HELP.... Images And Pointers
Jun 12, 2006
Hello everyone, I'm in need of help.
I'm using microsoft sql server 2005 along with the microsoft visual studio 2005. I have 2 questions:
1) In the database server, there is an "image" datatype. I need to know how to use that because I need to display images on my webform.
2) I read somewhere that pointers can be used to point the file path. So, is it possible for me to store images / audios in a file and use the database to point to the file path? If it is possible, how can it be done?
Thanks.

hmm ok here is an outline:
I have a view which is a combination of TblHorses and TblOwners has fields:
Form from Horses
StableHands from owners
linked by Horses.OwnedBy = Owners.OwnerID
ok goes through all the horses and creates a number either 0,1,2
based on the formula
Round((int(RSFormUpd("StableHands"))/22) + (rnd * 2),0)
then if the random number = 0 the Form goes down 1 unless is already 1 then stays the same
if = 1 then stays same
if = 2 then form goes up 1 unless it is already 5 then it stays the same
then this is how i coded in asp as i can do asp/vb programming lol but T-SQL is a mystery:
Randomize()
Set RSFormUpd = Server.CreateObject("ADODB.Recordset")
RSFormUpd.open "Select * From ViewWeeklyFormUpdate", Conn, 3, 3
Do While Not RSFormUpd.EOF
UpdForm = Round((int(RSFormUpd("StableHands"))/22) + (rnd * 2),0)
If UpdForm = 0 Then
If int(RSFormUpd("Form")) - 1 = 0 Then
RSFormUpd("Form") = int(RSFormUpd("Form"))
Else
RSFormUpd("Form") = int(RSFormUpd("Form")) - 1
End If
End If
If UpdForm = 1 Then
RSFormUpd("Form") = int(RSFormUpd("Form"))
End If
If UpdForm = 2 Then
If int(RSFormUpd("Form")) + 1 = 6 Then
RSFormUpd("Form") = int(RSFormUpd("Form"))
Else
RSFormUpd("Form") = int(RSFormUpd("Form")) + 1
End If
End If
Response.write RSFormUpd("Form") & " "
RSFormUpd.update
RSFormUpd.movenext
Loop
RSFormUpd.close
Set RSFormUpd = Nothing
Thanks in advance

HiI'm currently having to design a database for a recruitment agencythat's just started up and have one area where I'm a little unsurewhere to go.Basically I've implemented the 'standard' Customer, Contacts tableslinked on CustomerID, and also have CallRecords (for phone calls etcmade to contacts) Linked on ContactID.My difficulty is that they want to be able to store names/details ofpeople looking for work (candidates) BUT these people may also be acontact (i.e. the agency could be dealing with a contact at a companywho is also looking for a new job themselves). They would also like to(naturally) have these candidates details held against 'currentemployer' customer details so there may be situations where a candidateis JUST a candidate (i.e. not currently working and therefore notassociated to a company), OR they may be a candidate AND a contact, andyou may have contacts who are JUST contacts (i.e. not actively lookingfor work at the moment).I'm basically just trying to figure out the options I have for storingthe contact details and candidate details.FYI I need to store the same details for Contacts and Candidates (i.e.name, job title, contact numbers etc) but Candidates require extrainformation to be stored about them (work experience, qualificationsetc).Any help/pointers would REALLY be appreciated!!Thanks in advanceMartin

We currently have a standard star schema warehouse that contains clickstream data from our web server farm. We use a home grown ETL process that is a combination of java code and shell scripts to process these logs on a daily basis. The clickstream data represents both our dimensional data as well as measurements. We are currently processing 22GB of compressed data daily and are currently on a 50% growth rate year over year.
My question is does anyone have experience/pointers on using SSIS to process a stream of data that contains both the dimensions and fact data? Our current architecture pulls out dimensional attributes, processes them separately, and then substitutes the dimensional keys back into the fact stream. I have to believe there is a more efficient way to do this via SSIS.
Any advice would be appreciated.
Thanks

Hi All,
we are just starting to do some testing on sql server EE with dimensional models.....we have had one or two problems we have been able to solve using the new peformance dashboards etc.
However, as is inevitable, we are seeing strange behaviour of a query....in a star join it seems to be doing an eager spool and trying to spool the entire fact table to tempdb....hhmmm....
Rather than ask one question at a time.....we have DBAs who went to classes etc at MSFT and the client is some level of MSFT partner.
Could anyone point me to the best documentation for understanding the optimiser and how to influence it to get it to do the right thing in optimising plans for star joins?
Thanks
Peter

