Creating a Data Conversion You Excel columns should be in the same data type as the database columns.If they are not the same data type you will get errors, but fear not.It should look similar to the following: Modifying the OLE DB Source Double-click the OLE DB Source and uncheck all of the boxes except ID.

You can then use an Execute SQL task to run your update in a more organic manner.

Set up your data flow as shown above to pull in the data to a staging table, then you can run a single UPDATE statement: The advantage here is that you’re executing the expensive UPDATE statement once for each table rather than once for each row affected.

Of course, there are some situations that explicitly disallow the use of staging tables in destination systems.

If storage or access restrictions keep you from using this method, you may have to use the row-by-row insert, so be aware that it’s going to be a bottleneck.

The UPDATE statement can change data values in single rows, groups of rows, or all the rows in a table or view.

It can also be used to update rows in a remote server by using either a linked server name or the OPENROWSET, OPENDATASOURCE, and OPENQUERY functions, as long as the OLE DB provider used to access the remote server supports updates.

So let’s say our source retrieves 100,000 rows into the data flow: the downstream UPDATE command will be executed 100,000 times!
