I'm not 100% sure what the old procedure did again, but this is probably
what you want:
(row-for-each*
(lambda (a b c)
(printf "Got a = ~A, b = ~A, c = ~A\n" a b c))
(query conn "SELECT a, b, c FROM foo"))
If you prefer to get the arguments in a list, use the version
without a star:
(row-for-each
(lambda (tuple)
(printf "Got tuple = ~A\n" tuple))
(query conn "SELECT a, b, c FROM foo"))
If the docs are unclear, I'd appreciate it if you can help me to
improve them.
Cheers,
Peter
