var query = from h in dbk.Employee_table
where h.City.StartsWith("L") && h.City.Contains("n")
dbk = It is the DataContext object (With the help of this object, we can get access to any table in the respective database)
The above query will search employee table city column which starts with a Capital 'L', than some character, than 'n' and than the rest of the name.
Equivalent sql statement will be :-
SELECT Emp_ID, City, ...
WHERE City LIKE [L%]
AND City LIKE [%n%]
Thanks and Regards
