I am trying to indent a scroll-thru menu which has been made into a tree using the
following database query:
select dept_id, LPAD(' ',2*(Level-1))||dept_name dept_name
from depts
start with dept_id = 1
connect by dept_parent = PRIOR dept_id;
My problem is that the query uses spaces to indent the list, and spaces seem to be
automatically removed from the beginnings of items in scroll-thru menus. To remedy
this, I have decided to replace the spaces with underscores. This is where I become
confused.
s/ /_/g replaces even spaces between words in the list;
s/^(_*) /_/g would require multiple iterations to catch all the spaces...
Is there a simple way to replace one thing with another in the amount in which the
first thing appeared? Ex.: 2 spaces becomes 2 underscores, 4 becomes 4, etc. Thank
you for any help.
