[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-5325) Minor issues in test suite and suggestions for improvements

Minor issues in test suite and suggestions for improvements ----------------------------------------------------------- Key: HHH-5325 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5325 Project: Hibernate Core Issue Type: Improvement Components: testsuite Affects Versions: 3.5.3 Environment: tested with HSQLDB 2.0 Reporter: Fred Toussi Priority: Minor hql:ASTParserLoadingTest : testComponentNullnessChecks() String query = getDialect() instanceof DB2Dialect ? "from Human where cast(? as string) is null" : "from Human where ? is null" The cast should be made by default. DB2 is highly SQL Standard conformant and displays the correct behaviour. (SQL Standard Part 3: Call-Level Interface (SQL/CLI)) Others may "invent" a character type for the dynamic param. ----------------------- legacy:FooBarTest : testFindByCriteria() if(!(getDialect() instanceof TimesTenDialect)) { list = s.createCriteria(Foo.class).setMaxResults(0).list(); assertTrue( list.size()==0 ); } The test produces the equivalent to SQL statements with "FETCH 0 ROWS ONLY" or "LIMIT 0" etc. This is explicitly stated to cause a data exception according to SQL:2008. The row count must be at least 1. ----------------------- org.hibernate.test.hql : Animal.hbm.xml This snippet is used in several tests. Search for "centimeters". <property name="heightInches"> <column name="height_centimeters" not-null="true" read="height_centimeters / 2.54" write="? * 2.54"/> </property> The target SQL column type is created as DOUBLE in most dialects. The dynamic variable in "? * 2.54" first resolves to DECIMAL because the "declared type" of the numeric literal is DECIMAL. It would be better to use "? * 2.54E0" as a hint to use DOUBLE.
