SQL Date formulas to be able to use Query to mine data every 6 Months
Your assistance would be truly appreciated with this formula.
The query below is used to extract customer data for a specific time range.
I would like to set up a job that runs every six months using a query to generate a file with the current data.
In this query I am seeking to run I would like to use "b.docdate>='1/01/2016' and b.docdate<='6/30/2016' " but in a formula format that would run a report 6 Months back.
I would then fire the query up on 1/1 (for time period 7/1 to 12/31) and 7/1 (for 1/1 to 6/30) to generate the two yearly reports needed.
Your help with building a workable query is greatly appreciated.
Current Full Query:
Select
b.CustId,
a.Name,
b.RefNbr,
c.shipperid,
b.DocDate,
c.totinvc,
'' as SpaceHolder,
c.TotTax,
(c.totinvc-B.DocBal) As payments,
B.DocBal,
(c.totinvc-c.TotTax) AS subtotal,
c.TotMerch as RebateAmount,
(c.TotMerch*.05) as RebatePaid
from Customer a, ARDoc b, soshipheader c
where a.custid=b.custid and b.refnbr=c.invcnbr and
a.SlsperId like '%114'and
b.docdate>='1/01/2016' and b.docdate<='12/31/2016' -----> here is the line I would like to use a formula in place
order by a.CustId,b.RefNbr

WHERE condition for dates is below. Do not use a function on the column in the table to do the comparison, as that could very severely hurt performance.
...
WHERE ...
/* get dates in the full six-month period before the current month, no matter what day of month it currently is. */
/* for example, if run on *any* day in Jan, this would select dates from Jun 1 thru Dec 31.
b.docdate>=DATEADD(MONTH, DATEDIFF(MONTH, 0, GETDATE()) - 6, 0) and b.docdate<DATEADD(MONTH, DATEDIFF(MONTH, 0, GETDATE()), 0)

I was able to complete the query and set up an automated job that fires twice a year for the data I need.
Thanks all.
