String search in multiple columns of a table

856037May 8 2012 — edited May 8 2012

Hi,

I have a requirement in which i want to search a particular string say 'ABC' in columns col1,col2,col3 of table tab1. If the string is there in either of these columns i need to pick up that row.
Currently i am using 'INSTR' ,'OR' clauses to achieve this.
But it is taking long time to execute.
Can anybody suggest me an alternative for this which will give me better execution time.
