Hello,
the best way to join two databases for example from Oracle to MSSQL is to use ADBC. ADBC is a software package that expands the Oracle database. Once installed, you can select the MSSQL tables that should be visible in Oracle.
If you like, we can assist you installing ADBC and developing the necessary functions for MSSQL to Oracle access.
Please send me a mail to
m.peter@alligatorsql.com if you need further help in this way.
Hope that helps ?
