我来自MySQL背景，最近开始迁移到SQL Server。

在我的生活中，我不能找到在SQL Server中执行以下操作的存储过程的示例： - 多线 - 包含输入和输出参数 - 设置存储过程中的一个输出参数

任何人都可以提供一些见解吗？即为什么以下不起作用？

Msg 156，Level 15，State 1，Procedure CHI_X2，Line 31
  关键字'PROCEDURE'附近的语法不正确。

Nsg 156，Level 15，State 1，Procedure CHI_X2，Line 56
  关键字'PROCEDURE'附近的语法不正确。

Msg 102，Level 15，State 1，Procedure CHI_X2，Line 112   'END'附近的语法不正确。

提前致谢！

当然，here's a basic introduction来输出参数。

这是它的短暂和甜蜜。请注意输出参数上的OUTPUT关键字：

CREATE PROCEDURE dbo.uspMyProc
@SomeParameter varchar(10),
@TheOutputParameter varchar OUTPUT
AS
  -- Do stuff
  SELECT @TheOutputParameter = somecolumn FROM something
  -- or
  SET @TheOutputParameter = someresult
RETURN

SQL Server错误中存储过程未解决
