# INSERT IGNORE

## Ignoring Errors

Normally [INSERT](https://mariadb.com/docs/server/reference/sql-statements/data-manipulation/inserting-loading-data/insert) stops and rolls back when it encounters an error.

By using the [IGNORE](https://mariadb.com/docs/server/reference/sql-statements/data-manipulation/inserting-loading-data/ignore) keyword all errors are converted to warnings, which will not stop inserts of additional rows.

Invalid values are changed to the closest valid value and inserted, with a warning produced.

The IGNORE and DELAYED options are ignored when you use [ON DUPLICATE KEY UPDATE](https://mariadb.com/docs/server/reference/sql-statements/data-manipulation/inserting-loading-data/insert-on-duplicate-key-update).

{% tabs %}
{% tab title="Current" %}
Warnings are issued for duplicate key errors when using `IGNORE`. You can get the old behavior if you set [OLD\_MODE](https://mariadb.com/docs/server/server-management/variables-and-modes/old_mode) to `NO_DUP_KEY_WARNINGS_WITH_IGNORE`.
{% endtab %}

{% tab title="< 5.5.28" %}
No warnings are issued for duplicate key errors when using `IGNORE`.
{% endtab %}
{% endtabs %}

See [IGNORE](https://mariadb.com/docs/server/reference/sql-statements/data-manipulation/inserting-loading-data/ignore) for a full description of effects.

## Examples

```sql
CREATE TABLE t1 (x INT UNIQUE);

INSERT INTO t1 VALUES(1),(2);

INSERT INTO t1 VALUES(2),(3);
ERROR 1062 (23000): Duplicate entry '2' for key 'x'
SELECT * FROM t1;
+------+
| x    |
+------+
|    1 |
|    2 |
+------+

INSERT IGNORE INTO t1 VALUES(2),(3);
Query OK, 1 row affected, 1 warning (0.04 sec)

SHOW WARNINGS;
+---------+------+---------------------------------+
| Level   | Code | Message                         |
+---------+------+---------------------------------+
| Warning | 1062 | Duplicate entry '2' for key 'x' |
+---------+------+---------------------------------+

SELECT * FROM t1;
+------+
| x    |
+------+
|    1 |
|    2 |
|    3 |
+------+
```

Converting values:

```sql
CREATE OR REPLACE TABLE t2(id INT, t VARCHAR(2) NOT NULL, n INT NOT NULL);

INSERT INTO t2(id) VALUES (1),(2);
ERROR 1364 (HY000): Field 't' doesn't have a default value

INSERT IGNORE INTO t2(id) VALUES (1),(2);
Query OK, 2 rows affected, 2 warnings (0.026 sec)
Records: 2  Duplicates: 0  Warnings: 2

SHOW WARNINGS;
+---------+------+----------------------------------------+
| Level   | Code | Message                                |
+---------+------+----------------------------------------+
| Warning | 1364 | Field 't' doesn't have a default value |
| Warning | 1364 | Field 'n' doesn't have a default value |
+---------+------+----------------------------------------+

SELECT * FROM t2;
+------+---+---+
| id   | t | n |
+------+---+---+
|    1 |   | 0 |
|    2 |   | 0 |
+------+---+---+
```

See [INSERT ON DUPLICATE KEY UPDATE](https://mariadb.com/docs/server/reference/sql-statements/data-manipulation/inserting-loading-data/insert-on-duplicate-key-update) for further examples using that syntax.
