Example #1 TokyoTyrantQuery::addCond() example

<?php
/* Connect to a table database */
$tt = new TokyoTyrantTable("localhost"1979);

/* Add rows */
$tt->put(null, array("column1" => "some data""column2" => "something here"));
$tt->put(null, array("column1" => "more data""column2" => "best data this far"));
$tt->put(null, array("column1" => "again data""column3" => "not here"));
$tt->put(null, array("column45" => "random data""column2" => "something along the lines"));
$tt->put(null, array("column21" => "test data""column2" => "generating.."));
$tt->put(null, array("column1" => "foobar data""column2" => "value here"));

/* Get a new query object */
$query $tt->getQuery();

/* Add a search condition */
$query->addCond("column2"TokyoTyrant::RDBQC_STROR"something");

/* Dump the search results */
var_dump($query->search());
?>

以上例程会输出:

array(2) {
  [1]=>
  array(2) {
    ["column1"]=>
    string(9) "some data"
    ["column2"]=>
    string(14) "something here"
  }
  [4]=>
  array(2) {
    ["column45"]=>
    string(11) "random data"
    ["column2"]=>
    string(25) "something along the lines"
  }
}
