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。 下面的...

You specify the return code for a procedure using the RETURN statement. As with output parameters, you must save the return code in a variable when the procedure is executed in order to use the return code value in the calling program. For example, the assignment variable @re...
A cursor output parameter can pass back a Transact-SQL server cursor. The procedure can have an integer return code.Applications must be able to handle all these outputs from stored procedures. The CALL or EXECUTE statement should include parameter markers for the return code...
