I have a table of healthcare claims data for which I would like to have a unique identifier for each row. I have acheived this in the past by creating a temporary table with an identity column and then inserting those rows into my final table. I use a variable to find the maximum value in the destination table. The data type in the final table, in this example, is bigint.

I will receive claims data on a recurring basis from various clients and I am creating a procedure to add the new claims to an existing table.

I was wondering if I could directly insert the claims into the destination table which will have an identity column. I tried to use NEWID() and that did not work.

Here is a sample of my insert statement:

Insert Into DEV..REBATEPRIMARY
Select NEWID(),
[company name],
[subscriber ID],
[process date],
etc.
from DEV..RBT_test

Thanks

If the target table has an identity column defined, then don't include it in your insert statement and it will be automatically populated at the time of insert.

Wow, that was too easy.

Thanks so much. Tested that and it worked perfectly.

Yes, we all know too well that sometimes the hardest problem we work on is right in front of our face. Hehe
