In this article I will explain how to read and write BLOBs (Binary Large Objects) data to SQL Server database using C# and VB. BLOBs include files such as Images, PDF, Word or Excel Documents, Audio, Video files.

But before eliminating any code from the previous article, a schema can easily be created by temporarily adding the following lines of code: If you prefer, you can download the NET disconnected paradigm maximizes scalability by minimizing expensive database connections.

The XML schema definition file looks like this in Visual Studio. Tables[1]); // Territories table Add another button to the form as shown below and name it btn Modify Northwind. Update(ds Northwind, "Region"); // C# sql Territories. Because there are no persistent connections, rows aren’t locked on the database server, so optimistic concurrency must be assumed.

The sessions table is a kind of categories table, just have the code and names of the categories, and the conteudosessions is the content of each category.. using (Sql Connection sql Conn = new Sql Connection("Data Source=MSSQLSERVER2008; Initial Catalog=Items_2; Persist Security Info=True; User ID=sa; Password=password")) { string query = "UPDATE tbl_Items SET Name = @Name, [email protected],start = @start, end = @End, Description = @Description where ID = @ID "; Sql Command cmd = new Sql Command(query, sql Conn); cmd.

The Data Set has Central as the original value of the Region Description, but the database contains Local.

The initialization code is simplified to only two lines: ds Northwind. When a schema is available, strongly-typed Data Sets are preferred. A SQL Profiler trace clearly shows what is actually executed on the database server: Now delete a row from the Data Set. Press the Delete key on the keyboard, then click the Write XML button.
