SQL & PL/SQL :: Remove Only One Leading 0?
Jun 3, 2010
I receive source data with leading zeros. The Rules says: "If there is a leading 0 it has to be removed and data has to be shown starting with character 2".Here is my code I started with:
CREATE TABLE leading_0_test
(
col_1 VARCHAR2(10)
)
insert into leading_0_test values('00123')
select trim(leading'0' from COL_1),trim(leading'0' from substr(COL_1,1,1)),COL_1 from leading_0_test
The first trim removes all leading zeros. Therefore I tried to solve it with the substr, but without success.

So many of the queries in our database query by an account but an account is allowed to vary by prefix and so queries are written similar to account like '%suffix'
Our DBA has rejected the use of context indexes and friends to deal with this.
as an aside and I'm probably going to regret going into this much detail but our model is
A->>B->>C
typically the queries want to fetch C's for a customer defined by A.account
A, B, C are all partitioned with partition key created_date
however, only C is typically queried with created_date as a qualifier. A and B are related by joins from A->>B and B->>C
when queries are written to use '%' leading wildcards often it results in a full table scan across multiple partitions. on any given day all we care about are the most recent C's for the customer where customer is defined by A.account.
I recently had an idea whereby fields such as A.Account could also be kept(denormalized) in the C table
the idea is if the queries were written to use C.account like '%bla' instead of A.account like '%bla' then because C is always qualified with the partition key ie. C.created_date that would at worst result in a full partition scan only. this is considerably less expensive than doing a full table scan of A. The IO cost of doing that is huge.
populating the C.account is a simple before insert or update trigger. when you insert a C you have a foreign key to a B and B has a foreign key to A. A and B are always created before any C is seen for any given C. When a C is seen A and B already exist in the database.

I am generating an XML file from plsql using utl_file.There is a problem in number field.The value in the table is 0.18 and it is showing up in xml as .18. The leading zero is not showing up.
COLUMN_NAME is number (15);
<TAG>' || A.COLUMN_NAME || '</TAG>
I have tried using to_char(), but it is still showing up as .18 in XML. I want it as 0.18 in XML as well.

We wrote a query to spool the results in TAB delimited flat file, Results are ok but when copied into excel the leading zeroes are getting wiped off.
Example:
Result: 0000123 and when copied into excel the value is just 123. I need to retain the value as it is 0000123.
Can we control it in the query itself rather than correcting the excel.

I ran the CROSSCHECK BACKUP and DELETE OBSOLETE and DELETE EXPIRED BACKUP, and they works.
But how can I remove these lines? Are they still important for anything?

remove duplicates from my collection(table type).Or an alternate solution for my issue is get clean data into my collection which i am not able to get to either.
Object creation
create table testingtype_table(ordernumber number,org_id number , company_name varchar2(10))
insert into testingtype_table values (1124,2424,'cbaaa');
insert into testingtype_table values (1124,2424,'cbaaa');
create or replace type testingtype_obj as object (ordernumber number,org_id number , company_name varchar2(10));
create or replace type testingtype_tab as table of testingtype_obj;
Code Block
declare
l_testingtype_tab testingtype_tab := testingtype_tab();
begin
select distinct testingtype_obj(ordernumber
,org_id
,company_name)
bulk collect into l_testingtype_tab
from testingtype_table;
end;
If only i can get a way to bulk collect only distinct values into the table type that will just do great but when i try the above (with distinct highlighted in red) it throws an error
ORA-22950: cannot ORDER objects without MAP or ORDER method

I do have a query which gives me two rows of data.(This might be more than two in other cases)
The data I get is formed as :
COUNTRY_DESCRIPTION COUNTRY_CODE EVENT_NUMBER EVENT_DATE APPLICANT
European Patent EP 101 Kiksu
European Patent EP 101 Mokilosu
What I want to get should be formed as :
COUNTRY_DESCRIPTION COUNTRY_CODE EVENT_NUMBER EVENT_DATE APPLICANT
European Patent EP 101 Kiksu
Mokilosu
As you can see, I removed the first four columns because the eventkey is the same. In this case, there is only the applicant which is different.So the rest should be blank.
The code I do use to get this data:
SELECT
TABLECOUNTRY.COUNTRYDESCRIPTION "COUNTRY_DESCRIPTION"
,TABLECOUNTRY.COUNTRYCODE "COUNTRY_CODE"
,OWNER.NAME "APPLICANT"
,CASEEVENT.EVENTNUMBER "EVENT_NUMBER"
,TO_CHAR(CASEEVENT.EVENTDATE,'DD.MM.YYYY') "EVENT_DATE"
[code]....
So what to modify in the query to get these columns of the second row blank?

How to write a pl/sql query to trim/remove more than one character from string.
Like the itemfield is 'Profit CY' I want it to show as 'Profit' but only for itemfields that say 'Profit CY' in the column for remaining items in column such as 'Loss CY' should stay as it is.

My query is suppose to capture the student's number, date of birth, and number of students which that students mentors. I am suppose to show only the 5 oldest students
SELECT s.std_num, s.birth_date, COUNT(s2.mentor_num)
From Student s left outer join Student s2
on s2.mentor_num=s.std_num
GROUP BY s.std_num, s.birth_date
ORDER BY s.birth_date ASC;
This function works but the problem is in displaying the five records because whenever I apply the rownum<=5 function the counter returns incorrect results. I tried writing another query to fix it but I could not dispay the counter anymore
SELECT ROWNUM as SENIOR, s.std_num, s.birth_date, COUNT(s2.mentor_num)
FROM (SELECT s1.std_num, s1.birth_date, COUNT
(e2.super_id)
From Student s left outer join Student s2
on s2.mentor_num=s1.std_num
GROUP BY s1.std_num, s1.birth_date
ORDER BY s1.birth_date ASC) S
WHERE row_num<=5;
This code only works if I remove the count in the first line but I need to display the number in my result.

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!

In Oracle XE when I run PL/SQL in the SQL Commands window I will sometimes get a "Not found" error. It further reads, "The requested URL /apex/wwv_ flow.show was not found on this server". I found that if I remove all of the indentations from the lines of the PL/SQL code everything will work fine. Talk about a screwy problem. So, if you have that problem just take all of your PL/SQL code and slam it up against the left margin.

I am using an Oracle view and package to extract data from my DB to build an XML file on the fly.
My problem is that on very rare occasions, an invalid XML character will be in the database. This, of course, causes my XML file to error.
My question is: What are the possible ways to remove invalid XML characters when selecting out of a DB field? Any function that has been written for this type of thing, or is a VERY long 'translate' more of what I should be doing?

I want to truncate table partition but I'm getting error:
CODEORA-02266: unique/primary keys in table referenced by enabled foreign keys
because of table has a nested table. Currently this column is not in use so I could drop it, but I want to avoid it (table is huge). Is there another posibility to do truncate partitions in this table? ALTER TABLE ... SET UNUSED doesn't resolve the problem.

Background: Lost connection to Linux system while attempting SSO install. During reinstall installer states instance name already in use - suggests using different name.
Using deconfig.pl tool (user: cn=orcladmin) to remove SSO configuration, but error encountered. Reason: incorrect SYS password. Note: Can access db using SYS password with no problem.
