Hello,

I am trying to import to my Oracle DB (using SQL Developer 4.0.2.15) an Excel file with text columns in Hebrew, Using. But instead Hebrew word "בדיקה", I'm seeing in Oracle the following: "áãé÷ä".

Some details:

1) Oracle DB version (SELECT * FROM V$VERSION):

Oracle Database 12c Release 12.1.0.1.0 - 64bit Production
PL/SQL Release 12.1.0.1.0 - Production
"CORE 12.1.0.1.0 Production"
TNS for 64-bit Windows: Version 12.1.0.1.0 - Production
NLSRTL Version 12.1.0.1.0 - Production


2) DB computer OS - Windows 7 Professional, 64 bit.

3) Running this Select * From nls_database_parameters gives me:


NLS_NCHAR_CHARACTERSET	AL16UTF16
NLS_CHARACTERSET	AL32UTF8



Any suggestions of how to see the Hebrew in a proper way would be very appreciated.
Thanks in advance.

The first thing to know is: "have you Hebrew characters in your database or not?"
Post the result of:
select dump(col_with_hebrew_char) dmpval, asciistr(col_with_hebrew_char) ascstr
from mytable 
where rownum=1 and ...;

in order to have the content of a field with Hebrew characters.

My questions was about importing from Excel to Oracle. The Hebrew fields, imported via ODBC from Excel are not displayed correctly.
The Hebrew fields, which are in my Database now (like the one I pasted) - are displayed in a proper way.

Maybe I misunderstood you.

If I run the command on my imported from Excel Hebrew column:

Select HEBREW_COLUMN,
       Dump(HEBREW_COLUMN) dmpval, 
       Asciistr(HEBREW_COLUMN) ascstr
From TEST_TABLE


I'm getting this:

So the problem comes from the way you imported them from Excel as you didn't imported Hebrew characters but their replacement ones.
You say you did it via ODBC but how and what was the driver (editor/version) and what were the parameters of your ODBC DSN?

The ODBC driver I used - Microsoft Excel driver (*xls,*xlsx,*xlsm,*xlsb), version 14.00.7010.1000.

Creating the connection I made the following steps:

1) Using ODBC Microsoft Excel Setup dialog box, I created a system data source with name ODBC_IMPORT and chose there Version Excel 12.0.
2) I copied a file named 'inithsodbc.ora' in ORACLE_HOME\hs\admin, called it InitODBC_IMPORT.ora and substituted its content with this:

HS_FDS_CONNECT_INFO = ODBC_IMPORT
 HS_FDS_TRACE_LEVEL = 0


3) I added to the SID_LIST of the LISTENER.ORA file (in ORACLE_HOME\Network\admin) the following entry:

(SID_DESC=
(SID_NAME=ODBC_IMPORT)
(ORACLE_HOME=My ORACLE_HOME
(PROGRAM=hsodbc)
)
)

4) I added to the TNSNAMES.ORA file (in ORACLE_HOME\Network\admin) the following entry:


ODBC_IMPORT =
(DESCRIPTION=
(ADDRESS_LIST=
(ADDRESS=
(PROTOCOL=TCP)
(HOST=localhost)
(PORT=1521)
)
)
(CONNECT_DATA=(SID=ODBC_IMPORT))
(HS=OK)
)

5) Finally, I created a database link to the excel file with the following command:

Create Public Database Link ODBC_IMPORT_ANALYST
Connect to "home\tangt"
Identified by taktangspassword
Using 'ODBC_IMPORT';


This was a brief of a manual for creating ODBC connection from https://asktom.oracle.com Smile

In your Windows registry, what is the value for: HKLM\Software\Oracl`\<your Oracle home name>\NLS_LANG?
In the environment of the account which has imported the data, is there any NLS_LANG or NLS_CHARACTERSET set? (If it is your account check Computer\Properties\Advanced system Properties\Environment variables.)

I hope, I understood you right. I went to my Windows registry path HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\KEY_OraDB12Home1.
The value in NLS_LANG is AMERICAN_AMERICA.WE8MSWIN1252.

Should I change it to any other (Hebrew oriented)? If I change it, does it affect any other things in my computer?

Yes, it is my account on my work laptop. I checked Computer\Properties\Advanced system Settings\Advanced\Environment variables.
I don't see there any variables, named NLS_LANG or NLS_CHARACTERSET. Although, there is a variable named ORACLE_HOME.

