Date Restriction No Longer Working. Please help!

Question

Hi! I wrote the following script that restricted just fine for dates prior to 10/1/9. So for example, s19.DataContent >= '9/1/9' and s19.DataContent <= DATEADD(day,1,'9/30/9') works perfectly but s19.DataContent >= '10/1/9' and s19.DataContent <= DATEADD(day,1,'10/30/9') does not. I'm assuming it has something to do with how the date is stored but I can't figure out. Any help is greatly appreciated!

Ok - the vendor provided a completely generic table with all content datatypes as nvarchar. that is unfortunate. Please post some dataContent values for customerFieldID = 19 so we can see if the value can be directly converted to datetime. If they can be then you can say,

convert(datetime, s19.dataContent) >= '2009-10-01'

otherwise you'll have to manipulate the string to something that can be converted to datetime. Another thing I'd suggest is replace all those JOINs to different instances of the same table with something like this:

select  s1.TicketID            
       ,max(case d.customFieldID = 3 then d.dataContent) end as Requester            
       ,max(case d.customFieldID = 5 then d.dataContent) end as Department            
       ,max(case d.customFieldID = 7 then d.dataContent) end as Program            
       --etc            
from   (--get all tickets that satisfy the date criteria            
       select ticketID            
       from   st_CustomDataFieldsinTickets            
       where  customFieldID = 19            
       and    convert(datetime, dataContent) >= '2009-10-01'            
       and    convert(datetime, dataContent) <= DATEADD(day,1,'2009-10-30')            
       ) s1            
--get all other values in one table            
join   st_CustomDataFieldsinTickets d            
       on d.ticketid = s1.ticketID            
where  d.customFieldID in (3,5,7) --,10,11,12,14,16,17,18,19,20)            
group by st.TicketID

EDIT: Assuming your comment is accurate and that first two parts ("199 19.") are not part of the dataContent value it looks like one of your values is not well formed. It is missing a "/" separator. You would need to exclude those value or clean them up. That is one of the problems of storing data in untyped columns.

select dataContent            
       ,convert(datetime, dataContent) as dataContentConverted            
from   (            
       select convert(nvarchar(255), '10/1/2009 09:45 AM') as dataContent            
       union all select '10/5/2009 7:20 AM'             
       union all select '10/5/2009 8:20 AM'            
       --union all select '19 10/6/2009 7:00 AM'            
       union all select '10/6/2009 8:00 AM'            
       union all select '10/6/2009 8:10 AM'            
       union all select '10/6/2009 4:30 PM'            
       union all select '10/8/2009 11:45 PM'            
       ) d

So, if one row of the dataContent looks like this : 192 19 10/1/2009 09:45 AM

You could do:

convert(datetime,substring(dataContent,8,len(dataContent))) >= '2009-10-01'

If this doesn't work, can you post any that are different to this format?
