pg_last_error
Get the last error message string of a connection
Description
string pg_last_error
([ resource $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.
