DATETIME column incorrectly validates against DATE column --------------------------------------------------------- Key: HHH-5219 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5219 Project: Hibernate Core Issue Type: Bug Affects Versions: 3.5.1 Reporter: Ian Haken Attachments: validation-fix.patch org.hibernate.mapping.Table.validateColumns incorrectly validates if the expected SqlType is DATETIME and the actual SqlType is DATE. This can be reproduced as follows: Create a MySQL table with DATE type for column foo. Create an Entity with java.util.Date member foo, annotated with @Temporal(TemporalType.TIMESTAMP). Initiate a Hibernate session with hibernate.hbm2ddl.auto=validate. An exception should be thrown and is not. Looking at the code in src/main/java/org/hibernate/mapping/Table.java, it is clear why this would occur; the check is: col.getSqlType( dialect, mapping ).toLowerCase().startsWith( columnInfo.getTypeName().toLowerCase() ) I'm not sure if there was a particular reason for using startsWith rather than equals, but I've changed startsWith to equals in the suggested patch (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
