in reply to DBI Update dynamically

Every user having a different number of fields seems strange and goes against the basic principles of relational database design.

A "kludgey" solution however could be as follows:

  • SELECT the record you want to update and put this record's data into an array.
  • Update this array with the new data.
  • DELETE this record.
  • INSERT a new record with the updated data from the array.

A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
