Backport the functionality to permit propagation of NULL to the database for parameters in stored procedure invocations. Setting ibernate.proc.param_null_passing="true" will globally enable passing null as the stored procedure parameter values when no value is provided.
Default will be "false".
NOTE:
HHH-9548 allows the global value to be overridden on a per parameter basis; this functionality cannot be backported to 5.0 due to SPI changes.
Note: The 5.0 documentation [section 22.7|http://docs.jboss.org/hibernate/orm/5.0/userguide/html_single/Hibernate_User_Guide.html#configurations-query] currently documents the use of {{hibernate.proc.param_null_passing}} but this property is ignored in 5.0. |
