Get Dynamic Clock In or clock time in SQL

-

 Now, I am going to generate dynamic time like real punch time for Clock In or Clock Out. When we implement punch time functionality.


Create a View for Get Random value in SQL. Because SQL not allow RAND() function in user define function. So I am creating a view for this

CREATE VIEW vw_getRANDValue
AS
SELECT RAND() AS Value

Create a user define function to get real punch time. I am passing date of punch and time range in time format.

GO
CREATE FUNCTION [dbo].[FnGetPunchTime]
(@WorkingDate DATETIME,@timeRangeBegin time,@timeRangeEnd time)
RETURNS DATETIME
AS
BEGIN
    DECLARE @Result AS DATETIME;   
DECLARE @RandomTime  DATEtime, @TimeSpanInMSec int = datediff(MILLISECOND,@timeRangeBegin, @timeRangeEnd)
SELECT @RandomTime=DATEADD(MILLISECOND,(SELECT Value FROM vw_getRANDValue) *  @TimeSpanInMSec,@timeRangeBegin)
SELECT @Result=CONVERT(DATETIME, CONVERT(varchar, @WorkingDate, 23)   + ' ' + CONVERT(varchar, @RandomTime, 114))
    RETURN (@Result);
END


I am putting some data and get result using below script

DECLARE @TimeRangeBegin time = '7:45', @TimeRangeEnd time = '09:15',@WorkingDate date='2019-10-11';
select [dbo].[FnGetPunchTime](@WorkingDate,@TimeRangeBegin,@TimeRangeEnd) as PunchTime from (values(1),(2),(3),(4),(5),(6),(7)) Y(A)

Out put

ADO.NET entity is an ORM (object relational mapping) which creates a higher abstract object model over ADO.NET components. So rather than getting into dataset, datatables, command, and connection objects as shown in the below code, you work on higher level domain objects like customers, suppliers, etc. DataTable table = adoDs.Tables[ 0 ]; for ( int j = 0 ; j < table.Rows.Count; j++) { DataRow row = table.Rows[j]; // Get the values of the fields string CustomerName = ( string )row[ " Customername" ]; string CustomerCode = ( string )row[ " CustomerCode" ]; }   Benefits of using EF The main and the only benefit of EF is it auto-generates code for the Model (middle layer), Data Access Layer, and mapping code, thus reducing a lot of development time. The importance of EDMX file in Entity Framework    EDMX (Entity Data Model XML) is an XML file which contains all the mapping details of how your objects map ...

TRIGGER in sql server

 Trigger is a special kind of stored procedure that automatically executes when an event occurs in the database server. DML triggers execute when a user tries to modify data through a data manipulation language (DML) event. DML events are INSERT, UPDATE, or DELETE statements on a table or view. These triggers fire when any valid event is fired, regardless of whether or not any table rows are affected. For more information Types of DML Triggers AFTER trigger     AFTER triggers are executed after the action of the INSERT, UPDATE, MERGE, or DELETE statement is performed. AFTER triggers are never executed if a constraint violation occurs INSTEAD OF trigger     INSTEAD OF triggers override the standard actions of the triggering statement. Therefore, they can be used to perform error or value checking on one or more columns and the perform additional actions before insert, updating or deleting the row or rows. For example, when the value being updated in ...
