You can pass \":memory:\" to create an SQLite database existing only in memory < and open a connection to it. :type database: path-like object\n\nparam float timeout: How many seconds the connection should wait before raising an OperationalError when a table is locked. If another connection opens a transaction to modify a table, that table will be locked until the transaction is committed. Default five seconds.\n\nparam int detect_types: Control whether and how data types not natively supported by SQLite are looked up to be converted to Python types, using the converters registered with register_converter. Set it to any combination (using |, bitwise or) of PARSE_DECLTYPES and PARSE_COLNAMES to enable this. Column names take precedence over declared types if both flags are set. By default (0), type detection is disabled.\n\nparam isolation_level: Control legacy transaction handling behaviour. See Connection.isolation_level and sqlite3-transaction-control-isolation-level for more information. Can be \"DEFERRED\" (default), \"EXCLUSIVE\" or \"IMMEDIATE\"; or None to disable opening transactions implicitly. Has no effect unless Connection.autocommit is set to ~sqlite3.LEGACY_TRANSACTION_CONTROL (the default). :type isolation_level: str | None\n\nparam bool check_same_thread: If True (default), ProgrammingError will be raised if the database connection is used by a thread other than the one that created it. If False, the connection may be accessed in multiple threads; write operations may need to be serialized by the user to avoid data corruption. See threadsafety for more information.\n\nparam ~sqlite3.Connection factory: A custom subclass of Connection to create the connection with, if not the default Connection class.\n\nparam int cached_statements: The number of statements that !sqlite3 should internally cache for this connection, to avoid parsing overhead. By default, 128 statements.\n\nparam bool uri: If set to True, database is interpreted as a URI (Uniform Resource Identifier) with a file path and an optional query string. The scheme part must be \"file:\", and the path can be relative or absolute. The query string allows passing parameters to SQLite, enabling various sqlite3-uri-tricks. …\n\nAttribution: Adapted from Python Documentation under PSF-2.0.
