Welcome back to another tutorial on Java JDBC, In this video, we'll learn how to use transactions with JDBC. We will first define what transactions are, then we'll learn how to develop transactions with JDBC. For this tutorial, we'll use the following table: employees. The table also has sample data for testing. I have a SQL script that will create the table and add sample data for you. You can download it from the link below. Time - 00:32 A transaction is basically a unit of work. You can execute multiple statements together. Based on your application if everything is okay, all of those statements are executed together. This is known as a commit. If there's a problem then none of the statements are executed. This is known as a rollback. In the diagram, if it is okay to save then we commit the statements to the database. If it is not okay to save then we rollback, effectively throwing away the changes. Time - 00:58 By default auto commit is set to "true". You have to explicitly turn it off to set auto commit to "false". At this point the developer controls the commit and rollback. This is very straightforward. If you want to commit, then you call the commit method. Likewise if you want to rollback, then you call the rollback method. That's it. Time - 01:17 Let's look at this with a code snippet. At the beginning, we set auto commit to false. Then we can perform multiple SQL statements like insert, updates and deletes. Next we can ask the user if it's okay to save. This is simply a call to the helper method that would get input from the user. It returns a Boolean value of true or false. Then if okay we commit, else we rollback. Time - 01:40 Let's switch over to Eclipse and see this in action. I have a simple Java program called Transaction Demo. For the transaction in this example we're going to do the following: the first thing we're going to do is delete all HR employees and then we'll update the Engineering salaries to $300,000. Pretty funny LOL. Let's walk through the code. The first thing we'll do is we’ll go through and get a connection to the database, we will turn off auto commit by setting it to false. Then just for sanity's sake, we're going to have a, make use of a helper routine called shell salaries and it's going to print up the salaries for the HR and the Engineering departments. It will actually connect to the database and perform a query and get those results accordingly and display them. Time - 02:24 Then we move into our actual transaction part of it. For our first transaction step we're going to execute an update. In this case we're going to actually do a delete from employees where department equals HR. This is where we delete all HR employees. Then we'll move to the next transaction step and we'll actually set the salaries to $300,000 for all Engineering employees. Nice feature. Time - 02:46 Then we'll tell the user the transaction steps are ready and then we're going to prompt the user if it's okay to save. This is just a little simple helper method that's just going to read the user input. If the user enters "yes" it's going to return "true", if the user enters anything else like "no" it will return false. If it's okay then we will commit the data in the database and we'll print out "transaction committed", else we'll rollback the information. Also, finally as another sanity check we'll print the salaries after this step of code, so we'll print out the information for HR and for Engineering. Time - 03:24 I just ran the application and we'll just go look at the output here. At the beginning we display the salaries before, so information for the HR department and also the salaries for the Engineering department. It tells us that the transaction steps are ready, is it okay to save, yes or no? At this point I'm going to say "no" and I'll hit enter. Then it's going to go through and it’s going to tell us "Hey the transactions were rolled back" and also as a sanity sake, they're going to display the salaries after. Time - 03:55 Here's information for HR so we know we the transaction didn't execute because we were trying to delete HR employees but they're still here in our database. A similar thing here for engineering where we're trying to increase all the salaries to $300,000 but again that's not their original values so we know that the transaction was rolled back successfully.

JDBC Fetch Size - High Performance Java Persistence
In this episode I explain the importance of understanding JDBC fetch size and how tweaking this value can improve your queries and persistence layer performance. If the default JDBC fetch size is 50 (each database driver is different), and your select matches 103 rows, the first 50 of them rows will be returned to client, then when the JDBC resultset cursor calls next on to get 51, the java application will call over to the database and retrieve rows 51-100. And similiarly 101-103. This can degrade performance as you are introducing additional latency by calling the database over the network behind the scenes. Most java developers are not aware of this. JDBC provides the ability to change to fetchsize (auto-commit must also be set to false). In this case if we set it to 500, then all rows would be returned (103) and we would remove two network calls to the database for the query above. PostgreSQL by default returns all rows from the query. This is different for each database, so you will need to look at your database and Java Driver reference guide before tuning this flag.

