) In this article, I'll explain the basic yet essential processes involved in building a C# or Visual Basic .NET application that uses an Oracle database, including: You will have the opportunity to apply what you have learned in three practice labs, ranging in difficulty from the relatively simple to the more complex. NET applications for Oracle Database with Visual Studio 2005/2008, the experience with Visual Studio 2010 is very similar.Visual object editors are available complete with help to guide you through the editing process.Standard data views are also available to help you view your data.NET data providers optimized for an Oracle database. NET specifically, or to the Oracle Database Documentation Library for general information about Oracle Database. NET application that retrieves data from the Oracle database. Data Access was chosen here, but you can chose any ODP. Visual Basic/C# Statements After adding references, it is standard practice to add Visual Basic Imports statements or C# using statements.Oracle and Microsoft make their Oracle data providers available for free. Later, we’ll see how to perform error handling with ODP. Technically, these statements are not required, but they do allow you to refer to database objects without using lengthy, fully qualified names.
Database objects (tables, views, stored routines, triggers, indexes, etc) can be created, altered, or dropped directly inside Server Explorer.
However, the clear text approach is undesirable from a security perspective. NET application code is only marginally more secure than the clear text source code files. NET DLL and EXE files and view the original clear text contents. Close and Dispose Either the connection object's Close or the Dispose method should be called to close the connection to the database.
(Encryption is in fact the appropriate solution, but that subject would be a quite lengthy digression from our discussion here.) Next, you must instantiate a connection object from the connection class. The Dispose method calls the Close method implicitly. To String()) Finally ' In a real application, put cleanup code here.
Stored routines (both with and without parameters) can also be queried.
My SQL for Visual Studio allows full debugging of stored routines.
