If cursor not updating rollback is required

It is self-contained, serverless, zero-configuration and transactional.It is very fast and lightweight, and the entire database is stored in a single disk file.It is used in a lot of applications as internal data storage.The Python Standard Library includes a module called "sqlite3" intended for working with this database.Sharing in the above context means that two threads may use a resource without wrapping it using a mutex semaphore to implement resource locking.Note that you cannot always make external resources thread safe by managing access using a mutex: the resource may rely on global variables or other external sources that are beyond your control.

Never insert a COMMIT WORK between the first and last table update inside a program or transaction, if the entries are logically related.SQL Return Codes are used on a day-to-day basis for the diagnosis of programming failures as a result of SQL calls by DB2 computer programs.An important feature of DB2 programs is the error processing.The previous version 1.0 version is still available as reference, in PEP 248.Package writers are encouraged to use this version of the specification as basis for new interfaces.
