    Unanswered: update statistics INFORMIX

    Hi all,

    Do I have to run Update Statistics on a TABLE where I just added a field?

    Cheers,

    my update Statistics script:

    update statistics medium for table "TABLE" distributions only;
    update statistics high for table "TABEL" ("INDEX FIELD");
    update statistics high for table "TABEL" ("INDEX FIELD");
    update statistics high for table "TABEL" ("INDEX FIELD");
    update statistics high for table "TABEL" ("INDEX FIELD");

    Hi,

    IBM-INFORMIX, suggest execute update statistics high for first columns of index, update statistics medium for reminder of colums in index and update statistics low for table all.
    Later update statistics for procedures.

    Gustavo.
