remove mobs from game

i want to remove all mobs spawn from server by use this query

USE SRO_VT_SHARD
UPDATE Tab_RefNest SET dwmaxtotalcount=dwmaxtotalcount*1

what is the right one ?

that query will return nothing since every number * 1 = same number :)
To remove them all just delete this mobs from refnest with delete from _refnest but this will delete all mobs.
