I am creating a SSIS package that involves a where clause as:
WHERE effectiveDate >= #effectiveDate
Therefore, I defined #effectiveDate at the package level so that I can pass in value from a sql command using a different connection.
At the OLE DB source, I selected 'SQL command', and put the code as
Select ... FROM ...
WHERE effectiveDate >= ?
When I click on the 'parameters', an error appears:
'Parameters cannot be extracted from the SQL command. blablabla... use "SQL command from variable"...'
I am trying to avoid using SQL command from variable and try to locate the problem since I should be able to pass in variable.
Can anyone help? Thanks a lot!!
When building an OleDbCommand, you should actually name the parameter as the package is expecting, such as
OleDbCommand cmd = new OleDbCommand( "select ... from... where... eff > #yourPkgPameterName");
cmd.Parameters.AddWithValue( "#yourPkgPameterName", whateverValueToSend );
It's been a while for SQL-based parameters and don't remember if the AddWithValue() method is expecting the "#" or not... may need to try without it if it fails.

I need to get last processed date of SSAS cube in SSIS and save it into a variable.
I've tried a "Execute SQL task":
SELECT LAST_DATA_UPDATE as LAST_DT FROM $system.mdschema_cubes
WHERE CUBE_NAME = 'CubeName'
It works ok in MSSQL management studio MDX query window but in SSIS it says: Unsupported data type on result set binding.
Then I've tried:
WITH MEMBER [Measures].[LastProcessed] AS ASSP.GetCubeLastProcessedDate() SELECT [Measures].[LastProcessed] ON 0 FROM [CubeName]
And it says '[ASSP].[GetCubeLastProcessedDate]' function does not exist.
Any ideas how to do this?
Thank you
A linked server might be your best option;
Create the linked server with the following, changing as appropriate:
EXEC master.dbo.sp_addlinkedserver
#server = N'LINKED_SERVER_OLAP_TEST', --Change to a suitable name
#srvproduct='', --Creates the productname as blank
#provider=N'MSOLAP', --Analysis Services
#datasrc=N'localhost', --Change to your datasource
#catalog=N'TESTCUBE' --Change to set the default cube
Change the data source of your Execute SQL Task to make sure it is pointing to any of the databases where the linked server is hosted, I.E. don't use an analysis service datasource use a standard OLE DB. Then have the following in your execute SQL task (Changing as appropriate).
SELECT *
FROM OpenQuery(LINKED_SERVER_OLAP_TEST,'SELECT LAST_DATA_UPDATE as LAST_DT FROM $system.mdschema_cubes
WHERE CUBE_NAME = ''CUBENAME''')
Set the variable to be DATETIME and the result set to be single row.
There may well be other ways to do this, however I have always found this method the most straight forward.
I have the following SQL Command in an OLE DB Source, in a data flow task:
Select Top 5000 *
From ProcessHistory.ScribeDeadZone1
Where ScribeDeadZoneId > ?
At the moment this works fine. However, I'd like to replace the 5000 with a variable. I can't seem to get the syntax right because everything I try results in an error when I click the Parameters button to set the parameter. I've tried
Select Top ? * and Select Top (?) *. Is this possible to do?
You need to build the SQL statement in a variable and then use the SQL Command from Variable option when defining the data source.
I am trying to do a very simple sql select statement from a MySQL database:
Dim lDatabase As Database = DatabaseFactory.CreateDatabase("FTP")
lSqlString = String.Format(CultureInfo.CurrentCulture, "SELECT monthends.web_usr FROM monthends")
lDBCommand = lDatabase.GetSqlStringCommand(lSqlString)
lUsers = lDatabase.ExecuteDataSet(lDBCommand)
And on the execute dataset line I receive the following ODBC Exception:
In order to evaluate an indexed property, the property must be qualified and the arguments must be explicitly supplied by the user.
I don't get it. This is the simplest of simple sql statements and it has all worked just fine in the past, why doesn't this work anymore???
Thanks in advance!
What was going on was that there was an incorrect version of the MySQL ODBC 3.5xx driver installed. I contacted the DB Admin and got the correct version, it all works now as it should.
I am trying to write ETL that collects data from many identical server into a central repository. What I'm trying to do is write one package with source address, user id and password as parameters and execute the package once per server to be copied.
Is this doable? How can I use parameters to create a source?
I meant to ask how to parametrize the connection manager (is that even a real word?), not where to store the connection parameters. The answer is simple:
Create package parameters for Server, Database, User ID and Password
Create a connection manager as part of defining a data flow component
once a connection is defined, right-click on the connection manager at the bottom of the package design screen and select "Parametrize".
Select "ServerName" in the property drop-down
Select "Use existing parameter" or create new parameter if skipped step 1
If using existing parameter, select it from the drop down
Click OK to save (gotta do it after each parameter)
Repeat steps 4-7 for the rest of the parameters
You can store parameters in a table. Query the table with a sql task and store the results in a object variable. You can then use this variable in a for loop. Use expressions in SSIS to change values of your connection during each loop iteration.
Several books outline this method. Here is a code example.
Here are some steps - hopefully I didn't miss anything. You mention a server "Address", but I'm not sure exactly what you are trying to do. This example queries multiple sql servers.
You create the variables, SQL_RS with type of object, SRV_Conn with type of string. This holds my servername. In the execute SQL task, I have a query which returns the names of sql servers I want to query. Then set the following properties:
SELECT RTRIM(Server) AS servername
FROM ServerList_SSIS
WHERE (Server IS NOT NULL)
and coalesce(exclude,'0') <> 'True'
and IsOracle is Null
Execute SQL Task > General > ResultSet = "Full Result Set"
Execute SQL Task > Result Set Tab "Result Set Name = 0", Variable Name = "User::SQL_RS"
So we have a list of server names in the SQL_RS variable now.
ForEach > Collection > Enumerator = "Foreach ADO Enumerator"
ForEach > Collection > Enumerator Configuration > ADO Object source Variable = User::SQL_RS
This maps the first column of the SQL_RS object to the SRV_Conn variable, so each iteration of the loop will result in a new value in this variable.
ForEach > Variable Mappings > Variable = User::SRV_Conn, Index = 0
Inside the ForEach are some other sql execs, performing queries on sql databases, so I need to change the ServerName of my 'MultiServer' connection. I have another connection for the initial query that got me the list of servers to query. Making the connection dynamic is done in properties of the connection - right-click the connection > properties. Click the ellipses to the right of the expressions.
Connection > Properties > Expressions > Property = ServerName, Expression = "#[User::SRV_Conn]"
Note: The index value of 0 for the variable mapping works for Native OLEDB\SQL Server Native Client. If you're using another db provider, you may need to use other index types - this makes setup more confusing.
OLEDB = 0,1
ADO.NET = #Varname
ADO = #Param1, Param2
ODBC = 1,2

