How To Store And Retrieve DataTable As Blob

Apr 23, 2012

We are trying to store and retrieve datatable as blob (varbinary(max)). We convert the existing datatable into an xml file and store that xml file as a blob and while retrieving we get the blob as xml file and convert it back to datatble. It seems to be storing and retrieving the xml object but having issues while converting it back to the datatable ("End of stream - error").

Store BLOB With Program Code In SQL?

Feb 22, 2006

I am having a problem storing an image as a Blob in a SQL linked table. Our system uses an Access 2002 frontend and linked to a SQLServer2000 database. I have a form that I want to display a unique client jpeg photo for each client record. Our client HIPAA concerns means we have to store the image not the path in the database field. I am using an Image control on the form. Initially I have been able to load an image from a Windows Dialog into the control and save the path no problem.

My issues are surrounding how to actually save and load the jpeg as a BLOB in a VBA byte Array after the image has been loaded to the form from the dialog box.(Is there some sort of binary conversion needed or does the Append and GetChunk methods handle all this)?:

All the code examples I have been able to find on the subject have a line of code to set the Image control's data source to the open recordset with this statement ---> Set imgDBImage.DataSource = rs. Does this statement work with VBA because DataSource does not show up as a property of an Access 2002 Image Control. So how do I point the Image Control to the table field which contains the BLOB in VBA code?

Finally, how do you convert the string path of the image to binary for storage in a byte Array in VBA. I have the syntax for a VB 6.0 which is..... .Fields("ImageBLOB").AppendChunk bytBLOB. Is the .Fields portion of the code relevant in VBA to tell what table field to write to and does the AppendChunk method handle all the conversion?

Image Into Blob MySql VB2005

Feb 15, 2010

I have a project where the user wants an image stored in a Blob field of a MYSql database. I have been searching for info on the net but so far have not found a good solution for this.In this case the record will already exist in the database and I will need to insert the image into the existing record based on the recordid.Is there a simple way to do this perhaps with a stored procedure and an execute statement. I have very little experience with MySql and little with storing images in a database as well. Most often I will store the images as files and use a pointer in the db record but this user wants it in the db so here we are.

Zipping File Stored On SQL Server As Blob Image Field

I'm trying to zip a file that is stored on SQL Server as a blob image field and when downloading the zip file it says the file is corrupted.. or the file will open but contains some crazy characters.

Database Store Data To Dataset Temporarily?

Can you tell me what I am doing wrong with the program? I can't get queries to work either. It worked when I used the NOrthwind dataset this past weekend but it is not working when I use my own or empty dataset.

Store And Retrieve Data From An Access Database?

Dec 16, 2010

If you have to store and retrieve data from a database is a string not the most effcient way? What is best?

How does this work in a real world scenario.

For example: I have a customer ie first name and last name and the CustomerID is autoincremented when initially added to the database. Now, the user could lookup and find the customer by their ID but we all know that's not practical. They don't know 231223 is John Adams, they know John Adams or Adams John.

So how do you handle this? Access is the database I am using but I think this would apply to any database.

Ideally, I would love to click on the PrintDocument in a PrintPreviewControl and capture the coordinates of the PrintDocument.

Store/retrieve Millions Of Files When Their Meta-data Is In A SQL Database?

Aug 10, 2009

I have a process that's going to initially generate 3-4 million PDF files, and continue at the rate of 80K/day. They'll be pretty small (50K) each, but what I'm worried about is how to manage the total mass of files I'm generating for easy lookup. Some details:

I'll have some other steps to run once a file have been generated, and there will be a few servers participating, so I'll need to watch for files as they're generated.Once generated, the files will be available though a lookup process I've written. Essentially, I'll need to pull them based on an order number, which is unique per file.At any time, an existing order number may be resubmitted, and the generated file will need to overwrite the original copy.

Originally, I had planned to write these files all to a single directory on a NAS, but I realize this might not be a good idea, since there are millions of them and Windows might not handle a million-file-lookup very gracefully. I'm looking for some advice:

Is a single folder okay? The files will never be listed - they'll only be retrieved using a System.IO.File with a filename I've already determined.If I do a folder, can I watch for new files with a System.IO.DirectoryWatcher, even with that many files, or will it start to become sluggish with that many files?Should they be stored as BLOBs in a SQL Server database instead? Since I'll need to retrieve them by a reference value, maybe this makes more sense.
