PL/SQL :: Create Script That Makes Added Year Worth Of Partitions Less Manual?
May 23, 2013
mucking on an Oracle 11.2 database, simple range partitioning issue. Seems using a "complex" formula inside the AT clause annoys it? Or am I doing something wrong?
I create the table with RANGE partition just fine:
CREATE TABLE my_part_tab
( id number,
sdate date
)
PARTITION BY RANGE ( sdate )
( PARTITION P2013Q1 VALUES LESS THAN ( TO_DATE('01-jan-2013','dd-mon-yyyy') ),
PARTITION P2013Q2 VALUES LESS THAN ( TO_DATE('01-jul-2013','dd-mon-yyyy') ),
PARTITION P2013Q3 VALUES LESS THAN ( TO_DATE('01-oct-2013','dd-mon-yyyy') ),
[code]...
Table created.(and yes, I'm aware of INTERVAL option that'll do this next part "automagically", however, INTERVAL and REFERENCE partitioning are incompatible, and the child table is using REFERENCE partition). to make things easier on DBA for future, I'm trying to create a script that makes added a year's worth of partitions less manual.So far, I have the following working:
ACCEPT lYear PROMPT "Add Paritions for which calendar year?"
ALTER TABLE my_part_tab SPLIT PARTITION PMAX
AT ( TO_DATE('01-apr-&lYear','dd-mon-yyyy') ) INTO ( PARTITION P&lYear.Q1,PARTITION PMAX );
ALTER TABLE my_part_tab SPLIT PARTITION PMAX
AT ( TO_DATE('01-jul-&lYear','dd-mon-yyyy') ) INTO ( PARTITION P&lYear.Q2,PARTITION PMAX );
[code]...
But no luck ...Same issue with other variations:
ALTER TABLE my_part_tab SPLIT PARTITION PMAX
AT ( (ADD_MONTHS(TO_DATE('01-jan-&lYear','dd-mon-yyyy'),12)) ) INTO ( PARTITION P&lYear.Q4,PARTITION PMAX );
ALTER TABLE my_part_tab SPLIT PARTITION PMAX
AT ( (TO_DATE('01-jan-'||TO_CHAR(TO_NUMBER('&lYear')+1,'fm9999'),'dd-mon-yyyy')) ) INTO ( PARTITION P&lYear.Q4,PARTITION PMAX );
I am writing a query where I'd like to pull one year's worth of data. Ideally I want to prompt for the END DATE and have the query go back in time one year from that date.
Here is what I've got after doing some research online... but It's not quite working for me.

