SQL & PL/SQL :: Separate Date Interval By Trimester
Jul 26, 2011
Let's say I have this table:
create table TEST
(
CF VARCHAR2(16),
START_DATE DATE,
END_DATE DATE
)
with
insert into test (CF, START_DATE, END_DATE)
values ('ME', to_date('01-01-2011', 'dd-mm-yyyy'), to_date('31-12-2010', 'dd-mm-yyyy'));
I need make a select where I get n rows, where n is the number of trimesters that compose the date interval in the table. Each of the returned rows must have as start_date/end_date the boundaries of that trimester.(ALL start dates are the first day of a month, and all end dates are the last day of a month)
In this case I need to get:
ME - 01/01/2010 - 31/03/2010
ME - 01/04/2010 - 30/06/2010
ME - 01/07/2010 - 30/09/2010
ME - 01/10/2010 - 31/12/2010
I have a question with Oracle sql developer, i've installed oracle 11g express edition, and i want to insert values 'date' and 'time', but i only got the resultat like this:
Who can tell me how can i do to show just date info in 'date' and same for the 'time'?
Other than the obvious to me, where interval partitioning creates partitions as needed. Is there any performance benefit from using interval partitions vs date range partitions.
One draw back for me is that developers do access the partition name in some of their queries, so if I use date range partitioning this will not break their code. I could not find a way to assign a name to a partition when using intervals, is this always system generated or can this be over-ridden.
I am running Oracle 11.1.0.7 soon to be running on 11.2.0.0
I studied the documentation and many websites about DBMS_JOB but I am still confused.How do I schedule a procedure to run i.e. every sunday 10:00 AM ?This is what I tried:
DECLARE X NUMBER; BEGIN SYS.DBMS_JOB.SUBMIT ( job => X
archive logs to be stored in its own "date formatted" separate folders.I have already configured flashrecovery area and I dont want to change it as backups are stored there.How can I achieve this without changing the flash recovery area location ? db_recovery_file_dest is set to G:log archive dest is set to F
As we know that date datatype can store both date part and time part. If I specify the Date format for my database as 'DD-MM-YYYY HH@$:MI:SS' can i ensure i anyways for a particular columns in the database containing date values the format is 'DD-MM-YYYY' i.e without the time part.Can we specify seperate date formats for specific columsn in database during table creation?
I am studying Oracle® Database VLDB and Partitioning Guide 11g Release 2 (11.2),
ORA-14767: Cannot specify this interval with existing high boundsby giving an example other than given in the above mentioned document.
the example given in the document is as follows:
To increase the interval for date ranges, then you need to ensure that you are at a relevant boundary for the new interval. For example, if the highest interval partition boundary in your daily interval partitioned table transactions is January 30, 2007 and you want to change to a monthly partition interval, then the following statement results in an error:
CREATE TABLE transactions ( id NUMBER , transaction_date DATE , value NUMBER) PARTITION BY RANGE (transaction_date)
I have a problem, we have some datas in a table for example 7500 rows in a table name called table1 upto 11:am today. but after 11:25 am i have only 5500 rows. in that table.
the table can be accessed by many users here. we dont know when the delete happended in that table. is there any query to find the transaction log of this particular table.
the deletion should be happended between 11:00 am to 11:30 am. but we have retrieved the data using timestamp query. but we need to know when the query issued and by which user the query has been issued.
I have created a job using DBMS_SCHEDULER and I want it to run every 30 seconds:
begin dbms_scheduler.create_job(job_name => 'jobu', job_type => 'PLSQL_BLOCK',
[Code]....
My question is how can I take the value 30 from a configuration table? Let's say I have a query like select value from config_table where property = 'job_interval' that returns the number 30. How can I set this value to be the repeat interval for my job?
i have to divide into 3 groups and take a count 7am-12pm, 12pm-7pm, 7pm-7am groups
It looks so complicated to me, because IN time and OUT time together how we do it.
suppose one person 6am IN and out 8PM means he will be in 7am-noon , noon to 7pm, 7pm-7am -- 1, 1 1 on 3 interval another scenario is if one person in 2am in the morning it has to be previous days count. Is this possible to do it in query.
Interval partitioning I keep getting the below error on a table.A more discerning eye is needed
PARTITION DEC_2012 VALUES LESS THAN (TO_DATE('01-01-2013', 'DD-MM-YYYY')), * ERROR at line 26: ORA-14037: partition bound of partition "DEC_2012" is too high
CREATE TABLE STATISTICS_PART ( ID_KEY NUMBER(10) NOT NULL, LUD DATE DEFAULT sysdate, [code]....
I have one page with an interactive report (Page 10) and another with a form to update each entry (Page 20).
The table that these pages refer to have a column called MY_INTERVAL_COL of type INTERVAL DAYS TO SECONDS.
