Oracle LEAST Function
 
02:46
https://www.databasestar.com/oracle-greatest/ The Oracle LEAST function is a useful function, but I don’t think it’s very well understood. It returns the least or smallest value in a set of values. You can provide the values, and use numbers or text values. The syntax for the Oracle LEAST function is: LEAST(expr1 [, expr_n]) The expr1 is the first expression to use for your comparison. Expr_n is one or more expressions to use in the comparison, separated by commas. This is optional. So how is LEAST calculated? If the parameters are numeric, the LEAST function finds the smallest number. If the parameters are characters, the function finds the earliest value if they were sorted alphabetically (using their character values). What data type is returned? It depends on the parameters you provide. It could be the same as the parameters you provide, or VARCHAR2 if the parameters are all characters. You can also use the LEAST function with dates. It’s the opposite of the GREATEST function. For more information on the LEAST function, including the SQL used in this video and the examples, read the related post here: https://www.databasestar.com/oracle-greatest/

There are several ways of finding the nth highest salary. By the end of this video, we will be able to answer all the following questions as well. How to find nth highest salary in SQL Server using a Sub-Query How to find nth highest salary in SQL Server using a CTE How to find the 2nd, 3rd or 15th highest salary Let's use the following Employees table for this demo Use the following script to create Employees table Create table Employees ( ID int primary key identity, FirstName nvarchar(50), LastName nvarchar(50), Gender nvarchar(50), Salary int ) GO Insert into Employees values ('Ben', 'Hoskins', 'Male', 70000) Insert into Employees values ('Mark', 'Hastings', 'Male', 60000) Insert into Employees values ('Steve', 'Pound', 'Male', 45000) Insert into Employees values ('Ben', 'Hoskins', 'Male', 70000) Insert into Employees values ('Philip', 'Hastings', 'Male', 45000) Insert into Employees values ('Mary', 'Lambeth', 'Female', 30000) Insert into Employees values ('Valarie', 'Vikings', 'Female', 35000) Insert into Employees values ('John', 'Stanmore', 'Male', 80000) GO To find the highest salary it is straight forward. We can simply use the Max() function as shown below. Select Max(Salary) from Employees To get the second highest salary use a sub query along with Max() function as shown below. Select Max(Salary) from Employees where Salary [ (Select Max(Salary) from Employees) To find nth highest salary using Sub-Query SELECT TOP 1 SALARY FROM ( SELECT DISTINCT TOP N SALARY FROM EMPLOYEES ORDER BY SALARY DESC ) RESULT ORDER BY SALARY To find nth highest salary using CTE WITH RESULT AS ( SELECT SALARY, DENSE_RANK() OVER (ORDER BY SALARY DESC) AS DENSERANK FROM EMPLOYEES ) SELECT TOP 1 SALARY FROM RESULT WHERE DENSERANK = N To find 2nd highest salary we can use any of the above queries. Simple replace N with 2. Similarly, to find 3rd highest salary, simple replace N with 3. Please Note: On many of the websites, you may have seen that, the following query can be used to get the nth highest salary. The below query will only work if there are no duplicates. WITH RESULT AS ( SELECT SALARY, ROW_NUMBER() OVER (ORDER BY SALARY DESC) AS ROWNUMBER FROM EMPLOYEES ) SELECT SALARY FROM RESULT WHERE ROWNUMBER = 3

Should I Learn Oracle or SQL Server?
 
02:17
Should I learn Oracle or SQL Server? While Oracle DBA certification pays well, the classes and getting a practice version of Oracle is expensive. I heard you could get versions of SQL Server for free. Part of it depends on the software developers you're working with. Use SQL Server if you're working with Microsoft's .Net, whereas Java developers are more likely to use Oracle. I didn't know that SQL Server was a Microsoft brand. So if you'll be working on MS servers and MS databases, you need to learn the SQL server. Which one is better for my career? There are typically more MS SQL jobs, but the Oracle jobs pay more. Oracle doesn't have as many jobs, but you have less competition. Those who didn't join the Microsoft cult pay a price for it. Which one is harder to learn? Oracle is rather complex, whereas MS SQL Server is simpler because it has a good graphical user interface. It's nice to hear that Microsoft made at least one good user interface. They usually put out crap, but once in a while, there's a good one. I've heard MySQL is more popular. Only because of the so called popularity of Microsoft. Oracle is the heavyweight database tool. Which relational database is better? MySQL works with almost any web-based application. Oracle is more stable, secure and scalable for enterprise wide applications. I'm glad to know that the big data that is running the world isn't all beholden to Bill Gates. No, but most PCs that generate the data still are. It sounds like I need to learn Oracle. Fortunately, you can learn Oracle inside and out and a little MS SQL and do almost any database admin job you'd like. You're guaranteed to get dates if you can proudly announce you have stable, well paying employment. It's like saying you're a musician, artist and athlete at once. Girls will just be happy if she doesn't have to pay for the date these days.

