Hello enclave_Research,
Since the database access library is untrusted, it cannot be called directly from inside the enclave. Instead, you can create interface functions in your untrusted app that access the database. Then create ocall into the untrusted interface functions. The enclave indirectly accesses the database via ocalls to the interface functions in your untrusted app.

Hello encalve_Research,
This error occurs when trying to sign an enclave DLL that has been dynamically linked to a library. Enclaves can only be statically linked. Please see page 56, section Linking Enclave with Libraries, of the SGX SDK Wihdows Developer Reference, https://software.intel.com/content/www/us/en/develop/download/sgx-sdk-developer-reference-windows.html.
