Hibernate propagates null by using a positional parameter, even if the application uses a named parameter. If there are other named parameters, then the stored procedure will fail with:
{{ Caused by: java.sql.SQLException: operation The number of parameter names does not allowed: Ordinal binding and Named binding cannot be combined! match the number of registered praremeters }}
If the application sets the null using a named parameter, then Hibernate should bind the null as a named parameter. |
