Oracle SQL Tutorial 8 - Indexes - Database Design Primer 5
 
11:06
The concept of an index is extremely important when managing a database. An index has the power of making your database very quick or it has the power to bog down your update, delete, and insert statements. The trick is to find a good balance. You will want to index any columns that are used continually in a select or a join. By default, all primary keys are indexed as well as any columns with the UNIQUE column attribute. I suggest you consider adding an index to your foreign keys as these will often be used in joins as well. You can actually create an index on a group of columns. This will allow you to search for data and return multiple columns. This is known as a composite index. There are many other things to database design...much more than we have covered. I have decided I will cover these as we go so that we can start applying what we learn practically.

SQL Server 34 - How to Create and Drop Indexes
 
05:15
Creating indexes is a very easy task, but before you go creating indexes on everything, you need to know that some columns are indexed by default. Specifically, any column that is labeled as the PRIMARY KEY or UNIQUE are indexed by default. That means that if you have a UNIQUE column, you do not need to worry about adding an INDEX to it. The columns that you will want to pay special attention to are any foreign keys or columns that you are going to use very frequently. We are going to create an index on our SpeciesID column in our Animals table. This is a foreign key that I'm likely going to use very frequently. CREATE INDEX IX_AnimalsSpecies ON Animals (SpeciesID); The syntax is very similar to CREATE TABLE in that you say CREATE INDEX followed by an index name. The IX_ is a prefix that is sometimes conventionally used to name indexes. Next, we have the table name, and then we have something to describe the column. That way if you see IX_AnimalsSpecies, you automatically know it is talking about an Index for the Animals table that is on the column dealing with the species. To get rid of this index, use this: DROP INDEX IX_AnimalsSpecies; Which is also very similar to how we drop a table. Now, you can also create an INDEX on multiple columns if you are going to use them together very often. The way you do that is just add another column after a comma inside of the () in the index columns. For example: CREATE INDEX IX_AnmialsContact ON Animals (Name, ContactEmail); One other thing I wanted to show you is that you can actually create a UNIQUE Index by adding the keyword in: CREATE UNIQUE INDEX IX_Species ON Species (Species); This should only be used if every value for a column is labeled unique…In fact, it forces every row to be unique. Remember though that if a column is labeled UNIQUE, it is indexed by default...So this is not needed in this situation. In the next video we will discuss in more detail whether you want to use the UNIQUE Constraint create a UNIQUE index. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

SQL View
 
11:19
SQL is a standard Structured query language for storing, manipulating and retrieving data in databases. View 1) What is a View? A view is a saved SQL query. A view can also be considered as a virtual table. actually retrieves the data from the underlying base tables. vtblEmployee, vtblDepartment Create View vWName as sql query Views can be used to reduce the complexity of the database schema, for non IT users. Views can be used as a mechanism to implement row and column level security. Row Level Security where tblDepartment.DeptName = 'IT' To look at view definition - sp_helptext vWName ; To modify a view - ALTER VIEW statement ; To Drop a view - DROP VIEW vWName. 2) Updateable Views Is it possible to Insert, Update and delete rows, from the underlying tblEmployees table, using view vWEmployeesDataExceptSalary? Yes, SQL server views are updateable. Update vWEmployeesDataExceptSalary Set Name = 'Mikey' Where Id = 2 3) Indexed views when you create an index, on a view, the view gets materialized. This means, the view is now, capable of storing data. In SQL server, we call them Indexed views and in Oracle, Materialized views. vtblProduct , vtblProductSales If you want to create an Index, on a view, the following rules should be followed by the view. For the complete list of all rules, please check MSDN. 1. The view should be created with SchemaBinding option 2. If an Aggregate function in the SELECT LIST, references an expression, and if there is a possibility for that expression to become NULL, then, a replacement value should be specified. In this example, we are using, ISNULL() function, to replace NULL values with ZERO. 3. If GROUP BY is specified, the view select list must contain a COUNT_BIG(*) expression 4. The base tables in the view, should be referenced with 2 part name. In this example, tblProduct and tblProductSales are referenced using dbo.tblProduct and dbo.tblProductSales respectively. Limitation : 1. You cannot pass parameters to a view. Table Valued functions are an excellent replacement for parameterized views. 2.Rules and Defaults cannot be associated with views. 3.The ORDER BY clause is invalid in views unless TOP or FOR XML is also specified. 4.Views cannot be based on temporary tables.
