MySQL 33 - Datetime, Date, Time Data Types
 
06:40
Next up on our MySQL to-do list is to learn about storing dates and times. There are various data types in MySQL for storing dates and times. It seems MySQL and databases likes to break everything up into multiple data types to make things more organized at the consequence of being confusing and annoying. This video is going to be talking about the DATETIME, DATE, and TIME data types. These are all used to store, you guessed it, dates and times. The one you choose depends on your needs. If you just need dates, choose DATE. If you just need times, choose TIME, if you need both stored together, choose DATETIME. Now you set a column one of these data types whenever you want every row for this field to have some sort of date, time or both…but how exactly is the data formatted? This requires us to understand some convention. For example, in the USA at least, if you have something like 4:30AM, by convention you know the hour is 4 and the minutes are 30. But this is just an agreed upon convention. MySQL has its own convention…For example 2017-02-02. The first thing is the year, the second is the month, and the third is the day. That is for the DATE. The convention for time is 22:54:30. The first is the hour (military time), the second is the minute, and the third is the seconds. Lastly, there can actually be fractions of seconds…up to microseconds! .123456. To use fractional seconds though you must specify to MySQL the precision of the TIME or DATETIME when you create it, for example DATETIME(6) would allow microsecond precision. How do you actually give a date to MySQL? By that I mean let's say you have a table with a column of DATETIME(6), and you want to give a value for that column, how do you format it? It's quoted. For example: '2017-02-02 22:54:30.333333' MySQL interprets this as a DATETIME. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 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!)

Analytical Functions in oracle explained with real examples
 
25:24
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. You can find the sample problems along with dataset in the below link. http://www.internshipsfromhome.com/oracle-analytical-functions-ddl-and-dml/

SQL Date Comparison - How to filter Datetime in SQL Server - SQL Training Online
 
08:41
http://www.sqltrainingonline.com SQL Date Comparison - How to filter Datetime in SQL Server - SQL Training Online In this video, I show you how to do a SQL Date Comparison in SQL Server when your Datetime has an actual time in it. I also include the latest trick that will make this easier if you are using SQL Server 2008 or SQL Server 2012. How do you compare a Datetime in SQL Server? A SQL Datetime stores both Date and Time. So when you are filtering using the SQL Where clause, you have to know if you Datetime is storing the time also. Let's take a look at the employee table in SQL Training Online Simple DB The column we are looking at is the hire date. I want to go after the person who was hired on February, 22 2005. So, I use the following SQL. select * from employee where hire_date='02/22/2005' Now, this works because we don't have any times stored in this column. But, if I change the record from 2005-02-22 00:00:00.000 to 2005-02-22 08:22:25.000 and rerun the query, you see that I don't get any results. That is because the value of 02/22/2005 is really 2005-02-22 00:00:00.000 and I just changed the hire_date to include a time other than 00:00:00.000. So, I have to tweak my query to use a greater than and less than sign. This works. But, to really understand what is going on, let me show you what SQL Server really sees. There are other ways, and in this StackOverflow article you can read more about these other ways. But, I want to point out a few. If you are working in SQL Server 2005 or earlier, the following is supposed to be the fastest performing way to do this. select datediff(dd,0, hire_date),* from employee where dateadd(dd,0, datediff(dd,0, hire_date)) = '2005-02-22' But, if you are working in SQL Server 2008 or SQL Server 2012, they have introduced an actual Date datatype that doesn't include the Time portion. Since this is the case, you can use the CAST function to remove the time from the Datetime. Here is the SQL to do that. select * from employee where CAST(hire_date AS Date) = '2005-02-22' And that's it. If you enjoy the video, please give it a like, comment, or subscribe to my channel.

