Case insensitive JPQL

There is no case insensitive comparison in SQL.
Thus, to write a case insensitive SQL, we have to first change the both parameter and value to same case.

The same concept is apply to JPQL as well.

below is the example of case insensitive JPQL.

String caseInsensitiveJPQL = " SELECT a FROM ENTITY a "

caseInsensitiveJPQL += " WHERE UPPER(a.PARAM1) = '" + value1.toUpperCase() "' ";

in the above example, I convert both PARAM1 and value1 to upper case.


Done!!
