如何在存储过程中调用存储过程(带有2个参数)？

Question

我有相同参数(服务器名称和日期)的存储过程.我想编写一个存储过程并在该SP中执行它们(称为SP_All).

CREATE PROCEDURE [dbo].[SP_All]
AS
BEGIN
exec sp_1   @myDate datetime, @ServerName sysname
exec sp_2   @myDate datetime, @ServerName sysname
exec sp_3   @myDate datetime, @ServerName sysname
exec sp_4   @myDate datetime, @ServerName sysname
END
Go 

错误:必须声明标量变量"@myDate".

Answer 1

我在这里看到两个问题:

1. 您的过程显然需要两个参数,@myDate并且@ServerName您还没有声明.通过在过程名称和AS之间添加名称和类型来执行此操作.

2. 将sp_1调用到sp_4时,无需再次指定参数的数据类型(已由声明处理,请参见第1点).

   CREATE PROCEDURE [dbo].[SP_All]
       @myDate datetime,
       @ServerName sysname
   AS
   BEGIN
       exec sp_1 @myDate, @ServerName
       exec sp_2 @myDate, @ServerName
       exec sp_3 @myDate, @ServerName
       exec sp_4 @myDate, @ServerName
   END
   

Answer 2

试试这个——

CREATE PROCEDURE [dbo].[SP_All]

       @myDate DATETIME
     , @ServerName SYSNAME

AS BEGIN

     EXEC dbo.sp_1 @myDate, @ServerName
     EXEC dbo.sp_2 @myDate, @ServerName
     EXEC dbo.sp_3 @myDate, @ServerName
     EXEC dbo.sp_4 @myDate, @ServerName

END
