    Unanswered: Question SQL

    Hi colleagues,
    I have this query.
    select * from table where field = ? and field1 = ? and field2 = ?

    I need to analize this query with
    db2expln -d bbdd -g -i -z \; -f query.sql -t

    can someone tell me which values ​​replace question marks (?)

    Thank you for advanced.

    When parameter markers are used, DB2 optimizer assumes a normal distribution for that column.