Oracle DB Vs MySQL for Enterprise DataBase Deployments
 
08:54
Oracle DB is big, and expensive, but it brings a lot to the "table" when compared with MySQL. MySQL has limited ability to audit. MySQL's security is unsophisticated. There are no groups or roles, no ability to deny a privilege (you can only grant privileges). A user who logs in with the same username and password from different network addresses may be treated as a completely separate user. There is no built-in encryption comparable to Oracle. MySQL's Authentication is built-in. There is no LDAP, Active Directory, or other external authentication capability. MySQL has no MPP (massively parallel processing ) support. Unlike Oracle MySQL has no fractional-second storage type for times, dates, or intervals. There is no RAC (Real Application Cluster) support in My SQL, and no failover or server promotion either. These are strong features in Oracle MySQL's number of joins per query is limited to 61. Oracle's limit is much larger. MySQL Replication is asynchronous and has many limitations and edge cases. For example, it is single-threaded, so a powerful slave can find it hard to replicate fast enough to keep up with a less powerful master.

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.

Difference between rows and range
 
05:52
range vs rows in sql server difference between rows clause and range clause in sql server range clause vs rows clause in sql server sql server running total query running total example in sql server In this video we will discuss the difference between rows and range in SQL Server. This is continuation to Part 116. Please watch Part 116 from SQL Server tutorial before proceeding. Let us understand the difference with an example. We will use the following Employees table in this demo. SQL Script to create the Employees table Create Table Employees ( Id int primary key, Name nvarchar(50), Salary int ) Go Insert Into Employees Values (1, 'Mark', 1000) Insert Into Employees Values (2, 'John', 2000) Insert Into Employees Values (3, 'Pam', 3000) Insert Into Employees Values (4, 'Sara', 4000) Insert Into Employees Values (5, 'Todd', 5000) Go Calculate the running total of Salary and display it against every employee row The following query calculates the running total. We have not specified an explicit value for ROWS or RANGE clause. SELECT Name, Salary, SUM(Salary) OVER(ORDER BY Salary) AS RunningTotal FROM Employees So the above query is using the default value which is RANGE BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW This means the above query can be re-written using an explicit value for ROWS or RANGE clause as shown below. SELECT Name, Salary, SUM(Salary) OVER(ORDER BY Salary RANGE BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW) AS RunningTotal FROM Employees We can also achieve the same result, by replacing RANGE with ROWS SELECT Name, Salary, SUM(Salary) OVER(ORDER BY Salary ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW) AS RunningTotal FROM Employees What is the difference between ROWS and RANGE To understand the difference we need some duplicate values for the Salary column in the Employees table. Execute the following UPDATE script to introduce duplicate values in the Salary column Update Employees set Salary = 1000 where Id = 2 Update Employees set Salary = 3000 where Id = 4 Go Now execute the following query. Notice that we get the running total as expected. SELECT Name, Salary, SUM(Salary) OVER(ORDER BY Salary ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW) AS RunningTotal FROM Employees The following query uses RANGE instead of ROWS SELECT Name, Salary, SUM(Salary) OVER(ORDER BY Salary RANGE BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW) AS RunningTotal FROM Employees Notice we don't get the running total as expected. So, the main difference between ROWS and RANGE is in the way duplicate rows are treated. ROWS treat duplicates as distinct values, where as RANGE treats them as a single entity. All together side by side. The following query shows how running total changes 1. When no value is specified for ROWS or RANGE clause 2. When RANGE clause is used explicitly with it's default value 3. When ROWS clause is used instead of RANGE clause SELECT Name, Salary, SUM(Salary) OVER(ORDER BY Salary) AS [Default], SUM(Salary) OVER(ORDER BY Salary RANGE BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW) AS [Range], SUM(Salary) OVER(ORDER BY Salary ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW) AS [Rows] FROM Employees Text version of the video http://csharp-video-tutorials.blogspot.com/2015/10/difference-between-rows-and-range.html Slides http://csharp-video-tutorials.blogspot.com/2015/10/difference-between-rows-and-range_8.html All SQL Server Text Articles http://csharp-video-tutorials.blogspot.com/p/free-sql-server-video-tutorials-for.html All SQL Server Slides http://csharp-video-tutorials.blogspot.com/p/sql-server.html All Dot Net and SQL Server Tutorials in English https://www.youtube.com/user/kudvenkat/playlists?view=1&sort=dd All Dot Net and SQL Server Tutorials in Arabic https://www.youtube.com/c/KudvenkatArabic/playlists

