  - by BahaiResearch.com

  In .NET land I would normally query the database and populate a generic List kind of collection. Then the app would use this. In Android land I have been reading about DB access and use in apps.

• Is it possible to use SQL XML to insert, and get output from each record?

  - by nbolton

  I would like to perform a SQL XML insert (on MSSQL), and in this case I need to insert a list of files into the DB (this is simple enough). However, there's an auto generated PK column (ID), and I need the ID for each newly created filename without performing a 2nd query. Is this possible?

• Passing around a SqlConnection

  - by Chris

  I have created a TransactionScope and within the scope various items are created and updated in the database. During this process I make a lot of calls to the database. Originally I opened a SqlConnection in the beginning of the TransactionScope and passed it around to any function that made a DB call then I closed the connection after all the calls are made and before the transaction commits. Is it better to do this or to open and close a connection for each call?

• Can I write a test without any assert in it ?

  - by stratwine

  Hi, I'd like to know if it is "ok" to write a test without any "assert" in it. So the test would fail only when an exception / error has occured. Eg: like a test which has a simple select query, to ensure that the database configuration is right. So when I change some db-configuration, I re-run this test and check if the configuration is right. ? Thanks!