I have an extremely annoying problem when debugging stored procedures in SQL Server 2014 with SSDT or SSMS. When calling a SP thru EXECUTE in Debug mode, 9 out of 10 SPs are traced with a wrong yellow arrow-pointer to the line currently reached.
The offset is between 6 to 15 lines downward. Tracing itself and update of the "Locals"-view works as expected. All SPs contain comments also before the Create Procedure statement. The SP shown when tracing show exactly the same content as the stored SQL in the SSDT project under work incl. Create procedure and all comments.
The picture here show the first line selected after the debugger has traced into the SP. The first line really executed with "Next" will be SET NOCOUNT ON.
If this does not turns out as my fault and some of you would support that, I would like to post this to SQL Connect.

I have a report that i've created that has a picture of the image followed by details relating to the image.
What i'm trying to do if possible is for the user to click on the image and for it to open a new window with the full sized image and then close that image and click on a image relating to another image so they could see that full sized.
Is this possible in Reporting Services? or is there a way in which i could do a similar thing?
Many Thanks

Hi, can someone help me with this problem. I have recently downloaded VWD and have been playing around with it a bit. I was windering how do I add an image file to a SQL database. I have used SQL in the past but I have never store an image in it. I can add text data and so forth, but I need some pointers into adding images to the sql database. I want to be able to store the images and then retrieve them to a GridView. I have the images in an image folder within the website, but I do not know how to input the reference or link to the images in an sql table.
A quick example, say I have a table called Images, with the following info:imgID (int)imgDesc (varchar(max)imgFile (img)imgTitle (varchar(20))
To input this in sql I would write Insert Into Images (imgDesc,imgFile,imgTitle) Values ("Large fishy", "", "The Big Fish") what would I need to put for imgFile?
I would really appreciate if someone can point me in the right direction.

I am trying export images from my SQL server but keep getting the same error:
Error 0xc0208030: Data Flow Task: The data type for "input column "image_full" (105)" is DT_IMAGE, which is not supported. Use DT_TEXT or DT_NTEXT instead and convert the data from, or to, DT_IMAGE using the data conversion component. (SQL Server Import and Export Wizard)
I want to be able to save them locally. The data type is IMAGE. What is the best and easiest way to do this? What format should I be exporting to? Has anyone ever had this problem? Please let me know if you have any help or can point me in the right direction.
Thanks,

Hi everyone. This is my
first post here. I did a quick search and didn't find what I as
looking for, so I'm hoping you all can help me.
I'm working on a project that will allow my company to upload images to
a database and have the website pull the images from the DB. We
are planning to incorporate some type of cacheing, however I'm
skeptical as to if it is really necessary. I imagine that I'm
certianly not the first to do this and I'm wondering if someone can let
me know if I truly should expect a performance hit, or if I shouldn't
really worry about it b/c this is a very common mantra.
Thanks all. I've been pretty vague and haven't explained all of
the details. I can write more, but I'm just looking for
generalizations right now.
Thanks,
HD

Hi,
I am a new VWD user and have been trying to set up a website that allows 1 user to upload images into to SQL Express database and then display them with a variety of other fields.
I have searched the forums, several books and many ASP "training" websites to find out how to do this. Every website seems to teach how to display a list of employees or show photo gallery, but none explains how to upload an image, save it in the appropriate field(s) in the database, and then display it when requested in a Datagrid or Details View using VWD and SQL Express 2005
Can any one give me directions to a solution, or send me a simple solution to this?
The best example of what I need is is a real estate listing, wherethe property for sale has 8 to 10 descriptive fields and 1 to 3 images that are displayed.
Any help would be appreciated.

Hello All!
Can some one give SQL Statement on storing images from disk to the database columns.
Once I store the image how do I test it out that the image is stored correctly?
For example this is what I did
I have a table called table1., field called name
insert into table1(name) values(C:123.bmp)
Is the above statement correct? will it store the file or not?
if it does store them then how do I view them?
Can some one please help me...
Thanks in advance for your help

Hi
Ive recently started working with sql, and am trying to design the db to categorize a multitude of images.
each image falls into their certain categories like "abstract art, surreal art, modern art, classic," and so on.
The way I did it right now, without help or advice, is to create a boolean field for each category, but i have a feeling there might be a simpler and more slim solution for this.
Thanks in advance
