INTEGRATION WITH VISUAL STUDIO 2008
ODT is fully integrated with Visual Studio
2008 and Visual Studio 2005. This
integration starts in the Microsoft Server
Explorer tree control.
The Oracle Developer Tools for Visual Studio is fully integrated with Visual Studio
2008 and Visual Studio 2005. This integration starts in the Microsoft Server
Explorer tree control. This tree control makes it easy to browse database schema
objects which are represented as nodes in the Server Explorer tree. Each schema
object node offers context menus which allow operations on that node. For
example, a table node offers a “Retrieve Data” menu item, which opens up the
Oracle Data Window. It also offers a “Design” menu item which opens up the
Oracle Table Designer for easy creation or modification of an Oracle table.
Similarly, the many other various Oracle schema types have item specific menus.
The Visual Studio Properties Window shows metadata for any Oracle Database
schema node that is currently selected. For example, selecting a table column node
will show the Oracle data type of that column in the Properties Window.

Automatic .NET Code Generation
In Visual Studio, code generation starts
with the Data Sources window. These data
sources can then be dragged and dropped
onto the design surface to immediately
create runnable .NET code.
For rapid application development, ODT is also fully integrated with Visual
Studio’s automatic code generation features. In Visual Studio, code generation
starts with the Data Sources window, where data sources are created and defined
via the Data Source Configuration Wizard. These data sources can then be dragged
and dropped onto the design surface to immediately create runnable .NET code
which accesses an Oracle Database. This code can be easily and visually wired up
to widgets on the design surface (such as a Gridview control) resulting in a
runnable application with very little coding required.
To aid in customizing the code that is auto generated, Visual Studio designers and
wizards associated with automatic code generation are also fully supported, for
example the Table Adapter Configuration Wizard and Dataset Designer. These
designers make it easy to customize the application and to create master-detail
relationships.
Code Generation for Microsoft Office and ASP.NET
Developers utilizing Microsoft Visual Studio
Tools for Office (VSTO) can rapidly
generate Microsoft Office based
applications by simply dragging and
dropping an Oracle Datasource onto an
Excel spreadsheet or Microsoft Word
application.
Developers utilizing Microsoft Visual Studio Tools for Office (VSTO) can rapidly
generate Microsoft Office based applications by simply dragging and dropping an
Oracle Datasource onto an Excel spreadsheet or Microsoft Word application. For
example, an Oracle Data Source for the HR.EMPLOYEES table can be created
via the Microsoft Data Source Wizard in Visual Studio. After dragging this data
source and dropping it on the Excel design surface, the table data will
automatically be displayed in the Excel spreadsheet when it is loaded and it can
then interact with other Excel macros.
Automatic code generation for ASP.NET web applications is also supported and is
described below.
ASP.NET WEB DEVELOPER SUPPORT
Integration with ASP.NET automatic code generation means that web developers
can create working ASP.NET web applications with very little or no .NET or SQL
coding required. Dragging a widget (such as the Gridview control) onto the Visual
Studio Web Site design surface launches the Microsoft SQL Data Source Wizard.
This wizard automatically generates the required code for data access and then
wires this code to the GridView control. Building and running the web application
launches a built-in web server within Visual Studio. A web browser is also
automatically launched to enable the execution and debugging of the running
application.

The ASP.NET Providers for Oracle, (a separately installable product included with
the ODT download) makes it easy for Oracle web application developers to take
advantage of Visual Studio web controls (for example, the Login control or
Sitemap control). Developers can use these controls to rapidly generate web
applications without writing code and store the corresponding control data in
Oracle. Using the Microsoft ASP.NET Website Administration tool, the web
server can easily be configured to store the web site data (such as login
authentication information or web site data caching) into Oracle Database with
just a few clicks of the mouse.
ORACLE DATABASE PROJECT WITH SOURCE CONTROL SUPPORT
The new Oracle Database Project provides a simple and convenient way to
manage the SQL scripts associated with a .NET application. Scripts can be
New 11g Features in Oracle Developer Tools for Visual Studio
Page 6
checked in and out of any MSSCCI compliant source control server (for example,
Microsoft Source Safe, Microsoft Team Foundation Server, or Subversion) via
simple menu items in the Database Project window. Scripts can also be
automatically generated directly from Oracle Database and put into the Oracle
Database Project via the “Create Script to Database Project” menu item in the
Server Explorer tree control.
Source control support makes it easy to collaborate with other team members and
simplifies the deployment of the SQL Scripts associated with a .NET application
ODT provides a simple and convenient way
to manage the SQL scripts associated with
a .NET application. Scripts can be
automatically generated, edited, executed
and checked in and out of any source
control server (for example, Microsoft
Source Safe, Microsoft Team Foundation
Server, or Subversion).
Figure 3: Oracle Database Project with source control support
ORACLE SQL SCRIPT EDITOR
Double clicking on any script file in the Oracle Database Project opens the script
in the Oracle SQL Editor. The editor is file based and features syntax coloring and
integration with the Oracle Online Help documentation. The Oracle Database SQL
New 11g Features in Oracle Developer Tools for Visual Studio
Page 7
Reference, PL/SQL User’s Guide and Reference and the Error Messages, manual are all
indexed and included inside of the Visual Studio help system. The extensive
keyword indexing of the online help means that highlighting any keyword and
pressing the “F1” help key launches the online help to the topic desired.
The SQL Script can also be easily executed via a context menu item in the editor.
BUILT IN SUPPORT FOR EXECUTING SQL*PLUS SCRIPTS
SQL scripts can be run either directly from
the Visual Studio menu (“Run SQL*Plus
Script” menu item), from a context menu
(“Run”) from the Oracle SQL Script editor,
or directly from the Oracle Database
Project.
Oracle Developer Tools for Visual Studio adds a SQL*Plus compliant SQL Script
execution engine to Visual Studio. This means that scripts can be run either
directly from the Visual Studio menu (“Run SQL*Plus Script” menu item), from a
context menu (“Run”) from the Oracle SQL Script editor, or directly from the
Oracle Database Project. The SQL script will execute in precisely the same way as
it would if run from the SQL*Plus command line, with any output going to the
built-in Oracle Output window.
Figure 4: Run SQL*Plus Script dialog
INTEGRATION WITH MICROSOFT QUERY DESIGNER
Microsoft Query Designer makes it simple to design SQL Queries using a
sophisticated GUI design surface. Table relationships can be set up by dragging
and dropping, queries can be tested, and the final SQL statement representing the
design is generated. These designers are integrated throughout Visual Studio such
as in the Dataset Designer. Wherever a SQL statement is required, the Query
Designer can be easily launched.

