In SQL Anywhere 16 Sybase Central, where does the Event Properties "Next scheduled time:" value come from? The displayed value seems to be the previous time rather than the next time. I can't find any related column in the catalog colums. |

It seems likely you may have already figured out where this info is coming from but here's the answer with links for others. The SCJView uses the DB_EXTENDED_PROPERTY( ) function to display this. The portion of the select list in the query used to extract that looks like this: cast("DB_EXTENDED_PROPERTY"('NextScheduleTime',"E"."event_name") as timestamp)
as "next_schedule_time"
correlated on event_name. I don't see the previous time behavior so that might need to be looked into. If you are working with a 10.0.0 or early 10.0.1 server it may be possible you might see a missed schedule that way. Engineering Change #480547 was fixed in 10.0.1 bld#3562 and all more recent releases. The issue there was if the schedule's 'start time' included milliseconds, it could fail to 'fire'. Otherwise, see what happens when you revert/change the public/dba timestamp_format. If that has any impact you might want to compare your results to the behavior describe in Engineering Change 625647.

That was supposed to be a link inside of a code formatted section. Failing that I have corrected the original answer.
