[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-5729) Only one check constraint is generated when @Min and @Max annotation is used on a single field

Only one check constraint is generated when @Min and @Max annotation is used on a single field ---------------------------------------------------------------------------------------------- Key: HHH-5729 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5729 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.6.0, 4.0.0.Alpha1 Environment: Hibernate Core 3.5.5-Final; Hibernate Annotation 3.5.5-Final; Oracle10gDialect Reporter: Jens Schauder Assignee: Hardy Ferentschik Fix For: 3.6.1, 4.0.0.Alpha1 Attachments: checkConstraintTest.zip When generating DDL create scripts fields which have a @Max and @Min annotation only get check constraints for the @Max constraint. Example entity class: {noformat} import javax.persistence.Entity; import javax.persistence.Id; import javax.validation.constraints.Max; import javax.validation.constraints.Min; @Entity public class TestClass { @Id private Long id; @Max(10) @Min(2) private Integer min2Max10; @Max(99999) @Min(0) private Integer min0max99; } {noformat} Code used for generating the DDL script: {noformat} public static void main(String[] args) { AnnotationConfiguration config = new AnnotationConfiguration() .addAnnotatedClass(TestClass.class); final String[] script = config .generateSchemaCreationScript(new Oracle10gDialect()); for (String string : script) { System.out.println(string); } } {noformat} Resulting output: {noformat} create table TestClass (id number(19,0) not null, min0max99 number(10,0) check (min0max99>=0), min2Max10 number(10,0) check (min2Max10>=2), primary key (id)) {noformat} I tried to locate the problem in the hibernate source code. It might be in the {{applyConstraints}} Method of the {{TypeSafeActivator}} class. It seems that it just *sets* constraints on a column and doesn't make an attempt to merge a min-constraint and a max-constraint into one check constraint.
