[ http://issues.apache.org/jira/browse/DERBY-166?page=all ]
Kristian Waagan closed DERBY-166. --------------------------------- > NULL is not a valid constraint type > ----------------------------------- > > Key: DERBY-166 > URL: http://issues.apache.org/jira/browse/DERBY-166 > Project: Derby > Issue Type: Bug > Components: Documentation > Affects Versions: 10.0.2.0 > Environment: Windows XP SP1 Professional > Reporter: George Baklarz > Priority: Trivial > > The following statement in the documentation is incorrect: > NULL The opposite of NOT NULL (not really a constraint), it specifies that > the column can hold NULL values. Specifying NULL is the same as saying > nothing at all, except when the column is included in a PRIMARY KEY > constraint. > If you try to create a column with the NULL attribute, you get a failure: > CREATE TABLE X ( A INT NULL ); > ERROR 42X01: Syntax error: Encountered "null" at line 1, column 23. > While this isn't really a problem since we can just omit the NULL keyword, > the documentation gives the impression that it is allowed in the CREATE > statement. -- 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
