feature introduction

1. Table creation sql to gorm 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)
);
