Example #1 TokyoTyrantQuery::metaSearch() example

<?php/* Connect to a table database */$tt = new TokyoTyrantTable("localhost", 1979);/* Add test data */$tt->put('cherry',     array('color' => 'red'));$tt->put('strawberry', array('color' => 'red'));$tt->put('apple',      array('color' => 'green'));$tt->put('lemon',      array('color' => 'yellow'));/* First query */$query = $tt->getQuery();$query->addCond('color', TokyoTyrant::RDBQC_STREQ, 'red')->setOrder('color', TokyoTyrant::RDBQO_STRASC);/* Second query */$query1 = $tt->getQuery();$query1->addCond('color', TokyoTyrant::RDBQC_STREQ, 'yellow');/* Get union between the queries */var_dump($query->metaSearch(array($query1), TokyoTyrant::RDBMS_UNION));?>

以上例程会输出：

array(3) {
  ["cherry"]=>
  array(1) {
    ["color"]=>
    string(3) "red"
  }
  ["strawberry"]=>
  array(1) {
    ["color"]=>
    string(3) "red"
  }
  ["lemon"]=>
  array(1) {
    ["color"]=>
    string(6) "yellow"
  }
}
