I have created a data table with columns [ UserName , PhoneNumber , Email , TimeSlot ].
I’m trying to retrieve data by taking phonenumber as user-input ! but before showing data I want to check if there are some element in response or not.
if there are some data in response they I’ll show it , else give a message that no data available with this phone number.
how to set this logic if(data present) show result
else show no data available.
thank You !
