  I have pdf files stored in my sql db and would like to extract them to a folder. I have a script that will list them all but don't know how to actually write them to the folder. Can someone help me finish this up?

  declare @path varchar(100)= 'c:\images\'

  Select [CreatedDate], subject, @path+ltrim(subject)+'_'+filename as path

  from pdftable where subcategory='Finished Goods Certification' and (CreatedDate >= CONVERT(DATETIME, '2014-08-01 00:00:00', 102))

  order by CreatedDate

  thanks

  certainly possible, but you probably need a bit more information.

  this example here, you could adapt, and is assuming there is an identity/primary key to the table.

  If you can install CLR on a database, i personally use a version of Elliot Witlows Common Language Runtime example he published here:

  http://nclsqlclrfile.codeplex.com/

  --MSPSaveFileImage

  -- Parameters: @FilePath,@FileName,@FileBytes

  -- purpose: given an varbinary image column in a table, write that image to disk

  -- usage:

  --assumes table and the file from the example above for dbo.MFGetFileImage exists already.

  declare @myfile varbinary(max)

  SELECT @myfile = rawimage FROM myImages WHERE id = 1

  EXEC dbo.MSPSaveFileImage 'C:\Data','spinning.gif',@myfile

  Hi, Mark.

  Thanks for sharing your problem. When it comes to pdf processing, I have another question to ask you. I wonder whether text extraction from pdf files[/url] is much simpler than pdf to text conversion[/url] process. Thre's something wrong with my pdf viewer. I want to look for a method to help with the relevant process. Any suggestion will be appreciated. Thanks in advance.

  Best regards,

  Pan

  So I am new to SQL forums, so please bear with me. I have a similar issue. I have PDF's and JPG's stored within a table. Each record is associated with a session number as the number of PDF or JPG files per "session" can vary. I would like to export the files using the filename within the record for each file in a directory named using the session number. Any ideas/concerns?
