In this article we will show you, How to Delete Data using OLE DB Command Transformation in SSIS. Please refer OLE DB Command Transformation in SSIS article to understand How to insert data using OLE DB Command Transformation and Update Data using OLEDB Command Transformation article to understand the Update operations.
Before we start designing the SSIS Package let me show you the Destination Table in [SSIS Tutorials] Database
If you observe the above Data we have NULL values for the English Description column data. In this example we will delete all the rows with No description using SSIS OLE DB Destination Transformation
Delete Data Using OLEDB Command Transformation in SSIS
Drag and drop the Data Flow Task from toolbox to control flow region and rename it as Delete Data using OLEDB Command Transformation in SSIS 2014.
Double click on it and it will open the data flow tab. Next, Drag and drop OLE DB Source and OLE DB Command transformation from toolbox to data flow region.
Double click on OLE DB source in the data flow region will open the connection manager settings and allows us to select the required table.
And the SQL Command we used in the above screenshot is
FROM [SSIS Tutorials].[dbo].[Products]
WHERE [EnglishDescription] IS NULL
Click on columns tab to verify the columns. In this tab we can uncheck the unwanted columns also.
Drag the OLE DB Source Output arrow on to the OLE DB Command Transformation to perform transformations on the source data.
STEP 5: Double click on the OLE DB Command Transformation will open the Advanced Editor for OLE DB Command to configure it.
Within the Connection Managers tab we are selecting the already created OLE DB Connection from the list as shown below. Please refer the OLE DB Connection Manager in SSIS article to understand, How to configure the connection manager.
Within the Component Properties we have to write the SQL Statement we have to perform. Please select the SqlCommand property and click on the browse button (… button)
Once you click on the browse button, a String Value Editor window will be opened to write the SQL Statement. In this example, we are deleting the values in the products table.
SQL Statement we used in the above screenshot is
DELETE FROM [SSIS Tutorials].[dbo].[Products]
WHERE [ProductKey] = ?
Within the Column Mapping we have to assign the appropriate column name to the parameters.
From the above screenshot you can observe that, Param_0 represents first question mark which is [ProductKey] column from source.
click ok to finish configuring the Delete Data Using OLEDB Command Transformation In SSIS 2014 package. Let us Run the package
Let us open the SQL Server Management Studio and check whether we successfully deleted the rows with No description or not.
Now let us look at the Final data. If you observe the ProductKey column, it started with 210 instead of 1 because all the rows before that are deleted by the OLE DB Command Transformation
