예제
SELECT
// 테이블생성
CREATE TABLE `test_table` ( `regdate` INT NOT NULL ) TYPE = MYISAM ;
// 데이타 삽입
INSERT INTO `test_table` ( `regdate` ) VALUES ('1220799600 ');
INSERT INTO `test_table` ( `regdate` ) VALUES (unix_timestamp());
CREATE TABLE `test_table` ( `regdate` INT NOT NULL ) TYPE = MYISAM ;
// 데이타 삽입
INSERT INTO `test_table` ( `regdate` ) VALUES ('1220799600 ');
INSERT INTO `test_table` ( `regdate` ) VALUES (unix_timestamp());
SELECT FROM_UNIXTIME(unix_timestamp);
SELECT FROM_UNIXTIME(unix_timestamp, format);
SELECT FROM_UNIXTIME(unix_timestamp, format);
