PL/SQL :: Generate Hours Range
Oct 4, 2012
I have a table with a date field. This field storage dates with hours like this:
01-08-2012 8:30:00
01-08-2012 8:15:00
01-08-2012 9:30:00
01-08-2012 9:40:00
02-08-2012 8:30:00
02-08-2012 9:30:00
02-08-2012 9:34:00
...
I have to generate a report with the day and the frequency :
__Day_______ Hour Range__CountRecords
WEDNESDAY 8 - 9 2
WEDNESDAY 9 - 10 2
THURSDAY 8 - 9 3
The block of the hour must be 1 hour (8-9,9-10 and so on)
how generate the hours range.
My database oracle version is 8i. (I know that is very old but I can't change because It´s a legacy system).

write the query for the following requirement.I need to generate the records for the range (Difference between From_val & to_val) ) for each ID
create table test_base(id varchar2(20) , from_val number , to_val number);
insert all
into test_base values ('A', 6,10)
into test_base values ('B', 22,30)
into test_base values ('C', 123,130)
into test_base values ('D', 852,860)
into test_base values ('E', 30 ,30)
select * from dual ;
[code]....
No need to generate any thing for E as the difference is equal to Zero

I am using PL/SQL Developer.I have two tables: A and BTable A contains serial_from and serial_to values.This is used to define the serial numbers issued to customers (i.e. the start and end range of serial numbers issued).Shown here for a client:
Table B contains the individual numbers, B.serial (within the serial_from and serial_to range) along with other data, and is only created when the serial is used by the client.
I would like to create a list of records for individual clients containing serial numbers issued but not used. i.e. they are in between the serial_from and serial_to values in Table A, but not in Table B.
How can I create a list of numbers issued, but not yet used? Because Table A contains only two values (to and from) no record exists for them, so how do I generate a list and check against it?

I have following requirement. Let say i have to generate a range based on "start number" and "end number" dynamically.Some kind of hash buckets.
e.g Start Number : 1 and End Number : 1001.
Also i want to divide that range based on some dynamic value like for above example 10 ranges of 100 each. and both 1 and 1001 should be included only once and the next row start number cannot be same as previous row end number.
Means
Range 1 1 -101
Range 2 102-200
Range 3 201-300
...
Range 10 901-1001
Is there any way of doing it automatically. I tried with Model clause. it works fine for even cases but for odd i have issues also when i take small start and end number i get an error.
SELECT case when ranges=1 then ranges else ranges+1 end Start_Id, ranges+round((1001-1)/10) End_Id
from
(
[Code].....
I want this to be generic for any values here 1 is Start Number 1001 is end number and 10 is the bucket. I need these parameters dynamic and want's the same kind of results for any values.

I want to write a function that gets:
1. event_date (dd/mm/yyyy)
2. event_start_time (??/??/???? HH24:MI)
3. event_end_time (??/??/???? HH24:MI)
I got a table called EVENTS that got 2 fields:
1. event_date (dd/mm/yyyy HH24:MI)
2. event_end_date (??/??/???? HH24:MI)
and want to check if there is an event in my EVENTS table that occurs in the same dd/mm/yyyy as the input, and can disturb the input event times. means:
input.event_start_time is between EVENTS.event_date
and EVENTS.event_end_date
and
input.event_end_time is between EVENTS.event_date
and EVENTS.event_end_date
but to compare only the hours here! (HH24:MI)
because the date (dd/mm/yyyy) is checked before..
I don't know how to cut only the hours out of the date and compare them, and don't know how to write the whole function.

i am using one query but not getting correct minutes.
here is my query:
v_Interval:= to_timestamp(v_temphrs,'HH24:MI:SS')-to_timestamp(v_outpunch1,'HH24:MI:SS');
v_TotalHrsMin1 := extract(hour from v_interval) * 60 + extract(minute from v_interval);
here v_interval datatype is "interval day to second" and v_temphrs datatype is varchar2 and value is : 12:00:00 and v_outpunch1 datatype is varchar2 and value is: 06:10:00
and v_totalHrsMin1 datatype is number.
here i should get value 370.

format of dtActivityStartDate/dtActivityFinishDate: 2010-09-17 14:50:51.150 Note: Both dtActivityStartDate/dtActivityFinishDate
vcActivityName = Process Request
usdFuncTimeCalc (vcActivityName,dtActivityStartDate, dtActivityFinishDate)
i need to calculate time elasped for that type of activity following are the rules:
(If Process Request is the activity)
Working Days: Monday through Saturday
Hours of Operation: 9AM 5PM
only working hours of day need to the counted like for example if it is sep 15 11 Am is dtActivityStartDate & Sep 17 is dtActivityFinishDate is 10 Am. then time elapsed is 11am to 5pm on sep 15 , 9 to 5 on sep 16 & 9 to 10 on sep 17 so total should be
6+ 8 + 1 = 15 hours + minutes.
format of date time: 2010-09-17 14:50:51.150
vcActivityName = Process Request
Don't worry about process request..

