Connecting to SQLite Database using Devart ODBC Driver in Python

When working with a SQLite database, you may need to execute SQL queries and retrieve data from your dataset. In this tutorial, we will explore how to connect to a SQLite database using the Devart ODBC Driver in Python.

To start, make sure you have the necessary modules installed on your machine. The first step is to import the pyodbc module, which is a Python extension for accessing ODBC databases. Next, create a connection to the database by specifying the driver name and other parameters such as the database path and username.

Once connected, you can execute SQL queries using the cursor.execute() function. For example, let's insert a new record into the EMP table using an INSERT statement:

```

cursor = cnxn.cursor()

cursor.execute('INSERT INTO EMP (EMPNO, ENAME, JOB, MGR) VALUES (535, 'Scott', 'Manager', 545)')

```

To test the connection to the database, you can add this code to a file with a `.py` extension and run it from the command prompt.

If you don't have Python installed on your machine, you can download it from the official website and follow the installation instructions. Additionally, you will need to install the pyodbc module using pip: `pip install pyodbc`.

After installing the necessary modules, you are ready to connect to your SQLite database using the Devart ODBC Driver. First, download the ODBC Driver for SQLite and follow the installation instructions to configure it as a translation layer between your application and the database.

Once installed, you can use the following code snippet to connect to your SQLite database:

```

import pyodbc

cnxn = pyodbc.connect('DRIVER=Devart ODBC Driver for SQLite;Direct=True;Database=mydatabase;String Types=Unicode')

cursor = cnxn.cursor()

cursor.execute('SELECT * FROM EMP')

for row in cursor.fetchall():

print(row)

```

In this example, we create a connection to the database using the `pyodbc.connect()` function and specify the driver name, database path, and other parameters. We then execute a SELECT query to retrieve all rows from the EMP table and print each row to the console.

By following these steps, you should be able to connect to your SQLite database using the Devart ODBC Driver in Python. This will allow you to execute SQL queries and retrieve data from your dataset, making it easier to work with your database in your Python application.
