查询数据库中的表名

查询编程客栈一个数据库中含有某关键词的表名

搜索一个数据库中包含一些关键字，词的表。

SELECT
  TABLE_NAME
FROM
  information_schema. TABLES
WHERE
  table_schema = '数据库名'
  AND TABLE_NAME LIKE '%name%';

例：

mysql> select table_name from information_schema.tables
  -> where table_schema = 'sakila'
  -> and table_name like "%film%";
+----------------------------+
| TABLE_NAME         |
+----------------------------+
| film            |
| film_actor         |
| film_category       |
| film_list         |
| film_text       编程客栈  |
| nicer_but_slower_film_list |
| sales_by_film_category   |
+----------------------------+
7 rows in set (0.00 sec)

  

查询数据库中所有的表

show tables；
-- use 数据库名
USE sakila;
SHOW TABLES;

同上面，where条件只查数据库名。还可以同时搜索多个数据库中的表。

SELECT
  TABLE_NAME
FROM
  information_schema. TABLES
WHERE
  table_schema = '数据库名';

例：

mysql&gjavascriptt; select table_name from information_schema.tables where table_schema = 'sakila';
+----------------------------+
| TABLE_NAME         |
+----------------------------+
| actor           |
| actor_info         |
| address          |
| category          |
| city            |
| country          |
| customer          |
| customer_list       |
| film            |
| film_actor         |
| film_category       |
| film_list         |
| film_text         |
| inventory         |

| store           |
+----------------------------+
