I have below table :- table1
ID Desc
1 ABC
2 DEF
3 GHI
3 JKL
4 MNO
4 PQR
4 STU
I want to show data as :-
ID Desc
1 ABC
2 DEF
3 GHI
JKL
4 MNO
PQR
STU
I tried to make it as :-
select distinct ID , Desc from table1
But its not working.
In Sql server its possible :
Select distinct ID , stuff((SELECT ','+Description FROM #a a WHERE
t.id=a.id for xml path('')),1,1,'') Description
from #a T
Output : Id Desc
1 ABC
2 DEF
3 GHI,JKL
4 MNO,PQR,STU
for what i know you can't, you have to modify the look of your table after the request (for example in html)
This needs to be handled in presentation layer but you can query as below:
Select Case when Row_Number() over(Partition by Id order by Id) = 1 then Id else Null end as Id,
[Desc] from #data
Below query will generate the desired result.
SELECT CASE WHEN (Rank() Over(ORDER BY id ASC)) = (Row_Number() Over (ORDER BY id ASC)) THEN id ELSE NULL END as ID, desc FROM table1

I m using pivot and unpivot but I dot get expected output
Here is my sample data set
Table 1
id c_code
-----------------
123 1
456 1
Table 2
id c_code i_t_code i_code
----------------------
123 1 TWinc 10
123 1 TBinc 20
123 1 TSinc 30
Table 3
i_code i_t_code i_name
------------------------------
10 TWinc abc
20 TBinc xyz
30 TSinc pqr
Here is my query
Query
select * from (
select id,inc,i_t_code from (
select a.id,b.i_name,cast(b.i_code AS
VARCHAR(128)) as i_code,b.i_t_code
from
table_1 a
join
table_2 b
on a.id= b.id
and
a.c_code = b.c_code
join
tabl_3 c on c.i_code = b.i_code
and
c.i_t_code = b.i_t_code
on a.i_code = b.i_code
) d
Unpivot
(
inc for details in (i_name,i_code)
) as unpt) as uppt_res
PIVOT
(
max(inc)
FOR [i_t_code] IN ([TWinc],[TBinc],[TSinc])
) AS P
Expected output:
id TWinc_n TWinc_c TBinc_n TBinc_c TSinc_n TSinc_c
------------------------------------------------------------
123 abc 10 xyz 20 pqr 30
Actual output:
id TWinc TBinc TSinc
------------------------------------
123 abc xyz pqr
How can do this ??
It is possible using pivot or any other solution is there
can anyone help to fix this ?
You're going to have to give your data some variation if you want to stop pivot from compressing equal data items together when it's converting row data into column names and picking the max(inc) - probably easiest to do by changing the contents of the unpivoted data, tacking on a row number:
SELECT * FROM
(
select stoneid, inc, CONCAT(inclusion_type_id, ROW_NUMBER()OVER(PARTITION BY inclusion_type_id ORDER BY inc)) as inclusion_type_id FROM
(
select
a.stoneid,
b.inclusion_name,
cast(b.inclusion_code AS VARCHAR(128)) as inclusion_code,
b.inclusion_type_id,
b.inclusion_type_code
from
PACKET.STONE_LAB_INCLUSIONS a
inner join
MASTER.INCLUSION_MASTER b
on
a.inclusion_code = b.inclusion_code and
a.inclusion_type_code = b.inclusion_type_code
inner join
packet.stone_details c
on
c.stoneid = a.stoneid and
c.certificate_code = a.certificate_code
) d
UNPIVOT(inc for details in (inclusion_name,inclusion_code)) as unpt
) uppt_res
PIVOT
(
MAX(inc)
FOR [inclusion_type_id] IN ([TWinc1],[TWinc2],[TBinc1],[TBinc2],[TSinc1],[TSinc2])
) AS P
If you're desperate to have column names the same, you can alias the results of this query rather than select *
How do I simply switch Rows with Column in SQL with count? Is there any way to do?
Actually i want against each unique mobile no with count and product name side by side means if two mobile no in table then count = 2 and side of that two product1,product2 shows in output.
ie turn this result:
Srno Name| Mobile| Count | ProductName
1 xyz 1234 1 LNM
2 PQR 5678 1 VCD
3 xyz 1234 1 KLM
4 PQR 5678 1 NMG
into this:
Srno Name| Mobile| Count | ProductName1 | ProductName2
1 xyz 1234 2 LNM KLM
2 PQR 5678 2 VCD NMG
If you have a limited products then you use row_number() & do conditional aggregation :
select min(srno) as srno, name, Mobile, count(*) as cnt,
max(case when seq = 1 then ProductName end) as ProductName1,
max(case when seq = 2 then ProductName end) as ProductName2
from (select t.*,
row_number() over (partition by name, Mobile order by srno) as seq
from table t
) t
group by name, Mobile;
Try this:
SET #row_number = 0;
SELECT
(#row_number:=#row_number + 1) AS Srno,
T1.name,
T1.Mobile,
SUM(T1.xCount + T2.xCount) as cnt,
max(T1.ProductName) as Product1,
max(T2.ProductName) as Product2
FROM Table1 as T1
LEFT JOIN Table1 AS T2 ON T1.name = T2.name
AND T2.srno > T1.srno
GROUP BY T1.name, T1.Mobile
ORDER BY Srno
ID UserId Name Amount RewardId
----------------------------
1 1 James 10.00 1
2 1 James 10.00 2
3 1 James 10.00 3
4 2 Dave 20.00 1
5 2 Dave 20.00 3
6 3 Lim 15.00 2
I'm trying to insert to another table, and this is the result that i'm struggling with:
Tbl1ID RewardId
------------------
1 1
1 2
1 3
4 1
4 3
6 2
I'm trying to get the MIN(ID) of each person and select all the RewardId that belong to that person.
You could do a simple self join to get the minimum id value per userid/rewardid combination;
SELECT MIN(a.id) Tbl1ID, b.RewardId
FROM mytable a
JOIN mytable b
ON a.name = b.name
GROUP BY b.userid, b.rewardid
ORDER BY tbl1id, rewardid;
An SQLfiddle to test with.
If you are running SQL Server 2008+, you can simplify it by using Window Function.
INSERT INTO AnotherTable (Tbl1ID, RewardID)
SELECT MIN(ID) OVER (PARTITION BY Name),
RewardID
FROM SourceTable
SQLFiddle Demo
Try this
SELECT tbl1id,RewardID From
table1 S JOIN
(
SELECT MIN(ID) as tbl1id,Name FROM table1 GROUP BY Name
) T ON T.Name = S.Name
ORDER BY tbl1id
FIDDLE DEMO
Output:
Tbl1ID RewardId
----------------
1 1
1 2
1 3
4 1
4 3
6 2
If you want insert into new table then try this out
Insert into Newtable (tbl1id,RewardID)
SELECT tbl1id,RewardID from
table1 S JOIN
(
SELECT MIN(ID) as tbl1id,Name
FROM table1
GROUP BY Name
) T ON T.Name = S.Name
ORDER BY tbl1id;
FIDDLE DEMO
Table name is group. Column name is groupno,name,grouprefno,detail,undergroupno
Sample data of group
groupno name grouprefno detail undergroupno
1 A 001 abc 0
2 B 002 cde 0
3 AA 001001 abc 1
4 AC 001002 abc 1
5 AAA 001001001 DDD 3
6 DDD 001001002 ddd 3
7 www 001002001 223 4
8 eee 001002002 222 4
Now i want to get rows which name's are AA, AC and which are comes under the AA,AC
So i tried like this
select no from group where substring(grouprefno,1,
(select length(grouprefno) from group where name ='AA'
))=(select grouprefno from group
where name ='AA' ) union all select no from group where substring(grouprefno,1,
(select length(grouprefno) from group where name ='AC'
))=(select grouprefno from group
where groupname ='AC' )
Its Work Fine, But i want another solution because it has 2 sub query's in side of single query. It has any other feasible solution?
Am using postgresql 9.1
Try:
WITH q AS(
SELECT *
FROM Table1
WHERE name IN ('AA','AC')
)
SELECT * FROM q
UNION ALL
SELECT * FROM Table1 t
WHERE t.undergroupno IN (
SELECT groupno FROM q
)

