Querying statistics

  • Ok, I'm not sure what I'm doing wrong here, but pretty sure my 2005 statement is fine, my 2000 is the issue. It has to be on my join ... I'm pulling back to much data ...

    I know it's gonna be glaringly obvious, but I'm not seeing it ...

    2000

    SELECT

    o.nameAS [Table Name]

    ,i.nameAS [Index Name]

    ,CASE indid

    WHEN 0 THEN 'HEAP'

    WHEN 1 THEN 'CLUSTERED'

    ELSE'NON CLUSTERED'

    ENDAS [Index Type]

    ,STATS_DATE(i.id, i.indid)AS [Last Stats Update]

    FROM sysobjects o

    INNER JOIN sysindexes i

    ON o.id = i.id

    WHERE o.type = 'U'

    AND i.indid > 0

    ORDER BY 1,2,4

    2005

    SELECT

    t.nameAS [Table Name]

    ,i.nameAS [Index Name]

    ,i.type_descAS [Index Type]

    ,STATS_DATE(i.OBJECT_ID,i.index_id) AS [Last Stats Update]

    FROM

    sys.indexes i JOIN

    sys.tables t ON t.OBJECT_ID = i.OBJECT_ID

    WHERE i.type > 0

    ORDER BY 1,2,4

  • Well, sys.indexes does not pull back all the objects that sysindexes does ... so perhaps I'm doing it wrong in 2k5.

    Any advice would be most welcome.

    Thanks

  • Hi Adam,

    In 2000, you are also seeing the Statistics of the tables as well. Atleast that is what I am seeing here. They all start with _WA. I modified your query a bit and got the right number of rows.

    SELECT

    o.nameAS [Table Name]

    ,i.nameAS [Index Name]

    ,CASE indid

    WHEN 0 THEN 'HEAP'

    WHEN 1 THEN 'CLUSTERED'

    ELSE'NON CLUSTERED'

    ENDAS [Index Type]

    ,STATS_DATE(i.id, i.indid)AS [Last Stats Update]

    FROM sysobjects o

    INNER JOIN sysindexes i

    ON o.id = i.id

    WHERE o.type = 'U'

    AND i.indid > 0

    and i.name not like '_WA%'

    ORDER BY 1,2,4

  • Yeah I saw that ... what are those _WA tables?

  • If I am not mistaken, they are the Statistics details of each Object.These are Statistics generated by the system itself.

  • Ah ok, well, thanks for the help and info!
