Converting Bytes [] To An SQL CE 3 Image Type To Store
Dec 31, 2005
Hi,
I was wondering if anyone knows how to convert an array of bytes to an SQL CE 3 image type and vice versa.
I am using the SDF Signature control and I would like to store the signature as an Image. It needs to be an image so it can be synced with a desktop access 2003 database.
Hi when I store html file with image in image data type of database sqlserver, where will actual data store (content of html file, and file image which display on html file), in which folder Can I help 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
I have a field in my SQL Server 2000 with type "varbinary(8000)" which I merge onto my SQL CE 2.0 database. On my SQL CE 2.0, this field becomes "image".
Based on Microsoft's site: http://msdn2.microsoft.com/en-us/library/aa257477(SQL.80).aspx, "image" is used if the size is not over 510; however, when I populate this field in SQL CE, the maximum size that is stored is 510 bytes. I have verified my source data was complete (2622 butes) when again when I check the size of the field after an insert, it had only 510 bytes.
I am thinking that the way to do this would be to convert every 4 bytes into an int and create a temporaty table with an integer column which I populate with int and then run a select * on this temporary table.
Does anybody have any pointers on how I can start to do this?
Hi guys,I'm currently trying to insert image into my SQL db. I have tried a number of methods that were posted online, and so far with no luck.My current code reads: Dim conn As New Data.SqlClient.SqlConnection() conn.ConnectionString = ConfigurationManager.ConnectionStrings("MainDBConnection").ToString conn.Open() Dim cmd As New Data.SqlClient.SqlCommand("SP_SAVEImage", conn) cmd.CommandType = Data.CommandType.StoredProcedure Dim sImageName As New Data.SqlClient.SqlParameter("@sImageName", Data.SqlDbType.VarChar, 50) sImageName.Value = sImageName Dim sImageType As New Data.SqlClient.SqlParameter("@sImageType", Data.SqlDbType.VarChar, 50) sImageType.Value = fileType Dim sImageData As New Data.SqlClient.SqlParameter("@sImageData", Data.SqlDbType.Image, uploadedFile.Length) sImageData.Value = uploadedFile cmd.Parameters.Add(sImageName) cmd.Parameters.Add(sImageType) cmd.Parameters.Add(sImageData) Dim reader1 As Data.SqlClient.SqlDataReader reader1 = cmd.ExecuteReaderRunning through debug, everything runs up until the last line, where an error is caught saying : Failed to convert parameter value from a SqlParameter to a String I reckon it's to do with the input sImageData being input as a byte array - but I can't seem to find a way around it. Any help greatly appreciated!!
About 500 images, each about 20KB, are transferred at a time. Here is the problem - when this script is run manually, all the images are inserted completely. When the script is run as part of a job (that has several other steps), the job step completes successfully and all the images are inserted, but every single one is truncated to the first 1024 bytes of the image. What this ends up looking like on the website is a a narrow strip of image instead of a complete image. Here are some other observations:
- When I changed the "Eur_RMISWebInterface_GetProductImagesForWeb" SP to only return 1 product image instead of 500 it still failed - The owner of the job is the same Windows user as the user I have been running the script manually as - I have tried changing the datatype of image_data from image to varbinary(max) but it made no difference
Hi I have a asp:FileUpload conponent that I am trying to use to retrieve a picture file from the clients pc and store it in a SQL database. The table is called PropertyImage and it contains the following fields: imgID (type = int - autoincrement); imgData (type = Image); imgTitle (type = VarChar); imgType (type = VarChar); imgLength (type = BigInt); I have a button (Button1) which when clicked calls Button1_Click() --------------------------------------------------protected void Button1_Click(object sender, EventArgs e) {byte[] fileData = null; Boolean status = false;if (FileUpload1 != null) { // Make sure the file has data.if ((FileUpload1.PostedFile != null) && (FileUpload1.PostedFile.ContentLength > 0)) { // Get the filename.string fn = System.IO.Path.GetFileName(FileUpload1.PostedFile.FileName); try { // Access the file stream and begin the upload. Store the file in a memory byte array.Stream MyStream = FileUpload1.PostedFile.InputStream; long iLength = MyStream.Length;fileData = new byte[(int)MyStream.Length];MyStream.Read(fileData, 0, (int)MyStream.Length); MyStream.Close(); }catch (Exception ex) { } } }SqlConnection connection = new SqlConnection("Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\heidihomes.mdf;Integrated Security=True;User Instance=True"); try { connection.Open();SqlCommand sqlCmd = new SqlCommand("INSERT INTO PropertyImage (imgData, imgaTitle, imgType, imgLength) VALUES(@data,@title,@type,@length)"); SqlParameter param = new SqlParameter(); // String connectionString = new SqlConnection(sqlCmd, connection); param = new SqlParameter("@data", SqlDbType.Image); param.Value = fileData; sqlCmd.Parameters.Add(param);param = new SqlParameter("@title", SqlDbType.VarChar); param.Value = fileData; sqlCmd.Parameters.Add(param);param = new SqlParameter("@type", SqlDbType.VarChar); param.Value = fileData; sqlCmd.Parameters.Add(param);param = new SqlParameter("@length", SqlDbType.BigInt); param.Value = fileData; sqlCmd.Parameters.Add(param); sqlCmd.ExecuteNonQuery(); connection.Close();status = true; }catch (Exception ex){ }if (status) { UploadStatus.Text = "File Uploaded Successfully";Server.Transfer("Admin_PropertyView.aspx"); } else {UploadStatus.Text = "Uploaded Failed"; } } } -------------------------------------------------- But when I click on the button, nothing happens. Please could someone help me out here. I have tried this a few times and still haven't come right. Also, if there is something else wrong with the code, please let me know. Thanking you in advance.

