Oracle updating cursor
SQLite is a C library that provides a lightweight disk-based database that doesn’t require a separate server process and allows accessing the database using a nonstandard variant of the SQL query language.Some applications can use SQLite for internal data storage.It’s also possible to prototype an application using SQLite and then port the code to a larger database such as Postgre SQL or Oracle. It provides a SQL interface compliant with the DB-API 2.0 specification described by Usually your SQL operations will need to use values from Python variables.
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.The contains one or more complete SQL statements terminated by semicolons.It does not verify that the SQL is syntactically correct, only that there are no unclosed string literals and the statement is terminated by a semicolon.This can be used to build a shell for SQLite, as in the following example: . It should return -1 if the first is ordered lower than the second, 0 if they are ordered equal and 1 if the first is ordered higher than the second.Note that this controls sorting (ORDER BY in SQL) so your comparisons don’t affect other SQL operations.
