在Selenuim Automation Test中使用Java连接到MS-SQL服务器

Question

I am trying to connect to MS-SQL server (Microsoft SQL Server 2008 R2) from my Selenium TestNG. I did some research but every where I got the solution for MySQL server. As per my knowledge, there has to be three major difference between coding for MySQL and MS-SQL

[Correct me if I am wrong]

1. Database URL will be

public static String DB_URL = "jdbc:sql://11.22.33.44:1234/DBName"; instead of public static String DB_URL = "jdbc:mysql://11.22.33.44:1234/DBName";

2. Driver String DBClass = "com.sql.jdbc.Driver"; instead of String DBClass = "com.mysql.jdbc.Driver";

3. MS-SQL Jar File

My Question is where can i find MS-SQL Jar file. Also, Am I going correct with above differences?

Answer 1

You may download it from here and add it to your class path. If you are using maven, install it into your local repo using the following command first.

mvn install:install-file -Dfile=sqljdbc4.jar -DgroupId=com.microsoft.sqlserver -DartifactId=sqljdbc4 -Dversion=4.0 -Dpackaging=jar

Then add the maven dependency to your pom file as below, since the jar does not reside in any of the maven central repositories.

<dependency>
    <groupId>com.microsoft.sqlserver</groupId>
    <artifactId>sqljdbc4</artifactId>
    <version>4.0</version>
</dependency>

package dbconnection;

   import org.testng.annotations.Test;
   import org.testng.annotations.AfterClass;
   import org.testng.annotations.BeforeClass;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;

public class DatabaseTesingDemo {
    //Connection object
    static Connection connection;
    //Statement object
    private static Statement statement;
    //Constant for DB URL
    //public static String DB_URL = "jdbc:sqlserver://58.2.92.60:1433/RBL_Feb2016";
    public static String DB_URL = "jdbc:sqlserver://localhost:1433/Ashish practice";
    //DB credential
    public static String userName = "sa";
    public static String password = "atyati@123";

@BeforeClass
public void setUp() throws Exception {
    try {
        System.out.println("Before");
        //Make the DB Connection
        String DBClass = "com.microsoft.sqlserver.jdbc.SQLServerDriver";
        Class.forName(DBClass).newInstance();
        //Get Connection DB
        Connection connection =  DriverManager.getConnection(DB_URL, userName, password);
        //Statement object to send the SQL statement to DB
        statement = connection.createStatement();   

    }catch(Exception e) {
        e.printStackTrace();
    }
}

@Test
public void test() {
    try {
        System.out.println("Executing Test");
        String query = "select * from userinfo where userID='1";
        //Get the content of customer table from DB
        ResultSet resultSet = statement.executeQuery(query);
        //Print the result until all the records are printed
        while(resultSet.next()) {
            System.out.println(resultSet.getString(1));
            System.out.println("\t" + resultSet.getString(2));
        }

    }catch(Exception ee) {
        ee.printStackTrace();           
    }
}

@AfterClass
public void tearDown() throws Exception {
    System.out.println("After");
    //CLose DB Connection
    if(connection != null) {
        connection.close();
    }
}

}

Error log is:

I am using Microsoft SQL Server 2008 R2.

Answer 3

I think your DB name contains a blank space, which would cause the driver to throw this error. Could you please point to a DB which has no blank space characters and let me know how it goes?

"jdbc:sqlserver://localhost:1433/**Ashish practice"**
