如何在存储过程中调用存储过程(带有2个参数)?

问题描述

我的存储过程具有相同的参数(服务器名称和日期).我想编写一个存储过程，并在该SP(称为SP_All)中执行它们.

I have stored procedures with same parameters (server name and date). I want to write a stored procedure and Exec them in that SP (called it 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".

error: Must declare the scalar variable "@myDate".

推荐答案

我在这里看到两个问题:

I see two issues here:

1. 您的过程显然带有两个参数，@myDate和@ServerName，您尚未声明.为此，请在过程名称和AS之间添加名称和类型.

2. 在将sp_1调用到sp_4时，无需再次指定参数的数据类型(声明已处理了该数据类型，请参见第1点).

1. Your procedure apparently takes two parameters, @myDate and @ServerName, which you have not declared yet. Do so by adding the names and the types between the procedure name and AS.

2. When calling sp_1 to sp_4, there is no need to specify the data type of the parameters again (that's been taken care of by the declaration, see point 1).

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