75 Advanced Java Tutorial |JDBC | Batch Processing | Java Database Connectivity | adv java
Advanced Java Java Tutorial: adv java: #Batch Processing: Java Database Connectivity: Instead of sending multiple queries as individual / seperate/one by one query to database software by using network for multile times, its recommended to combine them (all queries) into single batch/unit and send that batch to DataBase once for execution this is called as batch processing. - This reduce network round trips between java application & DataBase s/w. Example. if there are 10 queries to send the queries to database software instead of sending them individually or seperately for 10 times by having 10 n/w roundtrips with browser window or java application, its recommended to combine them into single unit/batch and send that batch to database only for 1 time. - We can not add select sql queries to the batch of batch processing. sample code for batch processing. --------------------------------- Statement st=con.createStatement(); // add queries to batch st.addBatch("insert into student values (674,"ajay","mumbai"); st.addBatch("update student set sadd="hyd" where sno=200"); st.addBatch("delete from student where sno=300"); . . . //Execute the batch int res[]=st.executeBatch(); //{2,3,5}; //process the result int sum=0; for(i=0;i less than res.length;++i) { sum=sum+res[i]; } System.out.println("No of record that are affected "+sum); --Batch processing does not execute queries by default applying do everything or nothing principle for this we need to write additional logic (Ex. A transaction management withdraw and deposite) -In Batch processing java application send queries to database as a batch, similarly query result is come back to application as a batch. -All non-select query execution gives the numeric result (insert, update, delete). A select query execution gives ResultSet object.executeBatch(-) method return type is int[](Array) and it cannot stored ResultSet object, so we cannot add select query to Batch. -The process of combining related/simliar/common operation into single unit/batch and executing them by applying do everything and nothing principle is called as transaction management. -Batch processing does not perform transaction management on its own. But we can bring that effect/logic on batch processing by disabling autocommit mode and by writing additional logic using con.commit(), con.rollback(). Ex. Java JDBC application on batch processing a with transaction management support : =====================================================

MySQL Workbench provides data modeling, SQL development, and comprehensive administration tools for server configuration, user administration, backup, and much more. MySQL Workbench is available on Windows, Linux and Mac OS X. COMMIT: Commit statement commits the current transaction, which means making the changes permanent. A transaction may involve update and or delete and or insert statements. ROLLBACK: Rollback statement rolls back the present transaction, which means cancelling a transaction’s changes.

Supercharge your Code to Get Optimal Database Performance
Everybody agrees that programming languages are lightning-fast and powerful. Yet performance quickly hits a bottleneck when a database is part of the stack. For years and years, databases have been seen as the slow, monolithic back ends that limit your application's throughput. Yet the reality is that most of the time, it is the code interacting with the database that limits your throughput. Autocommit, parallelization at the wrong level, and too many network round-trips are some of the culprits that will limit your throughput. Yet all of those can easily be avoided with some simple tricks and refactoring of your code. In this session, learn how to apply tricks that will supercharge your application. Never wait for a reply from your DBA again. Gerald Venzl is senior principal product manager for Oracle server technologies. He started his career in IT during the dot-com era as a PL/SQL developer using Oracle 8.1.5. Soon after, Gerald specialized in Oracle Database performance tuning before he evolved his role to performance tuning in general, mainly working on the J2EE and Oracle Database stack. Gerald has worked in Austria, New York City, and London; he has since moved to Oracle’s Silicon Valley headquarters.

82 Advanced Java Tutorial | JDBC | Savepoint | Java Database Connectivity | adv java
Advanced Java Tutorial JDBC: adv java : Savepoint How to perform savepoint operation in JDBC? SavePoint: (Feature of JDBC 3.0) Understanding the need of Savepoint: ---------------------------------- Senario 1: --------- Begin Transaction operation 1 operation 2 ....... operation n commit; Transaction All operations will be committed in Database software. Senario 2: --------- Begin Transaction operation 1 operation 2 ....... operation n Rollback Transaction All operations will be rolled back in Database software. Senario 3: --------- Begin Transaction operation 1 operation 2 savepoint (p) Operation 3............ operation n Rollback from (p) Operation 1, Operation 2 will be commited and operation 3 will be roll back in Database software. Savepoint is logical position in a transactions upto which we can roll back the transaction. When save point is placed in the middle of the transactions the logic placed before savepoint will be commited/saved & logics placed after save point will rolled back. There are two types of savepoint: 1) named savepoint 2) Un-named savepoint (The underlaying database software generates id for this savepoint dynamically) Savepoint object means its the object of a java class given by JDBC driver that implements java.sql.SavePoint interface. When savepoint placed in the transaction we can not refrernce it from con.commit(-) method but it can be referenced from con.rollback(-) method. That means we can commit upto savepoint position, but we can roll back upto savepoint position. Ex: Java JDBC working with savepoint to perform both commit & rollback operations in a single transactions. =================================================================== import java.sql.*; public class SavePointTest { public static void main(String[] args) throws Exception { //create the connection object Class.forName("oracle.jdbc.driver.OracleDriver"); Connection con=DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:orcl", "scott", "boss"); Statement st=con.createStatement(); //begin Transaction con.setAutoCommit(false); //operation 1 st.executeUpdate("insert into student values(9976,'yogesh','abad')"); //op1 st.executeUpdate("insert into student values(9978,'bhosle','Omerga')");//op2 //create named savepoint Savepoint sp=con.setSavepoint("mysp"); ////op3 st.executeUpdate("update student set sname='patil' where sno=217"); ////op4 st.executeUpdate("delete from student where sno=456"); //rollback upto savepoint mysp con.rollback(sp); //commit con.commit();//op1,op2 will be commited & op3 , op 4 will be rolled back } }

