sql for 循环查询到普通查询

Question

我有一个 for 循环查询，我试图在不循环的情况下更改它，并尝试在不循环的情况下验证一条记录。

所以，我正在寻找没有循环的正常查询。

<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普通查询。

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

      )
