Hi,

you can create a table and add columns to it when the need arises, however that would be bad design for several reasons; the table structure would be unpredictable, it would probably be very sparse (most fields remain empty), and processing it could be quite cumbersome.

I'd suggest you use a very simple table with essentially two columns, say my_key and my_value, both string.

Your example
["name_data1", "123"],
["name_data2", "456"]"
["name_data3", "789"]

would then sit in three rows, exactly as you described it yourself!

Of course you might want to also provide a primary key, a created timestamp, and maybe a creator field.

If the data entered is related, you need some kind of parent field or group field, so you can indicate how the records belong together.

I certainly advise you to create some processing code before deciding your final table structure, so you don't paint yourself into a corner.

Smile | :)
