    Do you want the max id to be retrieved?
    The sql query is as follows.

    Select max(compid)
    from company
    group by compid

    This will get you the highest compid in your table.

    Following is your required query

    Select max(Compid) from company1

    you can also use the group functions

    AVG ( [ DISTINCT | ALL ] col ) col = column name The average value of that column
    COUNT ( * ) none Number of rows returned including duplicates and NULLs
    COUNT ( [ DISTINCT | ALL ] col ) col = column name Number of rows where the value of the column is not NULL
    MAX ( [ DISTINCT | ALL ] col ) col = column name Maximum value in the column
    MIN ( [ DISTINCT | ALL ] col ) col = column name Minimum value in the column
    SUM ( [ DISTINCT | ALL ] col ) col = column name Sum of the values in the column
    CORR ( e1, e2 ) e1 and e2 are column names Correlation coefficient between the two columns after eliminating nulls
    MEDIAN ( col ) col = column name Middle value in the sorted column, interpolating if necessary
    STDDEV ( [ DISTINCT | ALL ] col ) col = column name Standard deviation of the column ignoring NULL values
    VARIANCE ( [ DISTINCT | ALL ] col )

    Where Cmp.Rnk=1

    3) Select * from
    (Select Rank() Over (order by CompanyID ASC) as Rnk from Company) AS Cmp
