SELECT *
FROM MY_TABLE
WHERE VALUE_1 IN (1, 2, 3)

Answer 1

For your updated question, you could also use a switch-statement.

switch (myvalue)
{
   case 1:
   case 2:
   case 3: 
      // your code goes here
  break;
}

Answer 2

The in keyword in C# is for the foreach statement and for LINQ query expressions. There is no functionality equivalent to SQL's in operator in C# per se, but LINQ offers similar functionality with Contains().

var list = {1, 2, 3}
var filtered = (
    from item in items
    where list.Contains(item)
    select item).ToArray().
