I get an error with query
UPDATE schema1.table1 t
SET (a1, a2, a3, a4, a5) = (
SELECT DISTINCT tt.a1, tt.a2, tt.a3, tt.a4, tt.a5
FROM schema1.table2 tt
WHERE tt.is_flg = 1
AND tt.some_cnt > 0
AND (t.date1 BETWEEN tt.date1 AND tt.date2)
AND tt.id = t.id
);
More than one row returned by a subquery used as an expression
How can I transform query to catch rows which give this error?
UPD: I transform it with with but I don't sure that result set is correct, because query with update use 251 rows and query with with and without distinct use 465 rows (with & distinct 51 rows)
with h as (select * from schema1.table1)
select DISTINCT tt.a1, tt.a2, tt.a3, tt.a4, tt.a5
FROM schema1.table2 tt INNER JOIN h ON tt.id = t.id
WHERE tt.is_flg = 1
AND tt.some_cnt > 0
AND (t.date1 BETWEEN tt.date1 AND tt.date2)

I am trying to get the max date by account from 3 different tables and view those dates side by side. I created a separate query for each table, merged the results with UNION ALL, and then wrapped all that in a PIVOT.
The first 2 sections in the link/pic below show what I have been able to accomplish and the 3rd section is what I would like to do.
Query results by step
How can I get the results from 2 of the tables to repeat? Is that possible?

Everything is possible. You only need a window function to make the value repeat across rows w/o data.
--Assuming current query is QC
With QC as (
...
)
select code, account, grouping,
--cash,
first_value(cash) over (partition by code, account order by grouping asc rows unbounded preceding) as cash_repeat,
perf,
--pos,
first_value(pos) over (partition by code, account order by grouping asc rows unbounded preceding) as pos_repeat
from QC
;
See first_value() help here: https://docs.oracle.com/en/database/oracle/oracle-database/19/sqlrf/FIRST_VALUE.html#GUID-D454EC3F-370C-4C64-9B11-33FCB10D95EC
I am working with SQL Server 2008 Report service. I have to try to split string values in different columns in same row in expression but I can't get the excepted output. I have provided input and output details. I have to split values by space (" ") and ("-").
Input :
Sample 1:
ASY-LOS,SLD,ME,A1,A5,J4A,J4B,J4O,J4P,J4S,J4T,J7,J10,J2A,J2,S2,S3,S3T,S3S,E2,E2F,E6,T6,8,SB1,E1S,OTH AS2-J4A,J4B,J4O,J4P,J4S,J4T,J7,J1O,J2A,S2,S3,J2,T6,T8,E2,E4,E6,SLD,SB1,OTH
Sample 2:
A1 A2 A3 A5 D2 D3 D6 E2 E4 E5 E6 EOW LH LL LOS OTH P8 PH PL PZ-1,2,T1,T2,T3 R2-C,E,A RH RL S1 S2-D S3
Output should be:
Thank you.
I wrote this before I saw your comment about having to do it in the report. If you can explain why you cannot do this in the dataset query then there may be a way around that.
Anyway, here's one way of doing this using SQL
DECLARE #t table (RowN int identity (1,1), sample varchar(500))
INSERT INTO #t (sample) SELECT 'ASY-LOS,SLD,ME,A1,A5,J4A,J4B,J4O,J4P,J4S,J4T,J7,J10,J2A,J2,S2,S3,S3T,S3S,E2,E2F,E6,T6,8,SB1,E1S,OTH AS2-J4A,J4B,J4O,J4P,J4S,J4T,J7,J1O,J2A,S2,S3,J2,T6,T8,E2,E4,E6,SLD,SB1,OTH'
INSERT INTO #t (sample) SELECT 'A1 A2 A3 A5 D2 D3 D6 E2 E4 E5 E6 EOW LH LL LOS OTH P8 PH PL PZ-1,2,T1,T2,T3 R2-C,E,A RH RL S1 S2-D S3'
drop table if exists #s1
SELECT RowN, sample, SampleIdx = idx, SampleValue = [Value]
into #s1
from #t t
CROSS APPLY
spring..fn_Split(sample, ' ') as x
drop table if exists #s2
SELECT
s1.*
, s2idx = Idx
, s2Value = [Value]
into #s2
FROM #s1 s1
CROSS APPLY spring..fn_Split(SampleValue, '-')
SELECT SampleKey = [1],
Output = [2] FROM #s2
PIVOT (
MAX(s2Value)
FOR s2Idx IN ([1],[2])
) p
This produced the following results
If you do not have a split function, here is the script to create the one I use
CREATE FUNCTION [dbo].[fn_Split]
/* Define I/O parameters WARNING! DO NOT USE MAX DATA-TYPES HERE! IT WILL KILL PERFORMANCE! */

,#pDelimiter CHAR(1)

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 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
I want to compare content of 15 columns in two rows.
I am using db2 9 with jdbc.
Can I use a sql to get a result like "match or not match"
And How can I get columns differs?
You can use the EXCEPT operator to do this.
In the example below, I'm using common table expressions to fetch a the single rows (assuming, in this case, that id is the primary key.
with r1 as (select c1, c2, ..., c15 from t where id = 1),
r2 as (select c1, c2, ..., c15 from t where id = 2)
select * from r1
except
select * from r2
If this returns 0 rows, then the rows are identical. If it returns a row, then the two rows differ.
If you really want the result to be 'MATCH' or 'NOT MATCH':
with r1 as (select c1, c2, ..., c15 from t where id = 1),
r2 as (select c1, c2, ..., c15 from t where id = 2),
rs as (select * from r1 except select * from r2)
select
case when count(*) = 0 then 'MATCH'
else 'NOT MATCH'
end as comparison
from
rs;
