Child Parent Transactions roll back

Question

I have a scenario in which I have to process multiple .sQL files, every file contains 3-4 insert or Update queries, now when any query in a file fails I do ro

Answer 1

Keep all insert, update queries in a try{..}catch(..){..} and if any exception occurs, in the catch roll the db transaction back.

     private void InsertFoo(SqlTransaction txn, string fooName)
     {
         using (var cmd = txn.Connection.CreateCommand())
         {
             try
             {
                 do your process here...
                 cmd.Commit();
             }
             catch(Exception ex)
             {
                cmd.Rollback();
             }
         }
     }
