You collect the data, update the database, then query the database.

If you want to store multiple checkbox values in a single column then you should turn the collection of checkboxes into a binary number

eg.
CHKBOX1 = 0
CHKBOX2 = 1
CHKBOX4 = 1
CHKBOX8 = 1

The number to store in the Db would then be 14 (i.e. 1*8 + 1*4 + 1*2 + 0*1)

To set the values from the database you need to reverse the process - i.e. take the number 14
get the binary representation and set the checkboxes appropriately.
