ORA-32576: missing TYPE keyword ORACLE 报错 故障修复 远程处理
文档解释
ORA-32576: missing TYPE keyword
Cause: keyword TYPE is missing.
Action: Use TYPE keyword.
ORA-32576：缺少TYPE关键字
官方解释
更新会引发ORA-32576错误的原因是触发器定义缺少“TYPE”关键字，更新只能由表级触发器来响应，语法应该是：
CREATE [OR REPLACE] TRIGGER trigger_name
{BEFORE | AFTER | INSTEAD OF}
{INSERT [OR] | UPDATE [OR] | DELETE}
ON table_name
[REFERENCING OLD AS o NEW AS n]
[FOR EACH ROW]
WHEN (condition)
TYPE {ROW | STATEMENT}
[ORDER integer]
[ENABLE | DISABLE]
[FOLLOWS | PRECEDES another_trigger]
{CALL proc_name |
DECLARE
var_name datatype;
[BEGIN
executable_statements;
END; ]
}
常见案例
当您尝试创建表级触发器时，您可能会遇到以下错误（Oracle触发器）：
SQL> CREATE OR REPLACE TRIGGER trigger_name
2 BEFORE INSERT OR UPDATE
3 ON table_name
4 REFERENCING OLD AS o NEW AS n
5 FOR EACH ROW
6 WHEN (condition)
7 BEGIN
8 null;
9 END;
ERROR at line 6:
ORA-32576: missing TYPE keyword
一般处理方法及步骤
要解决这个错误，需要补充关键字“TYPE”到触发器定义中，语法应该是：
CREATE [OR REPLACE] TRIGGER trigger_name
{BEFORE | AFTER | INSTEAD OF}
{INSERT [OR] | UPDATE [OR] | DELETE}
ON table_name
[REFERENCING OLD AS o NEW AS n]
[FOR EACH ROW]
WHEN (condition)
TYPE {ROW | STATEMENT}
[ORDER integer]
[ENABLE | DISABLE]
[FOLLOWS | PRECEDES another_trigger]
{CALL proc_name |
DECLARE
var_name datatype;
[BEGIN
executable_statements;
END; ]
};
这里，TYPE紧跟WHEN指令之后，它指定触发器的类型，可为“ROW”（行触发器）或“STATEMENT”（SQL语句触发器）。因此，在上面的示例中，添加TYPE ROW（或TYPE STATEMENT）后就可以创建正确的触发器了。
