Case insensitive search in select statement

Hi Experts,
I have entries in table as mixed case. For example i am searching on an attribute called description in the table. I want the serch to be case insensitive for that attribute. Because in table it is i.e. JUMBO Pack and in the search attribute it is i.e. Jumbo Pack.
I do not want to translate both to the same case and search. Is there an option?
Best Regards!
Sandip

Hi Sandip,
One more alternative:
If ztext is ur original field which is saving the mixed text.
Append one extra field(ztext_upper) to the table.
Now if " Sap Sdn" is the text we are saving then
While saving the entires to the table,
1. asusual save the value(" Sap Sdn") to teh original field(ztext)
2. translate the value to upper case(SAP SDN) and save this entry to teh newly appended field(ztext_upper)
Now while doing search, translate to upper case and compare with the value in ztext_upper. If it satisfies then for display options select the original value from the field (ztext) which is corresponding to the satisfied ztext_upper field.

Error in a report after enabling case insensitive search in conn pool prop

Hi All,
I put the below code in connection pool's connection string to enable case insensitive search.
alter session set NLS_SORT=BINARY_CI
alter session set NLS_COMP=LINGUISTIC
After putting this code one of my report started giving the below error which was working fine otherwise.

Case Insensitive Search coupled with "LIKE" operator.

Greetings All, I am running Oracle 11gR1 RAC patchet 25 on Windows X64.
This db supports and application that requires case insensitive searches.
Because there are a few entry points into the db I created an "after login" trigger:
CREATE OR REPLACE TRIGGER MyAppAfterLogon_TRGR
AFTER LOGON
ON DATABASE
DECLARE
vDDL VARCHAR2(200) := 'alter session set nls_comp=''linguistic''';
vDDL2 VARCHAR2(200) := 'alter session set nls_sort=''binary_ci''';
BEGIN
IF ((USER = 'MyAppUSER') OR(USER = 'MyAppREPORTINGUSER')) THEN
EXECUTE IMMEDIATE vDDL;
EXECUTE IMMEDIATE vDDL2;
END IF;
END MyAppAfterLogon_TRGR;
This ensures that everyone connecting to the DB via any mechanism will automatically have case insensitive searches.
Now, to optimize the know queries I created the standard index to support normal matching queries:
select * from MyTable where Name = 'STEVE';
The index looks like:
CREATE INDEX "CONTACT_IDX3 ON MYTABLE (NLSSORT("NAME",'nls_sort=''BINARY_CI'''))
This all works fine, no issues.
The problem is when I write a query that uses the "LIKE" operator:
select * from MyTable where Name like 'STEV%';
I get back the record set I expect. However, my index is not used? I can't for the life of me get this query to use an index.
The table has about 600,000 rows and I have run gather schema stats.
Does anyone know of any issues with case insensitive searches and the "LIKE" clause?
Any and all help would be appreciated.

I think there is issue with your logon trigger :
"IF ((USER = 'MyAppUSER') OR(USER = 'MyAppREPORTINGUSER')) THEN"
it should be :
IF UPPER(USER) = 'MYAPPUSER' OR UPPER(USER) = 'MYAPPREPORTINGUSER' THEN
because user name stored in Upper case. Check and try.

Possible to do case-insensitive searches?

G'day,
I was wondering if it's possible to do case-insensitive searches in oracle/HTMLDB?
I've tried what I thought would work
"select * from application where name like '%microsoft%'", this unfortunately doesn't return any records with a capital in it(eg "Microsoft").
If there is no way to do case-insensitive searches what is the best way around it?
Thanks
-Colin

Colin,
Yes it is possible to do case insensitive searches using SQL. Try, for example:
select * from application where upper(name) like '%ORACLE%'
The trick is to upper() both sides of the like operator.

Case insensitive search and "IN" Clause in Open SQL

Hi,
I have some doubts regarding Open SQL:
- Is there any support for Case Insensitive Search in Open SQL, is it availabe by default?
- Is there any restriction on number of elements in "IN" Clause, in Open SQL, is there any default number?
I have checked the [Open SQL Grammer |http://help.sap.com/saphelp_nwce711/helpdata/en/9b/f46cabaa874bc9a82234e8cf1d0696/frameset.htm]also, but nothing found there.

P.S I didn't find any other appropriate place to post this thread, let me know the correct categorization of Open SQL in case its wrong.

> I have some doubts regarding Open SQL:
I believe that you've questions and not doubts...
> - Is there any support for Case Insensitive Search in Open SQL, is it availabe by default?
Nope, there is nothing like that. By default all supported database use a bytewise equal operator - case insensitivness needs to be programmed by hand.
E.G. using UPPER(x)/LOWER(x) functions.
Be aware that this disables the possibilities of index usage.
> - Is there any restriction on number of elements in "IN" Clause, in Open SQL, is there any default number?
Yes, there is a restriction and it differes between the different DBMS.
Until recently you could have 2000 variables per statement with MaxDB.
The current versions of DBSL and MaxDB Kernel now support up to 10000 variables per statement.
Anyhow, in most cases, such a long in list can and should be avoided by using the FOR ALL ENTRIES construct. With this, the DBSL automatically splits the long IN list into smaller chunks and executes the statements several times.
This is invisible to the ABAP report - it just gets the result set as usual.
> P.S I didn't find any other appropriate place to post this thread, let me know the correct categorization of Open SQL in case its wrong.
I guess in anyone of the DB forums is Ok.

