Question

I found a cursor being used in the below SQL and dynamic SQL. Profile brings up quite a bit of execution plans and I think it has to deal with this cursor. Is this a bad choice of SQL?

SET @SelectStmtSubHeader = 'SELECT DISTINCT
        dbo.dsb_testID(sh.GPCustomerID) AScursor -- RIGHT HERE
         PONumber,
        sh.GPCustomerID,
        .....

Answer 1

That’s not an example of a cursor.

A cursor needs to be…

DECLARE this_is_a_cursor CURSOR
FOR
  SELECT
    stuff
  FROM
    a_query

The snipped code you’ve shown appears to use a scalar function to derive a value, which it aliases to the word cursor. But having a field called cursor doesn’t make it a cursor.
