Regarding blob data in mysql query RRS feed

  • Question

  • Hi,

    Can anyone please guide me.I have written the below query and i display the result in a gridview.But there is part of data with attachements is there a way to exclude that data from the query?

    select distinct t.id,t.Subject,t.Status,Trim('<br />' from cast(Content as char)) as content,a.created as Created,u.name
    from rt.Tickets t
    inner join rt.Transactions tr on tr.objecttype ='RT::Ticket' and tr.ObjectId = t.id
    inner join rt.Attachments a on  a.transactionId = tr.id
    inner join rt.Users u on u.id = a.creator
    where status in ('pending') and name != 'RT_System' and Content not like '%WordDocument%'
    and Content not like '%word%' and Content not like '%div%'
    and Content not like '%http%'
    and Content is not null

    when i run the query i get the below data:

    id             subject                              status             content                                  created                              name
    123          UPS media card failed        pending          service request required        2012-08-29 16:40:14        abc
    123          path loss                            pending                                                        2012-03-12 15:03:48         xyz

    here in the above "content" this is a blob field and in the 2nd row it is the attachment i get empty when i run the query but when i display on the grid i get the below

    id    -   123

      Subject    -   UPS media card failed

    12/03/2012 15:03:48  PM Alarm Cleared.&nbsp; They confirmed the following &quot;<span style="color:#1F497D">This unit has been checked and there is nothing wrong or abnormal noticed locally. The 48V DC is being supplied from the power adapter and link activity on the radio unit, WAP and the media converter are all just normal.</span> &quot;&nbsp; Unfortunately, it is grey on the NMS, but topology is all green.

  • This is a SQL Server forum and I am afraid that my MySQL experience is limited.

    In SQL Server you cannot skip a column for some rows and include it for others, but you can control what appears in that column's value.  For example, using T-SQL syntax:

    SELECT t.id, ..., 
        CASE
            WHEN DATALENGTH (content) <= 50 THEN content
            ELSE '*** Data too large ***'
        END AS content,
        ...
        

    Also, there are several MySQL forums where you could ask, including: http://forums.mysql.com/
