Re: Performance and timestamp fileds

Probably but if possible i'd avoid it. The file has 2
millions records and is growing up fast. Our Iseries is a
270...
We run this query sometimes to chek any unusual combination
between documents dates and modification time stamp.
What is really strange is that if it doesn't use the
logical with DATEDOC the record count increase by 119.141
records, using the logical about 20.020 and very slow.
