besides what Tom said.. another facet of the same issue.. when you do a
"NOT" query, it gathers all the potential results, from whatever other rules
are part of the query, then deletes the ones that are "NOT".. you can have a
200 meg, empty Answer table, if you started out with a 200 meg real table

Hi
I am using following query delete function to delete and to reduce file size
but the file size in window is the same.
ex before query delete
number of rec = 669035
file size 487186 kb
index size 1654 kb
after deleting 99% of the records the file size is
number of rec = 150
file size 487186 kb
index size 1654
Records were delete but the system file size does not change.
I have refreshed and reopen the folder to verify but still the same. Also
when I run a query the table it take as long, when the records size was
669035.
Any idea?
qbe = query
:workretail:ginv# | date |
delete |<~date1|
EndQuery
qbe.createauxtables(true)
qbe.executeqbe()