hi to all !!!! i want to store the image file from user click in SQL Server , so how can i ?? How can i Store image (.jpg , .gif) in a database . pls send me Code or any thing which helps me ...
does anyone know a way, using native SQL, to store a result of a query in an image field of a certain table.
The case is we have a selfmade replication to communicate with several SQL servers in stores, this replication is over a telephone line. So we collect all the data using SQL statements and store them in a separate table as an image field. This is done know through a Delphi application that streams the resultset to a image field.
I am creating a document management systems using asp. I have beenresearching the different ways of handling the documents such as using thefile system and storing the path in the db, and actually storing thedocument in the db. I like the idea of storing it in the database muchbetter because I can allow users to manage documents themselves (I alreadyhave the code in place to do it if I decide), having a central system withthe ability to add my own document properties by adding fields to the table,security, and backups. I have found that most think it is better to storethe path due to performance issues and the rate the db can grow. I havelooked at our current system in access and we have a total of 4400 documents(of which probably 25% are in the database but don't actually exist anymorein the file system, one hangup about the file system) since 1988. Thiscomes to about 300 documents added each year. The other thing is the issuewith the size of the db. I don't see a whole lot of difference with thisissue because it is going to take up space in your file system too, althoughthe file system may be more efficient at storing them. I would say that 95%of our docs are under 1 mb in size and done in ms word.The last thing is using full-text search capabilities in SQL Server. I needto be able to search the contents of the field.Is there other issues around storing documents in the db to consider besidesthe above?
I have a table that contains the following two columns:BITS (image(16))BIT_LENGTH (int(4))When I look at the table, I see "OLE Object" in the BITS column. Whatsyntax should I use in a SELECT statement to convert the binary imageinfo contained in "BITS" into simple text that I can read? What roledoes the BIT_LENGTH field play?

I can populate a dataTable with type double (C#) of say '1055.01' however when I save these to the CE3.5 database using a float(CE3.5) I lose the decimal portion. The 'offending' code is:
We have some columns in a table where the date is stored as 19980101 (YYYYMMDD). The data type for this column is NUMBER(8) in Oracle.
I need to copy rows from Oracle to SQL Server using SSIS. I used the Data Conversion transformation editor to change it to DT_DATE, but the rows are not being inserted to the destination.
On Error, If I fail the component, then the error is :
There was an error with input column "ORDER_DATE_CONV" (1191) on input "OLE DB Destination Input" (29). The column status returned was: "Conversion failed because the data value overflowed the specified type.".

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.
