Access Select Query to show the same field with a different criteria - sql

Question

I have a select query in Access 2010 which shows a 'Level Name' where the 'Period ID' is set to 1
How can i add another field to the query which also shows the Level Name where the Period ID is set to 2?
I would like them both to be next to each other in separate rows
For reference, my current query looks like:
SELECT
qryMaster.[First Name] & " " & qryMaster.[Last Name] AS ChildName,
qryMaster.LevelName
FROM
qryMaster
WHERE
(
(qryMaster.ClassID = [Forms]![frmViewRecords_subject]![cboClass])
AND
(qryMaster.SubjectID = [Forms]![frmViewRecords_subject]![cboSubject])
AND
(qryMaster.PeriodID = 1)
);
I have added a picture of how my current query looks like in a sub form. I would like a new Column next to september, but for a different period

Answer 1

A WHERE clause is always for all fields. So if you want two different WHERE clauses then you need two queries.
Otherwise try
AND (qryMaster.PeriodID In(1,2))

Answer 2

I know this thread was active five month ago, but I had the same problem, found this page with google. Asuming others will arrive here too, I'll post the two solutions that I found below.
SELECT t1.ChildName, t1.LevelName1, qryMaster.LevelName
FROM
((SELECT
qryMaster.[First Name] & " " & qryMaster.[Last Name] AS ChildName,
qryMaster.LevelName as LevelName1
FROM qryMaster
WHERE
(
(qryMaster.ClassID = [Forms]![frmViewRecords_subject]![cboClass])
AND
(qryMaster.SubjectID = [Forms]![frmViewRecords_subject]![cboSubject])
AND
(qryMaster.PeriodID = 1)
)) AS t1)
LEFT JOIN qryMaster
ON t1.ChildName = (qryMaster.[First Name] & " " & qryMaster.[Last Name])
WHERE (
(qryMaster.ClassID = [Forms]![frmViewRecords_subject]![cboClass])
AND
(qryMaster.SubjectID = [Forms]![frmViewRecords_subject]![cboSubject])
AND
(qryMaster.PeriodID = 2)
)
As I do not have your data I couldn't test the code for your data, therefore I am not sure whether the "ON" clause works like this. In my case I have some customer ID there.
And the second one:
SELECT t1.[First Name] & " " & t1.[Last Name] AS ChildName, t1.LevelName AS LevelName1, t2.levelName AS LevelName2
FROM qryMaster t1
INNER JOIN qryMaster t2 ON t1.Childname=(t2.[First Name] & " " & t2.[Last Name])
WHERE (
(t1.ClassID = [Forms]![frmViewRecords_subject]![cboClass]) AND
(t1.SubjectID = [Forms]![frmViewRecords_subject]![cboSubject]) AND
(t1.PeriodID = 1) AND
(t2.ClassID = [Forms]![frmViewRecords_subject]![cboClass]) AND
(t2.SubjectID = [Forms]![frmViewRecords_subject]![cboSubject]) AND
(t2.PeriodID = 2)
)
