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 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.
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.
Hi, I have a table with a column having image data type in it.I need to move four records from this table to another table in development box.Can any one suggest me how can i do this? I don't think insert into select * will insert image data type.Is there any way around? thanks Mohan

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 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 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?
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?
I have an asp.net 2 app that retrieves images from a SQL Server 2005 Image field in our database. I have this working successfully apart from one problem. When I retrieve an animated gif, the animation is lost. Is there anyway around this?
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
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.

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.

Hi everyone, I have an odd problem. I have a generic upload/download ASP.net page that allows the upload and download of and type of file.

Hi, Does anyone know how to deal with image data type within stored procedure when using SQL2000? I have a table and there is an image data type column. In this table I need to make a copy of one row within a table through a SP /it means to retrieve the whole row within SP, change another columns data (but, that the image is not modified) / and save the modified row back to the same table. Problem is, that within SP is not alowed to use local varaibles of image data type. Does anyone know a solution for this? Please. Thank you.
I was working on figuring out where a certain application wasstoring the multiple selection choices I was doing through the app.I finally figured out that they were being store in an IMAGEdata type colum with the variable length of 26 bytes.This is the first time I ran into such way of storing multipleselections in a single Image data type.Is this a better alternative than to store into a One-to-Manytables? If so then I'll have to consider using the Image datatype approach next time I have to do something like storing1 to thousands of selections.Thank you
