Hi Thomas,

I don't know what did he mean, this didn't come from me.

>The vfp implementation of update SQL works like the replace: if a field is updated and later in the same statement used as the source of the next assignment, the UPDATED value and not the OLDVALUE is used - which contradicts Celko in that matter, but is familiar to everyday vfp/xBase use.

I believe we don't have plans to change this behavior.

We don't have plans to extend this behavior to SQL.

Thanks,
Aleksey.
