sqlcmd — Use the utility

Applies to: SQL Server (all supported versions) Azure SQL Database Azure SQL Managed Instance Azure Synapse Analytics Parallel Data Warehouse

The sqlcmd utility is a command-line utility for ad hoc, interactive execution of Transact-SQL statements and scripts and for automating Transact-SQL scripting tasks. To use sqlcmd interactively, or to build script files to be run using sqlcmd, users must understand Transact-SQL. The sqlcmd utility is typically used in the following ways:

Users enter Transact-SQL statements in a manner similar to working at the command prompt. The results are displayed at the command prompt. To open a Command Prompt window, enter «cmd» in the Windows search box and click Command Prompt to open. At the command prompt, type sqlcmd followed by a list of options that you want. For a complete list of the options that are supported by sqlcmd, see sqlcmd Utility.

Users submit a sqlcmd job either by specifying a single Transact-SQL statement to execute, or by pointing the utility to a text file that contains Transact-SQL statements to execute. The output is usually directed to a text file, but can also be displayed at the command prompt.

Typically used sqlcmd options

Server option (-S) identifies the instance of Microsoft SQL Server to which sqlcmd connects.

Authentication options (-E, -U, and -P) specify the credentials that sqlcmd uses to connect to the instance of SQL Server. NOTE: The option -E is the default and does not need to be specified.

Input options (-Q, -q, and -i) identify the location of the input to sqlcmd.

The output option (-o) specifies the file in which sqlcmd is to put its output.

Connect to the sqlcmd utility

Connecting to a default instance by using Windows Authentication to interactively run Transact-SQL statements:

NOTE: In the previous example, -E is not specified because it is the default and sqlcmd connects to the default instance by using Windows Authentication.

Connecting to a named instance by using Windows Authentication to interactively run Transact-SQL statements:

Connecting to a named instance by using Windows Authentication and specifying input and output files:

Connecting to the default instance on the local computer by using Windows Authentication, executing a query, and having sqlcmd remain running after the query has finished running:

Connecting to the default instance on the local computer by using Windows Authentication, executing a query, directing the output to a file, and having sqlcmd exit after the query has finished running:

Connecting to a named instance using SQL Server Authentication to interactively run Transact-SQL statements, with sqlcmd prompting for a password:

HINT!! To see a list of the options that are supported by the sqlcmd utility run: sqlcmd -? .

Run Transact-SQL statements interactively by using sqlcmd

You can use the sqlcmd utility interactively to execute Transact-SQL statements in a Command Prompt window. To interactively execute Transact-SQL statements by using sqlcmd, run the utility without using the -Q, -q, -Z, or -i options to specify any input files or queries. For example:

When the command is executed without input files or queries, sqlcmd connects to the specified instance of SQL Server and then displays a new line with a 1> followed by a blinking underscore that is named the sqlcmd prompt. The 1 signifies that this is the first line of a Transact-SQL statement, and the sqlcmd prompt is the point at which the Transact-SQL statement will start when you type it in.

At the sqlcmd prompt, you can type both Transact-SQL statements and sqlcmd commands, such as GO and EXIT. Each Transact-SQL statement is put in a buffer called the statement cache. These statements are sent to SQL Server after you type the GO command and press ENTER. To exit sqlcmd, type EXIT or QUIT at the start of a new line.

To clear the statement cache, type :RESET. Typing ^C causes sqlcmd to exit. ^C can also be used to stop the execution of the statement cache after a GO command has been issued.

Transact-SQL statements that are entered in an interactive session can edited by entering the :ED command and the sqlcmd prompt. The editor will open and, after editing the Transact-SQL statement and closing the editor, the revised Transact-SQL statement will appear in the command window. Enter GO to run therevised Transact-SQL statement.

Quoted strings

Characters that are enclosed in quotation marks are used without any additional preprocessing, except that quotations marks can be inserted into a string by entering two consecutive quotation marks. SQL Server treats this character sequence as one quotation mark. (However, the translation occurs in the server.) Scripting variables will not be expanded when they appear within a string.

PRINT «Length: 5″» 7′»;

Here is the result set.

Strings that span multiple lines

sqlcmd supports scripts that have strings that span multiple lines. For example, the following SELECT statement spans multiple lines but is a single string executed when you press the ENTER key after typing GO .

SELECT First line

FROM Second line

WHERE Third line;

Interactive sqlcmd example

This is an example of what you see when you run sqlcmd interactively.

When you open a Command Prompt window, there is one line similar to:

This means the folder C:\ is the current folder, and if you specify a file name, Windows will look for the file in that folder.

Type sqlcmd to connect to the default instance of SQL Server on the local computer, and the contents of the Command Prompt window will be:

This means you have connected to the instance of SQL Server and sqlcmd is now ready to accept Transact-SQL statements and sqlcmd commands. The flashing underscore after the 1> is the sqlcmd prompt that marks the location at which the statements and commands you type will be displayed. Now, type USE AdventureWorks2012 and press ENTER, and then type GO and press ENTER. The contents of the Command Prompt window will be:

Here is the result set.

Changed database context to ‘AdventureWorks2012’.

Pressing ENTER after entering USE AdventureWorks2012 signaled sqlcmd to start a new line. Pressing ENTER, after you type GO, signaled sqlcmd to send the USE AdventureWorks2012 statement to the instance of SQL Server. sqlcmd then returned a message to indicate that the USE statement completed successfully and displayed a new 1> prompt as a signal to enter a new statement or command.

