I have imported "blob" data from mysql to an ms-sql 2000 "Image" field, using ms- sql enterprise manager. However my c# image veiwer does not work on the imported blob data (it does work on data I add to ms-sql via my web application).
Is there any way I can check that the blob data creates a valid image? If anyone has any ideas of how I can debug the data coming out that would be great. Or perhaps someone can point me to somewhere I can get some help?
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.
Hi,This is driving me nuts, I have a table that stores notes regarding anoperation in an IMAGE data type field in MS SQL Server 2000.I can read and write no problem using Access using the StrConv function andI can Update the field correctly in T-SQL using:DECLARE @ptrval varbinary(16)SELECT @ptrval = TEXTPTR(BITS_data)FROM mytable_BINARY WHERE ID = 'RB215'WRITETEXT OPERATION_BINARY.BITS @ptrval 'My notes for this operation'However, I just can not seem to be able to convert back to text theinformation once it is stored using T-SQL.My selects keep returning bin data.How to do this! Thanks for your help.SD
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.
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 field in my personal table that has image data type as Pic,my SQL code is : SELECT Department.ID,Department.[Name],Department.CreatedDate,Department.[Pic] ,COUNT([Group].[Name]) FROM Department INNER JOIN [Group] ON Department.ID=[Group].DepartmentID Group by Department.ID,Department.[Name],Department.CreatedDate,Department.[Pic] This error occured : Msg 306, Level 16, State 2, Line 1 The text, ntext, and image data types cannot be compared or sorted, except when using IS NULL or LIKE operator. Please help me. Thanks.

I'm developing a website with SQL SERVER 2000 and IIS6 (beta). I'm using ASP.NET webforms for my application. I was wondering if anyone knows how to use the Image datatype for dynamically loading images/word docs/sound files
I have a large table at a client site, about 4000 rows so that is fine but the problem is one of the columns are of image type and this has a lot of data in the table size is about 2.8 gig. Whoever installed the server was up to no good - everything (logs, system and data files)is running on one disk which is mirrored (??? don't ask).
Indexes are on the right columns, and the server is a dual pentuim 3 700 with 2 gig of Ram so that is fine too.
The database is a CRM database (Maximizer) and when the application loads up it reads the entire table into its library (don't know why or how exactly yet) and as you can imagine this takes a long time about 4 minutes - which is too long.
My idea is to add two or more disks and get the logs on one of them then take the table with the image data and move it to one of the disks with the rest of the tables on the other disk - (The client can't afford or don't want to pay for a RAID system before you ask)
Can anyone shed some light on this whether it will do or do I rather need to go for a partitioned view over the disks.
What is the limits on TEXT IN ROW table option - will it be of any help?
Buying another server is unfortunatly not an option and archiving the older data also wont solve the problem as they do a lot of reports of the database.
Any suggestions or advice would very much be appreciated.
Been pondering the idea of putting 43 - 56K Pdf documents into a SQL DB but everything I've read only goes as far as to explain how the data is stored or manipulated.
I need to establish whether there are real performance issues or gains that will be experienced by doing this.
If indeed, performance would be a big issue, would storing the files in a Folder on another drive outside the Database be all that much faster (Let windows handle the fetch and carry instead of SQL Server).
The plan at the moment is to store all the image data in a separate data file or multiple data files. Using partitioned views is also a consideration.
Number of records per day (pdf's) would be somewhere around a 1000.

I am storing my upoaded images in sql server. However, if the user does not upload an image, a broken link is shown in the page. All that shows up in the DB field is <Binary>.
Can we set this field to a default value? Is it possible to view this binary data.
I would like a default blank gif to be returned if no image is uploaded.
I seem to be getting very annoying behaviour from SQL Server and was wondering what the correct method should be...I want to store some binary data in the database and I want to use a stored procedure. I also want to pass some XML to the stored procedure where this XML contains the binary data. I will then use OPENXML to grab the binary data and stick in the table. In order to ensure the safe transmission of the binary through XML I Base64 encode it. Ok so far. The problem is that although OPENXML is supposed to assume that anything marked as Image/Binary will be Base64 encoded it then proceeds to Base64 encode it again and put that result into the database! So what am I missing, am I supposed use a CDATA section or something rather than Base64 encode my XML?

I need to store images in MS SQL. I have the upload procedures and stuff but I'm missing the point about the image data type size.
It is supposed to be able to store up to 2Gb!!! but when I declare the data field image I can't specify the max size for the field and by default is 16 !!
16 bytes!! what can I do with that? How can I insert a file?
I have a string stored in a column of type image that I need to do string operations with in order to decode the containing infomation.
data [image] = 0x07FD0707FD0102F001000054004C005300410000000054004C00530041000000FF...
I can't cast or convert to nvarchar(max), varchar(max) as I always get an error. Explicit conversion from data type image to varchar(max) is not allowed.
I tried CONVERT(VARCHAR(MAX), CONVERT(VARBINARY(MAX), DATA))
Which doesn't throw an error but seems to interprete the hexadecimal code to ascii characters and therefore is useless (ýýð...)
I am working on application maintance. I got a Contains(myField, myString) that used to look into an image data type field (text) for the string, but right now it's not responding they way it's supposed to do.
Recently really big files have been introduced in the DB, could this related to the issue?
