asp.net core 2.1 ef core 2.1 date compare not working on server

Question

Hi there I am facing a very strange issue in asp.net core 2.1 I have a query selecting some data for a specific date like

var balances = dbContext.Balances.Where(x => x.BalanceDate.Date == workDay.Date); 

But the query is working on local ENV and even when i connect to remote SQL server. but on Server side it doesn't return any results.

Answer 1

It may have something to do with timezone or milliseconds included in the DateTime type in SQL Server. It can be one of the reasons above, You can do this ( == comparison only)

 var balances = dbContext.Balances.Where(x => 
     x.BalanceDate./*Date.*/Year == workDay/*.Date*/.Year &&
     x.BalanceDate./*Date.*/Month == workDay/*.Date*/.Month &&
     x.BalanceDate./*Date.*/Day == workDay/*.Date*/.Day); 

PS: It's always a good practice to manage/unitialize the timezone offset, or use UTC when dealing with date types.
