摘要:
A system, method, and program product are provided that identifies a remote stored procedure stored in a remote database management system, and automatically generates a local stored procedure stored in a local database management system. To automatically generate the local stored procedure, local and remote metadata are gathered corresponding, respectively, to a local database management system and a remote database management system. The remote metadata is used to create a call statement to the remote stored procedure. The created invocation method maps input values, input to the local stored procedure, to input parameters of the remote stored procedure. Results in the local stored procedure are set by mapping the data returned from the remote stored procedure to the corresponding return values (e.g., parameters and result sets) in the local stored procedure values.
