Xmlreader and Xmlwriter in Silverlight

Question

Dear All,
 
I want to create silverlight application.the application should test whether the xml file exists or not,if not exists it should create xml file programmatically and write user entered elements from textbox to the xml file and read from xml file.

Thanks in advance.

Answer 1

select empid,

(select min(attandancedate) from tbl_test where empid=a1.empid and (cast(attandancedate as time) between '08:00:00' and '09:59:59')) as intime,

(select max(attandancedate) from tbl_test where empid=a1.empid and (cast(attandancedate as time) >= '17:00:00')) as outtime

from tbl_test a1 group by a1.empid

 

 

But This Query Gives Null For Emp1 As Outtime Because He Does Not Punched After 5 PM

 

For Ideal Case We Can Remove Time from second query because we can get last punch of any employee using max, that can be use as outtime

 

Please Tell If This Is Usefull. 

 

 

 

Answer 2

select empid, min(attendencedate) as inTime, max(attendencedate) as outTime

from temp

group by empid;
