getting hour in groups - oracle - whats is wrong - oracle

whats is wrong with this query.
I need to get all hours of the 24 hours period to count hits per hour.
I want to make a case when 0-24 but I can not do the first work
SELECT
(
CASE WHEN (
CAST(TO_CHAR(dg_user_acess.dt_user_acess, 'HH24') >= '00')
AND
CAST(TO_CHAR(dg_user_acess.dt_user_acess, 'HH24') < '01')
)
THEN ('00:00 as 01:00')
ELSE '0' END
) as hour,
count(*)
FROM dg_user_acess
GROUP by hour
i get the error
Erro de SQL: ORA-00905: palavra-chave não encontrada
00905. 00000 - "missing keyword"
the table data is like this
pk| dt_user_acess
01| 2014-10-21 08:30:12
02| 2014-10-21 08:40:27
03| 2014-10-21 08:56:18
04| 2014-10-21 09:15:19
05| 2014-10-21 10:42:48
...
and the result I would like something like this (not write the case when all schedulesin query to not pollute the code)
'00:00 as 01:00' 0
'01:00 as 02:00' 0
'02:00 as 03:00' 0
'03:00 as 04:00' 0

whats is wrong with this query [?]
You have many (more or less severe) issues with your query -- in no particular order:
The correct syntax for CAST is CAST(value AS type)
You use hour as a column name, but it is a reserved word
You compare strings where it is probably numbers that you should compare
You seems to expect a "dense" result set, but as you don't use a join, there is no chance for the result set to have more rows than the original table (probably less in fact, as you GROUP BY)
Given your needs, you probably missed the EXTRACT(HOUR FROM ...) function. In order to extract all the "hits" for an hour, you would write that:
SELECT
EXTRACT(HOUR FROM dg_user_acess.dt_user_acess) as "hour"
FROM dg_user_acess
As you need to COUNT them (and since you cannot use an alias in a GROUP BY clause) you might use a sub-query. Don't worry too much about that: Oracle is smart enough to optimize that kind of request:
SELECT "hour", count(*) "cnt"
FROM (
SELECT
EXTRACT(HOUR FROM dg_user_acess.dt_user_acess) as "hour"
FROM dg_user_acess
) V
GROUP BY "hour";
Finally, as you need a dense output (i.e.: with all hours in the range 0-23), my option would be to use a join on a generated table:
SELECT "hour", NVL("cnt",0) "cnt"
FROM (
SELECT LEVEL "hour" FROM DUAL
CONNECT BY LEVEL < 24
) CLOCK
LEFT JOIN (
SELECT "hour", count(*) "cnt"
FROM (
SELECT
EXTRACT(HOUR FROM dg_user_acess.dt_user_acess) as "hour"
FROM dg_user_acess
) V
GROUP BY "hour"
) G
USING ("hour")
ORDER BY "hour";
All of this leads to rather complexly nested queries. But this has the benefit of being easy to write incrementally as you just see it. Now that I showed the basic building blocks, perhaps we could do a better job. Maybe that:
SELECT CLOCK."hour", COUNT(dg_user_acess.dt_user_acess) "cnt"
FROM (
SELECT LEVEL "hour" FROM DUAL
CONNECT BY LEVEL < 24
) CLOCK
LEFT JOIN dg_user_acess
ON CLOCK."hour" = EXTRACT(HOUR FROM dg_user_acess.dt_user_acess)
GROUP BY CLOCK."hour"
ORDER BY CLOCK."hour";
Depending your schema and data, this might or might not perform better than the previous version. Feel free to take some time to experiment all these queries on http://sqlfiddle.com/#!4/678a5/17

i get some result changing the group by and the condition of the case (and remove the cast).
I do not know if it's the best way to do this, but it worked

Need Final Output Result in this format:
You haven't said what your expected output is; however, you appear to want to order by the weekly amount so you need to order by the rank_this_week column and not include amount in the GROUP BY clause:
SELECT RANK() OVER (
ORDER BY SUM(
CASE
WHEN datetime >= TRUNC(SYSDATE, 'IW')
AND datetime < TRUNC(SYSDATE, 'IW') + INTERVAL '7' DAY
THEN amount
END
) DESC
) AS rank_this_week,
product_name,
SUM(
CASE
WHEN datetime >= TRUNC(SYSDATE, 'IW')
AND datetime < TRUNC(SYSDATE, 'IW') + INTERVAL '7' DAY
THEN amount
END
) AS total_amount_this_week,
SUM(AMOUNT) TOTAL_AMOUNT
FROM PRODUCT_TABLE
GROUP BY product_name
ORDER BY rank_this_week
FETCH FIRST 10 ROWS ONLY;
Which, for the sample data, outputs:

How to get past three months sales continuously?

I have sales data, I need to filter who(Agent id) is done more sales end of the last 3 days of the month, did more than 80 % sales (last three days sales/ Total sale particular month ), and continuously did the past three months.
I tried the below query it satisfies only the last three days sales more than the rest of the days and more than 80% sales that particular month((last three days sales/ Total sale particular month) . But I couldn't get who is done continuously for three months.
Example: One Agent, he did sales last 3 days sales more compare to the rest day sales and more than 80% sales in the last three days July and continuously did past three months (July, June, May)

Oracle 11g Sql convert date from blob field

I have a problem in converting a date value stored in a blob field in Oracle 11g sql command. When i execute the sql:
select dump(HIGH_VALUE) from all_tab_columns where COLUMN_NAME='TARIH'
i receive the following result;
Typ=23 Len=7: 120,116,3,6,1,1,1
I know that these numbers represent a date (not datetime), but i don't know how to extract the date from this result.
Thanks in advance,
Alper
Oracle stores dates in tables as 7-bytes
byte 1 - century + 100
byte 2 - (year MOD 100 ) + 100
byte 3 - month
byte 4 - day
byte 5 - hour + 1
byte 6 - minute + 1
byte 7 - seconds+ 1
So 120,116,3,6,1,1,1 converts to:
byte 1 - century = 120 - 100 = 20
byte 2 - year = 116 - 100 = 16
byte 3 - month = 3
byte 4 - day = 6
byte 5 - hour = 1 - 1 = 0
byte 6 - minute = 1 - 1 = 0
byte 7 - seconds = 1 - 1 = 0
So 2016-03-06T00:00:00
Oracle Setup:
CREATE TABLE file_upload ( file_blob BLOB );
INSERT INTO file_upload VALUES (
utl_raw.cast_to_raw(

Can somebody tell me why I am getting this error. Is there an efficient way to write this query?
You have TO_NUMBER (SUBSTR (a.os_version, 1, 1) in your queries, so presumably you're hitting data that doesn't have a number at the start of the os_version, when you request more than 100 rows.
You need to check your data.
This error happens when you try to convert a non-numeric value with TO_NUMBER.
In the second query the first 100 rows seem not to result into a.os_version to a non-numeric value.
Try a simple select vw_mobile_devices_all to find the non-numeric os_version. Figure out how you can work around the problem. Maybe you can query the os_version differently.

Oracle performance tuning order by is taking time

Am having query,in which two fields and getting as output pps_id and total_weight. Here pps_id is the column from the table and total_weight we are calculating from inner query. after doing all process in query we are order by the query by total weight. Its taking more cost and response.Is there any way to improve this query performance.
SELECT PPS_ID, TOTAL_WEIGHT
FROM ( SELECT PPS_ID, TOTAL_WEIGHT

i have tried by splitting the query and put values in temp tables and tried but it also taking time. I want to improve the performance of the query
