pg_last_error

Get the last error message string of a connection

Description

string pg_last_error ([ resource $connection ] )

pg_last_error returns the last error message for a given connection.

Error messages may be overwritten by internal PostgreSQL (libpq) function calls. It may not return an appropriate error message if multiple errors occur inside a PostgreSQL module function.

Use pg_result_error, pg_result_error_field, pg_result_status and pg_connection_status for better error handling.

Note:

This function used to be called pg_errormessage.

Parameters

connection

PostgreSQL database connection resource. When connection is not present, the default connection is used. The default connection is the last connection made by pg_connect or pg_pconnect.

Return Values

A string containing the last error message on the given connection, or FALSE on error.

Examples

$res pg_query($dbconn"select * from doesnotexist");
  
  echo 
pg_last_error($dbconn);
?>
