> There is no registerFunction in the SAPDBDialect for the date extraction SQL functions (extract, day, hour...). Therefore, the inherited registration from Dialect are in effect. However, they all map to extract, which is no supported in SAPDB.
> The correct implementation is to register the following functions in SAPDBDialect.java:
> registerFunction( "second", new SQLFunctionTemplate(Hibernate.INTEGER, "second(?1)") );
> registerFunction( "minute", new SQLFunctionTemplate(Hibernate.INTEGER, "minute(?1)") );
> registerFunction( "hour", new SQLFunctionTemplate(Hibernate.INTEGER, "hour(?1)") );
> registerFunction( "day", new SQLFunctionTemplate(Hibernate.INTEGER, "day(?1)") );
> registerFunction( "month", new SQLFunctionTemplate(Hibernate.INTEGER, "month(?1)") );
> registerFunction( "year", new SQLFunctionTemplate(Hibernate.INTEGER, "year(?1)") );
> registerFunction( "extract", new SQLFunctionTemplate(Hibernate.INTEGER, "?1(?3)") );
