SQL CLR or SQLCLR SQL Common Language Runtime is technology for hosting of the Microsoft .NET common language runtime engine within SQL Server. The SQLCLR allows managed code to be hosted by, and run in, the Microsoft SQL Server environment. This technology, introduced in Microsoft SQL Server 2005, allow users for example to create the following types of managed code objects in SQL Server in .NET languages such as C Sharp programming language C or VB.NET . Stored procedure s SPs which are analogous to procedures or void functions in procedural languages like VB or C, Database trigger triggers which are stored procedures that fire in response to Data Manipulation Language DML or Data Definition Language DDL events, User defined function s UDFs which are analogous to functions in procedural languages, User defined aggregate s UDAs which allow developers to create custom aggregates that act on sets of data instead of one row at a time, User defined type s UDTs that allow users to create simple or complex data types which can be serialized and deserialized within the database. The SQL CLR relies on the creation, deployment, and registration of .NET assemblies , which are physically stored in managed code dynamic load libraries DLLs . These assemblies may contain .NET namespaces, classes, functions and properties.

PRTV Peterlee Relational Test Vehicle was the world s first relational database management system that could handle significant data volumes. It was a relational query system with powerful query facilities, but very limited update facility and no simultaneous multiuser facility.

multiple issues notability September 2011 unreferenced September 2011 MaxScript command processor is an interpreter that implements a subset of the Xbase xBase programming language especially conceived to be used inside web pages to provide server side scripting capabilities. MaxScript is not to be confused with MAXScript, the scripting language of the 3D animation package 3ds Max . As a command processor, MaxScript needs a web server to work with whenever the web server receives a request for a MaxScript page it must pass it to the interpreter, that parses all the lines, top to bottom, in search of xBase cod to be executed. Then the page is passed back to web server that deliveries it to web browser. MaxScript pages use the file extension .MSP. MSP pages are standard HTML pages they can contain XHTML and Javascript code, as well as xBase code. xBase statements can consist on hundreds of lines or single function calls, always included into HTML server side tags. Tags for maxScript are similar to those used for PHP and other server side scripting languages to start xBase code into a web page the tag must be used. The tag marks the end of code. MaxScript is used as the core of freeware products like dbfree and in its commercial counterpart http www.dbmax.it DBMax The latest version 2.21 is dated 2008 and implements a large subset of xBase commands and functions, and the capability of writing UDFs User Defined Function to be integrated in the language. MaxScript was expressly designed to dynamically present live data on the internet and acts as a web server extension to process xBase Clipper code from inside an HTML page. As such the interpreter needs a web server to work with, and all the pages to be processed must reside on a web site accessible to it. The MaxScript Engine comes in form of a win32 executable and implements an xBase, Clipper like, programming language reach of features, commands and functions for any and all web application purposes, and uses built in ... more details

A stored procedure is a subroutine available to applications that access a relational database relational database management system database system . A stored procedure sometimes called a proc , sproc , StoPro , StoredProc , or SP is actually stored in the database data dictionary . Typical uses for stored procedures include data validation integrated into the database or access control mechanisms. Furthermore, stored procedures can consolidate and centralize logic that was originally implemented in applications. Extensive or complex processing that requires execution of several SQL statements is moved into stored procedures, and all applications call the procedures. One can use nested stored procedures, by executing one stored procedure from within another. Stored procedures are similar to user defined function user defined functions UDFs . The major difference is that UDFs can be used like any other expression within SQL statements, whereas stored procedures must be invoked using the code CALL code statement. ref http publib.boulder.ibm.com infocenter iseries v5r3 index.jsp?topic db2 rbafzmstcallstmt.htm Call Procedure ref CALL procedure ... or EXECUTE procedure ... Stored procedures may return result set s, i.e. the results of a code SELECT code statement. Such result sets can be processed using cursor databases cursor s, by other stored procedures, by associating a result set locator, or by applications. Stored procedures may also contain declared variables for processing data and cursors that allow it to loop through multiple rows in a table. Stored procedure languages typically include code IF code , code WHILE code , code LOOP code , code REPEAT code , and code CASE code statements, and more. Stored procedures can receive variables, return results or modify variables and return them, depending on how and where the variable is declared. Implementation The exact and correct implementation of stored procedures varies from one database system to another. Most ma ... more details
