返回最后一条执行的 SQL 语句.

last_query()Return: [string]和 log() 很相似，但只返回最后一次执行的 SQL 语句

$database->select("account", [
    "user_name",
    "email"], [
    "user_id[ 20]
);
$database->insert("account", [
    "user_name" => "foo",
    "email" => "foo@bar.com"]
);
echo $database->last_query();
// INSERT INTO "account" ("user_name", "email") VALUES ('foo', 'foo@bar.com')
