SQL Server默认会在完成存储过程时自动返回一个0值。 为了从存储过程向调用代码传递返回值,只需要使用RETURN语句。 RETURN [] 要特别注意的是:返回值必须是整数。 关于RETURN语句,最重要的是知道它是无条件地从存储过程中退出的。无论运行到存储过程的哪个位置,在调用RETURN语句之后将不会执行任何一行代码。 下面

存储过程(Stored Procedure)是在大型数据库中,一组为了完成特定功能的SQL 语句集,它存储在数据库中,一次编译后永久有效,用户通过指定存储过程的名字并给出参数(如果该存储过程带有参数)来执行它。存储过程是数据库中的一个重要对象。在数据量特别庞大的情况下利用存储过程能达到倍速的效率提升 ---来源于百度百科...