Difference between DateTime and DateTime2 in SQL Server
 
10:42
datetime vs datetime2 sql server In this video we will discuss the difference between DateTime and DateTime2 in SQL Server The date range for DateTime is January 1, 1753, through December 31, 9999 where as for DateTime2 it is January 1, 0001, through December 31, 9999 The time range for DateTime is 00:00:00 through 23:59:59.997 where as for DateTime2 it is 00:00:00 through 23:59:59.9999999 Accuracy for DateTime is 3.33 Milli-seconds where as for DateTime2 it is 100 nanoseconds Storage size for DateTime is 8 Bytes where as for DateTime2 it is 6 to 8 Bytes (Depending on the precision required) The default value for both DateTime and DateTime2 is the same - 1900-01-01 00:00:00 DATETIME2 has a bigger date range than DATETIME. Also, DATETIME2 is more accurate than DATETIME. So I would recommend using DATETIME2 over DATETIME when possible. I think the only reason for using DATETIME over DATETIME2 is for backward compatibility. DateTime2 Syntax : DATETIME2 [ (fractional seconds precision) ] With DateTime2 Optional fractional seconds precision can be specified The precision scale is from 0 to 7 digits The default precision is 7 digits For precision 1 and 2, storage size is 6 bytes For precision 3 and 4, storage size is 7 bytes For precision 5, 6 and 7, storage size is 8 bytes Text version of the video http://csharp-video-tutorials.blogspot.com/2015/10/difference-between-datetime-and_21.html Slides http://csharp-video-tutorials.blogspot.com/2015/10/difference-between-datetime-and_20.html All SQL Server Text Articles http://csharp-video-tutorials.blogspot.com/p/free-sql-server-video-tutorials-for.html All SQL Server Slides http://csharp-video-tutorials.blogspot.com/p/sql-server.html All Dot Net and SQL Server Tutorials in English https://www.youtube.com/user/kudvenkat/playlists?view=1&sort=dd All Dot Net and SQL Server Tutorials in Arabic https://www.youtube.com/c/KudvenkatArabic/playlists

link of SQL substr blog : http://www.rebellionrider.com/SQL-substr-function.htm SQL substr function SQL Substr function will return a sub string of a specified length from the source string beginning at a given position. Tool used in this tutorial is command prompt. This tutorial series is part of SQL expert exam certification training. if you are preparing for SQL certification you can use my tutorials.

Let's see the Syntax Substr (source_string, start_pos, Substr_length) As we can see SQL substr function takes 3 parameters. First one is Source string from which you want to extract the segment. Second parameter is Starting position for sub string from the Source string. And the third parameter is Substr_length which is the length for the substring. First two parameters are mandatory to specify while third one is optional. So we can say. SQL Substr function will return a sub string of a specified length from the source string beginning at a given position. First parameter source string can be of any data type CHAR, VARCHAR2, NCHAR, NVARCHAR2, CLOB, or NCLOB whereas both start_pos, Substr_length parameters must be number data type. The returning result of SQL Substr function is of same data type of source string. Let's see an example of SQL Substr function. SELECT substr('www.RebellionRider.com',5,14) FROM dual; Here in this query url of my website www.RebellionRider.com is our source string with the total length of 22 characters, Now, I want to extract the name of my website that is, RebellionRider. So if you count the total length of the name of the website, it is 14. That's why I have specified 14 as my third parameter of SQL Substr function which is substr_length. Also the name of the website RebellionRider is starting from 5th position therefore I have specified 5 at second parameter of SQL substr function which is strt_pos or starting position. Execute it. Here is our result RebellionRider When starting position is larger than the length of source string. In this case SQL Substr function will return NULL as a result. Let's do an example. SELECT substr('www.RebellionRider.com',23,14) FROM dual; As you can see here I have specified 23 at starting position and the total length of our source string is 22 characters Let's execute And the result is Null. Second scenario When the Substr_length is greater than source string In this case the segment return is the substring from starting position to the end of the string. For example SELECT substr('www.RebellionRider.com',5,23) FROM dual; Our starting position is at 5 means at the first R of RebellionRider and length of substring is set to 23 which is greater than the length of source string that is 22. Execute. As you can see we get a substring from first R of RebellionRider till the end of the source String. Third scenario When you supply numeric or arithmetic expression or a DATE instead of character as Source string to SQL Substr function In this scenario If you have supplied a numeric string instead of character as source string, the oracle engine casts them as a character when they occur as parameter to SQL Substr function. And if you have supplied Arithmetic expression or a DATE then The Oracle engine first solves or evaluates the Arithmetic expression or the DATE Then casts them as a character. Means if you have arithmetic expression in your source string then oracle will first solve it and then change or say cast the value of its result into character. Let's see some example. SELECT substr(50000-7,2,4) FROM dual; Oracle first evaluates the arithmetic expression that is 50000-7 equals to 49993. And then oracle engine casts this result 49993 into a character string. Means 49993 will be a 5 characters string. Starting position of substring is 2, that means from the first 9 of 49993 We specified the length of substring is 4 so we must get 9993 as our result. Let's check execute

