How Do I Search CLOB Field in Oracle?
A "CLOB," or Character Large Object, field data type in Oracle is a large field that allows you to contain up to 8 terabytes of information. You cannot search a CLOB by default, but you can convert the CLOB to a character data type in your procedure to search in the CLOB's data. Searching CLOBs is a slow process, so you should only use this feature in tables that require you to search within the large CLOB data field.
