                   WHERE   ( TBLTicketBranchs.ResellerID = @ResellerID   --without flag (@flag=0)
                             AND ( TBLTicketAnswers.Answer LIKE N'%'

                                   OR @Keyword IS NULL

推荐答案

试试这个....

Try this....

SELECT Distinct  ti.TicketID, ti.UserID, ti.AttachFile, ti.HasFile, ti.Title, ti.Question, ti.Flag, ti.InsertDate, tb.BranchName, ta.AnswerID, ta.Answer, tu.UserName, tu.UserOwner, tu.Corporation
FROM  dbo.TBLTicketBranchs tb
INNER JOIN dbo.TBLTickets ti ON tb.BranchID = ti.BranchID
INNER JOIN dbo.TBLUsers tu ON ti.UserID = tu.UserID
LEFT OUTER JOIN dbo.TBLTicketAnswers ta ON ti.TicketID = ta.TicketID
WHERE   tb.ResellerID = @ResellerID   --without flag (@flag=0)
AND ( ta.Answer LIKE N'%' + @Keyword + '%'
      OR @Keyword IS NULL
      OR ti.Title LIKE N'%' + @Keyword + '%'
      OR @Keyword IS NULL
      OR ti.Question LIKE N'%' + @Keyword + '%'
      OR @Keyword IS NULL
      OR tu.UserName LIKE N'%' + @Keyword + '%'
      OR @Keyword IS NULL
     )

在编写联接时尝试使用别名......

Try using Alias Names While Writing Joins...
