Assume all value columns have the same datatype. I would like the highest of all values with the id in the results of a SELECT query.
Table Structure:
table_a: id, value1, value2, value3, value4, value5
Example data:
id, value1, value2, value3, value4, value5
2, 125, 256, 133, 400, 67
3, 14, 14, 14, 3, 6
4, 325, 441, 441, 975, 3
Example desired results:
id, highest_value
2, 400
3, 14
4, 975
I started down the path of a CASE statement but that got messy fast. I tired a sub-select but failed in getting that to work. Is there a clean way to compare several column values to each other?
In this case greatest function will do the work.
with t1(id1, val1, val2, val3, val4, val5) as
(
select 2, 125, 256, 133, 400, 67 from dual union all
select 3, 14, 14, 14, 3, 6 from dual union all
select 4, 325, 441, 441, 975, 3 from dual
)
select id1
, greatest(val1, val2, val3, val4, val5) Res
from t1
Result:
Id1 Res

Good Day. I have a new Apex database For a dart league.
I have a lot of work to do! but cant combine (with code - I have the right numbers on the interactive grid by using the sum function) I have the following code and results that work for each player, which I need, But cannot get the summed of average for each player.... this matters when creating a handicap.
select Team, name,
COUNT(WEEK) * 3 GAMES,
sum(game_1) + sum(game_2) + sum(game_3) points,
Round(((sum(game_1) + sum(game_2) + sum(game_3)) / ((COUNT(WEEK) * 3))), 2) Average
from score_tbl
group by Team, name
order by 1

I am trying to figure out the code to sum the Averages for each player by team.
Team Average Handicap
Team 1 64.17
Team 2 55.33
etc..
then, if possible compare those averages to find the highest average. Then take the Highest avg - (each Team) * 90%.
I am trying to figure out the code to sum the Averages for each player by team.
Wrap the expression for generating the average in an analytic SUM for each team partition:
SELECT team,
name,
COUNT(WEEK) * 3 AS games,
SUM(game_1 + game_2 + game_3) AS points,
ROUND(AVG(game_1 + game_2 + game_3) / 3, 2) AS average,
ROUND(SUM(AVG(game_1 + game_2 + game_3) / 3) OVER (PARTITION BY team), 2)
AS total_average
FROM score_tbl
GROUP BY
team, name
ORDER BY
team;
Which, for the sample data:
CREATE TABLE score_tbl(team, name, week, game_1, game_2, game_3) AS
SELECT 1, 'B Tyler', 1, 24, 24, 23 FROM DUAL UNION ALL
SELECT 1, 'Blind', 1, 18, 18, 18 FROM DUAL UNION ALL
SELECT 1, 'Jim V', 1, 9, 8, 9.5 FROM DUAL UNION ALL
SELECT 1, 'KC M', 1, 14, 14, 13 FROM DUAL UNION ALL
SELECT 2, 'J Spass', 1, 17, 17, 17 FROM DUAL UNION ALL
SELECT 2, 'Randy B', 1, 18, 17, 17.5 FROM DUAL UNION ALL
SELECT 2, 'Tim Ketz', 1, 13, 12, 12 FROM DUAL UNION ALL
SELECT 2, 'Todd Lapan', 1, 9, 8, 8.5 FROM DUAL UNION ALL
SELECT 1, 'B Tyler', 1, 24, 24, 23 FROM DUAL UNION ALL
SELECT 1, 'Blind', 1, 18, 18, 18 FROM DUAL UNION ALL
SELECT 1, 'Jim V', 1, 9, 8, 9.5 FROM DUAL UNION ALL
SELECT 1, 'KC M', 1, 14, 14, 13 FROM DUAL UNION ALL
SELECT 2, 'J Spass', 1, 17, 17, 17 FROM DUAL UNION ALL
SELECT 2, 'Randy B', 1, 18, 17, 17.5 FROM DUAL UNION ALL
SELECT 2, 'Tim Ketz', 1, 13, 12, 12 FROM DUAL UNION ALL
SELECT 2, 'Todd Lapan', 1, 9, 8, 8.5 FROM DUAL;

