sql - Determining what this Delete Statement does -

-

not sql programmer. looks me looking exch_date today , deleting it. correct?

delete dbo.table  dateadd(dd, datediff(dd,0,exch_date),0) = dateadd(dd, datediff(dd,0,getdate()),0)

one way validate input select statement. identify rows affected.

select * db.table dateadd(dd, datediff(dd,0,exch_date), 0)     = dateadd(dd, datediff(dd,0,getdate()), 0)
