Good evening, I have generated two queries to a PostgreSQL database, which are the following:
SELECT tarea, count(estado) AS "TotalCompletos" from tabla WHERE estado = 'Completo' GROUP BY tarea;
Query_1_result.png
SELECT tarea, count(estado) AS "TotalIncompletos" from tabla WHERE estado = 'Incompleto' GROUP BY tarea;
Query_2_result.png
My question is, how can I merge the above two queries into one query in order to produce a result similar to the following?
Expected_result.png
I have used UNION but I do not get the expected results. Attached is some sample code from the database I am using: Demo_DB
with q1 as (
SELECT tarea, count(estado) AS "TotalCompletos" from tabla WHERE estado = 'Completo' GROUP BY tarea
),
q2 as (
SELECT tarea, count(estado) AS "TotalIncompletos" from tabla WHERE estado = 'Incompleto' GROUP BY tarea
)
select tarea, coalesce("TotalCompletos", 0) as "TotalCompletos", coalesce("TotalIncompletos", 0) as "TotalIncompletos"
from q1 full join q2 using (tarea);

I have a thousand of records in one column and I want to cross join with date range let’s say between ‘2022-01-01 and ‘2022-02-15’. I don’t know how to start with sql server query, anyone can help?
Here’s my data (only one column)
City
Los Angeles
New York
Miami
Berlin
Dublin
Bologna
Desired result: (I shown 2 examples each only but the actual results should be 276 records)
Angeles/Dte-01Jan22
Los Angeles/Dte-02Jan22
New York/Dte-01Jan22
New York/Dte-02Jan22
Miami/Dte-01Jan22
Miami/Dte-02Jan22
Berlin/Dte-01Jan22
Berlin/Dte-02Jan22
Dublin/Dte-01Jan22
Dublin/Dte-02Jan22
Bologna/Dte-01Jan22
Bologna/Dte-02Jan22
You can do:
with
p (ds, de) as (
select convert(date, '20220101', 112), -- start date
convert(date, '20220215', 112) -- end date
),
r as (
select ds as d from p
union all
select dateadd(day, 1, r.d) from r join p on r.d < p.de
)
select concat(t.city, '/Dte', format(r.d, 'ddMMMyy'))
from r
cross join t
See running example at db<>fiddle.
This is how I understood the question, you should use this query:
SELECT * FROM dbo.Cities AS C
JOIN dbo.Dates AS D
WHERE D.Date BETWEEN '2022-01-01' AND '2022-01-30'
ORDER BY C.Name,D.Date
You can use CROSS APPLY on another queries :) JOINs have better performance on your data.
I need to join 2 tables using 2 columns as identifiers,
Reference and UAP
TABLE 1
Reference
UAP
Week 1
Week 2
Table 2
Reference
UAP
Stock
Here is the problem with data on both tables in UAP column
Table 1 Table 2
UAP1 M1
UAP2 M2
UAP3 M3
UAP4 M4
UAP5 M5
UAP6 M6
UAPP PROTOS
EXT EXTR
the UAPS are the same but name is just different
I have no control over the data i'm getting, it's a IBM DB2 remote server
I tried a local table to join but i want to avoid that 'cause of the performance impact (30+ seconds)
So far my query is this
SELECT
*
FROM OPENQUERY(MACPAC,
'SELECT
P.Referencia,
P.UAP,
P.W01,
P.W02,
S.Stock
FROM AUTO.D805DATPOR.Production AS P
INNER JOIN AUTO.D805DATPOR.Stock S
ON S.Reference = S.Reference
WHERE (P.Reference Not Like ''FS%'')
ORDER BY Reference')
well of course the ideal would be
SELECT
*
FROM OPENQUERY(MACPAC,
'SELECT
P.Referencia,
P.UAP,
P.W01,
P.W02,
S.Stock
FROM AUTO.D805DATPOR.Production AS P
INNER JOIN AUTO.D805DATPOR.Stock S
ON P.Reference = S.Reference AND P.UAP = S.UAP
WHERE (P.Reference Not Like ''FS%'')
ORDER BY Reference')
but it does not work cause different names... Is there a way to make this happen without a local join table that will slow my query by several seconds?
Here is the output of these queries individually
This is the production table
This is the stock table
the output should show me the Stock on the production table by Reference and UAP
EDIT
Sorry for confusion the remote server is IBM DB2. This was an error of my coworker that said it was coming from oracle--
Cheers for correct answer from #Sergey Menshov.
