Question

How to search using wild card (in Oracle), without worrying about case or order in which the words appear.

e.g. if I search for like '%a%b%', it should return values containing *a*b*, *A*B* ,*b*a* and *B*A* This is just a sample, the search may have 5 or more words, is it possible get the result in just one expression rather than using AND.

Answer 1

select * 
from yourtable
where yourfield like '%a%'
and yourfield like '%b%'
