ResultSet problem

I am trying to insert one table data to another table. But if the second table is empty it is giving a runtime error that "before start of resultset". How to rectify that? In my condition I gave to insert into the table if first table id is not equal to second table id and if the count(*) is equal to zero. But it is not inserting into the table. Where am I going wrong. Please help me.
