Dbschema outputs -284 error in SE 7.24FC6 on Alpha 4.0d

Hi All, Running dbschema -t <table> -d <database> -ss encounters the -284 error: A subquery has returned not exactly one row Can some explain a bit what dbschema is trying to do here ... We also get the -100 Error: which is ISAM error: duplicate value for a record with unique key We are encountering this all over the place for our client mostly running on the Alpha servers. Most likely they are running version 4 and up. This problem has been documented with Informix as a bug I believe. Not sure ... in any case ... does anyone have a resolve to this issue. It is quite cumbersome for these errors to occur on more than 100 tables in our database which contains over 300 tables. I am running out of time ... and dropping and recreating tables and indexes seems to resolve the duplicate error problem but does not always solve the issue with the subquery problem. If you can ... it would be helpful to know a bit more about what dbschema is trying to do ... the tables it pulls from and such ... because I am at a lost to a resolve other than what I mentioned.
