This routine creates a cursor which will be used throughout of your database programming with Python. You can specify filename with the required path as well if you want to create a database anywhere else except in the current directory. If the given database name does not exist then this call will create the database.
The default for the timeout parameter is 5.0 (five seconds). The timeout parameter specifies how long the connection should wait for the lock to go away until raising an exception. When a database is accessed by multiple connections, and one of the processes modifies the database, the SQLite database is locked until that transaction is committed. If database is opened successfully, it returns a connection object. You can use ":memory:" to open a database connection to a database that resides in RAM instead of on disk. This API opens a connection to the SQLite database file. If you are looking for a more sophisticated application, then you can look into Python sqlite3 module's official documentation. Python sqlite3 module APIsįollowing are important sqlite3 module routines, which can suffice your requirement to work with SQLite database from your Python program.
To use sqlite3 module, you must first create a connection object that represents the database and then optionally you can create a cursor object, which will help you in executing all the SQL statements. You do not need to install this module separately because it is shipped by default along with Python version 2.5.x onwards. It provides an SQL interface compliant with the DB-API 2.0 specification described by PEP 249. SQLite3 can be integrated with Python using sqlite3 module, which was written by Gerhard Haring.
