Ketan,

CONTAINS() is an Intermedia operator and will blow an error if no Intermedia index exists on the column that is indexed. 

Rodd, unfortunately I think you'll have to resort to PL/SQL.  You'd have to split the LONG field into the 32K varchar2 chunk and substr() it. We are making the (possibly wrong) assumption that any view definition is less than 32K long.  Metalink goes on to say that you can manipulate the full length of a long via JDBC (note 123009.1) and Pro*C (1007848.6).  I claim ignorance on both

I know this isn't good news and it's possible that others on the list have a better idea.

Hi,
For long data type in selection use "contains" instead of like. Before this set environment for sql*plus like "  set long 5000 ".
