Herman Vierendeels created OPENJPA-2286:
-------------------------------------------
Summary: SELECT COUNT with date litteral,used more than once,
provokes ArgumentException: Attempt to compare incompatible types class
java.util.Date and class org.apache.openjpa.jdbc.sql.Raw
Key: OPENJPA-2286
URL: https://issues.apache.org/jira/browse/OPENJPA-2286
Project: OpenJPA
Issue Type: Bug
Components: query
Affects Versions: 2.2.0
Environment: tested with
openjpa-all-2.2.0.jar
openjpa-all-2.3.0-20121019.065014-74.jar
org.apache.derby.jdbc.ClientDriver
com.ibm.as400.access.AS400JDBCDriver
Reporter: Herman Vierendeels
Fix For: 2.3.0
a select count with date literal throws exception if used more than once in
EntityManagerFactory
SELECT COUNT(x) FROM TestCountWithDate x WHERE LOWER(x.name) LIKE '%vier%' AND
x.adate = {d '2007-12-12'}
INFO: qry_0=SELECT COUNT(x) FROM TestCountWithDate x WHERE LOWER(x.name) LIKE
'%vier%' AND x.adate = {d '2007-12-12'}
Exception in thread "main" <openjpa-2.2.0-r422266:1244990 nonfatal user error>
org.apache.openjpa.persistence.ArgumentException: Attempt to compare
incompatible types "class java.util.Date" and "class