My developer came with a requirement of creating partitions on a table which has 40 million records. His exact requirement is to create as many as partitions in such a way that 1 partition should not exceed 5k-10k records and these records should be inserted/updated on the same date (i.e. using a column as source_timestamp field). How to accomplish this?
partition 1 = < 2011 partition2 = <2012 partition 3 = any other value not staisfying partition 1 and partition 2
i would like to know how to create a partition 3 without specifying the range so that the data which are not coming under the range of other partitions (Partition 1 & 2) will automatically goes to this partition 3.
Also in the above case if i insert data of year 2009 then where will it go , to partition 1 (or) 2 since both of them matches the condition (<2011 and <2012) (or) do i need to use between clause while creating partitions?
insert into sample values('1','01-JAN-2005'); insert into sample values('1','1-JAN-2006'); insert into sample values('2','2-JAN-2007'); insert into sample values('3','4-JAN-2005'); insert into sample values('4','11-JAN-2004'); insert into sample values('3','2-JAN-2005'); insert into sample values('2','12-JAN-2006'); insert into sample values('1','21-JAN-2005'); insert into sample values('2','11-JAN-2005'); insert into sample values('7','01-JAN-2005'); [code]....
, I'd like to create a constraint (when creating a table) that checks to ensure that the 'Year' entered is less than or equal to the current year (based off SYSDATE). Per the code below, I keep getting the same error, "missing right parenthesis". I've spent more than an hour trying different ways to get this to work, but I've been failing miserably. I am using Oracle 11g Express.
CREATE TABLE TEST (Name VARCHAR2(7) PRIMARY KEY, Year NUMBER(4), CONSTRAINT TEST_YEAR_CK CHECK (Year <= (TO_NUMBER(TO_CHAR(SYSDATE, 'YYYY')))FROM DUAL); *ERROR at line 4:ORA-00907: missing right parenthesis
Using Oracle 11g...We have a table in our database of data with the following information:
MASTER_RECORD, MEMBER_RECORD, BUSINESS_UNIT, GENDER, DOB (date), age [at time of month_record], MONTH_RECORD (date) [31-MON-YEAR for recorded active month]
The table has ~55 million records. Existing index is only on MASTER_RECORD.There is now a need to create a view which is an aggregate count of member records, grouped by business_unit,gender, age per year. eg:
business_unit, gender, age, month_record, num_of_members -> for every combination unit5, F, 25, 31-JUN-2011, 622 unit3, M, 18, 31-MAY-2011, 573
The view can be created now, but, is not fast enough to be reasonably considered a view. This table is re-created every month from a procedure, so there is flexibility on how it is created. Use interval partitioning by year( something I have not experienced using), create an index on the month_record,then create view.
I have a query with a few tables in join, and I filter data with something like
where mytable.initial_date > sysdate-30
If I use any date, it takes about 5 seconds to run, but if I use
to_date('01010001','ddmmrrrr')
instead of any other dates, it takes just a few milliseconds. Now, it's just a curiosity, but why that date makes the query VERY fast? Does Oracle treat it in some special way? Maybe it knows every date is greatest than that date and doesn't consider the filter?
I am using 10g and want to let an user to delete a single record from a multirow form via delete button. This button is supposed to do the same, what the "delete record" button on the default menu does. (I want a custom menu, so I can't use that button)
My delete button ist assigned to a control-block and the when-button-pressed-Trigger of that button looks like this: ------------- DECLARE TEMP VARCHAR(30); BEGIN -- Record chosen? IF :<BLOCK>.ID IS NOT NULL THEN
[Code]...
The problem is, that the alert asks the user about the previously chosen record correctly, but if the user clicks BUTTON1 the Form says: No changes to save (FRM-40401).
I recently needed a select list that would allow you to choose from a years worth on Mondays starting with the current week's Monday. It will return the date of that Monday. I thought others might be able to use this too... Plus I wanted to be able to find this in the future.
SELECT DISTINCT to_char(trunc(next_day(trunc(SYSDATE,'day'),2)-1+LEVEL,'iw'),'FMMonth DD, YYYY') AS Display ,trunc(next_day(trunc(SYSDATE,'day'),2)-1+LEVEL,'iw') as Return FROM dual CONNECT BY LEVEL <=((add_months(trunc(SYSDATE,'day'),12)-1)-(trunc(SYSDATE,'day'))) ORDER BY 2;
As of today (Friday, August 24th) the above would return:
DISPLAY RETURN August 20, 2012 20-AUG-12 August 27, 2012 27-AUG-12 September 3, 2012 03-SEP-12 September 10, 2012 10-SEP-12 September 17, 2012 17-SEP-12
i want a select statement to retrieve the last name added into the "ename" column .i mean :if i insert "jack" into "ename" column , i want to write a select statement to retrieve that last name while i do not know it is jack or any other name ?

After compiling a simple valid SP in Toad for Oracle 8.5.1:
CREATE OR REPLACE PROCEDURE proc_test AS DECLARE v_name VARCHAR2(20) := 'Ed Edson'; BEGIN DBMS_OUTPUT.PUT_LINE('Hi, my name is ' || v_name); END;
The SP is not added to the schema. Also the three status fields (status, created and Last Update in the Procedure Editor remain <Unknown>. It is not a rights or privilege issue, because the creation works perfectly in SQL*Plus!
If one of the redolog member corrupted and overcome this problem, I had removed the corrupted redolog member. Later I had added a new member to this group.
I would like to know, is the newly added log member will get sync with existing log member? How the newly added log member get sync with existing log member?
Mistakenly I added lot of datafiles with autextend on option.. I realized later and then tried to resize the datafiles to a minumum space but got the below error