SELECT
Reference,
UAP,
W01,
W02
FROM OPENQUERY(MACPAC,
'SELECT
P.Reference,
P.UAP,
P.W01,
P.W02
FROM AUTO.D805DATPOR.Production AS P
LEFT JOIN AUTO.D805DATPOR.Stock S
ON P.Reference = S.Reference AND
S.UAP =
CASE P.UAP
WHEN ''UAP1'' THEN ''M1''
WHEN ''UAP2'' THEN ''M2''
WHEN ''UAP3'' THEN ''M3''
WHEN ''UAP4'' THEN ''M4''
WHEN ''UAP5'' THEN ''M5''
WHEN ''UAP6'' THEN ''M6''
WHEN ''UAPP'' THEN ''PROTOS''
WHEN ''EXT'' THEN ''EXTR''
END
WHERE (P.Reference Not Like ''FS%'')
ORDER BY Reference DESC')
another method which gives error in UAP1 not a column in table L that might work using dual table for DB2
SELECT
Reference,
UAP,
W01,
W02
FROM OPENQUERY(MACPAC,
'SELECT
P.Reference,
P.UAP,
P.W01,
P.W02
FROM AUTO.D805DATPOR.Production AS P
JOIN
(
SELECT ''UAP1'' AS UAP1, ''M1'' AS UAP2 FROM sysibm.sysdummy1
UNION ALL SELECT ''UAP2'',''M2'' FROM sysibm.sysdummy1
UNION ALL SELECT ''UAP3'',''M3'' FROM sysibm.sysdummy1
UNION ALL SELECT ''UAP4'',''M4'' FROM sysibm.sysdummy1
UNION ALL SELECT ''UAP5'',''M5'' FROM sysibm.sysdummy1
UNION ALL SELECT ''UAP6'',''M6'' FROM sysibm.sysdummy1
UNION ALL SELECT ''UAPP'',''PROTOS'' FROM sysibm.sysdummy1
UNION ALL SELECT ''EXT'',''EXTR'' FROM sysibm.sysdummy1
) L
ON P.UAP = L.UAP1
INNER JOIN AUTO.D805DATPOR.Stock S
ON P.Reference = S.Reference AND S.UAP = L.UAP2
WHERE (P.Reference Not Like ''FS%'')
ORDER BY Reference DESC')
Try to use a link-subquery:
FROM AUTO.D805DATPOR.Production AS P
JOIN
(
SELECT ''UAP1'' AS UAP1,''M1'' AS UAP2 FROM DUAL
UNION ALL SELECT ''UAP2'',''M2'' FROM DUAL
UNION ALL SELECT ''UAP3'',''M3'' FROM DUAL
UNION ALL SELECT ''UAP4'',''M4'' FROM DUAL
UNION ALL SELECT ''UAP5'',''M5'' FROM DUAL
UNION ALL SELECT ''UAP6'',''M6'' FROM DUAL
UNION ALL SELECT ''UAPP'',''PROTOS'' FROM DUAL
UNION ALL SELECT ''EXT'',''EXTR'' FROM DUAL
) L
ON P.UAP=L.UAP1 -- !!!
INNER JOIN AUTO.D805DATPOR.Stock S
ON P.Reference = S.Reference AND S.UAP=L.UAP2 -- !!!
Or you can create a link-table in the Oracle and then use it in your query.
I think it'll be better because you can use it in other queries and insert there a new combinations.
Pseudo code:
CREATE TABLE UAP_LINK(
UAP1 VARCHAR2(20) NOT NULL,
UAP2 VARCHAR2(20) NOT NULL,
PRIMARY KEY(UAP1),
UNIQUE(UAP2)
)
INSERT UAP_LINK VALUES
UAP1, M1
UAP2, M2
UAP3, M3
UAP4, M4
UAP5, M5
UAP6, M6
UAPP, PROTOS
EXT , EXTR
One more variant with CASE:
FROM AUTO.D805DATPOR.Production AS P
INNER JOIN AUTO.D805DATPOR.Stock S
ON P.Reference = S.Reference
AND S.UAP=
CASE P.UAP
WHEN ''UAP1'' THEN ''M1''
WHEN ''UAP2'' THEN ''M2''
WHEN ''UAP3'' THEN ''M3''
WHEN ''UAP4'' THEN ''M4''
WHEN ''UAP5'' THEN ''M5''
WHEN ''UAP6'' THEN ''M6''
WHEN ''UAPP'' THEN ''PROTOS''
WHEN ''EXT'' THEN ''EXTR''
END
SELECT h.*
FROM h
LEFT JOIN au ON au.ID = h.Key AND au.RaID = 40190 AND h.EntityType = 'Detail'
LEFT JOIN ip ON ip.ID = h.Key AND ip.RaID = 40190 AND h.EntityType = 'itempart'
WHERE
coalesce(au.id,ip.id) is not null
Anyone have a good idea how to optimize this? h is HUGE history log table.
