Hi friends,
I am writing a sql query for updating value based on the two input values.
The value should be updated only when two inputs are matched.
Please correct this query if i made a mistake.

SQL

update Student_Contact_details 
set Contact_name = @contactname, 
    Contact_Relation = @contactrelation, 
    Phone_number = @phonenumber, 
    Alternative_phone_number = @alternativenumber, 
    Email_id=@emailid, 
    StreetAddress=@streetaddress, 
    City=@city, 
    State=@state, 
    Country=@country, 
    Zipcode=@zipcode, 
    Update_date_time=@updatedatetime

And how exactly are we to know "if i made a mistake"? Does it do what you want? Does it pass validation? Do you get an error?

Your query will successfully execute. go ahead. Be confident about what you are doing, if you have any problem regarding what you are doing then ask for help. Its not a good habbit to ask to check your problem, no one knows for what you are doing this.

Thanks

"Please correct this query if i made a mistake" isn't a question.You need to tell whether it works right or wrong? Your code is OK,then you need to see whether it works or not.Any question?See this..
