I want to get a column value from the first query and pass that value to the next query.

If you run Q1:select deal_id from deal_XX then you probably get more than one row. Therefore, there are two issues:

  1. Having select *, (subselect) from tableX then the subselect has to return always just one value for each row of the tableX. Since you have Q1 as a subselect, your query fails.

  2. The same issue is when you have select * from tableX X where X.y = (subselect). Again, query processor expects you to provide a subselect returning just one value for each row of TableX and you have Q1 returning many rows.

The solutions depend on what you are trying to achieve. The second issue could be possibly fixed using od.deal_ID IN (select deal_id from deal_XX) meaning that you want rows where deal_id can be found in the list of deal_ids returned by deal_XX.
