No but there is a way to delete them:
Code:
select "DROP INDEX "||trim(owner)||"."||trim(idxname)||";"
from sysindexes
where owner="informix";
run, copy, paste, run, be happy
Nicer version with DBAccess
Code:
select "INDEX "||trim(owner)||"."||trim(idxname)||";" DROP
from sysindexes
where owner="informix";
You can also build a stored procedure to do this.
