    Unanswered: Table index rolled-back automatically?

    Hello,

    I connected to a AS/400 database and used "IBM Data Studio" to create an index on a table:

    CREATE INDEX "TDSBFA"."WEPOH_IDX"
    ON "TDSBFA"."WEPOH"
    ("STBDE" ASC)

    The index was successfully created, and I could see it after refreshing the schema, but... after about an hour the index just disappeared. It seems that it was somehow rolled-back automatically.

    Sorry, I am a DB2 beginner, please advise.

    Regards,
    M.R.

    Indexes do not simply go away on their own. Someone or something dropped it.

    Thank you Andy, I found out what the problem is. The index is still there as there is a major query performance increase. However, IBM Data Studio does not show it any more. It's probably a bug in this application...
