registerStoredProcedure: Register a SQL Stored Procedure with a Database


registerStoredProcedure: Uses the the StoredProcedure object to register the stored procedure with the specified database


  registerStoredProcedure(sqlSP, connectionString = NULL)



a valid StoredProcedure object


A character string (must be provided if the StoredProcedure object was created without a connection string)


TRUE on success, FALSE on failure
