Should I commit or rollback a read transaction?

Question

I have a read query that I execute within a transaction so that I can specify the isolation level. Once the query is complete, what should I do?

• Commit the tr

Just a side note, but you can also write that code like this:

using (IDbConnection connection = ConnectionFactory.CreateConnection())
using (IDbTransaction transaction = connection.BeginTransaction(IsolationLevel.ReadUncommitted))
using (IDbCommand command = connection.CreateCommand())
{
    command.Transaction = transaction;
    command.CommandText = "SELECT * FROM SomeTable";
    using (IDataReader reader = command.ExecuteReader())
    {
        // Do something useful
    }
    // To commit, or not to commit?
}

And if you re-structure things just a little bit you might be able to move the using block for the IDataReader up to the top as well.
