I am doing some ETL that I need to run "faster". The function in which I am interested removes low ascii code characters from a string. Please see the timing below and the definitions of the of the functions below those. I am selecting just the first 100K rows for testing and timing purposes only. In production, we are doing millions of records several times a day, thus the desire for "faster". Selecting with no functions is very fast, 0.2 seconds. We would really really want to convert at least 100K rows per second.
The best I can do is get it down to around five seconds using clear_nonlegal. That is, ironically, the one that I thought would be the slowest. It's making thirty-one calls to REPLACE. I would have guessed that the other two would be much faster. I am guessing that REPLACE is just much better optimized than TRANSLATE and, of course, my homegrown PL/SQL, which isn't optimized at all.
So, my question is thisif there is a way I can optimize my custom function, or maybe know of a better already optimized standard SQL and/or Oracle function that would do the job? I am thinking about trying to use a Java stored procedure, but I have never done that before, I am not currently set up for it, if it would be any faster anyway. Is Java faster with string manipulation the PL/SQL? I am thinking it would be really fast to call a C method,

how do I get the first three characters and last three characters from name field and remove all the junk characters from descd field?
I have an already populated table that refers to a wrong foreign key in another table. I have table abc that has the column fk_id. this column currently refers to column x_id1 in the table abc while it should refer to column x_id2 in xyz. I am trying to replace the data but I guess I miss something in the logic or the right way of doing it:
commit; insert all into abc values (10,'ab1',1) into abc values (11,'ab2',2) into abc values (12,'ab3',5) into abc values (13,'ab4',7) into abc values (14,'ab5',9) into xyz values (1,1,'d1') into xyz values (2,2,'d2') into xyz values (5,3,'d3') into xyz values (7,4,'d4') into xyz values (9,5,'d5') select * from dual; commit;
--this following select returns 5 rows
select * from abc, xyz where abc.fk_id = xyz.x_id1;
-- the following update only updates 3 rows and sets the other 2 -- to null!
update abc set fk_id = (select x_id2 from xyz where xyz.x_id1 = abc.fk_id); commit;
In forms 11 g, whenever, We did any menu change, and deploy in server, same changes are not reflecting in clients machine immediatly. I even stop forms services and restart.After some time... generally after 1 day, it reflect the new changes.In forms 10G, I never face this issue. As soon as i close the old menu and re-open, new changes reflect.
I am facing a simple problem, but could not resolve as yet, i want to replace two string 'M/S' and ' " ' with null, i know this command SELECT REPLACE(' " M/S Private linker " ','M/S',NULL) FROM dual Which command i should use
I can see that I can use REUSE_DATAFILES & TABLE_EXISTS_ACTION to overwrite tables by default, but is there a recognised way of replacing the entire DB with the impdp? Do I just create the instance, (with the init file) and not build/init the tables, or what? I'll experiment, but I'm just interested if there is a DBA best practice for this sort of thing.
Need to create or replace a Standard Sunguard package. When I'm executing, It is asking some series of parameters. when I cancel It is executing but the Web page is not opening giving error like PL/SQL: could not find program unit being called . Not understanding the exact error.
Getting starting with diving deeper into APEX and reading the developers guide all 800 pages of it! Thing is I'd like to get started with some of the more interesting stuff.
I have created a form page based on the "Form on a Table with Report". The report part looks fine. What I'd like to do now is use an API I've built to change how the insert and update works. So when the submit button is pressed it rather performs an API call to the procedure/function.
1. Should the API be a function or procedure. In my playing around I saw that a procedure might work better or easier to implement 2. How would I go about creating a call for the button to use instead of the current processes?

As I am doing a outer join, if the resource is not available on a particular day the resource_id is coming as NULL as it is not available. Is there any way to populate this NULL resource_id with the original resource_id as the resource_id is same for all the result set.
i want to replace 4 digit number in a given string with the same number incremented by 10000.
That mean in the given sting 1201 should be replace by 11201 (Icremented BY 10000).

