PL/SQL provides the functionality of other procedural programming languages, such as decision making, iteration etc. A PL/SQL program unit is one of the following: PL/SQL anonymous block, procedure, function, package specification, package body, trigger, type specification, type body, library. Program units are the PL/SQL source code that is ...
In SQL, a window function or analytic function [1] is a function which uses values from one or multiple rows to return a value for each row. (This contrasts with an aggregate function, which returns a single value for multiple rows.) Window functions have an OVER clause; any function without an OVER clause is not a window function, but rather ...
To insert multiple rows in MS SQL you can use such a construction: INSERT INTO phone_book SELECT 'John Doe' , '555-1212' UNION ALL SELECT 'Peter Doe' , '555-2323' ; Note that this is not a valid SQL statement according to the SQL standard ( SQL:2003 ) due to the incomplete subselect clause.
PL/SQL Developer, an Integrated Development Environment for developing software in the Oracle database environment, [2] focuses on the development of PL/SQL stored-program units. Allround Automations, based in Enschede in the Netherlands , markets the software.
The design of PL/pgSQL aimed to allow PostgreSQL users to perform more complex operations and computations than SQL, while providing ease of use. The language is able to be defined as trusted by the server. [3] PL/pgSQL is one of the programming languages included in the standard PostgreSQL distribution, [4] the others being PL/Tcl, PL/Perl [5 ...
The SQL SELECT statement returns a result set of rows, from one or more tables. [1] [2] A SELECT statement retrieves zero or more rows from one or more database tables or database views. In most applications, SELECT is the most commonly used data manipulation language (DML) command.
Multiple sessions are automatically spread across all available CPUs by the operating system. Many types of queries can also be parallelized across multiple background worker processes, taking advantage of multiple CPUs or cores. [74] Client applications can use threads and create multiple database connections from each thread. [75]
PL/I (Programming Language One, pronounced / p iː ɛ l w ʌ n / and sometimes written PL/1) [1] is a procedural, imperative computer programming language initially developed by IBM. It is designed for scientific, engineering, business and system programming.
