Deferrable keyword in SQL. This is used where we need to invalidate referential integrity between two tables while inserting the data. By using this keyword, the integrity check can be made at the time of committing the transaction. Please visit : www.oracleadda.com and post any queries related to Oracle. Will reply you back at earliest. Thank You

Oracle SQL Tutorial 12 - Intro to Constraints
 
06:13
As I believe I've mentioned in an earlier video, a constraint is basically a rule we can put in our database that prevents someone from putting the wrong data in. It protects our relationships and data integrity. Because the goal of these constraints are to protect our data integrity, you may hear them called integrity constraints. There are many integrity constraints we are going to talk about: NOT NULL UNIQUE PRIMARY KEY FOREIGN KRY CHECK There is also the DEFAULT attribute. These are all keywords we can add to our columns that will change the way the database works with our data and also prevents incorrect data. NOT NULL is a constraint you can put on a column that prevents nulls. A null is the absence of a value. When we say null, we are saying that every single row has to have a value for this column. UNIQUE is a constraint that makes every row have a unique value for this column. Now note, this does not require values to be put it, and it will allow multiple rows to be null. Next, we are going to talk about primary keys. What qualifies a column as a candidate key? First, not a single row should have a null for that column. Second, every row must be unique. The primary key constraint is essentially a combination of the NOT NULL constraint and the UNIQUE constraint. The foreign key constraint sets the requirement that any value in this column for any row must match a row in another column. Check constraints allow us to be more strict with what data is allowed in our database. NOT NULL and UNIQUE give some level of restriction, but what if we want something more specific? For example, what if we only want values between 0 and 100? That is where check constraints come in. When using check constraints, you give a boolean expression. A boolean expression is something that can be evaluated to true or false. It will only insert the row if the value you try to put into the row makes the expression evaluate to true. So if you put in a value too great or small, the expression will be false and the data is not allowed to be entered. The default constraint is a value you can give a column, and if for any reason when the row is created in the table a value is not provided, the default value will be given. So for example, we could have a bank account table where the balance defaults to 0. How do you actually implement these constraints when you are creating a table? In the next video we are going to be adding these to our users table.

44. Unique Constraint in Oracle
 
02:44
In this video you will learn about Unique Constraint in Oracle. The UNIQUE constraint uniquely identifies each record in a database table. The UNIQUE and PRIMARY KEY constraints both provide a guarantee for uniqueness for a column or set of columns. A PRIMARY KEY constraint automatically has a UNIQUE constraint defined on it. Note that you can have many UNIQUE constraints per table, but only one PRIMARY KEY constraint per table.

Course Description – sql2 COURSE DESCRIPTION: Introduction to Oracle9i: SQL consists of two modules, Introduction to Oracle9i: SQL Basics andOracle9i: Advanced SQL. Introduction to Oracle9i: SQL Basics covers creating database structures and storing, retrieving, and manipulating data in a relational database. Oracle9i: Advanced SQL covers advanced SELECT statements, Oracle SQL and iSQL*Plus Reporting.For people who have worked with other relational databases and have knowledge of SQL, another course, called Introduction to Oracle9i for Experienced SQL Users is offered. This course covers the SQL statements that are not part of ANSI SQL but are specific to Oracle.   The Oracle server extends the data modeling capabilities to support an object relational database model that brings object-oriented programming, complex data types, complex business objects, and full compatibility with the relational world. It includes several features for improved performance and functionality of online transactionprocessing (OLTP) applications, such as better sharing of run-time data structures, larger buffer caches, and deferrable constraints. Data warehouse applications will benefit from enhancements such as parallel execution of insert, update, and delete operations; partitioning; and parallel-aware query optimization. COURSE OBJECTIVES: in this course In Oracle9i, you can include the time zone in your date and time data, and provide support for fractional seconds. Three new data types are added to DATE: TIMESTAMP TIMESTAMP WITH TIME ZONE (TSTZ) TIMESTAMP WITH LOCAL TIME ZONE (TSLTZ) Oracle9i provides daylight savings support for datetime data types in the server Create, maintain, and use sequences Create and maintain indexes Create private and public synonyms WHO SHOULD ATTEND?   COURSE OUTLINE:   Creating Views Other Database Objects Controlling User Access SQL Workshop Using SET Operators Oracle9i Datetime Functions Enhancements to the GROUP BY Clause Advanced Subqueries Hierarchical Retrieval Oracle9i Extensions to DML and DDL Statements

JSR 331: Constraint Programming API became an official JCP standard in March 2012. This session describes major constraint programming concepts and demonstrates them with practical examples of scheduling, resource allocation, configuration, and other constraint satisfaction and optimization problems. It also shows how OpenRules uses JSR 331 as an optimization component of its open source decision management system. Copyright © 2013 Oracle and/or its affiliates.
