i will try and be as clear as possible on this one, as i have no idea what to do next and would love a kick in the right direction.
Im trying to compare the values within 2 tables. The tables look like this:
Table1:
Table2
INSERT INTO #table1 ([elementName], [elementValue])
VALUES
('t1','Project'),
('p1','test1'),
('n1','value1'),
('t2','Project'),
('p2','test2'),
('n2','value2'),
('t3','Project'),
('p3','test3'),
('n3','value3'),
('t4',''),
('p4',''),
('n4',''),
('t5',''),
('p5',''),
('n5','')
INSERT INTO #table2 ([elementName], [elementValue])
VALUES
('t1','Project'),
('p1',''),
('n1',''),
('t2','Project'),
('p2','test3'),
('n2','value123'),
('t3','Project'),
('p3',''),
('n3',''),
('t4','Package'),
('p4',''),
('n4',''),
('t5','Project'),
('p5','Testtest'),
('n5','valuevalue')
I used this code to fill the testtables. Normally this is an automated process, and the tables are filled from an XML string.
Furthermore, the numbers in the element name are considered "groups" meaning T1 P1 and N1 are together.
I would like to compare T1 and P1 etc from Table1 to any combination of T and P from table2
If they match, i would like to overwrite the value of Table 1 N1 with the value of the matched N on table 2. (in the example, table1 N3 would be replaced with table2 N2
Besides that i also want to keep every group in table 1 that is not in table 2
but also add every group that is in table 2 but not in table 1 on one of the blank spots.
Last but not least, if the T value is filled, but P value is empty, it does not have to overwrite/change anything in table1.
The expected result would be this:
Table1:
i made the changes bold.
I dont really have an idea on where to start on this. Ive tried functions as except and intersect, but did not get even close to what i would like to see.

I have an Oracle query to get only last 1 row data.
SELECT
R.FORM_NO,
R.PART_NO,
L.L_FORM_NO,
L.HDR_ID,
L.CP_ID_SLC_FORM_NO,
S.FORM_NO,
S.PART_NO,
S.CP_ID
FROM
WA_T_QC_REVISION R,
WA_T_QC_REVISION_LIST L,
WA_T_QC_CP_SELECTED S
WHERE
R.FORM_NO = L.HDR_ID AND
S.FORM_NO = L.CP_ID_SLC_FORM_NO AND
R.PART_NO = 'PA03670-B501'
ORDER BY R.FORM_NO DESC
When I try to adding the query to be like this:
SELECT * FROM(
SELECT
R.FORM_NO,
R.PART_NO,
L.L_FORM_NO,
L.HDR_ID,
L.CP_ID_SLC_FORM_NO,
S.FORM_NO,
S.PART_NO,
S.CP_ID
FROM
WA_T_QC_REVISION R,
WA_T_QC_REVISION_LIST L,
WA_T_QC_CP_SELECTED S
WHERE
R.FORM_NO = L.HDR_ID AND
S.FORM_NO = L.CP_ID_SLC_FORM_NO AND
R.PART_NO = 'PA03670-B501'
ORDER BY R.FORM_NO DESC)
WHERE ROWNUM <= 1
I got an error
ORA-00918: column ambiguously defined
What I want is to get only last 1 row data from tables.
The immediate fix here is to just alias the columns having the same name such that they no longer have the same name, e.g.
SELECT * FROM (
SELECT
R.FORM_NO AS FORM_NO_R,
R.PART_NO AS PART_NO_R,
L.L_FORM_NO,
L.HDR_ID,
L.CP_ID_SLC_FORM_NO,
S.FORM_NO AS FORM_NO_S,
S.PART_NO AS PART_ON_S,
S.CP_ID
FROM WA_T_QC_REVISION R
INNER JOIN WA_T_QC_REVISION_LIST L
ON R.FORM_NO = L.HDR_ID
INNER JOIN WA_T_QC_CP_SELECTED S
ON S.FORM_NO = L.CP_ID_SLC_FORM_NO
WHERE
R.PART_NO = 'PA03670-B501'
ORDER BY R.FORM_NO DESC
)
WHERE ROWNUM <= 1
Note also that I replaced your implicit joins with explicit inner joins. Using formal join syntax is the preferred way of writing queries (and has been for more than 25 years).
SELECT (
(SUM(t_price) - SUM(a_dvpay)) - (
SELECT SUM(inst_amount)
FROM installment
WHERE uid = user_info.uid
)
) AS remaining
FROM user_info
WHERE faculty_id = #faculty_id
GROUP BY uid;
This SQL query return the remaining result in multiple rows. I want to sum the values of remaining as Total remaining.
SQL Query Result
Remove the Group By clause.
SELECT ((sum(t_price) - sum(a_dvpay))-(select sum(inst_amount) from installment where uid=user_info.uid)) as remaining FROM user_info WHERE (faculty_id = #faculty_id)**strong text**
So it will be the sum of the amount(s) inside installment table, and I assume that not all members under a given faculty_id has a record there. In order to cater that, I used COALESCE to handle NULLS in the installment table:
SELECT ui.uid,
(SUM(ui.t_price) - SUM(ui.a_dvpay)) - SUM(COALESCE(i.inst_amount, 0)) `remaining`
FROM user_info ui
LEFT JOIN installment i ON i.uid = ui.uid
WHERE faculty_id = #faculty_id
GROUP BY ui.uid;
I found a solution that return what you needed:
SELECT SUM(remaining) FROM (
SELECT sum(t_price - a_dvpay) as remaining
FROM user_info
WHERE faculty_id = 1
UNION
SELECT -SUM(COALESCE(inst_amount,0))
FROM installment inst
WHERE uid IN (SELECT DISTINCT user_info.uid FROM user_info WHERE faculty_id = 1)
) x

I have a bit of a complex query .... I need to do an update statement on the summation of two union-ed SQL queries (problem is the data in the queries isn't numeric so i'm counting rows instead of summing values) but I then need to sum those rows.
