Subject [jira] Updated: (DERBY-1255) Implement new JDBC4 methods for creating empty LOBs in the embedded client
Date Wed, 17 May 2006 15:12:07 GMT
     [ http://issues.apache.org/jira/browse/DERBY-1255?page=all ]

V.Narayanan updated DERBY-1255:
-------------------------------

    Attachment: ClobBlob_create_v1.diff
                ClobBlob_create_v1.stat

Implementing createClob() and createBlob() Methods on the Embedded Server

To implement these methods two new constructors have been introduced in
EmbedClob and EmbedBlob having the following signatures

EmbedClob(String clobString,EmbedConnection con)
EmbedBlob(byte [] blobBytes,EmbedConnection con)

The set methods in the LOB (JDBC3 methods) are not implemented on the Embedded side. 
So the tests basically ensure that the length of the newly created objects in zero
(i.e.) ensure that they are empty initially.

ConnectionTest.java was failing because createQueryObject in
BrokeredConnection40 needed to be forwarded to EmbedConnection40 (i.e.) the
underlying connection that it wraps. I have fixed that up as part of this patch.

thanx
Narayanan
