Select @ReturnCOID = COID from Order.
Note that this must return only one row.

If more than one row can be a candidate, either use a WHERE clause, TOP 1, MAX() with GROUP BY, etc.

"Note that this must return only one row"

If that is possible causing problems there are ways around that , but see they still give a correct value in all cases for what you intend to do.
Some examples
Select @ReturnCOID = max(COID) from Order

Open in new window

or
Select @ReturnCOID = top 1 COID from Order order by orderdate desc

Open in new window
