Assembly: System.Data.OracleClient (in system.data.oracleclient.dll)
To write to the LOB, you must have retrieved the LOB using the FOR UPDATE clause in the SQL SELECT statement, and you must have a local transaction started.
All data from the source LOB is appended to the end of the current LOB. The position of neither LOB is evaluated or changed during this process.
The underlying data types must always be the same. For example, if you are appending from an NClob, the destination OracleLob must also be an NClob.
In this release, a write operation to a read-only LOB might succeed, but does not update the LOB on the server. In this case, however, the local copy of the LOB is updated. Therefore, later read operations on the OracleLob object might return the results of the write operation.
