I appreciate for any help will come. P.S. most likely i will use insert using a file …

I've posted a bug report here: http://tracker.firebirdsql.org/browse/DNET-540 If someone using Firebird and C# could verify this for me, or shed some light on (other) possible issues, that would be much appreciated. The code works as expected with 2.5.1, but does not with 2.5.2. Note: the sample is built on .NET 3.5 The connection string contains `Enlist=True`. The code is the following (a little different than the one posted in the bug report, but it acts the same): public partial class frmMain : Form { private TransactionScopeOption transactionScopeOption; private TransactionOptions transactionOptions; public frmMain() { InitializeComponent(); transactionScopeOption = TransactionScopeOption.Required; transactionOptions = new …

Hi, I'm using SQL Enterprise Library (Microsoft.Practices.EnterpriseLibrary.Data.Sql) objects and I'm considering using a DbTransaction to execute multiple DbCommand(s) for inserts/updates in one transaction. Let's say these queries take a few minutes to execute, I do not want it to prevent another process from queries the same tables. Considering I do not want to open/close multiple connections and I do not want any "locks" on my database tables is this a good way to go ahead with this? Thanks
