データベースから10個のランダムなデータを取得する4つの方法

SELECT TOP 10 * FROM T_USER ORDER BY NEWID()

SELECT * FROM (SELECT * FROM T_USER ORDER BY DBMS_RANDOM.RANDOM()) WHERE RONUM <= 10

SELECT * FROM T_USER ORDER BY RAND() LIMIT 10

SELECT TOP 10 * FROM T_USER ORDER BY rnd([an autonumber field])

Random random = new Random(System.Guid.NewGuid().GetHashCode());
int r = random.Next();
string sql = "SELECT TOP 10 * FROM T_USER ORDER BY RND(" + (-r) + "* autonumber field)"
