Question

SQL＃1就像我期望的那样工作。但是，我需要将3个字段（account，journal_id和journal_date）添加到另一个表的结果中.SQL＃2将结果中需要的3个字段返回给SQL＃1。它还返回asset_id字段，因为SQL的结果＃2必须与SQL＃1中的asset_ID字段相关。

我想知道SQL＃1中的子查询是否会返回3个字段。我是sql的新手，并且不知道在SQL＃1中从哪个子查询开始。任何有关此问题的帮助将不胜感激。谢谢。

您不需要子查询，只需加入附加表格。

SELECT 
    pa.BUSINESS_UNIT, 
    pa.DESCR,
    pdr.DEPTID, 
    pdr.ASSET_ID, 
    pdr.ACCOUNT_AD, 
    pdr.BOOK,

    MAX(CASE WHEN (pdr.FISCAL_YEAR =2014 AND pdr.ACCOUNTING_PERIOD =11) THEN  pdr.DEPR END) as CURRENT_AMT,
    MAX(CASE WHEN (pdr.FISCAL_YEAR =2104 AND pdr.ACCOUNTING_PERIOD =10) THEN pdr.DEPR  END) as PRIOR_AMT,

    pdl.journal_id,
    pdl.journal_date

FROM PS_ASSET pa

INNER JOIN PS_DEPR_RPT pdr 
    ON pa.ASSET_ID = pdr.ASSET_ID
    AND pa.BUSINESS_UNIT = pdr.BUSINESS_UNIT

LEFT JOIN ps_dist_ln pdl
    ON pdl.ASSET_ID = pdr.ASSET_ID
    AND pdl.book = pdr.book
    AND pdl.fiscal_year = pdr.fiscal_year
    AND pdl.accounting_period = pdr.accounting_period

WHERE 
    pa.BUSINESS_UNIT=A0465
    AND pdr.BOOK='PERFORM'
    AND ((pdr.FISCAL_YEAR=2014 AND pdr.ACCOUNTING_PERIOD=11) 
        OR (pdr.FISCAL_YEAR=2014 AND pdr.ACCOUNTING_PERIOD=10))
    and pdl.business_unit = 'A0465'
    and pdl.distribution_type = 'DE'

group by
    pa.business_unit,
    pa.descr,
    pdr.deptid,
    pdr.asset_id,
    pdr.account_ad,
    pdr.book

order by
    pdr.asset_id
