PG_UPDATE(3)PG_UPDATE(3)pg_update - Update tableSYNOPSIS
mixed pg_update (resource $connection, string $table_name, array $data, array $condition, [int $options = PGSQL_DML_EXEC])
DESCRIPTION pg_update(3) updates records that matches condition with data. If options is specified, pg_convert(3) is applied to data with specified
options.
PARAMETERS
o $connection
- PostgreSQL database connection resource.
o $table_name
- Name of the table into which to update rows.
o $data
- An array whose keys are field names in the table $table_name, and whose values are what matched rows are to be updated to.
o $condition
- An array whose keys are field names in the table $table_name, and whose values are the conditions that a row must meet to be
updated.
o $options
- Any number of PGSQL_CONV_FORCE_NULL, PGSQL_DML_NO_CONV, PGSQL_DML_ESCAPE, PGSQL_DML_EXEC, PGSQL_DML_ASYNC or PGSQL_DML_STRING
combined. If PGSQL_DML_STRING is part of the $options then query string is returned. When PGSQL_DML_NO_CONV or PGSQL_DML_ESCAPE is
set, it does not call pg_convert(3) internally.
RETURN VALUES
Returns TRUE on success or FALSE on failure. Returns string if PGSQL_DML_STRING is passed via $options.
EXAMPLES
Example #1
pg_update(3) example
<?php
$db = pg_connect('dbname=foo');
$data = array('field1'=>'AA', 'field2'=>'BB');
// This is safe, since $_POST is converted automatically
$res = pg_update($db, 'post_log', $_POST, $data);
if ($res) {
echo "Data is updated: $res
";
} else {
echo "User must have sent wrong inputs
";
}
?>
