Knut Anders Hatlen updated DERBY-1443:
--------------------------------------
Attachment: javadoc.diff
Hi Steve,
I don't know what issue you were running into, but changing isBinaryType() to
return true for BLOB is not the correct solution. The attached patch adds
javadoc comments to isBinaryType() and isCharacterType() clarifying why they
don't return true for Types.BLOB and Types.CLOB. I have committed the patch
with revision 423827.
Here's the added javadoc for isBinaryType():
private static boolean isBinaryType(int jdbcType)
Check whether a JDBC type is compatible with the Java type byte[].
Note: BLOB is not compatible with byte[]. See tables B-4, B-5 and B-6 in
the JDBC 3.0 Specification.
Parameters:
jdbcType - a JDBC type
Returns:
true iff jdbcType is compatible with byte[]

> Surely BLOB is a binary type and so method should return true?
