How can I achieve this using SQL ?

[mrchonginhk]

I have a mdb table like this

Name Date Duration
========================
Paul 25-Jul-08 PM
John 26-Jul-08 Full Day

How can I turn it into this using SQL?

Name 25-Jul-08 26-Jul-08
=====================
Paul PM
John Full Day


Pls help. Thanks.

Hi,

This is how I'd do it in Excel. I assume Access is similar. HTH, Fazza

TRANSFORM MAX(Duration)
SELECT Name
FROM tblData
GROUP BY Name
PIVOT Date

It works !!! Thanks !!!!

What is the role of MAX here ??

 

[Fazza]

Glad it works.

Well, MAX is just a function to get the text into the cross tab.

I must stress I am not an Access user. This is just what I do in Excel for the same thing. The cross tab requires a function. Typically this might be a SUM. Or maybe AVERAGE or MAX or MIN or whatever. This works fine when you have numbers to add or average or whatever. As soon as the data is text, the SUM will 'bomb out'. So when I encountered text and wanted a cross tab result - and this was a couple of years ago, I think I've posted this in the Excel section some time ago - I tried the MAX function to see what would happen, and it worked. It was just an acceptable function in the cross tab that worked with text.

Regards, Fazza

That's fascinating (and useful!) Fazza

Thanks for the feedback, Richard.

I'll see if I can find an old Excel post where I might have done the same thing.

Just for interest, example of same approach previously http://www.mrexcel.com/forum/showthread.php?t=263782
I didn't explain the solution at the time - looks likes it would help if I did. I wouldn't have this time except that mrchonginhk asked...
