Image Data Type

In one of the table I have a column"XMLCompressed" with Image data type. I
don't know which type of file it is. I have tried with .xml, .svg, .jpeg etc
.
Is there any way to see what is stored inside that columnHi
Data is stored in binary format
best Regards,

Server doesn't care what
you put in there, and SQL server doesn't know what format you have in there.
I.e., there's no help
for SQL Server to be expected to understand the format of the data. Consider
having another column
in the table where you specify which format you have for each row (assuming
you have different
formats for different rows).

You can use image field in sql server as data type field , but I have
another approach to save your data and to be viewable by using ole control
from vb 6 (toolbox) or unbound-bound control in MSACCESS , and later you can
insert object and select as paintbrush object , so you can view this data by
screen or by report.
NB1 : Ole control dropped from VS 2005 (so be careful when you use this
approach)
NB2: Database will upsize quickly.

The person to ask this is the one who designed the table. Nobody else will k
now (for sure). We can
guess:
XML then zipped
XML then compressed to other standard formats
XML then compressed with some own compression algorithm
XML stored in a compressed format, defined by a standard body
I'd start with the last one. I did a Google on XML compressed and found hits
. I'd check first if
there is an accepted standard for storing XML data in a compressed format.

y
