Can't edit/delete reports having a rendering error

[fedor@…]

I was editing a query changing it from the following:

SELECT t.id AS ticket, t.summary, t.type, t.priority, t.status, t.owner, t.time AS created, c1.value AS min, c2.value AS max 
  FROM ticket t, ticket_custom c1, ticket_custom c2 
  WHERE t.id = c1.ticket AND t.id = c2.ticket 
  AND c1.name = 'est_min_hrs' 
  AND c2.name = 'est_max_hrs' 
  AND (t.component LIKE 'xstream' 
  or t.owner LIKE 'henrik@xstream.dk')
  ORDER BY priority, time

into the following:

SELECT t.id AS ticket, t.summary, t.type, t.priority, t.status, 
  t.owner, t.component AS created, c1.value AS min, c2.value AS max 
  FROM ticket t, ticket_custom c1, ticket_custom c2 
  WHERE t.id = c1.ticket AND t.id = c2.ticket 
  AND c1.name = 'est_min_hrs' 
  AND c2.name = 'est_max_hrs' 
  AND (t.component LIKE 'xstream' 
  or t.owner LIKE 'henrik@xstream.dk')
  ORDER BY priority, time

Changing t.time to t.component. For some reason it seems to be interpreting or assuming an integer value, where there is a string value? But that's just my 50 cents.

How to Reproduce

While doing a GET operation on /report/13, Trac issued an internal error.

The t.component AS created part is the problematic one. created, as well as modified and date are used as indicators for a date type. I'll update the TracReports page to make that explicit ... well, it does already (TracReports#Automaticallyformattedcolumns).

So simply pick another alias for t.component.

Thanks, but the error prevents me from editing the report, so I cannot change the alias of the report in question. Of course, I made a new report without the alias, but I cannot get rid of the broken report in the web interface, because of the error message...

[cboos]

That's annoying, you're right.

The usual workaround is to append ?action=edit to the report URL.

Thanks, that helped!

Actually a duplicate of #5806.
