pg_last_notice
Returns the last notice message from PostgreSQL server
(PHP 4 >= 4.0.6, PHP 5)
string pg_last_notice ( resource connection )
pg_last_notice() returns the last notice
message from the PostgreSQL server on the specified
connection. The PostgreSQL server sends notice
messages in several cases, for instance when creating a SERIAL
column in a table.
With pg_last_notice(), you can avoid issuing useless queries by checking whether or not the notice is related to your transaction.
Notice message tracking can be set to optional by setting 1 for
pgsql.ignore_notice in php.ini.
Notice message logging can be set to optional by setting 0 for
pgsql.log_notice in php.ini.
Unless pgsql.ignore_notice is set
to 0, notice message cannot be logged.
ChangeLog
| Version | Description |
|---|---|
| 4.3.0 | This function is now fully implemented. Earlier versions ignores database connection parameter. |
| 4.3.0 |
The pgsql.ignore_notice and
pgsql.log_notice php.ini directives were added.
|
| 4.0.6 | PHP 4.0.6 has problem with notice message handling. Use of the PostgreSQL module with PHP 4.0.6 is not recommended even if you are not using pg_last_notice(). |
Examples
Example 1941. pg_last_error() example
<?php
$pgsql_conn = pg_connect("dbname=mark host=localhost");
$res = pg_query("CREATE TABLE test (id SERIAL)");
$notice = pg_last_notice($pgsql_conn);
echo $notice;
?>The above example will output:
CREATE TABLE will create implicit sequence "test_id_seq" for "serial" column "test.id"
