Subject [jira] [Commented] (DERBY-5506) Document that EXISTS subquery can now select more then one column
Date Fri, 18 Nov 2011 22:06:52 GMT

    [ https://issues.apache.org/jira/browse/DERBY-5506?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13153167#comment-13153167
] 

Kim Haase commented on DERBY-5506:
----------------------------------

It appears that the only change that would be required would be to remove the following sentence
from the TableSubquery topic in the Reference Manual:

"When used with EXISTS, it returns multiple columns only if you use * to return the multiple
columns."

It might be helpful, though, to add an example of the use of EXISTS without an asterisk.
