pg_update — 更新表
說明
mixed pg_update ( resource$connection
, string $table_name
, array $data
, array $condition
[, int $options = PGSQL_DML_EXEC
] )
pg_update() 用 condition 作為條件查詢數據庫，用 data 中的數據更新符合條件的記錄。如果指定了 options，則 pg_convert() 會按照指定選項作用到 data 上。
Warning此函數是實驗性的。此函數的表象，包括名稱及其相關文檔都可能在未來的 PHP 發布版本中未通知就被修改。使用本函數風險自擔 。
參數
connection
PostgreSQL database connection resource.
table_name
Name of the table into which to update rows.
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.
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.
options
Any number of PGSQL_CONV_OPTS,
PGSQL_DML_NO_CONV,
PGSQL_DML_EXEC or
PGSQL_DML_STRING combined. If PGSQL_DML_STRING is part of the
options then query string is returned.
返回值
成功時返回 TRUE， 或者在失敗時返回 FALSE。 Returns string if PGSQL_DML_STRING is passed
via options.
范例
Example #1 pg_update() 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: $resn";
} else {
echo "User must have sent wrong inputsn";
}
?>
