MySQL自增ID适配：自动生成Oracle SEQUENCE与触发器

核心逻辑

自增表识别：通过两种场景判断含自增ID的表：
1. CREATE TABLE 中含 AUTO_INCREMENT 关键字（如 id INT AUTO_INCREMENT ）；
2. INSERT 语句字段不含 id （默认 id 为自增字段，如 INSERT INTO users(name) VALUES(‘a’) ）。
SEQUENCE生成：按 seq_表名_id 规范生成序列（如 seq_users_id ），默认起始值1、步长1，配置 NOCACHE NOCYCLE 避免缓存浪费。
触发器自动关联：生成 trg_表名_id 触发器，在 INSERT 时自动为 id 字段赋值 SEQUENCE.NEXTVAL ，完全模拟MySQL自增行为。

示例转换

MySQL自增表创建：

CREATE TABLE users (
  id INT AUTO_INCREMENT PRIMARY KEY,
  name VARCHAR(50)
);

生成Oracle代码：

-- SEQUENCE定义（适配MySQL自增ID）
CREATE SEQUENCE seq_users_id
  START WITH 1
  INjavascriptCREMENT BY 1
  NOCACHE NOCYCLE;
CREATE OR REPLACE TRIGGER trg_users_id
  BEFORE INSERT ON users
  FOR EACH ROW
BEGIN
  IF :NEW.id IS NULL THEN
    SELECT seq_users_id.NEXTVAL INTO :NEW.id FROM DUAL;
  END IF;
END;
/

MySQL批量INSERT优化：转换为Oracle INSERT ALL语法

核心逻辑

批量INSERT识别：提取MySQL中 INSERT INTO … VALUES(…),(…) 格式的批量语句（如 VALUES((1,‘a’),(2,‘b’)) ）。
语法转换规则：
1. 拆分行值：将 (1,‘a’),(2,‘b’) 拆分为 (1,‘a’) 和 (2,‘b’) ；
2. 自增表适配：若表含自增ID，自动在字段列表添加 id ，值列表添加 SEQUENCE.NEXTVAL ；
3. 生成 INSERT ALL ：通过 INSERT ALL INTO 表名(字段) VALUES(值) SELECT 1 FROM DUAL 实现批量插入（Oracle批量插入必须以 SELECT 1 FROM DUAL 结尾）。

示例转换

MySQL批量INSERT：

INSERT INTO users(name) VALUES('张三'),('李四'),('王五');

生成Oracle代码：

-- 批量插入（转换为Oracle INSERT ALL）
INSERT ALL
  INTO users (id, name) VALUES (seq_users_id.NEXTVAL, '张三')
  INTO users (id, name) VALUES (seq_users_id.NEXTVAL, '李四')
  INTO users (id, name) VALUES (seq_users_id.NEXTVAL, '王五')
SELECT 1 FROM DUAL; -- 必须添加SELECT 1 FROM DUAL

完整运行效果示例（含自增+批量INSERT）

输入MySQL存储过程：

CREATE PROCEDURE batch_add_users(IN dept_id INT)
BEGIN
  -- 批量插入3个用户
  INSERT INTO users(name, dept_id) VALUES
    ('张三', dept_id),
    ('李四', dept_id),
    ('王五', dept_id);
  
  -- 插入自增表（省略id）
  INSERT INTO logs(content) VALUES('批量添加用户');
  
  COMMIT;
END;

生成Oracle代码（关键部分）：

-- 1. SEQUENCE定义（适配MySQL自增ID）
CREATE SEQUENCE seq_users_id
  START WITH 1
  INCREMENT BY 1
  NOCACHE NOCYCLE;
CREATE OR REPLACE TRIGGER trg_users_id
  BEFORE INSERT ON users
  FOR EACH ROW
BEGIN
  IF :NEW.id IS NULL THEN
    SELECT seq_users_id.NEXTVAL INTO :NEW.id FROM DUAL;
  END IF;
END;
/

CREATE SEQUENCE seq_logs_id
  START WITH 1
  INCREMENT BY 1
  NOCACHE NOCYCLE;
CREATE OR REPLACE TRIGGER trg_logs_id
  BEFORE INSERT ON logs
  FOR EACH ROW
BEGIN
  IF :NEW.id IS NULL THEN
    SELECT seq_logs_id.NEXTVAL INTO :NEW.id FROM DUAL;
  END IF;
END;
/

-- 3. 存储过程 batch_add_users
CREATE OR REPLACE PROCEDURE batch_add_users(
       IN dept_id NUMBER(10)
)
IS
BEGIN

  -- 批量插入（转换为Oracle INSERT ALL）
  INSERT ALL
    INTO users (id, name, dept_id) VALUES (seq_users_id.NEXTVAL, '张三', dept_id)
    INTO users (id, name, dept_id) VALUES (seq_users_id.NEXTVAL, '李四', dept_id)
    INTO users (id, name, dept_id) VALUES (seq_users_id.NEXTVAL, '王五', dept_id)
  SELECT 1 FROM DUAL; -- 必须添加SELECT 1 FROM DUAL

  -- 普通业务逻辑
  INSERT INTO logs (id, content) VALUES (seq_logs_id.NEXTVAL, '批量添加用户');

  COMMIT;

  -- 异常处理（含游标清理）
  EXCEPTION
    WHEN OTHERS THEN
      DBMS_OUTPUT.PUT_LINE('异常：' || SQLERRM || '（行号：' || SQLCODE || '）');
END;
/
