duplicate

Craig McLaughlin

I have something that I thought was simple but I was wrong.

I have a table which is a staff rota that covers more than one premises.

Day, Day Shift (which is a staff name), Back shift (which is also a staff
name), unit name

I need a query that searches to make sure that the same staff member has not
been selected to work on the same day in different premises.

So say staff 1 has been scheduled to do the day shift in Unit 1 on Monday,
and the back shift on Unit 3 on the Monday.

I need a query that finds such duplicates, but I just cant work it out.

Anyone ideas - because the data can be spread across different fields it is
difficult to work out.

Cheers

Craig

You can use a union query to get the data structured so this can be done more
simply.

SELECT Day, [Day Shift] as Staff, "Day" as Shift, [Unit Name] as Unit
FROM [Your Table]
UNION ALL
SELECT Day, [Back Shift] as Staff, "Back" as Shift, [Unit Name]
FROM [Your Table]

Now using that Saved query you can do the following
SELECT *
FROM qSavedUnionQuery
WHERE Day In(
SELECT Day
FROM qSavedUnionQuery as Temp
GROUP BY Day, Staff
HAVING Count(*)>1) And Temp.Staff=qSavedUnionQuery.Staff )

Thanks for the reply john.

I am not used to SQL and union queries and I copied your text into the sql
of the query.

I get an error on the temp.staff line which asks for the field. I am not
sure how to correct it.

this is the text I have entered

Sorry last post got cut short!!!

the SQL for the first query is

SELECT Day, [Staff Day] as Staff, "Day" as Shift, [Unit] as Unit2
FROM [Tbl_Template_Shifts]
UNION ALL SELECT Day, [Staff Back] as Staff, "Back" as Shift, [Unit]
FROM [Tbl_Template_Shifts];

My error. I had one too many parentheses in the second query. I removed the )
after Having Count(*)>1. The query now reads:

SELECT *
FROM qSavedUnionQuery
WHERE Day In(
SELECT Day
FROM qSavedUnionQuery as Temp
GROUP BY Day, Staff
HAVING Count(*)>1 And Temp.Staff=qSavedUnionQuery.Staff )

Hopefully this will work and give you the results you need.
