Hi,
In such scenario you should use some KeyValue pair in the database. Instead of creating number of columns for the information, create only two column. one for
Key and another with it's
Value.
By default your table have some default value. And each time you can update the information from the table.
You should use this scenario only when you do not have any option to save the information other then database.
--------------------
key | value
--------------------
username | abc
otherinfo| infovalue
nextinfo | nextvalue
---------------------
Many people may not accept this methodology but this is my personal opinion
Thanks
