SELECT a.VPNID||'|'||a.PUBLICNUMBER||'|'||a.PRIVATENUMBER from virtualterminal a
UNION ALL
SELECT b.VPNID||'|'||b.PUBLICNUMBER||'|'||b.PRIVATENUMBER||'|'||b.PROFILEID from terminal b;
This is the code , but in the first statement as you can see there is no PROFILEID
column. I would like to write " null " to that column because we don't know the PROFILEID
of them. How can I write "null" to that column ?
Try this Query:
SELECT a.VPNID||'|'||a.PUBLICNUMBER||'|'||a.PRIVATENUMBER||'|'||'NULL'
from virtualterminal a
UNION ALL
SELECT b.VPNID||'|'||b.PUBLICNUMBER||'|'||b.PRIVATENUMBER||'|'||b.PROFILEID
from terminal b;
