Hi Emanuele ... 8-)

I sovled the problem for MS SQL Server.
Infact reading again the BOL i discovered that using UPDATE to update an Image field, SQL server initialize the image pointer and preserve at least one page of data to store the effective datas.

So i added the lines reported below to my code where i force the use of WRITETEXT command to update image field.

The other solution to store on images field is the use of odbc API more elegant, more general (server independent) ..... but more complicated.

Have a nice week End!

TEXT TO o.UpdateCmd NOSHOW TEXTMERGE
DECLARE @ptrval binary(16)
UPDATE Images
SET Picture=NULL
WHERE Id_Images=?OLDVAL('id_images','images')

SELECT @ptrval = TEXTPTR(picture)
FROM images
WHERE id_images = ?OLDVAL('id_images','images')

WRITETEXT images.picture @ptrval ?images.picture

ENDTEXT