This explains what you have. WE8MSWIN1252 does not support Hebrew characters so when you tried to import them they have been replaced by what Oracle calls a replacement character which is, if possible, the character the closest to the original one or, by default, a generic replacement character (which is ¿ in WE8MSWIN1252).

During the process of importing (and before starting your SQL*Plus that will load the Excel data) change this value to AMERICAN_AMERICA.AL16UTF16 (if this does work try AL32UTF8).

But first, do you see the Hebrew characters in your Excel sheet?

Yes, of course. In Excel I see Hebrew in a good way.
I don't use SQL*Plus. I'm working with SQL Developer. As I posted before, my DB has the following parameters:
NLS_NCHAR_CHARACTERSET	AL16UTF16
NLS_CHARACTERSET	AL32UTF8


I'll try them both.

Should I add any new Environment variables as well?

Here the important thing is to set the character set the client (program) will use, here SQL Developer.
I don't use it but modifying NLS_LANG in the registry before you launch SQL Developer should work.
As far as I remember, you can change SQL Developer encoding in Tools/Preferences/Environment box, try to use one of the UTF-16 or UTF-32 options.

I don't think you're really using SQL Developer - except to look at the data once you've already brought it in, correct?

SQL Developer is 100% Unicode compatible - most display issues in the tool come down to not using the right display FONT.

You should be able to skip all the ODBC link to Oracle stuff, and just have SQL Developer read your Excel file directly and import it in.

I changed the NLS_LANG registry value to AMERICAN_AMERICA.AL16UTF16 and restarted my SQL Developer.

Now I get a new error, while trying to import to Oracle from the same Excel file:
ORA-28545: Net8 אבחן שגיאה במהלך ההתחברות לסוכן

I don't remember that I changed any of ODBS parameters or tnsnames.ora or listener.ora.
Do you know - what may be the reason? It worked before.

I use SQL to take the raw data from our ERP databases, process it and build flat panels of data for my analysis tasks in the Oracle DB, that I created by myself. I am an analyst, "looking at data" as you say, and not a DBA at all.

I am trying to solve the issues by myself, because we have no DBA staff. Don't know what you mean by "skip all the ODBC link to Oracle stuff". If I understand right, the purpose of this forum is to help in such problems.

The reason may be in the character AL16UTF16 is not supported.
Try with UTF8.

Hi, I used this AMERICAN_AMERICA.AL32UTF8 for NLS_LANG registry value. It helped partially.

When I make a direct query from Excel file with SQL Developer:

Select *
From DATA$@ODBC_IMPORT_ANALYST;


I see Hebrew:

בדיקה


But if I insert the Hebrew values in Oracle table:

Insert into TEST_TABLE
Select *
From DATA$@ODBC_IMPORT_ANALYST;


I see it like this now:

힑힓힙힧힔



Maybe I should define some new Environment Variable or something?

By the way, what are your Windows code pages?
See registry key HKLM\SYSTEM\CurrentControlSet\Control\Nls\CodePage, values ACP and OEMCP.

This is the same problem, your query tool must have been configured to support Hebrew characters.
First see NLS_LANG when it was started. Fix it and restart the tool.

When I query Hebrew data from Excel:

Select *
From DATA$@ODBC_IMPORT_ANALYST;


I see it correctly:

בדיקה


When I query Hebrew data from another Oracle DB (from ERP) via database link:

Select Asciistr(ITEMS.LOCAL_NAME) as ACSII_ITEM_NAME, 
       ITEMS.LOCAL_NAME as ITEM_NAME
From ITEMS@ERP_ANALYST;


I see it incorrectly:

ACSII_ITEM_NAME	ITEM_NAME
\00F4\00F8\00E9\00E8 \00EC\00E1\00E9\00E8\00E5\00EC \00F2\00E9\00F1\00F7\00E0\00E5\00FA	ôøéè ìáéèåì òéñ÷àåú

I assume this is done with the same client and the same tool but it should be better you specify all of these in your posts.

Conversion occurs during transfer of data because database, the instance or client does not support the characters.
What is the character set of this latter database?
What was NLS_LANG value when the database was started?

Yes, all the queries I do with the same SQL Developer on my computer.

Now we are talking about external DB (Let's call him ERP DB), I use?
What queries should I run on it in order to give you the needed information?

When I query ERP DB:
Select * 
From nls_database_parameters


I get:

NLS_CHARACTERSET	WE8MSWIN1252
NLS_NCHAR_CHARACTERSET	AL16UTF16
