10g SQLLoader With Multibyte Characters

May 11, 2011

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.

[oracle@basic sqlldr]$ cat jh.txt
ELEKTROM001
ZEIPR�SI002

This is the loader control file

[oracle@basic sqlldr]$ cat jh.ctl
load data
characterset utf8
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.
My nls parameters look like this.

PARAMETER VALUE
------------------------------ ------------------------------
NLS_LANGUAGE ENGLISH
NLS_TERRITORY UNITED KINGDOM
NLS_CURRENCY #
NLS_ISO_CURRENCY UNITED KINGDOM
NLS_NUMERIC_CHARACTERS .,
NLS_CALENDAR GREGORIAN
NLS_DATE_FORMAT DD-MON-RR
NLS_DATE_LANGUAGE ENGLISH
NLS_CHARACTERSET UTF8
NLS_SORT BINARY
NLS_TIME_FORMAT HH24.MI.SSXFF

PARAMETER VALUE
------------------------------ ------------------------------
NLS_TIMESTAMP_FORMAT DD-MON-RR HH24.MI.SSXFF
NLS_TIME_TZ_FORMAT HH24.MI.SSXFF TZR
NLS_TIMESTAMP_TZ_FORMAT DD-MON-RR HH24.MI.SSXFF TZR
NLS_DUAL_CURRENCY ?
NLS_NCHAR_CHARACTERSET UTF8
NLS_COMP BINARY
NLS_LENGTH_SEMANTICS CHAR
NLS_NCHAR_CONV_EXCP FALSE

I've tried using other sqlldr options such as LENGTH SYMANTICS and BYTEORDER but with no success.

SQLloader Database Saturation?

Jul 2, 2013

I have a situation i can't find an explanation for, here it is:

I have a table, lets say:
table_a
-------------
name
last name
dept
status
notes

And this table has a trigger on insert, which does a lot of validation to the info to change the status field of the new record according to the results of the validation, some of the validations are:

○check for the name existing in a dictionary
○check for the last name existing in a dictionary
○check that fields (name,last name,dept) aren't already inserted in table_b... and so on

The thing is, if i do an insert on the table via query, like

insert into table_a
(name,last_name,dept,status,notes)
values
('john','smith',1,0,'new');

it takes only 173 ms to do all the validation process, update the status field and insert the record in the table. (the validation process does all the searches via indexes)But if i try this via SQLloader, reading a file with 5000 records, it takes like 40 minutes to validate and insert 149 records (of course i killed it...)i tried loading the data disabling the trigger (to check speed) and i got that it loads like all the records in less than 10 seconds.

So my question is, what can i do to improve this process?, my only theory is that i could be saturating the database because it loads so fast and launches many instances of the trigger, but i really don't know.

My objective is to load around 60 files with info and validate them through the process in the trigger (willing to try other options though).

Server Utilities :: CONCAT Fails In SQLLoader?

Mar 2, 2010

I'm trying to concatenate a local phone number field. The LDAP system only has the last 5 digits but for the directory database we need all 7 digits.I've tried every combination I can think of to get the concatenation to work but every combination results in just the first two digits being imported, e.g.,

LOCAL_NUM "'20'||:local_num",

results in just 20 being imported. Every iteration I've tried that didn't result in an error imported only the 20 and ignored the ||. I've also tried calling the CONCAT directly, e.g.,

LOCAL_NUM "CONCAT('20', :local_num)",

result is the same.The problem seems to be that the loader is ignoring the concatenate statement all together. I've tried the statements outside of the loader via sqlplus with expected result so I'm confused as to why it's not working within the loader.

Application Express :: Uploading Multibyte CSV File?

Jul 9, 2012

I have multibyte CSV files (extract from BI) : Excel says "Unicode txt" and when I save them from Excel in "Text CSV", they get half the size on the disk.

here is the piece of code where the uploaded file get converted from blob to clob then to varchar2 (CSV Util from Oleg.Lihvoinen [URL]...

SELECT blob_content
INTO v_blob_data
FROM wwv_flow_files
WHERE NAME = p_file_name;

[code]...

I have tried different values for "blob_csid := 873 ;" (and by the way, the list of possible values for this code is very difficult to find : I know, there is a function CS_name to CS_ID but a list would be great), but without any visible effect.If I use the Apex CSV uploader app, the result is the same than with this code.

is an example :
�O�R�A�C�L�E�

instead of :
ORACLE

How I can have these files imported whithout an Excel conversion ?

Server Utilities :: Return A Column Value Using Sqlloader After Loading

Dec 1, 2011

I have the following table intra_trades with t_id as the primary key. There is a trigger on that table that gets the next sequence and inserts it into the t_id column for every insert. I need to load data into that table using SqlLoader as chunks of 3000 rows and return the t_id back the script that Sqlload the data so that it can use that t_id's for the next process in the script.

intra_trades
t_id NUMBER(15) pk
t_name VARCHAR2(30)
t_loc VARCHAR2(40)
t_start TIMESTSTAMP
t_end TIMESTSTAMP
[code]....

The problem is that the only unique key on that table is the t_id which has a sequence on it and it is the pk. There can be duplicate rows in that table to meet the business needs for the company. So it is hard to associate the rest of the data in a row with t_id. The only thing I can think of is return the t_ids in the order it inserted so if the script keeps the order of rows in the memory it can associate the tid with the rest of the intra_trades info.How can I make the sqlloader return an array of t_ids that inserted? I need to return the t_ids's in the order it inserted so that the script can associate the t_id with the rest of the rest of the data in a row.

SQL & PL/SQL :: Characters Format On The Web?

We have a production database that have : NLS_LANGUAGE=FRENCH_FRANCE.WE8ISO8859P1.

We use (INSERT, UPDATE) arabic and french languages, and it works properly.

When I issue SQL statments to retrieve arabic data (with SQL*PLUS), it works and it returns correct arabic format.

When I use PHP, with the same small query, the arabic format is not correct.

I've tried changing the encoding characters on my browsers (IE and FF) and it's still incorrect.

Japanese Characters In Oracle

Jun 22, 2013

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.

I understood how to restrict special characters or spaces .

This function allow only characters and numbers in English language and doesnt allow special characters.

I need to restrict further by not allowing any other language characters or numbers except only english alphanumeric letters.

SQL & PL/SQL :: How Special Characters Got Inserted Into DB

Jul 9, 2013

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--ggсÆÔéÓÞ³µmT¤OˆÓ`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

SQL & PL/SQL :: Replacing Multiple Characters?

May 21, 2013

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,

SQL & PL/SQL :: Detecting Hidden Characters

Jul 31, 2011

I 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!

Removing Illegal Characters

Dec 27, 2006

I am working with Oracle 10G, and have been working on setting up little pl/sql checks to make sure that the data that is imported is in the correct format.

The wall I have hit is removing illegal characters from the data I import. I have started to set something up where the string for a certain column must be be made of only there characters:

"ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz-" (note that there is a - besides just letters) and I may want to add some other characters later. So basically the script will drop or replace any character not found in my definitions with "", thus removing the illegal character and joining the previous and next characters.

I thought for sure there would be a script posted somewhere online that did this but I can't find it and my syntax skills are lacking.
