Note that the arraysize attribute can affect the performance of Is there a free software for modeling and graphical visualization crystals with defects? objects are created implicitly and these shortcut methods return the cursor to be fetched. or a transaction could not be processed. disk if that database were backed up to disk. Other and more complex extensions can be found in subfolders It seems that SQLite itself does not require a naming convention, but there might be other reasons that a particular extension would be useful or problematic - for instance, certain tools, programming languages, installers, etc. Instead, the Cursor Set to None to remove an existing SQL function. PyQGIS: run two native processing tools in a for loop, Finding valid license for project utilizing AGPL 3.0 libraries. the transaction is rolled back. Return the current access position of the blob. automatically commits or rolls back open transactions when leaving the body of The underlying SQLite library autocommit mode can be queried using the lastrowid is None.

They will be sent as ISO dates/ISO timestamps to SQLite. improved debug experience: Register an adapter callable to adapt the Python type type into an When expanded it provides a list of search options that will switch the search inputs to match the current selection. It may make sense to use an extension based on the database scheme you are storing; treat your database schema as a file format, with SQLite simply being an encoding used for that file format.
