SQL with Oracle 10g XE - Using UPDATE to Change Data in a Table
 
03:16
In this video I use the UPDATE command to change existing data within a table. When using the UPDATE command you also need to use the keyword SET to choose the field column you wish to change and also a WHERE statement to choose the individual record that needs changed. The command I used is: UPDATE BOOKS SET BINDING = 'P' WHERE BOOK_ID = '11'; This video is part of a series of videos with the purpose of learning the SQL language.

Supercharge your Code to Get Optimal Database Performance
 
55:55
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. There he joined the product management team for Oracle Database and server technologies, focusing on developer communities. https://developer.oracle.com/ https://cloud.oracle.com/en_US/tryit

MySQL Tutorial How to use Commit and Rollback TCL in Workbench
 
06:16
In this video we will see How to use commit How to use Rollback. MySQL Workbench is a unified visual tool for database architects, developers, and DBAs. 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.

JDBC Fetch Size - High Performance Java Persistence
 
04:46
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. If you enjoyed this tip, don't forget to subscribe! Till part 3 :) Phil

Transactions and Concurrency Control Patterns by Vlad Mihalcea
 
45:29
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.

MySQL AWS RDS replication to Google Cloud SQL
 
12:47
MySQL AWS RDS Replication to Google Cloud SQL Here is a simple howto guide for how to replicate from AWS RDS to Google Cloud SQL. To setup replication on Google Cloud SQL, we need a static IP address but RDS does not have a static IP address. So for that reason, we need the proxy to forward the traffic from master to slave. There are many different kinds of solutions out there which Bill Schneider already wrote in his blog post. I will go with socat for this test example: socat: e.g., socat TCP-LISTEN,[port],fork,reuseaddr TCP:[hostname]:[port]. Let's get it on! So here is the recipe for our cooking session: Instances: - AWS RDS (Master) - EC2 Instance (Proxy) - Google Cloud SQL (Slave) Before we can start with the replication we need to make the following changes on the RDS Master instance: - Enable backup Backup needs to be enabled for binlog to be enabled or have 1 replication rds instance running. - Setup a new Parameter Group for your RDS Master. We need to enable enforce_gtid_consistency & gtid_mode = ON A reboot is required for this. Now, lets set up a small VM for forwarding a static IP to an RDS hostname. Use a static Elastic IP for making sure that the IP will not change during a reboot Adjust Security Group to make port 3306 wide open. (You can adjust it later to make it more secure) Once you have the instance running you only need to install socat and run following command: $ socat -v TCP-LISTEN:3306,fork TCP:rds-master.c3u5ki2hnnys.eu-central-1.rds.amazonaws.com:3306 That's it! nothing more to do here. Now let us have look on the Google Cloud Replication. Instead of creating a new instance we need to use the migration wizard of google in order to make replication work. Only 3 steps are needed for this procedure: Install the Google Cli SDK on your VM or local machine Create a Google Storage bucket to upload the mysqldump Make a mysqldump of the database and upload it to the storage Then let's run the mysqldump from their master and upload it directly to the Google Storage Bucket: $ mysqldump \ -h3.122.54.17 -P -urdsmaster -p \ - databases aws-rds-master-db \ - hex-blob - skip-triggers - master-data=1 \ - order-by-primary - compact - no-autocommit \ - default-character-set=utf8mb4 - ignore-table \ - single-transaction - set-gtid-purged=on | gzip | gsutil cp - gs://rdsmaster/hq-master1.sql.gz You will find more pieces of information about Google Cloud SQL external replication here. Once this is done we basically only have to go through the Google Cloud SQL Migration process and use the Elastic IP of the EC2 Proxy and the MySQL credentials!

Transaction in MySQL
 
14:38
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

While interacting with Database, use of Transaction is a very helpful approach particularly when the DB interaction involves inserting/updating/fetching data on more than one table structure. A set of DB tasks grouped into a single execution unit is refferd as a Transaction unit. If all the tasks completed successfully then the transaction completes and if one of the tasks fail, then the transaction rolls back.

What is Data? Collection of Information or collection of raw facts 2. What is Database? It is a collection of related data 3. What is DBMS? Database Management System, It has different types, i. Hierarchical Model ii. Network Model iii. Relational Model 4. What is RDBMS? Relational Database Management System, It is exclusively used to establish the relationship between two database objects and it supports; One to One relation One to Many Many to One Many to Many A database object in a relational database is a data structure used to either store or reference data. The most common object is Table, Other objects are indexes, stored procedures, sequences, views and many more. 5. What are the features of RDBMS? i. Data is stored in Tables ii. Intersection of Rows and Columns will give only one value iii. Relation among data is established logically iv. There are no physical links among data v. There is no data redundancy vi. High security for data vii. It supports all type of data (Ex: Numbers, Characters and data images etc…. viii. It supports Null values ix. Supports CODD Rules x. It supports Integrity constants xi. Multiple users can access data from any location 6. What is Record? A Record is nothing but collection of information or data 7. What is Table? Database table consists of Rows and Columns for storing set of records 8. What is SQL? Structured Query Language is used to communicate with a database. According to ANSI (American National Standards Institute., it is the standard language for relational database management systems. 9. What id DDL? SQL has 3 important subsets, i. Data Definition Language (DDL. ii. Data Manipulation Language (DML. iii. Data Control Language (DCL. Data Definition Language, it is a subset of SQL, used to define the database structure. Important DDL Commands are: CREATE - to create objects in the database ALTER - alters the structure of the database DROP - delete objects from the database TRUNCATE - remove all records from a table, including all spaces allocated for the records are removed COMMENT - add comments to the data dictionary RENAME - rename an object 10. What is DML? Data Manipulation Language, It is a subset of SQL, used for managing data within schema objects.
