Output of SELECT and similar files is sent to result.txt. All else is
sent to stderr. If you wish to see everything, redirect output (Linux
example: isql -i update.sql -o result.txt > result.txt 2>&1)

Even better is to check the result of isql. AFAIR, if it returns zero
then command is executed without errors, and non-zero means that there
has been an error).
