Example #1 mysql_xdevapi\Table::existsInDatabase() example
<?php
$session = mysql_xdevapi\getSession("mysqlx://user:password@localhost");
$session->sql("DROP DATABASE IF EXISTS addressbook")->execute();
$session->sql("CREATE DATABASE addressbook")->execute();
$session->sql("CREATE TABLE addressbook.names(name text, age int)")->execute();
$session->sql("INSERT INTO addressbook.names values ('John', 42), ('Sam', 33)")->execute();
$schema = $session->getSchema("addressbook");
$table = $schema->getTable("names");
if ($table->existsInDatabase()) {
echo "Yes, this table still exists in the session's schema.";
}
?>Il precedente esempio visualizzerà qualcosa simile a:
Yes, this table still exists in the session's schema.
