我的存储过程中有以下代码。我已经宣布了@vReturnVar 但仍然显示＆＃39;必须声明标量变量＆＃34; @ vReturnVar＆＃34;。

Answer 1

放

DECLARE
@vReturnVar VARCHAR(10) 
,@vRCount VARCHAR(10)

存储过程的BEGIN之后

Answer 2

不应该包含“COUNT（）”

        SET @vRCount =(SELECT COUNT(Distinct Shift) 
                       From [dbo].[tblMMDLogEntry] 
                       Where Shift Like 'Night     ' And Date=(SELECT  MAX(Date)  
                       FROM [dbo].[tblMMDLogEntry]))

Answer 3

开始后宣布 DECLARE @vReturnVar VARCHAR（10）

肯定适合你

必须在存储过程中声明标量变量错误
