The taql program is a simple command shell that will only parse aql queries. None of the other acedb text-commands will work. it's advantage over tace for pure AQL use is that you can enter multiline queries. :
% taql MovieDBThen enter your queries after the acedb-aql> prompt. A blank line (hit RETURN twice) submit the query. The results are returned in plain text format.
Type taql -h for more options.
Tace is a more comprehensive acedb command-shell. The AQL facilities
are just part of the overall functionality. All AQL queries have to be
preceeded by the keyword "aql". This keyword allows
the setting of various output options etc.
% tace MovieDBAny tace-command that starts with
select is automatically
recognised as an AQL query and the aql-keyword can be omitted.
Type ? at the acedb> prompt for a complete listing of
possible commands.
