In postgresql I got 4 tables
Table A:
-----------
a_id
a_date
Table B
-----------
a_id b_id
Table C:
-------------------
c_id
b_id
invoice_number
Table D
-------------------
d_id
invoice_number
value_D
Multiple records have value_D
I would like to select Table A, Table B, Table C and Table D, where a_date BETWEEN X AND Y.
However, I would also like to select all the other value_D that are not included in my selection (so A innerjoin B innerjoin C full outerjoin D)
my code
SELECT
Table A, Table B, Table C, Table D
FROM
Table A
JOIN
Table B ON A.a_id = B.a_id
JOIN
Table C ON B.b_id = C.b_id
FULL OUTER JOIN
Table D ON C.invoice_number = D.invoice_number
WHERE
A.a_date BETWEEN X AND Y;
It only shows D.value_d for the A.a_id, where A.a_date BETWEEN X and Y.
I would like however that D.value_d would also be shown for A.a_id, where A.a_date is also other.
I am kinda a newbie, so hopefully it is understandable and you could help me.
Thanks in advance
You can also add more conditions to the Where clause, for example:
"a_date BETWEEN X AND Y OR a_date > '2015-04-21'". This will retrieve the union of both conditions.
Regards
I think I solved it.
SELECT Table A, Table B, Table C, Table D
FROM Table A
JOIN Table B ON A.a_id = B.a_id
JOIN Table C ON B.b_id = C.b_id
JOIN Table D ON C.invoice_number = D.invoice_number
WHERE A.a_date BETWEEN X AND Y OR
D.value_D IN (SELECT D.value_D
FROM Table D
JOIN Table C ON D.invoice_number on C.invoice_number
JOIN Table B ON C.b_id = B.b_id
JOIN Table A ON B.a_id = A.a_id
WHERE A.a_date BETWEEN X AND Y);
Thank you all for the help guys!

I've got multiple tables
I made my query like this :
SELECT a.creation, b.caseno, c.instanceno
FROM TableB b
JOIN TableA a
ON a.caseno = b.caseno
JOIN TableC c
ON c.caseno = b.caseno
WHERE a.creation BETWEEN '2021-01-01' AND '2021-12-31'
I've got TableD who contains the following column
| InstanceNo | Position | Creation | TaskNo |
The idea is to add a new colum (result) on my query.
If instance from c.instanceno exist on tableD and taskno is 30 or 20, in that case i would like the d.creation but for the max(position).
If not the value null is enough for the column result.
SELECT a.creation, b.caseno, c.instanceno, d.creation
FROM TableB b
JOIN TableA a
ON a.caseno = b.caseno
JOIN TableC c
ON c.caseno = b.caseno
LEFT JOIN (SELECT MAX(position) position, instanceno, creation, taskno FROM TableD GROUP BY instanceno, creation, taskno) d
ON d.instanceno = c.instanceno
AND d.taskno in (20,30)
WHERE a.creation BETWEEN '2021-01-01' AND '2021-12-31'
I have a Table which has 2 fields say A,B. Suppose A has values a1,a2.
Corresponding records for a1 in B are 1,2,3,x,y,z.
Corresponding records for a2 in B are 1,2,3,4,d,e,f
I need a a query to be written in DB2, so that it will fetch the common records in B for each record in A (a1 and a2).
So here the output would be :
A B
a1 1
a1 2
a1 3
a2 1
a2 2
a2 3
Can someone please help on this?
Try something like:
SELECT A, B
FROM Table t1
WHERE (SELECT COUNT(*) FROM Table t2 WHERE t2.B = t1.B)
= (SELECT COUNT(DISTINCT t3.A) FROM Table t3)
ORDER BY A, B
This might not be 100% accurate as I can't test it out in DB2 so you might have to tweak the query a little bit to make it work.
with t(num) as (select count(distinct A) from table)
select t1.A, t1.B
from table t1, table t2, t
where t1.B = t2.B
group by t1.A, t1.B, num
having count(*) = num
Basically, the idea is to join the same table with column B and filter out just the ones that match exactly the same number of times as the number of elements in column A, which indicates that it is a common record out of all the A values.