NEW DESIGNER FOR GRANTING/REVOKING SCHEMA PRIVILEGES
The Oracle Developer Tools for Visual Studio includes a new designer that makes
it easy to grant and revoke privileges on schema objects to other users or roles.
Simply launch the designer from the “Privileges” context menu item in Server
Explorer and then choose which privileges to grant and to which user or role to
grant them to. Of course, the user can only grant privileges to the degree
permitted by the Oracle DBA.

NEW USER-DEFINED TYPE SUPPORT
Server Explorer can now be used to
explore all aspects of UDT’s in Oracle. A
“User Defined Types” node is included to
allow users to view, create or edit type
definitions.
Oracle user-defined types (UDTs) are fully supported and integrated throughout
Visual Studio. This feature is highly sought after by developers who use UDTs
extensively, including Oracle Spatial users and developers who use VARRAY and
Nested Table types in stored procedures and functions.
Server Explorer can now be used to explore all aspects of UDT’s in Oracle. A
“User Defined Types” node is included to allow users to view, create or edit type
definitions using new graphical UDT designers. Oracle table columns and stored
procedure parameters which use UDT types can also be explored.
When creating new tables or procedures, the Oracle Table Designer and the
Oracle Stored Procedure/Stored Function Wizard include all UDT’s in a drop
down list of potential data types. The Oracle Data Window now displays table data
that includes UDTs as output. The data is displayed in an XML format.
UDT Custom Class Code Generation Wizard
A powerful UDT Custom Class wizard is provided to make access to UDT data
from .NET code (with the Oracle Data Provider for .NET ) easy and fast. A single
click from a menu item in the User-Defined Types Server Explorer node launches
the wizard. When the wizard completes, the generated code is added to the user’s
.NET project. This .NET code defines the UDT in C# or VB.NET code and
makes accessing the UDT data as easy as accessing any other data type.
In conjunction with the other automatic code generation features discussed in the
first section of this paper, an application can then be rapidly created that utilizes
UDTs with almost no coding required.
A powerful UDT Custom Class wizard is
provided to make access to UDT data from
C# or VB.NET code easy and fast and an
application can be rapidly created that
utilizes UDTs with almost no coding
required.

IMPORT TABLE WIZARD
Developers often need to import tables and data into their test database. These
tables may need to be imported from another Oracle Database or from other
New 11g Features in Oracle Developer Tools for Visual Studio
Page 10
heterogeneous data sources such as Microsoft SQL Server, Microsoft Access or
Excel spreadsheets. The Import Table Wizard makes this easy and requires only a
few clicks. The imported table structure can be easily customizable via the wizard.
Any third party database or file format for which there is installed an ADO.NET
2.0 compliant data provider can act as a data source.
The Import Table Wizard makes it easy to
import tables and table data from another
Oracle Database or from other data
sources such as Microsoft SQL Server,
Microsoft Access and Excel spreadsheets.

ADDITIONAL ENHANCEMENTS
This release includes new features to enhance the user experience of ODT users.
Query Window Enhancements – Explain Plan, Auto-Commit
The Oracle Query Window makes it easy to execute single or multiple SQL
statements and view the output in a grid or in text format. The SQL text can be
typed in by hand, or can be created automatically by dragging and dropping from
tables listed in Server Explorer.
The Query Window is now enhanced to include the ability to execute an “Explain
Plan” to determine the Oracle Database execution plan of a particular query. This
plan can then be cut and pasted into an email, instant messenger session, or text
document and provided to interested parties such as the Oracle DBA.
Additionally, an auto-commit toggle button makes it easy to enable or disable autocommit if so desired.

Various options pages have been added to allow the user to customize their user
experience. This includes options to control the displayed schema objects in Server
Explorer, the maximum number of rows to be fetched by the Oracle Data
Window, as well as controlling the metadata to returned by the Explain Plan
feature of Query Window.
