在Oracle中使用两个表更新SQL

Question

我有这样的SQL

UPDATE A
SET A.TEMSILCI_KOD = 4
FROM S_MUSTERI A, S_TEKLIF B
WHERE A.TEMSILCI_KOD = 9
AND B.BAYI_KOD = 17
AND A.HESAP_NO = B.HESAP_NO

但我得到这样的错误

Error starting at line 8 in command:
UPDATE A
SET A.TEMSILCI_KOD = 4
FROM S_MUSTERI A, S_TEKLIF B
WHERE A.TEMSILCI_KOD = 9
AND B.BAYI_KOD = 17
AND A.HESAP_NO = B.HESAP_NO
Error at Command Line:9 Column:22
Error report:
SQL Error: ORA-00933: SQL command not properly ended
00933. 00000 -  "SQL command not properly ended"
*Cause:    
*Action:

在哪里ERROR？

Answer 1

也许是这样的

UPDATE S_MUSTERI
SET TEMSILCI_KOD = 4
WHERE TEMSILCI_KOD = 9
AND EXISTS (SELECT 1 FROM S_TEKLIF B
WHERE S_MUSTERI.HESAP_NO = B.HESAP_NO
AND B.BAYI_KOD = 17)