I have two tables
Table A Table B
-------- ---------
a b c a b c
a b c a b c
a b c a b c
e f g a b c
h i j e f g
k l m k l m
k l m
x y z
s t u
a b c
a b c
Now i want to remove rows in Table B matching on column 1, 2 and 3 with table A where the count of each duplicate row in Table B should be less than or equal to table A.
So the output should be
Table A Table B
-------- ---------
a b c a b c
a b c a b c
a b c a b c
e f g e f g
h i j k l m
k l m x y z
s t u
I have tried using inner join and intersect but failed to get the desired result.
Try:
DELETE FROM tableB
WHERE ctid IN (
SELECT BB.ctid
FROM (
SELECT a, b, c, count(*) cnt
FROM tablea
GROUP BY a, b, c
) AA
JOIN (
SELECT ctid,
a, b, c,
row_number() over (partition by a,b,c) cnt
FROM tableb
) BB
ON AA.a = BB.a
AND AA.b = BB.b
AND AA.c = BB.c
AND AA.cnt < BB.cnt
)
demo: http://sqlfiddle.com/#!12/73e99/1
I think if table isn't big the simply way is to delete all rows from TableB which exist in TableA and then insert TableA into TableB. Another ways IMHO are required at least a primary key in TableB.
DELETE FROM TableB
WHERE EXISTS(SELECT * FROM TableA
WHERE C1=TableA.C1
AND C2=TableA.C2
AND C3=TableA.C3) ;
INSERT INTO TableB SELECT * FROM TableA;
In my procedure I have two tables with the same data. I go through my first table through a cursor. Which compares with the second table that I find much the same data. What if, for example in my table_1 I have ten in my data and I have 12 data table2 how to detect missing data in my two table_1 which is traversed by the cursor?
Thx.
Sounds very much like you'd be better off using the MINUS operator.
SELECT a, b, c
FROM table1
MINUS
SELECT a, b, c
FROM table2
This will show you all results that exist in table1 which are not present in table2. In order to show discrepancies both ways, you could do something like this:
SELECT z.*, 'In table1, not in table2' problem_description
FROM (
SELECT a, b, c
FROM table1
MINUS
SELECT a, b, c
FROM table2
) z
UNION ALL
SELECT z.*, 'In table2, not in table1' problem_description
FROM (
SELECT a, b, c
FROM table2
MINUS
SELECT a, b, c
FROM table1
) z

I have a SQL Server table. Now this table has columns like primary key Id, A, B, C, D, E, F, G
Now I want to select rows from this table like this
A=A, B=B, C=C, D=D and G > 132
So I am trying to select rows from this table which rows A,B,C,D columns has same data and G column data > 132.
So how can I do that ? Thank you.
I tried this query but returning same Id rows
SELECT TableA.Id,TableA.UserId,TableA.MaximumHp,TableA.Attack,TableA.Defense,TableA.SpAttack,TableA.SpDefense,TableA.Speed
FROM myTable as TableA
Inner Join myTable as TableB on
TableA.MaximumHp = TableB.MaximumHp
AND TableA.Attack = TableB.Attack
AND TableA.Defense = TableB.Defense
AND TableA.SpAttack = TableB.SpAttack
AND TableA.SpDefense = TableB.SpDefense
AND TableA.Speed = TableB.Speed
AND TableA.Id != TableB.Id
SQL Server 2008 R2
Sounds like you want to join the table to itself
SELECT *
FROM Table t1
Inner Join Table t2 on t1.A = t2.A
AND t1.B = t2.B
AND t1.C = t2.C
AND t1.D = t2.D
AND t1.G > 132
AND t1.ID <> t2.ID
I THINK what you mean is duplicates. Tell me if this is what you are looking for.
SELECT [Table].A, [Table].B, [Table].C, [Table].D, [Table].E, [Table].F, [Table].G
FROM [Table] LEFT JOIN (SELECT A, B, C, D FROM [Table]
GROUP BY A, B, C, D
HAVING count(*) > 1)
AS sub ON ([Table].A=sub.A) AND ([Table].B=sub.B) AND ([Table].C=sub.C) AND ([Table].D=sub.D)
WHERE G>132 and sub.A is not null;
This will give you all the rows where a,b,c, and D are equal to another row in the table...and G > 132
