Optimize Group by Hour Query

Optimize Group by Hour Query - sql

Please help to optimize my query. It looks too bulky.
I guess there is a better way to work with hours (datetime) in sql
There is a table dauditnew that is populated and population datetime is stored inside auditdate column.
Query returns rows count by hour.
SELECT t.Hour, COUNT(t.Hour) as Count FROM dauditnew d,
(SELECT 0 as Hour FROM DUAL UNION
SELECT 1 FROM DUAL UNION
SELECT 2 FROM DUAL UNION
SELECT 3 FROM DUAL UNION
SELECT 4 FROM DUAL UNION
SELECT 5 FROM DUAL UNION
SELECT 6 FROM DUAL UNION
SELECT 7 FROM DUAL UNION
SELECT 8 FROM DUAL UNION
SELECT 9 FROM DUAL UNION
SELECT 10 FROM DUAL UNION
SELECT 11 FROM DUAL UNION
SELECT 12 FROM DUAL UNION
SELECT 13 FROM DUAL UNION
SELECT 14 FROM DUAL UNION
SELECT 15 FROM DUAL UNION
SELECT 16 FROM DUAL UNION
SELECT 17 FROM DUAL UNION
SELECT 18 FROM DUAL UNION
SELECT 19 FROM DUAL UNION
SELECT 20 FROM DUAL UNION
SELECT 21 FROM DUAL UNION
SELECT 22 FROM DUAL UNION
SELECT 23 FROM DUAL) t
where
d.auditdate >= TO_DATE('25.04.2017 ' || t.Hour, 'dd.mm.yyyy HH24') and
d.auditdate <= TO_DATE('25.04.2017 ' || t.Hour || '_59_59', 'dd.mm.yyyy HH24_MI_SS')
group by t.Hour

You want to start with something like this:
select trunc(d.auditdate, 'HH24') as hh, count(*)
from dauditnew d
where d.auditdate >= '2017-04-25' and d.auditdate < '2017-04-26'
group by trunc(d.auditdate, 'HH24')
order by hh;
If this misses hours, then you can use a left join with this as a subquery.

Is there any alternative to use MYSQL's ADDDATE() in ORACLE?

I have this query that needs to be executed for oracle sql instead of mysql which is where it originally came from, but I have the ADDDATE() function which I don't see any other alternative than DateAdd since it needs more parameters than I really need..
Apart from that, if I try to execute it, it also indicates an error in the
SELECT 0 i UNION.................
part, saying the following ORA-00923: FROM keyword not found where expected
Maybe in oracle it is not allowed to do a select 0 union select 1 union...
Any suggestions or help I appreciate it, thanks
SELECT
ADDDATE('1970-01-01', t4.i * 10000 + t3.i * 1000 + t2.i * 100 + t1.i * 10 + t0.i) selected_date
FROM
(
SELECT 0 i UNION SELECT 1 UNION SELECT 2 UNION SELECT 3 UNION SELECT 4 UNION SELECT 5 UNION SELECT 6 UNION SELECT 7 UNION SELECT 8 UNION SELECT 9
) t0,
(
SELECT 0 i UNION SELECT 1 UNION SELECT 2 UNION SELECT 3 UNION SELECT 4 UNION SELECT 5 UNION SELECT 6 UNION SELECT 7 UNION SELECT 8 UNION SELECT 9
) t1,
(
SELECT 0 i UNION SELECT 1 UNION SELECT 2 UNION SELECT 3 UNION SELECT 4 UNION SELECT 5 UNION SELECT 6 UNION SELECT 7 UNION SELECT 8 UNION SELECT 9
) t2,
(
SELECT 0 i UNION SELECT 1 UNION SELECT 2 UNION SELECT 3 UNION SELECT 4 UNION SELECT 5 UNION SELECT 6 UNION SELECT 7 UNION SELECT 8 UNION SELECT 9
) t3,
(
SELECT 0 i UNION SELECT 1 UNION SELECT 2 UNION SELECT 3 UNION SELECT 4 UNION SELECT 5 UNION SELECT 6 UNION SELECT 7 UNION SELECT 8 UNION SELECT 9
) t4

In Oracle you must select from the one-row table dual in order to select one row. You cannot select without a from clause.
If you want to generate dates, you'll write a standard SQL recursive CTE. (And this is the typical approach now in MySQL, too, since version 8.0.)
Here is an example selecting all days for 1970:
with dates (dt) as
(
select date '1970-01-01' from dual
union all
select dt + interval '1' day from dates where dt < date '1970-12-31'
)
select dt from dates;

Here is another way to SELECT a list of dates for the year 1970. Adjust the starting and ending dates if you want different years or the INTERVAL if you want different periods like seconds, minutes, hours…
ALTER SESSION SET NLS_DATE_FORMAT = 'DD-MON-YYYY HH24:MI:SS';
with dt (dt, interv) as (
select date '1970-01-01', numtodsinterval(1,'DAY') from dual
union all
select dt.dt + interv, interv from dt
where dt.dt + interv <= date '1970-12-31')
select dt from dt;

How to get mean of exams by client with 2 tables?

I know a little bit of sql, only the basic, now I need to create a analytic query but can't do this yet.
I have 2 tables on my db oracle, client and exams:
I am tried a lot of ways to get the mean of exams by client, but no success yet.4
The result expected is:
exams = 13
clients = 6
13/6= 2.166666666...7
How can I do that?