Sql date interview questions
 
10:59
In this video we will discuss the common date related sql interview questions and answers. If you are comfortable with the SQL Date functions, then you should be able to easily answer most of these questions. Text version of the video https://csharp-video-tutorials.blogspot.com/2018/11/sql-date-interview-questions.html Slides https://csharp-video-tutorials.blogspot.com/2018/11/sql-date-interview-questions-slides.html SQL Server Interview Questions and Answers https://www.youtube.com/playlist?list=PL6n9fhu94yhXcztdLO7i6mdyaegC8CJwR SQL Server Interview Questions and Answers - Text Articles & Slides http://csharp-video-tutorials.blogspot.com/2014/05/sql-server-interview-questions-and.html Angular, JavaScript, jQuery, Dot Net & SQL Playlists https://www.youtube.com/user/kudvenkat/playlists?view=1&sort=dd It is also useful to understand SQL CAST & CONVERT functions. We discussed DATE, CAST & CONVERT functions in Parts 25 to 28 in our SQL Server Tutorial. After watching this video you should be able to answer any sql date interview questions similar to the following. Write a SQL query to get 1. All people who are born on a given date (For example, 9th October 2017) 2. All people who are born between 2 given dates (For example, all people born between Nov 1, 2017 and Dec 31, 2017) 3. All people who are born on the same day and month excluding the year (For example, 9th October) 4. All people who are born yesterday, today, tomorrow, last seven days, and next 7 days 5. All people whose birth year is the same (For example, all people born in 2017, 2018 etc.) Once you are comfortable answering these questions you can extend the concepts you have learned to answer similar questions like the following. 1. Orders placed between 2 given dates or on a given day, month, year etc. 2. Customers gained or lost. 3. Employees joined or left etc.

Link for all dot net and sql server video tutorial playlists http://www.youtube.com/user/kudvenkat/playlists Link for slides, code samples and text version of the video http://csharp-video-tutorials.blogspot.com/2014/06/part-6-transform-rows-into-columns-in.html This is another common sql server interview question. We will be using Countries table in this example. SQL to create the table Create Table Countries ( Country nvarchar(50), City nvarchar(50) ) GO Insert into Countries values ('USA','New York') Insert into Countries values ('USA','Houston') Insert into Countries values ('USA','Dallas') Insert into Countries values ('India','Hyderabad') Insert into Countries values ('India','Bangalore') Insert into Countries values ('India','New Delhi') Insert into Countries values ('UK','London') Insert into Countries values ('UK','Birmingham') Insert into Countries values ('UK','Manchester') Here is the interview question. Write a sql query to transpose rows to columns. Using PIVOT operator we can very easily transform rows to columns. Select Country, City1, City2, City3 From ( Select Country, City, 'City'+ cast(row_number() over(partition by Country order by Country) as varchar(10)) ColumnSequence from Countries ) Temp pivot ( max(City) for ColumnSequence in (City1, City2, City3) ) Piv
