功能介紹

1.支持多種資料庫的建表 sql轉gorm, 其中包含(pg、oracle、mysql)等資料庫; 建表語句, 建表語句, 建表語句(重要的說3遍)
2.在轉換 sql 的時候, 需要確認下是否需要切換處理類型, 暫時支持3種處理方式(normal, postgresql, oracle), 默認: normal.
3.支持自定義過濾不需要的欄位, 多個欄位通過 , 隔開
說明: 不能在 sql 中包含注釋內容(即: -- xxx 或 # xxx); 由於此工具是通過 ; 來分割語句處理.所以 normal 狀態下可以同時處理多個建表語句; postgresql 和 oracle 由於需要解析注釋, 只支持單個建表語句.

示例

mysql 建表語句

CREATE TABLE if not exists user (
    id int NOT NULL AUTO_INCREMENT,
    name varchar(10) NOT NULL COMMENT '姓名',
    gender tinyint NOT NULL DEFAULT 0 COMMENT '性別 0-未知 1-男 2-女',
    age int NOT NULL COMMENT '年齡',
    created_date datetime DEFAULT CURRENT_TIMESP,
    updated_date datetime DEFAULT CURRENT_TIMESP ON UPDATE CURRENT_TIMESP,
    PRIMARY KEY (id)
);

    updated_date: Mapped[datetime.datetime] = mapped_column(DateTime, server_default=func.now())

pgsql 建表語句

CREATE TABLE if not exists user (
    id character varying(32) NOT NULL DEFAULT sys_guid(),
    name character varying(10) NOT NULL,
    gender tinyint NOT NULL,
    age tinyint NOT NULL,
    created_date timesp without time zone DEFAULT now(),
    updated_date timesp without time zone DEFAULT now(),
    CONSTRAINT user_pkey PRIMARY KEY (id)
);
COMMENT ON TABLE user IS '用戶表';
COMMENT ON COLUMN user.id IS '主鍵';
COMMENT ON COLUMN user.name IS '姓名';
COMMENT ON COLUMN user.gender IS '性別 0-未知 1-男 2-女';
COMMENT ON COLUMN user.age IS '年齡';
COMMENT ON COLUMN user.created_date IS '創建時間';
COMMENT ON COLUMN user.updated_date IS '更新時間';
