Subject [jira] Commented: (DERBY-1520) Document new SYSCS_DIAG tables
Date Wed, 14 Feb 2007 04:40:05 GMT

    [ https://issues.apache.org/jira/browse/DERBY-1520?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12472979
] 

Daniel John Debrunner commented on DERBY-1520:
----------------------------------------------

A1) yes, though any strict definition should probably be avoided to allow future changes
A3) yes.
A4) I think either is fine, maybe diagnostic has a slight edge.

"You invoke this diagnostic table by specifing the table name in statement,"

sounds awkward to me. Tables are not "invoked", I think the term is left over from the previous
syntax
I think the key point to get across is that this is accessed like any other table.
