feature introduction

1. 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)
2. 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.
3. 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 ()

    created_date timestamp without time zone DEFAULT now ()
