如何在SQL脚本文件中使用参数

Question

我想创建一个带有SQL脚本文件的数据库，但是我不能给出参数而不是数据库名称我该如何解决？

Declare @Test as nvarchar(max)

CREATE DATABASE [@Test] ON  PRIMARY 
  ( NAME = N'@Test', 
    FILENAME = N'C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\DATA\@Test.mdf', 
    SIZE = 11264KB , MAXSIZE = 51200KB , FILEGROWTH = 10%)
 LOG ON 
 ( NAME = N'@Test_log', 
   FILENAME = N'C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\DATA\@Test_1.ldf' , 
   SIZE = 9216KB , MAXSIZE = 25600KB , FILEGROWTH = 1024KB )
GO

ALTER DATABASE [@Test] SET COMPATIBILITY_LEVEL = 100
GO

如果您使用SQLCMD compatibility mode in SQL Server Management Studio，则可以使用SQLCMD参数：

:setvar dbname YourDatabase

CREATE DATABASE $(dbname) ON  PRIMARY 
( NAME = $(dbname), 
  FILENAME = N'C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\DATA\$(dbname).mdf', 
  SIZE = 11264KB , MAXSIZE = 51200KB , FILEGROWTH = 10%)
LOG ON 
 ( NAME = N'$(dbname)_log', 
   FILENAME = N'C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\DATA\$(dbname)_log.ldf' , 
   SIZE = 9216KB , MAXSIZE = 25600KB , FILEGROWTH = 1024KB )
GO

ALTER DATABASE $(dbname) SET COMPATIBILITY_LEVEL = 100
GO

也可以使用命令行上的SQLCMD命令行工具

指定这些参数

您可以在Tools > Options下的SQL Server Management Studio中启用“SQLCMD模式”

此更改仅会影响正在打开的SSMS中的新窗口 - 它不适用于已经打开的窗口。
