ORACLE SQL-在WHERE子句中使用GROUP BY無效標識符

Question

我在ORACLE SQL中有一個查詢，只有當debet_amount或者credit_amount的SUM大於或等於1000時，我才需要返回結果v_no。

電流誤差

ORA-00904: "g"."COMPANY": invalid identifier 
00904. 00000 - "%s: invalid identifier" 

當前查詢

SELECT DISTINCT 
g.company, 
g.v_type, 
g.v_no, 
g.v_date, 
g.a_year, 
g.a_period, 
g.entry_date, 
g.correction, 
CASE WHEN g.mcompany IS NULL THEN 'FALSE' ELSE g.mcompany END AS mcompany, 
g.debet_amount, 
g.credit_amount, 
g.amount, 
v.userid 
FROM genrow g, 
(SELECT v_no, SUM(debet_amount) AS debcomp FROM genrow GROUP BY v_no) subdeb, 
(SELECT v_no, SUM(credit_amount) AS credcomp FROM genrow GROUP BY v_no) subcred 
INNER JOIN genv v ON g.v_no = v.v_no AND g.company = v.company 
WHERE g.v_no = subdeb.v_no 
AND g.v_no = subcred.v_no 
AND (subdeb.debcomp >= 1000 or subcred.credcomp >= 1000) 
AND g.v_type IN ('M','Q','E') 

實施例的預期輸出

company v_type v_no v_date   a_year a_period entry_date correction mcompnay debet_amount credit_amount amount userid 
02  EXT  2000 25-JAN-14  2014 1   28-JAN-14 N   FALSE  600        600  USER13 
02  EXT  2000 25-JAN-14  2014 1   28-JAN-14 N   FALSE  200        200  USER16 
02  EXT  2000 25-JAN-14  2014 1   28-JAN-14 N   FALSE  300        300  USER12 
02  EXT  4000 25-JAN-14  2014 1   28-JAN-14 N   FALSE      500    500  USER19 
02  M  4000 29-MAR-14  2014 3   07-APR-14 N   FALSE      200    200  USER12 
02  EXT  4000 25-JAN-14  2014 1   28-JAN-14 N   FALSE      120    120  USER18 
02  EXT  4000 25-JAN-14  2014 1   28-JAN-14 N   FALSE      700    700  USER14 
02  EXT  6000 25-JAN-14  2014 1   28-JAN-14 N   FALSE  1100       1100 USER19 

Answer 1

的問題在於你在混合不能正確解析的隱式和顯式連接。

這應該工作：

SELECT DISTINCT 
    g.company, 
    g.v_type, 
    g.v_no, 
    g.v_date, 
    g.a_year, 
    g.a_period, 
    g.entry_date, 
    g.correction, 
    CASE WHEN g.mcompany IS NULL THEN 'FALSE' ELSE g.mcompany END AS mcompany, 
    g.debet_amount, 
    g.credit_amount, 
    g.amount, 
    v.userid 
FROM genrow g 
INNER JOIN (SELECT v_no, SUM(debet_amount) AS debcomp FROM genrow GROUP BY v_no) subdeb ON g.v_no = subdeb.v_no 
INNER JOIN (SELECT v_no, SUM(credit_amount) AS credcomp FROM genrow GROUP BY v_no) subcred ON g.v_no = subcred.v_no 
INNER JOIN genv v ON g.v_no = v.v_no AND g.company = v.company 
WHERE (subdeb.debcomp >= 1000 or subcred.credcomp >= 1000) 
AND g.v_type IN ('M','Q','E');
