Rick Hillegas updated DERBY-565: -------------------------------- Version: 10.1.1.0 Update "affects version" field. > Misleading parser diagnostics > ----------------------------- > > Key: DERBY-565 > URL: http://issues.apache.org/jira/browse/DERBY-565 > Project: Derby > Type: Bug > Components: SQL > Versions: 10.1.1.0 > Reporter: Rick Hillegas > Priority: Minor > > Bryan Pendleton reports: > When I mistype 'join' as 'joing', the error message that I > get actually complains about the word 'left'. It ought to, > in my opinion, complain about the word 'joing', since that > is truly the word with the syntax error in it. > ij> select * from t1 left outer joing t2 on t1.c2=t2.c1; > ERROR 42X01: Syntax error: Encountered "left" at line 1, column 18. > I don't know if this is a PITA to fix or not, but I thought > I'd send it along anyway since it was so easy to reproduce. > ------------------------------------------------------- > This appears to be a problem with hand-coded lookahead logic. Although fixing > this particular lookahead issue might be trivial, this is part of a larger > problem since the parser is liberally peppered with similar hand-coded > lookahead logic. Coming up with a general solution might involve some > creativity. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
