PL/SQL :: Delete Scott And Storage Information Same Time Using REGEXP_REPLACE?
Jul 11, 2013
I used REGEXP_REPLACE to delete Scott. is there any way to delete Scott and Storage information same time using REGEXP_REPLACE...?
select REGEXP_REPLACE(dbms_metadata.get_ddl('TABLE','EMP'),'("Scott".)','', 1, 0, 'i') from dual; result: CREATE TABLE "EMP" ( "EMPNO" NUMBER(4,0) NOT NULL ENABLE, "ENAME" VARCHAR2(10), "JOB" VARCHAR2(9), "MGR" NUMBER(4,0), "SAL" NUMBER(7,2), "DEPTNO" NUMBER(2,0)) PCTFREE 10 PCTUSED 40 INITRANS 1 MAXTRANS 255 NOCOMPRESS LOGGINGTABLESPACE "USERS"I want:CREATE TABLE "EMP" ( "EMPNO" NUMBER(4,0) NOT NULL ENABLE, "ENAME" VARCHAR2(10), "JOB" VARCHAR2(9), "MGR" NUMBER(4,0), "SAL" NUMBER(7,2), "DEPTNO" NUMBER(2,0))

Sequence nextval is a pseodocolumn, but where the value of nextval is stored and why before we use CURRVAL for a sequence in our session, we must first initialize the sequence with NEXTVAL?

After a power failure, I have now dropped disks in my 2 diskgroups DG_RACDATA1 and OCRVD.
Disks has been renamed and prefixed by DROPPED...
Their state is now "FORCING"
Mount status = missing
header status = unknown
Mode status = Offline
These disks was belonging to a failure group with redundancy so the cluster still works ...but I have lost the redundancy.
How to reuse these offline disk or confirm that what I plan to do is good:
Shall I put them online ? ALTER DISKGROUP DG_RACDATA1 ONLINE DISK DROPPED0000_DG_RACDATA1
Shall I drop them ? ALTER DISKGROUP DG_RACDATA1 DROP DISK DROPPED0000_DG_RACDATA1 FORCE
and then: zeroing them and readd to failgroup ? but how ?

I want to delete the records which are less than or equal to this date
MIN(TRUNC(sale_week_date)-(1/(24*60*60)))
For that I have created the following procedure.
CREATE OR REPLACE PROCEDURE DELETE_DATA_WEEKISMIN_DATE DATE;SELECT MIN(TRUNC(sale_week_date)-(1/(24*60*60))) INTO MIN_DATE
FROM sales_week; DBMS_OUTPUT.PUT_LINE(MIN_DATE);
DELETE FROM sales WHERE sale_date <= MIN_DATEAND sales_creation_date <= MIN_DATEAND sales_update_date <= MIN_DATE; END;
If declare as MIN_DATE Date;
it's not taking time. If declare as MIN_DATE Timestamp; It is taking milli seconds also. 18-OCT-13 11.59.59.000000 PM SALE_DATE ,SALES_CREATION_DATE and SALES_UPDATE_DATE in this format 18-OCT-2013 11.59.59 AM. How to delete the records which are less than or equal to this date MIN(TRUNC(sale_week_date)-(1/(24*60*60))) ..

I have a table which contains 8,21,177 amount of data totally.Now I am trying to delete around 4,84,000 of data from this table by using just one filter i.e. my query is something like below
DELETE /*+ parallel(resource,4) */ FROM resource where created_by = 'MIGN'
This is going to delete 4,84,000 rows of data . But my current issue is this is taking lots of time to delete the data . To be precise , its almost taking 25 hours to delete this data..The created_by column is indexed .

I've been tasked to parse tags from a string that look like the following:
{Date + XXX}
where XXX represents a numeric value. I have to replace this, including the brace characters with
SYSDATE + XXX
which will ultimately calculate SYSDATE plus the number of days suggested by XXX. The problem is that I am trying to use regexp_replace to achieve this goal but since XXX is completely arbitrary, I cannot search for it as a fixed value. So, ultimately, I would like to use a regular expression that ignores the numeric part of my search and only replaces the starting brace, the "Date + " part and the ending brace, leaving the numeric portion intact. I was trying to do something like the following
myString := regexp_replace(myString, '{(Date + [^[::digit:]]{1,})}', to_char(SYSDATE, 'FMMONTH DD, YYYY'));
in hopes of making it ignore the numeric part but it, instead, treats occurrences as a non match. Alternatively, the call below
myString := regexp_replace(myString, '{(Date + [[:digit:]{1,})}', to_char(SYSDATE, 'FMMONTH DD, YYYY'));
matches correctly but replaces the numeric portion as well, so I'm left with just today's date instead of the calculated future date...

I am looking for the best fastest to process by searching string and replace values. I am process many rows like 200k,
search for strings starting with "S" or "M" and replace only those letters with NULL eg S8795371 becomes 8795371, and M4454332 becomes 4454332 however other string values shouldn't be affected only if it starts with S/M. i was thinking of using REGEXP_REPLACE and what is the best way to construct this statement?

