how to pass outer query's table in inner query - sql

Question

This is my whole query
SELECT empmst.emp_id, empmst.emp_name,
(SELECT RTRIM
(XMLAGG (XMLELEMENT (e, d || ',')).EXTRACT ('//text()').EXTRACT
('//text()'),
','
)
FROM (SELECT TO_DATE ('01-04-2012', 'dd-MM-yyyy') - 1
+ ROWNUM AS d
FROM all_objects
WHERE TO_DATE ('01-04-2012', 'dd-MM-yyyy') - 1 + ROWNUM <=
TO_DATE ('30-04-2012', 'dd-MM-yyyy')
MINUS
SELECT tsd.ts_date
FROM ts_dtl tsd
WHERE empmst.emp_id = tsd.emp_id
AND tsd.ts_date BETWEEN TO_DATE ('01-04-2012',
'dd-MM-yyyy'
)
AND TO_DATE ('30-04-2012',
'dd-MM-yyyy'
))) AS day11
FROM emp_mst empmst
WHERE TSD.EMP_ID=EMPMST.EMP_ID
ORDER BY empmst.emp_id
I want to pass EMPMST.EMP_ID of the outer query to the inner query but inner query does'nt get EMPMST.EMP_ID in the where clause.
Please tell me how to pass outer query from table to inner query.
Inner query is as follows
(SELECT RTRIM
(XMLAGG (XMLELEMENT (e, d || ',')).EXTRACT ('//text()').EXTRACT
('//text()'),
','
)
FROM (SELECT TO_DATE ('01-04-2012', 'dd-MM-yyyy') - 1 + ROWNUM AS d
FROM all_objects
WHERE TO_DATE ('01-04-2012', 'dd-MM-yyyy') - 1 + ROWNUM <=
TO_DATE ('30-04-2012', 'dd-MM-yyyy')
MINUS
SELECT tsd.ts_date
FROM emp_mst empmst, ts_dtl tsd
WHERE empmst.emp_id = tsd.emp_id
AND ts_date BETWEEN TO_DATE ('01-04-2012', 'dd-MM-yyyy')
AND TO_DATE ('30-04-2012', 'dd-MM-yyyy')))
I want emp_name and emp_id and TS_date where TS_DATE which are not present in TS_DTL of april means the rest of the days of april which are not there in TS_DTL table

Answer 1

Please find the below which will achieve the same
SELECT EMPMST.EMP_ID,
EMPMST.EMP_NAME,
rtrim(xmlagg(xmlelement(e, b.d1 || ',')).extract('//text()')
.extract('//text()'),
',') as day11
from (SELECT TO_DATE('01-04-2012', 'dd-MM-yyyy') - 1 + rownum AS d1
FROM all_objects
WHERE TO_DATE('01-04-2012', 'dd-MM-yyyy') - 1 + rownum <=
TO_DATE('30-04-2012', 'dd-MM-yyyy')) b,
EMP_MST EMPMST
WHERE EMPMST.EMAIL_ID IS NOT NULL
AND EMPMST.DEPT IN ('Technical')
AND EMPMST.EMP_STATUS_LKP_ID = 201
AND b.d1 NOT IN
(SELECT TSD.TS_DATE as d2
FROM TS_DTL TSD
WHERE TSD.TS_DATE BETWEEN TO_DATE('01-04-2012', 'dd-MM-yyyy') AND
TO_DATE('30-04-2012', 'dd-MM-yyyy')
AND TSD.EMP_ID = EMPMST.EMP_ID)
ORDER BY EMPMST.EMP_ID
