“`python
import pymysql
Connection details
connection = pymysql.connect(
host=’your_host’,
user=’your_user’,
password=’your_password’,
database=’your_database’
)
try:
with connection.cursor() as cursor:
cursor.execute(“SELECT VERSION()”)
result = cursor.fetchone()
print(“Database Version: “, result)
finally:
connection.close()
“`
Replace 'your_host', 'your_user', 'your_password', and 'your_database' with your actual connection details.
Connecting to NoSQL Databases
Connecting to NoSQL databases is slightly different, but many are accessible via their APIs or SDKs.
Using a Database Client
For NoSQL databases like MongoDB, consider using MongoDB Compass:
- Download and Install Compass: This is the official GUI for MongoDB.
- Open Compass and Create a New Connection:
- Enter the connection string, which includes your username, password, and database host.
- Test and Connect: Compass will validate your connection string before connecting you.
Using a Programming Language
Similarly, you can connect to NoSQL databases programmatically. Below is an example with MongoDB using Python:
“`python
from pymongo import MongoClient
Connection details
client = MongoClient(‘your_connection_string’)
Accessing the database
db = client[‘your_database’]
collection = db[‘your_collection’]
Sample query
for document in collection.find():
print(document)
“`
Replace 'your_connection_string', 'your_database', and 'your_collection' as necessary.
Best Practices for Connecting to Cloud Databases
While connecting to a cloud database can be straightforward, following best practices ensures security and reliability.
1. Use Environment Variables for Credentials
Avoid hardcoding sensitive information like database credentials in your code. Instead, use environment variables to store your connection details securely.
