Using Python to Operate ObjectivityDB

ObjectivityDB is a high-performance, object-oriented Database management system. In Python, the Pyodbc module can be used to operate ObjectivityDB database connections and perform data insertion, query, modification, and deletion operations. Firstly, before using pyodbc, it is necessary to install the pyodbc module. The installation command is as follows: pip install pyodbc After the installation is completed, you can use pyodbc to connect and operate the ObjectivityDB database. The following is a complete Python code example that demonstrates how to use Pyodbc to connect and operate ObjectivityDB databases: python import pyodbc #Connect to database conn = pyodbc.connect('DRIVER={Objectivity/DB ODBC Driver};SERVER=localhost;PORT=6677;UID=username;PWD=password') #Create Cursor cursor = conn.cursor() #Insert Data cursor.execute("INSERT INTO Employees (id, name, age) VALUES (?, ?, ?)", ('1', 'Alice', 25)) cursor.execute("INSERT INTO Employees (id, name, age) VALUES (?, ?, ?)", ('2', 'Bob', 30)) #Query data cursor.execute("SELECT * FROM Employees") rows = cursor.fetchall() for row in rows: print(row) #Modify data cursor.execute("UPDATE Employees SET age = ? WHERE name = ?", (35, 'Alice')) #Delete data cursor.execute("DELETE FROM Employees WHERE name = ?", ('Bob',)) #Commit transaction conn.commit() #Close cursors and connections cursor.close() conn.close() In the above code, first use Pyodbc's' connect 'function to establish a connection to the ObjectivityDB database. The connection string needs to specify information such as the database driver, server address, port number, username, and password. Then create a cursor using the 'cursor' method to execute SQL statements and obtain query results. Next, SQL statements such as Insert, SELECT, UPDATE, and DELETE can be executed using the 'execute' method. The 'fetchall' method can be used to obtain query results. After modifying and deleting data, the 'commit' method needs to be used to commit the transaction. Finally, remember to close the cursor and connection. It should be noted that the specific table names, field names, and SQL statements need to be modified according to the actual situation. Through the above code example, you should be able to use Python to connect and operate the ObjectivityDB database.
