Running mysql 5.7.10, hibernate 4.3.11, JPA 2.1 on Weblogic 12.1.3

When using StoredProcedureQuery.registerStoredProcedureParameter, get the following warning in log:

Apr 12, 2016 2:43:02 PM org.hibernate.procedure.internal.ProcedureCallImpl prepareForNamedParameters
WARN: HHH000456: Named parameters are used for a callable statement, but database metadata indicates named parameters are not supported.

Named parameters must be supported because my code works with them. Is there a way to disable this warning, or is it a known issue? I did a search on this forum for HHH000456 and got nothing.

Hibernate just uses the JDBC java.sql.DatabaseMetaData#supportsNamedParameters method, which always returns false in the MySQL JDBC driver implementation.

So, even if MySQL does not support it natively, the Connector/J driver emulates it somehow, which is why named parameters just work, and they are even documented on the driver site.

As for the warning, you can just ignore it at the log4j level.

Thanks for the info!
