Some tips and tricks I used to trace the particles

This post is just MySQL helper to manage my particles in the database.
With help of my best fiend Karine.

What WE DID!!
create procedure proc @snap int
as

select * into #t from MODEL7_test2 where snap between @snap-10 and @snap+10

heto

select ID, MIN( SQRT( POW((a.posx-b.xc),2)+POW((a.posy-b.yc),2)+POW((a.posz-b.zc),2))) as MinPosMax, Max(SQRT( POW((a.posx-b.xc),2)+POW((a.posy-b.yc),2)+POW((a.posz-b.zc),2))) as MaxPos from #t as a
inner join COMDB_MODEL7 as b on a.snap=b.snap
where a.id in (select id from MODEL7_test2 where snap=@snap) group by id;

CREATE TEMPORARY TABLE t1 AS SELECT *
