PL/SQL encoding issue

Eleftherios BampaletakisOct 5 2017 — edited Oct 6 2017

Hi all,

I searched through te blog and I could not find a solution for this issue, although it might be a FAQ. I am from Greece, so my database includes many greek characters. When i query

to get the results I am getting '????' as a result. I changed many times the nls_lang at my registry, but nothing helped.

The reuslts of the query SELECT * FROM V$NLS_PARAMETERS; are the following:

"PARAMETER","VALUE"

"NLS_LANGUAGE","AMERICAN"

"NLS_TERRITORY","AMERICA"

"NLS_CURRENCY","$"

"NLS_ISO_CURRENCY","AMERICA"

"NLS_NUMERIC_CHARACTERS",".,"

"NLS_CALENDAR","GREGORIAN"

"NLS_DATE_FORMAT","DD-MON-RR"

"NLS_DATE_LANGUAGE","AMERICAN"

"NLS_CHARACTERSET","EL8ISO8859P7"

"NLS_SORT","BINARY"

"NLS_TIME_FORMAT","HH.MI.SSXFF AM"

"NLS_TIMESTAMP_FORMAT","DD-MON-RR HH.MI.SSXFF AM"

"NLS_TIME_TZ_FORMAT","HH.MI.SSXFF AM TZR"

"NLS_TIMESTAMP_TZ_FORMAT","DD-MON-RR HH.MI.SSXFF AM TZR"

"NLS_DUAL_CURRENCY","$"

"NLS_NCHAR_CHARACTERSET","AL16UTF16"

"NLS_COMP","BINARY"

"NLS_LENGTH_SEMANTICS","BYTE"

"NLS_NCHAR_CONV_EXCP","FALSE"

My current NLS_LANG is American_America.EL8MSWIN1253 I have tried and the GREEK_GREECE.EL8MSWIN1253 but didn't work.

The database is oracle 11g and the client is pl/sql developer version is 12.04. The toad is working, but I prefer to use pl/sql developer.

At region and language at format tab I have English, at location tab I have Greece and for non unicode programs I have Greek.

Thanks in advance
