A
MySQL offers a number of formats for you to use to enter date and time literals:
- ANSI standard format: "YYYY-MM-DD HH:MM:SS".
- Non-standard limiters. Like: "YYYY/MM/DD HH^MM^SS" or "YYYY.MM.DD HH-MM-SS".
- No limiters. Like: "YYYYMMDD" for a date or "HHMMSS" for a time.
- Decimal numbers. Like: 8 digits dddddddd for a date or 6 digits dddddd for a time.
The tutorial exercise below gives you some good examples:
SELECT DATE('1997-01-31') FROM DUAL;
1997-01-31
SELECT DATE('1997-01-31 09:26:50') FROM DUAL;
1997-01-31
SELECT TIME('1997-01-31 09:26:50') FROM DUAL;
09:26:50
SELECT DATE('1997/01/31 09^26^50') FROM DUAL;
1997-01-31
SELECT TIME('1997/01/31 09^26^50') FROM DUAL;
09:26:50
SELECT DATE('19970131') FROM DUAL;
1997-01-31
SELECT TIME('092650') FROM DUAL;
09:26:50
SELECT DATE(19970131) FROM DUAL; -- Crazy format
1997-01-31
SELECT TIME(092650) FROM DUAL; -- Crazy format
09:26:50
