This tool provides a solution for automatically converting multiple databases from SQL to Proto code, and supports major databases such as MySQL, PostgreSQL, and Oracle. This tool automatically parses annotations, accurately filters fields, and controls the injection position of annotations. It aims to simplify the generation process of Proto files, improve work efficiency, and help developers efficiently manage and maintain data models.

使用说明

feature introduction

Table creation sql to proto supporting multiple databases, including (pg, oracle, mysql) and other databases; table-building statements, table-building statements, table-building statements(important statements are said 3 times)

When converting sql, you need to confirm whether you need to switch the processing type. Three processing methods are temporarily supported (normal, postgresql, oracle). Default: normal.

Support custom filtering of unwanted fields. Multiple fields are separated by ,.
Note: cannot include comments in sql(that is, --xxx or # xxx), because this tool divides statement processing through ;. Therefore, multiple table creation statements can be processed at the same time in normal, postgresql and oracle only support a single table creation statement because they need to parse comments.

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)
);

After treatment

message UserInfo {
    int32 id = 1
    string name = 2; // name
    int32 gender = 3; // gender 0-unknown 1-male 2-female
    int32 age = 4; //Age
    string created_date = 5
    string updated_date = 6
}

pgsql table statement

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 timestamp without time zone DEFAULT now ()
    updated_date timestamp without time zone DEFAULT now ()
    CONSTRAINT user_pkey PRIMARY KEY (id)
);
COMMENT ON TABLE user IS 'user Table'
COMMENT ON COLUMN user.id IS 'primary key'
COMMENT ON COLUMN user.name IS 'name'
COMMENT ON COLUMN user.gender IS 'Sex 0-unknown 1-male 2-female'
COMMENT ON COLUMN user.age IS 'age'
COMMENT ON COLUMN user.created_date IS 'creation time'
COMMENT ON COLUMN user.updated_date IS 'update time'

After treatment

message UserInfo {
    int32 id = 1
    string name = 2; // name
    int32 gender = 3; // gender 0-unknown 1-male 2-female
    int32 age = 4; //Age
    string created_date = 5
    string updated_date = 6
}

oracle table statement

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 date default sysdate
Updated_date date default sysdate
CONSTRAINT user_pkey PRIMARY KEY (id)
);
COMMENT ON TABLE user IS 'user Table'
COMMENT ON COLUMN user.id IS 'primary key'

COMMENT ON COLUMN user.age IS 'age'
COMMENT ON COLUMN user.created_date IS 'creation time'
COMMENT ON COLUMN user.updated_date IS 'update time'

After treatment
