Strange behavior of Entity Framework query

Question

Below query yielded no results even when there was matching record in the DB.

• Even the query generated will yield the result when executed in DB.
• Also, query yields the result when "order by" is added to the query.
• No changes in the query parameters.
• Same query works for dev database, yields no result in QA database.
• There is no change in the QA database compared to Dev.

Answer 1

I think you need to add filter for the ADMINGROUP

var currentDept = (from d in dbContext.TBLZLISTDEPTs
where d.ADMINGROUP != null
select new 
{
   d.ADMINGROUP
}).FirstOrDefault();
