[Hibernate-JIRA] Created: (HHH-2031) Add functions to Dialect that can disable use of schema and catalog parts -- for HSQLDB support

by Brian Holmes (JIRA)

Add functions to Dialect that can disable use of schema and catalog parts -- for HSQLDB support ----------------------------------------------------------------------------------------------- Key: HHH-2031 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2031 Project: Hibernate3 Type: Patch Components: core Versions: 3.1.3 Environment: This patch is against r9668 of /tags/v313/Hibernate3. Reporter: Brian Holmes Attachments: hibernate3-v313-support_schema_catalog_names.patch HSQLDB does not support the use of three part names, that is Tables with schema and catalog parts. This patch adds two functions to Dialect: supportsSchemaNames() and supportsCatalogNames(). Table.getQualifiedName() checks these values to decide whether to use or ignore the schema and catalog parts. By default these are enabled in Dialect. This patch only disables their use in HSQLDialect. This change is necessary for people who normally use Schema and Catalog names for access their primary database, but also use HSQLDB for Unit Testing. Without it, HSQLDB is unusable for Unit Testing because it fails on use of any catalog or schema names. -- 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-2805) The class Order does not contain getters

by Aviad Lichtenstadt (JIRA)

The class Order does not contain getters ---------------------------------------- Key: HHH-2805 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2805 Project: Hibernate3 Issue Type: Improvement Components: query-criteria Affects Versions: 3.2.5 Reporter: Aviad Lichtenstadt Priority: Trivial Attachments: HibernateOrder.txt The class Order does not contain getters. This is way it is impossible to know if the ignoreCase field was set. This issue becomes more important using Hibernate Shards project. Using Shards the ordering is done using java and there is no way today to know is this property is set. i am applying a patch that adds this getter -- 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-2721) PostgreSQLDialect: function md5() always returns a string value

by Dirk Leser (JIRA)

PostgreSQLDialect: function md5() always returns a string value --------------------------------------------------------------- Key: HHH-2721 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2721 Project: Hibernate3 Issue Type: Bug Components: query-hql Affects Versions: 3.2.4.sp1 Reporter: Dirk Leser Priority: Minor The md5() function always returns a string type and not the type given as parameter. Therefore the line registerFunction( "md5", new StandardSQLFunction("md5") ); has to be changed to registerFunction( "md5", new StandardSQLFunction("md5", Hibernate.STRING) ); in class org.hibernate.dialect.PostgreSQLDialect -- 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-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

[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
