I have a column the contains address - street name and number. in hebrew.
When I select - the address retuned right but the number is reversed.
So - רח' ביאליק 23 Is actually רח' ביאליק 32
Τhe confusing part is that only the numbers reversed, the string itself stays the same
The column is VARCHAR2(56)
NLS_CHARACTERSET IW8ISO8859P8
Any Idea? Or how to get it right ?

Welcome to the forum.
Please read the OraFAQ Forum Guide and How to use [code] tags and make your code easier to read.
Indent the code, use code tags and align the columns in result.

Also always post your Oracle version, with 4 decimals (query v$version), as often solution depends on it.

Can you post the result of:

select dump(address) from table;

for this row

The easiest guess is that the data itself is incorrect - the number 32 was stored (instead of 23) by accident.

You seem to assume this is not the case. But, how would you know? If you select from the table, you see 32. How else (other than selecting from the table) would you know that the data in the table is correct, and only "selecting" it somehow changes it?

Are you able to replicate this - INSERT repeatedly with the number 23, then SELECT and see that it is shown as 32? Did you try something like that?

What Michel suggested will help figure this out; DUMP shows exactly what is stored in the database, byte by byte, and in order. For a question like this, using DUMP should always the first thing to try.
