If you're writing a subroutine to fetch the indexes for a database, you need to code for this in the logic. Call PRAGMA table_info() on all the tables. Any row in any table_info resultset who's type is "integer" and who's pk value is 1 are indexed rowids and you just make a fake entry in your return array or whatever. Robert
