How can I check the SQL server version?
I have recently joined a new company as a database administrator. My first task is to ensure all the servers are running on compatible and updated versions of the SQL server. Therefore I need to verify the version of the SQL server installed on each instance. How can I check the SQL server version?
In the context of SQL, here are the appropriate approaches for checking the SQL server version:-
Method 1 by using the T-SQL query
Firstly, you would need to connect to the SQL server instance using the SQL server management studios or connect with the other client tools.
Now you would need to implement the following T-SQL query:-
“SELECT @VERSION AS ‘SQL Server Version’;”
This above query would help in returning a single string with detailed information about the SQL server including its version name and editions.
Method 2 By using the SQL server management studios
First you would need to open the SQL server management studio.
Now you should connect to the SQL server instance that you want to check.
In the object explorer now right-click on the same server name and then select the properties.
Now you should go to the “general” tab.
Here you can easily see the version that is installed under the product field which would include the SQL server version and edition.
Method 3 by using Java programming language
Firstly you should ensure that you have the Microsoft SQL server JDBS driver installed on your project. Now you can implement this Java code to check the SQL server version along with detailed information:-
Import java.sql.Connection;
Import java.sql.DriverManager;
Import java.sql.ResultSet;
Import java.sql.Statement;Public class SQLServerVersionChecker {
Public static void main(String[] args) {
// Database connection details
String url = “jdbc:sqlserver://:;databaseName=”;
String username = “”;
String password = “”;
Connection connection = null;
Statement statement = null;
ResultSet resultSet = null;
Try { // Load SQL Server JDBC driver Class.forName(“com.microsoft.sqlserver.jdbc.SQLServerDriver”);
// Establish the connection
Connection = DriverManager.getConnection(url, username, password);
// Create a statement
Statement = connection.createStatement();
// Execute the query to get the SQL Server version
String sql = “SELECT @@VERSION”;
resultSet = statement.executeQuery(sql);
// Process the result set
If (resultSet.next()) {
String version = resultSet.getString(1);
System.out.println(“SQL Server Version: “ + version);
}
} catch (Exception e) {
e.printStackTrace();
} finally {
// Clean up resources
Try {
If (resultSet != null) resultSet.close();
If (statement != null) statement.close();
If (connection != null) connection.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}
}
Before running this Java program you should make sure that the SQL server is running and accessible. You can compile and run this Java program. It would print the SQL server version information to the console.
All the above methods would help you in obtaining information about your SQL server version.
