We had a few spreadsheets get imported multiple times into a database so we now have duplicate data (which of course had primary keys etc been assigned this would not have happed…)
However – the issue at hand is I need a way to return the data associated with the smallest (oldest) date for each PN
in the database. Below is a sample of the data and the structure. I tried to use Top 1
but I realized there was no rhyme or reason to what SSMS deemed as the 1st entry.
What would a query be for the syntax below to return the oldest date – expected returned results:
Number One 111111 2014-01-01
Number Two 2222 2014-02-22
Sample DDL ->
Declare @Test Table (pn varchar(200), ECN int, d1 date)
Insert Into @Test (pn, ECN, d1) Values
('Number One', '111111', '2014-01-01')
,('Number One', '111111', '2014-01-31')
,('Number One', '111111', '2014-02-14')
,('Number Two', '2222', '2014-02-22')
,('Number Two', '2222', '2014-02-25')
