Rick Hillegas updated DERBY-6000:
---------------------------------
Attachment: derby-6000-06-aa-DatabaseMetaData.diff
Attaching derby-6000-06-aa-DatabaseMetaData.diff. This patch makes the JDBC 4.2
changes to DatabaseMetaData. I will run regression tests.
This patch makes the following changes to the embedded and client drivers:
1) Changes the datatype of the CARDINALITY and PAGES columns returned by
getIndexInfo(). The column types are changed from INT to BIGINT.
2) Adds a getMaxLogicalLOBSize() method. This method is supposed to return the
maximum size of a LOB in bytes. For Derby that is the maximum size of a CLOB. A
CLOB can have Integer.MAX_VALUE chars, which works out to Integer.MAX_VALUE * 2
bytes.
3) Adds a supportsRefCursors() method. This returns false because Derby does
not support the Types.REF_CURSOR type.

> Open JDK 8 will include maintenance rev 4.2 of JDBC. The public discussion of
> JDBC 4.2 will take place here: http://openjdk.java.net/jeps/170. We will want
> to build Derby support for JDBC 4.2 after a public spec appears. At this
> time, it is unclear what Derby release will carry this support.
