sqllite 版本2.7.4以前的版本最大支持2G,以后的最大支持2TB (2000GB)As of version 2.7.4, SQLite can handle databases up to 2^41 bytes (2 terabytes) in size on both Windows and Unix. Older version of SQLite were limited to databases of 2^31 bytes (2 gigabytes). ACCESS最大支持2G,因为微软更希望别人用其昂贵的SQL server。一直以来都把ACCESS的数据库尺寸限制在2G以内。
