Just keep in mind that, again, LastReqTime is a varchar, so sort order will be alphabetically rather than chronologically. For values representing a correct datetime value, that will work.
To retrieve more than the default 115 rows, I suggest you change the Interactive SQL options (menu Tools item Options...).
My usual changes are
- Category "SQL Anywhere" tab "Results"
-- Maximum number of rows to display: 50000
-- Truncation length: 32750
- Category "Editor" tab "Text Completion" (I don't precisely remember if they're both checked by default)
-- uncheck "Open automatically"
-- uncheck "Complete automatically"
