TABLE

当不需要聚合或复杂的过滤操作时，可以用 TABLE 语句代替 SELECT * FROM。

TableStmt ::=
    "TABLE" Table ( "ORDER BY" Column )? ( "LIMIT" NUM )?

CREATE TABLE t1(id INT PRIMARY KEY);

Query OK, 0 rows affected (0.31 sec)

INSERT INTO t1 VALUES (1),(2),(3);

Query OK, 3 rows affected (0.06 sec)
Records: 3  Duplicates: 0  Warnings: 0

TABLE t1;

+----+
| id |
+----+
|  1 |
|  2 |
|  3 |
+----+
3 rows in set (0.01 sec)

TABLE t1 ORDER BY id DESC;

+----+
| id |
+----+
|  3 |
|  2 |
|  1 |
+----+
3 rows in set (0.01 sec)

TABLE t1 LIMIT 1;

+----+
| id |

|  1 |

1 row in set (0.01 sec)

TABLE 语句是从 MySQL 8.0.19 开始引入的。
