TABLE
TiDB 数据库中 TABLE 语句的使用概况。

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

语法图

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

示例

{{< copyable "sql" >}}

CREATE TABLE t1(id INT PRIMARY KEY);
Query OK, 0 rows affected (0.31 sec)

{{< copyable "sql" >}}

INSERT INTO t1 VALUES (1),(2),(3);
Query OK, 3 rows affected (0.06 sec)
Records: 3  Duplicates: 0  Warnings: 0

{{< copyable "sql" >}}

TABLE t1;
+----+
| id |
+----+
|  1 |
|  2 |
|  3 |
+----+
3 rows in set (0.01 sec)

{{< copyable "sql" >}}

TABLE t1 ORDER BY id DESC;
+----+
| id |
+----+
|  3 |
|  2 |
|  1 |
+----+
3 rows in set (0.01 sec)

{{< copyable "sql" >}}

TABLE t1 LIMIT 1;
+----+
| id |
+----+
|  1 |
+----+
1 row in set (0.01 sec)

MySQL 兼容性

TABLE 语句是从 MySQL 8.0.19 开始引入的。
