Tristan Lins ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *commented* on HHH-16253 ( https://hibernate.atlassian.net/browse/HHH-16253?atlOrigin=eyJpIjoiOWViZj... ) Re: [Envers] Schema Validation Failure With Audited (N)Clob Column with Hibernate 6 on H2 ( https://hibernate.atlassian.net/browse/HHH-16253?atlOrigin=eyJpIjoiOWViZj... ) I digged into the code and there is something strange. In both cases, for the Entity#conlusion and Entity_audit#conclusion no Column#setSqlTypeName ( https://github.com/hibernate/hibernate-orm/blob/6.2.6/hibernate-core/src/... ) is set (the setter is called with NULL ). When the Column#getSqlTypeName ( https://github.com/hibernate/hibernate-orm/blob/6.2.6/hibernate-core/src/... ) getter is called, the sql type is detected using the ddlTypeRegistry ( https://github.com/hibernate/hibernate-orm/blob/6.2.6/hibernate-core/src/... ). There are different results. For the Entity class: getSqlTypeCode( mapping ) = 2005 getColumnSize( dialect, mapping ) = Size(length = 255, scale = 2) ddlTypeRegistry.getTypeName( getSqlTypeCode( mapping ), getColumnSize( dialect, mapping ) ) = "oid" But for the Entity_audit class, the ddlTypeRegistry returns varchar: getSqlTypeCode( mapping ) = 12 getColumnSize( dialect, mapping ) = Size(length = 255, scale = 2) ddlTypeRegistry.getTypeName( getSqlTypeCode( mapping ), getColumnSize( dialect, mapping ) ) = "varchar(255)" But the issue is not here, the sqlTypeCode was set before. When BasicValue#resolveColumn ( https://github.com/hibernate/hibernate-orm/blob/6.2.6/hibernate-core/src/... ) is called, the resolution differs. For the Entity class, the resolution is: InferredBasicValueResolution( jdbcType = ClobTypeDescriptor(CLOB_BINDING) jdbcMapping = basicType(java.lang.String, 2005) legacyType = basicType(java.lang.String, 2005) ) And for the Entity_audit class, the resolution is: NamedBasicTypeResolution( basicType = basicType(java.lang.String, 12) ) I’m still searching why the NamedBasicTypeResolution has the wrong type.
