Storing Pictures In Database
Sep 13, 2007
Hy, could someone help me in this:
In design mode, i want to put pictures in database. I made column named
pics, and its type as image. How can I put pictures or some address of these
pictures in that column, or i maybe need to put pictures in Add_Data folder
and make reference from there, or what I need to do?
could someone explain me that process of putting at least one picture in
database, I'm using Microsoft SQL Server 2005
thanks everyone

I'm constructing an image gallery for my site and was wondering how to store the pictures in the database? Would the best way to do it, by storing the link instead of the image in the database?
How would I use the insert and select with it? :confused:

Hey all,
Just starting to investigate this. I need to store digital pictures in my database for use in claims and disputes. I have played a bit with the image datatype but notice that one picture takes up 1Mb as a TIFF and 3Mb as a JPEG. Does anybody work with this stuff and if you do what is the best picture format to use in regards to keeping clarity but minimizing size used in the db. Is there any load conversion routines that would shrink the size of the file.
Any suggestions or comments on this topic are appreciated.
Thx. Kelsey

Hello there,I just want to ask if storing data in dbase is much better than storing it in the file system? Because for one, i am currenlty developing my thesis which uploads a blob.doc file to a web server (currently i'm using the localhost of ASP.NET) then retrieves it from the local hostAlso i want to know if im right at this, the localhost of ASP.NET is the same as the one of a natural web server on the net? Because i'm just thinking of uploading and downloading the files from a web server. Although our thesis defense didn't require us to really upload it on the net, we were advised to use a localhost on our PC's. I'll be just using my local server Is it ok to just use a web server for storing files than a database?

I have a system that basically stores a database within a database (I'msure lots have you have done this before in some form or another).At the end of the day, I'm storing the actual data generically in acolumn of type nvarchar(4000), but I want to add support for unlimitedtext. I want to do this in a smart fashion. Right now I am leaningtowards putting 2 nullable Value fields:ValueLong ntext nullableValueShort nvarchar(4000) nullableand dynamically storing the info in one or the other depending on thesize. ASP.NET does this exact very thing in it's Session State model;look at the ASPStateTempSessions table. This table has both aSessionItemShort of type varbinary (7000) and a SessionItemLong of typeImage.My question is, is it better to user varbinary (7000) and Image? I'mthinking maybe I should go down this path, simply because ASP.NET does,but I don't really know why. Does anyone know what would be the benifitof using varbinary and Image datatypes? If it's just to allow saving ofbinary data, then I don't really need that right now (and I don't thinkASP.NET does either). Are there any other reasons?thanks,dave

Is it better to have users that upload pictures have them saved to SQL server or to a folder? I have a site where users enter things that they own (and each item has a unique id) and now I would like to add the functionality to add a picture. I am sure I should use the fileUpload control, but should this save to a folder created for each user or to the SQL record itself? Or possibly a separate SQL table just for pictures?Thanks for the help.

best way to store questionnaire data in a database.Since different questionnairs have different questions and formats i.e dropdown, radio, checkboxes etc building such a database model becomes highly complex.
I've read that if data schema is complex and higly variable it may be better to use an xml document and store that in a databse. However I dont quite understand how you store xml to a database. Do you simply store the entire structure in something like a nvarchar column or is there some other way to store xml to a database.
If you store the entire structure to the databse then how do you query the content to generate reports.
example xml:
Code:
<survey>
<meta>
<id>sample</id>
</meta>
<questions>
<question id="1" type="singlechoice" page="1">
[code]...

Does anyone currently do this. I want to store an audit history for changes made in the database through our web application.
I would like some kind of history table structure. I would be interested to see if anyone else has done this and what your structure looks like.

I have a bit of a dilema, that maybe someone can give a reccomendation on. I have a vb app that will calculate a duration that a process runs in hours:minutes:seconds. My question is should I store this in the database as a date/time field or calculate total seconds and store it as an integer field? I will be using this field for basic summing calculations in the future. Thanks for any help.

