Solution 2

Try:

C#

string query = "select ID from Emp where city='abc' OR pincode=123456 OR ";
int index = query.LastIndexOf("OR");
if (index >= 0)
   {
   query = query.Substring(0, index);
   }

Simply properly build your query without the final OR when you build it!

Typically, I would recommand you to build your query in C# as it is probably easier to do and also validate the query.

Anyway, remember that you should never build a query from string specified by the user as it open security holes.
