将Date参数传递给SQL脚本-错误：必须声明标量变量“ @dCutOff”，消息：137

Question

我收到错误消息：必须声明标量变量“ @dCutOff”。

我有以下脚本，我无法将DATE值（@dCutOff）传递给脚本2）和3）：

USE [V3]
GO

DECLARE 
    @dCutOff Datetime,
    @lDelete Bit

--Set the date date according to your cut off date

SELECT @dCutOff = CAST('01/01/2009' AS DATE)

SELECT * INTO TABLE040BKUP FROM TABLE040
SELECT * INTO TABLE41BKUP FROM TABLE041
DROP TABLE ADVANCED.TempTABLE041

--1) delete customer/account = blank
DELETE FROM Table003 WHERE C_UNO='' AND C_DOS=''
GO

--2) Table007
DELETE FROM Table007 WHERE T_DATETIME < @dCutOff
GO

--3) Table008
DELETE FROM Table008 WHERE T_DATETIME < @dCutOff
GO
