After you add the new record into table A, you can use the LAST_INSERT_ID() function to retrieve the value of the auto_increment PK field. Look here for more information on this function: http://dev.mysql.com/doc/refman/5.0/en/information-functions.html

How to fix mySQL corrupt databases?


you should follow two steps:

Create an appropriately named database on the target machine
Load the file using the mysql command:
$ mysql -u [uname] -p[pass] [db_to_restore] < [backupfile.sql]
Have a look how you can restore your tut_backup.sql file to the Tutorials database.
$ mysql -u root -p Tutorials < tut_backup.sql
To restore compressed backup files you can do the following:
gunzip < [backupfile.sql.gz] ' mysql -u [uname] -p[pass] [dbname]
If you need to restore a database that already exists, you'll need to use mysqlimport
command. The syntax for mysqlimport is as follows:
mysqlimport -u [uname] -p[pass] [dbname] [backupfile.sql]

Or make use of Repair Toolbox for MySQL

Php counter


You might want to note that this is not the most effective manner of creating a counter in PHP. On a few of my websites, I find it is much more effective to simply create a text file, eg. counter.txt and have PHP read that every time the page is loaded, instead of running a MySQL query. Then, have PHP also update the counter.txt file by adding 1 to the number already listed in the file and read to the user.

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

I can't connect the ms-sql database with flex


It sounds like you don't have the proper authentication to access the SQL server from the error code you are receiving. I would ask you SQL DBA to check on the permissions within SQL and verify that you have the proper access rights to the database you are connecting too. It is SQL throwing that exception error...

Steps and definition of ReOrganizing mysql Database


I can't really tell what you mean by "re-organizing" a database. Some things this could include are:

  • Creating new tables
  • Deleting unused tables
  • Changing the structure of the database's tables (adding fields, removing fields, moving fields between tables, etc.)
