Question

我正在研究用于测试MySQL DB负载测试的Grinder框架。我能够连接MySQL数据库，但无法执行查询，我也没有收到任何错误消息。我的问题是如何在grinder框架中执行查询（Grinder将在Jython上运行）。

请找到下面的Jython脚本和程序正在执行“打印”test1记录“”步骤，之后它简单地跳过步骤，那个程序中的任何错误就像在查询中一样？

from java.sql import DriverManager
from net.grinder.script.Grinder import grinder
from net.grinder.script import Test
from com.mysql.jdbc import Driver

test1 = Test(1, "Database insert")
test2 = Test(2, "Database query")

#Load the MySQL JDBC driver.
DriverManager.registerDriver(Driver())

def getConnection():
    return DriverManager.getConnection("jdbc:mysql://localhost:3306/test",
"root", "Sasken@123")

def ensureClosed(object):
    try: object.close()
    except: pass

class TestRunner:
    def __call__(self):
        connection = None
        insertStatement = None
        queryStatement = None
        print "connection"
        try:
            connection = getConnection()
            insertStatement = connection.createStatement()
            print "try connection"
            test1.record(insertStatement)
            print "test1 record"
            insertStatement.execute("insert into testing values(%d)"
(100))
            print "insert"
            test2.record(queryStatement)
            print "test2 record"
            queryStatement.executeQuery("select * from testing")
            print "select"
        except SyntaxError:
                         print "can\'t execute db"

        finally:
            ensureClosed(insertStatement)
            ensureClosed(queryStatement)
            ensureClosed(connection)

Thanks Advance.

使用com.mysql.jdbc导入驱动程序与Jython建立MySQL连接
