Unicode : cannot filter query with NVARCHAR2 column

Question

Hi,
this is not a POL/SQL-Developer specific problem - but help would be appreciated.
Configuration Server :
NLS_CHARACTERSET WE8ISO8859P15
NLS_NCHAR_CHARACTERSET AL16UTF16
Client :
NLS_LANG GERMAN_GERMANY.WE8MSWIN1252
Column definition :
LEGALNAME NVARCHAR2 (255);
If i store for example a kyrillic name with the application i am able to finde the row searching the for the most current modification date and with correct kyrillic coded name.
but if i want to query by the Legalname - a)/b) does not work;
A) SELECT * FROM COMPANY WHERE LEGALNAME LIKE 'View, системой%';
B) SELECT * FROM COMPANY WHERE LEGALNAME LIKE N'View, системой%';
Do you have some hints???
kind regards
Karl

Hello Sergiusz,
first thanks a lot for your taking time!!
it did not work for PL/SQL-Developer (applied both registry - all oracle homes and in environment)
but it worked for Oracle SQL-Developer according your last posting;
[m-1951097]
bq. {color:#808080}By default, SQL Developer uses the JDBC Thin driver. This driver does not recognize the ORA_NCHAR_LITERAL_REPLACE, but the oracle.jdbc.convertNcharLiterals property. Try to add this property to the <SQLDEV_HOME>\sqldeveloper\bin\sqldeveloper.conf file: \\ AddVMOption -Doracle.jdbc.convertNcharLiterals=true \\ Let us know if it helps. I have no time to test myself. \\ {color} \\ {color:#808080} \\ Sergiusz{color}
