  • HI,

    Is it possible to use aggregate function with (case,when,END) condition use in pivot?

    like this (PIVOT (count(Shift_Description) FOR Detail_Date IN (‘ + @cols + ‘)) AS Pvt’)

    Below example :-

    SELECT
    DISTINCT Detail_Date INTO #Dates
    FROM
    Detail
    — WHERE Detail_Date between @StartDate AND @EndDate
    ORDER BY Detail_Date

    DECLARE @cols NVARCHAR(4000)
    SELECT @cols = COALESCE(@cols + ‘,[‘ + CONVERT(varchar, Detail_Date, 106)
    + ‘]’,'[‘ + CONVERT(varchar, Detail_Date, 106) + ‘]’)
    FROM #Dates
    ORDER BY Detail_Date

    DECLARE @qry NVARCHAR(4000)
    SET @qry =
    ‘SELECT Fname AS F,’ + @cols + ‘ FROM
    (SELECT Fname, Detail_Date,Shift_Description
    FROM Detail)p
    PIVOT (count(Shift_Description) FOR Detail_Date IN (‘ + @cols + ‘)) AS Pvt’
    print +@qry
    EXEC(@qry)

    f possible, can you please suggestion how to use it?

  • write an SQL query that returns the sum of the numbers in column v.

    For example, given:

    v

    2
    10
    20
    10
    your query should return 42.
    Code please

  • How can I get size of a column in a table ? I mean if I want to know, size of some particular column is there any command like sp_spaceused ? I believe sp_Spaceused give size of only table and not particular Column.

  • SELECT * FROM TB_NAME
    ORDER BY COLUMN NAME
    OFFSET 4 ROWS FETCH NEXT 3 ROWS ONLY