Oracle Database Tutorial 7: The "Like" Operator In Sql
 
04:29
The LIKE operator is used in a WHERE clause to search for a specified pattern in a column. There are two wildcards used in conjunction with the LIKE operator: % - The percent sign represents zero, one, or multiple characters _ - The underscore represents a single character Note: MS Access uses a question mark (?) instead of the underscore (_). The percent sign and the underscore can also be used in combinations! LIKE Syntax SELECT column1, column2, ... FROM table_name WHERE columnN LIKE pattern; Tip: You can also combine any number of conditions using AND or OR operators. Here are some examples showing different LIKE operators with '%' and '_' wildcards: LIKE Operator Description WHERE CustomerName LIKE 'a%' Finds any values that starts with "a" WHERE CustomerName LIKE '%a' Finds any values that ends with "a" WHERE CustomerName LIKE '%or%' Finds any values that have "or" in any position WHERE CustomerName LIKE '_r%' Finds any values that have "r" in the second position WHERE CustomerName LIKE 'a_%_%' Finds any values that starts with "a" and are at least 3 characters in length WHERE ContactName LIKE 'a%o' Finds any values that starts with "a" and ends with "o" sql like wildcard sql like multiple values sql like pattern like query in mysql sql like regex sql not like in operator in sql sql like escape 1 2 3 4 5 6 7 8 9 10 Next

Learn how to use SQL for Pattern Matching. Row pattern matching in native SQL improve application and development productivity and query efficiency for row-sequence analysis. Recognizing patterns in a sequence of rows has been a capability that was widely desired, but not possible with SQL until now. With Oracle Database 12c Release 1 (12.1), you can use the MATCH_RECOGNIZE clause to perform pattern matching in SQL.

What is Autonomous transaction in Oracle
 
05:05
What is Autonomous transaction in Oracle. This is very frequently asking question in Interview. Hello Friend, in this Video You can learn how we can give the answer of Autonomous Transactions. An autonomous transaction is available from Oracle 8i. It is a very cool, useful, unique and powerful feature in oracle. An autonomous transaction is an independent transaction that is initiated by another transaction. It must contain at least one Structured Query Language (SQL) statement. When an autonomous transaction is called, the original transaction (calling transaction) is temporarily suspended. The autonomous transaction must commit or roll back before it returns control to the calling transaction. Once changes have been made by an autonomous transaction, those changes are visible to other transactions in the database. Autonomous transactions can be nested. For use Autonomous Transactions feature in program we have to use PRAGMA AUTONOMOUS_TRANSACTION Key word in Program When to use Autonomous Transactions? • Logging mechanism you need to log an error to your database log table. On the other hand, you need to roll back your core transaction because of the error. And you don't want to roll back over other log entries. • Commits and rollbacks in your database triggers If you define a trigger as an autonomous transaction, then you can commit and/or roll back in that code. • Software usage meter You want to keep track of how often a program is called during an application session. This information is not dependent on, and cannot affect, the transaction being processed in the application. Mutation Error Using autonomous transaction we can avoid mutation error.

COALESCE IN ORACLE SQL
 
06:50
This video is the 4th video in the series of 'working with null', this video explains the working of the coalesce function in oracle sql. Also the video explains the use of coalesce function in oracle sql queries by perfect simple and easy to understand examples. COALESCE returns the first non-null expr in the expression list. You must specify at least two expressions. If all occurrences of expr evaluate to null, then the function returns null. Oracle Database uses short-circuit evaluation. The database evaluates each expr value and determines whether it is NULL, rather than evaluating all of the expr values before determining whether any of them is NULL. If all occurrences of expr are numeric datatype or any non numeric datatype that can be implicitly converted to a numeric datatype, then Oracle Database determines the argument with the highest numeric precedence, implicitly converts the remaining arguments to that datatype, and returns that datatype.

