Answer 1

if you want to find an existing delimier and split it

try this query :

select  substr(filed_name ,
               REGEXP_SUBSTR(filed_name,'#demilimer#',1),
               (REGEXP_SUBSTR(filed_name,'#demilimer#',2)-1)
    ) col1  ,  

  substr(filed_name ,
               REGEXP_SUBSTR(filed_name,'#demilimer#',2),
               REGEXP_SUBSTR(filed_name,'#demilimer#',3)- (REGEXP_SUBSTR(filed_name,'#demilimer#',2))
    ) col2  ,
     substr(filed_name ,
               REGEXP_SUBSTR(filed_name,'#demilimer#',3),
               length(filed_name)- (REGEXP_SUBSTR(filed_name,'#demilimer#',3))
    ) col3        /* last col should take up to the length  */

from table_name
