內容描述

This unique cookbook contains a wealth of solutions to problems that SQL
programmers face all the time. The recipes inside range from how to perform
simple tasks, like importing external data, to ways of handling issues that are
more complicated, like set algebra. Authors Ales Spetic and Jonathan Gennick,
two authorities with extensive database and SQL programming experience, include
a discussion with each recipe to explain the logic and concepts underlying the
solution. SQL (Structured Query Language) is the closest thing to a
standard query language that currently exists, and Transact-SQL -- a
full-featured programming language that dramatically extends the power of SQL --
is the procedural language of choice for both Microsoft SQL Server and Sybase
SQL Server systems. The Transact-SQL Cookbook is designed so you can use
the recipes directly, as a source of ideas, or as a way to learn a little more
about SQL and what you can do with it. Topics covered include:

Audit logging. In addition to recipes for implementing an audit
log, this chapter also includes recipes for: improving performance where large
log tables are involved; supporting multiple-languages; and simulating server
push.
Hierarchies. Recipes show you how to manipulate hierarchical
data using Transact-SQL.
Importing data. This chapter introduces concepts like
normalization and recipes useful for working with imported data tables.
Sets. Recipes demonstrate different operations, such as how to
find common elements, summarize the data in a set, and find the element in a
set that represents an extreme.
Statistics. This chapter?s recipes show you how to effectively
use SQL for common statistical operations from means and standard deviations
to weighted moving averages.
Temporal data. Recipes demonstrate how to construct queries
against time-based data.
Data Structures. This chapter shows how to manipulate data
structures like stacks, queues, matrices, and arrays.
With an abundance of recipes to help you get your job done more
efficiently, the Transact-SQL Cookbook is sure to become an essential
part of your library.
