I have a simple SQL statement.
Select distinct value from tablename where value not like '%TEST%'
How do I write this in Linq to SQL syntax.
I tried the below statement but it doesnt seem to work.
var p = (from c in tablename where !(c.value.ToUpper().Contains("%TEST%"))
select c.Value).Distinct().ToList()
The problem is the "%" - you're looking for things which literally don't contain "%TEST%" which would probably be everything. I think you mean:
var p = (from c in tablename
where !c.Value.ToUpper().Contains("TEST")
select c.Value).Distinct().ToList()
If you were stuck with a pattern for sql to match, you could use SqlMethods.Like
string pattern = "%TEST%";
...
from c in tablename
where !SqlMethods.Like(c.Value, pattern)
select c
