這不是問題。問題以字符'？'結尾。我不知道你的意思是「將這兩個選擇列表相互添加」。 –

問題不明確。你可能想看看[mcve]來建立一個例子並澄清你的問題。事實上，我相信這個問題很快就會結束。 – Aleksej

我注意到兩件事：1）你的內部查詢可以只是一個帶有GROUP BY的查詢，2）你應該使用'JOIN'而不是SELECT ... FROM x，y WHERE ...在這些被修復之後，看看是否連接兩個表的正確連接並不清晰。 –

你內心的疑問可以直接寫成

select bld_comp_code name, count(*) value 
    from bld_comp_prep 
    where comp_code =: a_bld_user_comp 
    and nvl(status,'S')='S' 
    and nvl(delete_flag,'N') ='N' 
    and bld_comp_code IN ('WHB', 'RBC', 'FFP', 'PLC', 'CRY') 
    group by bld_comp_code

和

select prep.bld_comp_code name, count(*) value 
from bld_issue_dtl dtl, 
    bld_issue_hdr hdr, 
    bld_comp_prep prep 
where hdr.issue_code = dtl.issue_code 
    and hdr.comp_code = dtl.comp_code 
    and dtl.comp_bag_code = prep.comp_bag_code 
    and dtl.comp_code = prep.comp_code 
    and TO_DATE(hdr.issue_date,'DD-MON-YY') = TO_DATE(:P29_STOCK_DATE,'DD-MON-YY') 
    and prep.bld_comp_code IN ('WHB', 'RBC', 'FFP', 'PLC', 'CRY') 
group by prep.bld_comp_code

可與首選JOIN語法編寫添加這兩個選擇列表：

select prep.bld_comp_code name, count(*) value 
from bld_issue_dtl dtl 
INNER JOIN bld_issue_hdr hdr 
     ON hdr.issue_code = dtl.issue_code 
     and hdr.comp_code = dtl.comp_code 
INNER JOIN bld_comp_prep prep 
     ON dtl.comp_bag_code = prep.comp_bag_code 
     and dtl.comp_code = prep.comp_code 
where TO_DATE(hdr.issue_date,'DD-MON-YY') = TO_DATE(:P29_STOCK_DATE,'DD-MON-YY') 
    and prep.bld_comp_code IN ('WHB', 'RBC', 'FFP', 'PLC', 'CRY') 
group by prep.bld_comp_code

但是目前還不清楚你打算加入兩套或預期的結果。

@Aleksej良好的捕獲 - 忘記在別名之前添加列。 –
