sql server - Sqlserver group by pending days period -


i have table structure below,

state   application_count   pending_days _________________________________________ tn            10               0 tn            20               1 tn            60               2 tn            10               3 mh            40               1 mh            50               3 mh            20               5 mh            30               8

i want sum application_count based on state , pending_days period. have group pending_days 0 1 days, 1 3 days, morethan 3 days

expected output:

state   application_count    _________________________    tn         30   tn         70   mh         40   mh         50   mh         50

give additional column, group_num using case expression based on condition of pending_days column.

then find sum group group_num , state columns.

query

select t.[state], sum(t.[application_count]) [application_count] from(     select [group_num] = (         case when [pending_days] between 0 , 1 1          when [pending_days] between 2 , 3 2         when [pending_days] > 3 3 else 4 end     ), *      [your_table_name] )t group t.[group_num], t.[state];

find demo here

note:

for pending_days condition, 0 1 days have taken 0 , 1 1 3 days have taken 2 , 3 , morethan 3 days have taken value greater 3.

unity3d - Rotate an object to face an opposite direction -

i have object , b. when click on object b, rotates object b (a faces b). b doesn't face a. need following : when faces b, need face opposite direction. have code rotating @ b. how rotate face opposite direction after that? vector3 targetdirection = target - transform.position; float step = speed * time.deltatime; vector3 newdirection = vector3.rotatetowards (turretdome.transform.forward, targetdirection, step, 0.0f); turretdome.transform.rotation = quaternion.lookrotation (newdirection); you object facing object b, want inverse direction of object after that? objecta.transform.rotation = quaternion.inverse(objecta.transform.rotation) but lets assume example turretdome object a, (negate direction): turretdome.transform.rotation = quaternion.lookrotation (-newdirection); naturally, both of these snippets not show how smoothen rotation, seem know how use time.deltatime. just incase unsure, quaternion.lerp this

angular - Is it possible to get native element for formControl? -

i've got angular2 reactive form . created formcontrol s , assigned input fields by [formcontrol]=... . understand creates nativeelement <-> formcontrol link. my question: possible nativeelement formcontrol ? wanna myformcontrol.nativeelement.focus() i can share 1 terrible solution works me. in reactive forms can use either 1) formcontroldirective ts mycontrol = new formcontrol('') template <input type="text" [formcontrol]="mycontrol"> or 2) formcontrolname ts myform: formgroup; constructor(private fb: formbuilder) {} ngoninit() { this.myform = this.fb.group({ foo: '' }); } template <form [formgroup]="myform"> <input type="text" formcontrolname="foo"> </form> so these directives write patch like 1) formcontroldirective const originformcontrolngonchanges = formcontroldirective.prototype.ngonchanges; formcontroldirective.proto
