PYTHON MYSQL CONNECTOR CODE

We need to import this mysqlclient in our code to import the MySQLdb library, as shown in our coding example below. The only difference from the previous methods is that the library’s name imported isn’t the same as the name used during installation.

PYTHON MYSQL CONNECTOR INSTALL

!pip install mysqlclientĪfter installation, we need to apply the same steps mentioned in the first section. To install this library, we need to execute the following command. Connect to a MySQL Database With the mysqlclient Library in PythonĪnother great way of connecting to a MySQL database in Python is the mysqlclient library. The only noticeable difference here is in the name of the imported library. The output is the same as the previous section because we connected to the same database and executed the same query. import pymysqlĬonnection = nnect(host='localhost', The code example below shows us how we can connect to a MySQL database and execute a query with the pymysql library in Python. Even the names of the methods in the pymysql library are the same as in the default Python connector. !pip install pymysqlĪfter installing, we need to follow the same steps described in the previous section. The command to install the pymysql library is given below. There are also no compatibility or interoperability issues in the pymysql library because it is written in pure Python. Instead of going the easy way and using Oracle’s default python MySQL connector, we can also use the pymysql library to connect to a MySQL database. Connect to a MySQL Database With the pymysql Library in Python There are subtle bugs that come with the standard MySQL connector provided by Oracle, and hence this approach is not encouraged. cursor.close()Īlthough it is the easiest method to get a MySQL database connected with Python, it has flaws. for i in cursor:Īfter executing our queries, we need to close our cursor and connect with the following code. The code snippet below shows us how we can do that. We have to loop over the cursor and display each value separately to display the results. This doesn’t show any output because the query’s result is stored inside the cursor. The method to execute queries with the cursor is shown in the following code snippet. We must use the execute() function inside the cursor object to perform a particular query. Once the cursor is created, we can execute our queries. This is shown in the following code snippet. We need to execute the cursor() inside our connection object to create a cursor. This is done by something called a cursor.Ī cursor acts as a pointer used to perform operations on the database and its tables. We need a way to perform CRUD (Create, Read, Update, Delete) operations on the database. We used connector.Error to report any errors on the runtime while connecting to the database. Print("Error: Could not make connection to the MySQL database") The code snippet below shows us how we can create a connection with exception handling in Python. Exception handling is a crucial part of database programming in any programming language. We need to wrap this line of code inside a try/except block for exception handling.

PYTHON MYSQL CONNECTOR PASSWORD

the password parameter specifies the password of that specific user,.The user parameter specifies the name of the user currently logged in,.This method takes the user, password, host, and the database as input parameters. We can now refer to this library using the connector alias.Īfter importing the library, we need to create a connection with the connect() method. We’ve imported the nnector library and given it the alias connector. The procedure is shown in the following line. !pip install mysql-connector-pythonĪfter the installation, we need to import this library into our code file. The command to install the MySQL connector for Python is given below.

PYTHON MYSQL CONNECTOR DOWNLOAD

We can either manually download and install the connector from the official webpage or install it through the command prompt. It is the easiest way to connect to a MySQL database in Python. Oracle has provided a connector for Python to connect to its MySQL databases. Connect to a MySQL Database With the Default MySQL Connector for Python
