I am reading data from the database where I have a field type of sql.NullString. How can I check if the sql.NullString is empty or not?

You could write a func and pass in the field as an argument. This will allow you to do other things too, like populate a struct…
Sudo code (untested, written in this post but should work.)
func (s sql.NullString) isNull string {
if !s.Valid {
return ""
}
return s.Value
}
