• How to handle when SSRS does not automatically update fields based on database query?

  - by badpanda

  So I am trying to change the number of fields in my dataset in SSRS and the refresh button is not picking up the added field from the SQL server. The query is definitely returning the correct data, as I have double checked in the server engine itself.

• node to traverse cannot be null (Hibernate SQL)

  - by tiswas

  I'm performing a SQL query through hibernate, which looks like: SELECT thi FROM track_history_items thi JOIN artists art ON thi.artist_id = art.id WHERE thi.type = "TrackBroadcast" GROUP BY art.name ORDER thi.createdAt DESC but I'm getting the message that 'Node to traverse cannot be null!'. Anyone know what could be causing this? --EDIT-- I'm pretty sure that this problem is being caused by the possibility of artist_id to be null. However, I can't prevent this, so can I just skip the rows track_history_item rows which have a null artist_id?

• compiling a linq to sql query

  - by frenchie

  Hi, I have queries that are built like this: public static List<MyObjectModel> GetData (int MyParam) { using (DataModel MyModelDC = new DataModel()) { var MyQuery = from.... select MyObjectModel { ...} } return new List<MyObjectModel> (MyQuery) } } It seems that using compiled linq-to-sql queries are about as fast as stored procedures and so the goal is to convert these queries into compiled queries. What's the syntax for this? Thanks.
