Question

need ur help again

i have a sql table with column docid,proposedcompletiondate,docstatus

doc_id     ProposedCompdate    Docstatus
0001         2011-10-30           A
0002         2011-11-29           C
0003         2011-10-31           C
0004         2011-10-30           A
0005         2011-10-30           C
0006         2011-10-28           C
0007         2011-10-25           A
0008         2011-10-30           C

Now i want to write a query to fetch results with Docstatus 'A' whose date when subtracted by 9 days should be current date

for eg if todays Date is ’21-10-2011′

the resultset must be

doc_id     ProposedCompdate    Docstatus
0001         2011-10-30           A
0004         2011-10-30           A

Answer 1

This is assuming Microsoft SQL Server, but your where clause would be:

where Docstatus = 'A' AND DateDiff(day, GETDATE(), ProposedComplete) = 9

The DateDiff function takes a measurement parameter (day, year, etc), a beginning date and and end date and returns an integer. So the difference between today and ProposedComplete should be 9 days.
