pg_last_error
Popis
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.
Poznámka: This function used to be called pg_errormessage().
