What you say simply doesn't happen. Either the query will insert a record, or you will get an exception.

There is an error in your query, though. There shouldn't be apostrophes around the @CustAdd parameter, that will make the database interpret that as a literal string, not a parameter:

string query = "insert into Customer(CustomerName,CustomerAddress,PhoneNo) values (@CustNm,@CustAdd,@Ph)";

I'm not certain how the database would react, but you would either get an exception telling you that you have a parameter that is never used in the query, or it would insert a record with the value @CustAdd as the address.
