C#程序实现将MySQL的存储过程转换成Oracle的存储过程
作者：weixin_30777913
文章介绍了如何使用C#控制台应用,将MySQL自增ID和批量插入语句转换为Oracle兼容的SEQUENCE、触发器和INSERTALL语法,实现存储过程自动适配,提升数据库迁移效率,需要的朋友可以参考下
技术栈：
- .NET Core 3.1+ 或 .NET 5/6/7/8 控制台应用
- 使用
System,System.Text.RegularExpressions,System.Text,System.Text.Json,System.Collections.Generic
Program.cs（完整代码）

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
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;

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;
