In SSIS I need to import data from table, that has column names like this N°Projet, PR Réalisé. During set up of OLE DB Source everything is OK. I can run this package from Visual Studio and load data. But when I deploy the project and set up sql server job to run it, I get error.
I can see that query in OLE DB Source has changed.
What I set up:
SELECT
[N°Projet] AS ProjectNumber
,[N°Projet] AS CurrentProjectNumber
,[Projet] AS ProjectName
What I see when I recreate SSIS project from sql catalog
SELECT
[N°Projet] AS ProjectNumber
,[N°Projet] AS CurrentProjectNumber
,[Projet] AS ProjectName
And therefor my query in OLE DB Source is invalid.
Any idea how to fix this issue without changing source table columns?

In SSIS, using OLE DB command and moved in to another step column
mapping "it is showing only name else blank and i have to map all four column through insert under OLE DB command , even i can share error with this blog.I am using MS BI and SQL-2008 R2 version.Kindly help me out.
I have created a SSIS package in order to transfer datas from ACCESS to SQL SERVER.
Source > SQL Command from "mdb" file joinning two tables
Destination > Flat table in SQL Server
I'm performing the JOIN in the source SQL Command because of the number of records in the ACCESS tables (~500k).
I tried to use SSIS join but it take ages doing the ORDERING before JOIN.
While running package in VS2010, it works great.
But after deploying and executing the package on my SQL Server 2014 the following error occurs.
No column information was returned by the SQL command.
Returned validation status "VS_NEEDSNEWMETADATA"."
I'm pretty sure my SQL command is correct (Working in VS and the preview button in the editor show me records).
I tried to disable ValidateMetadata but the same error still occurs, but at execution this time.
In the SQL Server 2014 I have other packages calling ACCESS data (But without join) and it works properly.
Thanks for your help,
Q.
ValidateMetadata is (generally) a good thing.
This error is being caused by the metadata on your source or destination (it's unclear from your question) being different.
At a guess, at least one of the columns in your SQL2014 database is of a different datatype (or length, or is nullable etc.) - there is a difference either way.
I am planning on importing data into Azure SQL database using SSIS package. I know I can do that with OLEDB Source and Destination but I also want to check if the database and tables exist and if not - create them. I am planning on using Execute SQL task to create database and tables, but how do I first check if they already exist?
So if database and tables exist, I will run data flow task to transfer the data, but if they do not exist - run Execute SQL task to create database and tables and then run data flow task.
How can I accomplish that?
Create an OLE DB connection manager to the server and master database on it. Apply this connection manager for the next two steps.
Create two SQL tasks in a container. The first SQL task will check to see if the database exists. You can pass the database name as a variable to it and apply it in the SQL example like that shown below. The "?" is the database name variable.
IF NOT EXISTS(SELECT * FROM sys.sysdatabases where name=?)
-- create database
Then for the second SQL task apply something like the following in which the database and table name are passed as variables. But, in difference to the previous SQL, you can apply an expression for defining the SQL.
"IF OBJECT_ID(N'" + <#DatabaseName> + "dbo." + <#tablename> + ", N'U') IS NULL
CREATE TABLE " + <#DatabaseName> + "dbo." + <#tablename> + "
(
Field1 VARCHAR(20) NOT NULL
,Field2 TINYINT NOT NULL
);"
I'm not very familiar with Azure or SSIS, but in SQL Server you can check to see if an object exists like this:
IF OBJECT_ID('dbo.UserTable', 'U') IS NULL
-- Doesn't Exist.
I hope this helps in some way.
SSDT (the database tool, not the SSDT-BI product suite) uses a declarative model to manage and deploy database schemas. You can get SSDT here.
Once you create a new SQL Server Database Project, you can import an existing database schema. In the database properties, you will define your target database as Azure. When you build the project, it creates a dacpac file as output. This file is an archive that contains the definition of your database.
SSDT comes with a utility called sqlpackage.exe, which you can learn about here. You can then pass in your dacpac file and target server and have the utility "publish" the database. If the database and schema are there are match up, it will do nothing. If it does not exist all objects will get created. If the schema is different than expected, it will update the schema according to how it is defined in the project.
SSDT has loads more benefits than this, but for your case, it will simplify the process and make it far more maintainable.
BTW, if the database does not exist, you may need to put delay validation on your connection managers and tasks in the rest of the package so it does not fail validation. Or better, create a master package that first executes the sqlpackage process task and then calls your loading package as a child package.
I'm using a procedure that uses a table variable to fetch relevant data from my DB, and then returns whatever is stored in that table variable to my data flow.
My OLE DB Source is only designed to run the SQL command EXEC FetchData_prc.
It shows the required columns in the Source Editor, and it also lets me do mapping, preview and all of that.
YET, when running the package, it throws the error: [OLE DB Source [1]] Error: A rowset based on the SQL command was not returned by the OLE DB provider.
You may try to set nocount on on your stored procedure to prevent the server from returning the row count. This could be mistaken by SSIS as the returned result set. See this
I am trying to retieve data from a MySQL table and insert into a SQL Server table using ADO .NET connections in SQL Server 2008 SSIS. In my data flow task I have an ADO .NET Source which queries the MySQL table (select all invoices) and an ADO .NET Destination which inserts the data in my SQL Server table. Now, I would like to add a parameter in my data source so that I only select the max(invoiceNumber) retrieved from my SQL Server table. I have performed a similar task using "OLE DB Command" but the problem is that I need to query a MySQL database. Any ideas how I can achieve this?
I found that the only way to use parameter with the ADO.NET Data Source is this workaround:
Go to the Flow Control and selenct the Activity Flow containing your ADO.NET source.
In the properties window you can see the ADO.NET source Sql Command
Go to expression and select the properties: [YOU SOURCE NAME].[SqlCommand] and then edit the expression using variables to simulate parameters
Set Data Access Mode in ADO.NET Source to SQL Command and write the query.
You shoudn't have to add a parameter:
select *
from invoices
where invoiceNumber = (select max(invoiceNumber) from invoices)
The above works in SQL Server. I'm assuming that the same query will work in MySQL
