Oracle REGEXP_LIKE

Question

Could someone please help me with the Oracle query to search text appended with any non-alphabet character Or Space Eg:- INDIA- INDIA, INDIA -INDIA,INDIA INDIA

The query which I wrote to search INDIA retrieved rows with "INDIAA" as well.

SELECT *
FROM TABLE_NAME
WHERE (REGEXP_LIKE (COLUMN_NAME,'INDIA[,_)("-]') 
     OR REGEXP_LIKE (COLUMN_NAME,'[,_)("-]INDIA')
     OR REGEXP_LIKE (COLUMN_NAME,'[,_)("-]INDIA[,_)("-]')
     OR  REGEXP_LIKE (COLUMN_NAME,'\sINDIA\s')
     OR  REGEXP_LIKE (COLUMN_NAME,'\sINDIA') 
     OR REGEXP_LIKE (COLUMN_NAME, 'INDIA\s') -- this line is causing problem
     OR REGEXP_LIKE (COLUMN_NAME, '^INDIA$'))

Thank You!

Answer 1

I would suggest:

regexp_like(column_name, '(^|\W)INDIA(\W|$)')

This searches for 'INDIA' , surrounded by non-word characters ( \W ), or at the beginning or end of the string.
