       ,[LastUpdateUser]
       ,[module]
       ,[isactive])
 SELECT
        ( 1
        , (SELECT MAX(DisplayOrder) + 10 FROM tMrMenu)
        , 'EDM Summary Text'
        , 'EDM Summary Text'
        , '/Offline/Reports/EdmSummaryText'
        , 'cli.gif'
        , GETDATE()
        , 'Garry.Bargsley'
        , GETDATE()

Answer 1

你有额外的括号：

INSERT INTO tMrMenu
       ([ParentId]
       ,[DisplayOrder]
       ,[ItemName]
       ,[ItemDescription]
       ,[ItemURL]
       ,[ItemImage]
       ,[CreateDate]
       ,[CreateUser]
       ,[LastUpdateDate]
       ,[LastUpdateUser]
       ,[module]
       ,[isactive])
 SELECT
        1
        , (SELECT MAX(DisplayOrder) + 10 FROM tMrMenu)
        , 'EDM Summary Text'
        , 'EDM Summary Text'
        , '/Offline/Reports/EdmSummaryText'
        , 'cli.gif'
        , GETDATE()
        , 'Garry.Bargsley'
        , GETDATE()
        , 'Garry.Bargsley'
        , 'MR'
        , 1

Declare @max int
