As expected all those "hint" work in sdsql as well. What's new is there is a "set sqlformat" command so that all results come out in that format. So, all the same formats work : xml, html, delimited, insert, loader, fixed, text. Also there's a new one named ansiconsole which is described here.
Now with the new things being added it could be easy to create a "build" script of sorts. Combine this with the new ddl command into something like this
SQL>set sqlformat insert
SQL>select * from emp;
SQL>apex export 101
What you would end up with out of this is a sql script with the ddl and data for emp and the Apex App export. This script could then be checked in, given to a DBA, or even just for a nightly backup of sorts.
