Query to count the number of tables I have in MySQL

mysql

I am growing the number of tables I have and I am sometimes curious just to do a quick command line query to count the number of tables in my database. Is that possible? If so, what is the query?

Solution 1:

SELECT COUNT(*) FROM information_schema.tables WHERE table_schema = 'dbName';

Source

This is mine:

USE databasename; 
SHOW TABLES; 
SELECT FOUND_ROWS();

Solution 2:

In case you would like a count all the databases plus a summary, please try this:

SELECT IFNULL(table_schema,'Total') "Database",TableCount 
FROM (SELECT COUNT(1) TableCount,table_schema 
      FROM information_schema.tables 
      WHERE table_schema NOT IN ('information_schema','mysql') 
      GROUP BY table_schema WITH ROLLUP) A;

Here is a sample run:

mysql> SELECT IFNULL(table_schema,'Total') "Database",TableCount
    -> FROM (SELECT COUNT(1) TableCount,table_schema
    ->       FROM information_schema.tables
    ->       WHERE table_schema NOT IN ('information_schema','mysql')
    ->       GROUP BY table_schema WITH ROLLUP) A;
+--------------------+------------+
| Database           | TableCount |
+--------------------+------------+
| performance_schema |         17 |
| Total              |         17 |
+--------------------+------------+
2 rows in set (0.29 sec)

Give it a Try !!!

Solution 3:

SELECT COUNT(*) FROM information_schema.tables WHERE table_schema = 'dbo' and TABLE_TYPE='BASE TABLE'

Solution 4:

This will give you names and table count of all the databases in you mysql

SELECT TABLE_SCHEMA,COUNT(*) FROM information_schema.tables group by TABLE_SCHEMA;

Solution 5:

To count number of tables just do this:

USE your_db_name;    -- set database
SHOW TABLES;         -- tables lists
SELECT FOUND_ROWS(); -- number of tables

Sometimes easy things will do the work.
