Michael,

Thank you for jump in. I have a table on the SQL Server called specimen with these fields: nidspecimen(surogate primary key), cspecimenid (my 'real' key), mnote (text filed causing trouble). In VFP, a remote view vspeciman is based on the specimen table.

When I do some thing in VFP, I can see exactly what SQL Command are sent to the server by using SQL Server Enterprise Manager, selecting menu Server-Current activities and right click on the connection to view detail.

In the VFP command window:
use vspecimen no data
insert into vspecimen(nidspecimen, cspecimenid, mnote);
values(14800, 'testmemo', 'this is memo contents')
=tableupdate()

Then the SQL Server goes crazy for a few minutes, and the record is inserted.
From the server current activities I found out this:

insert into specimen(nidspecimen, cspecimenid, mnote)
values(14800, 'testmemo ', '#odbc#chenna2')
select TEXTPTR(mnote) from specimen
where mnote like '#odbc#chenna2'

my SQL server user name is chennan and my workstation is also called chennan.

I also tried these:
1 - inserting a record without memo contents through vspecimen;
2 - using SPT to insert a record with memo contents;
3 - updating a record with memo contents throuth vspecimen;
The SQL Command they send to the server look normal.
