Why Would Crystal Reports read more than it prints

Question

Hi everyone,
In my case My record selection is based on the following:
{FACILITY}=1
And {payment_code} In ["110","111","112","115","116","117"]
And {service_code} = "COPAY"
And {date_of_receipt} in [{?From Date} to {?To Date}]
And yet for any parameter selection set crystal reports would read - say - 1000 records but prints only 25 records, the question is if the records found according to the selected values from parameter and the record selection formula, is only 25 records, then why would it read 1000 records? what is the reason? and how to avoid it?
Thanks in advance!

Answer 1

It may also be what the numbers are telling you is the filter (WHERE) cannot be pushed down to the Server so CR has to filter it client side on the second pass.
Likely due to the data range, quite often the date format is not compliant to the Server so CR has to "interpret" the date format so it ends up filtering client side.
Try commenting out that part of the selection formula and see if you get the same number of records read. If you do then you could try using a SQL Express to convert the date fields or possibly using a Command and Command Parameter to set the date range may work for you. This way the DB is definitely getting the date formatted for it's server side use.
