Here is another thing.
I added a new compressible binary field to my table.
did the following
UPDATE ATT SET COMPRESS_FIELD = UNCOMPRESS_FIELD
to copy my uncompressed field data to the compressed field data.
Removed the old uncompressed field.
When I look at the file size of the ADM file, it is exactly the same even after packing!
Does this mean that the entire contents of my field were uncompressible?
What compression system does it use?
Do I have to compress the data myself first?
How is compression meant to work?
Is it a bug?
The online help doesn't mention this topic at all, just mentions the data type property.
