SQLCMD command line Utility is an alternative way to execute SQL scripts using the command line. This allows us to execute SQL scripts without touching SQL Server Management Studio (SSMS) GUI.
The command line has multiple advantages in certain circumstances. Frequently, this process will save your time and mouse clicks. Plus, it is frequently used to run the same files on multiple sql servers with ease.
To follow along with my example, copy the following code and save it as CreateDBCompany.sql file under the C:\Sqlscripts\ folder.
USE Master
GO
IF EXISTS ( SELECT [name] FROM sys.databases WHERE [name] = 'DBCompany' )
DROP DATABASE DBCompany
GO
CREATE DATABASE DBCompany
GO
USE DBCompany
GO
IF EXISTS ( SELECT [name] FROM sys.tables where [name]='Employee' )
DROP TABLE Employee
GO
CREATE TABLE Employee
(
EmpId int,
Fname varchar(40),
Lname varchar(40),
Hiredate datetime,
Salary int
)
GO
INSERT INTO EMPLOYEE VALUES (101,'Vishwanath','Dalvi','10/16/2011',23025);
Using the sqlcmd command
Now that our example is set, we will execute the CreateDBCompany.sql script file using SQLCMD command line.
1. Click Run and type the letters CMD. Hit OK, and a command prompt window will appear.
2. Now, locate the directory C:\sqlscripts\ using the following commands:
• Change the directory to C drive using cd c:\.
• Go to the folder by typing cd followed by a space, and then sqlscripts folder name such as cd sqlscripts.
• See the sqlscripts directory contents using dir. You can see our CreateDBCompany.sql file.
3. Here, we are using SQLCMD to connect to your local sql server database. Through this same process you may connect to any remote sql server on your network.
SQLCMD -S DALVI2\SQLSERVER2012 -E -i CreateDBCompany.sql
The -S switch is for the Server name and is the same one we use to connect using SSMS GUI. Connect to server option. In my case, it is DALVI2\SQLSERVER2012.
The -E switch is used for trusted connection.
The -i switch is for .sql script file name.
All switches are case sensitive. For more help on SQLCMD Utility switches, use the sqlcmd /? command.
You should now be able to go to SSMS and query the DBCompany database. You will see the employee table with the one record that we had previously created.
