[Hibernate-JIRA] Created: (HHH-2448) Generate identical column aliases among cluster

by Loïc LEFEVRE (JIRA)

Generate identical column aliases among cluster ----------------------------------------------- Key: HHH-2448 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2448 Project: Hibernate3 Type: Improvement Components: query-sql Versions: 3.2.2 Environment: Hibernate version: 3.2.2, 2.1.8 Database: Oracle 9.2.0.8 Reporter: Loïc LEFEVRE Attachments: report_1.txt, report_2.txt Among our weblogic cluster (12 instances), we can see that a query can have different column aliases. Although all seems correct, when regarding database reports like StatsPack or Spotlight we can see that because of these different aliases, the reports are wrong. Indeed, a resource consuming query can see its associated report properties (cpu usage, buffer gets, number of executions...) divided by the number of weblogic instances of our cluster (i.e. divided by 12) thus preventing us to pinpoint the queries to look at. On a 3 instances cluster, we can see this report: REPORT#1: one statement with a poor number of buffer gets/execution is reported splitted in 3, see the alias generated for column DTO.CREATION_DATE for example On a 4 instances cluster, we can see this report: REPORT#2: one statement responsible of the latch free/cache buffers chains wait events splitted in 4, note the column alias generated fordeffcashcy0_.BEST_EXPECTED_CY More than confusing the DBAs about the same query with n different "faces", our reports don't show us all the queries to look at: indeed, in our "Top 50 queries", a lot of them are duplicates! Also the memory required in the SGA to store the queries, the execution plan and so on is increased... Finally, although the column aliases can have up to 30 characters under Oracle, the limit is set to 10, why? -- 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

by Avinash THM (JIRA)

@UniqueConstraint annotation not creating unique indexes -------------------------------------------------------- Key: ANN-787 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-787 Project: Hibernate Annotations Issue Type: Bug Affects Versions: 3.3.1.GA Environment: hibernate-core 3.3.1GA, hibernate-annotations 3.4.0GA, DB2 version 9.1 Reporter: Avinash THM Priority: Minor Unique indexes are not being created when using @UniqueConstraint annotation. The tables are created properly with primary keys and foreign keys, but the unique indexes are not created. I have posted the issue in hibernate forum (http://forum.hibernate.org/viewtopic.php?t=991505&highlight=) but didnt get any reply. I have also seen a couple of posts for the same problem. can anybody help me out with this issue? -- 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-3465) HiRDB Support

by Tomoto Shimizu Washio (JIRA)

HiRDB Support ------------- Key: HHH-3465 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3465 Project: Hibernate3 Issue Type: New Feature Components: core Affects Versions: 3.2.5 Environment: 3.2.5 + HiRDB V8 + Type4 JDBC Driver Reporter: Tomoto Shimizu Washio Attachments: hirdbdialect.patch I would like to contribute with a dialect for HiRDB, Hitachi's RDBMS. (For more information, please see http://www.hitachi.co.jp/Prod/comp/soft1/global/prod/hirdb/) I added 4 classes and slightly modified 2 existing classes as shown below. Please look at the documentation at the top of the patch for explanations. org.hibernate.dialect.HiRDBDialect (added) org.hibernate.dialect.UserFuncDeclParser (added) org.hibernate.dialect.DialectFactory (modified) org.hibernate.dialect.function.AnsiTrimEmulationFunction (modified) org.hibernate.dialect.function.AnsiTrimEmulationFunctionWithTrimstrs (added) org.hibernate.dialect.function.TypeQualifiedSQLFunction (added) You may think this code is relatively large as a dialect. It is because I also implemented user-defined function support. As HiRDB requires '?' parameters to be qualified by 'as <type>' in user-defined function invocations, I made a parser for the type declarations that the user specified in the properties file, and a renderer for the type qualifier. See javadoc comments of HiRDBDialect and UserFuncDeclParser for more details. This patch is created on Hibernate 3.2.5.ga and tested on HiRDB V8 with Type4 JDBC Driver. The example configuration for HiRDB is shown below: hibernate.dialect org.hibernate.dialect.HiRDBDialect hibernate.connection.driver_class JP.co.Hitachi.soft.HiRDB.JDBC.HiRDBDriver hibernate.connection.url jdbc:hitachi:hirdb://DBID=@HIRDBENVGRP=C:/hirdb.ini hibernate.connection.username hitachi hibernate.connection.password hitachi -- 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-2844) Limit and 'For Update' do not work on Oracle

by Michael Kopp (JIRA)

