How to serch a character string in a BLOB (case insensitive)

Hi
Could somebody help me with this please.
I need to search for the existance of a character string in a BLOB column of a table.
I can do it in the below way.
PROCEDURE search (in_search VARCHAR2) IS
lob_doc BLOB;
Pattern VARCHAR2(30);
Position INTEGER := 0;
Offset INTEGER := 1;
Occurrence INTEGER := 1;
BEGIN
Pattern := utl_raw.cast_to_raw(in_search);
SELECT BLOB_CONTENT INTO lob_doc
FROM documents WHERE ein = '702265981';
DBMS_LOB.OPEN (lob_doc, DBMS_LOB.LOB_READONLY);
Position := DBMS_LOB.INSTR(lob_doc, Pattern, Offset, Occurrence);
IF Position = 0 THEN
DBMS_OUTPUT.PUT_LINE('Pattern not found');
ELSE
DBMS_OUTPUT.PUT_LINE('The pattern occurs at '|| position);
END IF;
DBMS_LOB.CLOSE (lob_doc);
END search;
But the problem is, it does a case sensitive search.
I need a case-insensitive search
Thanks in Advance

The best way would be to use Oracle Text.
However, if you want a quick and dirty solution, I would convert to CLOB, and (assuming 9i) you can use LOWER on the CLOB.

You should really check the API first:

How can I wire a string value to the case selector terminal and depending on that value, execute a selected case?

Hi Everyone
In the block diagram of the posted VI, thru serial comm, byte #2 is either 00 or 01 (Hex). This byte should dictate which case to execute. If Hex value = 00 executes case #1, If Hex value = 01 executes case #2. If neither, nothing should execute.
How can I do this? I am fairly new to LabVIEW any feedback is highly appreciated.
Thanks
Mahir
Solved!

easier to just wire in the integer to the case structure rather than convert to string.
Then just go up to the case selector and type what you want.

How to convert character string into ascii format correctly

dear all
I'm using encryption technique in my application(oracle formas 6i). character stream convert to the ascii format and add some numeric value and again convert to the character format
>>>>
here I'm using ASCII and CHR functions.
>>>>
.net program also using same algorithm to encrypt this password.....finally both the character strings are not equel.(This happens if the character string's ascii value greater than 127. otherwise both are equel).
pls give me a solution for this
thanks and regards
buddhike

hir dear
do u want to encrypt & dcrypt your password.which version of oracle you are using
first store these procedure in Oracle Databases: dbms_obfuscation_toolkit, dbms_crypto, Transparent Data Encryption
now u can use these procedure to encrypt & dcrypt your password
if you any query about those procedures you can ask me

There is not a chance in the world, especially not knowing column definitions that I, and I suspect most anyone else, is going to wade through this much unformated code looking for an error you couldn't bother to copy in full.
Either tell us, specifically, the line on which the error is occurring or, better yet, start whacking stuff out of your code until you find the offending definition. That is certainly what I would do. Commenting out sections is a marvelous way to quickly find an issue.

ORA-06502 (character string buffer too small) on import application via script

Running apex 4.2.2.00.11
oracle 10.2.0.5
I'm using a script to import my development application to a few production applications.
It worked great on apex 4.1.1, but now I get an 'ORA-06502 PL/SQL numeric of value error: character string buffer too small'
In the command window, I see that the script fails after it starts on the plugins.
My question: is this a bug in 4.2.2?
I could be a incompatible plugin, but how can I found out which plugin?
My script is quite simple:
In a command window I run

How to insert special character from Oracle form builder 10g

Dear all,
I need help. how to insert special character like 'Superscript or Subscript ' from oracle form builder 10g. I had try in Oracle form builder 6i with press ALT+ASCII code in the text item and it work, but in the oracle form builder 10g this method doesn't work... would you like to help me...somebody please...
Best Regard,
Dedy P.T.

What do you mean by insert ... from Forms Builder? Do you mean you want to add it as text in a string of pl/sql code or as part of boiler plate text (label) or a value on the Property Palette?
For special characters you would need set NLS_LANG to something that would support the characters you want to use. For the Builder to see the change, you would need to set NLS_LANG to something like:
NLS_LANG=AMERICAN_AMERICA.UTF8
This can be done in the Windows Registry or system. As I mentioned, this will only apply to the Builder and will have nothing to do with a running form. For running forms you would need to set this in default.env. As for things like super and sub scripts, these are font formats and not necessarily characters. For the most part, I don't believe these are supported in Forms.