How to merge multiple rows into single row (but multiple columns) efficiently.
For example
IDVal IDDesc IdNum Id_Information_Type Attribute_1 Attribute_2 Attribute_3 Attribute_4 Attribute_5 23 asdc 1 Location USA NM ABQ Four Seasons 87106 23 asdc 1 Stats 2300 91.7 8.2 85432 23 asdc 1 Audit 1996 June 17 1200 65 affc 2 Location USA TX AUS Hilton 92305 65 affc 2 Stats 5510 42.7 46 9999 65 affc 2 Audit 1996 July 172 1100
where different attributes mean different thing for each Information_type. For example for Information_Type=Location
Attribute_1 means Country Attribute_2 means State and so on.
For example for Information_Type=Stats
Attribute_1 means Population Attribute_2 means American Ethnicity percentage and so on.
I want to create a view that shows like below:
IDVal IDDesc IDNum Country State City Hotel ZipCode Population American% Other% Area Audit Year AuditMonth Audit Type AuditTime 23 asdc 1 USA NM ABQ FourSeasons 87106 2300 91.7 46 85432 1996 June 17 1200 65 affc 2 USA TX AUS Hilton 92305 5510 42.7 46 9999 1996 July 172 1100
I am attempting to select back multiple values for a specific key on one row. See the example below. I have been able to use the sys_connect_by_path to combine the fields into one field but I am unable to assign them to fields of their own. See the example below
TABLE DETAILS: Policy id plan name 111 A Plan 111 B Plan 111 Z Plan 112 A Plan 112 Z Plan
My desired result is to be able to show the output as follows
Policy ID Plan_1 Plan_2 Plan_3 111 A Plan B Plan Z PLan 112 A Plan Z PLan
I have set NLS_NUMERIC_CHARACTERS to ',.' but somehow during my java application life-cycle it got changed to '.,'! Is there any way to find what causes this? I can't find what or who change it. I have ordinary Java app which connects to Oracle 11.2.0.1.0 DB and as far as I know NLS_NUMERIC_CHARACTERS is not set explicitly or any other NLS_XXX setting. Is there any way to look in some logs for this?
I have a XML file which contains Japanese characters and it is parsed by a UNIX script and nawk utility and writes the data to a flat file separated by delimiter. I could the Japanese characters proper in the flat file.
I use SQLoader (within a unix script) to import this data from the flat file to Oracle database. If I view the data in the database through Toad, the Japanese characters are showing differently (not as in XML or in flat file).
But if do a export for the particular table to a flat file through Toad, I can see the Japanese characters proper in the exported flat file.
(Note : I have set the env variables NLS_LANG=Japanese_Japan.JA16SJIS, LC_CTYPE="en_CA.UTF-8" in both XML parser and the loader script)
Why I couln't see the Japanese characters while viewing through Toad.
Here's an odd problem. I'm trying to load German characters positionally (not CSV) using Linux 10g. I don't get this error on Windows or via CSV, but I'm bound to the method and platform.
The problem is simplified thus. I have 2 columns, the 1st varchar2(8) and the 2nd a numeric(3). The error I'm getting is Invalid number only on rows with special characters. Let me demonstrate.
The file has been loaded into Linux and corrected using iconv.
The 1st rows is accepted, but the second fails in sqlldr with
Record 2: Rejected - Error on table TEMP1, column FLD2. ORA-01722: invalid number
The logical assumption is that the double width character is not being properly read by sqlldr but I can find no advice on other setting. My nls parameters look like this.

I have one column name party_name containing Korean Characters and English characters.Some of the English characters have different symbols.My requirement is to get the data and exclude those symbols but not Korean characters.
Already I used a function to replace special symbols with space.The function contains code based on ASCII values it works good but it filters Korean characters too.the attachment of the screenshot, When I double click the name it shows with some question mark.
We are using Release 11.2.0.3.0 of Oracle. I am having below special characters inserted into one of my columns, how this value got inserted, (what is the source) i need to track it down.
We dont have any audit trigger on this table to track one level below. As per JAVA guys this is uploaded through a file and the file is having well defined characters and no special characters for this column value also they uploaded the file again but its now going fine with no such special characters. So they put it on DBA's to find how special characters came into database?
Again the editor is not recognising all the characters , so i got the ASCII value for each of the characters in the string, its as below.
String - ‡Mw‹O--ggÑ ÆÔéÓÞ³ µmT¤O ˆÓ`ôiyïÎ!Ž ASCII character is : ‡ ASCII Value Is : 14844065 ASCII character is : ‹ ASCII Value Is : 14844089 ASCII character is : -- ASCII Value Is : 14844052 ASCII character is : ASCII Value Is : 49793 ASCII character is : Ñ ASCII Value Is : 50065
I need to removed special characters (!, ", #, $, %, &, /, () from a string, i have a table with sll this special characters and words that i have to remove from the string.
How can i do that ?
i have a string with |R!$#&2-_D%2 and i want to get R2-D2
SELECT '|R!$#&2-_D%2' as Original, 'R2-D2' as Correct FROM DUAL
