cubrid_get — Get a column using OID
Beschreibung
The cubrid_get() function is used to get the attribute
of the instance of the given oid. You can get
single attribute by using string data type for the
attr argument, or many attributes by using array
data type for the attr argument.
Parameter-Liste
-
conn_identifier -
Connection identifier.
-
oid -
OID of the instance that you want to read.
-
attr -
Name of the attribute that you want to read.
Rückgabewerte
Content of the requested attribute, when process is successful; When
attr is set with string data type, the result is
returned as a string; when attr is set with array
data type (0-based numerical array), then the result is returned in
associative array. When attr is omitted, then all
attributes are received in array form.
false when process is unsuccessful or result is NULL (If error occurs to
distinguish empty string from NULL, then it prints the warning message.
You can check the error by using cubrid_error_code())

Beispiel #1 cubrid_get() example
<?php
$conn = cubrid_connect("localhost", 33000, "demodb");
@cubrid_execute($conn, "DROP TABLE foo");
cubrid_execute($conn, "CREATE TABLE foo(a int AUTO_INCREMENT, b set(int), c list(int), d char(10))");
cubrid_execute($conn, "INSERT INTO foo(a, b, c, d) VALUES(1, {1,2,3}, {11,22,33,333}, 'a')");
cubrid_execute($conn, "INSERT INTO foo(a, b, c, d) VALUES(2, {4,5,7}, {44,55,66,666}, 'b')");
$req = cubrid_execute($conn, "SELECT * FROM foo", CUBRID_INCLUDE_OID);
cubrid_move_cursor($req, 1, CUBRID_CURSOR_FIRST);
$oid = cubrid_current_oid($req);
$attr = cubrid_get($conn, $oid, "b");
var_dump($attr);
$attr = cubrid_get($conn, $oid);
var_dump($attr);
cubrid_close_request($req);
cubrid_disconnect($conn);
