Hello!
In my Database, this SQL is error:
select * from tablename;
it will cause a Table unknow error;
This is all right:
select * from "tablename";

The same thing is happened in column name;
I have to double quote every table name & column name in my SQL.

My Enviroment:
Firebird1.5 RC2 / Windows 2000.
The database is created by EMS Interbase&Firebird Manager 3.

What's the reason, and how to correct it?

Thanks.
