Another approach would be to create a .BAT file with the following command:

for %%G in (*.sql) do sqlcmd /S servername /d databaseName -E -i"%%G"
pause

Place this .BAT file in the directory from which you want the .SQL files to be executed, double click the .BAT file and you are done!

参数说明

-S [protocol:]server[instance_name][,port]  

-d db_name  

-E (use trusted connection) 

-i input_file  

-U login_id  

-P password  

错误1

Sqlcmd: Error: Microsoft SQL Server Native Client 11.0 : Login failed. The login is from an untrusted domain and cannot be used with Windows authentication.. 

错误2

加上用户名和密码后提示

Sqlcmd: The -E and the -U/-P options are mutually exclusive.  互斥的

 修正

添加-U和-P，并且去掉-E就可以执行

输出到文件

脚本文件

(1).没有任何参数的for
格式为：for %%i in (set) do command
%%i 为变量
set为一个文件或者一组文件，其实就是一个集合。可用通配符，比如*.txt。
command 是要执行的命令。


看个例子： 当前目录中有如下文件： a.txt b.mp3 c.mp3 c.wma a.rm e.bat

你想显示里面的扩展名为mp3的文件，你会用什么命令呢？当然是dir了，dir *.mp3。 
同样的，for也可以来实现，如下： for %%i in (*.mp3) do echo %%i 这如何理解？
 for会先从括号里面执行，因为括号里面是*.mp3,所以for会先得到当前目录下所有的扩展名是mp3的文件，并把它们作为一个集合，而每个文件名就是一个元素，
像这样{b.mp3，c.mp3}，然后用%%i依次代替每个元素，之后做do后面的命令。

当然，()里面不局限于一个文件或者通配符，可以有多个，比如：
for %%i in (*.mp3,*.wma) do echo %%i   也是可以的。
注意：do 后面可以跟任何命令，不要局限于echo，这里只是演示。
