Subject equivalent of OnChange event (persistent fields) for TIB_Query fields
Author Jane Obenza
Hi all,

I need to set the value of Field2 to the result of a computation that uses
the value of Field1. I'm looking for something like the VCL's OnChange event
for persistent fields where Field2 displays the computed amount every time
Field1 is modified. How can I achieve this in the native IB query?

Thanks for any help.
