Syntax

YEAR(date)

Description

SQL_TSI_YEAR is a synonym for YEAR:

Examples

CREATE TABLE t1 (d DATETIME);
INSERT INTO t1 VALUES
    ("2007-01-30 21:31:07"),
    ("1983-10-15 06:42:51"),
    ("2011-04-21 12:34:56"),
    ("2011-10-30 06:31:41"),
    ("2011-01-30 14:03:25"),
    ("2004-10-07 11:19:34");

SELECT * FROM t1;
+---------------------+
| d                   |
+---------------------+
| 2007-01-30 21:31:07 |
| 1983-10-15 06:42:51 |
| 2011-04-21 12:34:56 |
| 2011-10-30 06:31:41 |
| 2011-01-30 14:03:25 |
| 2004-10-07 11:19:34 |
+---------------------+

SELECT * FROM t1 WHERE YEAR(d) = 2011;
+---------------------+
| d                   |
+---------------------+
| 2011-04-21 12:34:56 |
| 2011-10-30 06:31:41 |
| 2011-01-30 14:03:25 |
+---------------------+

SELECT YEAR('1987-01-01');
+--------------------+
| YEAR('1987-01-01') |
+--------------------+
|               1987 |

YEAR Format

CREATE TABLE year_format_example (
  description VARCHAR(30),
  example YEAR
);

INSERT INTO year_format_example VALUES
  ('4-digit numeric year', 1966),
  ('2-digit numeric year', 66),
  ('4-digit string year', '1966'),
  ('2-digit string year', '66');

The resulting output would look like this:

SELECT * FROM year_format_example;

+----------------------+---------+
| description          | example |
+----------------------+---------+
| 4-digit numeric year |    1966 |
| 2-digit numeric year |    2066 |
| 4-digit string year  |    1966 |
| 2-digit string year  |    2066 |
+----------------------+---------+

YEAR Range

CREATE TABLE year_range_example (
  description VARCHAR(30),
  example YEAR
);

INSERT INTO year_range_example VALUES
  ('minimum', 1901),
  ('maximum', 2155),
  ('below minimum', 1900),
  ('above maximum', 2156);

If SQL_MODE is strict (the default), the example above generates the following error and no values are inserted:

ERROR 1264 (22003): Out of range value for column 'example' at row 3

If SQL_MODE is not strict, the example above generates a warning and (possibly modified) values are inserted:

Warning (sql 1264): Out of range value for column 'example' at row 3
Warning (sql 1264): Out of range value for column 'example' at row 4
The resulting data would look like this:

SELECT * FROM year_range_example;

+---------------+---------+
| description   | example |
+---------------+---------+
| minimum       |    1901 |
| maximum       |    2155 |
| below minimum |    0000 |
| above maximum |    0000 |
+---------------+---------+

Zero YEAR

CREATE TABLE year_zero_example (
  description VARCHAR(30),
  example YEAR
);

INSERT INTO year_zero_example VALUES
  ('4-digit numeric zero', 0000),
  ('3-digit numeric zero', 000),
  ('2-digit numeric zero', 00),
  ('1-digit numeric zero', 0),
  ('4-digit string zero', '0000'),
  ('3-digit string zero', '000'),
  ('2-digit string zero', '00'),
  ('1-digit string zero', '0');

The resulting data would look like this:

SELECT * FROM year_zero_example;

+----------------------+---------+
| description          | example |
+----------------------+---------+
| 4-digit numeric zero |    0000 |
| 3-digit numeric zero |    0000 |
| 2-digit numeric zero |    0000 |
| 1-digit numeric zero |    0000 |
| 4-digit string zero  |    0000 |
| 3-digit string zero  |    2000 |
| 2-digit string zero  |    2000 |
| 1-digit string zero  |    2000 |
+----------------------+---------+
