If you are using SQL2005 or SQL2008, you can use the SQLCMD.exe utility.

Here's an example:
:setvar DatabaseName "MyDatabase"
GO
USE [$(DatabaseName)]

>I am writing a script that creates my database, stored procedures, tables, user data types etc. The script is over 800 lines and all works perfectly if I hard code the database name on the USE line. Here's the start of it:
>
>-- Create the upower database
>declare @dbname varchar(30)
>declare @sql varchar(200)
>
>set @dbname = 'utestbase'
>set @sql = 'create database ' + @dbname
>
>exec (@sql)
>go
>
>use utestbase
>go
>
>Now, obviously I want to pass in the "utestbase" value or any other value when I run the script. I just can't figure out how to execute the USE command with a variable, i.e. use @dbname.

>I've seen posts on other websites that describe using dynamic sql, as I have done for the create database function. However, it appears that in order to have the USE command in dynamic SQL you have to include the entire script in the batch. I can't do that because, when I try to construct the statement with concatenation, apostrophes just won't work. As you can imagine I have apostrophes all through my code.
