When I try to export to a txt, it doesn't come out with the column names.

[@learnssis]

Oh ideally it should. I normally use Union All transformation for merging the 2 data sets into a single data set as we don't need to sort the data before Union All, try using that and see if column names comes out.

[@mduoonus656]

very good guide line sir

[@learnssis]

Good to know that you liked it. Thanks.

[@pranavratnalikar]

Sir I’m getting an error “does not metadata for associated output column”

[@learnssis]

Can you just delete the transformation and add it back and try again ? Also try to close and reopen the SSIS package. Thanks.

[@learnssis]

If you want to learn how to perform merge join operation, then you can see below video which tells you how to perform merge join.

If you still have any question, let me know.

[@sriniwaaskorampalli8145]

sir the only diff btwn merge and union all is "Sorting"?

[@learnssis]

In addition to this difference, there is another difference that, Union All accepts more than two inputs while Merge transformation doesn't.

[@MerinNakarmi]

Looks like the data were already sorted in the source. Still it requires sort, which is an expensive operation :(

[@learnssis]

Yes it is. Try to use Union All Transformation if possible.

[@rashmiranjansahu3281]

[@learnssis]

Thanks Rashmi for your comment. Yeah sure I will be working to create more videos on MSBI.

Every time you run this solution the data in the destination SQL server will be duplicated. Where do i write a 'DROP IF EXISTS' command ? Other solution would be to create a new table2 so i´d have the orininal and the updated. How can it be done?

[@learnssis]

In this ssis package we are inserting the data to MergeTransformationData inside the data flow task. So if you will rerun it, then it can insert duplicate data to MergeTransformationData table.
So you can truncate table MergeTransformationData using an execute sql task before the data flow task.
