sqlserver backup create database

1. Backup the CYZDATA database as the target library 1.bak file and store it in the disk.

use CYZDATA;
backup database CYZDATA to disk='D:\\Desktop\\backup\\目标库1.bak' with format,name='full backup of CYZDATA'

2. Determine whether the table exists in sqlserver, and delete it first if it exists. (The script written in sqlserver is Drop)

IF  EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[测试表]') AND type in (N'U'))
DROP TABLE [dbo].[测试表]
GO

3. Determine whether the database name exists.

use master --切换到master数据库 
go 
if exists(select 1 from sysdatabases where name = 'tour') 
 begin 
 drop database tour 
 end 
 go 

4. Create the database

create database tour 
on ( name = 'tour_mdf', --数据文件逻辑名 
 filename = 'D:\tour.mdf',--数据文件存放路径 
 size = 10MB,--初始大小 
 maxsize = 10MB,--最大大小 
filegrowth = 1MB--增长速度 ) 

5. Create a table stuMarks for the database tour, first determine whether it exists, delete it if it exists, and create it if it does not exist

use tour
if exists(select * from sysobjects where name='stuMarks') drop table stuMarks 
create table  stuMarks 
(ExamNo  varchar(6)  not null  ,  --考号 
stuNo  varchar(6) not null,   --学号 
writtenExam  int  not null,  --笔试成绩 
LabExam  int  not null    --机试成绩 ) 
go
