What about calculating the wages per rule per period and then aggregating them into counts? You could do it with either a view or derived table.

>>>Ok Folks,
>>>
>>>Here a problem I need help with, I am sure you will all rise to the occasion as you usually do.
>>>
>>>I am trying to create a query that summerizes employee tax data by taxing entity. Each taxing entity has its own tax_rule_id. I am getting the data for our pay histories table, which has a master table py_ehmast and a child table of py_ehtax with all the tax records. Each mast record is a payroll transaction/check.
>>>
>>>I need to not only summarize the data for each tax_rule_id but I need the summary for an entered date range, then month-to date, quarter-to-date and year-to-date. The user enteres the date range and I determine the dates from that. Not a problem.
>>>
>>>I also need the count of employees that had taxable wages for the period specified. So, I have all this working, here is a simplified version of the query...
>>>
>>>

>>>SELECT
>>>tax_rule_id
>>>,count(distinct case when chkdate between @pdbegin and @pdend then ee_id else null end) count_pd
>>>,count(distinct case when chkdate between @mbegin and @mend then ee_id else null end) count_mtd
>>>,count(distinct case when chkdate between @qbegin and @qend then ee_id else null end) count_qtd
>>>,count(distinct ee_id) count_ytd
>>>FROM py_ehtax t
>>>JOIN py_ehmast m ON t.ehmast_id = m.ehmast_id
>>>WHERE m.chkdate BETWEEN @ybegin AND @yend
>>>

>>>
>>>Ok, all that works great. The problem is. We allow the user to do adjustments. What that does is put records with negative values into the py_eh???? files. So, the sum will come out to the correct amount.
>>>
>>>So, it should be possible that for an ee_id for a specic tax_rule_id the sum for any of the for time ranges could be zero. In that case, I don't want the ee_id included in the count.
>>>
>>>If you understand this, do you have any ideas how I could do this.
>>>
>>>I thought to add to the WHERE something like
>>>
>>>

>>>ee_id IN (SELECT ee_id, tax_rule_id, sum(tax_cur)
>>>FROM py_ehtax t1
>>>join py_ehmast m1 on t1.ehmast_id = m1.ehmast_id
>>>WHERE ee_id = m.ee_id
>>>     AND tax_rule_id = t.tax_rule_id
>>>GROUP by ee_id, tax_rule_id
>>>HAVING sum(tax_cur) > 0)
>>>

>>>
>>>But, that would only apply to the YTD part...
>>>
>>>Thanks,
