Sql Server Execute Batch File
In last month I received few emails emails regarding SQL SERVER – Enable xp_cmdshell using sp_configure.
The questions are
1) What is the usage of xp_cmdshell and
2) How to execute BAT file using T-SQL?
- Hello, Am trying to execute a batch / cmd file with dynamic parameter to the batch file using t-sql / xpcmdshell. Basically am trying to execute a robocopy command from t-sql - read somewhere that this is not possible & i hav to wrap my command in batch file.
- I was working on a project where I’m supposed to deploy lots of SQL Server script files (.sql). It’s very tedious job either to manually execute or to write a batch script each time when the deployment moves to another environment.
- There are different options available when you want to execute a.sql script file on a server. You can open the script file in SQL Server Management Studio and execute it, or you can use SQLCMD to execute a script from command line. However, when you have large number of scripts to execute these methods.
I really like the follow up questions of my posts/articles. Answer is xp_cmdshell can execute shell/system command, which includes batch file.

See SQLCMD Utility Documentation 1. You specified the wrong server name in the SQLCMD parameters. If you are not logged onto the same computer as the SQL Server, then you may not be able to use -E (Trusted Connection) and will have to specify the Username and Password using -U and -P parameters. Here is an example of a SQLCMD call from a batch file. It uses a separate.sql file (after the -i), and sends all output to a log file (the file after -o).
EXEC master.xp_CMDShell 'ISQL -L'
2) Example of running batch file using T-SQL
i) Running standalone batch file (without passed parameters)EXEC master.xp_CMDShell 'c:findword.bat'
ii) Running parameterized batch file
DECLARE @PassedVariable VARCHAR(100)
DECLARE @CMDSQL VARCHAR(1000)
SET @PassedVariable = 'SqlAuthority.com'
SET @CMDSQL = 'c:findword.bat' + @PassedVariable
EXEC master.xp_CMDShell @CMDSQL
