Avoid Caching Image Datatype
Jul 23, 2005
Hi all,
I have a database with 40GB of binary objects stored in image columns
in two tables.
Our database server is also used for another 15 databases.
SQL Server caches the image-column, causing the cache-hit-ratio to
dramatically decrease, since fetching a couple of binaries from the
image-column uses up the
memory, and throws other cached objects out of the cache.
Is there a way, and could someone tell me how, to avoid caching of
specific
columns/tables?
Regards

Hello all,
I have a peculiar problem. We are using VS-2005,SSRS-2005,SqlServer-2005. Our front end is Windows forms and we are communicating with SSRS through WebServices protocol. Through WebServices we are generating dynamic parameters based on the report and were able to show them on the Win form screen.
The previously entered values are being retained even though we delete the existing one. I am unable to figure out the cause of it.
Please help......

Hi,
I'm having some troubles getting a chart drillthrough to work correctly in the MS Report Viewer. I'm using VB.NET 2.0 in a WebApplication.
Here's what happening:
I build the report with drillthrough functionnality in a chart. When I preview it, or look at it on the report web interface (http://localhost/Reports) it works perfectly. However, once I open it in my WebApplication with the MS' ReportViewer it starts to get ugly.
The report loads the first drillpath correctly. Once I click on a bar to drill to the next drillpath, the report seems to load the data, but the image doesn't represent that as it is the old one. I can tell that the correct data is loaded since the imagemap has changed when I mouseover the chart (links are not on bars, but where they are supposed to be on the second image).
In an attempt to be clearer, here's a step by step:
1- Create the report and the drillthrough functionnality.
2- Preview it in the report builder, works perfectly.
3- Test it in the report manager (http://localhost/Reports), works perfectly.
---
4- Load it in the MS' ReportViewer in my WebApplication, the first image in the drillpath loads correctly.
5- Click on the chart to get to the next drillpath, report reload with what seems to be the good data, but the image isn't refreshed.
So, is it possible to force an image to be reloaded with Reporting Services?
Thanks

Hi!! Im psyche34. :confused:
I was confused on what to do on a Image datatype.
I had created a dummy database name "DUMMY_DB"
On that database I created a table name TB1 having a fields name: Picture as image
Text as text
through queries I insert a value to each field but the problem I can't insert a value on column Picture.
What value would I insert on the field "Picture"
Is it the directory where the picture was stored??
Please help Im badly needed to know. Thank you

I read somewhere that I can use BULK INSERT with a format file.
Can someone suggest how to BCP in siccesfully or How does the format file looks like for this kind of task?. I am using SQL Server 2000.

Is there any method to find out the size of an image datatype currently in the database. For example I have 2 tables that contain the same image, but the archive table is not displaying the same as the main. I am thinking the image file was corrupted somehow but don't know how to check this out.
Any ideas?

I have a table with an IMAGE datatype. Without using xp_cmdshell and bcp, is it possible to get this image to disk? We do have the OLE procedures enabled so I can use those to create in instance of the Scripting.FileSystemObject and write to disk but how do I convert the image datatype to something I can store on disk and it actually be a readable format? If it helps, we only store this particular field in JPEG format in the database.

I have a column called "Image" in a table that stores all the user information. Image holds the data for the user's badge photo. I'm currently working on a project to move some of the data from the users table to more relevant tables. With the SQL script I wrote to copy the data into the new tables the image data appears to not have been transferred correctly. I had tried storing the image data into a variable of type varbinary(8000) before inserting it back in. Is there a certain datatype that must be used to store the data when reading from a column of data type "image" and then inserting it into another column of data type "image" without getting truncation or corruption of the data?

We used SSIS to move data from a table in SQL 2000 which had a column with the image datatype to a column in a table in SQL 2005 that has a datatype of varbinary(max). No errors were produced from the SSIS package.
There were a number of records where the DATALENGTH of the column with the image datatype was greater than 8000. Was the data truncated for these records?
This is probably a very elementary question, but I am not familiar with the application or the data.
Below is the source table in SQL 2000 and a select count(*) ...
CREATE TABLE [dbo].[LSCHANNELCUTDATA](
[UIDCHANNELCUT] [numeric](19, 0) NOT NULL,
[VALUECODES] [image] NULL,
...
selectcount(*)
from[LSCHANNELCUTDATA]
whereDATALENGTH ( [VALUECODES] )> 8000

Hi everyone.
I have a field that is image datatype. That table is included in a snapshot replication. When I try to update that field - on the publication server, which is the same as distributor server - if the image is too big (in size), an error message appears. When I try to update with images that has less size it works. If I take out the subscriptions, it works for every image size.
Any ideas?

I have been fighting with this all day. If you can point me in the right direction I'd appreiciate it. I need to load about 500 jpg files into a table. The table has 3 columns an "ID", "Filename" which has the filename of the jpg in it already, but not the unc path, and a ("Photo" Image Datatype)column which is not populated yet. I need to store the Image file in the photo field so that I can run reports in reporting services and so on and so forth. I am not sure how to complete this task.
