I get exception while executing following query

My code runs perfectly If I execute only first query.
I also checked for datatypes matching and table formats.

You need to call resultSet.next() before calling resultset.getInt(12).

Also, if you only use that one field, why use "select *"? You could write a more specific query.

agentid = 1;
agentid = resultset.getInt(12);
agentresultset=agentstatement.executeQuery("select * from db_finalagents where id="+agentid);[/code]



please make sure your SQL statement .

i think your problem is, you put a space after "and cost <= " :
so please use the following ResultSet SQL :
ResultSet rs = statement.executeQuery("select * from db_finalreal where cost >=" + minValue + " and cost <="
+ maxValue + " and city='"+ city + "' and type='"+ type+"'");

and write :
rs.next();

Thank's
Sorry my english isn't too good
 
It is sorta covered in the JavaRanch Style Guide.
