Question

我有一个for循环查询，我试图在不循环的情况下进行更改，并尝试对一条记录进行外循环验证。

所以，我正在寻找没有循环的普通查询。

<query name="validate2">
    <![CDATA[
    begin
        for rec in (
            select staging.profileId as sfId                    
            from staging_pricematch_adj staging
                left outer join client cl
                    on staging.profileId = cl.salesforce_Id
            where staging.rejectcode is null
                and cl.salesforce_Id is null
        ) loop
            update staging_pricematch_adj
            set rejectcode        = '002',
            rejectReason = 'INVALID_PROFILE_ID'
            where profileId = rec.sfId;             
        end loop;
    end;
    ]]>
</query>

我正在寻找没有循环条件的noraml查询。

Answer 1

简单地说，这将起作用：

      update staging_pricematch_adj
      set rejectcode        = '002',
      rejectReason = 'INVALID_PROFILE_ID'
      where profileId IN (

        select staging.profileId                    
        from staging_pricematch_adj staging
            left outer join client cl
                on staging.profileId = cl.salesforce_Id
        where staging.rejectcode is null
            and cl.salesforce_Id is null

      )

sql for循环查询到普通查询
