The main "gadfly" module attempts to faithfully adhere to Greg Stein's Python Database API, ... Multiple statements may be executed in one cursor.execute(S) by ...
In computer science, a database cursor is a mechanism that enables traversal over the records in a database. Cursors facilitate processing in conjunction with the traversal, such as retrieval, addition and removal of database records. The database cursor characteristic of traversal makes cursors akin to the programming language concept of iterator.
Major DBMSs, including SQLite, [5] MySQL, [6] Oracle, [7] IBM Db2, [8] Microsoft SQL Server [9] and PostgreSQL [10] support prepared statements. Prepared statements are normally executed through a non-SQL binary protocol for efficiency and protection from SQL injection, but with some DBMSs such as MySQL prepared statements are also available using a SQL syntax for debugging purposes.
Storm is a Python programming library for object-relational mapping between one or more SQL databases and Python objects. It allows Python developers to formulate complex queries spanning multiple database tables to support dynamic storage and retrieval of object information.
The receiver object owns the method that is called by the command's execute method. The receiver is typically also the target object. For example, if the receiver object is a cursor and the method is called moveUp, then one would expect that the cursor is the target of the moveUp action. On the other hand, if the code is defined by the command ...
In computer programming, create, read, update, and delete (CRUD) are the four basic operations (actions) of persistent storage. [1] CRUD is also sometimes used to describe user interface conventions that facilitate viewing, searching, and changing information using computer-based forms and reports.
An example of a Python generator returning an iterator for the Fibonacci numbers using Python's yield statement follows: def fibonacci ( limit ): a , b = 0 , 1 for _ in range ( limit ): yield a a , b = b , a + b for number in fibonacci ( 100 ): # The generator constructs an iterator print ( number )
RethinkDB was founded in 2009, and open-sourced at version 1.2 in 2012. [5] In 2015, RethinkDB released version 2.0, announcing that it was production-ready. [6] On October 5, 2016, the company announced it was shutting down, transitioning members of its engineering team to Stripe, and would no longer offer production support.
