通过添加除周末之外的其他天触发

Question

创建一个与columnA（日期类型）更新时相同的触发器ColumnB（日期类型）应更新为8天，并且不包括周末。 下面是我的SQL查询，请帮忙。 谢谢， 桑迪普

   create TRIGGER Test
       ON  TableName
       AFTER INSERT,UPDATE
    AS 
    BEGIN
        -- SET NOCOUNT ON added to prevent extra result sets from
        -- interfering with SELECT statements.
        SET NOCOUNT ON;

        IF UPDATE([Column A])
        BEGIN
            UPDATE  [dbo].[TableName]
            SET     [Column B]= dateadd(day,8,i.[Column A])
            FROM    inserted i
            INNER JOIN [TableName] t ON i.ID=t.ID
            LEFT JOIN deleted d ON i.ID=d.ID
            WHERE   d.ID IS NULL AND i.[Column A] IS NOT NULL -- Row was inserted
            OR      d.ID IS NOT NULL -- Row was updated
        END
    END
    GO
