sql - Multiple update rows with a column as parameter -


i'm trying update multiple rows in table:

    nip    |       attendancedate  |          intime       |           outtime    ----------------------------------------------------------------------------------------------     1105321|2016-08-30 00:00:00.000|1900-01-01 00:00:00.000|1900-01-01 00:00:00.000     1105321|2016-08-31 00:00:00.000|1900-01-01 00:00:00.000|1900-01-01 00:00:00.000     1105321|2016-09-01 00:00:00.000|1900-01-01 00:00:00.000|1900-01-01 00:00:00.000     1105321|2016-09-02 00:00:00.000|1900-01-01 00:00:00.000|1900-01-01 00:00:00.000

i want update intime & outtime .

i know can this

update attendance  set intime = '2016-08-30 08:00:00.000',     outtime = '2016-08-30 18:00:00.000' nip = '1105321' , attendancedate = '2016-08-30'

but query, must 1 one. so, question can update once? don't need update 1 one. possible? sorry bad english.

update:

so don't need 

update attendance  set intime = '2016-08-30 08:00:00.000',     outtime = '2016-08-30 18:00:00.000' nip = '1105321' , attendancedate = '2016-08-30'  update attendance  set intime = '2016-08-31 08:00:00.000',     outtime = '2016-08-31 18:00:00.000' nip = '1105321' , attendancedate = '2016-08-31'  update attendance  set intime = '2016-09-01 08:00:00.000',     outtime = '2016-09-01 18:00:00.000' nip = '1105321' , attendancedate = '2016-09-01'  update attendance  set intime = '2016-09-02 08:00:00.000',     outtime = '2016-09-02 18:00:00.000' nip = '1105321' , attendancedate = '2016-09-02'

assuming data type of attendancedate datettime, can use simple update statement , dateadd function:

update attendance set intime = dateadd(hour, 8, attendancedate),     outtime = dateadd(hour, 18, attendancedate) nip = '1105321'

the statement updates rows condition nip = '1105321' met (as defined where statement). if want update every row, remove where statement.

intime calculated adding 8 hours attendancedate, , outtime - adding 18 hours attendancedate.

if store date string, need casting string datetime, , cast when done, or choose use string manipulation.

c# - Check Keyboard Input Winforms -

i wondering if instead of doing this protected override void onkeydown(keyeventargs e) { if (e.keycode == keys.a) console.writeline("the key down."); } i set bool method , this: if(keydown(keys.a)) // whatever here i've been sitting here ages trying figure out how it. can't wrap head around it. in case wondering, plan call bool inside different method, check input. since want perform action after pressing key, using keydown event enough. but in cases suppose want check if specific key down in middle of process, can use getkeystate method way: [dllimport("user32.dll", charset = charset.auto, exactspelling = true)] public static extern short getkeystate(int keycode); public const int key_pressed = 0x8000; public static bool iskeydown(keys key) { return convert.toboolean(getkeystate((int)key) & key_pressed); } you should know, each time check key state using example iskeydown(keys.a) method returns true if ke...
