Basics of Procedure Builder 19 Introduction to Oracle: SQL and PL/SQL Using Procedure Builder19Ć2 Objectives Basics of Procedure Builder 19Ć3 Objectives A key feature of procedural programming is the ability to create and debug code quickly and easily. Procedure Builder provides all of the functionality necessary for you to successfully develop and debug PL/SQL programs. This lesson enables you to manipulate PL/SQL code using Procedure Builder. At the end of this lesson, you should be able to D Identify the advantages of developing and debugging PL/SQL programs in Procedure Builder. D Manage program units by using the Object Navigator. D Execute program units and SQL statements by using the PL/SQL Interpreter. D Define and compile procedures by using the Program Unit editor. D Define and compile database procedures by using the Stored Program Unit editor. D Set a breakpoint to suspend program execution. D Control the execution of an interrupted PL/SQL program unit. D Test possible solutions by changing variables and procedures at runtime. Introduction to Oracle: SQL and PL/SQL Using Procedure Builder19Ć4 Basics of Procedure Builder 19Ć5 Overview Procedure Builder is an integrated development environment. It provides for the editing, compiling, testing, and debugging of PL/SQL programs within a single tool. In addition, it enables developers to drag and drop program units between the client and server. You can improve your application development efforts by using the features available in Procedure Builder. You will become familiar with these features by learning about each component’s function. Once you are familiar with the Procedure Builder environment, you will cover the PL/SQL syntax. Procedure Builder Features Component Description Object Navigator Manage PL/SQL constructs. Perform debug actions. PL/SQL Interpreter Debug PL/SQL code. Evaluate PL/SQL code in real time. Program Unit Editor Create and edit PL/SQL source code. Stored Program Unit Editor Create and edit server-side PL/SQL source code. Database Trigger Editor Create and edit database triggers. For more information, see Oracle Procedure Builder Developer’s Guide, Release 1.5. Introduction to Oracle: SQL and PL/SQL Using Procedure Builder19Ć6 Procedural Programming Capabilities Basics of Procedure Builder 19Ć7 Oracle Procedure Builder Capabilities Procedure Builder is an integrated, interactive environment that you can use to create, execute, and debug PL/SQL programs. Using Procedure Builder, you can build portable database programs quickly and easily. Integrated PL/SQL Development Environment D Create and edit subprograms. D Compile subprograms to perform syntactical error checking. D Test subprograms. D Debug subprograms. Unified ClientĆServer PL/SQL Development D Create database triggers. D Create stored procedures and move them to the client to debug. D Build and edit client-side libraries. D Create client-side program units and move them to the server.

The Interpreter The Interpreter is the central debugging workspace of Procedure Builder. It is a two-pane window where you display, debug, and run PL/SQL program units. It also interactively supports the evaluation of PL/SQL constructs, SQL commands, and Procedure Builder commands. The Program Unit Editor The easiest and most common place to enter PL/SQL source code is in the Program Unit editor. You can use it to edit, compile, and browse warning and error messages during application development. The Stored Program Unit Editor The Stored Program Unit editor is a GUI environment for editing server-side packages and subprograms. The compile operation submits the source text to the server-side PL/SQL compiler. To debug server-side program units you can drag a copy of the program unit to the client side using the Object Navigator. The Database Trigger Editor The Database Trigger editor is a GUI environment for editing database triggers. The compile operation submits the source text to the server-side PL/SQL compiler.
