LoadRunner访问 Mysql数据库_MySQL

这里提供了几个公共函数，看名字大家都明白他们是干啥的。

Step3：Loadrunner里需要怎么编写写呢？

1、添加libmysql.dll到你的工程

2、把公共库添加到你的公共

3、vuser_init

vuser_init(){index = 0;

MySqlInit(); // 初始化数据库

return 0;}

4、vuser_end

vuser_end(){

MySqlUnit(); // 反初始化

return 0;}

5、Action

Action(){

int resultValue;

char cIndex[10];

char onceAccount[1024];

char insertQuery[22584];

index = index +1;

// 组合插入数据库的sql语句

strcpy(insertQuery, "INSERT INTO `t3db`.`role`(GroupID, RoleName, Account, BaseInfo, ExtInfo, LastModify) VALUES('1', '");

strcat(insertQuery, lr_eval_string("{Account}"));

strcat(insertQuery, itoa(index, cIndex, 10 ));

strcat(insertQuery, "', 'q1031', '111', '111','2013-02-28 20:42:33')");

strcat(insertQuery, ";/0");

lr_start_transaction("Insert");

resultValue = InsertValue(insertQuery); // 调用插入函数

if(resultValue != 0)

{

lr_end_transaction("Insert",LR_FAIL);

}else{

lr_end_transaction("Insert",LR_PASS);

}sleep(100);return 0;}
