Answer 1

You have to provide the amount of decimal places for double, eg double (7, 2 ) means your number has a total of 7 digits, whereof 2 are decimal places, just like 10233,95

btw I would strongly recommend to get attuned to use english column names.. there will be one day people who need to understand your DB scheme and do not speak your language

Answer 2

You need to provide decimal places for the double. For eg: berat double( 7 ,2) will work fine

Answer 3

Check out the syntax for declaring columns with double datatype.

you have to indicate the length of the whole number and the length of decimal part

nominal_harga double(10,10)
