    I am able to collect and display statistics using sp_createstats and DBCC SHOW_STATISTICS, but I need to use those values for some calculations. Is there any way by which I can query those values to extract them ? or is there any table where those values are stored ?

    explain in more detail
    you probably will have to use the options below:

    DBCC SHOW_STATISTICS ( 'table_name' | 'view_name' , target )

    basically, run each option, inserting results into a table,
    then query it
    this is not a cheap option

    Hi joechang,

    for instance i am running


    where Employee is my table name and sample_stat is my statistic name (basically the index).
    The result of this is displayed in the results window but it gets stored in form of a blob in the sysindexes table and hence i cannot query it. I was keen to know whether there is any method by which i can access the results by querying them (since i dont get anything from the blob entries)

    Visit the following link for code samples andhttp://www.microsoft.com/usa/webcasts for the webcasts. If not you can use XML to display the relevant data, as explained there is no easy way.