If you have clients who have not taken any exams then you want:
SELECT AVG(COUNT(e.nu_ordem)) AS avg_exames_by_client
FROM cliente c
LEFT OUTER JOIN exames e
ON (c.id = e.id_cliente)
GROUP BY c.id;
or:
SELECT (SELECT COUNT(*) FROM exames) / (SELECT COUNT(*) FROM cliente)
AS avg_exames_by_client
FROM DUAL;
Which, for the sample data:
CREATE TABLE cliente (id PRIMARY KEY) AS
SELECT 1 FROM DUAL UNION ALL
SELECT 2 FROM DUAL UNION ALL
SELECT 3 FROM DUAL UNION ALL
SELECT 4 FROM DUAL UNION ALL
SELECT 5 FROM DUAL UNION ALL
SELECT 6 FROM DUAL;
CREATE TABLE exames (nu_ordem PRIMARY KEY, id_cliente) AS
SELECT 1, 1 FROM DUAL UNION ALL
SELECT 2, 5 FROM DUAL UNION ALL
SELECT 3, 5 FROM DUAL UNION ALL
SELECT 4, 2 FROM DUAL UNION ALL
SELECT 5, 6 FROM DUAL UNION ALL
SELECT 6, 1 FROM DUAL UNION ALL
SELECT 7, 1 FROM DUAL UNION ALL
SELECT 8, 4 FROM DUAL UNION ALL
SELECT 9, 5 FROM DUAL UNION ALL
SELECT 10, 3 FROM DUAL UNION ALL
SELECT 11, 6 FROM DUAL UNION ALL
SELECT 12, 2 FROM DUAL UNION ALL
SELECT 13, 1 FROM DUAL;
Both output:
AVG_EXAMES_BY_CLIENT
2.166666666666666667
If you then add a couple of clients but no more exams:
INSERT INTO cliente (id)
SELECT 7 FROM DUAL UNION ALL
SELECT 8 FROM DUAL
Then the average is:
AVG_EXAMES_BY_CLIENT
1.625
db<>fiddle here

You can try below formula to get the result -
SELECT COUNT(*)/COUNT(DISTINCT id_cliente)
FROM exams;

How to count distinct flags in the sql

BELOW IS SNIPPET OF MY DATA
Here is the sample creation code of testing.
CREATE TABLE MYGROUP ( Category,PERSON,Flag ) AS
SELECT 'Cat1','A','1' FROM DUAL
UNION ALL SELECT 'Cat1','A','0' FROM DUAL
UNION ALL SELECT 'Cat1','A','1' FROM DUAL
UNION ALL SELECT 'Cat1','B','1' FROM DUAL
UNION ALL SELECT 'Cat1','B','0' FROM DUAL
UNION ALL SELECT 'Cat2','A','0' FROM DUAL
UNION ALL SELECT 'Cat2','A','0' FROM DUAL
UNION ALL SELECT 'Cat2','A','0' FROM DUAL
UNION ALL SELECT 'Cat2','B','1' FROM DUAL
UNION ALL SELECT 'Cat2','B','1' FROM DUAL
UNION ALL SELECT 'Cat2','B','0' FROM DUAL
UNION ALL SELECT 'Cat3','X','0' FROM DUAL
UNION ALL SELECT 'Cat3','Y','0' FROM DUAL;
Desired Output:
Category - Count of Distinct Persons with Flag = 1
Cat1 - 2
Cat2 - 1
Cat3 - 0
I need to get my code in Big query to get distinct counts of persons. It shouldnt double count.

You can use conditional aggregation
SELECT
Category,
COUNT(DISTINCT CASE WHEN Flag = 1 THEN PERSON END)
FROM MYGROUP
GROUP BY Category;

The idea is to make a "JOIN" with this result, because an "IN" is quite delay ...

Use dbms_lob versions of instr and subst to deal with CLOB. Note that the second and third argument meaning for dbms_lob.substr() is reversed compared to standard substr(). NOT TESTED!
... select dbms_lob.substr(P_NUM, dbms_lob.instr(',' || P_NUM || ',', ',', 1, level+1)

from dual
connect by dbms_lob.instr(',' || P_NUM || ',', ',', 1, level+1) > 0

Split by passing value as a CLOB & working on the CLOB type variable in regexp_substr.
Then use this in "IN" Clause ...Preferably better than a "JOIN"

Select values is a row as column values

How can I retrieve values in a row as column values?
Example:
Consider the output of below query as INPUT :
Select 1,2,3,4,5,6,7,8,9,10
from dual;
I need a query that can give below output:
COL1
----
1
2
3
4
5
6
7
8
9
10

SELECT 1 AS "COL1" FROM dual
UNION
SELECT 2 FROM dual
UNION
SELECT 3 FROM dual
UNION
SELECT 4 FROM dual
UNION
SELECT 5 FROM dual
UNION
SELECT 6 FROM dual
UNION
SELECT 7 FROM dual
UNION
SELECT 8 FROM dual
UNION
SELECT 9 FROM dual
UNION
SELECT 10 FROM dual ;

If you want to generate a sequence of numbers in Oracle:
with n as (
select level as n
from dual
connect by level <= 10
)
select *
from n;
Or, if you have 10 columns, you can do an unpivot. An easy way is with union all:
select col1 from t union all
select col2 from t union al
. . .
select col10 from t;

Optimize Group by Hour Query - sql

You want to start with something like this: select trunc(d.auditdate, 'HH24') as hh, count(*) from dauditnew d where d.auditdate >= '2017-04-25' and d.auditdate < '2017-04-26' group by trunc(d.auditdate, 'HH24') order by hh; If this misses hours, then you can use a left join with this as a subquery.
