[Hibernate-JIRA] Created: (HHH-2261) Setting hibernate.hbm2ddl.auto=validate causes problems on mySQL with numeric fields

by Christian Sprajc (JIRA)

Setting hibernate.hbm2ddl.auto=validate causes problems on mySQL with numeric fields ------------------------------------------------------------------------------------ Key: HHH-2261 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2261 Project: Hibernate3 Type: Bug Components: core Versions: 3.2.1 Reporter: Christian Sprajc Hello, We got a Problem when using the following setup: 1) JBoss 4.0.4A with Hibernate 3.2.0 / mySQl 4.x AND 5.x 2) Set hibernate.hbm2ddl.auto=validate 3) Using a usertype which uses the SQL type: Types.NUMERIC When deploying our application I got the following error: 12:43:21,985 INFO [TableMetadata] columns: [paymenttype, amount, oid, remarks, currency, ae_date] 12:43:21,985 WARN [ServiceController] Problem starting service persistence.units:jar=com.riege.pogo_0.1.4.jar,unitName=PogoEntityManager org.hibernate.HibernateException: Wrong column type: amount, expected: numeric(19,2) at org.hibernate.mapping.Table.validateColumns(Table.java:251) at org.hibernate.cfg.Configuration.validateSchema(Configuration.java:1002) The Problem is: 1) When hibernate creates (e.g. hibernate.hbm2ddl.auto=update) through the columns in the mySQL database it creates it as "numeric(x,y)" field. 2) mySQL always converts "numeric(x,y)" to "decimal(x,y)". The metadata returns "decimal(x,y)" 3) When deploying with "hibernate.hbm2ddl.auto=validate" to error above is thrown. The problem is that hibernate expects a "numeric(x,y)" type but mysql returns a "decimal(x,y)" A workaround I'm now using is a fixed mySQL dialect which correctly handles Types.DECIMAL / "decimal(x,y)": public class FixedMySQLDialect extends org.hibernate.dialect.MySQLDialect { public FixedMySQLDialect() { super(); registerColumnType(Types.NUMERIC, "decimal(19, $l)"); registerColumnType(Types.DECIMAL, "decimal(19, $l)"); } } -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira

ClobType.setToXMLNode: could not read XML from Clob --------------------------------------------------- Key: HHH-2089 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2089 Project: Hibernate3 Type: Patch Components: core Versions: 3.2.0.cr4 Environment: Hib 3.2.0cr4, database: any Reporter: Pietro Iglio I get "org.hibernate.HibernateException: could not read XML from Clob" trying to retrieve a CLOB column as XML. I think I have found the reason of the bug in org.hibernate.type.ClobType: public void setToXMLNode(Node node, Object value, SessionFactoryImplementor factory) { ... node.setText( clob.getSubString(0, len) ); ... } According to the JDBC spec, the first character of Clob is at 1 position, so the correct line should be node.setText( clob.getSubString(1, len) ); -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira

[Hibernate-JIRA] Created: (HBX-730) SchemaExport with hibernate.hbm2ddl.auto does not create database schemas before it creates tables (fails with invalid schema name: on HSQLDB)

by Andrew Thompson (JIRA)

SchemaExport with hibernate.hbm2ddl.auto does not create database schemas before it creates tables (fails with invalid schema name: on HSQLDB) ----------------------------------------------------------------------------------------------------------------------------------------------- Key: HBX-730 URL: http://opensource.atlassian.com/projects/hibernate/browse/HBX-730 Project: Hibernate Tools Type: Improvement Environment: Hibernate 3.0.5, HSQLDB 1.8 I've also read the code in the SchemaExport, Table and Configuration classes in 3.2rc3 and it looks like this hasn't been added in 3.1 or 3.2. Reporter: Andrew Thompson I'm writing a unit test that creates the database it will work with using hibernate.hbm2ddl.auto=create-drop. This all works fine, so long as I don't use schemas in my .hbm.xml: <class name="com.example.Foo" table="foo_table"> If I add a schema like this, then the database creation fails on HSQLDB 1.8: <class name="com.example.Foo" schema="bar" table="foo_table"> Unsuccessful: create table bar.foo_table ( ... column names ... ) hbm2ddl.SchemaExport - invalid schema name: BAR in statement [create table bar.foo_table] As far as I know there is no way to ask Hibernate to create the schema before it tries to create the tables. There is a forum thread here that shows I am not the only one with this issue: http://forum.hibernate.org/viewtopic.php?p=2316411&sid=c0cd248a87bfb8d684... As this is a unit test, precreating the schema in the test code is plausible, but not particularly attractive. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira

[Hibernate-JIRA] Created: (HHH-2314) EntityUpdateAction does not do a deepCopy for loadedState, making change detection of Custom Type based on a Collection not working

by arnaud.roger＠gmail.com (JIRA)

