SQL & PL/SQL :: Regex Replace Case Insensitive?
Nov 11, 2010
replace a occurence of a string by case insensitive search For eg.
String | Replaced String
----------------------------------|----------------------------
I am NEW.USER to regex | I am NOTSONEW.USER to regex
I am NEWBIE.USER to regex | I am NOTSONEW.USER to regex
I am part of newer.users of regex | I am part of NOTSONEW.users of regex
Essentially am trying to look for case-sensitive occurence of the string NEW%. and replacing it with NOTSONEW.

we are implementing case insensitive seaarch in our small 10g database...We would be modifying the following parameters.
nls_comp=LINGUISTIC ;
nls_sort=binary_ci;
We want to use the existing indexes and as I understand we will need indexes created in following manner
create index <index_name> on <table_name>(nlssort( <column_name>, 'NLS_SORT=BINARY_CI'));
1) Is there any mechanism with which we can convert existing index to above type? (without drop and recreate)One of the issue I can see is related to unique values as 'ABC', 'Abc' and 'abc' would be treated same
2) Apart from that is there any issue, added maintenance for such index?

I am trying to delete duplicate or repeating words in a string using regular expressions (regex) and an Oracle database.I have Googled quite a bit on this topic and was unable to track down something that fit the bill or remotely came close to paying the tip.
A pattern would be: word word start with newThe final string should look like this: word start with new Basically all the strings begin with the two words repeating.

I have a table MOM i.e. Minutes of meeting where important points in a meeting are captured. Now these points may include words like, "don't" or "can't" which will be recorded first in a text file and later copied to the table MOM. Rest of the details are unimportant. All I want to know is how do I enter these words without getting the ORA-01756 error? Do I need to always correct them before entering or is there perhaps another way?

TestCase
DROP TABLE test ;
CREATE TABLE test (id NUMBER, cnt_str VARCHAR2(200));
INSERT INTO test (id, cnt_str) VALUES
(1,'AKRN000002,1451-1473,00000A,74,AKRN000002,1475-14791000000A,8010AKRN000002,1481-1492,00000A,9310AKRN000002,1494-1500')
[code]...
The requirement is in each of the string where there is comma after the number and the number is prefixed by "-" character,
the comma after the number should be replaced by '10'.
For example in the second record where ID = 2,
CNT_STR is '00000B,1-251000000D,26-32,ADTW000301,2858-2875'.
In this string -32, should become -3210 and resulting string should be '00000B,1-251000000D,26-3210ADTW000301,2858-2875'
Expected Result.
ID CNT_STR
-------- -------------------------------------
1 AKRN000002,1451-14731000000A,7410AKRN000002,1475-14791000000A,8010AKRN000002,1481-14921000000A,9310AKRN000002,1494-1500

For example i've a select query as below.
1.select store_name, store_id from stores
2.select store_name, (select store_id from inventory where store_id=<somevalue>) from stores
3. select store_name, store_id from stores
where store_id in(select store_id from stores1)
based on above examples i need to replace all the columns(oly the column names not the column names in the subquery) in a sql query .
is there is any oracle function to achieve this?
and the result shud be as follows if i replace with STORE_DET.
1.select STORE_DET from stores
2.select STORE_DET from stores
3. select STORE_DET from stores
where store_id in(select store_id from stores1)

I have a string. For example "I have too many files. There are 1000 files. I have to delete them." Sometimes the string can be "I have too many files. There are 115003 files. I have to delete them." Whatever the srting is, I need to change the string to "I have too many files. There are 10 files. I have to delete them." replace the "1000" or "115003" to "10". This portion of the string is always an integer. I use Oracle 11G2.

I'm starting to Oracle and am having a doubt, need to check if a variable is null if I need to make an appointment if you do not need to make another appointment. I thought I was doing fine, but Oracle is pointing this error: "ORA-00900: invalid SQL statement."

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.

select substr(ename,1,8),case when length(sal)=2
then '**'

replace the first 5 commas with the character '|' in the below string:
'Red, White, Blue, Purple, Pink, Green, Yellow, Gold and many others, like Black and Silver'
I tried:
SELECT regexp_replace('Red, White, Blue, Purple, Pink, Green, Yellow, Gold and many others, like Black and Silver',
',','|',1,5) from dual
but it only replaces the 5th comma.

I need to create a procedure which inserts values from a temporary table into the main table the columns names in temporary table are same for all temporary tables only the table name will be replaced the skeleton procedure code will look like this.
create or replace procedure load_data as
select c_tables is select table_name from user_tables
where table_name like 'TEST%';
V_tbl varchar2(30);
BEGIN
OPEN C_TABLES;
LOOP
FETCH C_TABLES INTO V_TBL;
[code].....
The logic here is to insert values from v_tbl variable table into sales_target table.
when I compile it doesn't like using V_TBL variable in the procedure?

I am using regexp_replace function to replace the string between the double quotes with the first occurance but i am able to replace first occurance but I am not getting remaining string.
For example:

I am using the oracle 10g, I am trying to write the a sql query by which in a below mention patterns I can replace the digits after a string 'CVV' with X. The no of X will be equal to the no of digits after CVV
1. BTA CVV 8810
2. VISA PARTICULAR CCVIXXXXXXXXXXXX5474/1012 CVV498
3. C***CVV VI 569***
4. dskdfjdkgjdfk: FP CCVI,XXXXXXXXXXXX0031/0711/CVV 063/dffddf:dfdfdfd
5. (T) CVV 4671
6. MS-ACEEML/CVV
7. O/AXXXXXXXXXXXX1007EXP1210/CVVXXXXXXXXXXX4664/MEETING CARD FOR AMEX PARTNER OFFICES
AFTER a change above data should look like as mentioned below
1. BTA CVV XXXX
2. VISA PARTICULAR CCVIXXXXXXXXXXXX5474/1012 CVVXXX
3. C***CVV VI XXX***
4. dskdfjdkgjdfk: FP CCVI,XXXXXXXXXXXX0031/0711/CVV XXX/dffddf:dfdfdfd
5. (T) CVV XXX
6. MS-ACEEML/CVV -- no change for this
7. O/AXXXXXXXXXXXX1007EXP1210/CVVXXXXXXXXXXX4664/MEETING CARD FOR AMEX PARTNER OFFICES --- -- no change for this
Initially I tried to find the position of CVV in any string and then from that position take the digit and replace them with X. I tried the below code which is not complete
select REGEXP_INSTR('BTA CVV XXXX','CVV',1,1) from dual;

I am about to pass 1Z0-051 and have been cramming. Ran across this scenario: Create or replace view. Correct answer: allows insert from view in multitable insert statement. Can I actually insert data from a view? My understanding is no data actually exists in a view. This has created a cavernous feeling of inadequacy.
