SQL & PL/SQL :: How To Find Whether Exact String Is Present / Not In Given String
Mar 14, 2013I'm facing some problem even after using INSTR function in Oracle.The problem is I have written the logic in the PL/SQL block which appends all the values fetched in a loop on the basis of whether the string is present or not.
For ex:
The first value fetched from the select query first is ABCDEFG which gets appended to a variable
The next value fetched is AB even this has to be appended to the variable since this exactly doesn't match with ABCDEFG.
The next value fetched is BCDEF even this has to be appended to the variable since this exactly doesn't match with ABCDEFG.
The third Value fetched is ABCDEFG this will not get appended presently according to the logic which is correct.
writing that piece of code to append the value fetched which doesn't exactly match with the existing string

View 1 Replies View RelatedJapanese Characters In Oracle
Jun 22, 2013I 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.
10g SQLLoader With Multibyte Characters
May 11, 2011Here'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.
[oracle@basic sqlldr]$ cat jh.txt

This is the loader control file
[oracle@basic sqlldr]$ cat jh.ctl
load data

infile 'jh.txt'
replace into table TEMP1
(
FLD1 POSITION(1:8) CHAR,
FLD2 POSITION(9:11)
)
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.

SQL & PL/SQL :: How Special Characters Got Inserted Into DB
Jul 9, 2013We 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

SQL & PL/SQL :: Replacing Multiple Characters?
May 21, 2013I 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,

SQL & PL/SQL :: Detecting Hidden Characters
Jul 31, 2011I am not sure if the problem is related to hidden characters but its my best guess so far. I am trying to enhance a part of the ERD by creating a lookup for a column one of the table that uses text (finite set of values).
CREATE TABLE N_AGREEMENT_STATUS
(
STATUS_ID NUMBER(2) PRIMARY KEY,
STATUS_NAME VARCHAR2(10 BYTE)
);
INSERT ALL
INTO N_AGREEMENT_STATUS VALUES (1, 'INACTIVE')
INTO N_AGREEMENT_STATUS VALUES (2, 'ACTIVE')
INTO N_AGREEMENT_STATUS VALUES (3, 'CLOSED')
INTO N_AGREEMENT_STATUS VALUES (4, 'CANCELLED')
SELECT * FROM DUAL;
when I try to update the source table no update takes place (0 records updated) if I used the following statement:
ALTER TABLE N_AGREEMENT ADD STATUS_ID NUMBER(2);
UPDATE N_AGREEMENT SET STATUS_ID =
(
SELECT STATUS_ID
FROM N_AGREEMENT_STATUS
WHERE N_AGREEMENT.STATUS = STATUS_NAME );
but it works fine only if I used:
UPDATE N_AGREEMENT SET STATUS_ID =
(
SELECT STATUS_ID
FROM N_AGREEMENT_STATUS
WHERE N_AGREEMENT.STATUS LIKE STATUS_NAME || '%'
);
The strange thing is that when I use:
SELECT N_AGREEMENT.STATUS, N_AGREEMENT.STATUS_ID
FROM N_AGREEMENT
WHERE N_AGREEMENT.STATUS = 'ACTIVE';
it returns correct results and all status = 'ACTIVE' appear correctly!
