Question

I have a Program that will auto run each night, run a query, and email results. In my program I am calling a function as part of the query… What i’d like to is pass the date the program is run as the parameter. (@startdate and @enddate) @startdate will always be “today’s” date at 00:00:00 and enddate will always be “Todays date” at 23:59:59. So for example. If the program was run tonight, it would pass 1/31/13 as the date. Tomorrow, it would pass 2/1/13 as the date, the next date 2/2/13, etc. If I can do this at the query level that is fine as well… Below is my code:

SELECT
  SUM(QTY) AS Discounts
FROM
  dbo.fFinancialDataFull('Date Range Report', @startdate , @enddate, '1', '1', 'ALL', 'ALL', 'ALL', 'ALL', '1', '1', '1', '1', '1') AS fFinancialDataFull_1
WHERE
  (ReportCategoryID = 62)) AS unlimitedtbl

Answer 1

//These are the date variables.. if u need them seperately

Dim TodayDt As DateTime = DateTime.Today
Dim Tomorrow As DateTime = DateTime.Today.AddDays(1)
Dim TodayEnd as DateTime
TodayEnd = Tomorrow.AddSeconds(-1)

//This is the SQL Command that executes in SQL Server

  SELECT
  SUM(QTY) AS Discounts
FROM
  dbo.fFinancialDataFull('Date Range Report', startdate , enddate, '1', '1', 'ALL', 'ALL', 'ALL', 'ALL', '1', '1', '1', '1', '1') AS fFinancialDataFull_1
WHERE ReportCategoryID = 62
 AND startdate = TodayDt
 AND enddate = TodayEnd AS unlimitedtbl

//This is the function u need to write to make the same SQL run on VB

Public Function GetValueByDates() As String
    Dim TodayDt As DateTime = DateTime.Today
    Dim Tomorrow As DateTime = DateTime.Today.AddDays(1)
    Dim TodayEnd as DateTime
    TodayEnd = Tomorrow.AddSeconds(-1)
    Dim ReportCategoryID = 62

    Dim sql As String = "       SELECT
      SUM(QTY) AS Discounts
    FROM
      dbo.fFinancialDataFull('Date Range Report', startdate , enddate, '1', '1', 'ALL', 'ALL', 'ALL', 'ALL', '1', '1', '1', '1', '1') AS fFinancialDataFull_1
    WHERE ReportCategoryID = @ReportCategoryID
     AND startdate = @TodayDt
     AND enddate = @TodayEnd AS unlimitedtbl"

    Using cn As New SqlConnection("Your connection string here"), _
        cmd As New SqlCommand(sql, cn)

        cmd.Parameters.Add("@TodayDt", SqlDbTypes.DateTime).Value = TodayDt
        cmd.Parameters.Add("@TodayEnd", SqlDbTypes.DateTime).Value = TodayEnd
        cmd.Parameters.Add("@ReportCategoryID", SqlDbTypes.int).Value = ReportCategoryID 
     Return cmd.ExecuteScalar().ToString()
    End Using
End Function