Limit and 'For Update' do not work on Oracle -------------------------------------------- Key: HHH-2844 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2844 Project: Hibernate3 Issue Type: Bug Components: query-sql Affects Versions: 3.2.2 Reporter: Michael Kopp Limits on oracle lead too: select * from (select x.y as xy_1 from table x) where rownum <= 5 when doing a for update that leads too select * from (select x.y as xy_1 from table x) where rownum <= 5 for update of x.y The problem is that the x.y is invalid and not found within the temporary view and leads to an oracle error. what would be valid is the name of the view column xy_1, meaning select * from (select x.y as xy_1 from table x) where rownum <= 5 for update of xy_1 Actually this should be valid in all cases when doing a alias for update lock. My Solution thus was to override the following in my own Oracle Dialect public String applyLocksToSql(final String sql, final Map aliasedLockModes, final Map keyColumnNames) { final String s = new ForUpdateFragment(this, aliasedLockModes, keyColumnNames) { @Override public ForUpdateFragment addTableAlias(final String alias) { // search for alias in sql final int i = sql.indexOf(alias); // check if the found string is followed by an ' as ' and thus has a column alias if (i != -1 && sql.length() > (i + alias.length() + 4) && sql.substring(i + alias.length(), i + alias.length() + 4).equals( " as ")) { // use the column alias return super.addTableAlias(sql.substring(i + alias.length() + 4, sql.indexOf(',',i + alias.length() + 4))); } return super.addTableAlias(alias); } }.toFragmentString(); return sql + s; -- 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-939) Composite IDs and many-to-many relationships

by Markus Kramer (JIRA)

Composite IDs and many-to-many relationships -------------------------------------------- Key: HBX-939 URL: http://opensource.atlassian.com/projects/hibernate/browse/HBX-939 Project: Hibernate Tools Issue Type: Bug Affects Versions: 3.2beta9 Environment: Hibrnate 3.2.1, Postgresql 8.1.8 Reporter: Markus Kramer Attachments: B.hbm.xml, testdb.sql The detection of many-to-many relationships doesn't work correctly if the primary key of one of the involved tables consists of more than one field. An example: One of two tables (table 'A') of a many-to-many relationship has a primary key consisting of two attributes (id1 and id2). The generated B.hbm.xml for the table 'B' contains this: <set name="as" inverse="true" table="a_b"> <key> <column name="b_id" not-null="true" /> </key> <many-to-many entity-name="test.A"> <column name="a_id1" not-null="true" /> </many-to-many> </set> But there should be another entry for the referenced primary key: <column name="a_id2" not-null="true" /> The SQL code for the used tables and the complete B.hbm.xml are attached. -- 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-3129) Null Role in PersitentCollection during a onCollectionRecreate() in an Interceptor

by Jose CHILLAN (JIRA)

Null Role in PersitentCollection during a onCollectionRecreate() in an Interceptor ---------------------------------------------------------------------------------- Key: HHH-3129 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3129 Project: Hibernate3 Issue Type: Bug Components: core Affects Versions: 3.2.6 Environment: Any Reporter: Jose CHILLAN When the "onCollectionRecreate" is invoked on an Interceptor, the getRole() method returns null. After investigation, the problem is located in the class CollectionEntry in one of its constructors and is easily solved using the patch : public CollectionEntry(CollectionPersister persister, PersistentCollection collection) { // new collections that get found + wrapped // during flush shouldn't be ignored ignore = false; collection.clearDirty(); //a newly wrapped collection is NOT dirty (or we get unnecessary version updates) snapshot = persister.isMutable() ? collection.getSnapshot(persister) : null; // -- ADDED LINE HERE -- role = persister.getRole(); collection.setSnapshot(loadedKey, role, snapshot); } Thanks -- 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
