I think this was clear. What Elke has asked is how much data typically
is stored in your "content" field? Is it in the KB or GB range?

They need this information since - i think - it's much easier 
for the SAP DB people to introduce a "NOT SO LONG VARCHAR" type 
with a maximum of - say - 64 KB. Am i right?

But besides - what are the limitations of SQL Server for LONG 
VARCHAR? I think i have read about 8GB - and in this case i 
doubt SQL Server does accept a LIKE predicate on 8GB data, and 
- if it does - how is the performance? Does it scan the data on 
insert/update and creates some kind of hash table internally?
I think this is why they need BINARY and IMAGE subtypes.

Peter
