The common basic usage is fairly simple to translate: * MySQL ([docs](https://dev.mysql.com/doc/refman/8.0/en/aggregate-functions.html#function_group-concat)): `GROUP_CONCAT( field_name SEPARATOR 'some_separator' )` * SQLite ([docs](https://www.sqlite.org/lang_aggfunc.html#group_concat)): `GROUP_CONCAT( field_name, 'some_separator' )` Technically the MySQL implementation is has more options, but I suspect the above covers the majority of uses.
