We can create as many cursors as we want from a single connection object.Using a connection object, we can create a cursor object which allows us to execute SQLite command/queries through Python.In our example, we passed the database name argument to connect. The connect() method accepts various arguments.If you still try to do so, you will get an exception at runtime. The sqlite3 module doesn’t allow sharing connections between threads. The connection object is not thread-safe.SQLite_Python_db Important points while connecting to SQLite Catch database exception if any that may occur during this connection process.Use cursor.clsoe() and connection.clsoe() method to close the cursor and SQLite connections after your work completes
Use cursor.fetchall() or fetchone() or fetchmany() to read query result. The execute() methods run the SQL query and return the result.
Use the cursor() method of a connection class to create a cursor object to execute SQLite command/queries from Python. This method returns the SQLite Connection Object if the connection is successful. But if your specified SQLite database file doesn’t exist, SQLite creates a new database for you. If you specify the database file name that already presents on the disk, it will connect to it. To establish a connection to SQLite, you need to pass the database name you want to connect. Use the connect() method of the connector class with the database name. Using the classes and methods defined in the sqlite3 module we can communicate with the SQLite database. Import sqlite3 statement imports the sqlite3 module in the program.
