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.
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
I have integer data stored in an image field. Every 2 bytes in the image field is a data point. Currently this data is extracted from within a VB6 application, converted to an ADO recordset and passed in to Crystal Reports. I'd like to find a way to unpack the data through a stored procedure and report from the store procedure instead (bypassing the VB6 application). Can some one point me in the right direction please? CREATE TABLE [dbo].[tblBottleGraphData] ([BottleID] [int] NOT NULL ,[GraphData] [image] NULL ,[TimeOffset] [int] NULL ,[ConcurrencyID] [int] NULL ) ON [SECONDARY] TEXTIMAGE_ON [SECONDARY]
Hi When images are uploaded and stored directly into a sql database as binary data (eg in the club starter kit) how can those images be accessed and displayed. When I open the images table in VWD and select display data, the cells holding the image data hold a <binary data> tag. What I want to be able to do is get at that data, or actually get at the image so that it is displayed. My reason is this, at the moment the only way to access the images in the sql database after they have been uploaded is to log into the website and view them as an administrator of the site. It would be much simpler if I could access the database directly and view the contents of the images table. Any ideas? Thanks
I am saving large text document in an image type of column in a SQL Server 2000 table. How will I set up searching of words/ phrases for data stored in this column?
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.
Hi, I have a website and i am uploading the gif image to the database. i have used varchar(500) as the datatype and i am saving the file in the webserver so the path to it c:intepub....a.gif
my upload table has the folliwing feilds UploadId Int Identity, Description, FileName, DiskPath varchar(500), weblocation varchar(500). I have a main sproc for the report where i am doing a inner join with other table to get the path of the gif..
So my question is how can i get a picture to show up on the report. . What kinda datatype the gif file should be stored in the database? If it is stored as a varchar how can i access it and what is best way to reference that particular.
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, Hi stored a xml file (gpx - track of a gps) in a database (Community Server 2008 - media part). Now I like to retrieve the xml and use it for google maps. Can I do a SELECT and retrieve the xml in the right format or something. Or should I download in some kind a way? Thanks! Roel
Hello group Is there a way to display an image stored in SQL without using a datagrid? I am using vb, the very few examples I do find open the image in a window by its self. Also is there a way find the height and width of an image stored in the database and the ability to change the image size? Example – when an image is uploaded to the database I would like a thumbnail to be created and also stored in the database. Any ideas please help. Michael
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 tried to insert a row using a clr stored procedure where a field was a varbinary(max) and the data was a jpg file. The data was truncated to 8000 bytes. A similar T-SQL sp did not truncate the data even though the parameters were identical. With the clr sp I tried varbinary, variant and image for the parameter type. The variant gave an exception. The others worked but the data was truncated.
I used sqlpipe.executeandsend. Someone asked elsewhere if the pipe had an 8000 byte limit but was told it had not.

I am trying to save an uploaded image and its associated info to sql server database using a stored procedure but keep getting trouble. When trying to save, the RowAffected always return -1. but when i debug it, I dont' see problem both from stored procedure server explore and codebehind. it looks to me every input param contains correct value(such as the uploaded image file name, contentType and etc). well, for the imgbin its input param value returns something like "byte[] imgbin={Length=516}". Below is my code, could anyone help to point out what did I do wrong? Thank you.

I work with Microsoft SQL Server 2005 on windows XP professional. I'd like to create stored procdure to add image to my database (jpg file). I managed to do it using VARCHAR variable in stored procedure and then using EXEC, but it don't work directly.
My Table definiton: CREATE TABLE [dbo].[Users]( [UserID] [int] IDENTITY(1,1) NOT NULL, [Login] [char](10), [Password] [char](20), [Avatar] [image] NULL, CONSTRAINT [PK_Users] PRIMARY KEY CLUSTERED ( [UserID] ASC )WITH (IGNORE_DUP_KEY = OFF) ON [PRIMARY] ) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
My working solution using stored procedure: ALTER PROCEDURE [dbo].[AddUser] @Login AS VARCHAR(255), @Password AS VARCHAR(255), @AvatarFileLocation AS VARCHAR(255), @UserId AS INT OUTPUT AS BEGIN SET @Query = 'INSERT INTO USERS ' + CHAR(13) + 'SELECT '''+ @Login + ''' AS Login, ' + CHAR(13) + '''' + @Password + ''' AS Password,' + CHAR(13) + '(SELECT * FROM OPENROWSET(BULK ''' + @AvatarFileLocation + ''', SINGLE_BLOB) AS OBRAZEK)' EXECUTE (@Query) SET @UserID = @@IDENTITY END
I'd like to use statement in the stored procdure: ALTER PROCEDURE [dbo].[AddUser] @Login AS VARCHAR(255), @Password AS VARCHAR(255), @AvatarFileLocation AS VARCHAR(255), @UserId AS INT OUTPUT AS BEGIN DECLARE @Query AS VARCHAR(MAX)
SET @AvatarFileLocation = 'C:hitman1.jpg' INSERT INTO USERS SELECT @Login AS Login, @Password AS Password, (SELECT * FROM OPENROWSET(BULK @AvatarFileLocation, SINGLE_BLOB) AS OBRAZEK)
SET @UserID = @@IDENTITY
END
It generates error: Incorrect syntax near '@AvatarFileLocation'.
My question is: Why it does not work and how to write the stored procedure code to run this code without errors.
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 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.

Please help me. Thanks.

I have a ot of images in my hard disk and I want to put these ina table in a column declared as an image datatype. How do I do it?

I know about the textptr function but the booksonline doesn't show mw how to set my textptr to a specific location on my hard rive. Any help is appreciated. I need this because the customers do send the images of their proucts which should go into the database.
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.
pls. Help! I am not getting that how to use the image datatype in sql server 2000 when i am inserting text to it and on retrieving it is showing hexadecimal string ... I want to know all of your views on the usage of image datatype.. Thanks...
