SELECT
a.price as price, b.id as id, b.tax as tax

Use left outer join you can get all the records from tableA.

I have four tables with data I want to put the respective total columns from each in a different column. However, I would like to match on dealerId. So if there is a dealerId in Table 1 and Table 3 that are the same, they should be a single row.
Table 1
dealerId | t1 Total Amount
---------+---------------
1 | 123
2 | 456
Table 2
dealerId | t2 Total Amount
---------+----------------
3 | 111
4 | 222
5 | 333
Table 3
dealerId | t3 Total Amount
---------+----------------
1 | 555
3 | 565
6 | 888
Table 4
dealerId | t4 Total Amount
---------+----------------
1 | 88
2 | 99
3 | 11
Desired Outcome
dealerId | t1Total Amount | t2Total Amount | t3 Total Amount | t4 Total Amount
---------+----------------+----------------+-----------------+-----------------
1 | 123 | null | 555 | 88
2 | 456 | null | null | 99
3 | null | 111 | 565 | 11
4 | null | 222 | null | null
5 | null | 333 | null | null
6 | null | null | 888 | null
I have basically created views (I don't know if this is the correct term for it) and tried to UNION ALL them, but this only gives me a single column with all the totals.
SELECT *
FROM
(
SELECT o.DealerId, Sum(oi.Amount) as T1_Total
FROM ....
) AS T1
UNION ALL
SELECT *
FROM
(
SELECT o.DealerId, Sum(oi.Amount) as T2_Total
FROM ....
) AS T2
UNION ALL
...
-- repeat for T3 and T4
You can also use the pivot operator:
select dealerId, T1, T2, T3, T4
from (
select dealerId, 'T1' as Src, "t1 Total Amount" as Amt from T1
union all
select dealerId, 'T2' , "t2 Total Amount" from T2
union all
select dealerId, 'T3' , "t3 Total Amount" from T3
union all
select dealerId, 'T4' , "t4 Total Amount" from T4
) vert
pivot (sum(Amt) for Src in (T1,T2,T3,T4)) horiz
Results:
dealerId T1 T2 T3 T4
----------- ----------- ----------- ----------- -----------
1 123 NULL 555 88
2 456 NULL NULL 99
3 NULL 111 565 11
4 NULL 222 NULL NULL
5 NULL 333 NULL NULL
6 NULL NULL 888 NULL
Try doing something like this:
with all_dealer_ids AS (
SELECT DISTINCT dealerId
FROM Table1
UNION
SELECT DISTINCT dealerId
FROM Table2
UNION
SELECT DISTINCT dealerId
FROM Table3
UNION
SELECT DISTINCT dealerId
FROM Table4
)
SELECT adi.dealerId, SUM(t1.TotalAmount) As T1TotalAmount, SUM(t2.TotalAmount) As
T2TotalAmount, SUM(t3.TotalAmount) AS T3TotalAmount, SUM(t4.TotalAmount) AS T4TotalAmount
FROM all_dealer_ids adi
LEFT JOIN Table1 t1
ON adi.dealerId = t1.dealerId
LEFT JOIN Table2 t2
ON adi.dealerId = t2.dealerId
LEFT JOIN Table3 t3
ON adi.dealerId = t3.dealerId
LEFT JOIN Table4 t4
ON adi.dealerId = t4.dealerId
GROUP BY adi.dealerId
ORDER BY adi.dealerId ASC
You'll want to use JOIN instead of UNION to accomplish what you're looking for. UNIONs are typically used to stack data, which is why you are seeing all your data in one column. You can try something like this to accomplish what you are looking for.
SELECT COALESCE(t1_totals.dealerID, t2_totals.dealerID, t3_totals.dealerID, t4_totals.dealerID) AS dealerId
, t1_totals.t1_total_amount
, t2_totals.t2_total_amount
, t3_totals.t3_total_amount
, t4_totals.t4_total_amount
FROM (
SELECT dealerID, sum(amount) AS t1_total_amount FROM t1 GROUP BY t1.dealerID
) AS t1_totals
FULL JOIN (
SELECT dealerID, sum(amount) AS t2_total_amount FROM t2 GROUP BY t2.dealerID
) AS t2_totals
ON t2_totals.dealerID = t1_totals.dealerID
FULL JOIN (
SELECT dealerID, sum(amount) AS t3_total_amount FROM t3 GROUP BY t3.dealerID
) AS t3_totals
ON t3_totals.dealerID = t1_totals.dealerID
FULL JOIN (
SELECT dealerID, sum(amount) AS t4_total_amount FROM t4 GROUP BY t4.dealerID
) AS t4_totals
ON t4_totals.dealerID = t1_totals.dealerID
ORDER BY dealerId
Table and field info as below.
Item ID (Column : Item ID / Desc)
=====================
Item ID Desc
0001 -------- A
0002 -------- B
0003 -------- null
Price Table (Column : Item ID / Price Level(lvl) / Price)
=========================================
Item ID Price Level Price
0001 ----------- 1 -------------3.99
0001 ----------- 2 -------------1.99
0002 ----------- 1 -------------2.99
0003 ----------- 1 -------------5.99
0003 ----------- 2 -------------3.99
(Default Price Level is "1")
so, Every item got the price level 1, some item got the price level 1 and 2
I use the full outer join 'Item' and 'Price' table.
select trs_itm.id, item.desc, price.lvl, price.price from trs_itm
full outer join item on trs_itm.id = item.id
full outer join price on price.id = item.id
group by trs_itm.id, item.desc, price.lvl, price.price
How to show the result of the query as below.
