Database and SQL Development Schema Modeling and Offline Editing PL/SQL Development and Debugging Questions and Answers
Connection Manager
Create and test connections with a wizard Store often-used connections Import and export connections Reuse connections throughout lifecycle
– Database, PL/SQL Development– Application Development– Deployment
Additional connection types– Application Server, WebDAV Server, SOAP Server,
Oracle9i SCM Server, UDDI Registry
Browsing the Database
View schema objects from the Navigator– Tables (Indexes, Columns, Constraints, Data)– Views– Synonyms– PL/SQL subprograms– Oracle Objects– Materialized Views (Snapshots)– Java Resources
User-defined filters at all levels
Creating Database Objects
Create schema objects– PL/SQL subprograms– Tables– Views– Triggers
SQL Worksheet
Execute any valid SQL statement Browse query results Access previous statements from SQL History Fetch rows incrementally
Tuning SQL Statements
Get the Explain Plan for any SQL statement

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

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 Oracle8i and later– Uses JDWP implementation starting with
Oracle9i 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 <PROG_UNIT> COMPILE DEBUG
Oracle8i and Oracle9i specifics– CREATE ANY PROCEDURE (debugging other schemas)
Oracle9i 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: Listen1: Listen
2: Attach2: Attach
3: Execute3: 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
