Thanks @formerstaff & @jeffreystables for pointing me in the right direction. I was able to make getTables method work in live api (but it took me a while to find where the db call is being made in df-sqldb-core). Other API methods are still not working which means I need to edit their queries as well. This doesn’t seem good to me editing the underlying system directly as I couldn’t figure out a way to make changes which will allow DF to work with sybase and sql server both. My current job role doesn’t doesn’t allow me to explore this further. Sybase is not popular DB but its still used in enterprise legacy systems. So hoping somebody would add this integration or better DFv2.0 comes with ODBC support but its still a long wait for production env.
