How to decompress internal tables?

  • Hi All,

    I use tfs, and there was necessity to downgrade tfs' sql server Enterprise edition to standard edition.

    Before to downgrade, i should decompress compressed tables. When i run the query below.

    select so.name

    from sys.partitions sp

    inner join sys.objects so on (so.object_id=sp.object_id)

    where sp.data_compression!=0

    I see there is a few internal tables with "ifts_comp_fragment_" prefix. When i execute:

    [i]ALTER Table "sys"."ifts_comp_fragment_217767833_2681" REBUILD with(DATA_COMPRESSION=NONE)

    [/i]

    I am getting the error below:

    Cannot find the object "sys.ifts_comp_fragment_217767833_2681" because it does not exist or you do not have permissions.

    How do i achive this?

    Recreate the FTS catalog. Script it out before the downgrade
