1、脚本协议：选择web service

2、脚本：

Action()

{
int NumRows=0;



//建立连接
lr_db_connect("StepName=DatabaseConnection",
"ConnectionString=Data Source=192.168.1.251;Initial Catalog=MY_test;Persist Security Info=True;User ID=sa;Password=test1",
"ConnectionName=MeCon",
"ConnectionType=SQL",
LAST );

//执行SQL
NumRows = lr_db_executeSQLStatement("StepName=PerformQuery",
"ConnectionName=MeCon",
// 数据库语句

"SQLStatement=SELECT TOP 1 SendContent= SUBSTRING(SendContent,CHARINDEX(':',SendContent)+1,6) FROM si_sms ORDER BY id DESC ",

"DatasetName=MyDataset",
LAST );
lr_output_message("The query returned %d rows.", NumRows);


//打印查询结果
/*
lr_db_dataset_action("StepName=PrintDataset",
"DatasetName=MyDataset",
"Action=PRINT",
LAST );*/


//获取短信内容
lr_db_getvalue("StepName=GetValue",
"DatasetName=MyDataset",
"Column=SendContent",
"Row=current",
"OutParam=MyOutputParam",
LAST );

// 输出验证码
lr_output_message("The value is: %d", lr_eva l_string("{MyOutputParam}") );




//关闭链接
lr_db_disconnect("stepname=Disconnect","connectionname=MeCon",LAST);

return 0;
}

3、输出结果：（验证码：664545）
