I'd like to have tables from a mysql table as dataframes in nushell, but currently nushell only accepts sqlite. Is there a workaround for this?
You could use third-party tools to bridge the gap between the terminal and a MySQL Database server. mycli would be one of them, which can export into formats understood by Nu. Simple example (using a public server) going over plain CSV:
mycli mysql://anonymous@ensembldb.ensembl.org/sus_scrofa_core_56_9 --csv -e '
SELECT * FROM meta LIMIT 5
' | from csv