In my code I am using delete statement which is taking too much time to execute.
Statement is as follow:
DELETE FROM TRADE_ORDER_EMP_ALLOCATION T
WHERE (ARTEMIS_SOURCE_SYSTEM_ID,NM_ARTEMIS_SOURCE_SYSTEM,CD_BOOK_KEY,ACTIVITY_DT)
IN (SELECT ARTEMIS_SOURCE_SYSTEM_ID,NM_ARTEMIS_SOURCE_SYSTEM,CD_BOOK_KEY,ACTIVITY_DT
FROM LOAD_TRADE_ORDER
WHERE IND_IS_BAD_RECORD='N');
Tables Used:
oTRADE_ORDER_EMP_ALLOCATION Row count (329525880)
oLOAD_TRADE_ORDER Row count (29281)
Every column in "IN" clause and select clause is containing index on it
Every time no of rows which to be deleted is vary (May be in hundred ,thousand or hundred thousand )so that I am Unable to use "BITMAP" index on the table "LOAD_TRADE_ORDER" column "IND_IS_BAD_RECORD" though it is containing distinct record in it.
Even table "TRADE_ORDER_EMP_ALLOCATION" is containing "RANGE" PARTITION over it on the column "ARTEMIS_SOURCE_SYSTEM_ID". With this I am enclosing table scripts with Indexes and Partitions over it.
way for fast execution in of above delete statement?

Basically I need to use REGEXP_REPLACE in order to remove from a string certain oracle code pricislly those which are used on RAISE_APPLICATION_ERROR from 20000 to 20999. We have an application here that handles those exceptions and each exception append each other so inside them we can find those ORA-20001: Some error. ]
So I was wondering if I can achieve that by using REGEXP_REPLACE. So which regexp I could use so that I can remove those oracode only!

I'm trying to eliminate duplicate string for more than 1 occurrences along with its delimiters, but couldn't get it working. Here is what I tried.
SQL> column str format a30
SQL> column replaced format a30
SQL> with x as
2 (select 'a#~#b#~#a#~#d' as str from dual union all
3 select 'a#~#b#~#c#~#a' as str from dual union all
4 select 'b#~#a#~#c#~#a' as str from dual)
select str,
regexp_replace(str, '[^a|#~#a]{2,}','',1,2) replaced
from x; 5 6 7
STR REPLACED

My organisation is currently discussing different storage options for the database storage. Our production database is nearly 2TB and we do not want to continue with the existing NetApp storage (we use a 2 node RAC running 11.2.02 with nfs filesystem from NetApp filer).
We were looking at different options and came across Nimble Storage, they are very fast growing company aiming mid-range storage customers. The initial talks and demonstration looked very promising in terms of IO performance (they claim 40,000 - 60,000 IOPs for their CS400 series Nimble Storage array) and other options they are providing but we understand that majority of their customers are using it for VDI and other infrastructures.
They have demonstrated us using if for Oracle database with ASM storage over iSCSI LUNs. We are yet to do the POCs and benchmarking.
Has anyone come across Nimble Storage for running Oracle databases?

I have been implementing a script to change a lot of data in a database production.Because of this the database will be 100% dedicated to the execution of that script, in the sense that nothing else will be running in this period (the application will be stopped).
what can i do to improve performance of that execution? is there any oracle manual online for this type of problem? I do not know if it's possible, but I'm thinking of things like disabling locking mechanism (if possible I could run instead of a process many processes in parallel), disabling index growing (during the process), disabling constraints.

I am developing some automated test packages for my PL/SQL Packaged code. Going forward I can code the test package in conjunction with the code but I have some historic packages that I would like to develop these test packages for.
To save time I would like to employ oracle data dictionary views in order to construct the framework for my test package. This includes using SQL to get a list of procedures / functions within the package in order to create the test procedures (spec and body). I can do this in a basic way using the user_procedure view with something like...
SELECT 'PROCEDURE test_' || LOWER(procedure_name)
|| ' (p_result OUT VARCHAR2 IS BEGIN JTA.ACCOUNT_PROFILE_MAINT.' || procedure_name || ' END '
|| LOWER(procedure_name) || ';'
FROM user_procedures WHERE object_name = 'ACCOUNT_PROFILE_MAINT' AND subprogram_id != 0 ORDER BY subprogram_id;
However, the above only really works (in simplistic form.. without parameters) for procedures within the package. I would also like to be able to determine if the procedure listed is actually a function or procedure (so that I can alter the syntax accordingly to generate a correctly formatted string calling the program unit).
So, initially how do I determine the type of package program unit I have (Proc/Function)? Do I need to go to all_source to get this information or are there other views available I can join to?
Eventually I would like to extend this to be able to automatically include any parameters in the generated calling string.. again, is there any other option apart from all_source to get this information?
