See below for a working SQL script to be used by
isql -e -i greek.sql

As possibly the greek characters get disturbed
on the way to you, I also appended an uuencoded
version of the script.

It all assumes that your Linux box (or X11, or
whatever is responsible in your environemnt) is
configured to ISO-8859-7

*** begin of script

set names ISO-8859-7;
create database '/greek-test.fdb' user 'sysdba' password 'masterkey';
create table t1 (
c1 smallint not null primary key,
c2 varchar(64) character set WIN1253 collate PXW_GREEK
);

commit;

insert into t1 values (1, 'ABC');
insert into t1 values (2, 'DEF');
insert into t1 values (3, 'ÁíáëõôéêÝò ðëçñïöïñßåò ãéá ôçí ðïëéôéêÞ,');
insert into t1 values (4, 'ôç íïìïèåóßá êáé ôá ðñïãñÜììáôá ôçò');
insert into t1 values (5, 'ÅõñùðáúêÞò Åíùóçò ó÷åôéêÜ ìå ôïí ôïõñéóìü');
insert into t1 values (6, 'ìðïñåßôå íá âñåßôå óôïí êüìâï ôçò Å.Å., óôçí');
insert into t1 values (7, 'äéåýèõíóç: http://europa.eu.int/index_el.htm');
insert into t1 values (8, 'êáé óôïí êüìâï ôïõ ãñáöåßïõ ôçò ÅõñùðáúêÞò');
insert into t1 values (9, 'ÅðéôñïðÞò óôçí ÅëëÜäá, óôçí äéåýèõíóç:
http://www.ee.gr');

commit;

select * from t1;
