Erases all data from this OracleLob.
Assembly: System.Data.OracleClient (in System.Data.OracleClient.dll)
Erase does not truncate data. The LOB length remains the same for a BLOB data type, and the erased data is replaced by 0x00. CLOB and NCLOB data types are replaced by spaces.
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 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.
