Question

我需要修剪一个搜索参数，这样当输入一个数字时，它会修剪结果，使得没有前导或拖尾空格。下面是SQL。我在语法上找到了很多资源，我只是没有理解如何修剪@SearchText变量。任何帮助是极大的赞赏。 @SearchText变量用作SSRS中的参数。谢谢

DECLARE @SearchText varchar(30)

select  Q.STATUS_EFF_DATE as DISP_DATE,
        Q.EXPIRATION_DATE as EXP_DATE,
        Q.STATUS as DISPOSITION,
        QL.PART_ID,
        QL.DESCRIPTION,
        QL.CUSTOMER_PART_ID,
        Q.NAME as CUST_NAME,
        Q.CUSTOMER_ID as CUST_ID,
        Q.ID as QUOTE_ID,
        QP.UNIT_PRICE,
        QP.QTY

from    Quote_LINE QL inner join QUote Q
         on QL.QUOTE_ID = Q.ID
        inner join QUOTE_PRICE QP
         on QP.QUOTE_ID = Q.ID
            and QP.QUOTE_LINE_NO = QL.LINE_NO

where   QL.PART_ID like '%' +@SearchText +'%'
        or QL.DESCRIPTION like '%' +@SearchText +'%'
        or QL.CUSTOMER_PART_ID like '%' +@SearchText +'%'

Answer 1

使用LTRIM删除leading空格并使用RTRIM删除trailing空格。

where   QL.PART_ID like '%' +LTRIM(RTRIM(@SearchText)) +'%'
        or QL.DESCRIPTION like '%' +LTRIM(RTRIM(@SearchText)) +'%'
        or QL.CUSTOMER_PART_ID like '%' +LTRIM(RTRIM(@SearchText)) +'%'

TRIM SQL搜索参数
