Query to Transpose Multiple Rows to Columns

[j1een]

Hi. I am a complete novice in using Access and am trying to figure
out how to transpose rows to columns in Access. The data I am trying
to transpose are the output of a query that performed calculations.
Here's the layout:

SubUnit Type T1 T2 T3
1A E 0.2 0.4 0.1
1A D 0.3 0.2 0.7
1B E 0.5 0.4 0.2
1C D 0.1 0.2 0.1

Here's how I need them:

Subunit Time E D
1A T1 0.2 0.3
1A T2 0.4 0.2
1A T3 0.1 0.7
1B T1 0.5 0.1
1B T2 0.4 0.2
1B T3 0.2 0.1


I realize that the existing layout may not be ideal, but try as I
might, I cannot figure a way to rearrange it given the calculations
that 1st need to be made to get it to this point. I've searched
online and think that a union and cross tab query might work but my
attempts thus far have been unsuccessful. As it often happens, I've
been asked to create this database for work without having any
official training in Access, so I'd greatly appreciate any help!

I'm not sure what happened to SubUnits 1C. I assume this should have been 1B.

Start by creating a normalizing query [quniToTranspose] with SQL like:
SELECT ToTranspose.SubUnit, ToTranspose.Type, ToTranspose.T1 AS TheValue,
"T1" AS TheTime
FROM ToTranspose
UNION ALL
SELECT ToTranspose.SubUnit, ToTranspose.Type, ToTranspose.T2, "T2"
FROM ToTranspose
UNION ALL
SELECT ToTranspose.SubUnit, ToTranspose.Type, ToTranspose.T3, "T3"
FROM ToTranspose;

Then create a crosstab with the SQL of:
TRANSFORM First(quniToTranspose.TheValue) AS FirstOfTheValue
SELECT quniToTranspose.SubUnit, quniToTranspose.TheTime
FROM quniToTranspose
GROUP BY quniToTranspose.SubUnit, quniToTranspose.TheTime
PIVOT quniToTranspose.Type;

Thank you so much! It worked like a charm!
