Problem with CallableStatement

Question

Hello,
I have a problem with the following code, while trying to execute a sybase stored procedure . The parameters namePar and codePar are strings, which I have hardcoded in the first prepareCall. I don't get data from the database using both of the prepareCall statements, but I have results when I execute the call from the first statement in the database IDE. Do you see anything wrong with this code ?
Thanks
sql = dbconn.prepareCall("{call sp_SEARCH_Stocks(21,3, 0, '[][3*]',null, null,'[][8*]',null,null)}");
            sql = dbconn.prepareCall("{call sp_SEARCH_Stocks(? ? ? ? ? ? ? ? ?)}");
                         sql.setInt(1,21);
                         sql.setInt(2,3);
                         sql.setInt(3,0);
                         sql.setString(4,"'[][" + namePar +"*]'");
                         sql.setString(5,null);
                         sql.setString(6,null);
                         sql.setString(7,"'[]["+codePar + "*]'");
                         sql.setString(8,null);
                         sql.setString(9,null);

Answer 1

The first statement has commas
The second doesn't.
