Question

我正在sql server中编写一个VIEW，并加入了几个带有内连接的表。

问题。

当我添加＆＃34;按nameRela.WNAME_INDIVIDUAL_LAST＆＃34;在内部联接语句中，下一个内部联接以红色突出显示，表示“内部＆＃39;
当我添加＆＃34;前1＆＃34;在select语句中，它还给出了红色错误。

使用带有多重内连接的select语句，添加＆＃39; Top 1＆＃39;的正确语法是什么？或者选择第一条记录并按

谢谢

select  top 500    
    rtrim(pendk_policy) as Id
    ,case (pendk_company) when '17' then 'BNR' when 'WP' then 'PENN' end as Company
    ,case rtrim(pendk_policy) when '' then '--' else rtrim(pendk_policy) end  as PolicyNumber 
    ,'InForce' as [Type]
    , (
        case
            when WPOLC_CONTRACT_CODE = 'A' then 'Active'
            when WPOLC_CONTRACT_CODE = 'T' then 'Terminated'     
            when WPOLC_CONTRACT_CODE = 'P' then 'Pending'  
            when WPOLC_CONTRACT_CODE = 'S' then 'Suspended'  
            when WPOLC_CONTRACT_CODE = 'H' then 'On Hold'
        end
    ) as [Status]
    ,  top 1  rtrim(nameRela.wname_individual_first) + ' '+ rtrim(nameRela.wname_individual_middle) + ' ' + rtrim(nameRela.wname_individual_last) as Customer

    inner join WRELA_TABL custRela on (custRela.WRELA_COMPANY_CODE = wpolc.WPOLC_COMPANY_CODE and custRela.WRELA_POLICY_NUMBER = wpolc.WPOLC_POLICY_NUMBER 
        and custRela.WRELA_RELATE_CODE in ('in', 'ji' , 'je')) order by  custRela.WRELA_RELATE_CODE

    inner join wname_tabl nameRela on (custRela.WRELA_COMPANY_CODE = nameRela.WNAME_COMPANY_CODE and custRela.WRELA_NAME_ID = nameRela.WNAME_NAME_ID )
    order by nameRela.WNAME_INDIVIDUAL_LAST

    inner join PENDKEY_TABL pk on (wrela.WRELA_COMPANY_CODE = pk.PendK_company and wrela.WRELA_POLICY_NUMBER = pk.PENDK_POLICY)

Answer 1

订单应该在查询中排在最后。基本格式为：

Select 
From
  inner join
where
order by

添加Top 1和Order By以选择具有多个连接的语句
