Using Python to Operate Microsoft Access

To operate a Microsoft Access database using Python, you can use the pyodbc library. Pyodbc is a library that follows the Python DB API 2.0 specification and is used to connect and operate various databases, including Microsoft Access. Firstly, it is necessary to ensure that the pyodbc library has been installed. You can use the following command to install pyodbc: pip install pyodbc Next, we will explain step by step how to connect and operate Microsoft Access databases. 1. Connect to the database python import pyodbc #Connect to database conn = pyodbc.connect('DRIVER={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=path/to/your/database.accdb;') #Create a cursor object cursor = conn.cursor() In the above code, you need to replace 'path/to/your/database. accdb' with the actual database file path. 2. Insert Data python #Insert a piece of data cursor.execute("INSERT INTO table_name (column1, column2) VALUES (?, ?)", ('value1', 'value2')) #Commit transaction conn.commit() In the above code, "tablename" is the table name to insert data into, "column1" and "column2" are the field names to insert data into, and "value1" and "value2" are the actual values to insert. 3. Query data python #Query data cursor.execute('SELECT * FROM table_name') #Obtain query results rows = cursor.fetchall() #Print query results for row in rows: print(row) In the above code, "tablename" is the name of the table to be queried, and "cursor. fetchall()" is used to obtain all query results, which can be processed line by line in a loop. 4. Modify data python #Modify data cursor.execute('UPDATE table_name SET column1 = ? WHERE id = ?', ('new_value', 1)) #Commit transaction conn.commit() In the above code, "tablename" is the table name to modify the data, "column1" is the field name to modify, "new_value" is the new value to modify, and "id" is the condition used to locate the data to be modified. 5. Delete data python #Delete data cursor.execute('DELETE FROM table_name WHERE id = ?', (1,)) #Commit transaction conn.commit() In the above code, "tablename" is the table name where the data is to be deleted, and "id" is the condition used to locate the data to be deleted. After completing the database operation, remember to close the connection: python #Close cursors and connections cursor.close() conn.close() The above are the basic steps and sample code for using Python to operate a Microsoft Access database. According to actual needs, more methods provided by Pyodbc can be called to complete more complex database operations.