Transactions and Concurrency Control Patterns by Vlad Mihalcea
Transactions and Concurrency Control are very of paramount importance when it comes to enterprise systems data integrity. However, this topic is very tough since you have to understand the inner workings of the database system, its concurrency control design choices (e.g. 2PL, MVCC), transaction isolation levels and locking schemes. In this presentation, I'm going to explain what data anomalies can happen depending on the transaction isolation level, with references to Oracle, SQL Server, PostgreSQL, and MySQL. I will also demonstrate that database transactions are not enough, especially for multi-request web flows. For this reason, I'm going to present multiple application-level transaction patterns based on both optimistic and pessimistic locking mechanisms.

Transaction in MySQL
This is the eighth screen-cast in the 'Getting Started with MySQL' series. In this video we take a look at the Transaction capabilities of InnoDB Storage Engine. We learn by doing, how a number of MySQL statements can be combined to be executed as a single Unit. We learn about how to commit explicitly in MySQL, how to Rollback, and Rollback to a specific savepoint. Further we take a look at how MySQL solves three of the common problems in Transactions: Dirty Read, Non-Repeatable Read and Phantom Read. This is by studying the importance of a MySQL variable named 'tx_isolation' whose value (READ-UNCOMMITTED/READ-COMMITTED/REPEATABLE-READ/SERIALIZABLE) decides how the changes made by another Transaction on an InnoDB Table gets displayed within a Transaction on the same Table

Database Applications with JDBC •Describe the interfaces that make up the core of the test JDBC API (including the Driver, Connection, Statement, and ResultSet interfaces and their relationship to provider exam implementations) for 1Z0-805 •Identify the components required to connect to a questions database using the DriverManager class (including the jdbc URL) •Construct and use RowSet objects using the RowSetProvider exam class and the RowSetFactory interface •Use JDBC transactions (including disabling auto-commit mode, committing and rolling back transactions, and setting and rolling back to savepoints) for 1Z0-805 •Submit queries and read results from the database (including creating test statements, returning result sets, iterating through the results, and properly closing result sets, statements, questions and connections) •Create and use PreparedStatement and CallableStatement objects 4. Concurrency •Identify code that may not execute test correctly in a multi-threaded environment. •Use collections from the java.util.concurrent exam package with a focus on the advantages over and differences from the traditional java.util collections for 1Z0-805. •Use Lock, ReadWriteLock, and ReentrantLock Questions classes in the java.util.concurrent.locks package to support lock-free thread-safe programming on single variables. •Use Executor, ExecutorService, Executors, Callable, and test Future to execute tasks using thread pools. •Use the parallel Fork/Join Framework 5. Localization •Describe the advantages of localizing an application •Define a locale using exam language and country codes •Read and set the locale with a Locale object •Build a resource bundle questions for a locale for 1Z0-805 •Call a resource bundle from an application •Format dates, numbers, and currency test values for localization with the NumberFormat and DateFormat classes (including number format patterns) 6. Java File I/O (NIO.2) •Operate on file and directory exam paths with the Path class •Check, delete, copy, or move a file or directory with the Files class •Read and change file and directory questions attributes, focusing on the BasicFileAttributes, DosFileAttributes, and PosixFileAttributes interfaces for 1Z0-805 •Recursively access a directory tree using the DirectoryStream and FileVisitor interfaces •Find a file with the PathMatcher test interface •Watch a directory exam for changes with the Watch Service questions interface
