Select query with condition for the column from the second table - ms-access

Question

I have 2 tables (THour_IN and THour_OUT) that have identical schemas:
Columns for THour_IN: Name|date|HourIN
Colums for THour_OUT: Name|date|HourOUT
I make query:
SELECT THour_IN.Name, THour_IN.date, THour_IN.HourIN, THour_OUT.HourOUT FROM THour_IN LEFT JOIN THour_OUT ON (Hour_IN.Name = THour_OUT.Name) AND (Hour_IN.date = THour_OUT.date);
But this is not correct in my case, because I have multiple rows wtih the same date in the tables. The result is:
Name date HourIN HourOUT
AAA 24/11/2013 17:33:06 20:33:27
AAA 24/11/2013 17:33:06 16:36:06
AAA 24/11/2013 07:33:27 20:33:27
AAA 24/11/2013 07:33:27 16:36:06
BBB 18/11/2013 16:36:06
BBB 19/11/2013 07:33:30
BBB 21/11/2013 07:29:24 08:33:22
BBB 22/11/2013 07:33:30 16:34:53
It should be for date 24/11/2013 First HourIN(07:33:27) with Fisrt HourOUT (16:36:06), Second HourIN (17:33:06) with Second HourOUT (20:33:06) Any ideas?

Answer 1

Build segments, then intersect segments.
SELECT
P1.Name, P1.date, P1.HourIN, P1.HourOUT
FROM (
SELECT
I.Name, I.date, I.HourIN, O.HourOUT
FROM
THour_IN AS I
LEFT JOIN THour_OUT AS O
ON (I.Name = O.Name) AND (I.date = O.date)
AND I.HourIN < H.HourOUT
) AS P1
INNER JOIN (
SELECT
I.Name, I.date, I.HourIN, O.HourOUT
FROM
THour_IN AS I
LEFT JOIN THour_OUT AS O
ON (I.Name = O.Name) AND (I.date = O.date)
AND I.HourIN < H.HourOUT
) AS P2
ON P1.name = P2.name AND P1.date = P2.date
AND P1.HourIN <> P2.HourIN and P1.HourOUT <> P2.HourOUT
AND P1.HourOUT > P2.HourIN
AND (P1.HourIN = P2.HourIN AND P1.HourOUT < P2.HourOUT
OR P1.HourIN > P2.HourIN AND P1.HourOUT = P2.HourOUT)

Answer 2

You could use something like so:
SELECT
t.Name,
t.Date,
t.HourIN, (
SELECT Top 1 HourOut
FROM THourOUT o
WHERE o.Name=t.Name AND o.Date=t.date And o.HourOUT>t.HourIN
ORDER BY o.HourOUT,o.ID ) AS HrOut
FROM THourIN AS t
ORDER BY t.Date, t.HourIN;
Note that I have added an ID to the OUT table to ensure that top 1 does not return duplicates.
Here is an example of inserting missing values. It depends on a Numbers table containing integers from 0 or 1 to the highest number of missing values. A number table is useful in many ways.
INSERT INTO thourin
(name,
[date])
SELECT q.name,
q.DATE
FROM (SELECT Outs.name,
Outs.DATE,
Outs.countofout,
Ins.countofin
FROM (SELECT o.name,
o.DATE,
Count(o.name) AS CountOfOut
FROM thourout o
GROUP BY o.name,
o.DATE) AS Outs
LEFT JOIN (SELECT t.name,
t.DATE,
Count(t.name) AS CountOfIn
FROM thourin t
GROUP BY t.name,
t.DATE) AS Ins
ON ( Outs.name = Ins.name )
AND ( Outs.DATE = Ins.DATE )
WHERE (( ( Ins.countofin ) <> [countofout]
OR ( Ins.countofin ) IS NULL ))) AS q,
numbers AS n
WHERE (( ( n.counter ) > 0
AND ( n.counter ) <= [countofout] - [countofin] ))
