  Need help with SQL to LINQ conversion

  Nov 12, 2018 03:12 PM|bootzilla|LINK

  I'm trying to convert this sql statement to linq and need some assistance:

  Select  
  	ul.[id] ,
  	ul.[name] ,
  	ul.[create_date] ,
  	ul.[last_update] ,
  	ul.[created_by] ,
  	ul.[last_updated_by] ,
  	ul.[deleted_by] ,
  	ul.[LOCATIONNAME] ,
  	ul.[BILLCODECUSTNUMLIST] ,
  	ul.[ALLOWRESTORATIONSUBMISSION] ,
  	ul.[COMPANYNUMBER] ,
  	ul.[ALLOWITEMORDERING] ,
  	ul.[ITEMORDEREMAIL] ,
  	ul.[GUID] 
  FROM USERLOCATION ul,
  MULITCUSTOMERACCESS mca
  where mca.USERID = 'Value'
  and mca.LOCATIONNAME = ul.locationname
  and ul.locationname = 'Value'

  Here is my linq code (usr is WINS_USER table):

  billcodelist = String.Join(",", dc.USERLOCATIONs.Where(f => f.LOCATIONNAME == usr.LOCATION || dc.MULITCUSTOMERACCESSes.Where(d => d.USERID == usr.Name).Select(d => d.LOCATIONNAME).Contains(f.LOCATIONNAME)).Select(f => f.BILLCODECUSTNUMLIST).ToArray());

  I don't know how to combine the two tables in the FROM clause together using LINQ.

  How do I convert that sql to linq, what am I doing incorrectly?

  How did the T-SQL even work without a T-SQL  Join on the two tables? 

  A Join on mca.LOCATIONNAME equals ul.locationname Where mca.UserId = value

  Your Linq is nowhere in the ball park in ever working, at least I have never seen such a Linq statement. using a String.Join()

  Linq 101 shows you how to use a Linq Join.

  https://code.msdn.microsoft.com/101-LINQ-Samples-3fb9811b

  Here is an example of T-SQL Join.

  You can't share what you figured out? Maybe, someone else may face a similar problem that you post could help.

  It was a completely different issue then what I posted on here. Had nothing to do with what I posted on here. I basically had to create a new linq query from a different form in the solution.