Doing case insensitive search

Is there any performant way to do case insensitive searches within the database other than using upper on the column?
If I use upper(col name) the index on the column is bypassed and hence this effects performance.
Is there any other way to do this.
Thanks
Vandana

In 10g rel.2 :
alter session set nls_comp=linguistic;
Execute your query; it should work for text search case insensitive
You can also use regular expression function like regexp_like() with match_option set to i:
select ename
from emp
where regexp_like(ename, k, i);

GetOrdinal of AseDataReader Class is not doing case-insensitive search

hi,
I am working on 12.5.4 version of sybase ASE.I am using 'Sybase.AdoNet2.AseClient.dll' to connect with database. I am using GetOrdinal method of ASEDatareader class (that as per documentation performs a case-sensitive lookup first. If it fails , a second search that is case-insensitive occurs) but in my case it is not performing case-insensitive search. I am attaching the document for your reference.
http://infocenter.sybase.com/help/index.jsp?topic=/com.infocenter.dc20066.1570100/doc/html/san1364409576274.html
Thanks,

Hi Monica,
Another thing you want to make sure is on your ASE that the oledb/adonet MDA scripts are up to snuff. Some of our fixes in the driver are in this.
If you login into the ASE and get the output of sp_version.
You should get something like this:
OLEDB MDA Scripts
         15.7.0.1250.1013/Wed Feb 19 UTC 00:28:47 2014
The ado.net driver and the older oledb driver use some specific MDA scripts on the ASE.
Read the coverletter of the SDK (Software Developers Kit for ASE). It explains how to update the MDA scripts. They are on the client side $sybase\ADONET\sp.
So where you downloaded the SDK you want to click Info then look for the README.
This is all the SDKs:
* Updating the metadata stored procedures required by ODBC, OLE DB and
jConnect Drivers on Adaptive Server Enterprise
Certain new features and bug fixes in ODBC, OLE DB and jConnect drivers
require you to modify the metadata stored procedures in Adaptive Server.
These stored procedures may not be up-to-date on your host ASE server due
to various reasons.
If the metadata stored procedures are outdated, you may not be able to use
some of the fixes that are implemented in this SP/ESD, so you will need to
manually install the updated metadata stored procedures.
To update the metadata stored procedures in Adaptive Server, first determine
the version of the meta-data scripts installed on the ASE. To do so, execute
the following command:
sp_version
go
The version number of the ODBC, OLE DB and jConnect meta-data scripts will
be displayed.
Review the version number column and compare it against the version of the
driver being used.
If the metadata scripts are outdated, the version installed will be older
than the driver build number or you will encounter one of the following:
- stored procedure sp_version is not found
- the stored procedure output does not print a row for the driver
The updated scripts are included with the drivers and can be installed as
follows:
For ODBC & OLE DB:
- Go the "sp" directory under the ODBC/OLE DB installation directory
- Execute the install_odbc_sprocs script for the ODBC Driver and
install_oledb_sprocs script for OLE DB Provider.
Syntax for using the script is:
        install_[odbc/olebd]_sprocs <ServerName> <username> [<password>]
         where <ServerName> is the name of the Adaptive Server
             <username> is the username to connect to the server
             [<password>] is the password the username
             (don’t supply this for null password)
For jConnect:
- Go to the "sp" directory under the jConnect installation directory. Based
on your host ASE server version, choose the appropriate SQL script.
- Use isql or another tool of your choice to execute the selected script.
This will install the current meta-data stored procedures.
Thanks,
Dawn

What is the best way to do a case insensitive search?

Hi Guys,
hopefully a quick one, anyone know what the best way to perform a case-insensitive search is? at the moment many of our stored procedures perform selects against un-indexed fields (e.g. product title) and to avoid casing problems we have an UPPER around the field name and the variable e.g.
AND (nvcproducttitle IS NULL OR
UPPER(p.NVCTITLE) LIKE '%' || UPPER(nvcproducttitle) || '%')
This seems to work just fine but on a large catalogue (10 million+) it can take 50-60 seconds to return.
Any pointers would be appreciated,
J

JYou could either ensure you have a function based index for your column e.g.
create or replace index fn_idx on prodtable (upper(nvctitle));
nb. syntax not checked
or you could use regular expressions. REGEXP_LIKE allows for case insensitive like searches.

Case insensitive search and replace using ASP and Oracle database

I am interested in providing a case insensitive search and replace query in a Active server page. At present data is collected from a html form which passes the text values to a ASP page. The ASP page runs a search (select query) to find if the data is already in the Oracle database, if it isn't the ASP page runs sql (INSERT) to insert the record, if not the page returns a form indicating that the record already exists. At present we can convert the case of new records using the VB UCase() function. But can't do a insensitive search with the existing records. *The Query must be able to utilize ASP variables.
Any help would be much appreciated.

