PL/SQL :: How To Group By Over A Range
Jun 12, 2012
I have a table like this:
x y AMNT
---------------------------------------
1 120 12
1 120 93
1 125 31
1 260 15
2 56 16
2 115 49
3 45 71
4 19 11
4 16 48
5 94 52
5 98 47
I want to group records on x , y columns and aggregate on amnt column, in which difference between values of y column be less than 10.
The result is like this:
x y sum(AMNT)
------------------------------------------------
1 ? 136
1 260 15
2 56 16
2 115 49
3 45 71
4 ? 59
5 ? 99
What query can I use?

We have a table with timestamp column and having millions of records.We want to create a materialized view or query, which can give count based
-on some group by columns from table and
-group by on condition (if count > 1000) and
-group by on condition (if timestamp range for that group is > 1hr)

formatting the data.I want to group the below table data based on the Grade column for a header_data with start_time and end_time displayed in range. I was trying with group by, partitions etc but no luck. I use version 10gr2.
create table rel_data_mf (header_data varchar2(10),start_time varchar2(100),end_time varchar2(100),grade varchar2(1));
--table rel_data_mf data as comma separated values

I'm trying to group sets of data based on time separations between records and then count how many records are in each group.
In the example below, I want to return the count for each group of data, so Group 1=5, Group 2=5 and Group 3=5
SELECT AREA_ID AS "AREA ID",
LOC_ID AS "LOCATION ID",
TEST_DATE AS "DATE",
TEST_TIME AS "TIME"
FROM MON_TEST_MASTER
WHERE AREA_ID =89
AND LOC_ID ='3015'
AND TEST_DATE ='10/19/1994';
[code]....
Group 1 = 8:00:22 to 8:41:22
Group 2 = 11:35:47 to 11:35:47
Group 3 = 15:13:46 to 15:13:46
Keep in mind the times will always change, and sometime go over the one hour mark, but no group will have more then a one hour separation between records.

I read that rownum is applied after the selection is made and before "order by". So, in order to get the sum of salaries for all employees in all departments with a row number starting from 1, i wrote :
select ROWNUM,department_id,sum(salary) from employees group by department_id
If i remove rownum, it gives the correct output. Why can't rownum be used here ?

Refer to the txt file to create table and insert data.
I executed the following query-
SELECT priority, detail, COUNT(1) FROM TEST GROUP BY priority, detail
and got the following result-
PRIORITYDETAIL COUNT(1)
StandardPatch 27
StandardInitial TSS 1
StandardInitial development 10
StandardProduction deployment5
High PriorPatch 1
Now I want that Initial TSS and Initial development should be combined as Initial together and I should get the result as follows:
PRIORITYDETAIL COUNT(1)
StandardPatch 27
StandardInitial 11
StandardProduction deployment5
High PriorPatch 1

I'm using this code, and it performs fine, but I'm wondering if there is a more elegant way to do it--maybe with "ROLLBACK". Basically (as you can see) I need to get a normal count for each group but also for each group take a percentage of the total count (so all groups pct adds up to 100 (oh yeah, don't test for zero below, but just a test... )
select
c.Event,
c.code,
count(1) as calls,
total.total_count,
count(1) / total.total_count * 100 as pct_of_total
from
table1 c
[Code]....

I have table :TABLE_X and want to select some data locate into specific range of Day/Month. But so far i couldn't find out the way to.
For example, i want to select people born within specific range of date(range : sysdate to (sysdate+7months ahead) Year here should not be consider, only the day and month.
e.g. a range could be from today:Sept,20 to Apr,18.
so what i was trying is to select doing the following.
select TABLE_X_ID, TABLE_X_BIRTH_DATE
from TABLE_X
where to_date(TABLE_X_BIRTH_DATE, 'DD/MM')
between to_date (to_char(SYSDATE, 'DD/MM'), 'DD/MM')
and to_date (to_char(SYSDATE+210, 'DD/MM'), 'DD/MM')
first am not sure if BETWEEN & AND will work for this case, bt it was the most logical way i could think about to get such range.

I am trying to break down the balance_date to display the following groupings:
7:00-17:30 CDT
18:00-4:30 CDT
I currently have the query setup to display by day instead of these time ranges. I would like the output to read
19 May Day
19 May Night
20 May Day
20 May Night
I am fairly new to this, but how would I go about making this change?
SELECT
TO_CHAR(TRUNC(balance_date,'D') + 4,'YYYY') || '-' ||
TO_CHAR(TRUNC(balance_date,'D') + 4,'IW') as year_wk,
TO_CHAR(TRUNC(balance_date,'D') + 4,'IW')as wk,

I am trying to create a SQL query which will check that various postcode formats are valid, but I am having trouble getting oracle sql to check for values within ranges - for example the following returns no rows, even though most of the postcodes I am dealing with start with 'P'.
select postcode from mytable.addresses
where postcode like '[N-R]%'
;
Am I getting my syntax wrong somewhere?

