[Hibernate-JIRA] Created: (HBX-902) Support naming / renaming HQL editor tabs

by Joseph Marques (JIRA)

Support naming / renaming HQL editor tabs ----------------------------------------- Key: HBX-902 URL: http://opensource.atlassian.com/projects/hibernate/browse/HBX-902 Project: Hibernate Tools Type: New Feature Versions: 3.2beta8 Reporter: Joseph Marques Right now, if I open multiple HQL editors under the same configuration they are ALL named "HQL: <configuration>" When I have 3 or 4 of them open, I sometimes forget which query is in which, so I waste time poking around to find the right one. If they could be suffixed with the unique user-chosen token, then they would be much easier to work with. So something like: "HQL: <configuration>: <name>" Or, even better, since HQL isn't really needed (because the HQL editor has a distinct editor icon), it could be removed entirely, leaving us with: "<configuration>: <name>" Thoughts? -- 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-2399) FlushMode.AUTO practically unusable - should not flush before EVERY query

by Piotr Kołaczkowski (JIRA)

FlushMode.AUTO practically unusable - should not flush before EVERY query ------------------------------------------------------------------------- Key: HHH-2399 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2399 Project: Hibernate3 Type: Improvement Versions: 3.1.3, 3.2.1, 3.2.2, 3.2.0.ga Environment: PostgreSQL 8.1.5, JDBC 2 and 3, Linux kernel 2.4.x, 2.6.x, Java 1.5.0_09 Reporter: Piotr Kołaczkowski Attachments: hbtest.zip The method flushIfRequired seems to flush before every query execution, even though there wasn't anything changed to the objects in the session, and the objects in the session are of different class than the object(s) queried. When having more than a few such objects in a session, it may lead to large, unneeded overheads (I noticed 10-200 times slowdown on simple queries). Our system uses many fast queries, that uasually return only one result or few results. The average query durations on different levels, measured by System.nanoTime() (see the attachment): - database level: 0.05 ms - pure JDBC code, prepared statements: 0.2 ms - pure JDBC code, no prepared statements: 0.7 ms - not cached hibernate query, no other objects associated with the session: 1.3 ms - cached hibernate query, object in the session cache, no other objects associated with the session: 1.1 ms - cached hibernate query, 10000 very simple objects of some other class in the session: >50 ms 10000 may seem large, but note these were very simple objects, having only 2 properties. On our production system we have classes with many properties, and even 20 objects in a session can cause a sub-millisecond query to run longer than 5 ms. We switched to FlushMode.COMMIT, and now the performance is much better. Can you do something about this? As far as I've read in JIRA, a similar issue exists in Hibernate 2.x, and is still OPEN / UNRESOLVED. BTW. Why is the 1st level cache so slow in my tests? Why reading just a 2 field object from the database cause so much overhead over pure JDBC? What am I doing wrong? There is so much marketing about using cglib reflection optimizer in the performance FAQ but even if I retrieved these objects using JDBC and reflection, I would achieve much better performance. After all 1 ms is very much time, if getting results from DB and sending them to JVM lasts 0.2 ms. -- 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-2347) Improvement to DerbyDialect default identy generation mode

by Fabrizio Giustina (JIRA)

Improvement to DerbyDialect default identy generation mode ---------------------------------------------------------- Key: HHH-2347 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2347 Project: Hibernate3 Type: Patch Versions: 3.2.1 Reporter: Fabrizio Giustina Attachments: DerbyDialect-identity.diff although derby supports identities org.hibernate.dialect.DerbyDialect strangely uses an HiLo generation strategy for ids (for any other dialects that support identities IdentityGenerator is the default). Even more curiously, DerbyDialect overrides getIdentityColumnString() from the Db2 dialect by using "generated ALWAYS as identity" instead of "generated BY DEFAULT as identity". Derby however fully supports "by default" in identities as clarified in http://db.apache.org/derby/docs/10.1/ref/rrefsqlj37836.html . "by default" should be preferred since it allows a direct insertion when needed (and I can't see no reason why enabling it for db2 and not for derby). The patch attached simply deletes two methods, so that the default implementation from Db2Dialect is used: - removing getIdentityColumnString() make derby use "by default" identities like db2 already does - removing getNativeIdentifierGeneratorClass() make it choose IdentityGenerator.class (it falls back to the default strategy used in org.hibernate.dialect.Dialect) note that part of this issue has already been reported in HHH-1918 (not addressing the identity generation string) -- 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-2413) Offer a way to log bound jdbc parameters in a uniform way for UserType implementors

by Baptiste MATHUS (JIRA)

