This is what I use, except it's for text data types. I thought that varchar (if that's what your field is set as) is a max lenght of 4000. Anyway, here's my script to output text that is more than 4000 characters.


Declare @ptr varbinary(16),
@length int,
@Search varchar(200)

Set @Search = 'Title: 29aa58348'
--Set @Search = 'Title: 29aa58348'

Select @length = DataLength(FODocument)
From Admin..PrintJob
Where DocumentName = @Search

Select @ptr = TextPtr(FODocument)
From Admin..PrintJob
Where DocumentName = @Search

--Select @Search As [SearchParameter], @length As [LengthOfField], @ptr As [PointLocation]

If @ptr IS NOT NULL
ReadText PrintJob.FODocument @ptr 0 @length

instead of going for varbinary or something you can use varchar(max).

Just try out that.

Thanks,

You can use the substring function with text data, so you will not have to deal with text pointers. The only thing is that instead of specifying the offset as the start and length characters, it needs to be specified in bytes.
