Hi,
I have a table that contains primary key. I get uniqueness error when I try to delete the record and create record with the same primary key. I was told that to have NOT DELETED() in primary key expression. However, i couldn't have the expression working in table designer.. can anybody help??
My code in expression column
Field      Type       Expression
myfield    Primary    myfield .AND. .NOT. DELETED()
VFP return expression is valid when I verify it. But I get another error message....

Thank you
