OracleLob.CopyTo Method (OracleLob)
Assembly: System.Data.OracleClient (in System.Data.OracleClient.dll)
If the destination offset is beyond the end of destination LOB, the LOB to which the data is being copied is extended. The space between the end of the LOB and the destination offset beyond the end is padded with zeros for BLOB data types and spaces for CLOB and NCLOB data types.
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.
In this release, a write operation to a read-only LOB might succeed, but not update the LOB on the server. In this case, however, the local copy of the LOB will be updated. Therefore, later read operations on the OracleLob object might return the results of the write operation.
The CopyTo method does not clear the contents of the destination OracleLob before performing the copy operation.
