This tool provides a solution for automatically converting multiple databases from SQL to Ent code, and supports major databases such as MySQL, PostgreSQL, and Oracle. This tool automatically parses annotations and accurately filters fields. It aims to simplify the generation process of Ent Model files, improve work efficiency, and help developers efficiently manage and maintain data models.
使用说明
feature introduction
- Support a variety of databases to build tables sql ent, including (pg, mysql) database; ** construct predicative sentence **, ** construct predicative sentence **, ** construct predicative sentence **(important say 3 times)
- When converting sql, you need to confirm whether you need to switch the processing type. Three processing methods (mysql, postgresql) are temporarily supported, and the default is mysql.
- Support custom filtering of unwanted fields, multiple fields separated by ,
note: comment content contained in the SQL(i.e.,-or# XXX XXX); Since this tool is available through ; to split statement processing.
example
mysql table statement
CREATE TABLE if not exists user (
id int NOT NULL AUTO_INCREMENT,
name varchar(10) NOT NULL COMMENT 'name ',
gender tinyint NOT NULL DEFAULT 0 COMMENT 'Gender 0 -unknown 1 -male 2 -female ',
age int NOT NULL COMMENT 'age ',
created_date datetime DEFAULT CURRENT_TIMESTAMP,
updated_date datetime DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
PRIMARY KEY (id)
);
