• Why is TransactionScope using a distributed transaction when I am only using LinqToSql and Ado.Net

  - by Ian Ringrose

  We are having problems on one machine, with the error message: "MSDTC on server XXX is unavailable." The code is using a TransactionScope to wrap some LingToSql database code; there is also some raw Ado.net inside of the transaction. As only a single sql database (2005) is being accessed, why is a distributed transaction being used at all? (I don’t wish to know how to enable MSDTC, as the code needs to work on the server with their current setup)

• Convert Unix Epoch Time to Seconds in SQL or .NET

  - by user293249

  First let me thank you all for your help. What I need is a function that takes in a EPOCH time stamp, like 1452.235687 and converts it to a readable timestamp like '01-01-1970 00:00:00'. More specifically I only need the time not the date. If at all possible I would prefer a .NET function instead of a SQL stored procedure. However an SQL stored procedure would work fine as well. Thank you again,
