    column name referred to in that function/procedure.

  1. Dear Shahid,

    The post is really very informative. As per my work experience, I found that in most of the cases 'ORA -600' error occurs because of file corruption. Oracle inbuilt utility RMAN help in this case. But when oracle database inbuilt utility get failed to repair corrupt file then third party Oracle database recovery helps users to repair corrupt file. Stellar Phoenix Oracle Database Recovery Software is one of the best tool!!
