Problem with driver ODBC / VB

Hello,
=20
These tests are done with the 2 versions of the driver 7.3
=20
Table User description : u_num int4 nextval( =85), u_comm varchar(512)
=20
In my table I have one row :=20
            u_num              1
            u_comm           =91hello world <CR><LF> all is fine.=92
=20
Imagine I want to delete this row
            Sql =3D =93select * from user where u_num=3D1=94
            Set rs =3D odbc_cnx.OpenResultset( sql, rdOpenKeyset,
rdConcurRowver )
            Rs.Edit
            Rs.delete
            Rs.close
The row is not deleted. Of course because in the log file, I find
            Sql =3D =93Delete from user where u_num=3D1 and u_comm=3D=91hel=
lo
world
all is fine.=92=94
=20
I have found how to do :
            Sql =3D =93select u_num from user where u_num=3D1=94
            Set rs =3D odbc_cnx.OpenResultset( sql, rdOpenKeyset,
rdConcurRowver )
            Rs.Edit
            Rs.delete
            Rs.close
And now it is ok since in the log file, I find
            Sql =3D =93Delete from user where u_num=3D1=94
=20
But I have the same problem with update :
            Sql =3D =93select u_num, u_comm from user where u_num=3D1=94
            Set rs =3D odbc_cnx.OpenResultset( sql, rdOpenKeyset,
rdConcurRowver )
            Rs.Edit
            Rs(=93u_comm=94).value =3D =93bonjour=94
            Rs.update
            Rs.close
In the log file, I find
            Sql =3D =93Update from user set u_comm=3D=92bonjour=92 where u_=
num=3D1
and u_comm=3D=91hello world
all is fine.=92=94
Is there anything to do to obtain from the driver something like :
            Sql =3D =93Update from user set u_comm=3D=92bonjour=92 where u_=
num=3D1=94
Since we don=92t need the second clause.

Thank you very much if you have a solution.
