getting out parameter from mysql stored procedure in java

Question

I am having problem retrieving OUT parameter from mysql stored procedure in java.

CALL proc_after_topic_add(\'newtest\',@result);
SELECT @result;
         


        

Answer 1

Error in this line

 cstmt.registerOutParameter(2, java.sql.Types.INTEGER);

change like this

 String sql = "CALL proc_after_topic_add(?,?);";
 cstmt.registerOutParameter(2, java.sql.Types.INTEGER);
