See sqlite3-transaction-control-isolation-level for more information.\n\nPass this flag value to the detect_types parameter of connect to look up a converter function using the declared types for each column. The types are declared when the database table is created. !sqlite3 will look up a converter function using the first word of the declared type as the converter dictionary key. For example\n\nBounded code example (external data; do not execute automatically):\n```sql\nCREATE TABLE test(\ni integer primary key,  ! will look up a converter named \"integer\"\np point,                ! will look up a converter named \"point\"\nn number(10)            ! will look up a converter named \"number\"\n)\n\nThis flag may be combined with :const:`PARSE_COLNAMES` using the ``|``\n(bitwise or) operator.\n\n.. note::\n\nGenerated fields (for example ``MAX(p)``) are returned as :class:`str`.\nUse :const:`!PARSE_COLNAMES` to enforce types for such queries.\n```\n\nPass this flag value to the detect_types parameter of connect to look up a converter function by using the type name, parsed from the query column name, as the converter dictionary key. The query column name must be wrapped in double quotes (\") and the type name must be wrapped in square brackets ([]).\n\nBounded code example (external data; do not execute automatically):\n```sql\nSELECT MAX(p) as \"p [point]\" FROM test;  ! will look up converter \"point\"\n\nThis flag may be combined with :const:`PARSE_DECLTYPES` using the ``|``\n(bitwise or) operator.\n```\n\nFlags that should be returned by the authorizer_callback callable passed to Connection.set_authorizer, to indicate whether\n\nAccess is allowed (!SQLITE_OK), The SQL statement should be aborted with an error (!SQLITE_DENY) The column should be treated as a NULL value (!SQLITE_IGNORE)\n\nString constant stating the supported DB-API level. Required by the DB-API. Hard-coded to \"2.0\".\n\nString constant stating the type of parameter marker formatting expected by the !sqlite3 module. Required by the DB-API. Hard-coded to \"qmark\".\n\nVersion number of the runtime SQLite library as a string .\n\nVersion number of the runtime SQLite library as a tuple of integers .\n\nA tuple containing all SQLite keywords.\n\nThis constant is only available if Python was compiled with SQLite 3.24.0 or greater. …\n\nAttribution: Adapted from Python Documentation under PSF-2.0.
