使用 oracle 11g 数据库的 sql 文件中的触发器不起作用

Question

我对 Oracle 11g 和 Liquibase 有疑问。我一直在寻找一个好的答案。在我的 db-changelog.xml 中，我指向一个有触发器的 sql 文件。这根本不起作用。我已经用 /\; 测试了您上面所说的内容和一个和几个触发器。我得到一个带有 / 的 ORA-00911。 Ora-00900 带有 END “触发器名称”；在 sql 中。

        CREATE OR REPLACE TRIGGER ADRESSE_ID_TR 
        BEFORE INSERT ON ADRESSE 
        FOR EACH ROW 
        WHEN (new.ID IS NULL) BEGIN 
        SELECT adresse_seq.NEXTVAL 
        INTO   :new.ID 
        FROM   dual; 
        END ADRESSE_ID_TR;\

我的解决方法是在 db-changelog.xml 中添加一个 in。我不喜欢它，因为 db-changelog.xml 会非常大，我希望它在 .sql 文件中而不是在 db-changelog.xml 中。当我们开发 Java 代码时，我们将对数据库进行大量更改。更改应该在更大的 sql 文件中。还是我错了？

另一个问题是，当我使用 Oracle SQL Developer、Toad、SQL Plus 等工具生成 DDL 时，它们不起作用。当我使用工具执行 DDL 时，它们就起作用了。很多 sql 不起作用，因为 Liquibase 可能不支持 SQL。我花了很多时间用 Eclipse 测试我的 SQL 和 Liquibase 来修复 SQL。有什么提示或者你会解决这个问题吗？

Answer 1

这不是有效的触发器语法；下面是：

CREATE OR REPLACE TRIGGER ADRESSE_ID_TR          
BEFORE INSERT ON ADRESSE          
FOR EACH ROW          
BEGIN
  IF (:new.ID IS NULL)  THEN
    SELECT adresse_seq.NEXTVAL          
      INTO   :new.ID          
      FROM   dual;          
  END IF;
END ADRESSE_ID_TR;
/ 

Answer 2

由于触发代码的更改，我确实收到了错误：

我的sql是这样的： --liquibase 格式化的sql

--changeset martin.raczkowski:2011-11-24-SP2_2_5.sql
DROP TABLE ADRESSE cascade constraints;

CREATE TABLE ADRESSE 
    (   
ID NUMBER, 
PERSON_ID NUMBER, 
GATEADRESSE1 VARCHAR2(256 BYTE), 
GATEADRESSE2 VARCHAR2(256 BYTE), 
POSTNUMMER VARCHAR2(20 BYTE), 
POSTSTED VARCHAR2(256 BYTE), 
ADRESSETYPE VARCHAR2(20 BYTE), 
TIDENDRET DATE, 
SAKSBEHANDLER VARCHAR2(20 BYTE), 
BYDEL VARCHAR2(20 BYTE), 
ENHET VARCHAR2(20 BYTE),
CONSTRAINT ADRESSE_PK PRIMARY KEY 
    (
    ID 
    )
   ENABLE 
   );

CREATE OR REPLACE TRIGGER ADRESSE_ID_TR          
BEFORE INSERT ON ADRESSE          
FOR EACH ROW          
BEGIN
F (new.ID IS NULL)  THEN
SELECT adresse_seq.NEXTVAL          
FROM   dual;          
END IF;
END ADRESSE_ID_TR;

我的 db-changelog.xml：（.xml 文件中的触发器工作正常，而我放在 .sql 中的触发器不起作用）
