## AQL - MovieDB Usage

#### With taql :

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 MovieDB

Then 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.

#### With tace :

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 MovieDB

Any 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.