I have a table like following:
GroupID ParentID Type
1 ABC IND
1 ABC IND
1 CDE ORD
1 EFG STD
2 ZZZ IND
2 ZZZ IND
2 ZZZ IND
3 YYY COR
3 YYY COR
I need to exclude those records that are in the same group, having the same parent ID and the type is IND or COR. But I need to keep those groups that have different parent ID and the type is not IND or COR.
So the result I want to get would be the following:
GroupID ParentID Type
1 ABC IND
1 ABC IND
1 CDE ORD
1 EFG STD
Somehow I am thinking to use
Rank () over(partition by GroupID order by ParentID), but it won't give me the results that I want.
Any thoughts? PS: This table has 5 Million+ records. Looking for the effective way to deal with it.
Thanks
The following gives you a list of the groupIDs you want to exclude
SELECT GroupID
FROM
(
SELECT GroupID,
COUNT(DISTINCT ParentID) AS PCount, COUNT(DISTINCT TypeCode) as TCount,
MAX(TypeCode) AS tCode
FROM tablename
GROUP BY GroupID
) t
WHERE PCount = 1 AND TCount = 1
AND (tCode = 'IND' OR tCode = 'COR')
Now select everything else
SELECT *
FROM tableName
WHERE GroupID not in (
SELECT GroupID
FROM
(
SELECT GroupID,
COUNT(DISTINCT ParentID) AS PCount, COUNT(DISTINCT TypeCode) as TCount,
MAX(TypeCode) AS tCode
FROM tablename
GROUP BY GroupID
) t
WHERE PCount = 1 AND TCount = 1
AND (tCode = 'IND' OR tCode = 'COR')
)

How is
1 ABC IND
in result set? here type is IND and you mentioned the result set should not have type IND or COR?
