retrieval strategies
Like
If the fetch attribute is set to join, then the Lazy property is ignored
The advantage of an urgent left outer join retrieval strategy is that fewer SELECT statements are used than the immediate retrieval policy.
Agentless latency retrieval requires the enhancement of the byte code of the persisted class to achieve
The list method of Query ignores the urgent left outer connection r

That's great, however, sometimes it's not always an easy road to migrate to 5.6 and even if you're doing so, there's nearly always a time when you want to cont
, the higher the price/performance ratio.7. Better securityMany malicious programs take security products as their targets. Security products must have good self-protection functions, but such self-protection functions are not effective. Once a security product is infected with malicious code, it not only fails to provide protection, but also accelerates the delivery of malicious code. This hidden danger is eliminated in non-proxy mode. Security Virtual Device SVA adopts a dedicated system with
