I have got a requirement to display a query which shows matching and non matching rows against the master lookup table
The #PostCodes table contains the postcodes for master table which the second query would be matched against
DECLARE #PostCodes TABLE
(
RowID int not null primary key identity(1,1),
Postcodes varchar(100)
)
SELECT
C.CampaignId, C.Name, C.Description,C.EndedOn, C.Active, C.Manager,
P.PostcodeArea, P.PostcodeDistrict
FROM
Campaign C, CampaignPostcode P, #PostCodes pc
WHERE
P.CampaignId = C.CampaignId AND
P.PostcodeDistrict = pc.Postcodes AND
C.EndedOn IS NULL
The second query returns me only the matching records against postcodes and I have tried everything to include unmatched records but no luck.
Any help?
EDIT (Tables)
PostCodes (table1) Campaign (table2)
Id Postcodes CampaignId Name Desc
1 AA 1 camp1 Desc1
2 AB 2 camp2 Desc2
3 AC 3 camp3 Desc3
4 AD 4 camp4 Desc4
CampaignPostcode (table3)

Id CampaignName Desc PostcodeIn PostcodeOut
1 Camp1 Desc1 AA NULL
2 Camp2 Desc2 AB NULL
3 Camp2 Desc2 AB NULL
4 Camp3 Desc3 AC NULL
5 Camp4 Desc4 NULL AD
What about this:
SELECT
C.CampaignId, C.Name, C.Description,C.EndedOn, C.Active, C.Manager,
P.PostcodeArea, P.PostcodeDistrict
FROM
Campaign C
INNER JOIN
CampaignPostcode P ON P.CampaignId = C.CampaignId
LEFT OUTER JOIN
#PostCodes pc ON P.PostcodeDistrict = pc.Postcodes
WHERE
C.EndedOn IS NULL
Try this instead:
SELECT
p.*
FROM #PostCodes AS PC
LEFT JOIN
(
SELECT *
FROM Campaign C
INNER JOIN CampaignPostcode P ON P.CampaignId = C.CampaignId
) AS p ON P.PostcodeDistrict = pc.Postcodes
WHERE P.EndedOn IS NULL

I need to write query that will get all reserved coils (reserved_coils) that has status 2 and for each coil I need to join tables for materials and colors
material
ID
NAME
1
color
ID
NAME
I wrote query but it doesn't show coils in transport that are reserved, here is what I tried
SELECT a.QUANTITY, a.START, a.END, b.name, m.name
FROM reserved_coils a
LEFT JOIN coils b ON a.number = b.serial
LEFT JOIN coils_in_transport c ON a.number = c.serial
LEFT JOIN material m ON b.material = m.id
LEFT JOIN material b ON b.material = b.id
where b.status = 2 and c.status = 2
To get all coils and colis_in_transport you need to use UNION for SELECT statements for both tables, each filtered by status value, which should be equal to 2. Then you need to do a JOIN between reserved_coils and the result of UNION to filter out reserved_coils rows.
Your query would be like this
SELECT
r.quantity,
r.start,
r.[end],
c.serial,
material.name AS material,
color.name AS color
FROM reserved_coils r
JOIN (
SELECT * FROM coils WHERE status = 2
UNION
SELECT * FROM coils_in_transport WHERE status = 2
) c ON r.number = c.serial
LEFT JOIN material ON material.id = c.material
LEFT JOIN color ON color.id = c.color
Demo
If you want left join twice on same table, this might help
SELECT a.QUANTITY, a.START, a.[END], isnull(b.serial,c.serial) serial,isnull(c1.name,c2.name) color, isnull(m.name,n.name) material
FROM reserved_coils a
LEFT JOIN coils b ON a.number = b.serial
LEFT JOIN coils_in_transport c ON a.number = c.serial
LEFT JOIN material m ON b.material = m.id
LEFT JOIN material n ON c.material = n.id
LEFT JOIN color c1 on b.color=c1.id
LEFT JOIN color c2 on c.color=c2.id
where isnull(b.status,c.status) = 2

I am looking for a SQL query to update all the columns in table A which has a NULL value to NOT NULL values from table C using reference as table B. All the columns in table A should be updated using a single query or dynamic query. Values should be updated based on column name and values should not be hard coded.

In the output, all the NULL column values in table A are updated with NOT NULL values from table C. Please provide a single query to update all the NULL columns in a single query itself.
I am trying below query but unable to update the table with max Function. Is there any alternative for it.
Select * into #temp FROM

INNER JOIN tableB B ON A.ID = B.ID
INNER JOIN tableC C ON B.RollNo = C.RollNo
)X where RNK = 1
UPDATE A SET Name =
CASE
WHEN MAX(A.Name) IS NULL THEN MAX(C.Name)
ELSE Max(A.Name) END
, Zip =

INNER JOIN tablec C ON B.RollNo = C.RollNo
Getting an error:
An aggregate may not appear in the set list of an UPDATE statement.
I need all the values in output table along with null values updated with not null values.
Try this below script-

