fields must be been fill in 15 characters. if a user fill in less than that how to make a warning or message they have to fill in 15 characters.

Answer 1

NO,

but

when you are creating database we must select data type as varchar .

If you selected char type it occupy total size with null .

If you selected varchar type it will store how much string length at the dynamic time .

Answer 2

You need to setup a validate function