But what I'm looking for is a way to also include all possible hours with the dates, so my output would be like -
01/01/2013 0001/01/2013 0101/01/2013 0201/01/2013 03...31/01/2013 2131/01/2013 2231/01/2013 23

Check the following

Session altered.
SQL> SELECT SysTimeStamp

SYSTIMESTAMP

My doubt is that why Extract(HOURFROMCURRENT_TIMESTAMP) is showing 11 rather than 10?

I am using Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 - Production
I have 2 schemas in my application.
1. Application schema
2. EOD(End of day) schema.
End of day schema is populated from Application schema whenever user runs EOD process. The tables are pulled like this.
1. Master tables : Always deleted and reinserted at each EOD process
2. Log tables for each transaction table: Delta between the last EOD and current EOD data is pulled and are used for populating transaction tables
3. Transaction tables: These are populated from log tables pulled from previous step. The logic is like this
Now based on these tables about 30 reports are generated in EOD schema. Please note that each transaction table will have a EOD_ID and any report generated uses the where condition <transaction table>.EOD_ID = <current EOD_ID>
My log table contract_log and transaction table is contract in EOD schema.
contract_log table has data like this
contract_number contract_date customer_idqtyrateeffective_date
11/Jan/2010CUST-0110101/Jan/2010
1NULLNULLNULL112/Jan/2010
EOD on 1st Jan 2010 constructs contract table as
contract_numbercontract_datecustomer_idqtyrateeod_id
11/Jan/2010CUST-011010EOD-1
(Since the change of rate 11 is not visible on 1st Jan 2010 because it is effective on 2nd Jan 2010)
EOD on 2nd Jan 2010 constructs contract table as
contract_numbercontract_datecustomer_idqtyrateeod_id
11/Jan/2010CUST-011011EOD-2
(Since the change of rate 11 is visible on 2nd Jan 2010)
This logic is working fine. But we run more than 20-30 EODs the processing time increased to 10-15 hours.
It took some time to figure out the issue as a single query when run from toad or pl sql developer runs in few seconds but as a part of the whole package it takes 2-3 hours(each query).
The problem found was that oracle execution plan gets corrupted when the process starts. So what we did was to analyze the tables
after they are pulled. This perfectly solved our problem. Currently the whole process is taking only about 12-13 minutes where about 3 minutes is lost on analyze tables and indexes. I know this is a temporary solution as I need to get out of online analyze of tables and indexes.
My code for table and index regeneration is as below
PROCEDURE sp_gather_table_index_stats(pc_table_name VARCHAR2) IS
CURSOR cur_ind IS
SELECT index_name
FROM user_indexes
WHERE table_name = pc_table_name;
BEGIN
EXECUTE IMMEDIATE ' begin DBMS_STATS.gather_table_stats(user,' || '''' ||
pc_table_name || '''' || '); end;';
FOR cur_ind_rows IN cur_ind LOOP
EXECUTE IMMEDIATE ' begin DBMS_STATS.gather_index_stats(user,' || '''' ||
cur_ind_rows.index_name || '''' || '); end;';
END LOOP;
END;

I currently have a problem where I have two date fields with time stamps. The only bit i am currently interested in in these fields is the time factor. When i display them in their field they have a format of HH24:MI .
I have a start time and end time as well as a duration and duration type. What I am trying to do is the following: when the user inputs the start time, along with the duration say 1 for example and the duration type of say HRS for example I would like to have the end_datetime default to 1 HR from the current start time. This is the code I use on a when validate item trigger to acheive this:
case :blk.duration_type
when 'HRS' then
:blk.end_datetime := :blk.start_datetime + ((1/24)* :blk.duration);
when 'MINS' then
:blk.end_datetime := :blk.start_datetime + ((1/24/60)* :blk.duration);
However, every time it triggers the value put into end_datetime is 0:00 is it something to do with the datatypes im using .

I want to find the hours and minutes between two char field data type.Example I have two char columns one is "start_time" and another one is "end_time".The start time and end time is the machine reading of CNC MACHINE in manufacturing.I want to develope the package to capture the actual machine running time.But I have the start and end time reading in character field.The machine reading format is hour:minutes:seconds only.It will looks like 1234:45:23(the machine ran 1234 hours and 45 minutes and 23 seconds).See the below table to understand my requirements.
start_time end_time result in hours & minutes
---------- -------- -------------------------
345 347 2 hrs
347 350 3 hrs
350 357.20 7 hrs and 20 minutes
If I subtract end_time - start_time I will get the result in char type only not in hours and minutes format.Another example
start_time end_time result in hours & minutes
---------- -------- -------------------------
357.21 360.40 3.19(If subtract end_time - start_time)