UPDATE #LT_Actuals_TEMP
SET pCount = h.countPerfs
FROM (
select count(distinct c.perf_description) as countPerfs, b.program, b.Prog_id
from #LT_Actuals_TEMP TableP
where a.Performances = 'Y' and a.current_inactive = 0
group by b.Program, b.Prog_id
union
select distinct count(p.perf_code) as countPerfs, x.value, b.Prog_id
from T_PERF p
where x.content_type = 23
group by x.value, b.Prog_id
) h where h.Prog_id = #LT_Actuals_TEMP.program_id
the first query data comes back as such
countPerfs program Prog_id
7 Name 31
and second query comes back as
countPerfs program Prog_id
1 Name 31
what I need pCount to be set to at the end of the day is 8
Expected results
when I do select * from #LT_Actuals_TEMP
I see the value
8 for the Program Name, Id 31
You can solve it by adding another level in the from part where you sum up the data returned from the union.
Your query seems to be missing some source tables (as there are aliases used that don't point to anything) so I guess you're removed some parts, but in general it should look something like this:
UPDATE #LT_Actuals_TEMP
SET pCount = h.sum_of_countperfs
FROM (
select program, prog_id, sum(countPerfs) as sum_of_countperfs
from (
select count(distinct c.perf_description) as countPerfs, b.program, b.Prog_id
from #LT_Actuals_TEMP TableP
where a.Performances = 'Y' and a.current_inactive = 0
group by b.Program, b.Prog_id
union all
select distinct count(p.perf_code) as countPerfs, x.value, b.Prog_id
from T_PERF p
where x.content_type = 23
group by x.value, b.Prog_id
) as sub_q group by program, prog_id
) h where h.Prog_id = #LT_Actuals_TEMP.program_id
Also, you probably want to use union all so that duplicates are not removed.
I have one table vwuser. I want join this table with the table valued function fnuserrank(userID). So I need to cross apply with table valued function:
SELECT *
FROM vwuser AS a
CROSS APPLY fnuserrank(a.userid)
For each userID it generates multiple records. I only want the last record for each empid that does not have a Rank of Term(inated). How can I do this?
Data:
HistoryID empid Rank MonitorDate
1 A1 E1 2012-8-9
2 A1 E2 2012-9-12
3 A1 Term 2012-10-13
4 A2 E3 2011-10-09
5 A2 TERM 2012-11-9
From this 2nd record and 4th record must be selected.
In SQL Server 2005+ you can use this Common Table Expression (CTE) to determine the latest record by MonitorDate that doesn't have a Rank of 'Term':
WITH EmployeeData AS
(
SELECT *
, ROW_NUMBER() OVER (PARTITION BY empId, ORDER BY MonitorDate DESC) AS RowNumber
FROM vwuser AS a
CROSS APPLY fnuserrank(a.userid)
WHERE Rank != 'Term'
)
SELECT *
FROM EmployeeData AS ed
WHERE ed.RowNumber = 1;
Note: The statement before this CTE will need to end in a semi-colon. Because of this, I have seen many people write them like ;WITH EmployeeData AS...
You'll have to play with this. Having trouble mocking your schema on sqlfiddle.
Select bar.*
from
(
SELECT *
FROM vwuser AS a
CROSS APPLY fnuserrank(a.userid)
where rank != 'TERM'
) foo
left join
(
SELECT *
FROM vwuser AS b
CROSS APPLY fnuserrank(b.userid)
where rank != 'TERM'
) bar
on foo.empId = bar.empId
and foo.MonitorDate > bar.MonitorDate
where bar.empid is null
I always need to test out left outers on dates being higher. The way it works is you do a left outer. Every row EXCEPT one per user has row(s) with a higher monitor date. That one row is the one you want. I usually use an example from my code, but i'm on the wrong laptop. to get it working you can select foo., bar. and look at the results and spot the row you want and make the condition correct.
You could also do this, which is easier to remember
SELECT *
FROM vwuser AS a
CROSS APPLY fnuserrank(a.userid)
) foo
join
(
select empid, max(monitordate) maxdate
FROM vwuser AS b
CROSS APPLY fnuserrank(b.userid)
where rank != 'TERM'
) bar
on foo.empid = bar.empid
and foo.monitordate = bar.maxdate
I usually prefer to use set based logic over aggregate functions, but whatever works. You can tweak it also by caching the results of your TVF join into a table variable.
EDIT:
http://www.sqlfiddle.com/#!3/613e4/17 - I mocked up your TVF here. Apparently sqlfiddle didn't like "go".
select foo.*, bar.*
from
(
SELECT f.*
FROM vwuser AS a
join fnuserrank f
on a.empid = f.empid
where rank != 'TERM'
) foo
left join
(
SELECT f1.empid [barempid], f1.monitordate [barmonitordate]
FROM vwuser AS b
join fnuserrank f1
on b.empid = f1.empid
where rank != 'TERM'
) bar
on foo.empId = bar.barempid
and foo.MonitorDate > bar.barmonitordate
where bar.barempid is null
