Re: SQL Update ?

This could be simplified a little - just use the case part for the first 3
characters and concat it to the remainder.

update rob/casetest
set testfld =
case
when substr(testfld,1,3)='300'
  then '400'
when substr(testfld,1,3)='310'
  then '410'
...
...
else
  substr(testfld,1,3)
end
|| substr(testfld,4,14)