Character string buffer too small (select list query based LOV)

Hi,
Using the select list query based LOV with a select witch is too big, you get this error.
report error:
ORA-20001: Error fetching column value: ORA-06502: PL/SQL: numeric or value error: character string buffer too small
When using the Popup LOV query based LOV) then it works nice.
Can that be solved somehow?
With the Popup LOV the return value is displayed in stead of the description.

Hi Andy,
How do I incorporate your suggestion on a report ?
Example : I have
select apex_item.display_and_save(1,column1,5) col1,
apex_item.display_and_save(2,column2,5) col2 ,
apex_item.popup_from_query(3, emp_name, 'select user_name, name empname from table2) col3
Table 2 is a long list , and I'm getting string buffer too small due to this.
Your suggestion with HTP is good but I'm not sure how to implement it for reports as I'll like the user to change the values with the select_list.
I'm not using forms as they want mulit-record on the same page.
Hope to hear back from you soon.
Thanks very much.

Hi Helios,
Many thanks for your reply.
I am able to figure out the issue. In the code we have
l_analysis_report := l_analysis_report ||'<tr><td align="center">'|| curr_refresh.analysis_name
 || '</td><td align="center">' || curr_refresh.start_time || '</td><td align="center">'
 || curr_refresh.end_time || '</td><td align="center">'|| curr_refresh.RUN_TIME_SECS ||
 '</td><td align="center">'|| curr_refresh.status ||
 '</td> </tr>' || UTL_TCP.CRLF;
 exit when length (l_analysis_report) > 32500;where "l_analysis_report VARCHAR2(32767);"
The issue is report has more characters, and when executing it throws the error " ORA-06502: PL/SQL: numeric or value error: character string buffer too small ".
Can you please let me know how to have more characters/data in the report. Will CLOB help if yes, please let me know how to use it.
Kindly suggest some options.
Regards,
Sunny

ASCII character/string processing and performance - char[] versus String?

Hello everyone
I am relative novice to Java, I have procedural C programming background.
I am reading many very large (many GB) comma/double-quote separated ASCII CSV text files and performing various kinds of pre-processing on them, prior to loading into the database.
I am using Java7 (the latest) and using NIO.2.
The IO performance is fine.
My question is regarding performance of using char[i] arrays versus Strings and StringBuilder classes using charAt() methods.
I read a file, one line/record at a time and then I process it. The regex is not an option (too slow and can not handle all cases I need to cover).
I noticed that accessing a single character of a given String (or StringBuilder too) class using String.charAt(i) methods is several times (5 times+?) slower than referring to a char of an array with index.
My question: is this correct observation re charAt() versus char[i] performance difference or am I doing something wrong in case of a String class?
What is the best way (performance) to process character strings inside Java if I need to process them one character at a time ?
Is there another approach that I should consider?
Many thanks in advance

