First column in Hashed file should be a keyfield
Posted: Mon Jan 22, 2007 2:41 am
Hello,
I have read that the first column of a hashed file should be a keyfield. In the application I work on I have seen that this is not always the case although the job does what it has to do.
Can you tell me what the consequences are when the first column in a hashed file is not a keyfield and what if multiple key columns in a hashed file are not adjacent.
Kind regards,
Jan
