Dear Experts,

I have a basic question, please help in understanding.

I understand library cache stores sqls in LRU mechanism,  
whenever a new sql is parsed, SQL will be loaded into library cache and the data block for the sql will be loaded into DB buffer cache.

My question is, will DB buffer cache will contain all the related data for all the sqls stored in library cache?