If some item has a price level '2', just show result price level 2.
but the item hasn't price level '2', just show default price level 1.
please, help me.
==============================================
ID Desc lvl price
0001 ------ A ---- 2 -------1.99
0002 ------ B ---- 1 -------2.99
0003 -----null --- 2 -------3.99
I don't know why you are doing a full outer join in this case.
Join the 2 tables and the query that returns the max price level for each item:
select i.*, p.pricelevel, p.price
from item i
inner join price p on p.itemid = i.itemid
inner join (
select itemid, max(pricelevel) pricelevel
from price
group by itemid
) g on g.itemid = p.itemid and g.pricelevel = p.pricelevel
order by i.itemid
Or with not exists:
select i.*, p.pricelevel, p.price
from item i inner join (
select p.* from price p
where not exists (
select 1 from price
where itemid = p.itemid and pricelevel > p.pricelevel
)
) p on p.itemid = i.itemid
order by i.itemid
See the demo.
Results:
> itemid | desc | pricelevel | price
> -----: | :--- | ---------: | ----:
> 1 | A | 2 | 1.99
> 2 | B | 1 | 2.99
> 3 | null | 2 | 3.99
For example i have a Table1:
ID Specified TIN Value DateCreated
----------------------------------
1 0 tin1 45 2014-12-30
2 1 tin2 34 2013-01-05
3 0 tin3 23 2015-02-20
4 3 tin4 47 2013-06-04
5 3 tin5 12 2012-04-02
And a Table2:
ID Table1ID RegistrationDate
----------------------------------
1 1 2015-10-12
2 2 2015-07-21
3 1 2015-11-26
4 1 2015-12-04
5 2 2015-09-18
I need select all columns from Table1 with first and last RegistrationDate column in Table2. The answer should be
ID Specified TIN Value DateCreated FirstRegDate LastRegDate
---------------------------------------------------------------
1 0 tin1 45 2014-12-30 2015-10-12 2015-12-04
2 1 tin2 34 2013-01-05 2015-07-21 2015-09-18
3 0 tin3 23 2015-02-20 NULL NULL
4 3 tin4 47 2013-06-04 NULL NULL
5 3 tin5 12 2012-04-02 NULL NULL
Hi one possible solution can be something similar to pseudo query below(if you can prepare the tables I will modify to reflect actual query)
SELECT table1.*, inlineTable2.firstRegDate, inlineTable2.lastRegDate
FROM Table1
LEFT JOIN
(
SELECT
Table1ID AS id,
MIN(registrationDate) as firstRegDate,
MAX(regsitrationDate) as lastRegDate
FROM table2
GROUP BY table1ID
) AS inlineTable2
ON table1.id = inlineTable2.id
You can group by all columns in table1, and look up the minumum and maximum registration date for the group:
select ID
, Specified
, ... other columns from table1 ...
, min(RegistrationDate)
, max(RegistrationDate)
from Table1 t1
left join
Table2 t2
on t1.ID = t2.Table1ID
group by
ID
, Specified
, ... other columns from table1 ...
Table_1 columns are:
======================
A B
======================
100 4
-----------
101 2
101 3
101 4
-----------
102 6
-----------
103 7
-----------
104 2
104 3
104 4
-----------
105 2
-----------
106 4
-----------
107 3
--------------------------------
Now I have input B parameter like '6' or '2,3,4'.
I want to get a result like this:
if input B parameter is '6', then output should be:
======================
A B
======================
102 6
If input B parameter is '2,3,4', then output should be:
======================
A B
======================
101 2
101 3
101 4
-----------
104 2
104 3
104 4
Just select the needed columns:
SELECT A, B
FROM Table_1
WHERE B IN (2,3,4)
EDIT:
If you need them only if all params are present
SELECT A, B
FROM Table_1
WHERE A IN (SELECT A FROM Table_1 WHERE B = 2) AND A IN (SELECT A FROM Table_1 WHERE B = 3) AND A IN (SELECT A FROM Table_1 WHERE B = 4)
You can try this one, for your specific requirement -
-- the last digit after = i.e. 3 should be replaced by number of inputs in check for our case it is 3 for (2,3,4)
SELECT A,B FROM Table_1 AS tbl1 WHERE B IN (2,3,4) AND (select COUNT(1) FROM Table_1 AS tbl2 WHERE B IN (2,3,4) AND tbl1.A = tbl2.A)
= 3
Please, have a look.
Thanks!
SELECT A
,B
FROM table_1
WHERE A IN (
SELECT A
FROM table_1
WHERE B = 2
)
AND A IN (
SELECT A
FROM table_1
WHERE B = 3
)
I want to join these two unrelated tables:
table 1
id name age
-- ---- ---
1 a 9
2 b 11
3 c 10
table 2
id school address
-- ------ -------
1 aa abc
1 aa efg
3 bb hij
Desired results:
id school address age name
-- ------ ------- --- ----
1 aa abc 9 a
1 aa efg 9 a
2 NULL NULL 11 b
3 bb hij 10 c
SELECT t1.id, t2.school, t2.address, t1.age, t1.name
FROM dbo.table1 AS t1
LEFT OUTER JOIN dbo.table2 AS t2
ON t1.id = t2.id
ORDER BY t1.id;
