Question

使用存储过程在sql server 2005中创建数据库，但数据库名称作为参数传递

Answer 1

查询块下面可能会有所帮助。

DECLARE @Query VARCHAR(MAX)=''
DECLARE @DbName VARCHAR(400) = 'Db1'
DECLARE @DbFilePath VARCHAR(400) = 'E:\Database\'
SET @Query = @Query + 'CREATE DATABASE '+@DbName +' ON  PRIMARY '
SET @Query = @Query + '( NAME = '''+@DbName +''', FILENAME = '''+@DbFilePath+@DbName +'.mdf'' , SIZE = 3072KB , MAXSIZE = UNLIMITED, FILEGROWTH = 1024KB ) '
SET @Query = @Query + ' LOG ON '
SET @Query = @Query + '( NAME = '''+@DbName +'_log'', FILENAME = '''+@DbFilePath+@DbName +'_log.ldf'' , SIZE = 1024KB , MAXSIZE = 2048GB , FILEGROWTH = 10%)'
print @query
exec(@query)

Answer 2

正如bitxwise所说，你需要动态SQL

create proc createdb @dbname sysname
as
declare @sql nvarchar(max)
set @sql = 'create database ' + QUOTENAME(@dbname)
exec (@sql)

这只是最基本的CREATE DATABASE语句。通常在生产环境中，你不会想要这样的过程，即使你这样做 - 你会指定增长，初始大小，位置等。

但这里是参考：http://msdn.microsoft.com/en-us/library/ms176061(v=SQL.90).aspx。

使用 EXEC sp_executesql:

DECLARE @Query NVARCHAR(MAX)
set @Query=''
DECLARE @DbName NVARCHAR(max) = 'Db1'
DECLARE @DbFilePath NVARCHAR(max) = N'E:\Database\'
SET @Query = @Query + 'CREATE DATABASE '+@DbName +' ON  PRIMARY '
SET @Query = @Query + '( NAME = '''+@DbName +''', FILENAME = '''+@DbFilePath+@DbName +'.mdf'' ,  SIZE = 12288KB , MAXSIZE = UNLIMITED, FILEGROWTH = 1024KB ) '
SET @Query = @Query + ' LOG ON '
SET @Query = @Query + '( NAME = '''+@DbName +'_log'', FILENAME = '''+@DbFilePath+@DbName +'_log.ldf'' , SIZE = 32448KB , MAXSIZE = 2048GB , FILEGROWTH = 10%)'
print @query
EXEC sp_executesql @query