The following example shows what the Command Prompt window contains if you type a SELECT statement, a GO to execute the SELECT , and an EXIT to exit sqlcmd :

SELECT TOP (3) BusinessEntityID, FirstName, LastName

Here is the result set.

BusinessEntityID FirstName LastName

2 Catherine Abel

3 Kim Abercrombie

(3 rows affected)

The lines after line 3> GO are the output of a SELECT statement. After you generate output, sqlcmd resets the sqlcmd prompt and displays 1> . After entering EXIT at line 1> , the Command Prompt window displays the same line it did when you first opened it. This indicates that sqlcmd has exited its session. You can now close the Command Prompt window by typing another EXIT command.

Running Transact-SQL script files using sqlcmd

You can use sqlcmd to execute database script files. Script files are text files that contain a mix of Transact-SQL statements, sqlcmd commands, and scripting variables. For more information about how to script variables, see Use sqlcmd with Scripting Variables. sqlcmd works with the statements, commands, and scripting variables in a script file in a manner similar to how it works with statements and commands that are entered interactively. The main difference is that sqlcmd reads through the input file without pause instead of waiting for a user to enter the statements, commands, and scripting variables.

There are different ways to create database script files:

You can interactively build and debug a set of Transact-SQL statements in SQL Server Management Studio, and then save the contents of the Query window as a script file.

You can create a text file that contains Transact-SQL statements by using a text editor, such as Notepad.

Examples

A. Running a script by using sqlcmd

Start Notepad, and type the following Transact-SQL statements:

SELECT TOP (3) BusinessEntityID, FirstName, LastName

Create a folder named MyFolder and then save the script as the file MyScript.sql in the folder C:\MyFolder . Enter the following at the command prompt to run the script and put the output in MyOutput.txt in MyFolder :

sqlcmd -i C:\MyFolder\MyScript.sql -o C:\MyFolder\MyOutput.txt

When you view the contents of MyOutput.txt in Notepad, you will see the following:

Changed database context to ‘AdventureWorks2012’.

BusinessEntityID FirstName LastName

2 Catherine Abel

3 Kim Abercrombie

(3 rows affected)

B. Using sqlcmd with a dedicated administrative connection

In the following example, sqlcmd is used to connect to a server that has a blocking problem by using the dedicated administrator connection (DAC).

C:\>sqlcmd -S ServerName -A

1> SELECT session_id, blocking_session_id FROM sys.dm_exec_requests WHERE blocking_session_id <> 0;

Here is the result set.

(1 rows affected)

Use sqlcmd to end the blocking process.

C. Using sqlcmd to execute a stored procedure

The following example shows how to execute a stored procedure by using sqlcmd . Create the following stored procedure.

IF OBJECT_ID ( ‘ dbo.ContactEmailAddress, ‘P’ ) IS NOT NULL

DROP PROCEDURE dbo.ContactEmailAddress;

CREATE PROCEDURE dbo.ContactEmailAddress

WHERE FirstName = @FirstName

AND LastName = @LastName;

SET NOCOUNT OFF

At the sqlcmd prompt, enter the following:

1> :Setvar FirstName Gustavo

1> :Setvar LastName Achong

1> EXEC dbo.ContactEmailAddress $(FirstName),$(LastName)

D. Using sqlcmd for database maintenance

The following example shows how to use sqlcmd for a database maintenance task. Create C:\BackupTemplate.sql with the following code.

BACKUP DATABASE [$(db)] TO DISK=’$(bakfile)’;

At the sqlcmd prompt, enter the following:

Sqlcmd: Successfully connected to server .

1> :setvar db msdb

1> :setvar bakfile c:\msdb.bak

1> :r c:\BackupTemplate.sql

Changed database context to ‘master’.

Processed 688 pages for database ‘msdb’, file ‘MSDBData’ on file 2.

Processed 5 pages for database ‘msdb’, file ‘MSDBLog’ on file 2.

BACKUP DATABASE successfully processed 693 pages in 0.725 seconds (7.830 MB/sec)

E. Using sqlcmd to execute code on multiple instances

The following code in a file shows a script that connects to two instances. Notice the GO before the connection to the second instance.

E. Returning XML output

The following example shows how XML output is returned unformatted, in a continuous stream.

C:\>sqlcmd -d AdventureWorks2012

1> SELECT TOP 3 FirstName + ‘ ‘ + LastName + ‘, ‘

2> FROM Person.Person

Syed Abbas, Catherine Abel, Kim Abercrombie,

F. Using sqlcmd in a Windows script file

A sqlcmdcommand such as sqlcmd -i C:\InputFile.txt -o C:\OutputFile.txt, can be executed in a .bat file together with VBScript. In this case, do not use interactive options. sqlcmd must be installed on the computer that is executing the .bat file.

First, create the following four files:

Then, at the command prompt, run C:\windowsscript.bat :

== An error occurred

SQLCMD returned 100 to the command shell

G. Using sqlcmd to set encryption on Azure SQL Database

A sqlcmdcan be executed on a connection to SQL Database data on to specify encryption and certificate trust. Two sqlcmd«options are available:

The -N switch is used by the client to request an encrypted connection. This option is equivalent to the ADO.net option ENCRYPT = true .

The -C switch is used by the client to configure it to implicitly the trust server certificate and not validate it. This option is equivalent to the ADO.net option TRUSTSERVERCERTIFICATE = true .

The SQL Database service does not support all the SET options available on a SQL Server instance. The following options throw an error when the corresponding SET option is set to ON or OFF :

The following SET options do not throw exceptions but cannot be used. They are deprecated:
