revDataFromQuery and DELETE FROM

[Ralph DiMola]

Using the revExecuteSQL returns the number of deleted/inserted/updated rows
in the result. Then the test is:

If the result is not a number then
--Error code here
End if

I try to always check my results and trigger a "panic" that shows the
returned error when a query fails.

For this one, I just take an exact match of "revdberr," as a success code.
So

if theRes <> "revdberr" then
panic "bad delete in someFunction" & cr & cr & theRes end if

If you're *not* checking your return codes, you're asking for pain . . .
