Python批量插入SQL Server数据库

因为要做性能测试，需要大量造数据到数据库中，于是用python写了点代码去实现，批量插入，一共四张表

简单粗暴地插入10万条数据

import pymssql
import random

__author__ = ‘sryan‘

class GenerateData:
    def __init__(self):
        print(‘init‘)
        self.conn = None
        self.cur = None

    def connect(self, host, user, password, database):
        try:
            self.conn = pymssql.connect(host=host, user=user, password=password, database=database)
            self.cur = self.conn.cursor()
        except Exception, e:
            print e.message

    def disconnect(self):
        try:
            if self.conn is not None:
                self.cur.close()
                self.conn.close()
        except Exception, e:
            print e.message

        for i in range(times):
            self.cur.execute(str_insert)
