How to Show All Tables in MySQL using Python?

Last Updated : 29 Sep, 2021

A connector is employed when we have to use mysql with other programming languages. The work of mysql-connector is to provide access to MySQL Driver to the required language. Thus, it generates a connection between the programming language and the MySQL Server.

In order to make python interact with the MySQL database, we use Python-MySQL-Connector. Here we will try implementing SQL queries which will show the names of all the tables present in the database or server.

Syntax:

To show the name of tables present inside a database:

SHOW Tables;

To show the name of tables present inside a server:

SELECT table_name

FROM information_schema.tables;

Database in use:

Schema of the database used

The following programs implement the same.

Example 1: Display table names present inside a database:

Python3

import mysql.connector
 
mydb = mysql.connector.connect(
    host="localhost",
    user="root",
    password="",
    database="gfg"
)
 
mycursor = mydb.cursor()
 
mycursor.execute("Show tables;")
 
myresult = mycursor.fetchall()
 
for x in myresult:
    print(x)

Output:

Table names in gfg database

Example 2: Display table names present inside a server:

Python3

import mysql.connector
 
mydb = mysql.connector.connect(
  host="localhost",
  user="root",
  password="",
)
 
mycursor = mydb.cursor()
 
mycursor.execute("SELECT table_name FROM information_schema.tables;")
 
myresult = mycursor.fetchall()
 
for x in myresult:
  print(x)

Output:

Table names in server
