Question Abdulaziz Alenazi · Dec 22, 2021 Issue with changing the ODBC driver from cache to IRIS Hi folks We are upgrading TrakCare from 2017 version to 2020, when I tried to reconnect our applications with new upgraded environment through IRIS ODBC driver instead of cahe ODBC driver I got this error: "the driver doesn't support the version of ODBC behavior that the application requested" while it is working fine with cache driver. Any help please ? #InterSystems IRIS for Health 0 1 0 477
