Jose Freire ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *created* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiN2MyYjU4OTQy... ) / Bug ( https://hibernate.atlassian.net/browse/HHH-16128?atlOrigin=eyJpIjoiN2MyYj... ) HHH-16128 ( https://hibernate.atlassian.net/browse/HHH-16128?atlOrigin=eyJpIjoiN2MyYj... ) Parameters out of order on inner join with entities with @Inheritance(strategy = InheritanceType.JOINED) ( https://hibernate.atlassian.net/browse/HHH-16128?atlOrigin=eyJpIjoiN2MyYj... ) Issue Type: Bug Affects Versions: 5.4.33, 5.6.14 Assignee: Unassigned Attachments: TestCase-ParametersOutOfOrder.tar.gz Components: hibernate-core Created: 01/Feb/2023 16:52 PM Environment: Hibernate 5.6.14.Final, SQL Server, Amazon Correto Priority: Major Reporter: Jose Freire ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) Having the following entities: @Entity @Inheritance(strategy = InheritanceType.JOINED) public class TestClassSuper implements Serializable { private static final long serialVersionUID = 1L; private Long id; private String text; private Date date; private BigDecimal number; .... } @Entity public class TestClassA extends TestClassSuper { private static final long serialVersionUID = 1L; private Long id; .... } @Entity public class TestClassB extends TestClassSuper { private static final long serialVersionUID = 1L; private Long id; .... } The following HQL: SELECT a.id FROM org.hibernate.bugs.testclassa a LEFT JOIN org.hibernate.bugs.testclassa c ON a.id = c.id AND c. date = : date LEFT JOIN org.hibernate.bugs.testclassb b ON a.id = b.id AND a. text = : text Produces the SQL: SELECT testclassa0_.id AS col_0_0_ FROM testclassa testclassa0_ INNER JOIN testclasssuper testclassa0_1_ ON testclassa0_.id = testclassa0_1_.id LEFT OUTER JOIN ( testclassa testclassa1_ INNER JOIN testclasssuper testclassa1_1_ ON testclassa1_.id = testclassa1_1_.id ) ON ( testclassa0_.id = testclassa1_.id AND testclassa1_1_. date = ? ) LEFT OUTER JOIN ( testclassb testclassb2_ INNER JOIN testclasssuper testclassb2_1_ ON testclassb2_.id = testclassb2_1_.id ) ON ( testclassa0_.id = testclassb2_.id AND testclassa0_1_. text = ? ) However, by changing the first LEFT JOIN to INNER JOIN in the HQL: SELECT a.id FROM org.hibernate.bugs.testclassa a INNER JOIN org.hibernate.bugs.testclassa c ON a.id = c.id AND c. date = : date LEFT JOIN org.hibernate.bugs.testclassb b ON a.id = b.id AND a. text = : text Produces the SQL: SELECT testclassa0_.id AS col_0_0_ FROM testclassa testclassa0_ INNER JOIN testclasssuper testclassa0_1_ ON testclassa0_.id = testclassa0_1_.id INNER JOIN testclassa testclassa1_ ON 1 = 1 INNER JOIN testclasssuper testclassa1_1_ ON testclassa1_.id = testclassa1_1_.id LEFT OUTER JOIN ( testclassb testclassb2_ INNER JOIN testclasssuper testclassb2_1_ ON testclassb2_.id = testclassb2_1_.id ) ON ( testclassa0_.id = testclassb2_.id AND testclassa0_1_. text = ? ) WHERE ( testclassa0_.id = testclassa1_.id AND testclassa1_1_. date = ? ) The parameter sequence has changed! In the first query the parameter sequence in the query is: date, text. In the second query the parameter sequence in the query is: text, date. But the binding order for the second query is the same as the first query, thus the cast exception on SQL Server: Caused by: com.microsoft.sqlserver.jdbc.SQLServerException: Conversion failed when converting date and/or time from character string. at com.microsoft.sqlserver.jdbc.SQLServerException.makeFromDatabaseError(SQLServerException.java:265) at com.microsoft.sqlserver.jdbc.SQLServerResultSet$FetchBuffer.nextRow(SQLServerResultSet.java:5479) at com.microsoft.sqlserver.jdbc.SQLServerResultSet.fetchBufferNext(SQLServerResultSet.java:1798) at com.microsoft.sqlserver.jdbc.SQLServerResultSet.next(SQLServerResultSet.java:1056) at org.hibernate.loader.Loader.getRowsFromResultSet(Loader.java:1043) at org.hibernate.loader.Loader.processResultSet(Loader.java:998) at org.hibernate.loader.Loader.doQuery(Loader.java:967) at org.hibernate.loader.Loader.doQueryAndInitializeNonLazyCollections(Loader.java:357) at org.hibernate.loader.Loader.doList(Loader.java:2868) Hibernate is binding the parameter of type ‘date’ into the binding position ‘0', but the ‘date’ parameter position has changed to the binding position '1’. Attached is a test case, however I couldn’t reproduce with H2 database. My guess is that H2 doesn’t care, because the generated SQL is identical.