can you please explain why the error ORA-00918 is generated while executing this query
INSERT INTO CLG_TEST_2 (CLG_TEST_2.record_id, CLG_TEST_2.chain_id,
CLG_TEST_2.chain_n,
CLG_TEST_2.contact_info)
select * from (
SELECT 1, 1, 0, '2222' from dual UNION ALL
SELECT 2, 2, 0, '4444' from dual UNION ALL
SELECT 3, 3, 0, '6666' from dual
)
Error at line 1
ORA-00918: column ambiguously defined
Script Terminated on line 2.
The issue is in the fact that you are using a select * over a query without giving aliases to the columns; this will work:
INSERT INTO CLG_TEST_2 (CLG_TEST_2.record_id,
CLG_TEST_2.chain_id,
CLG_TEST_2.chain_n,
CLG_TEST_2.contact_info)
select *
from (
SELECT 1 a, 1 b, 0 c, '2222' d from dual UNION ALL
SELECT 2 , 2 , 0 , '4444' from dual UNION ALL
SELECT 3 , 3 , 0 , '6666' from dual
)
However, you can simplify your code:
INSERT INTO CLG_TEST_2 (record_id, chain_id, chain_n, contact_info)
SELECT 1, 1, 0, '2222' from dual UNION ALL
SELECT 2, 2, 0, '4444' from dual UNION ALL
SELECT 3, 3, 0, '6666' from dual
Something more about the reason of the error.
Your code:
SQL> INSERT INTO CLG_TEST_2 (
2 CLG_TEST_2.record_id,
3 CLG_TEST_2.chain_id,
4 CLG_TEST_2.chain_n,
5 CLG_TEST_2.contact_info)
6 select * from (
7 SELECT 1, 1, 0, '2222' from dual UNION ALL
8 SELECT 2, 2, 0, '4444' from dual UNION ALL
9 SELECT 3, 3, 0, '6666' from dual
10 );
select * from (
*
ERROR at line 6:
ORA-00918: column ambiguously defined
Slightly different:
SQL> INSERT INTO CLG_TEST_2 (
2 CLG_TEST_2.record_id,
3 CLG_TEST_2.chain_id,
4 CLG_TEST_2.chain_n,
5 CLG_TEST_2.contact_info)
6 select * from (
7 SELECT 1, 2, 0, '2222' from dual UNION ALL
8 SELECT 2, 2, 0, '4444' from dual UNION ALL
9 SELECT 3, 3, 0, '6666' from dual
10 );
3 rows created.
What's different?
In the first row, I changed
SELECT 1, 1, 0, '2222' --> SELECT 1, 2, 0, '2222'
^ ^
The reason:
SQL> SELECT 1, 2, 0, '2222' from dual UNION ALL
2 SELECT 2, 2, 0, '4444' from dual UNION ALL
3 SELECT 3, 3, 0, '6666' from dual;
1 2 0 '222
---------- ---------- ---------- ----
1 2 0 2222
2 2 0 4444
3 3 0 6666
SQL> SELECT 1, 1, 0, '2222' from dual UNION ALL
2 SELECT 2, 2, 0, '4444' from dual UNION ALL
3 SELECT 3, 3, 0, '6666' from dual;
1 1 0 '222
---------- ---------- ---------- ----
1 1 0 2222
2 2 0 4444
3 3 0 6666

Here you have two columns with the same alias '1', and this is confusing for the external select *.
Also, a direct-path insert is something different
I don't see any "Direct-Path" insert. Anyway, try this one
INSERT INTO CLG_TEST_2 (CLG_TEST_2.record_id, CLG_TEST_2.chain_id,
CLG_TEST_2.chain_n,
CLG_TEST_2.contact_info)
SELECT 1, 1, 0, '2222' from dual UNION ALL
SELECT 2, 2, 0, '4444' from dual UNION ALL
SELECT 3, 3, 0, '6666' from dual
btw, why do you use string from numbers?
I have a table including CONTRACT_ID, ADDENDUM_ID and PAYMENT_MONTH (payment dates of a yearly contract).
Everytime an update occurs for any reason in the system:
ADDENDUM_ID udates as +1
PAYMENT_MONTH records are duplicated for the remaining months
In attached picture I tried to explain in detail using an example (a contract with 3 updates).
The question is how to write a query to get a summary table ignoring the duplicated but unnecessary records (grey filled ones) because of a new update on addendum column.
Please note that there are hundreds of contracts in the original table, while the example contains only one.
Thanks in advance.
If I correctly understand your desired output, maybe this can help:
with test(contract_id, addendum_id, payment_month) as
(
select 155, 1, 1 from dual union all
select 155, 1, 2 from dual union all
select 155, 1, 3 from dual union all
select 155, 1, 4 from dual union all
select 155, 1, 5 from dual union all
select 155, 1, 6 from dual union all
select 155, 1, 7 from dual union all
select 155, 1, 8 from dual union all
select 155, 1, 9 from dual union all
select 155, 1, 10 from dual union all
select 155, 1, 11 from dual union all
select 155, 1, 12 from dual union all
select 155, 2, 5 from dual union all
select 155, 2, 6 from dual union all
select 155, 2, 7 from dual union all
select 155, 2, 8 from dual union all
select 155, 2, 9 from dual union all
select 155, 2, 10 from dual union all
select 155, 2, 11 from dual union all
select 155, 2, 12 from dual union all
select 155, 3, 10 from dual union all
select 155, 3, 11 from dual union all
select 155, 3, 12 from dual
)
select contract_id, addendum_id, payment_month from (
select
max(addendum_id) over ( partition by payment_month) as max_addendum_id,
contract_id, payment_month, addendum_id
from test
)
where max_addendum_id = addendum_id
order by 1, 2, 3
I have 3 columns a,b,c in table.i need to find the duplicates for the columns a & b but with distinct value in c column.
Maybe you need something like this:
with test(a, b, c) as (
select 1, 2, 10 from dual union all
select 1, 2, 20 from dual union all
select 4, 5, 30 from dual union all
select 4, 5, 30 from dual union all
select 3, 2, 3 from dual union all
select 6, 2, 2 from dual
)
select a, b
from test
group by a,b
having count(distinct c) > 1
That is, you need to aggregate for A,B, but only keeping pairs for which there are more DISTINCT values for column C
If i give this query,
Select 1,2,3,4,5,6,7,8,9 from dual;
It will look like this
1 2 3 4 5 6 7 8 9 - column names
1 2 3 4 5 6 7 8 9 - Associated values
But i want to show like this
1
2
3
4
5
6
7
8
9
I don't know how to do this with dual table
"Unpivot version":
select val from (select 1, 2, 3, 4, 5, 6, 7, 8, 9 from dual)
unpivot (val for tmp in ("1", "2", "3", "4", "5", "6", "7", "8", "9"))
Simpler alternative giving the same results:
select * from table(sys.odcinumberlist(1, 2, 3, 4, 5, 6, 7, 8, 9))
Just use union all:
select 1 as name from dual union all
select 2 as name from dual union all
select 3 as name from dual union all
select 4 as name from dual union all
select 5 as name from dual union all
select 6 as name from dual union all
select 7 as name from dual union all
select 8 as name from dual union all
select 9 as name from dual;
