I want to process, in a SCAN loop, all records that satisfy a given condition. The condition is most easily expressed as a SELECT - SQL - but what is the best way to combine the two?
Pseudocode:
SCAN where KeyField in (SELECT KeyField from AnotherTable)
...
ENDSCAN
The processing itself is too complicated to place into a single INSERT - SQL command.
Basic criteria: 1) code should not be too messy, 2) it should be reasonably fast.
TIA, Hilmar.