I have a lot of services which query the database. All of them work fine but one service calling a stored procedure gives me following error:
Could not find server 'dbo' in
sys.servers. Verify that the correct
server name was specified. If
necessary, execute the stored
procedure sp_addlinkedserver to add
the server to sys.servers.
I have not idea why all the other stored procedures work fine and this one not...
By the way, I use SubSonic as data access layer.
Please run select name from sys.servers from the server which you mentioned as default server in configuration file.
Here in name column values should match with your server names used in the report query.
e.g serverXXX.databasename.schema.tablename
serverXXX should be there in the result of select name from sys.servers otherwise it gives error as got.
It sounds like there is an extra "." (or two) in the mapping - i.e. it is trying to find server.database.schema.object. Check your mapping for stray dots / dubious entries.
Also make sure that the server name matches what you think it is. If you rename the host that SQL Server is running on, you need to rename the SQL Server, too.

I had another issue with the same exception so I'll post here if someone stumble upon it:
Be careful if you specify the server name in synonyms. I had a different server name on my staging machine and production and it caused the same 'cannot find server'-error.
(Guess you shouldn't use synonyms that much anyway but it's useful in some migration scenarios)
In my case i was facing same issue with following ,
SqlCommand command = new SqlCommand("uspx_GetTemplate", connection);
but after adding square bracket to stored procedure name it get solved.
SqlCommand command = new SqlCommand("[uspx_GetTemplate]", connection);