I can successfully display the contents of MY_INTERVAL_COL by extracting DAYS, MINUTES, and SECONDS on Page 10:
TO_CHAR(EXTRACT(DAY FROM MY_INTERVAL_COL)) AS MY_DAYS, TO_CHAR(EXTRACT(HOUR FROM MY_INTERVAL_COL)) AS MY_HOURS, TO_CHAR(EXTRACT(MINUTE FROM MY_INTERVAL_COL)) AS MY_MINUTES,
However, the Automated Row Fetch process appears to ignore columns of type INTERVAL DAYS TO SECONDS on Page 20.
:P20_INTERVAL (database column MY_INTERVAL_COL is used) :P20_DAYS (trying to convert :P20_INTERVAL using TO_CHAR(EXTRACT(DAY... :P20_HOURS (and so on...) :P20_MINUTES
Does Automated Row Fetch ignore columns of type INTERVAL DAYS TO SECONDS?
I'm having trouble using interval data types in a procedure. I need to pass a number of minutes as a parameter, and then use them for arithmetic on a timestamp with time zone. This works no problem:
set serveroutput on create or replace procedure tstz(mins varchar) as begin dbms_output.put_line(systimestamp - interval '10' minute); end; [code]...
I've tried a few variations of data type and type casting for the parameter, but I can't make it work.
I have this remote database A and database B. DB A has 10 views and DB B has 10 tables. I have to pull out data from views of DB A and load into tables of DB B at regular intervals. How do I do this job?
Currently we are inserting the cycle data for all Items every day into above table for all the CCN's.Currently there are 100k Items in our DB and gets inserted every day into above table with Different Rundates for all CCN's.
We need the above data for 6months and we would like to purge the data based on the RunDates.
We thought of creating a Partition on CCN and Interval Subpartition on Run_date with Interval of every 1 day but I could get any materials on the net to have List-Interval partitioning in Oracle 11G.
Also List - Range partitioning doesnt work here as the Dynamic partition used(using Maxused) will contain the data for all Run_dates instead of particular rundate.
I have this requirement to pull the ACTIVE days that a participant holds true in a given month for a specific position he/she holds.The three date ranges here are: LOA dates(leave of absence), XFER dates(TRANSFER in/out of the position),Quality compliance(QUAL start/end dates).So,
INACTIVE DAYS = [(LOA + XFER + WW) - OVERLAPPING DAYS OF (LOA+XFER+QUAL)] CREATE TABLE PAYEES ( RUN_PERIOD DATE NOT NULL, PAYEEID VARCHAR2(20 BYTE) NOT NULL, LOA_START_DATE DATE, LOA_END_DATE DATE, [code]....
I am able to pull out the no of days on a individual basis(count of days for Xfer/LOA/Qual) but I am really not sure as to how should i go about determining the overlapping days between 3 date ranges to determine the ACTIVE/INactive days.
When I connect to a Oracle database(remote) using TOAD client, because of the settings of timeout done at the server end(in Oracle), the TOAD session gets time out in 5 minutes.
I want to know how I can increase the timeout interval or if I can keep on pinging the database server so that the TOAD connection does not gets timeout?
PS: When we connect to a unix server using putty, we can keep on pining the server at regular timeout interval by going to Change Settings->Connection->Set KeepAlive
I Have created a interval partitioned table with local index.But when automatic partitions are created based record insertion, whether local indexes will be created for each newly created partition or not? If created, how to check
Below is the code which I tried
CREATE TABLE interval_date ( date1 date, days VARCHAR2(50) ) PARTITION BY RANGE(date1) INTERVAL (NUMTODSINTERVAL(45,'DAY'))
I am trying to remove duplicates from a table with over 10million records. Below query is working fine but it doesnt contain any COMMIT interval. I have to commit after every 20k or 30k records deletion for which IF loop is necessary.
Query:
delete from customer where rowid in (select rowid from (select rowid, row_number() over (partition by custnbr order by custnbr) dup from customer) where dup > 1);
I am trying to create a partitioned table so that a number (which date converted to number ) partition is created on inserting a new row for release_date column.
note that release_date column is having number data type (as per design) and people want to create an interval based partition on this.
They want data type NOT to be altered.
create table product( prod_id number, prod_code varchar2(3), release_date number) partition by range(release_date) interval(NUMTOYMINTERVAL (1,'MONTH')) (partition p0 values less than (20120101))
11gr2, We need to do partition a existing table of size 20g, But partition key column is NUMBER type and data stored in unix date format.I would like to create a monthly partition table as below. But not able to create.
create table student ( ENTRY_ID number(5,1), NAME varchar2(30 BYTE) ) partition by range ( fun_unix_to_date (ENTRY_ID) ) --> fun_unix_to_date is a customized function to convert unix time stamp to date format.
INTERVAL (100) ( PARTITION CATCH_ALL values LESS THAN (to_date('01-MAR-12','DD-MON-YY')));

I can separate numbers from string (info) and the first value of the string using REGEXP_SUBSTR (see below):
with dat as (select '35263304 Alcatel One Touch 806' info from dual) select info, REGEXP_SUBSTR ( info, '[[:digit:]]+',1 ) tac, REGEXP_SUBSTR ( info, '[[:alpha:]]+',1) brand from dat
But how can I get rest of the values from that string (red color) ?
I just would like to get separately like: 35263304 Alcatel One Touch 806
