Subject [jira] Created: (DERBY-1516) Inconsistent behavior for getBytes and getSubString for embedded versus network
Date Sun, 16 Jul 2006 20:10:13 GMT
Inconsistent behavior for getBytes and getSubString for embedded versus network
-------------------------------------------------------------------------------

                 Key: DERBY-1516
                 URL: http://issues.apache.org/jira/browse/DERBY-1516
             Project: Derby
          Issue Type: Bug
            Reporter: Craig Russell
            Priority: Minor


org.apache.derby.client.am.Clob.getSubString(pos, length) and org.apache.derby.client.am.Blob.getBytes(pos,
length) check the length for less than zero. 

            if ((pos <= 0) || (length < 0)) {
                throw new SqlException(agent_.logWriter_, "Invalid position " + pos + " or
length " + length);

But org.apache.derby.impl.jdbc.EmbedClob(pos, length) and org.apache.derby.impl.jdbc.EmbedBlob(pos,
length) check the length for less than or equal to zero.

       if (length <= 0)
            throw Util.generateCsSQLException(
                SQLState.BLOB_NONPOSITIVE_LENGTH, new Integer(length));

The specification does not disallow length of zero, so zero length should be allowed. I believe
that the implementation in org.apache.derby.client.am is correct, and the implementation in
org.apache.derby.impl.jdbc is incorrect.
