Bug 329092

Description Michael OBrien 2010-10-29 15:09:46 EDT

>The case is wrong in the following example
>The code as written will insert [NULL] as a value for the firstname named parameter

http://wiki.eclipse.org/Using_EclipseLink_JPA_Extensions_(ELUG)#Using_Named_Parameters_in_a_Native_Query

>following 
Query queryEmployees = entityManager.createNativeQuery(
    "SELECT * FROM EMPLOYEE emp WHERE emp.fname LIKE #firstname");
queryEmployees.setParameter("firstName", "Joan");
Collection employees = queryEmployees.getResultList();

>should be
Query queryEmployees = entityManager.createNativeQuery(
    "SELECT * FROM EMPLOYEE emp WHERE emp.fname LIKE #firstname");
queryEmployees.setParameter("firstname", "Joan");
Collection employees = queryEmployees.getResultList();

>non-trivial as the wiki documentation needs to be modified to either set the correct capitalization
>or set the upper case flag [useUpperCaseForComparisions] on the parameter


>The following bind parameter call will fail when the cases do not match for
aQuery = entityManager.createNativeQuery("select * from table where id = #anid....");
aQuery.setParameter("anId", 32); // force use of "anId" instead of "anid" to test case-sensitivity

>in the following [value] will be null
