General info

In this project, we will examine how to connect a database with Python code in windows and macOS operating systems

Technologies

Project is created with:

• Python version: 3.10.0
• pip version: 21.3.1
• Mysql Connector python Version for win64: > https://bit.ly/3HJg57l

Setup

• To run this project,You must first Step install the Python connector and the mysql database on the system: in Cmd(Windows Command Line)(os = windows) or Terminal(os= MacOs)
• In the second Step, we write a series of Python code related to the database connection in the IDE

in Windows Command Line(CMD):

@@ pip install mysql-connector-python @@

Important note:

Note that if you do not write the word 'Python' at the end of the command, you will encounter this error:

• mysql.connector.errors.NotSupportedError: Authentication plugin 'caching_sha2_password' is not supported

in Terminal MacOs:

@@ sudo apt-get install mysql-connector-python @@

After:

@@ pip install mysql-connector-python @@

Now we go to the Python code section in the corresponding IDE( Like vscode:)))) ):

+ #import my SQL/Python Connector on CodeSpace
import mysql.connector
+ #Send and Pour Information Database With one variable
mydb = mysql.connector.connect(host="your host name",user="your user name",password="your pass",database='your database name')

+ #Create Cursor on Cmd Structure
cursor = mydb.cursor()
+ #Execute MySQL Code On CMD space
cursor.execute(cursor.execute('INSERT INTO people VALUES ("YOUR VALUEWS)')
+ #do 
mydb.commit()
cursor.close()
mydb.close() 
print(mydb)

Important note:

Note that Python must be installed on your system + Python pip must also + python and SQL connector Be installed

A series of MYSQL code commands:

SELECT - extracts data from a database

UPDATE - updates data in a database

DELETE - deletes data from a database

INSERT INTO - inserts new data into a database

CREATE DATABASE - creates a new database

ALTER DATABASE - modifies a database

CREATE TABLE - creates a new table

ALTER TABLE - modifies a table

DROP TABLE - deletes a table

CREATE INDEX - creates an index (search key)

DROP INDEX - deletes an index
