Tom,
Join systables to sysindexes by tabid and join sysindexes to syscolumns by
the absolute value of the "part*" columns to syscolumns.colno. Each
contains the colno of one of the key columns in the index in order of
appearance. You need to use ABS(part...) because if the column is in the
index DESCENDING then its colno will be negated in sysindexes. This will
not work for 'special' indexes like functional indexes. There you will have
to parse the sysindices table that underlies the sysindexes VIEW (in 9.xx
and later sysindexes is not a table but a view into sysindices). You can
look at the code for my dbschema and dostats utilities to see how to do this
for functional indexes. See the files dostat.ec or myschema.d/
print_indexes.ec in my package utils2_ak which you can download from the
IIUG Software Repository. Feel free to borrow the print_indexes code for
you own applications if you are not producing a commercial product for sale
(then you'll have to negotiate a license with me - sorry).
