SQL Server 33 - Indexes
 
07:42
Indexes allow us to tell the database that certain columns are columns we want to retrieve commonly. This allows the database to optimize retrieval. Additionally, when we get into the SELECT statement, we will often have to join data from multiple tables. When we correctly add indexes to our tables, we can improve the speed of our SELECT and also our joins. There are two types of Index. One is called clustered and the other is called non-clustered. Clustered indexes determine the actual order of the table. By default this is going to be the primary key column. So when you label a column as PRIMARY KEY, you are also going to be creating an INDEX that is a clustered index. A clustered index is kind of like a telephone book, where the data is right there when you look up a phone number. This means that if you are just making a small database that is only going to store a few things, you may be fine. But more likely than not you are going to want to add additional indexes. When you add a new index, you create a non-clustered index. These things do not actually determine the order of the rows in the table. A way of how you can think of how these work is like an index in the back of a book. The index of the book does not actually contain the data, it just tells you where to find it. What columns do you index? You are going to want every primary key to be indexed. What about foreign keys, are they indexed by default? No, they are not. Of all columns, you are probably going to want to index the foreign keys the most because they are used in joins. Lastly, you will likely want to index columns that you are going to use on a regular basis. You can also make composite indexes just like you can make composite keys. You would want to do this when you are going to constantly being using those columns together. There is a lot to learn on multicolumn indexes. We may explore this concept in more detail and see how SQL Server uses them in a future video, but as of right now it's probably more important that we get a general understanding of all things SQL Server before we deep dive on something like that. In the upcoming videos I'll be teaching you how to create indexes. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 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 with Oracle 10g XE - Using LIKE for Wildcards with SELECT
 
05:02
In this video I use the LIKE command rather than an equals sign to place a condition on my query to allow the use of wildcards within my criteria. When using SQL with Oracle you will need to use the percent sign as the "all characters" wildcard. I perform several queries using the wildcard as describe the results. This video is part of a series of videos with the purpose of learning the SQL language. For more information visit Lecture Snippets at http://lecturesnippets.com.

A Story of Indexes and Full Table Scans: Finding All the Red Sweets Part 1
 
08:43
"Why isn't Oracle using my index?!" is a common question people have when tuning SQL queries. In this episode Chris compares two methods for finding all the red candies from party bags he's prepared. He shows how these are like a full table scan and an index range scan. He goes on to compare the performance of these two approaches. He shows when a full table scan becomes more efficient than an index range scan and vice versa. ============================ The Magic of SQL with Chris Saxon Copyright © 2015 Oracle and/or its affiliates.

Oracle 12c Database New Features - Pluggable Database - Video 1
 
17:25
Oracle 12c Database New Features - Pluggable Database - Video 1 1. Pluggable Database * Oracle 12c introduces a new feature called 'Pluggable Database'. Here Oracle Metadata and user data are totally separated into two sections. One is Container DB (or CDB) which will hold Oracle Metadata. The other is Pluggable DB (or PDB) which will hold user data. How does a Pluggable Database work? In the regular database, Oracle's metadata and user's application data are integrated. For beginners, Oracle Metadata is the data that is present when you install a new Oracle Database (without any sample schemas). Even though it can be called as an empty database, it still has data provided by Oracle. This data is needed by the database to function. For example, the objects owned by SYS, SYSTEM are mostly metadata. Then user data is entered into that database. They will go under multiple user schemas. Now the database is being used by the users. Now a situation arises so that we need to create another database on the same server. Why? Let us say that you need to provide data to two clients. And you don't want one client to other's data. And your data is contained in an extensive set of application schemas. In this case, making a copy of those applications schemas into a different set of names and making them reside in the same database is very difficult. So, you provide two separate databases. This also ensures that there is no security violation. So, we install another new database, which comes with Oracle Metadata. Then we load the user data. In this method, which is currently being used (Year 2013), there will be a need for more memory for both the database instances. There will be two SGAs, two sets of smon, pmon and other background processes running. Then if we need to copy one database to another, we need to rely on extensive procedures which includes exporting the data from the source database first, then removing the data at the target and then finally loading the data in there. After that, we need to take care of the user security and object privileges etc. So, if you want to provide data for multiple tenants, that is multiple clients, then with the current set of features (till Oracle 11g), we have to create multiple databases. That is, one database for one client. In otherwords, there is no multi-tenancy. Multi-Tenancy is becoming an important requirement in cloud infrastructure, these days. You would like to have the ability of providing data to multiple clients from the same database system with full confidence in security. This can be achieved in Pluggable Database. In a Pluggable Database, Oracle basically separates its metadata entirely from the user data. Metadata is stored in a section called Container DB. Then the user data are stored in Pluggable DBs. It also stores user metadata in the Pluggable DB. By the way, what is user metadata? For example, earlier, the list of user accounts that exist in a database is tightly inegrated with Oracle Metadata. Now, with the separation of Container DB and Pluggable DB, the user accounts must exist in the Pluggable DB. So, the Pluggable DB not only contains user data, but also some user metadata. So, what are the benefits? * Multi-Tenancy - We can bring in two Pluggable DBs under one Container DB. Both will be totally segregated, but yet controlled by one instance. This is an important feature for SaaS (Software as a Service) platforms, Cloud, On-Demand and Vendor Managed Application solutions. * Easy cloning/copying. Now the cloning and copying the databases across servers would be much easier. Just clone a Pluggable DB and plug-it-in in a different server. * Very easy upgrades and patching.