I have a cost data for effective date range as below.

I3 3770 265 2/3/2013 3/31/2013
I3 3770 269 4/1/2013 5/4/2013
This data needs to be represented in a SQL report as below. The Date Range in the below i.e., Starts with FEB, by checking against the sysdate.. That is from sysdate it will display the Quarter data for 4 months as below.
MODEL NOFEB FY13MAR FY13APR FY13MAY FY13
I3 3770 265 265 269 269
Currently I am using a procedural logic to populate data into a different table in the above format. Is there any method to do with a single SQL using PIVOT. Below given is the table structure and Insert scripts.
CREATE TABLE ITEM_TAG(MODEL_NO VARCHAR2(50), TIER_COST NUMBER(13,4), EFFECTIVE_START_DATE DATE, EFFECTIVE_END_DATE DATE );
Insert statements
Insert into ADMIN_COSTPL_OWNER.ECAPS_ENTITLEMENT
(MODEL_NO, TIER_COST, EFFECTIVE_START_DATE, EFFECTIVE_END_DATE)
Values
('I3 3770', 265, TO_DATE('02/03/2013 00:00:00', 'MM/DD/YYYY HH24:MI:SS'), TO_DATE('03/31/2013 00:00:00', 'MM/DD/YYYY HH24:MI:SS'));
Insert into ADMIN_COSTPL_OWNER.ECAPS_ENTITLEMENT
(MODEL_NO, TIER_COST, EFFECTIVE_START_DATE, EFFECTIVE_END_DATE)

I have a table and want to calculate the stdev of a parameter over a rolling window (past 250 records, sorted by ID):
...
stddev(parameter) over (order by ID range between 250 preceding and current row) as SD
...
I don't get any error, but if I calculate the same in excel (=STDEV(250 row range)), it seems that this code does not the same. Is there something wrong with the 250 row rolling window?

insert into asd VALUES(to_date('01-04-2012 08:00','dd-mm-yyyy hh24:mi'),to_date('01-04-2012 10:00','dd-mm-yyyy hh24:mi'));

now in the second insertion I want to alert the entry user that 9am already falls in the saved record which is 8am to 10am and so that this record can't be saved.

I have a table partitioned by Range and subparitioned by hash.
i am issuing the following query .Bcos of security purposes i cannot post the full query.
Select <most of the columns>
FROM qosTesthr PARTITION(PARTITION_ON_2011_11_17)
WHERE starttime BETWEEN to_date('1111170000', 'yymmddHH24mi') AND to_date('1111172359', 'yymmddHH24mi')
Explain plan is
---------------------------------------------------------------------------------------------------------------------------------------------
| Id | Operation | Name | Rows | Bytes | Cost (%CPU)| Time | Pstart| Pstop | TQ |IN-OUT| PQ Distrib
---------------------------------------------------------------------------------------------------------------------------------------------
| 0 | SELECT STATEMENT | | 826K| 171M| 2330 (4)| 00:00:28 | | | | | |
|* 1 | PX COORDINATOR | | | | | | | | | | |
| 2 | PX SEND QC (RANDOM) | :TQ10000 | 826K| 171M| 2330 (4)| 00:00:28 | | | Q1,00 | P->S | QC (RAND)
[code]...
When i use INDEX_SS hint in the query then only the partition scan is happening.
---------------------------------------------------------------------------------------------------------------------------------
| Id | Operation | Name | Rows | Bytes | Cost (%CPU)| Time | Pstart| Pstop |
---------------------------------------------------------------------------------------------------------------------------------
| 0 | SELECT STATEMENT | | 826K| 171M| 810K (1)| 02:42:06 | | |
|* 1 | FILTER | | | | | | | |
[code]...
Performance while using the index is very very slow.Is there any way without using the index and just the partition full scan can be forced by using some hint..

I need to pick a value based on range like if the range is as below
[code]
if value =2000 then its 2000
elsif value >=2001 and value <=2499 it should be 2000
elsif value =2500 then 2500
elsif value >=2501 and value <=2999 it should be 2500
elsif value = 3000 then it should be 3000
[code]
Like this i need to pick a value by hardcoding this range and this look cumbersome in my program , is there a simple way to substitute this entire thing by passing one single value and getting one single value using a command or builtin.
