20 Part I EXAM PREPARATION T-SQL is an extension of the language defined in the SQL standards published by the International Standards Organization (ISO) and the American National Standards Institute (ANSI). The basic elements of T-SQL are those used to view and edit the data in underlying tables and views. The basis for any database system is the handling of ACD operations which will use these T-SQL operations. ACD is an acronym used in data management for add, change, and delete. These four primary functions for Add (Insert), Change (Alter, Update), Delete, and T-SQL s capability to read and view data (known as Querying the data), are the basis for most SQL Server database activity. In T-SQL you read data with a SELECT statement, add data with an INSERT operation, remove data with DELETE, and change data with UPDATE. T-SQL is presented throughout this blog; for a detailed look into the structure and use of the language go to Chapter 6, Programming SQL Server 2000. Executing a Program Executing T-SQL statements and other commands against a database can be achieved using a variety of techniques. You can develop front-end applications with Visual Basic, Visual C, Access, the Internet, or in combination with other data and programming interfaces. Commands can be executed through ODBC or OLEDB standard libraries connecting to the server from virtually any computer. Statements can be executed directly on the server using the Query Analyzer or OSQL. Query Analyzer Figure 1.1. shows the Query Analyzer, which is your primary tool for executing Transact-SQL code, known as queries. This utility is discussed at great depth throughout the blog. Most of the queries you execute are INSERT queries that add data, DELETE queries that remove data, SELECT queries that retrieve data, and UPDATE queries that change existing data. You can also create database objects such as views and indexes.

STRUCTURED QUERY LANGUAGE (SQL) . Be familiar with the programming environment and industry-standard coding language. SQL is an industry-standard programming language used to insert, retrieve, modify, and delete data in a relational database. SQL also contains statements for defining and administering the objects in a database. SQL is the language supported by almost all database systems, and is the subject of published industry standards. SQL Server 2000 uses a version of the SQL language called Transact- SQL, or T-SQL. Transact-SQL Language Elements Transact-SQL is the language containing the commands used to administer SQL Server, to create and manage all objects in SQL Server, and to insert, retrieve, modify, and delete all data in tables.

Chapter 1 INTRODUCTION TO SQL SERVER 2000 17 gations. An indexed view provides for a technique where fast access to data is enabled (indexing), associated with data display definitions (views), and where the result set of the view is materialized and stored and indexed in the database. Indexed views are covered fully in Chapter 7. SQL Server 2000 introduces three new data types bigint, sql_variant, and table that are supported for variables and are the return types for user-defined functions. Data Types are covered in full in Chapter 2, Data Modeling. INSTEAD OF triggers are executed rather than the triggering action (for example, INSERT, UPDATE, DELETE). They can also be defined on views, in which case they greatly extend the types of updates a view can support. AFTER triggers fire after the triggering action. SQL Server 2000 introduces the capability to specify which AFTER triggers fire first and last. Triggers are covered fully in Chapter 8, Constraints, Defaults, and Triggers. Cascading actions enable you to control the actions SQL Server 2000 takes when deleting or changing data. If you attempt to update or delete a key to which existing foreign keys point, cascading actions will dictate the effects on the associated records. This is controlled by the new ON DELETE and ON UPDATE clauses in the REFERENCES clause of the CREATE TABLE and ALTER TABLE statements. Cascading Referential Integrity is covered fully in Chapter 3, Physical Database Design. SQL Server 2000 includes support for most collations supported in earlier versions of SQL Server, and introduces a new set of collations based on Windows collations. You can now specify collations at the database level or at the column level. Collations are covered fully in Chapter 3, Physical Database Design. SQL Server 2000 supports running multiple instances of the relational database engine on the same computer. Each computer can run one instance of the relational database engine from SQL Server version 6.5 or 7.0, along with one or more instances of the database engine from SQL Server 2000. Connecting to Multiple Instances of SQL Server is covered fully in Chapter 2, Data Modeling. SQL Server 2000 can partition tables horizontally across several servers, and define a distributed partitioned view on each member server so that it appears as if a full copy of the original table is stored on each server. Groups of servers running SQL Server that
