Version: 0.1.0
[SQL]irisowner@/usr/irissys/:USER>

Soporta stdin, así que se pueden canalizar algunos ficheros SQL con un grupo de consultas SQL y comandos irissqcli. Por ejemplo, este comando producirá 3 ficheros en diferentes formatos (de entre más de 20 formatos disponibles).

$ cat <<EOF | irissqlcli iris://_SYSTEM:SYS@localhost:1972/USER

.mode csv;
tee -o test.csv;
select top 10 TABLE_SCHEMA,TABLE_NAME 
from information_schema.tables 
order by TABLE_SCHEMA,TABLE_NAME;
notee;

.mode latex;
tee -o test.tex;
select top 10 TABLE_SCHEMA,TABLE_NAME 
from information_schema.tables 
order by TABLE_SCHEMA,TABLE_NAME;
notee;

.mode html;
tee -o test.html;
select top 10 TABLE_SCHEMA,TABLE_NAME 
from information_schema.tables 
order by TABLE_SCHEMA,TABLE_NAME;
notee;

EOF
