In my next article, I will share details on how to execute "Stored Procedures" and more python with MySQL examples. # using while loop to reterive the records # del_sql = "DELETE FROM CUST.CUSTOMER WHERE CUST_ID = 102" # upd_sql = "UPDATE CUST.CUSTOMER SET CITY = 'BRONX' WHERE CITY = 'JERSEY'"
# my_cursor.executemany(insert_sql,data1)
# insert_sql= "INSERT INTO CUST.CUSTOMER(cust_id,nme,city) VALUES(%s,%s,%s)"
# create_tbl = "CREATE TABLE CUST.CUSTOMER ( CUST_ID INT, NME VARCHAR(50),CITY VARCHAR(10))"

Ĭreate Table: #Create new table customers in CUST databaseĬreate_tbl = "CREATE TABLE CUST.CUSTOMER ( CUST_ID INT, NME VARCHAR(50),CITY VARCHAR(10))"Ĭomplete Code Snippet import nnector My preference is to use variables to have the code clean. In other way the sql statement can be directly written in the execute method. I have assigned the statement to a variable named create_db d passing that variable to execute method. Second Step to import the library: Open your python file and write the following code: import nnector. After the installation go the second step.
#PYTHON MYSQL CONNECTOR INSTALL#
In order to execute the database commands, let's create instance to the mydb object and pass the SQL Statements. First step to get The Library: Open terminal and execute pip install mysql-python-connector. To start with ,let's create a new database from python code. is_connected() method will help us to validate whether our connection is successful or not. Next step is to validate whether our connection is successful or not. As mentioned above ,I have created a new user named "dev" and password. In this example, I am connecting to my local instance of MySQL. Invoke the connect method by passing the server credentials that we need to connect. In order to connect to Mysql, we need to import the Mysql connector library. I will use the visual studio IDE that was installed as part of Python installation import nnector Let's move on to write python code to connect to the MySQL database. The pip install command always looks for the latest version of the package and installs it. pip command looks for the package in PyPI, resolves its dependencies, and installs everything in your current Python environment to ensure that requests will work. Open a command prompt window and type "pip install mysql-connector-python". It is recommended to create new connection to avoid using "root" user You can also establish connection to MySQL by passing credentials (user name, password, hostname, and database name) to connection.MySQLConnection() as shown below −Ĭonn = connection.MySQLConnection(user='root', password='password', host='127.0.0.In the above screenshot, I have setup a new connection named "dev". On executing, this script produces the following output − Print("Connection established to: ",data) # Fetch a single row using fetchone() method. #Executing an MYSQL function using the execute() method > import nnector > (host 'localhost' ,database 'mysql' ,user 'root' ,password 'your pass') Code language: Python (python) If you see the following output, it means that you have been successfully. #Creating a cursor object using the cursor() method To verify the installation, you use the following steps: Open Python command line. Exampleįollowing is the example of connecting with MySQL database "mydb".Ĭonn = (user='root', password='password', host='127.0.0.1', database='mydb') This accepts username, password, host and, name of the database you need to connect with (optional) and, returns an object of the MySQLConnection class. You can establish a connection using the connect() constructor. The credentials we are using to connect with MySQL are username: root, password: password. We have created a table EMPLOYEE with columns FIRST_NAME, LAST_NAME, AGE, SEX and INCOME. That we have created a database with name mydb. You can disconnect from the MySQL database any time using the exit command at mysql> prompt.Įstablishing connection with MySQL using pythonīefore establishing connection to MySQL database using python, assume − Type '\c' to clear the current input statement.

#PYTHON MYSQL CONNECTOR PASSWORD#
It asks for password here you need to type the password you have set to the default user (root) at the time of installation. To connect with MySQL, (one way is to) open the MySQL command prompt in your system as shown below − This is a repository for reference of MySQL Connector lesson in 2021 Mini Workshop Series: Into Coding: Introduction to Python Libraries.
