you question is not making any meaning full thing, can you explain it more with your code (if you have any). are you trying to update an existing record where userid=2? also tell me is this a primary key?

Solution 1

If you want to insert record based on some condition:

SQL

If Not Exists(Select * From <tablename> where <filter expression>)
    Insert Into <tablename>(<coulmns>) Values(<values>)
Else
    Update <tablename> Set value=<value> where userid=2

Solution 2

Try to use LINQ query and find the row like this if you are using entity framework:

C#

var db = new DataContext();
var user = db.User.Where(x => x.UserId == 2)

if(user != null)
{
    //Your code here...
}
