As a result, each blob or clob field requires at least 2K of storage (depending on the database block size). Long raw datatypes are stored in-line, and are discouraged. For string data, the varchar2 type can be used for lengths up to 2000; the clob type can be used for longer field data. ( ** blob = binary large object, clob = character large object) The CLOB datatype requires the dbms_lob package. For example, see this procedure for storing an MS-Word document inside an Oracle row where the dbms_lob.instr procedure is used to search search inside the contents of the CLOB column: select dbms_lob.substr(clob_column,dbms_lob_instr(clob_column,'burleson'),1) from clob_tab where For some scenario the size of data in DBCLOB column is more than 32672 and, since we are converting DBCLOB to XML via VARCHAR, so the output get limited to 32672, and XML conversion fails.
