Hi Everyone,
I am having one of those days when I just can't think creatively and would
like to ask for some help, please.
I realise what I am doing wrong... what I don't have is a sense of how to
do it correctly.
Please, let me give you the details in pseudo-code...
query "stuff" //gets lots of rows
loop stuff
employeeid = stuff.employeeid[i]
qoq = query of queries from "stuff" all rows that have stuff.employeeid
= employeeid
qoq also includes a sythetic column of max(date) as maxDate
so all rows of an employee have the same maxDate value
loop qoq
update a different table with a subset of qoq
do stuff based on employee with aggregated employee data
So assuming I have 3 rows of id 20,
I do something like;
update other table
set
columna = qoq.columnA[i],
-- " -- B = qoq.columnB[i],
....
newDate = maxdate
So the issue I have is that for each of the 3 instances of employeeid = 20
in STUFF, I do 3 updates
What I really want is just to do 1 set of updates per employeeid.
How do I exclude the 2nd and 3rd lot of updates? (in my example of
employeeid appearing 3 times in STUFF?
Obviously it gets worse - the more times a single employee appears in the
initial resultset!
As always thanks!
Gavin.
