Re: [MS_AccessPros] Re: Query the most recent date!

Rohn-

When you reply on the web, be sure to click Show Message History at the bottom of the reply window to make sure the thread stays intact.

The SQL I gave you does find the latest by employee ID:

SELECT License_Cert.[Emp#], License_Cert.Cert_Date, License_Cert.Cert_Title, License_Cert.Cert_NO, License_Cert.Issuing_Authority, Year([Cert_Date]) AS [YEAR], [First_Name] & ' ' & [Last_Name] AS Name, License_Cert.Cert_Expire_Date
FROM License_Cert INNER JOIN dbo_EMPLOYEE ON License_Cert.[EMP#] = dbo_EMPLOYEE.ID
WHERE (((License_Cert.[Emp#]) Like "*" & [Enter Employee Number:] & "*") AND ((License_Cert.Cert_Title) Like "*" & [Enter Cert Title:] & "*"))
AND License_Cert.Cert_Expire_Date = (SELECT MAX(Cert_Expire_Date) FROM License_Cert As L2 WHERE L2.[EMP#] = dbo_EMPLOYEE.ID);

If you want the latest by employee ID AND certificate, then do:

SELECT License_Cert.[Emp#], License_Cert.Cert_Date, License_Cert.Cert_Title, License_Cert.Cert_NO, License_Cert.Issuing_Authority, Year([Cert_Date]) AS [YEAR], [First_Name] & ' ' & [Last_Name] AS Name, License_Cert.Cert_Expire_Date
FROM License_Cert INNER JOIN dbo_EMPLOYEE ON License_Cert.[EMP#] = dbo_EMPLOYEE.ID
WHERE (((License_Cert.[Emp#]) Like "*" & [Enter Employee Number:] & "*") AND ((License_Cert.Cert_Title) Like "*" & [Enter Cert Title:] & "*"))
AND License_Cert.Cert_Expire_Date = (SELECT MAX(Cert_Expire_Date) FROM License_Cert As L2 WHERE L2.[EMP#] = dbo_EMPLOYEE.ID
AND L2.Cert_NO = License_Cert.Cert_NO);

If the certification numbers aren't unique, then you'll have to do it on title:

SELECT License_Cert.[Emp#], License_Cert.Cert_Date, License_Cert.Cert_Title, License_Cert.Cert_NO, License_Cert.Issuing_Authority, Year([Cert_Date]) AS [YEAR], [First_Name] & ' ' & [Last_Name] AS Name, License_Cert.Cert_Expire_Date
FROM License_Cert INNER JOIN dbo_EMPLOYEE ON License_Cert.[EMP#] = dbo_EMPLOYEE.ID
WHERE (((License_Cert.[Emp#]) Like "*" & [Enter Employee Number:] & "*") AND ((License_Cert.Cert_Title) Like "*" & [Enter Cert Title:] & "*"))
AND License_Cert.Cert_Expire_Date = (SELECT MAX(Cert_Expire_Date) FROM License_Cert As L2 WHERE L2.[EMP#] = dbo_EMPLOYEE.ID
AND L2.Cert_Title = License_Cert.Cert_Title);

Rohn,


You really need to provide more information. What you provided in this message lacks any Emp#. Please give all the information required such as all the significant fields and table names. Some sample records and desired results would be helpful.
