Solution 1

Use In Instead of =

i believe your query will look like this

SQL

Select * from tbl1 where col1=(select col1 from tbl2)

Use In operator here

SQL

Select * from tbl1 where col1 in (select col1 from tbl2)

Solution 2

You have to execute each sub-query to know which returns more than one row.
