connection - The connection on which to perform the work.

Returns:

null>.

Throws:

SQLException - Thrown during execution of the underlying JDBC interaction.

HibernateException - Generally indicates a wrapped SQLException.

executeReturningWork

public <T> T executeReturningWork(ReturningWork<T> work,

                           throws SQLException

Execute the discrete work encapsulated by a ReturningWork instance using the supplied connection, returning the result of ReturningWork.execute(java.sql.Connection)

Parameters:

work - The @link ReturningWork} instance encapsulating the discrete work

connection - The connection on which to perform the work.
