一、建立資料庫

create database mrkj on primary
(
 name=mrkj_data,
 filename='D:\data2\mrkj.mdf',
 size=5MB,
 MAXSIZE=UNLIMITED,
 FILEGROWTH=10%
)
LOG ON
(
 NAME=MRKJ_LOG,
 FILENAME='D:\data2\mrkj.ldf',
 size=3MB,
 MAXSIZE=50MB,
 FILEGROWTH=2MB
)

二、建立有兩個次要資料庫檔案的資料庫，

create database mingri
on primary
(
  name=mingri1,
  filename='d:\data2\mingri1.mdf',
  size=100mb,
  maxsize=unlimited,
  filegrowth=10mb
),
(
 name=mingri2,
 filename='d:\data2\mingri2.ndf',
 size=80mb,
 maxsize=200mb,
 filegrowth=5mb
),
(
  name=mingri3,
  filename='d:\data2\mingri3.ndf',
  size=20mb,
  maxsize=200mb,
  filegrowth=10%
)
log on
(
 name=mingrilog1,
 filename='d:\data2\mingri1.ldf',
 size=30mb,
 maxsize=50mb,
 filegrowth=1mb
),
(
 name=mingrilog2,
 filename='d:\data\mingrilog2.ldf',
 size=30mb,
 maxsize=50mb,
 filegrowth=1mb 
)

三、給現有資料庫新增次要資料庫

alter database mrkj
add file
(
  name=mrkj,
  filename='d:\data2\mrkj.ndf',
  size=10mb,
  maxsize=100mb,
  filegrowth=2mb
)

四刪除

alter database mingri
remove file mingri3

此處的資料庫名稱不能寫成mingri3.ndf
