How to manage multiple transactions in SQL Server 2005

Question

I'm developing a desktop application in C# with a SQL Server 2005 backend.

I want to insert rows into two tables, in table1 one row will be saved and in table2 more than 100 rows will save at a time.

I want that while saving is going on and between it if power fails or due to any reason program terminates then that incomplete transaction should not saved in the database; but if transaction completes successfully, then it should be saved to the database.

I'm using Connection.BeginTransaction() methods

 clsData dSave = new clsData();
 dSave.Open(); // 
 System.Data.SqlClient.SqlTransaction tr = dSave.Connection.BeginTransaction();

clsData is a class in which some variables are declared like SqlConnection, SqlCommand, SqlAdapter, a var called Connection is declared in this class and a method Open() is declared in this class which opens connection.

Difficulty is that after some 10-20 commands, tr.Connection suddenly becomes null, where as my connnection is still open.

Anybody can help me about this problem.

Answer 1

• Use a stored procedure call
• Use XML or table valued parameters to pass in the data
• Manage the transaction in SQL Server

Don't make 100+ call to the database server in a client side transaction