EntityUpdateAction does not do a deepCopy for loadedState, making change detection of Custom Type based on a Collection not working ----------------------------------------------------------------------------------------------------------------------------------- Key: HHH-2314 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2314 Project: Hibernate3 Type: Bug Components: core Versions: 3.2.0.ga, 3.2.1 Environment: Hibernate 3.2.1.ga, SQLServer and Oracle 10 Reporter: arnaud.roger(a)gmail.com We have a User object with a roles HashSet<String> that is map with a CustomType to VARCHAR in the database using a comma separated format. When this Entity is manipulated through a long transaction hibernate does not detect that the Entity is dirty and does not flush the change to the database. This does not happen in Hibernate 3.1.1 After tracing through Hibernate I identified the bug. This is due to a change in the 3.2 branch in EntityUpdateAction http://fisheye.jboss.org/browse/~br=tag%3Av321/Hibernate/tags/v321/Hibern... The deepCopy is done only when hasUpdateGeneratedProperties() is true, which I is not for our User object. So the set is not deepCopy and the lastUpdated array got a reference to the the same set as the user object. Any modification is so done in the lastUpdated and the User entity, making the object non dirty. rollbacking to the 3.1.1 version of this file probably fix the issue.

[Hibernate-JIRA] Created: (HHH-2113) Incorrect join ordering with filters and JOINED inheritance

by Barney Boisvert (JIRA)

[Hibernate-JIRA] Created: (HHH-2365) Incorrect parameter order for parameters used as map-key in HQL

by Hendrik D (JIRA)

Incorrect parameter order for parameters used as map-key in HQL --------------------------------------------------------------- Key: HHH-2365 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2365 Project: Hibernate3 Type: Bug Components: query-hql Versions: 3.2.1 Reporter: Hendrik D When using parameters in HQL for the key of a domain object map in the where-clause, the query parsing mechanism results in an SQL query with the parameters used in the wrong places. Since my real domain objects require you to know too much of the application I'm writing, I'll describe the problem with a simplified setup: CLASSES: ------- class Foo { int id; int meaninglessNumber; Map<Language, Document> documents; } class Document { int id; String name; } class Language { String code; } TABLES: ------- FOO id meaninglessNumber documents_link_id DOCUMENTS_LINK documents_link_id language_code document_id name LANGUAGE language_code Now, let't try to retrieve all Foo that contain an english document with name "English", and have a meaninglessNumber of '5'. This is the HQL I produce: from Foo as foo where foo.meaninglessNumber = param1 and foo.documents[:param2]=:param3 These are the parameter values: param1 = int 5 param2 = Language {code="en"} param3 = String "English" I expect an sql query like this: select * from foo foo0_ inner join documents documents1_ where foo0_.documents_link_id = documents1_.documents_link_id and documents1_.language_code = 'en' and foo0_.meaninglessNumber = 5 and documents1_.name = 'English' But instead, the real query looks like this: select * from foo foo0_ inner join documents documents1_ where foo0_.documents_link_id = documents1_.documents_link_id and documents1_.language_code = 5 and foo0_.meaninglessNumber = 'en' and documents1_.name = 'English' The subtle difference is, that the parameters param1 and param2 seem to be switched! A lot of debugging pointed out that the order of the indexes is determined based on the HQL, resulting in the following indexes: param1 -> 1 param2 -> 2 param3 -> 3 In the generated SQL, all parameters are replaced by '?', and on execution, these are replaced one by one, following the order of the parameter indexes. While creating the SQL, the map key parameter is transformed into 'documents1_.language_code = ?'. No problem here, but this condition is placed in the beginning of the where clause, before the use of parameter param1. The indexes of the parameters should become: param2 -> 1 param1 -> 2 param3 -> 3 But this is never done! I see 3 possible ways to fix this: - Recalculate the indexes of the parameters when the sql is generated - Generate the sql in the right position, so the order of the parameters stays the same - Use named parameters in the sql and only replace them with '?' right before creating the PreparedStatement. This seems to me the most reliable way, but I guess I'm missing the point of calculating the parameter indexes and replacing them with '?' immediately...

[Hibernate-JIRA] Created: (HHH-2018) Cannot map views in postgres unless hbm2ddl.auto is unset

by Dave E Martin (JIRA)

Cannot map views in postgres unless hbm2ddl.auto is unset --------------------------------------------------------- Key: HHH-2018 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2018 Project: Hibernate3 Type: Bug Versions: 3.2.0.cr2 Environment: hibernate 3.2cr2 annotations 3.2cr1 postgresql 8.1 with postgresql-8.1-404.jdbc3.jar This is also a problem in hibernate 3.1 Reporter: Dave E Martin Attempting to map a view with hibernate results in: Exception in thread "main" org.hibernate.HibernateException: Missing table: monthly_block_totals_utc Even though this exists (as a view) in the database. making sure hbm2ddl.auto is not set allows the application to work, but at the expense of being unable to update or validate the schema (or allow the end user to control whether the schema should be updated or not). Furthermore, there doesn't appear to be a 'none' or any documented way to set .auto to something which would be the equivalent of it not being set. (or to clear it out of the properties, and setting it to null doesn't work either). This appears to be related to HHH-1329 and HHH-1473. Stepping into the process reveals that postgres apparently reports views as views and not tables, causing them to be overlooked by Hibernate when its validating. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
