查询数据库中的表名

查询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                  |
| 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> select table_name from information_schema.tables where table_schema = 'sakila';
+----------------------------+
| TABLE_NAME                 |
+----------------------------+
