mysql_info -- Get information about the most recent query

Syntax

string mysql_info ( [resource link_identifier] )

Returns detailed information about the last query.

Parameters

link_identifier: The MySQL connection. If the link identifier is not specified, the last link opened by mysql_connect() is assumed. If no such link is found, it will try to create one as if mysql_connect() was called with no arguments. If by chance no connection is found or established, an E_WARNING level warning is generated.

Return Values

Returns information about the statement on success, or FALSE on failure. See the example below for which statements provide information, and what the returned value may look like. Statements that aren't listed will return FALSE

Examples

Example 1. Relevant MySQL Statements

Statements that return string values. The numbers are only for illustrating purpose; their values will correspond to the query.

INSERT INTO ... SELECT ...
String format: Records: 23 Duplicates: 0 Warnings: 0 
INSERT INTO ... VALUES (...),(...),(...)...
String format: Records: 37 Duplicates: 0 Warnings: 0 
LOAD DATA INFILE ...
String format: Records: 42 Deleted: 0 Skipped: 0 Warnings: 0 
ALTER TABLE
String format: Records: 60 Duplicates: 0 Warnings: 0 
UPDATE
String format: Rows matched: 65 Changed: 65 Warnings: 0

Notes

Note: mysql_info() returns a non-FALSE value for the INSERT ... VALUES statement only if multiple value lists are specified in the statement.