Oracle SQL Tutorial 30 - UTF-8 and UTF-16 Character Sets
 
04:01
A few videos ago we discussed UTF-8 and UTF-16 encoding, but when we are working with a database we do not worry about encodings as much as we do character sets. That's because a specific character set is going to have a specific encoding. The reason I am making this video is to introduce you to the most common character sets and to teach you the differences. That’s because as we go into the national character sets we need to understand the information taught in this video. So the first character set I am going to teach you about is AL32UTF8. AL32UTF8 is a character set that uses the uff-8 encoding and each character can take up to 4 bytes with the utf-8 encoding. There is another character set (not encoding) called utf8 (no hyphen) which is also encoded with UTF-8. This can be a little confusing because UTF8 is the name of an encoding and a character set, but bear with me. Both of these character sets are UTF-8 encoded, but UTF8 uses an older version of UTF-8 encoding. Generally, they work about the same, but the way certain characters are stored is slightly different, specifically way certain characters are stored is slightly different, specifically what are known as supplementary characters, which take up 4 bytes. The max size for a UTF8 character set is 3 bytes, as they do not directly support the supplementary characters as 4 bytes but instead store them across 2 groups of 3 bytes each. Oracle recommends that you use AL32UTF8 for all future development instead of the archaic UTF8 character set. There is another character set that you should know about, and that is AL16UTF16, which uses the UTF-16 encoding. Watch my video over UTF-8 and UTF-16 to learn more about UTF-16. Lastly, there is a character set known as UTFE, which uses an encoding known as UTF-EBCDIC. This is like a super archaic character set, and I'm not even going to talk about it. I thought I would at least mention it as it is going to come up a bit in the next video's topic. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 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!)

Oracle SQL Tutorial 28 - CHAR Part 2
 
03:33
Now this video is a continuation of the last video. I decided to break the video up into sections so they didn't cover so much information and drag on for 10 minutes. This video we are going to talk about the length of CHAR. Now it is important to remember that CHAR is a fixed-length data type. This means that every row's value for this column is going to have the same length. The length is given to the database by specifying the length in parenthesis, such as CHAR(10). If you give a value shorter than that, it will be padded with spaces. What range is allowed though? The lowest is actually one. The highest is 2000. Now, remember that Oracle allows either the specification of CHAR or BYTE. The limit of 2000 is actually 2000 bytes. What happens if you put 2000 CHAR? Well, Oracle actually lets you do that. What is the problem with this though? The problem is that not all characters are 1 byte. This means that our 2000 CHAR is inaccurate. This will only work with 1 byte characters. This might not seem like a big problem, but it can lead to runtime errors in code that uses our database. A runtime error is when our code runs and in certain circumstances we get an error and others we do not. If we allow a user to insert up to 2000 characters, but they decide to use multibyte characters such as Chinese, we will get an error. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 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!)

Full Transportable Export/Import into the DBaaS Cloud - Oracle 12c
 
20:54
Video provided by Roy Swonger - Database Upgrade and Utilities Product Manager and Senior Director at Oracle Corporation Video lenght: 20 minutes This video demonstrates first of all how to use the Oracle Database 12c feature "Full Transportable Export/Import". This feature utilized Transportable Tablespaces as a cross-version and cross-platform migration technology but let Oracle Data Pump handle all the manual stuff involved with TTS and xTTS in just one command. Furthermore the feature can be combined with RMAN Incremental Backups to decrease the downtime if necessary and desired. Please find a presentation at the Database Upgrade Blog at: https://blogs.oracle.com/UPGRADE/ in the Slides Download Center titled: Full Transportable Export/Import with RMAN Incrementals In addition Roy is demonstrating also how to utilize this feature to migrate a database into the Oracle DBaaS Cloud. Interesting fact: Even though Full Transportable Export is an Oracle Database 12c feature included in the standard license set it can be used with an Oracle 11.2.0.3 or Oracle 11.2.0.4 database - but the destination version must be at least an Oracle Database 12.1.0.1 (or newer). Further question? Please get in touch with us via the Oracle Database Upgrade Blog: https://blogs.oracle.com/UPGRADE/ Thanks!
