假设你创建一个数据库时，指定其初始化大小（SIZE ）非常大。例如，如下测试案例所示
USE [master]
GO
CREATE DATABASE [TEST] ON PRIMARY
( NAME = N'TEST_Data', FILENAME = N'D:\SQL_DATA\TEST_Data.mdf' , SIZE = 11527027KB , MAXSIZE = UNLIMITED, FILEGROWTH = 102400KB )
LOG ON
( NAME = N'TEST_log', FILENAME = N'D:\SQL_LOG\TEST_log.ldf' , SIZE = 40350KB , MAXSIZE = 2048GB , FILEGROWTH = 32768KB )
GO
