Storing Pictures In Image Data Type
Apr 17, 2001
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

1. How can I upload new pictures into the database through the browser.
2. Can you describe how the new picture of the product would be uploaded into the database.
3. How do you handle different formats that pictures come in gif, tif, jpeg,
etc.
4. How can you say that SQL server does support images well, because on
microsoft site they loaded up the satellite data of the earth into sqlserver
which is only picture data

I am using the 3-tiered architecture design (presentation, business laws, and data acess layers). I am stuck on how to send the image the user selects in the upload file control to the BLL and then to the DAL because the DAL does all the inserts into the database. I would like to be able to check the file type in the BLL to make sure the file being uploaded is indeed a picture. Is there a way I can send the location of the file to the BLL, check the filetype, then upload the file and have the DAL insert the image into the database? I have seen examples where people use streams to upload the file directly from their presentation layer, but I would like to keep everything seperated in the three classes if possible. I also wasn't sure what variable type the image would be in the function in the BLL that receive the image from the PL. If there are any examples or tips anyone can give me that would be appreciated.

I have a very large array of floating point numbers which I am tryingtostore in an image type field. I am using the dataset class todirectly enter the data but am having trouble trying to get this typeinto the image field. I guess the question is how do I get a largefloating point array into an image (byte)field of a database using thedataset class for new row entry.Thanks

Hi,
I'm storing thumbnails in SQL CE and accessing them from my WPF application. The save seems to take place ok and there's binary data in the image field however when it comes back out it appears to be corrupted somehow. Can someone have a look at the code below and verify I'm doing the conversion correctly before storing in my image field? Thanks!
- Roland
Code Snippet
private byte[] GetArrayOfPixels(BitmapSource bitmapsource)
{
Int32 stride = bitmapsource.PixelWidth * bitmapsource.Format.BitsPerPixel / 8;
Int32 ByteSize = stride * bitmapsource.PixelHeight * bitmapsource.Format.BitsPerPixel / 8;
byte[] arrayofpixel = new byte[ByteSize];
bitmapsource.CopyPixels(arrayofpixel, stride, 0);
return arrayofpixel;
}
//I assign the byte array returned to my datatable like so:
MediaAsset asset = new MediaAsset(){
Thumbnail =
new Binary(GetArrayOfPixels(Thumbnail as BitmapSource));
}
//then I insert it into my tables collection
myDB.MediaAssets.InsertOnSubmit(asset);
//and submit the change
myDB.SubmitChanges();
Am I not getting that pixel array correctly for storage?
Thanks for the help!

Let's say a user profile page on a website contains a description about a car that the user wants to sell. The user could try to be wise and write something very short like "buy my car" or the user could write a very lengthy description of his car to convince the buyer to make the purchase.
Or somebody creates a thread in a forum or replies to a topic (much like what we do here).
In these instances, what is the most efficient manner of storing the high-character content in these examples with SQL Server 2005? Keep in mind that a user could make a 2-character post like "OK" or could write a long reply or create a huge profile. So the data type has to be efficient and flexible. Judging from the list of available types in my Express 2005, I would guess the varchar(MAX) or the text data types could be used. Or would I use some other data type?
TIA.

I have been asked to write a piece of code that will insert an image object into a database using a stored procedure and the Microsoft Enterprise Library. Has anyone done this before? Do you have any code examples about how to update a database with an image datatype that needs to be chunked, etc...
In this instance, I need to open up a word document and save the contents as an image in a database.

hi, i'm a student doing my final year project. during the user requirements stage, my client proposed storing all files (.doc, .jpg, .mp3) into the sql database. i found out that the way to do this is to write the files as binary data in order to store them in the database. my concern is will this data storage overload the database server? i read somewhere that the retrieval of data as binary data is the same as retrieving text. but the estimation of users is around 27,000.. if i'm not wrong, the sql database server should be MS SQL Server 2005, or at least 2003.

I have a page for inventory price entry that I have used for a while. Now I need to add a checkbox for whether or not the price includes shipping. I added the checkbox to the form and had it posting 'True' or 'False' to the database as nchar(10) data type. When the gridview pulls up the data, I have the Item Template like this, so it shows a disabled checkbox either checked or not: <asp:CheckBox ID="CheckBox2" runat="server" Checked='<%# Convert.ToBoolean(Eval("Shipping")) %>' Enabled="False" /> This works fine for displaying the values, but I copied the checkbox to the Edit Item Template, but did not disabled this one. At first, I didn't change the databindings, leaving it Convert.ToBoolean(Eval("Shipping")), which allowed me to go into Edit mode, change the checkbox, then click update. At which point it would return to it's original state (meaning Update wasn't actually updating). However if I change the databindings, then the page won't display. I checked the SQL statement, and sure enough, it has theUpdateCommand="UPDATE [PartsTable] ... SET [Shipping] = @Shipping... WHERE [PartID] = @original_PartIDAfter fiddling with the sql statement, now I get Object cannot be cast from DBNull to other types. I think that means that the checkbox is sending a null value to the database.Any insight as to how to get this to work is much appreciated. Thanks in advance.

The ERP manufacturer used an image data type to store large text data fields. I am trying to move these data types from one database to another database using either Sql Queries or MS Access. I can cast them as an 8000 char varchar to read them directly but have no luck importing into these image data fields.
Access and Crystal are not able to read these fields directly.
Any suggestions? Most information about these fields has to do with loading files but I am just moving data.
Thanks,
Ray

Anyone can help regarding this?

I'm using ODBC to interface a Microsoft SQL Server 2000. One of theoperations involves placing files within BLOBs. I'm using the imagedata type for this purpose. Most of the time this works okey, but whentrying to add a 21,3 MB file I get an error. The error code is 22001,which means "String right-truncation". But why? Does this mean thatthe field cannot accepts BLOBs with this size?

Hi
I am currently working on an application that uses a stored procedure to retrieve data from a database and then display it in a web page. My problem is that some of the data in the database will be images, I am currently putting in test data to test my code/procedures my problem is how do I put in test data for images, when I am finished I am going to add an admin section that will allow me to add images that way but how do I go about adding them to the database until then? I have set the field to the image data type but have no idea how to relate this to an image on my server?
Thanks, Adam

Hello, I am trying to store pictures in an Image data type column of my MsSQL table from PHP, or even SQL Query Analyzer for that matter. In PHP I use the bin2hex() function to get the HEX equivilent of the picture, I'm sure everyone knows that when you convert a Binary file to HEX, the file size is doubled. When I try to insert the HEX file into my table with a query like:
INSERT INTO PicTable (fileType, fileData) VALUES ('jpg', 0x47494638396164014100f70000000000ffffff2f2f2fe800020c0c0ce....)
MsSQL will store EXACTLY HALF of the file. The byte count of the stored HEX data and original Binary data is exactly the same, so when I try to extract the file and display it, in a browser window for instance, I can see exactly half of the image. I have tried everything I can think of to fix this, but I am at a loss. Does anyone know of anything that would cause this strange behavior. I have no problems at all doing this with MySQL's BLOB data type. Thanks in advance for any help.

Hi,
I've a column col1 of image data type in table1. I would like to copy the data from col1 to another image column col2 in table2. Before moving the value, checking has to be done to specify which col1 data from table1 is needed and the destination has to be checked too.
Example: insert into col2
(select col1 from table1 where table1_id =5)
where table2_id =6
Hence bcp wouldn't work. Can anyone suggest me a way to do it. I tried using writetext but then, i've to get data from col1 in a variable, which is not possible. Any suggestions would be very helpful.
Thanks in advance.
Ramya.
