Agenda  Database and SQL Development  Schema Modeling and Offline Editing  PL/SQL Development and Debugging  Questions and Answers

Schema Modeling  “Design-capture” existing schema objects  Visually design tables and relationships  Generate DDL from diagram – SQL File – Directly to database – Reconcile with database

Offline Tables  Import objects from an existing database  Create and edit table definitions while disconnected  Generate DDL to create or alter tables  Reconcile changes with database

D E M O N S T R A T I O N Schema Modeling

Agenda  Database and SQL Development  Schema Modeling and Offline Editing  PL/SQL Development and Debugging  Questions and Answers

Editing and Compiling PL/SQL  Comprehensive editor features – Bookmarks – Macros – Code Templates – Search and Replace – Syntax Highlighting – Etc  PL/SQL Code Insight  Synchronized Structure window  Errors reported in Log window

Running PL/SQL  Run Procedures, Functions, and Packages – DBMS_OUTPUT – Function return values – OUT parameters  Run PL/SQL dialog – Specify run target – Shows parameter information – Generates editable PL/SQL block for populating parameters

Debugging PL/SQL  Supported with Oracle8 i and later – Uses JDWP implementation starting with Oracle9 i Release 2  Control program execution – Step Into, Step Over, Run to Cursor, etc  Inspect and modify variables – Tooltips in Code Editor  Configure breakpoint conditions

PL/SQL Debugging Requirements  Compiled with debug information – JDeveloper “Database Connections” preferences panel – ALTER SESSION SET PLSQL_DEBUG = TRUE – ALTER COMPILE DEBUG  Oracle8 i and Oracle9 i specifics – CREATE ANY PROCEDURE (debugging other schemas)  Oracle9 i Release 2 specifics – DEBUG ANY PROCEDURE DEBUG CONNECT SESSION – Compiled in Interpreted (not Native) mode

Additional PL/SQL Debugger Features with Oracle 9.2  Debug Java stored procedures  Seamless debugging between server-side Java and PL/SQL  Inspect elements of PL/SQL Collections (Tables, Records, etc)  Remotely debug PL/SQL calls from any client

Remotely Debugging PL/SQL Client Application 1: Listen 2: Attach 3: Execute Database Session JDeveloper

Remotely Debugging PL/SQL: Explicit Calls 1.Start the debugger listener in JDeveloper (Listen for JPDA) 2.Modify the client code to attach to the debugger listener from the database session: DBMS_DEBUG_JDWP.CONNECT_TCP (‘host’, port); 3.Initiate procedure call from the same database session, for example: EXEC my_procedure; 4.Modify the client code to terminate the connection with the debug listener: DBMS_DEBUG_JDWP.DISCONNECT_TCP();

Remotely Debugging PL/SQL: Implicit Calls  Two-tier OCI applications – Set environment variable set ora_debug_jdwp = host12.acme.com;port=4040 – OCI layer transparently calls the server-side PL/SQL to connect with the debugger listener  Web mod_plsql applications – Create a UI form to set a cookie in the browser – Pass the hostname and port to owa_debug package – owa_debug transparently calls the server-side PL/SQL to connect with the debugger listener for each subsequent page requested by that browser

D E M O N S T R A T I O N PL/SQL Development

Summary  JDeveloper is a complete development environment for SQL and PL/SQL in addition to Java and XML
