PDO::cubrid_schema — Get the requested schema information
Beschreibung
$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.

Beispiele
Beispiel #1 A PDO::cubrid_schema() example
This example shows how to get primary key and foreign keys of table game.
<?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);
?>
Das oben gezeigte Beispiel erzeugt folgende Ausgabe:
Result: Array ( [0] => Array ( [CLASS_NAME] => game [ATTR_NAME] => athlete_code [KEY_SEQ] => 3 [KEY_NAME] => pk_game_host_year_event_code_athlete_code ) [1] => Array ( [CLASS_NAME] => game [ATTR_NAME] => event_code [KEY_SEQ] => 2 [KEY_NAME] => pk_game_host_year_event_code_athlete_code ) [2] => Array ( [CLASS_NAME] => game [ATTR_NAME] => host_year [KEY_SEQ] => 1 [KEY_NAME] => pk_game_host_year_event_code_athlete_code ) ) Array ( [0] => Array ( [PKTABLE_NAME] => athlete [PKCOLUMN_NAME] => code [FKTABLE_NAME] => game [FKCOLUMN_NAME] => athlete_code [KEY_SEQ] => 1 [UPDATE_RULE] => 1 [DELETE_RULE] => 1 [FK_NAME] => fk_game_athlete_code [PK_NAME] => pk_athlete_code ) [1] => Array ( [PKTABLE_NAME] => event [PKCOLUMN_NAME] => code [FKTABLE_NAME] => game [FKCOLUMN_NAME] => event_code [KEY_SEQ] => 1 [UPDATE_RULE] => 1 [DELETE_RULE] => 1 [FK_NAME] => fk_game_event_code [PK_NAME] => pk_event_code ) )
