I’ve got a SQLQuery that I’ve moved to NativeQuery, and am now getting the error: jakarta.persistence.PersistenceException: Converting `org.hibernate.exception.SQLGrammarException` to JPA `PersistenceException` : Unable to find column position by name: title4_0_0_ at org.hibernate.internal.ExceptionConverterImpl.convert(ExceptionConverterImpl.java:165) at org.hibernate.query.spi.AbstractSelectionQuery.list(AbstractSelectionQuery.java:374) at org.hibernate.bugs.H2HibernateTest.testNativeQueryWithEntity(H2HibernateTest.java:83) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:77) at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.base/java.lang.reflect.Method.invoke(Method.java:568) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:59) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:12) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:56) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:17) at org.junit.internal.runners.statements.RunBefores.evaluate(RunBefores.java:26) at org.junit.internal.runners.statements.RunAfters.evaluate(RunAfters.java:27) at org.junit.runners.ParentRunner$3.evaluate(ParentRunner.java:306) at org.junit.runners.BlockJUnit4ClassRunner$1.evaluate(BlockJUnit4ClassRunner.java:100) at org.junit.runners.ParentRunner.runLeaf(ParentRunner.java:366) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:103) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:63) at org.junit.runners.ParentRunner$4.run(ParentRunner.java:331) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:79) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:329) at org.junit.runners.ParentRunner.access$100(ParentRunner.java:66) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:293) at org.junit.internal.runners.statements.RunBefores.evaluate(RunBefores.java:26) at org.junit.internal.runners.statements.RunAfters.evaluate(RunAfters.java:27) at org.junit.runners.ParentRunner$3.evaluate(ParentRunner.java:306) at org.junit.runners.ParentRunner.run(ParentRunner.java:413) at org.junit.runner.JUnitCore.run(JUnitCore.java:137) at com.intellij.junit4.JUnit4IdeaTestRunner.startRunnerWithArgs(JUnit4IdeaTestRunner.java:69) at com.intellij.rt.junit.IdeaTestRunner$Repeater$1.execute(IdeaTestRunner.java:38) at com.intellij.rt.execution.junit.TestsRepeater.repeat(TestsRepeater.java:11) at com.intellij.rt.junit.IdeaTestRunner$Repeater.startRunnerWithArgs(IdeaTestRunner.java:35) at com.intellij.rt.junit.JUnitStarter.prepareStreamsAndStart(JUnitStarter.java:235) at com.intellij.rt.junit.JUnitStarter.main(JUnitStarter.java:54) Caused by: org.hibernate.exception.SQLGrammarException: Unable to find column position by name: title4_0_0_ at org.hibernate.exception.internal.SQLExceptionTypeDelegate.convert(SQLExceptionTypeDelegate.java:64) at org.hibernate.exception.internal.StandardSQLExceptionConverter.convert(StandardSQLExceptionConverter.java:56) at org.hibernate.engine.jdbc.spi.SqlExceptionHelper.convert(SqlExceptionHelper.java:109) at org.hibernate.engine.jdbc.spi.SqlExceptionHelper.convert(SqlExceptionHelper.java:95) at org.hibernate.sql.results.jdbc.internal.AbstractResultSetAccess.resolveColumnPosition(AbstractResultSetAccess.java:67) at org.hibernate.query.results.dynamic.DynamicFetchBuilderStandard.lambda$buildFetch$0(DynamicFetchBuilderStandard.java:94) at org.hibernate.query.results.DomainResultCreationStateImpl.resolveSqlExpression(DomainResultCreationStateImpl.java:266) at org.hibernate.query.results.dynamic.DynamicFetchBuilderStandard.lambda$buildFetch$1(DynamicFetchBuilderStandard.java:91) at org.hibernate.metamodel.mapping.internal.BasicAttributeMapping.forEachSelectable(BasicAttributeMapping.java:363) at org.hibernate.metamodel.mapping.ModelPart.forEachSelectable(ModelPart.java:93) at org.hibernate.query.results.dynamic.DynamicFetchBuilderStandard.buildFetch(DynamicFetchBuilderStandard.java:108) at org.hibernate.query.results.DomainResultCreationStateImpl.lambda$visitFetches$2(DomainResultCreationStateImpl.java:408) The query is: NativeQuery query = session.createNativeQuery( "select /* findExampleBooks */ {book.*} from zbook_t book" ); The sql output by hibernate is below. Note the duplicated zpublish_3_0_0_: select /* findExampleBooks */ book.ZBOOK_PK zbook_pk1_0_0_, book.DESCRIPTION descript2_0_0_, book.ZPUBLISHER_FK zpublish3_0_0_, book.TITLE zpublish3_0_0_ from zbook_t book This appears to be due to the fact that we map the same column twice: @ManyToOne(targetEntity = ZPublisher.class, fetch = FetchType.LAZY) @JoinColumn(name = "ZPUBLISHER_FK" ) private ZPublisher publisher; @Column(name = "ZPUBLISHER_FK" , nullable = false , insertable = false , updatable = false ) @Access(AccessType.FIELD) private Long publisherFk; If I either remove foreign key mappings, or remove the braces in the sql, which expands the attributes, then the problem goes away. I only understood that it was due to the braces expansion as I was writing this up. In our case, I think we can just remove the braces in the sql, since we only return one entity in the cases where we map the results to an entity.
