請告訴我如何在處理當前表時參考該列。我需要對已經計算過的欄位進行計算，通過化名參考表欄位無濟于事，也許我錯過了其他東西，但如果有人向我指出我的愚蠢，我會很高興。我在一個簡單的地方看不到解決方案:(
非常感謝！
問題出在這個地方PLS-00225: subprogram or cursor 'F' reference is out of scope:

uj5u.com熱心網友回復：
這是f：
into dma.dm_f101_round_f f
^
here it is
f.balance_in_rub是這樣的：
-- RUB balance
sum( case
when cur.currency_code in ('643', '810')
then b.balance_out
else 0
end
) as balance_in_rub,
--------------
here it is
您不能僅通過命名來參考正在插入的列；在這方面是未知的。如果你想執行一些計算，你必須用“源”本身來做，即
then f.balance_in_rub - f.turn_cre_rub f.turn_deb_rub
會成為
then
sum(case
when cur.currency_code in ('643', '810')
then b.balance_out
else 0
end
) -
sum(case
when cur.currency_code in ('643', '810')
then at.credit_amount_rub
else 0
end
)
sum(case
when cur.currency_code in ('643', '810')
then at.debet_amount_rub
else 0
end
)
即你會重用所有的代碼。不太漂亮，恐怕。
另一種選擇是先做insert，update然后再做
update dm_f101_round_f f set
f.balance_out_rub = f.balance_in_rub - f.turn_cre_rub f.turn_deb_rub
where ...
