[jira] Commented: (DERBY-946) Miscellaneous DatabaseMetaData methods added by JDBC 4

["Rick Hillegas (JIRA)" <de...@db.apache.org>]

    [ http://issues.apache.org/jira/browse/DERBY-946?page=comments#action_12375385 ] 

Rick Hillegas commented on DERBY-946:
-------------------------------------

In addition to the new columns in getProcedures() and getProcedureColumns() (addressed by DERBY-925), this spec change clarifies the behavior of getTypeInfo(), getCrossReference(), and getColumns(). These clarifications do not create extra work for us, for the following reasons:

o getTypeIno() - This clarification only affects databases which implement SQL DISTINCT and STRUCT types. Derby does not implement these.

o getCrossReference() - Derby implements the specified behavior for foreign key metadata.

o getColumns() - Derby implements the correct metadatga behavior for String DEFAULTs.
