           "SAMPLE"."STATUS",   
           "SAMPLE"."RECD_DATE",   
           "SAMPLE"."DATE_AUTHORISED",

           "SAMPLE"."RELEASE_DATE",

           "SAMPLE"."DATE_COMPLETED",   
  
           TRUNC((((86400 * (DATE_COMPLETED-RECD_DATE))/60)/60)/24) AS VC_Days,
  	 		TRUNC(((86400 * (DATE_COMPLETED-RECD_DATE))/60)/60) - (24 * (TRUNC((((86400 * (DATE_COMPLETED-RECD_DATE))/60)/60)/24))) AS VC_Hrs,
  	 		TRUNC((86400 * (DATE_COMPLETED-RECD_DATE))/60) - (60 * (TRUNC(((86400 * (DATE_COMPLETED-RECD_DATE))/60)/60))) AS VC_Min,

  Hi mmazeemahmad,

  It seems your oracle query only selects date ,hour, seconds between two date.

  SqlServer has function for date calculation. Below is my sample.

  getDate() gets the current date , dateadd(day,1,getDate()) gets tomorrow's date.

  datediffer(interval, date1,date2) gets the difference between date2 and date1 , interval specifies unit of the result 

  You could specify day to get the day difference , hour to get the hour difference  and so on.

   select datediff(day,getDate(),dateadd(day,1,getDate()))   
   select datediff(hour,getDate(),dateadd(day,1,getDate()))
   select datediff(minute,getDate(),dateadd(day,1,getDate()))  -- get minute difference
   select datediff(second,getDate(),dateadd(day,1,getDate()))  -- get second difference

  So you could write your query similar to the query below  in sqlserver

  SELECT "SAMPLE"."ID_NUMERIC",   
           "SAMPLE"."BATCH_NO",   
           "SAMPLE"."STATUS",   
           "SAMPLE"."RECD_DATE",   
           "SAMPLE"."DATE_AUTHORISED",   
           "SAMPLE"."TEMPLATE_ID",   
           "SAMPLE"."RELEASE_DATE",
           "SAMPLE"."LOGIN_DATE",
           "SAMPLE"."DATE_COMPLETED",   
  
          datediff(day,RECD_DATE,DATE_COMPLETED)    AS VC_Days,
  	  datediff(hour,RECD_DATE,DATE_COMPLETED) 		 AS VC_Hrs,
  	 	 datediff(minute,RECD_DATE,DATE_COMPLETED)	 AS VC_Min,
  	 	datediff(second,RECD_DATE,DATE_COMPLETED) AS VC_Sec,
           
        datediff(day,RECD_DATE,RELEASE_DATE)    AS VR_Days,
  	 datediff(hour,RECD_DATE,RELEASE_DATE) 	 AS VR_Hrs,
  	 	datediff(minute,RECD_DATE,RELEASE_DATE)  AS VR_Min,
  	 	datediff(second,RECD_DATE,RELEASE_DATE)  AS VR_Sec,
  
  	 		 datediff(day,DATE_COMPLETED,DATE_AUTHORISED) CA_Days,
  	 		 datediff(hour,DATE_COMPLETED,DATE_AUTHORISED) AS CA_Hrs,
  	 	 datediff(minute,DATE_COMPLETED,DATE_AUTHORISED) AS CA_Min,
  	 		 datediff(second,DATE_COMPLETED,DATE_AUTHORISED) AS CA_Sec,
  
  	 		datediff(day,RECD_DATE,DATE_AUTHORISED) AS VA_Days,
  	 		 datediff(hour,RECD_DATE,DATE_AUTHORISED) AS VA_Hrs,
  	 		 datediff(minute,RECD_DATE,DATE_AUTHORISED) AS VA_Min,
  	 		 datediff(second,RECD_DATE,DATE_AUTHORISED) AS VA_Sec
  
      FROM "SAMPLE"  
  

  There may be some differences from what you need in sql query, please change the query according to your requirement when you find any mismatch in my query.

  Best regards,

  Ackerly Xu
