Index Size

Hi netter, Does anyone know exactly how to calculate the total index size of a particular table like you see when you do dbschema. According to the Informix Training 'Book', add 8 bytes to the length of each key, and then sum up all index entries, this should be the total index size. But this never work unfortunately. ex: { TABLE "dnguyen".foo_tbl row size = 34 number of columns = 8 index size = 70 } create table "dnguyen".foo_tbl ( f1 serial not null, f2 char(8) not null, f3 char(1), f4 char(6), f5 char(1), f6 char(1), f7 char(1), f8 char(12) ) create index "dnguyen".i_f1 on "dnguyen".foo_tbl (f8); create index "dnguyen".i_f23 on "dnguyen".foo_tbl (f2,f3); create index "dnguyen".i_f1 on "dnguyen".foo_tbl (f1); create index "dnguyen".i_f4 on "dnguyen".foo_tbl (f4); thanx in advance... ------------------------------------------------------------------------------ CSC - Partner Dzi Nguyen dinguyen@wam.umd.edu ------------------------------------------------------------------------------ -- **********************************************************