Offer a way to log bound jdbc parameters in a uniform way for UserType implementors ----------------------------------------------------------------------------------- Key: HHH-2413 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2413 Project: Hibernate3 Type: Improvement Versions: 3.2.2 Reporter: Baptiste MATHUS Priority: Minor At the moment, when someone implements a UserType, the bound parameters won't be displayed in not explicitly displayed via loggers. For example, here is what the code of NullableType.nullSafeGet() is : public final void nullSafeSet(PreparedStatement st, Object value, int index) throws HibernateException, SQLException { try { if ( value == null ) { if ( IS_TRACE_ENABLED ) { log().trace( "binding null to parameter: " + index ); } st.setNull( index, sqlType() ); } else { if ( IS_TRACE_ENABLED ) { log().trace( "binding '" + toString( value ) + "' to parameter: " + index ); } set( st, value, index ); } } catch ( RuntimeException re ) { log().info( "could not bind value '" + toString( value ) + "' to parameter: " + index + "; " + re.getMessage() ); throw re; } catch ( SQLException se ) { log().info( "could not bind value '" + toString( value ) + "' to parameter: " + index + "; " + se.getMessage() ); throw se; } } IMO, it would be quite a good thing to provide some method in Hibernate, something like logBoundParameter() that would do the log like above : > log().trace( "binding '" + toString( value ) + "' to parameter: " + index ); This method could then be just called by implementors so as to guaranty the display is always the same about bound parameters. Even more, I think it should use a special logger, just like the org.hibernate.SQL one to display this parameters. In fact, at the moment, I feel the reference documentation is not very clear about this : see http://www.hibernate.org/hib_docs/v3/reference/en/html/session-configurat.... It says : > org.hibernate.type Log all JDBC parameters But that's not completely true: it will only log bound parameters that are parameters typed with standard types coming from the org.hibernate.type package. Any custom UserType won't display anything until you: 1) put the right log4j line for the package where your userType is located ; 2) think about explicitly logging those parameter values in your custom UserType (cf. my first point). I'm not sure I made myself totally clear,. If so, please let me know. If you think that would be worth an improvement, I'll give a look to provide a patch for this. Thanks a lot. -- 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-2845) "Another ORA-00907: missing right parenthesis" bug with Oracle

by Dean Pullen (JIRA)

"Another ORA-00907: missing right parenthesis" bug with Oracle -------------------------------------------------------------- Key: HHH-2845 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2845 Project: Hibernate3 Issue Type: Bug Affects Versions: 3.2.5 Environment: hibernate-entitymanager.jar (3.3.1ga) hibernate-annotations.jar (v 3.3.0ga) hibernate-commons-annotations.jar (within Hibernate Annotations.rar\lib) ejb3-persistence.jar (within Hibernate Annotations.rar\lib) hibernate3.jar (v 3.2.5.ga) Oracle 10g Reporter: Dean Pullen I'm using JBoss 4.2.1GA, with the Hibernate environment described above, using Oracle 10g, and attempting to perform a query. I've been receiving a "ORA-00907: missing right parenthesis" error when attempting to perform the query. Now a similar bug had this down to Hibernate using the 'as' keyword in the query, aliasing the table name - something that has been fixed in Hibernate 3.3.0ga. (Aliasing a table in the SQL spec is optional, Oracle doesn't support it) But I still get the same error. The query still contains the 'as' keyword (but not aliasing a table) Here is an example: I have two tables. CSIUsers and CSIUserSurveys. There is a one-to-many mapping between CSIUsers to CSIUserSurveys. Query query = entityManager.createQuery("FROM " + CSIUser.class.getSimpleName() + " cu LEFT JOIN cu.csiUserSurveys us" + " WHERE NOT EXISTS (SELECT us FROM cu.csiUserSurveys us WHERE us.csiUserId = cu.csiUserId)"); Result: [[14 Sep 2007 15:43:52] DEBUG org.hibernate.util.JDBCExceptionReporter - could n ot execute query [select csiuser0_.CSI_USER_ID as CSI1_15_0_, csiusersur1_.CSI_U SER_ID as CSI1_16_1_, csiusersur1_.SURVEY_TYPE_CODE as SURVEY2_16_1_, csiuser0_.
