grinder JDBC parallel threads test

Hi All:

I have question about parallel threads test JDBC driver. Such as:

I set 50 threads for parallel threads test JDBC driver. 25 threads run Database query, 25 threads run Database insert.

Such as:

class TestRunner:
    def __call__(self):
        connection = None
        insertStatement = None
        queryStatement = None
 
        try:
            connection = getConnection()
            insertStatement = connection.createStatement()
 
            test1.record(insertStatement)
            insertStatement.execute("insert into grinder_fun values(%d, %d)" %
                                    (grinder.threadNumber, grinder.runNumber))
 
            test2.record(queryStatement)
            queryStatement.execute("select * from grinder_fun where thread=%d" %
                                   grinder.threadNumber)


Thanks!
