范例

Example #1 cubrid_lock_write() example

  <?php
$conn  =  cubrid_connect ( "localhost" ,  33000 ,  "demodb" ,  "dba" );

@ 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 );

 cubrid_lock_write ( $conn ,  $oid );

 $attr  =  cubrid_col_get ( $conn ,  $oid ,  "b" );
 var_dump ( $attr );

 cubrid_put ( $conn ,  $oid ,  "b" , array( 2 ,  4 ,  8 ));

 $attr  =  cubrid_col_get ( $conn ,  $oid ,  "b" );
 var_dump ( $attr );

 cubrid_close_request ( $req );
 cubrid_disconnect ( $conn );
 ?>

以上例程会输出：

array(3) {
  [0]=>
  string(1) "1"
  [1]=>
  string(1) "2"
  [2]=>
  string(1) "3"
}
array(3) {
  [0]=>
  string(1) "2"
  [1]=>
  string(1) "4"
  [2]=>
  string(1) "8"
}
