Nesting Queries to get multiple column results - sql

Question

Have two queries , one collects moves in based on property and unit type the other would collect based on Move Outs for the same data. when ran separately they yield the correct information (move outs are 6 and move ins are 11) Have tried nesting in select and from statements but not getting what i need. When nested within the select am getting the correct move outs per unit type, but each line for move ins is total move ins. I recall that the nesting here would only return one value but know there is a way to return the value for each row. Any assistance is appreciated.
SELECT
p.scode as PropNumber,
p.saddr1 propname,
ut.scode as UnitType,
COUNT(t.hmyperson) as Moveouts,
(
SELECT COUNT(t.hmyperson) as MoveIns
FROM
tenant t
JOIN unit u ON t.hunit = u.hmy
JOIN property p ON p.hmy = u.hproperty
JOIN unittype ut ON ut.hmy = u.HUNITTYPE
WHERE
t.dtmovein >= getdate() - 14
AND p.scode IN ('gsaff')
) mi
FROM
Property p
JOIN unit u ON u.hproperty = p.hmy
JOIN tenant t ON t.hunit = u.hmy
JOIN unittype ut ON ut.hmy = u.HUNITTYPE
WHERE
p.scode IN ('gsaff')
AND t.DTMOVEOUT >= getdate()- 14
GROUP BY
ut.scode,
p.scode,
p.saddr1
With this data is coming out like :
PropNumber Propname UnitType MoveOuts MoveIns
1 x tc2 1 11
1 x tc3 2 11
1 x tc4 1 11
1 x tc5 1 11
1 x tc6 1 11 <pre>
Move in column should display as
2
5
1
0
3

You need to correlate the subquery according to the record being processed in the outer query. This also requires that you use different table aliases in the subquery than in the outer query.
It is hard to tell without seeing sample data, however I would expect that you need to correlate with all non-aggregated columns in the outer query.
Try changing :
(
SELECT COUNT(t.hmyperson) as MoveIns
FROM
tenant t
JOIN unit u ON t.hunit = u.hmy
JOIN property p ON p.hmy = u.hproperty
JOIN unittype ut ON ut.hmy = u.HUNITTYPE
WHERE
t.dtmovein >= getdate() - 14
AND p.scode IN ('gsaff')
) mi
To :
(
SELECT COUNT(t.hmyperson) as MoveIns
FROM
tenant t1
JOIN unit u1 ON t1.hunit = u1.hmy
JOIN property p1 ON p1.hmy = u1.hproperty
JOIN unittype ut1 ON ut1.hmy = u1.HUNITTYPE
WHERE
t1.dtmovein >= getdate() - 14
AND p1.scode IN ('gsaff')
AND p1.scode = p.scode
AND p1.saddr1 = p.saddr1
AND ut1.scode = ut.scode
) mi