An odd question from me, I know, but this time, I assure you a twist.
I have a group that wants to store images in either a database or a file share, in order to make a certain website able to run on a load balanced web farm. These images are around 1KB each in size, and have a lifespan of exactly one use (think of graphs). I went a-googling, and found no shortage of articles that say "don't do it, but here's how you can do it", but I did not find any real hard statements as to why to not do it. Needless to say, this is hurting the case for not putting these images in the database. I have found an article that says images over 8KB will have worse performance, but I can not use that factoid here. For the moment, I have the developers leaning toward the fileshare, because they will be writing transaction logs all day, which will be more work than the fileshare needs to do....I think. The best I can do, is cut the text/image datatype overhead, and have them create the table as varbinary(2000), but even then, I don't like the look of the idea.
Anyone out there have good articles/whitepapers that detail the differences between writing single-use images to a fileshare vs. a SQL database? <baiting=blatant>Failing that, do any of the Microsoft development team have an opinion?</baiting>
Alternatively, what is the general opinion of keeping session state information in a database (because I bet that will be my next battle). I see .NET includes a session state server, but not being a programmer, I can not create an opbjective test.

Hey I currently have a foreach loop container working which scans a folder, loops through the files in this folder and then moves them to a new folder.
At the same time I also do an SQL insert into a table logging the details of the transfer.
What I would like to do next is to store the actual PDF in binary in my DB (varbinary format). How would I go about this ?

i use a teltonika t-modem gsm modem..
it's quite new actually and it is connected to my PC thru a usb port..
my problem now is that
i can,t seem to get the hang in storing received messages in
my SQL database..
the code goes like this..
a receive button is clicked to generate an instance
where all SMS sent to my sim card would then be accessed by my gsm modem..
private void btnReceive_Click(object sender, EventArgs e)
{
ListViewItem Component;
Cursor c = Cursor.Current;
Cursor.Current = Cursors.WaitCursor;
listView1.Items.Clear();
btnReceive.Enabled = false;
objGsmIn.Device = cmbDevice.SelectedItem.ToString();
objGsmIn.LogFile = txtLogging.Text;
if (cmbDeviceSpeed.SelectedIndex == 0)
{
objGsmIn.DeviceSpeed = 0;
}
else
{
objGsmIn.DeviceSpeed = System.Int32.Parse(cmbDeviceSpeed.Text);
}
objGsmIn.Storage = fMsgStore.MsgStorage;
if (fMsgStore.DelMsg == true)
{//deletes your message after receiving
objGsmIn.DeleteAfterReceive = 1;
}
objGsmIn.Receive(); //this checks your new incoming messages
if (objGsmIn.LastError == 0)
{
objGsmIn.GetFirstMessage();
while (objGsmIn.LastError == 0)
{
//continously receive all messages..
Component = listView1.Items.Add(objGsmIn.MessageSender);
Component.SubItems.Add(objGsmIn.MessageData);
objGsmIn.GetNextMessage();
}
txtResults.Text = "Messages Successfully Received..";
}
else
{
//error in message receiving process..
txtResults.Text = "Error " + objGsmIn.LastError + "(" + objGsmIn.GetErrorDescription(objGsmIn.LastError) + ")";
}
btnReceive.Enabled = true;
Cursor.Current = c;
}
now my problem is that i cant figure out where i would place my stored procedure
in storing those messages to my database..
the problem is that..
if i place my stored procedure on the 1st "IF" statement..
it will only save my 1st incoming message..
but another thing is that if i put it under my "WHILE" statement..
dont you think that it will continiously loop?
meaning to say that the next tym i tried to access all my received messages
it would definitely store all the previously read messages again to my database..
which then creates multiple copies of my previously stored messages again and again
well i hope you get the gist of what i mean..
its quite complicated to explain..
but then again thanks a lot for taking notice on my post regarding this..
thanks!!^_^
another thing..i used the active xperts c# application in order to
create this application..

Dear All,
I am new to dot not. I'm using vbdot net 2003 with crystal reports that bundled with vs2003 for creating catalogues for our company. We have furniture pictures in access db. In design time I have added picture field to the crystal reports and ticked the cangrow property so the picture can fit into its true aspect ratio. but some pictures grow into full page of the report. unticking 'cangrow' property also makes trouble as the picture does't streches well. I want 6 pictures to appear in each page by 2 column wise(how to add 2 columns in a report?). We want to automate printing catalogues of chosen furnitures by our customers. I'm struck with this problem for past few days.
can anyone help with sample code please?
Thanks a lot in advance

Hi,I have a table which I need to store times in. What is the best way of doing this? The only way I can think of so far is to save the times as a datetime such as '1/1/1900 03:00 PM' then format the date as "hh:mm tt" so that the day isn't displayed. Is this the best method?Thanks,Curt.
