convert data from multiple rows to multiple fields Access 2007 - ms-access-2007

Question

My table where I am storing my information is organized as follows:
ID JobID Project FirstName LastName
One job may have multiple projects and within the projects there may be up to 5 contacts. I would like to display the information in the following way:
ID JobID Project FirstName1 LastName1 FirstName2 LastName2.........FirstName5 LastName 5
Can a transform query be used for this or do you need to create another table and insert the information?
Thanks

Yes, what you describe is feasible. For test data in a table named [contactInfo]
ID JobID Project FirstName LastName
-- ----- ------- --------- --------
1 1 1 Homer Simpson
2 1 1 Marge Simpson
3 1 1 Lisa Simpson
4 1 2 Ned Flanders
start by creating a saved query in Access named [contactInfoRanked]
SELECT contactInfo.*, ranks.rowRank
FROM
contactInfo
INNER JOIN
(
SELECT t1.ID, Count(*) AS rowRank
FROM
contactInfo AS t1
INNER JOIN
contactInfo AS t2
ON t1.JobID = t2.JobID
AND t1.Project = t2.Project
AND t1.ID >= t2.ID
GROUP BY t1.ID
) AS ranks
ON contactInfo.ID = ranks.ID
which returns
ID JobID Project FirstName LastName rowRank
-- ----- ------- --------- -------- -------
1 1 1 Homer Simpson 1
2 1 1 Marge Simpson 2
3 1 1 Lisa Simpson 3
4 1 2 Ned Flanders 1
So now the query
SELECT
JobID,
Project,
"FirstName1" AS columnName,
FirstName AS columnValue
FROM contactInfoRanked
WHERE rowRank = 1
UNION ALL
SELECT
JobID,
Project,
"LastName1" AS columnName,
LastName AS columnValue
FROM contactInfoRanked
WHERE rowRank = 1
UNION ALL
SELECT
JobID,
Project,
"FirstName2" AS columnName,
FirstName AS columnValue
FROM contactInfoRanked
WHERE rowRank = 2
UNION ALL
SELECT
JobID,
Project,
"LastName2" AS columnName,
LastName AS columnValue
FROM contactInfoRanked
WHERE rowRank = 2
UNION ALL
SELECT
JobID,
Project,
"FirstName3" AS columnName,
FirstName AS columnValue
FROM contactInfoRanked
WHERE rowRank = 3
UNION ALL
SELECT
JobID,
Project,
"LastName3" AS columnName,
LastName AS columnValue
FROM contactInfoRanked
WHERE rowRank = 3
UNION ALL
SELECT
JobID,
Project,
"FirstName4" AS columnName,
FirstName AS columnValue
FROM contactInfoRanked
WHERE rowRank = 4
UNION ALL
SELECT
JobID,
Project,
"LastName4" AS columnName,
LastName AS columnValue
FROM contactInfoRanked
WHERE rowRank = 4
UNION ALL
SELECT
JobID,
Project,
"FirstName5" AS columnName,
FirstName AS columnValue
FROM contactInfoRanked
WHERE rowRank = 5
UNION ALL
SELECT
JobID,
Project,
"LastName5" AS columnName,
LastName AS columnValue
FROM contactInfoRanked
WHERE rowRank = 5
returns
JobID Project columnName columnValue
----- ------- ---------- -----------
1 1 FirstName1 Homer
1 2 FirstName1 Ned
1 1 LastName1 Simpson
1 2 LastName1 Flanders
1 1 FirstName2 Marge
1 1 LastName2 Simpson
1 1 FirstName3 Lisa
1 1 LastName3 Simpson
and we can just use that as the source for our crosstab query
TRANSFORM First(columnValue) AS colVal
SELECT JobID, Project
FROM
(
SELECT
JobID,
Project,
"FirstName1" AS columnName,
FirstName AS columnValue
FROM contactInfoRanked
WHERE rowRank = 1
UNION ALL
SELECT
JobID,
Project,
"LastName1" AS columnName,
LastName AS columnValue
FROM contactInfoRanked
WHERE rowRank = 1
UNION ALL
SELECT
JobID,
Project,
"FirstName2" AS columnName,
FirstName AS columnValue
FROM contactInfoRanked
WHERE rowRank = 2
UNION ALL
SELECT
JobID,
Project,
"LastName2" AS columnName,
LastName AS columnValue
FROM contactInfoRanked
WHERE rowRank = 2
UNION ALL
SELECT
JobID,
Project,
"FirstName3" AS columnName,
FirstName AS columnValue
FROM contactInfoRanked
WHERE rowRank = 3
UNION ALL
SELECT
JobID,
Project,
"LastName3" AS columnName,
LastName AS columnValue
FROM contactInfoRanked
WHERE rowRank = 3
UNION ALL
SELECT
JobID,
Project,
"FirstName4" AS columnName,
FirstName AS columnValue
FROM contactInfoRanked
WHERE rowRank = 4
UNION ALL
SELECT
JobID,
Project,
"LastName4" AS columnName,
LastName AS columnValue
FROM contactInfoRanked
WHERE rowRank = 4
UNION ALL
SELECT
JobID,
Project,
"FirstName5" AS columnName,
FirstName AS columnValue
FROM contactInfoRanked
WHERE rowRank = 5
UNION ALL
SELECT
JobID,
Project,
"LastName5" AS columnName,
LastName AS columnValue
FROM contactInfoRanked
WHERE rowRank = 5
)
GROUP BY JobID, Project
PIVOT columnName
IN
(
"FirstName1","LastName1",
"FirstName2","LastName2",
"FirstName3","LastName3",
"FirstName4","LastName4",
"FirstName5","LastName5"
)
which returns
JobID Project FirstName1 LastName1 FirstName2 LastName2 FirstName3 LastName3 FirstName4 LastName4 FirstName5 LastName5
