sql - Transpose Columns to Rows - Teradata -


i have 2 tables following data

tablea types   columna columnb columnc dart    8.00     9.00   10.00  tableb types  descp    acnt dart  columna 14000 dart  columnb 15000 dart  columnc 16000

my expected output 

types amt   acnt dart 8.00  14000 dart 9.00  15000 dart 10.00 16000

i have written following code output

 select x.types,  case when descp='columna' columna  when descp='columnb' columnb   when descp='columnc' columnc else null end amt,  b.acnt     tablea x  join  tableb y  on  x.types=y.types

these sample data , there around 10 types , more 10 columns. there other option apart writing case statements including columns achieve this? thanks

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
