I need to create a query that will extract all of the records

Resolved Question:

I need to create a query that will extract all of the records in a table with a unique value from a field with duplicate values.

Expert:  Richard replied 1 year ago.
Hi there and welcome

So to understand you want the query to make a unique id if it finds two of the same records in the tablet?
Customer: replied 1 year ago.


The "Incident number" field has many duplicate incident numbers, which represent different pieces of equipment responded to an emergency call. I want to create a table that just pulls each unique incident number with it's other corresponding information to create a new table.

Expert:  Richard replied 1 year ago.
Thanks Chuck

Than use this

Select * from tablet where incidentnumber in(select min(incidentnumber) from table)


Let me know if you have any problems please
Customer: replied 1 year ago.


Is this what you are talking about:


 


(select min (MODIFIED INCIDENT NO) from EMSOnlyCalYear2012)


 


I had to pull the "MODIFIED INCIDENT NO" down into a second query field as the * field doesn't allow criteria


 

Expert:  Richard replied 1 year ago.
yes that is it

Customer: replied 1 year ago.

I get a "syntax error" when I try to run it.


Syntax error in query expression '(((EMSOnlyCaiYear2012.[MODIFIED INCIDENT NO]}=(select min (MODIFIED NCIDENT NO) from EMSOnlyCaiYear2012)))'.

Expert:  Richard replied 1 year ago.
is this Microsoft Access? which version?
Customer: replied 1 year ago.

Yes, Access 2010

Expert:  Richard replied 1 year ago.
Can you upload the database here

www.wikisend.com

And give me the download link

there are soo many factors that can cause this, it is easier if I do the query in access for you

Customer: replied 1 year ago.
Expert:  Richard replied 1 year ago.
ok, I see the problem

You want to just select one incident number right? But which one is the correct one?
Customer: replied 1 year ago.


It doesn't matter as long as it just selects one incident number and excludes the duplicates

Expert:  Richard replied 1 year ago.
ok, I need to figure it out by going though the data

I am going offline now, can I resume this tomorrow?

Or would you like an other expert to take over?
Expert:  Richard replied 1 year ago.
ignore that, worked it out

uploading now
Customer: replied 1 year ago.


OK I'll await the download link.
