以下代码有什么问题,有些人可以帮我解决吗?
CREATE OR REPLACE TRIGGER TEST_TRI
AFTER INSERT
ON TEST1
FOR EACH ROW WHEN (NEW.COL2 >= '01-MAY-16')
BEGIN
IF INSERTING
THEN
MERGE INTO TEST_HIST HIST
USING TEST1 T1
ON (T1.NEW.COL1=HIST.COL2)
WHEN MATCHED THEN
UPDATE SET
HIST.COL5=NEW.COL5
WHEN NOT MATCHED
THEN
INSERT INTO
VALUES (:NEW.COL1,:NEW.COL2,:NEW.COL3,:NEW.COL4,:NEW.COL5);
END IF;
END;

错误: 错误(4,3):PL / SQL:忽略Sql stmt 错误(12,14):PL / SQL:ORA-00926:缺少关键字
感谢您提供的信息,我更改了以下代码并收到了新的错误。
CREATE OR REPLACE TRIGGER test_tri
after INSERT
ON test1
FOR EACH ROW WHEN (NEW.col5 >= '01-MAY-16')
DECLARE
PRAGMA AUTONOMOUS_TRANSACTION;
BEGIN
IF INSERTING
THEN
MERGE INTO test_hist hist
USING test1 t1
ON (t1.PACKAGE_ID=hist.PACKAGE_ID)
WHEN MATCHED THEN
UPDATE SET
hist.col5=t1.col5
WHEN NOT MATCHED
THEN
INSERT (col1,col2, col3, col4, col5)
VALUES (:NEW.col1,:NEW.col2,:NEW.col3,:NEW.col4,:NEW.col5);
END IF;
COMMIT;
END;

在test1表中插入记录时出现以下错误 ORA-30926:无法在源表中获得一组稳定的行
答案 0 :(得分:1)
我怀疑你的合并声明中的所有源数据都已混淆了。你只想考虑插入的行,对吗?
我认为你的触发器应该是这样的:
CREATE OR REPLACE TRIGGER test_tri
after INSERT
ON test1
FOR EACH ROW WHEN (NEW.col5 >= '01-MAY-16')
DECLARE
PRAGMA AUTONOMOUS_TRANSACTION;
BEGIN
IF INSERTING
THEN
MERGE INTO test_hist hist
USING (select :new.package_id, :new.col1, :new.col2, :new.col3, :new.col4, :new.col5
from dual) t1
ON (t1.PACKAGE_ID=hist.PACKAGE_ID)
WHEN MATCHED THEN
UPDATE SET hist.col5=t1.col5
WHEN NOT MATCHED THEN
INSERT (col1, col2, col3, col4, col5)
VALUES (t1.col1, t1.col2, t1.col3, t1.col4, t1.col5);
END IF;
COMMIT;
END;
/
N.B。如果:new.col5是日期列,则更改:
FOR EACH ROW WHEN (NEW.col5 >= '01-MAY-16')
到
FOR EACH ROW WHEN (NEW.col5 >= to_date('01/05/2016', 'dd/mm/yyyy'))
年有4位数(我猜你的意思是2016年,而不是1916年!)。
