[ http://nagoya.apache.org/jira/browse/DERBY-13?page=comments#action_57002 ] Shreyas Kaushik commented on DERBY-13: --------------------------------------
In response to Sateesh's comments: Should the behaviour for the two queries you mentioned in your example, be taken care of at the compile time or bind time ? I feel they should be probably under a seperate bug, shouldn't they ? As this is likely to have a much larger impact. For this bug it is how the from list behaves and the comparision that needs to go in here, as Dan has suggested used the getExposedTableName approach. > Quoted names with embedded period mishandled in from list > --------------------------------------------------------- > > Key: DERBY-13 > URL: http://nagoya.apache.org/jira/browse/DERBY-13 > Project: Derby > Type: Bug > Components: SQL > Versions: 10.0.2.0 > Reporter: Ramandeep Kaur > Priority: Minor > Attachments: Derby-13.patch > > Opening this bug on behalf of Satheesh Bandaram > --------------------------------------------------------- > 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. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://nagoya.apache.org/jira/secure/Administrators.jspa - If you want more information on JIRA, or have a bug to report see: http://www.atlassian.com/software/jira
