Description

PDO::cubrid_schema(int $schema_type, [string $table_name], [string $col_name]): array

This function is used to get the requested schema information from database. You have to designate table_name, if you want to get information on certain table, col_name, if you want to get information on certain column (can be used only with PDO::CUBRID_SCH_COL_PRIVILEGE).

The result of this function is returned as a two-dimensional array (column (associative array) * row (numeric array)). The following tables shows types of schema and the column structure of the result array to be returned based on the schema type.

Examples

A PDO::cubrid_schema() example

This example shows how to get primary key and foreign keys of table game.

php

<?php
$pk_list = $dbh->cubrid_schema(PDO::CUBRID_SCH_PRIMARY_KEY, "game");
print_r($pk_list);

$fk_list = $dbh->cubrid_schema(PDO::CUBRID_SCH_IMPORTED_KEYS, "game");
print_r($fk_list);
?>

The above example will output:
