Chapter 1 Introduction 1.1 OVERVIEW Interactive SQL (often referred to throughout this manual as ISQL) is a utility supplied with c- treeSQL that lets you issue SQL statements directly from a terminal and see results displayed at the terminal. You can use interactive SQL to: • Learn how SQL statements work • Test and prototype SQL statements to be embedded in programs • Modify an existing database with data definition statements • Perform ad-hoc queries and generate formatted reports with speci

Chapter 2 Quick Tour 2.1 INTRODUCTORY TUTORIAL iSQL_Tutorial1.sql This introductory tutorial will rapidly take you through the basic use of the powerful interactive SQL (iSQL) database interface. iSQL is a full featured command line client side query tool useful for submitting ad hoc SQL statements to a Server. Likewise the tool provides ample output formatting capabilities. By no means does this introduction cover the full scope, detail, or flexibility that iSQL offers. It does however

ISQL and Tools 2.1.2 Define In this case define consists of the CREATE TABLE statement. This is done in a single iSQL statement in which specific fields are defined. Upon successful creation of the table, the changes made to the database by this transaction are made permanent by executing the COMMIT WORK statement. The following SQL syntax provides the functionality for the define phase: • CREATE TABLE — Create a table. • COMMIT WORK — Make changes permanent. Below is the interactive SQL

ISQL and Tools 2.2 RELATIONAL MODEL AND INDEXING TUTORIAL iSQL_Tutorial2.sql This intermediate tutorial will advance the concepts introduced in the first tutorial by expanding the number of tables and building a relational model. This tutorial will walk you through defining an index for each table, demonstrating the power of indexes in a rela- tional model using a few simple API calls. This tutorial operates on the assumption that the database named 'myDatabase', already exists. Please ref

Quick Tour 2.3 LOCKING TUTORIAL iSQL_Tutorial3.sql This tutorial will introduce the concept of locking. The function- ality for this tutorial focuses on adding records, then updating a single record to the customer master table. From the iSQL utility the script will be parsed and passed to the server. The script com- pletes without "committing" the update. This leaves the updated record locked. The user will launch another instance of the Inter- active SQL utility in another window which
