Case Insensitve Search

I was wondering how I can do a case-insensitive search
if the string is something like, "2222ab".
If I typed in "%a" or "%A" (which is a search using a wildcard), it should return 2222ab.
Any advice anyone?

Convert "2222ab" and the search string to upper case and compare.
"2222ab".toUpperCase().indexOf(<Search String without the wild card>.toUpperCase()) > 0
Did i answer your question??

If you are looking for Database functions, you can convert both the search string and the compared string to uppercase(or lowercase):
"SELECT emp_name FROM emp WHERE UPPER(emp_desc) LIKE UPPER("%a%")
the above will return any employee that has an "a" or "A" in his description.

remember that if you do a function in the where clause on the indexed column, you will not get use of the index.
so hopefully your column is in all uppercase and you can just upper the user input, that way you can get the index
where emp_name like upper(u_name)

I agree. Here's the link:
