Hi,
I'm currently using mysql_store_result to retrieve all records of a
query. This poses a problem however if say a couple of thousand records
get returned, and the user gets no feedback during the progress. I now
want to change this to mysql_use_result. The only catch is that you
don't know how many records you're going to get and allocating memory
for them.
If I were to do a select count(*) from x where y prior to doing select *
from x where y to get a number of records, how would this impact
performance on the server itself? Would the first query be the one to do
the most processing, with the second one being faster, or would both
have to do the same amount of work?
Thanks,
Alex