I have a query and I want to look up the values from other table as a reference but not mess up my current query results. I think I have to use a Outer Left Join, but not sure how to incorporate that with my current query.
My current query looks similar to this:
SELECT a.primary_key,
a.phase,
b.project_number,
c.LENGTH,
d.color
FROM TableA a,
TableB b,
TableC c,
TableD d
WHERE c.primary_key = a.PROJECT_ID
AND b.primary_key = a.PROJECT_ID
AND b.primary_key = d.project_ID
AND (c.date IS NULL OR c.number IS NULL)
AND d.color IN ('black','red','blue')
ORDER BY 1
Now, that gives me a table of 50 results. 'TableContacts' has the look up value to my b.project_number. So say my table of 50 results, only 10 of them have b.project_number, I need the lookup values from 'TableContacts' to also show in my results, but I don't want that to affect my results and cut it down to 10, I still need my original 50 results, just with that additional information. Help?
Just add the CONTACTS table to your joins:
SELECT a.primary_key,
a.phase,
b.project_number,
c.LENGTH,
d.color,
ct.lookup_value --<< this is from the CONTACTS table
FROM TableA a
JOIN TableB b ON b.primary_key = a.PROJECT_ID
JOIN TableC c ON c.primary_key = a.PROJECT_ID
JOIN TableD d ON b.primary_key = d.project_ID
LEFT JOIN contacts ct ON ct.some_column = b.project_Number --<< this is the outer join to the CONTACTS table
WHERE (c.date IS NULL OR c.number IS NULL)
AND d.color IN ('black','red','blue')
ORDER BY 1
As you obfuscated your table and column names it's hard to guess how exactly the join condition on the CONTACTS table should look like.
You could use this approach:
Create a table with the results of your current query:
create table t1 as
SELECT a.primary_key,
a.phase,
b.project_number,
c.LENGTH_col,
d.color
FROM a,b,c,d
WHERE c.primary_key = a.PROJECT_ID
AND b.primary_key = a.PROJECT_ID
AND b.primary_key = d.project_ID
AND (c.date_col IS NULL OR c.number_col IS NULL)
AND d.color IN ('black','red','blue')
ORDER BY 1;
Use a union to get the desired results:
select t1.primary_key, t1.phase, t1.project_number, t1.length_col, t1.color, TableContacts.lookup_column
from t1, TableContacts
where t1.project_number = TableContacts.project_number
UNION
select t1.primary_key, t1.phase, t1.project_number, t1.length_col, t1.color, null
from t1 where t1.project_number is null;
Illustration by creating dummy data:
select * from a;
PRIMARY_KEY | PROJECT_ID | PHASE
1 100 Phase-1
2 200 Phase-2
3 300 Phase-3
4 400 Phase-4
5 500 Phase-5
select * from b;
PRIMARY_KEY | PROJECT_NUMBER
100 null
200 2000
300 3000
400 null
500 5000
select * from c;
PRIMARY_KEY | NUMBER_COL | LENGTH_COL | DATE_COL
100 null 99 null
200 null 99 null
300 null 99 null
400 null 99 null
500 null 99 null
select * from d;
PROJECT_ID | COLOR
100 black
200 red
300 blue
400 black
500 yellow
select * from TableContacts;
PROJECT_NUMBER | LOOKUP_COLUMN
1000 l-1000
2000 l-2000
3000 l-3000
4000 l-4000
5000 l-5000
Existing query in question returns this:
SELECT a.primary_key,
a.phase,
b.project_number,
c.LENGTH_col,
d.color
FROM a,b,c,d
WHERE c.primary_key = a.PROJECT_ID
AND b.primary_key = a.PROJECT_ID
AND b.primary_key = d.project_ID
AND (c.date_col IS NULL OR c.number_col IS NULL)
AND d.color IN ('black','red','blue')
ORDER BY 1;
PRIMARY_KEY | PHASE | PROJECT_NUMBER | LENGTH_COL | COLOR
1 Phase-1 null 99 black
2 Phase-2 2000 99 red
3 Phase-3 3000 99 blue
4 Phase-4 null 99 black
The goal is to populate the lookup_column where project_number is not null. Running the union query provided at start of answer:
select t1.primary_key, t1.phase, t1.project_number, t1.length_col, t1.color, TableContacts.lookup_column
from t1, TableContacts
where t1.project_number = TableContacts.project_number
UNION
select t1.primary_key, t1.phase, t1.project_number, t1.length_col, t1.color, null
from t1 where t1.project_number is null;
PRIMARY_KEY | PHASE | PROJECT_NUMBER | LENGTH_COL | COLOR | LOOKUP_COLUMN
1 Phase-1 null 99 black null
2 Phase-2 2000 99 red l-2000
3 Phase-3 3000 99 blue l-3000
4 Phase-4 null 99 black null
I have 4 tables
Table1 : Employeetab
Employeeid EmployeeName
1 xyz
2 abc
3 mno
4 pqr
Table2 : PurchaseRequesttab
PRID Employeeid PRNR
1 1 pr1
Table3 : Statustab
StatusID Statusmsg
1 approve by manager
2 approve by CC manager
3 approve by designer
4 approve by BU head
Table4 : ApprovalStatustab
