Text description of to_clob

Purpose

TO_CLOB converts NCLOB values in a LOB column or other character strings to CLOB values. char can be any of the datatypes CHAR, VARCHAR2, NCHAR, NVARCHAR2, CLOB, or NCLOB. Oracle executes this function by converting the underlying LOB data from the national character set to the database character set.

The following statement converts NCLOB data from the sample pm.print_media table to CLOB and inserts it into a CLOB column, replacing existing data in that column.

UPDATE PRINT_MEDIA 
   SET AD_FINALTEXT = TO_CLOB (AD_FLTEXTN);
