[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-2740) SAPDBDialect generates wrong boolean expressions

SAPDBDialect generates wrong boolean expressions ------------------------------------------------ Key: HHH-2740 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2740 Project: Hibernate3 Issue Type: Bug Components: core Environment: SAP DB 7.6 Reporter: Matthias Wuttke Original Estimate: 10 minutes Remaining Estimate: 10 minutes The following code fragment works for MySQL, but does not for SAP-DB / MaxDB: bulkUpdate("UPDATE MyObject SET recent = false"); The query Hibernate generates is: update my_object set recent=0 The MaxDB error is "Constant must be compatible with column type and length". The following query works: update my_object set recent=false The same problem applies to SELECT queries generated by Hibernate for use with the SAPDB / MaxDB. The following class fixes the problem (if you set it as the dialect to use): public class ExtSAPDBDialect extends SAPDBDialect { @Override public String toBooleanValueString(boolean bool) { return Boolean.toString(bool); } } To fix the bug, I think one should change SAPDBDialect.toBooleanValueString(boolean). hbm2ddl has some more bugs when using it with MaxDB. eg. using ";" as the statement separator, choosing the wrong column type for Strings longer than 4000 chars (but these bugs are not that bad). ;-) Best regards Matthias
