如何把sql脚本搞成可以动态生成数据库、表、字段的sql脚本
--创建数据库
create database northwind
on
(name="northwind",
filename="F:\sql2008data\northwind.mdf",
size=3,
maxsize=10,
filegrowth=2%
)
go
create database practice
on
(name="practice",
filename="F:\sql2008data\practice.mdf",
size=3,
maxsize=10,
filegrowth=2%
)
go
--创建数据表
use northwind
create table teachers
([tid] int identity(1,1) not null,
[name] varchar(10),
[age] int,
[address] varchar(50),
[sex] bit,
[tel] int
)
go
create table students
([sid] int identity(1,1) not null,
[name] varchar(10),
[age] int,
[address] varchar(50),
[sex] bit,
[tel] int,
[tid] int
)
go
use practice
create table newstype
(tid int identity(1,1) not null,
tname varchar(10) not null,
tdescription varchar(100)
)
go
create table news
([nid] int identity(1,1) not null,
[name] varchar(50),
[writer] varchar(10),
[time] datetime,
[source] varchar(10),
[content] varchar(8000),
[tid] int
)
go
--创建索引
use northwind
create index i_students_name on students(name)
go
use practice
create index i_news_name on news(name)
go
--添加约束northwind
use northwind
alter table teachers
add constraint PK_tid primary key(tid)

add constraint FK_tid foreign key(tid) references teachers(tid)
--添加约束practice
