如何将CONSTRAINT从PostgreSQL转换为MySQL?
CREATE TABLE language_history (
pk int NOT NULL AUTO_INCREMENT PRIMARY KEY,
latitude double precision,
longitude double precision,
version int NOT NULL,
CONSTRAINT language_history_latitude_check CHECK (((((-90))::double precision <= latitude) AND (latitude <= (90)::double precision))),
CONSTRAINT language_history_longitude_check CHECK (((((-180))::double precision <= longitude) AND (longitude <= (180)::double precision)))
);
