我需要通过 SELECT 语句检查表中是否存在记录。如果记录存在,则进行更新,否则在表上创建记录。我正在尝试,但遇到 PLS-00103
错误。
这些是我在 DBVisaulzier 中运行代码时遇到的错误:
18:00:09 [DECLARE - 0 row(s), 0.000 secs] [Error Code: 6550, SQL State: 65000] ORA-06550: line 2, column 12:

... 6 statement(s) executed, 0 row(s) affected, exec/fetch time: 0.000/0.000 sec [0 successful, 0 warnings, 6 errors]
以下是我的代码:
DECLARE a NUMBER;
BEGIN
SELECT 1
INTO a
FROM FREC_EMAIL t
WHERE t.FranchiseNo = '208254846'
AND t.ReportID = 1
AND t.id = 165;
IF a=1 THEN
UPDATE FREC_EMAIL
SET email = 'blah@foo.com'
WHERE FranchiseNo = '208254846'
AND ReportID = 1
AND ID = 165;
ELSE
INSERT INTO FREC_EMAIL
(FranchiseNo, Email, ReportID)
VALUES
('208254846', 'blah@foo.com', 1);
END IF;
END;
最佳答案
我们应该尽可能使用 SQL,除非绝对必要,否则避免使用 Pl/SQL。 SQL 语句执行得更快,它们通常需要更少的输入,并且更容易正确。
自 9i 以来,Oracle 提供了 MERGE,即执行“upsert”语句的单个 SQL 语句。
MERGE INTO frec_email t
USING (SELECT 'blah@foo.com' as email
, '208254846' as FranchiseNo
, 1 as ReportID
, 165 as ID
FROM dual ) s
ON (s.ID = t.ID)
WHEN MATCHED THEN
UPDATE SET t.email = s.email
WHEN NOT MATCHED THEN
INSERT (t.FranchiseNo, t.Email, t.ReportID)
VALUES (s.FranchiseNo, s.Email, s.ReportID)
