使用变量中的名称创建数据库

问题描述

我想使用变量中的值创建一个数据库.这是我的脚本，但它不起作用.有任何想法吗?

I would like create a database using value from a variable. Here my script but it does not work. Any ideas?

-- Set Data Base name
DECLARE @DataBaseName char(64);
SET @DataBaseName = 'DbCmsWebsiteTest';

-- Create Data Base
CREATE DATABASE @DataBaseName;
GO

推荐答案

我认为您需要动态 SQL(如果名称是用户提供的，则需要采取适当的预防措施)

You'd need dynamic SQL for this I think (with appropriate precautions if the name is user supplied)

-- Set Data Base name
DECLARE @DataBaseName sysname;
SET @DataBaseName = 'DbCmsWebsiteTest';

IF (@DataBaseName  LIKE '%[^0-9A-Z]%')
    RAISERROR('Invalid Characters in Name, %s',16,1,@DataBaseName)
ELSE
    BEGIN
    SET @DataBaseName = QUOTENAME(@DataBaseName)
    EXEC('CREATE DATABASE '+ @DataBaseName)
    END
