PHP 针对人大金仓KingbaseES自动生成数据字典

针对国产数据库 人大金仓KingbaseES  其实php 连接采用pdo方式

必须：需要去人大数据金仓官方网站 下载对应版本的pdo_kdb 扩展驱动

其连接方法与pgsql 数据库连接方法大致相同    不解释  直接上代码：

setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
} catch (PDOException $e) {
    die("连接失败: " . $e->getMessage());
}

$result = $conn->query("SELECT table_name FROM information_schema.tables WHERE table_schema = 'public'");
$tables = $result->fetchAll(PDO::FETCH_ASSOC);

$html = '';

$html .= '';
$html .= '';

foreach ($tables as $k => $v) {
    $sort = $k + 1;
    $tableName = $v['table_name'];

    // Get table comment
    $tableComment = $conn->query("SELECT obj_description('public.{$tableName}'::regclass, 'pg_class') AS table_comment")->fetchColumn();

    $html .= '';
    $html .= '';
    $html .= '';
    $html .= '';
    $html .= '';
}
$html .= '

$html .= "

foreach ($tables as $v) {
    $tableName = $v['table_name'];

    $fields = $conn->query("
