------解决方案--------------------
不行,一定要用动态SQL,举个最简单的例子,
SQL code

-- 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'.

------解决方案--------------------
要用动态语句创建库表

------解决方案--------------------
SQL code

-- 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]...)')

------解决方案--------------------
不需要"go", 删除即可.
