Escape Character in Anonymous Block Report Definition

[peterputt]

Hi

I'm trying to create a report to get the calls per hour for certain application...  My query is running fine, but if I put it into an Anonymous Block, CUIC interprets "::DATETIME" as a parameter:

select startdatetime::DATETIME HOUR TO HOUR AS CallHour, count(*) from contactcalldetail where
startdatetime between :START and :END and
applicationname = :APP
group by CallHour
order by CallHour

How can I escape the ":"?

Thanks in advance

Peter