How to resolve this problem to reclain the space back?
One of my Customer had followed the document applied pertaining to mitigate against vulnerability CVE-2012-3132.
New Document Mitigation steps for CVE-2012-3132 [ID 1482694.1]
This was applied to a database and it stopped the 'password' command from succeeding in SQLPLUS. Once the trigger was disabled, it worked fine.
ORA-00604: error occurred at recursive SQL level 1 ORA-06531: Reference to uninitialized collection ORA-06512: at "SYS.NAME_SECURITY", line 165 ORA-06512: at line 2
Why is this behavior seen? By the way, he was able to change the password using TOAD. Only sqlplus is the issue.
i recently installed an apex plugin but after deinstalling the plugin some of the functionality was still there.I suspected the plugin uploaded a js library and a css file.I found the functions apex_javascript.add_library and apex_css.add in the plugin.Where does apex save the files that are uploaded using those functions?I want do remove then.

I am facing some challenge while running update query on newly added column in existing table.
Environment Details Oracle 9i, version 9.2.0.6 Os Unix Aix 6.1
No of records in table : 12572770
Below are the step i followed.
1. In table testtablename, I have added new column COLUMNNAME29 with datatype VARCHAR2(8). 2. After adding the new column, i executed the update query to populate the data form COLUMNNAME1 to COLUMNNAME29. 3. The query is executed using COLUMNNAME24 in where clause, to drive query in index based.
SQL> desc testtablename Name Null? Type ----------------------------------------- -------- ---------------------------- COLUMNNAME1 VARCHAR2(8) COLUMNNAME2 CHAR(1) COLUMNNAME3 CHAR(1) COLUMNNAME4 VARCHAR2(8) COLUMNNAME5 VARCHAR2(11)
[Code]...
Table altered.
SQL> select index_name, column_position, column_name from dba_ind_columns where table_name = 'TESTTABLENAME' order by index_name,column_position;
1. The update query is hanging in database, it's not progressing (In single update, approximately 40000 records will get update) 2. No oracle error thrown in alert log or in session where the query being executed. 3. The event for the query is "db file sequential read". 4. When i update the newly added column COLUMNNAME29 with static value "1", the update completed successfully in few seconds. 5. Then i changed the static value to "1111" and executed the update statement, which result to query hanging in database. 6. I tried to update the existing column(COLUMNNAME1) in table with static value "1111", the update completed successfully.
Below are the queries completed successfully
Update Testtablename Set Columnname29 = '1' Where Columnname24 >= To_Date('01-12-2002 00:00:00', 'DD-MM-YYYY HH24:MI:SS' ) And Columnname24 < To_Date('01-01-2003 00:00:00', 'DD-MM-YYYY HH24:MI:SS')

Phyical memory : 420G My database version : 11.2.0.3 running on linux machine.
Memory_target = 200G . I would like to allocate this value to following SGA components. I don't want to automatic memory management enabled. how to split 200G for following components. Is there any percentage for each components ?
The DB was created but when i log in again, it is looking for the pfile in the another DB's location rather than from "%ORACLE_HOME%DATABASE". Where i missed out to create new oracle_home folder?
I am running some small tests here in my test env, using dataguard. I have configured the Primary and Standby with Maximum Availability... they're running just fine. Now i want to execute a failover test (i have already ran a Switchover test with the Broker successfully).
My question is very simple, at my point of view: What are the required steps to execute a successful manual failover? For example, i have my env as follows:
- Primary: prim1 - Standby: stdb1
Suppose that the primary database crashes in an unrecoverable way... is this case a manual failover would be necessary.
To do so, i would have to execute the following command, in my Standby database:
-- stdb1 is the standby database... DGMGRL> failover to stdb1
The above command is correct? Are there any required configurations after the failover? I read the Oracle Docs, and it says
Those SQL reports are built with apex_items. Afterwards I'm updating them with a manual process (apex_application.g_fxx for ..loop). I'm using different IDs on both reports for the apex_items.
It's working fine for the first report displayed. But not for the second one. If I swap the two reports, it's always the first that will be updated.
Does it mean that we cannot use the apex_application to update more than one report and that I have to use a page per report?
