Reset sql sa password directly and efficiently


A few days ago, I had a painful experience that I lost SA password on my MS SQL Server database, and I almost took the whole weekend to look for an efficient way to reset SA password. I asked friends, searched on Internet and even bought some book.... Fortunately, I finally got a SQL server password recovery software and it instantly reset SA password without data loss. And I also got a couple of good solutions for sql sa password reset to save your weekend in case you have lost or forgot MS SQL Server passwords (SA password!).



Option 1 : Use MS SQL Server Password Unlocker to Recover/Reset SA Password

The most direct, efficient way to reset SA password is to take use of the third part utility - SQL server password recovery software. Just two steps:

Step 1: Access to master.mdf file, which is default at C:\Program Files\Microsoft SQL Server\MSSQL\Data\master.mdf

Step 2: Select SA password and reset SA password
So, Reset SA password successfully!



Option 2 : Recover or Reset SA Password with Other SQL Server Login
If there is any other SQL Server Login that is a member of sysadmin role, you can log in using that account and reset SA password of SQL Server. Reset sql sa password as described here :

SQL SERVER - Reset Password of SA Login Using Management Studio.

Login into SQL Server using Windows Authentication.

In Object Explorer, open Security folder, open Logins folder. Right Click on
SA account and go to Properties.

Reset SA password, and confirm it. Click OK.

Make sure to restart the SQL Server and all its services and test new password by log into system using SA login and new password.



Option 3 : Recover or Reset SA Password with Windows Login that is a member of Windows Admin Group

If there is any other Windows Login that is a member of Windows Admin Group, log in using that account. Start SQL Server in Single User Mode as described followings :

SQL SERVER - Start SQL Server Instance in Single User Mode.

There are certain situation when user wants to start SQL Server Engine in "single user" mode from the start up.

To start SQL Server in single user mode is very simple procedure as displayed below.

Go to SQL Server Configuration Manager and click on SQL Server 2005 Services. Click on desired SQL Server instance and right click go to properties. On the Advance table enter param '-m;' before existing params in Startup Parameters box.

Make sure that you entered semi-comma after -m. Once that is completed, restart SQL Server services to take this in effect. Once this is done, now you will be only able to connect SQL Server using sqlcmd.

How to write jdbc connections


http://www.jdbc-tutorial.com/

window.google_render_ad();

welcome_title_image.gif Java JDBC Tutorial Java JDBC Tutorial
The JDBC ( Java Database Connectivity) API defines interfaces and classes for writing database applications in Java by making database connections. Using JDBC you can send SQL, PL/SQL statements to almost any relational database. JDBC is a Java API for executing SQL statements and supports basic SQL functionality. It provides RDBMS access by allowing you to embed SQL inside Java code. Because Java can run on a thin client, applets embedded in Web pages can contain downloadable JDBC code to enable remote database access. You will learn how to create a table, insert values into it, query the table, retrieve results, and update the table with the help of a JDBC Program example.


window.google_render_ad();
Although JDBC was designed specifically to provide a Java interface to relational databases, you may find that you need to write Java code to access non-relational databases as well.
JDBC Architecture jdbc.jpg Java application calls the JDBC library. JDBC loads a driver which talks to the database. We can change database engines without changing database code.
JDBC Basics - Java Database Connectivity Steps Before you can create a java jdbc connection to the database, you must first import the
java.sql package.
import java.sql.*; The star ( * ) indicates that all of the classes in the package java.sql are to be imported.
1. Loading a database driver,
In this step of the jdbc connection process, we load the driver class by calling Class.forName() with the Driver class name as an argument. Once loaded, the Driver class creates an instance of itself. A client can connect to Database Server through JDBC Driver. Since most of the Database servers support ODBC driver therefore JDBC-ODBC Bridge driver is commonly used.
The return type of the Class.forName (String ClassName) method is “Class”. Class is a class in
java.lang package.
try { Class.forName(”sun.jdbc.odbc.JdbcOdbcDriver”); //Or any other driver } catch(Exception x){ System.out.println( “Unable to load the driver class!” ); } 2. Creating a oracle jdbc Connection

The JDBC DriverManager class defines objects which can connect Java applications to a JDBC driver. DriverManager is considered the backbone of JDBC architecture. DriverManager class manages the JDBC drivers that are installed on the system. Its getConnection() method is used to establish a connection to a database. It uses a username, password, and a jdbc url to establish a connection to the database and returns a connection object. A jdbc Connection represents a session/connection with a specific database. Within the context of a Connection, SQL, PL/SQL statements are executed and results are returned. An application can have one or more connections with a single database, or it can have many connections with different databases. A Connection object provides metadata i.e. information about the database, tables, and fields. It also contains methods to deal with transactions.
JDBC URL Syntax:: jdbc: <subprotocol>: <subname> JDBC URL Example:: jdbc: <subprotocol>: <subname>•Each driver

Java.sql.SQLException: Network error IOException: Connection refused: connect


Hi,

I too was facing the same problem as mentioned by you and couldn't connect through telnet localhost 1433.
Solution : Just go to SQL server configuration manager----SQL Server Network configuration----Protocols for SQLEXPRESS and in that right click on TCP/IP and in properties field make all TCP/IP port to 1433 which is blank. Start and Restart the SQL server and you can telnet localhost 1433 and it works. Hope this will help.
