How to clear data from cache memory

How to clear data from cache memory

data cache

as of 15.0.3 - dbcc cachedataremove(dbid | dbname, objid | objname, partitionid | partitionname, indid | indexname)
you need sa_role for that as well

pre-15.0.2 ESD6 - try sp_unbindcache_all 'default data cache'
for example to clear "default data cache".  For named data caches, you should do this, followed by a sp_bindcache again for each object bound to a named cache
statement cache

set statement_cache off    -- session level
<your sql statements here>
or
sp_configure 'statement cache size',0  -- server level
procedure cache

In 12.5.4 ESD5 and 15.0.2 :   dbcc proc_cache (free_unused)

pre 12.5.4 ESD5:    dbcc proc_cacherm(type, dbname, objname)

where: type is V,P,T,R,D,C,F, or S (must be uppercase) corresponds to View, Proc, Trigger, Rule, Default, Cursor, SQLJ Function, SQL function.
