of the script tab.
Go to the Inputs and Outputs section.
Add a column to the default output for each of your variables.
In your script (if using C#) put something similar to the following in the CreateNewOutputRows() section
Output0Buffer.AddRow();
Output0Buffer.ContainerName = Variables.ContainerName;
Output0Buffer.TaskName = Variables.TaskName;
Output0Buffer.TaskStartDate = Variables.ContainerStartTime;
Save your script.
Connect your script component to your destination object.
If this is causing your package execution to get failed, you got an option of ignoring these warnings/errors..
Just double click the Source block in Dataflow and navigate to the last tab("Error OUtput") in left side pane and you need to select the option to ignore the errors. (I dont know eactly what phrase in that option will do it )
