Need help with an SQL query without using a cursor
Hi there to all SQL gurus So, here is the scenario. I have a #temp table in one of my SQL stored procedures which has only 2 columns, say Customer ID and Profile ID, and it has the below data Customer ID Profile ID 100001 ABCD001 100001 ABCD002 100002 ABCD001 100002 ABCD002 100003 ABCD001 I need to write a query which selects only the Profile ID which is mapped to all the Customer IDs. In this case Customer ID 100001 and 100002 have both ABCD001 and ABCD002, but Customer ID 100003 has only Profile ID ABCD001, so, the output of the SQL should have only ABCD001. How do I do this without using a CURSOR? Would a CTE help? I am not very familiar with CTE, so if the solution is using a CTE, please give your suggestions in more detail. Thanks in advance
