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

No you cannot. Reason is that UPPER and LOWER operate to the strings, so they do not take collection as argument.
