Purpose of The Z SQL Methods User’s Guide
This guide was created to provide an overview of the attributes of ZSQL Methods. The format of the guide provides step by step instructions on how to publish relational data on the Web. With Zope examples and explanations, the user creates SQL queries using DTML.
•     The Zope object database can be queried like relational databases using DTML commands.
•     You can query existing relational databases within Zope to provide web based content management.
•     Relational database queries results are first-class Zope objects.
•     The Z SQL methods support the integration of relational data with the Zope object system.
•     Database Connections explain how to manage and create connections to external databases.
•     Instructions to create search interfaces between Zope and database queries are explored.

This guide will take you through creating, testing and debugging, query templates, and editing of SQL database methods. SQL Methods support a number of specialized tags for inserting values or comparisons into SQL source, an explanation of these various tags are provided in this guide.

This manual describes the features of the DB Audit Performance Add-on for Microsoft SQL Server, including how to use the install and configure the add-on, use graphical user interface and performance audit and analysis reports.

When to Use the Performance Auditing Add-on

If you are not satisfied with your SQL Server performance, you can add additional CPU or improve other hardware characteristics to boost overall performance. This seems to be obvious, the more CPUs your server has, the faster it can perform. However, the standard edition of SQL Server can support up to 4 CPUs only. For support for more than 4 CPUs, and up to 32 CPUs when using Windows 2000 or 2003 Datacenter Server, you will need to run SQL Server 2000 or 2005 Enterprise Edition.

A cheaper alternative to purchasing expensive hardware and software upgrades is tuning SQL Server configuration and applications and making them run more efficient.

SQL injection is yet another common vulnerability that is the result of lax input validation. Unlike cross-site scripting vulnerabilities that are ultimately directed at your site’s visitors, SQL injection is an attack on the site itself—in particular its database.

The goal of SQL injection is to insert arbitrary data, most often a database query, into a string that’s eventually executed by the database. The insidious query may attempt any number of actions, from retrieving alternate data, to modifying or removing information from the database.

To demonstrate the problem, consider this excerpt:
// supposed input
$name = “ilia’; DELETE FROM users;”;
mysql_query(“SELECT * FROM users WHERE name=’{$name}’”);

The function call is supposed to retrieve a record from the users table where the name column matches the name specified by the user. Under normal circumstances, $name would only contain alphanumeric characters and perhaps spaces, such as the string ilia. But here, by appending an entirely new query to $name, the call to the database turns into disaster: the injected DELETE query removes all records from users.

About this book

This book describes how to plan, set up, maintain, and monitor a data replication environment using DB2 replication, which is the focus of the book. This book contains the guidance and reference information for the SQL replication component that is introduced in IBM DB2 Information Integrator Introduction to Replication and Event Publishing.

SQL replication, also referred to as DB2 replication, is a type of replication that uses SQL to replicate data between systems. The term is used to differentiate this type of replication from Q replication, which replicates data through message queues.

Who should read this book

This paper provides information for software developers about how to configure an SQL-SMS connection in the Ozeki NG Gateway to send and receive SMS messages using a database server (All major database servers are supported: Oracle, MSSQL, MySQL, Sybase, Informatix, etc.) If you set up this functionality, you will be able to send an SMS message by simply executing an SQL Insert statement in your database server. This paper gives you all the necessary information to achieve this. You can learn how to add an SQL user in the configuration file and how to configure sending and receiving. We also provide links to explanations of different database server connection settings.

The Ozeki NG SMS Gateway supports database connectivity. Database connectivity allows you to send or receive SMS messages using simple SQL queries. The way this works is illustrated in Figure 1.
