sql server - SQL extracting information from columns names -


i have sql server table column names such int115, int430 , on corresponding data. want multiply data in int115 column 115, data in int430 column 430 , on. not sure how proceed.

edit: need parse column names , rid of left 3 characters come multiplier number.

edit2: working grandfathered table can't make changes how database looks like.

edit after question updated

this not require hard coding @ all: cursor through temp table parsed through column names multiplication values, select table , give multiplied values. using 'sampletable' table name. assumes each of columns begin int , have number after.

select column_name,      cast(substring(column_name, 4, 10)as int) multiplier_number      #values information_schema.columns table_name = 'sampletable'  declare @ssql nvarchar(max) declare @columnname nvarchar(50)  declare thing cursor             (         select column_name          #values         ) open thing fetch next thing     @columnname  while @@fetch_status = 0 begin     set @ssql = 'select ' + @columnname + '* (select multiplier_number #values column_name = '''+ @columnname+''') '+@columnname+' sampletable'  exec sp_executesql @ssql  fetch next thing @columnname end close thing deallocate thing

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