what about using a union on your allowed types then you can use an inner join:
SELECT h.*
FROM h
INNER JOIN (
SELECT ID, 'Detail' AS EntityType FROM au WHERE (RaID = 40190)
UNION ALL
SELECT ID, 'itempart' AS EntityType FROM ip WHERE (RaID = 40190)
) AS filt
ON h.Key = filt.ID
AND h.EntityType = filt.EntityType
also make sure you have indexes on your filtered/joined columns. And as always when looking for performance issues check the query plan as n8wrl suggests above.
thanks in advance for you help. I'm still quite new to MS SQL db but I was wondering why my recursive query for MSSQL below does not return the value i'm expecting. I've done my research and at the bottom is the code I came up with. Lets say I have the following table...
CategoryID ParentID SomeName
1 0 hmm
2 0 err
3 0 woo
4 3 ppp
5 4 ttt
I'm expecting the query below to return 3 4 5. I basically wanted to get the list of category id's heirarchy below it self inclusive based on the category id I pass in the recursive query. Thanks for you assistance.
GO
WITH RecursiveQuery (CategoryID)
AS
(
-- Anchor member definition
SELECT a.CategoryID
FROM [SomeDB].[dbo].[SomeTable] AS a
WHERE a.ParentID = CategoryID
UNION ALL
-- Recursive member definition
SELECT b.CategoryID
FROM [SomeDB].[dbo].[SomeTable] AS b
INNER JOIN RecursiveQuery AS d
ON d.CategoryID = b.ParentID
)
-- Statement that executes the CTE
SELECT o.CategoryID
FROM [SomeDB].[dbo].[SomeTable] AS o
INNER JOIN RecursiveQuery AS d
ON d.CategoryID = 3
GO
If you want tree from specific root:
DECLARE #rootCatID int = 3
;WITH LessonsTree (CatID)
AS
(
SELECT a.CategoryID
FROM [EducationDatabase].[dbo].[LessonCategory] AS a
WHERE a.CategoryID = #rootCatID ---<<<
UNION ALL
SELECT b.CategoryID
FROM LessonsTree as t
INNER JOIN [EducationDatabase].[dbo].[LessonCategory] AS b
ON b.ParentID = t.CatID
)
SELECT o.*
FROM LessonsTree t
INNER JOIN [EducationDatabase].[dbo].[LessonCategory] AS o
ON o.CategoryID = t.CatID
As stated in the comments, the anchor isn't restricted. Easiest solution is to add the criterium in the anchor
with RecursiveQuery (theID)
AS
(
SELECT a.ParentID --root id=parentid to include it and to prevent an extra trip to LessonCategory afterwards
FROM [LessonCategory] AS a
WHERE a.ParentID = 3 --restriction here
UNION ALL
SELECT b.CategoryID
FROM [LessonCategory] AS b
INNER JOIN RecursiveQuery AS d
ON d.theID = b.ParentID
)
SELECT* from RecursiveQuery
Another option is to have the recursive query be general (no restricted anchor) and have it keep the rootid as well. Then the query on the cte can restrict on the rootid (the first option is probably better, this second one is mainly suitable if you are created some sort of root-view)
with RecursiveQuery
AS
(
SELECT a.ParentID theID, a.ParentID RootID
FROM [LessonCategory] AS a
UNION ALL
SELECT b.CategoryID, d.RootID
FROM [LessonCategory] AS b
INNER JOIN RecursiveQuery AS d
ON d.theID = b.ParentID
)
SELECT theID from RecursiveQuery where RootID = 3

The structure of an intersect query is as simple as:
select statement 1
intersect
select statement 2
intersect
select statement 3
...
This will return all columns that are in both select statements. The columns returned in the select statements must be of the same quantity and type (or at least be convertible to common type).
You can also do an intersect type of query just using inner joins to filter out records in the one query that are not in the other. So for a simple example let's say you have two tables of colors.
Select distinct ColorTable1.Color
from ColorTable1
join ColorTable2
on ColorTable1.Color = ColorTable2.Color
This will return all the distinct colors in ColorTable1 that are also in ColorTable2. Using joins to filter could help your query perform better, but it does take more thought.
