Subject [jira] Commented: (DERBY-13) Quoted names with embedded period mishandled in from list
Date Tue, 28 Dec 2004 11:20:04 GMT
     [ http://nagoya.apache.org/jira/browse/DERBY-13?page=comments#action_57083 ]
     
Jan Hlavatý commented on DERBY-13:
----------------------------------

Maybe the table names could be converted to canonical form before being used/compared?
After all, s1.t1 is just an easy way to write "S1"."T1", and should be threated as such.

> The compiler mishandles quoted names with embedded periods when 
> checking uniqueness of table names in the from list of a 
> SELECT. Consider the following SQL:
>   create table "S1.T1" (id int not null primary key, d1 int);
>   create schema s1;
>   create table s1.t1 (id int not null primary key, d2 int);
>   select * from s1.t1, "S1.T1" where s1.t1.id = "S1.T1".id;
> Derby throws an error on the final SELECT statement:
> "ERROR 42X09: The table or alias name 'S1.T1' is used more than 
> once in the FROM list". However s1.t1 and "S1.T1" are different 
> tables.