>
Once I took that String.length() method out of the 'for loop' and used integer length local variable, as you have in your code, the performance is very close between array of char and String charAt() approaches.
>
You are still worrying about something that is irrevelant in the greater scheme of things.
It doesn't matter how fast the CPU processing of the data is if it is faster than you can write the data to the sink. The process is:
1. read data into memory
2. manipulate that data
3. write data to a sink (database, file, network)
The reading and writing of the data are going to be tens of thousands of times slower than any CPU you will be using. That read/write part of the process is the limiting factor of your throughput; not the CPU manipulation of step #2.
Step #2 can only go as fast as steps #1 and #3 permit.
Like I said above:
>
The best 'file to database' performance you could hope to achieve would be loading simple, 'known to be clean', record of a file into ONE table column defined, perhaps, as VARCHAR2(1000); that is, with NO processing of the record at all to determine column boundaries.
That performance would be the standard you would measure all others against and would typically be in the hundreds of thousands or millions of records per minute.
What you would find is that you can perform one heck of a lot of processing on each record without slowing that 'read and load' process down at all.
>
Regardless of the sink (DB, file, network) when you are designing data transport services you need to identify the 'slowest' parts. Those are the 'weak links' in the data chain. Once you have identified and tuned those parts the performance of any other step merely needs to be 'slightly' better to avoid becoming a bottleneck.
That CPU part for step #2 is only rarely, if every the problem. Don't even consider it for specialized tuning until you demonstrate that it is needed.
Besides, if your code is properly designed and modularized you should be able to 'plug n play' different parse and transform components after the framework is complete and in the performance test stage.
>
The only thing that is fixed is that all input files are ASCII (not Unicode) characters in range of 'space' to '~' (decimal 32-126) or common control characters like CR,LF,etc.
>
Then you could use byte arrays and byte processing to determine the record boundaries even if you then use String processing for the rest of the manipulation.
That is what my framework does. You define the character set of the file and a 'set' of allowable record delimiters as Strings in that character set. There can be multiple possible record delimiters and each one can be multi-character (e.g. you can use 'XyZ' if you want.
The delimiter set is converted to byte arrays and the file is read using RandomAccessFile and double-buffering and a multiple mark/reset functionality. The buffers are then searched for one of the delimiter byte arrays and the location of the delimiter is saved. The resulting byte array is then saved as a 'physical record'.
Those 'physical records' are then processed to create 'logical records'. The distinction is due to possible embedded record delimiters as you mentioned. One logical record might appear as two physical records if a field has an embedded record delimiter. That is resolved easily since each logical record in the file MUST have the same number of fields.
So a record with an embedded delimiter will have few fields than required meaning it needs to be combined with one, or more of the following records.
>
My files have no metadata, some are comma delimited and some comma and double quote delimited together, to protect the embedded commas inside columns.
>
I didn't mean the files themselves needed to contain metadata. I just meant that YOU need to know what metadata to use. For example you need to know that there should ultimately be 10 fields for each record. The file itself may have fewer physical fields due to TRAILING NULLCOS whereby all consecutive NULL fields at the of a record do not need to be present.
>
The number of columns in a file is variable and each line in any one file can have a different number of columns. Ragged columns.
There may be repeated null columns in any like ,,, or "","","" or any combination of the above.
There may also be spaces between delimiters.
The files may be UNIX/Linux terminated or Windows Server terminated (CR/LF or CR or LF).
>
All of those are basic requirements and none of them present any real issue or problem.
>
To make it even harder, there may be embedded LF characters inside the double quoted columns too, which need to be caught and weeded out.
>
That only makes it 'harder' in the sense that virtually NONE of the standard software available for processing delimited files take that into account. There have been some attempts (you can find them on the net) for using various 'escaping' techniques to escape those characters where they occur but none of them ever caught on and I have never found any in widespread use.
The main reason for that is that the software used to create the files to begin with isn't written to ADD the escape characters but is written on the assumption that they won't be needed.
That read/write for 'escaped' files has to be done in pairs. You need a writer that can write escapes and a matching reader to read them.
Even the latest version of Informatica and DataStage cannot export a simple one column table that contains an embedded record delimiter and read it back properly. Those tools simply have NO functionality to let you even TRY to detect that embedded delimiters exist let alone do any about it by escaping those characters. I gave up back in the '90s trying to convince the Informatica folk to add that functionality to their tool. It would be simple to do.
>
Some numeric columns will also need processing to handle currency signs and numeric formats that are not valid for the database inpu.
It does not feel like a job for RegEx (I want to be able to maintain the code and complex Regex is often 'write-only' code that a 9200bpm modem would be proud of!) and I don't think PL/SQL will be any faster or easier than Java for this sort of character based work.
>
Actually for 'validating' that a string of characters conforms (or not) to a particular format is an excellent application of regular expressions. Though, as you suggest, the actual parsing of a valid string to extract the data is not well-suited for RegEx. That is more appropriate for a custom format class that implements the proper business rules.
You are correct that PL/SQL is NOT the language to use for such string parsing. However, Oracle does support Java stored procedures so that could be done in the database. I would only recommend pursuing that approach if you were already needing to perform some substantial data validation or processing the DB to begin with.
>
I have no control over format of the incoming files, they are coming from all sorts of legacy systems, many from IBM mainframes or AS/400 series, for example. Others from Solaris and Windows.
>
Not a problem. You just need to know what the format is so you can parse it properly.
>
Some files will be small, some many GB in size.
>
Not really relevant except as it relates to the need to SINK the data at some point. The larger the amount of SOURCE data the sooner you need to SINK it to make room for the rest.
Unfortunately, the very nature of delimited data with varying record lengths and possible embedded delimiters means that you can't really chunk the file to support parallel read operations effectively.
You need to focus on designing the proper architecture to create a modular framework of readers, writers, parsers, formatters, etc. Your concern with details about String versus Array are way premature at best.
My framework has been doing what you are proposing and has been in use for over 20 years by three different major nternational clients. I have never had any issues with the level of detail you have asked about in this thread.
Throughout is limited by the performance of the SOURCE and the SINK. The processing in-between has NEVER been an issu.
A modular framework allows you to fine-tune or even replace a component at any time with just 'plug n play'. That is what Interfaces are all about. Any code you write for a parser should be based on an interface contract. That allows you to write the initial code using the simplest possible method and then later if, and ONLY if, that particular module becomes a bottlenect, replace that module with one that is more performant.
Your intital code should ONLY use standard well-established constructs until there is a demonstrated need for something else. For your use case that means String processing, not byte arrays (except for detecting record boundaries).