I can't check your script right now since I'm not on Mac. I recommend you to use FindChangeByList script for CS4 instead (it works with CS3): http://forums.adobe.com/servlet/JiveServlet/download/2080627-12695/FindChangeByListCS4.zip together with Martin Fisher's: http://www.kasyan.ho.com.ua/downloads/RecordFindChange_CS3_Kas.zip
Use this script to record settings from Text and GREP tabs, then copy and paste them into FindChandgeList.txt file.
Or, optionally you can use this script: http://www.kasyan.ho.com.ua/find_change_by_queries.html.

Case insensitive search in SE16

Hello Community,
We have a Z table which contains the field "filename," containing both upper & lowercase alphanumeric values.
I was surprised to find that it is not so easy to perform a case insensitive search against those field values using SE16.
It would be perfect if:
1. a search in SE16 for `file.txt` will find the results of all records related to the file "file.txt"
2. a search in SE16 for `FiLe.TxT` will also find all records related to the file "file.txt"
Can someone help me to accomplish this ?
Thanks!
Keith Helfrich

Hi everyone,
The goal is to perform a case insensitive search in SE16. Is there no way to do this ?
While there are a variety of work-arounds, for example : it is possible to store all the values in the table in UPPERCASE, these work-arounds do not solve our problem.
The values in the table need to be stored with the accurate case, exactly as the file is named at the UNIX level. Since UNIX is also case sensitive, we need to be accurate with the case when storing statistics data about the files.
Yet, when searching in SE16, it is problematic because we don't always know the correct case. For that reason, a case insensitive search is required.
This seems to be a very basic function that I am surprised SAP doesn't provide...

When you are querying any strings, it is always case sensitive.
Is there any restriction on number of elements in "IN" Clause, in Open SQL, is there any default number?
I don't think there area any. IN opearator works like combined ORs and here you don't have any restrictions in fields number.

Case insensitive search working in dev but not in prod

Hello All,
I had set the CASE_SENSITIVE_CHARACTER_COMPARISON parameter as OFF in NQSConfig.ini file for enabling the case insensitive search in OBIEE.
This setup is letting me do the case insensitive search in Dev env but the same doesnt work in prod env. I tried pointing both prod and dev rpd to same prod db.
With same db also, case insensitive search doesnt work in prod env.
Any idea for which other configuration I can look for.
Thanks in advance.

Thanks Stijin. I had seen this post earlier. Case insensitive search works fine after setting the value for NLS_SORT and NLS_COMP in production RPD but the other report with distinct clause starts failing. Not sure about the reason.
Saw this comment from you in that post:
The only compromise solution we could find was to "cache" the column value we wanted to use in insensitive searches. These were mainly used in "show all choices" while setting prompts. Other than that there isn't much you can do in an Oracle database.
Can you please tell me how to implement the above.

Case insensitive search on subject name to retrieve a certificate from key chain.

Hi,
I need to find the client certificate from key chain based on the subject name.
Currently, I am using attribute kSecLabelItemAttr and providing the subject name to create the attribute list for the API "SecKeychainSearchCreateFromAttributes" which gives the certificate.
Problem: This certificate search is case sensitive for the subject name.
Question: Is there a way to do a case insensitive search on a subject name to get a certificate on snow leopard? I found the attribute "kSecMatchCaseInsensitive" which works with key "kSecClassCertificate" in the API "SecItemCopyMatching", but the key kSecClassCertificate is only available for 10.7 and later.

I think there is issue with your logon trigger :
"IF ((USER = 'MyAppUSER') OR(USER = 'MyAppREPORTINGUSER')) THEN"
it should be :
IF UPPER(USER) = 'MYAPPUSER' OR UPPER(USER) = 'MYAPPREPORTINGUSER' THEN
because user name stored in Upper case. Check and try.

Case-Insensitive Searching on Content Server

Hello everyone,
I have a Content Server 10gr3 using an Oracle 11g DB. All of my searches are case sensitive, but we need case-insensitive searching. I've tried changing the DatabasePreserveCase variable in the config.cfg to 1, 0, true, and false, rebuilt the indexes in between each reboot (not sure if that's necessary or not), tried checking in new documents after making the changes and searching for those, but no matter, searches stay case sensitive.
We have another UCM install running on a 10.2.0.3.0 DB, and case insensitivity works on that Content Server with DatabasePreserveCase=1.
What could we be doing wrong? I've found several documents which have stated that case-insensitivity is impossible with an Oracle DB, but I think those are all old and from before Oracle's acquisition of the product (and obviously it is possible, since we have another install with it working).
Thanks in advance for any help you can give!

I'm not quite sure what you mean by Search Engine... we simply installed the Oracle 11g Database, then installed Content Server and configured it to run using that database. We haven't done anything with full-text search.
Edit: Do you mean the SearchIndexerEngineName value in the config file? It's DATABASE.METADATA, though at some point we also need to get full-text up and running which to my understanding requires it to be DATABASE.FULLTEXT.
As to the OracleCaseInsensitiveSearch component, where can I find it? Google shows up nothing, and MetaLink has one page saying that it exists but nothing more...
