Autofill an Integer Column

[mekohler]

Hi, I'm importing a table from another data source, deleting an existing table in a SQL database and replacing the data with the new imported data. My problem is that in the destination table there needs to have a primary key, an integer column. Is there a way that when I'm exporting the new data to the destination table that I could populate an integer column with a random number or auto number?
Thanks,
Michael

Easiest way is to change that primary key to be a identity one, and change it back once load finished

Failing that.

option 2 - not feasible if volumes are high
insert into a temp table with the field defined as identity and then insert into final table

option 3 - add a transform step to your dataflow and add a incremental value to that column

option 4 - on the data source, if it is a SQL db, join your source data with a numbers table and use that as the required number
