LAST_QUERY_ID

Description

Returns the ID of a specified query in the current session. If no query is specified, the most recently-executed query is returned.

Syntax

LAST_QUERY_ID( [ <num> ] )

Arguments

num: Specifies the query to return, based on the position of the query (within the session).

Default: -1

Usage Notes

Positive numbers start with the first query executed in the session. For example:

  • LAST_QUERY_ID(1) returns the first query.

  • LAST_QUERY_ID(2) returns the second query.

  • LAST_QUERY_ID(6) returns the sixth query.

Negative numbers start with the most recently-executed query in the session. For example:

  • LAST_QUERY_ID(-1) returns the most recently-executed query (equivalent to LAST_QUERY_ID()).

  • LAST_QUERY_ID(-2) returns the second most recently-executed query.

Examples

```sql mysql> SELECT LAST_QUERY_ID(-1); +--------------------------------------+ | last_query_id(-1) | +--------------------------------------+ | af974680-b1b5-11ed-8eb9-5ad2460dea4f | +--------------------------------------+ 1 row in set (0.00 sec)

mysql> SELECT LAST_QUERY_ID(); +--------------------------------------+ | last_query_id() | +--------------------------------------+ | 550e4d44-b1b5-11ed-8eb9-5ad2460dea4f | +--------------------------------------+ 1 row in set (0.00 sec) ```
