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)); ?>
The above example will output:
array(3) { ["cherry"]=> array(1) { ["color"]=> string(3) "red" } ["strawberry"]=> array(1) { ["color"]=> string(3) "red" } ["lemon"]=> array(1) { ["color"]=> string(6) "yellow" } }
