King Netfix ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *updated* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiYWJmMTRhMGY4... ) / Bug ( https://hibernate.atlassian.net/browse/HHH-13989?atlOrigin=eyJpIjoiYWJmMT... ) HHH-13989 ( https://hibernate.atlassian.net/browse/HHH-13989?atlOrigin=eyJpIjoiYWJmMT... ) Hibernate cannot correctly recognize the property named "count" in HQL ( https://hibernate.atlassian.net/browse/HHH-13989?atlOrigin=eyJpIjoiYWJmMT... ) Change By: King Netfix ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) I have a Java entity managed by Hibernate as follows: { { code:java} @Entity public class Product { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) protected Integer id; @Column(name = "`count`") protected Integer count; // omit getters / setters for brevity } {code } I want to execute a HQL statement as follows: { { code:sql}-- HQL: update Product set count = 1 where id = 1 // -- executed by the following core code: // -- org.hibernate.Session session = getSession(); // -- session.createQuery("HQL").executeUpdate(); {code } } However it threw the following exception: {{ {quote} java.lang.ClassCastException: org.hibernate.hql.internal.ast.tree.SqlNode cannot be cast to org.hibernate.hql.internal.ast.tree.FromReferenceNode at org.hibernate.hql.internal.ast.HqlSqlWalker.generateSyntheticDotNodeForNonQualifiedPropertyRef(HqlSqlWalker.java:745) at org.hibernate.hql.internal.ast.HqlSqlWalker.lookupNonQualifiedProperty(HqlSqlWalker.java:738) at org.hibernate.hql.internal.antlr.HqlSqlBaseWalker.propertyRef(HqlSqlBaseWalker.java:1176) at org.hibernate.hql.internal.antlr.HqlSqlBaseWalker.assignment(HqlSqlBaseWalker.java:1061) at org.hibernate.hql.internal.antlr.HqlSqlBaseWalker.setClause(HqlSqlBaseWalker.java:777) at org.hibernate.hql.internal.antlr.HqlSqlBaseWalker.updateStatement(HqlSqlBaseWalker.java:393) at org.hibernate.hql.internal.antlr.HqlSqlBaseWalker.statement(HqlSqlBaseWalker.java:281) at org.hibernate.hql.internal.ast.QueryTranslatorImpl.analyze(QueryTranslatorImpl.java:272) at org.hibernate.hql.internal.ast.QueryTranslatorImpl.doCompile(QueryTranslatorImpl.java:192) at org.hibernate.hql.internal.ast.QueryTranslatorImpl.compile(QueryTranslatorImpl.java:144) at org.hibernate.engine.query.spi.HQLQueryPlan.<init>(HQLQueryPlan.java:113) at org.hibernate.engine.query.spi.HQLQueryPlan.<init>(HQLQueryPlan.java:73) at org.hibernate.engine.query.spi.QueryPlanCache.getHQLQueryPlan(QueryPlanCache.java:155) at org.hibernate.internal.AbstractSharedSessionContract.getQueryPlan(AbstractSharedSessionContract.java:604) at org.hibernate.internal.AbstractSharedSessionContract.createQuery(AbstractSharedSessionContract.java:716) at org.hibernate.internal.AbstractSharedSessionContract.createQuery(AbstractSharedSessionContract.java:113) at me.codeplayer.test.dao.TransactionTest.test(TransactionTest.java:35) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:50) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:12) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:47) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:17) at org.springframework.test.context.junit4.statements.RunBeforeTestExecutionCallbacks.evaluate(RunBeforeTestExecutionCallbacks.java:74) at org.springframework.test.context.junit4.statements.RunAfterTestExecutionCallbacks.evaluate(RunAfterTestExecutionCallbacks.java:84) at org.springframework.test.context.junit4.statements.RunBeforeTestMethodCallbacks.evaluate(RunBeforeTestMethodCallbacks.java:75) at org.springframework.test.context.junit4.statements.RunAfterTestMethodCallbacks.evaluate(RunAfterTestMethodCallbacks.java:86) at org.springframework.test.context.junit4.statements.SpringRepeat.evaluate(SpringRepeat.java:84) at org.junit.runners.ParentRunner.runLeaf(ParentRunner.java:325) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.runChild(SpringJUnit4ClassRunner.java:251) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.runChild(SpringJUnit4ClassRunner.java:97) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:290) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:71) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:288) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:58) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:268) at org.springframework.test.context.junit4.statements.RunBeforeTestClassCallbacks.evaluate(RunBeforeTestClassCallbacks.java:61) at org.springframework.test.context.junit4.statements.RunAfterTestClassCallbacks.evaluate(RunAfterTestClassCallbacks.java:70) at org.junit.runners.ParentRunner.run(ParentRunner.java:363) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.run(SpringJUnit4ClassRunner.java:190) at org.junit.runner.JUnitCore.run(JUnitCore.java:137) at com.intellij.junit4.JUnit4IdeaTestRunner.startRunnerWithArgs(JUnit4IdeaTestRunner.java:68) at com.intellij.rt.junit.IdeaTestRunner$Repeater.startRunnerWithArgs(IdeaTestRunner.java:33) at com.intellij.rt.junit.JUnitStarter.prepareStreamsAndStart(JUnitStarter.java:230) at com.intellij.rt.junit.JUnitStarter.main(JUnitStarter.java:58) {quote } } I could NOT understand the exception. I also want to work hard to find the error, , but to no avai. Finally I renamed the "count" property to "counter". It miraculously worked fine. Therefore, I suspect that Hibernate can NOT properly handle HQL containing reserved keywords such as "count". If I remember correctly, I have used this in previous versions, but it has no problem.
