通过Ado.Net 3.5和C＃多次插入SQL Server 2008

Question

I have a collection of data. I need to insert these records into SQL Server 2008. I also need to maintain transaction, so that if one insert fails, I need to rollback all the changes done.

Can some one suggest a best way to do this? I use .Net 3.5.

Answer 1

You need to create a transaction using your SqlConnection object's BeginTransaction method. This will return an SqlTransaction object that you need to keep track of.

When all of your items have been successfully inserted into the database, you will call Commit on the transaction object.

If an exception is encountered during your processing, you will need to call Rollback on the transaction object.

Roughly speaking, the code is:

SqlConnection conn;
// Create and open your connection here

SqlTransaction trans = conn.BeginTransaction();
try {
   // Perform your inserts

   trans.Commit();
} catch(Exception ex) {
   trans.Rollback();

   // Report the exception
}

Depending of wheather you are using ADO.NET/plain SQL you can use bulk insert, or, if you are using Linq-to-SQL you can try using LINQ Entity Data Reader to insert large amounts of data at once.

By using bulk insert each batch is copied to the server as one transaction. If this fails, SQL Server commits or rolls back the transaction for every batch.
