红色的部分说是有语法错误 why

create database 后面要加实际的名称,不能用变量.

[--小F--]

用变量创建数据库？

[mustudent]

这个得拼SQL语句吧。

[唐诗三百首]

用要动态SQL,

  exec(@sql)
    
end  

END

我上面的不能用吗

[唐诗三百首]

不行,一定要用动态SQL,举个最简单的例子,

-- 建测试库,正常.
create database abcd

-- 删除测试库,正常.
drop database abcd

-- 用变量做库名,出错.
declare @KuName nvarchar(50)
select @KuName='abcd'
create database @KuName

Msg 102, Level 15, State 1, Line 4
Incorrect syntax near '@KuName'.

要用动态语句创建库表

[xujinli88]

那我想在创建表的同时给这个数据库加一张表 怎么加啊 请您指点

[xujinli88]

是接着上面的代码

[唐诗三百首]

-- 在存储过程中,建完数据库后执行.
exec('use '+@KuName+' create table [表名]([字段名] [数据类型]...)')

[xujinli88]

alter proc P_create
as
declare @year nvarchar(100)
declare @KuName nvarchar(200)
begin
begin transaction
select @year=cast(YEAR(getdate()) as nvarchar),
@KuName='XQ_'+Cast(YEAR(getdate()) as nvarchar(50))

if exists(select * from sys.databases where [name]=@KuName ) --判断该数据是否存在
print '该数据库已经存在'
else
begin
declare @sql varchar(5000)

select @sql='create database '+@KuName+' ON PRIMARY '
+'(name='''+@KuName+''',filename=''D:\Project\DataBase\'+@KuName+'.mdf'', '
+'size=20,filegrowth=10%) log on(name='''+@KuName+'_log'','
+'filename=''D:\Project\DataBase\'+@KuName+'.ldf'',size=20,filegrowth=10%)'
exec(@sql)
declare @sqltable varchar(5000)
select @sqltable=' use '+@KuName+' go '
+' CREATE TABLE [dbo].[TB_RealData]('+
+' [Company_Code] [nchar](30) COLLATE Chinese_PRC_CI_AS NOT NULL,'
+' [Real_Data] [varchar](800) COLLATE Chinese_PRC_CI_AS NOT NULL,'
+' [Real_Date] [datetime] NULL,'
+' [Real_Type] [varchar](2) COLLATE Chinese_PRC_CI_AS NULL,'
+' [Real_Remark] [varchar](100) COLLATE Chinese_PRC_CI_AS NULL'
+' ) ON [PRIMARY]'
exec(@sqltable)
end
commit transaction /*提交事务*/
end
这个地方有错误 ？

[唐诗三百首]

不需要"go", 删除即可.

请看10楼代码.

谢谢哦 明白了
