Hello all,

I want to write a linq to sql query. the query that I want to implement is:

SQL

SELECT lbl.STATUS, lbl.TYPE 
FROM LABELS as lbl
JOIN RECORDS as rec ON lbl.ID = rec.LABELID
WHERE rec.STATUS == 0 OR rec.STATUS == 1 or rec.STATUS == 2

I have tried

C#

var trackingQuery = from t in dbContext.LABELS
                    from r in dbContext.RECORDS.Where(a => a.recStatus.Value = 0 || a.recStatus.Value = 1 || a.recStatus.Value = 2)
                    select new
                    {
                      t.STATUS,
                      t.TYPE
                    }

I am having "Operator '||' cannot be applied to operands of type 'int' and 'int'" this error but couldnt resolve this. Can someone help me out? Thanks

I have applied a.rmaStatus.Value = 0. The error message is similar but this time instead of nullable int it is replaced with just int. "Operator '||' cannot be applied to operands of type 'int' and 'int'".

Solution 2

You need to use == instead of =

e.g

C#

var trackingQuery = from t in dbContext.LABELS
                    from r in dbContext.RECORDS.Where(a => a.recStatus.Value == 0 || a.recStatus.Value == 1 || a.recStatus.Value == 2)
                    select new
                    {
                      t.STATUS,
                      t.TYPE
                    }
