Subject [jira] Updated: (DERBY-331) create table fails when a constraint defintion follows a column default
Date Fri, 10 Jun 2005 18:47:46 GMT
     [ http://issues.apache.org/jira/browse/DERBY-331?page=all ]

Dag H. Wanvik updated DERBY-331:
--------------------------------

    Attachment: 331.stat
                331.diff

This patch fixes a look-ahead problem in the parser: In the method DB2DefaultOption, 
the look-ahead for  miscBuiltins is too liberal: it mistakenly thinks it has found a
builtin in this case. I made the look-ahead more specific by adding a check against comma.
 I have extended the test lang/columnDefaults.sql with this case.
I have run derbyall with no errors.
