jpa case-insensitive in-clause for a list of string values

Question

I want to know if JPQL is capable of doing a case-insensitive search on a collection of string.

Scenario:

Table1:

Column1 (int)  | Column2(s         


        

Answer 1

You can always do :

from Table1 a where (upper(a.column2) = upper(:value1) 
    or upper(a.column2) = upper(:value2) 
    or ...)