PRID StatusID Employeeid ApprovalDate
1 1 3 jan 1 2015
1 2 3 jan 3 2015
1 4 4 Jan 5 2015
Result should be
PRNR EmployeeName Statusmsg
pr1 mno approve by CC manager
Below is my query, which gives duplicate
Select
distinct P.PRNR, EmployeeName, Statusmsg
from Employeetab as E
inner join PurchaseRequesttab AS P ON E. Employeeid = p.Employeeid
inner join ApprovalStatustab as A ON P. PRID = A. PRID
inner join Statustab as S on A. StatusID = S. StatusID
How to get unique records in the result set, edited the result :)
Some thing your data is mismatch with your entry and your table structure.
1. ApprovalStatustab A and PurchaseRequesttab as P - P.PRID = A.PRID mismatch entry as above.
Here is your sample query below, I comment and add some entry for better understand what you doing wrong.
declare #Employeetab table(Employeeid int, EmployeeName varchar(50))
declare #PurchaseRequesttab table(PRID int,Employeeid int, PRNR varchar(50) )
declare #Statustab table(StatusID int, Statusmsg varchar(50) )
declare #ApprovalStatustab table(PRID int, StatusID int, Employeeid int, ApprovalDate varchar(50) )
insert into #Employeetab values (1,'xyz'),(2,'abc'),(3,'mno'),(4,'pqr')
insert into #PurchaseRequesttab values (1,1,'pr1')
, (2,3,'pr3') --this I added to get the result
insert into #Statustab values (1,'approve by manager'),(2,'approve by CC manager'),(3,'approve by designer'),(4,'approve by BU head')
insert into #ApprovalStatustab values (1,1,3,'jan 1 2015'),(1,2,3,'jan 3 2015'),(1,4,4,'jan 5 2015')
,(2,2,3,'jan 5 2015') --this I added to get the result
Select
distinct
P.PRNR,
EmployeeName
,Statusmsg
from #Employeetab as E
inner join #PurchaseRequesttab AS P ON E.Employeeid = p.Employeeid
inner join #ApprovalStatustab as A ON P.PRID = A.PRID
--and a.Employeeid = e.Employeeid --this is added for distinct result too
inner join #Statustab as S on A.StatusID = S.StatusID
Your status msg has to be different because your status id is different and they have different messages... if they had the same message you would have 1 row.
Ensure the column PRNR in PurchaseRequesttab is unique (like PRID column).
I have a table like this
Table A:
Id Count
1 4
1 16
1 8
2 10
2 15
3 18
etc
Table B:
1 sample1.file
2 sample2.file
3 sample3.file
TABLE C:
Count fileNumber
16 1234
4 2345
15 3456
18 4567
and so on...
What I want is this
1 sample1.file 1234
2 sample2.file 3456
3 sample3.file 4567
To get the max value from table A I used
Select MAX (Count) from A where Id='1'
This works well but my problem is when combining data with another table.
When I join Table B and Table A, I need to get the MAX for all Ids and in my query I dont know what Id is.
This is my query
SELECT B.*,C.*
JOIN A on A.Id = B.ID
JOIN C on A.id = B.ID
WHERE (SELECT MAX(COUNT)
FROM A
WHERE Id = <what goes here????>)
To summarise, what I want is Values from Table B, FileNumber from Table c (where the count is Max for ID from table A).
UPDATE: COrrecting table C above. Looks like I need Table A.
I think this is the query you're looking for:
select b.*, c.filenumber from b
join (
select id, max(count) as count from a
group by id
) as NewA on b.id = NewA.id
join c on NewA.count = c.count
However, you should take into account that I don't get why for id=1 in tableA you choose the 16 to match against table C (which is the max) and for id=2 in tableA you choose the 10 to match against table C (which is the min). I assumed you meant the max in both cases.
Edit:
I see you've updated tableA data. The query results in this, given the previous data:
+----+---------------+------------+
| ID | FILENAME | FILENUMBER |
+----+---------------+------------+
| 1 | sample1.file | 1234 |
| 2 | sample2.file | 3456 |
| 3 | sample3.file | 4567 |
+----+---------------+------------+
Here is a working example
Using Mosty’s working example (renaming the keyword count to cnt for a column name), this is another approach:
with abc as (
select
a.id,
a.cnt,
rank() over (
partition by a.id
order by cnt desc
) as rk,
b.filename
from a join b on a.id = b.id
)
select
abc.id, abc.filename, c.filenumber
from abc join c
on c.cnt = abc.cnt
where rk = 1;
select
PreMax.ID,
B.FileName,
C2.FileNumber
from
( select C.id, max( C.count ) maxPerID
from TableC C
group by C.ID
order by C.ID ) PreMax
JOIN TableC C2
on PreMax.ID = C2.ID
AND PreMax.maxPerID = C2.Count
JOIN TableB B
on PreMax.ID = B.ID
