Convert .NET DateTime.Ticks to SQL datetime

SQL Server > Convert .NET DateTime.Ticks to SQL datetime

A single tick represents one hundred nanoseconds or one ten-millionth of a second. There are 10,000 ticks in a millisecond.

The value of this property represents the number of 100-nanosecond intervals that have elapsed since 12:00:00 midnight, January 1, 0001, which represents DateTime.MinValue. It does not include the number of ticks that are attributable to leap seconds.





C#

var t = DateTime.Now.ToUniversalTime().Ticks; // ToUniversalTime : Converts the value of the current DateTime object to Coordinated Universal Time (UTC).

SQL Server Function to convert

create function TicksToDateTime

(@Ticks bigint)
RETURNS datetime AS
BEGIN
        -- First, we will convert the ticks into a datetime value with UTC time
         DECLARE @BaseDate datetime;
         SET @BaseDate = '01/01/1900';
         DECLARE @NetFxTicksFromBaseDate bigint;
         SET @NetFxTicksFromBaseDate = @Ticks - 599266080000000000;
-- The numeric constant is the number of .Net Ticks between the System.DateTime.MinValue (01/01/0001) and the SQL Server datetime base date (01/01/1900)
         DECLARE @DaysFromBaseDate int;
         SET @DaysFromBaseDate = @NetFxTicksFromBaseDate / 864000000000; -- The numeric constant is the number of .Net Ticks in a single day.
         DECLARE @TimeOfDayInTicks bigint;
         SET @TimeOfDayInTicks = @NetFxTicksFromBaseDate - @DaysFromBaseDate * 864000000000;
        DECLARE @TimeOfDayInMilliseconds int;
        SET @TimeOfDayInMilliseconds = @TimeOfDayInTicks / 10000; -- A Tick equals to 100 nanoseconds which is 0.0001 milliseconds
        DECLARE @UtcDate datetime;
        SET @UtcDate = DATEADD(ms, @TimeOfDayInMilliseconds, DATEADD(d,@DaysFromBaseDate, @BaseDate)); -- The @UtcDate is already useful. If you need the time in UTC, just return this value.
      -- Now, some magic to get the local time
         RETURN @UtcDate + GETDATE() - GETUTCDATE();

Get Current Url ASP.NET (VB.NET)

ASP.NET > Get Current Url

The ServerVariables collection is used to retrieve the server variable values.

SERVER_NAME: Returns the server's host name, DNS alias, or IP address
SERVER_PORT: Returns the port number to which the request was sent
SCRIPT_NAME: Returns a virtual path to the script being executed

Example: Get Current Url with parameters

Public Shared Function GetCurrentUrl()
' currentUrl
 Dim currentUrl = "http://" &HttpContext.Current.Request.ServerVariables  ("SERVER_NAME").ToString()

 If HttpContext.Current.Request.ServerVariables("SERVER_PORT").ToString() <> "" Then
    currentUrl = currentUrl + ":" + HttpContext.Current.Request.ServerVariables("SERVER_PORT").ToString()
  End If
  currentUrl = currentUrl + HttpContext.Current.Request.ServerVariables ("SCRIPT_NAME").ToString()
 If HttpContext.Current.Request.QueryString.ToString() <> "" Then
   currentUrl += "?" + HttpContext.Current.Request.QueryString.ToString()
 End If
 Return currentUrl
End Function

SqlCommand CommandTimeout Property

C# > Data > SqlCommand > CommandTimeout

The time in seconds to wait (timeout) for the command to execute. The default is 30 seconds.

A value of 0 indicates no limit and will wait indefinitely until command is executed.

Example:

SqlConnection con = new SqlConnection("connString");
SqlCommand com = new SqlCommand("exec your_stored_procedure", con);
com.CommandTimeout = 60;

Convert number to datetime SQL Server

SQL Server > Built-in Functions > CAST > Numbers to Date

Sometimes we need to convert numbers (year, month, day) to date like DateSerial.

In order to be independent of the language and locale settings, you should use the ISO 8601 YYYYMMDD format - this will work on any SQL Server system with any language and regional setting in effect.

Example:

declare @year int

declare @month int
declare @day int

set @year = 2012

set @month = 9
set @day = 30

SELECT

CAST(
CAST(@year AS VARCHAR(4)) +
RIGHT('0' + CAST(@month AS VARCHAR(2)), 2) +
RIGHT('0' + CAST(@day AS VARCHAR(2)), 2)
AS DATETIME)

Result:

2012-09-30 00:00:00.000