mysql tutorial for beginners (6/8) : Indexes
 
05:48
mysql tutorial for beginners (6/8) : Indexes As things stand, the table students works and can be searched without problem by MySQL—until it grows to more than a couple of hundred rows, At that point, database accesses will get slower and slower with every new row added, because MySQL has to search through every row whenever a query is issued. This is like searching through every book in a library whenever you need to look something up. Of course, you don’t have to search libraries that way, because they have either a card index system or, most likely, a database of their own. The way to achieve fast searches is to add an index, either when creating a table or at any time afterward. But the decision is not so simple. For example, there are different index types such as a regular INDEX, PRIMARY KEY, and FULLTEXT. Also, you must decide which columns require an index, a judgment that requires you to predict whether you will be searching any of the data in that column. And even when you’ve decided that, you still have the option of reducing index size by limiting the amount of each column to be indexed. If we imagine the searches that may be made on the students table, it becomes apparent that all of the columns may need to be searched. Anyway, go ahead and add an index to each of the columns, using the commands: ALTER TABLE students ADD INDEX(name(3)); An alternative to using ALTER TABLE to add an index is to use the CREATE INDEX command. They are equivalent, except that CREATE INDEX cannot be used for creating a PRIMARY KEY CREATE INDEX surname ON students (surname(5)); DESCRIBE students; These commands create indexes on both the name and surname columns, limiting name index to only the first 3 characters, and surname index to the first 5 characters. For instance, when MySQL indexes the following name: SAFAA It will actually store in the index only the first 3 characters: SAF This is done to minimize the size of the index, and to optimize database access speed. DESCRIBE command shows the key MUL for each column. This key means that multiple occurrences of a value may occur within that column, which is exactly what we want, as name or surname may appear many times. You don’t have to wait, until after creating a table to add indexes. In fact, doing so can be time-consuming, as adding an index to a large table can take a very long time. Therefore, let’s look at a command that creates the table students with indexes already in place. CREATE TABLE students ( Id_studnet SMALLINT UNSIGNED NOT NULL AUTO_INCREMENT, name VARCHAR(10) NOT NULL, surname VARCHAR(20) NOT NULL, email VARCHAR(30) NOT NULL, INDEX(name(3)), INDEX(surname(5)), ,PRIMARY KEY(id_studnet),UNIQUE(email)); Another important index, PK, its single unique key for each student to enable instant accessing of a row. The importance of having a key with a unique value for each row will come up when we start to combine data from different tables. You can add PK, while you create the table at the first time, or later by issuing the following command: ALTER TABLE students ADD PRIMARY KEY(id_student); The last important index, FULLTEXT index Unlike a regular index, MySQL’s FULLTEXT allows super-fast searches of entire columns of text. It stores every word in every data string in a special index that you can search using “natural language,” in a similar manner to using a search engine. It’s not strictly true that MySQL stores all the words in a FULLTEXT index, because it has a built-in list of more than 500 words that it chooses to ignore because they are so common that they aren’t very helpful for searching anyway. This list, called stopwords, includes the, as, is, of, and so on. The list helps MySQL run much more quickly when performing a FULLTEXT search and keeps database sizes down. FULLTEXT indexes can be created for CHAR, VARCHAR, and TEXT columns only. A FULLTEXT index definition can be given in the CREATE TABLE statement when a table is created, or added later using ALTER TABLE (or CREATE INDEX). Adding a FULLTEXT index to the table students for the columns name and surname ALTER TABLE classics ADD FULLTEXT(name,surname); this index is in addition to the ones already created and does not affect them You can now perform FULLTEXT searches across this pair of columns. If you find that MySQL is running slower than you think it should be when accessing your database, the problem is usually related to your indexes. Either you don’t have an index where you need one, or the indexes are not optimally designed. Tweaking a table’s indexes will often solve such a problem. In the next tutorial, we will learn about, using FOREIGN KEY Constraints and how to join tables together.

This video explains analytical functions and how they are implemented in real projects. Analytical functions are somewhat similar to aggregate functions,but they offer much more. Why use analytical function ? They allow you to write fast and concise queries which otherwise will involve self join and long processing times They allow you to perform aggregate functions independently on sets of partitions. You can access values from previous rows in current row and you can restrict the window on which you want to apply this analytical function. I have given additional practice exercises along with the dataset so that you can comfortably work with analytical functions.

1Z0-052 How to create tablespace in Oracle database 11g
 
03:56
A tablespace is a logical storage unit in an Oracle database. It is called logical because a tablespace is not visible in the file system of the machine where the database resides. Each table, index, and file stored in an Oracle database belongs to the tablespace itself. A tablespace acts like a bridge between the Oracle database system and the filesystem in which the table's or index's data is stored. There are three types of tablespaces: Permanent tablespaces, Undo tablespaces and Temporary tablespaces.
