Does the dialect support propagating changes to LOB values back to the database? Talking about mutating the internal value of the locator as opposed to supplying a new locator instance... For BLOBs, the internal value might be changed by:Blob.setBinaryStream(long)
,Blob.setBytes(long, byte[])
,Blob.setBytes(long, byte[], int, int)
, orBlob.truncate(long)
. For CLOBs, the internal value might be changed by:Clob.setAsciiStream(long)

,Clob.setString(long, String)
,Clob.setString(long, String, int, int)
, orClob.truncate(long)

will use the returnedSQLExceptionConversionDelegate
in addition to the following standard delegates:- a "static" delegate based on the JDBC 4 defined SQLException hierarchy;
- a delegate that interprets SQLState codes for either X/Open or SQL-2003 codes, depending on java.sql.DatabaseMetaData#getSQLStateType
