Hello. I created a table with a field name 'request_notes' of datatype varchar2(4000). The problem is sometimes the field exceeds 4000 and produces an errors. I would like to convert this field to a datatype which can hold a larger amount of data (ie. LONG, CLOB or BLOB). The field has valuable data in it which I don't want to loose. Please tell me how I can successfully make the conversion and maintain the data without losing or corrupting the data.
