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.

SQL Server 4 - Beginner Terms Part 1
 
07:14
In order to be successful as a database developer, you need to speak the right language. I'm not talking about SQL or some programming language, I'm talking terminology. It is important to familiarize yourself with the most common terms as these terms allow us to communicate with other people in our field. Data - The role of a database is to store data. Data is the plural form of the word datum. If we had to define datum, we would say it is an individual fact or piece of information. This means that data is a collection of facts and information. Database - A collection of data. Database Management System (DBMS) - A software that it is capable of storing and interacting with that data. The software is also capable of presenting this data in some way that is user friendly. Even if our data is stored all over the computers secondary memory (SSD or HDD), the database will take the data and present it to us in an organized fashion, such as in a table. SQL Server is an example of a DBMS. In all reality, the distinction between a database and a DBMS is so small that most people use the terms interchangeably. Relational Database Management System (RDBMS) - A relational database is a type of DBMS. This means that all RDBMS are DBMSs, but not all DBMSs are RDBMSs. There are many other types of databases. A relational database presents our data in tables. Relation - This is a fancy pants word that means table. Table - A way to present data that has columns and rows. Columns say what data needs to be inserted and each row will insert data for every column. A database will often have numerous tables. A row can also be called a record. Where a specific column and row intersect is called a field, or a cell. Sometimes, we can fill out all of the information out for a row, but leave certain fields empty. If we do this, the field is said to be null. Null - The absence of a value. Database Design - Because our data is stored in tables, we have to go through an important process known as database design. In order for a database to work the way we intend for it to work, we have to design things. What data should we store, what tables do we create? What columns go in what tables? How are tables related? How do we ensure that our database is up to date? How do we protect our data? All of these questions bring up the concept of data integrity. This is the key term we will start with in the next video. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 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!)

2. Veri Tabanı Kavramları (SQL Server Management Studio Dersleri)
 
03:35
veri tabanı kavramını duymayanınız yoktur. neredeyse her alanda kullanılarak bilgi ihtiyacımızı karşılar. Veri tabanı kavramının açıklamasına geçmeden önce, söze, en temelden, Verinin tanımından başlayalım. Veri (datum) sayılar, rakamlar, sözcükler, metinler, resimler, olaylar vb. biçiminde temsil edilen ham gerçekliklerdir. Yani tek başlarına bir anlamları yoktur. Veriler bir arada belirli süreçlerden geçirildiklerinde, işlendiklerinde anlamlı hale gelerek Enformasyonu ve bilgiyi oluştururlar. Neyse konumuza dönelim. Veri farklı tür ve biçimdeki değerlerdir. Tablo ise verilerin bulunduğu hücrelerden oluşmaktadır. Bildiğiniz gibi iki boyutludur. Yani satır ve sütunlardan oluşmaktadır. Herhangi bir sütunda aynı tür verilerin saklıdır. Satırda ise herhangi bir varlığa veya nesneye ait ilişkili veriler bulunmaktadır. Mesela öğrenci tablosundaki bir kayıt herhangi bir öğrenciyle ilgili verileri barındırmaktadır. Satırlara aynı zamanda kayıt dendiğini de belirtmekte fayda var. Böylece aynı türden kayıtların bir araya gelmesi ile oluşan yapıya tablo denmektedir. Birbiri ile ilişkili tabloların ise bir araya gelmesi ile oluşan yapıya ise veri tabanı (database) denilmektedir Şimdi de veriler dosyalarda değil de neden tablolar halinde veri tabanlarında tutuluyor. Sorusunun cevabını birlikte arayalım. Veri tabanından önce programcılar verileri dosyaya kaydederken bazı sorunlar yaşadıkları biliniyor. Örneğin, Dosya kullanımında her bir uygulama için ayrıca tasarım yapılması gerekiyordu. Her uygulamada farklı dosya kullanımı veri tekrarına yol açtığı için bellek israfına ve veri bütünlüğünün sağlanamamasına sebep olunmaktaydı. Veri Bütünlüğünden kastım şu: düşünün ki aynı kayda ait verilerden bir kısmı farklı dosyalarda tutuluyor. Ve siz bu kaydı silmek isteseniz o kayıtla ilgili tüm dosyalardan verileri silmeniz gerekiyor. Diyelim ki bu aşamada bir hata oldu, bazı dosyalarda eksik ve kopuk veriler bulunacaktır. Diğer bir mesele, Veri Yapısına tam olarak sadece uygulamayı geliştiren programcı hakimdi. Programcı dolayısıyla verinin güvenliğinden de sorumluydu. Dosyalara Erişim Hızı yavaştı. Çok kullanıcı desteği bulunmuyordu. Arkadaşlar yeri gelmişken sıklıkla karıştırılan iki kavramı açıklamada yarar görüyorum. Veri tabanı ve veri tabanı yönetim sistemleri birbirinden farklıdır. Veri tabanı fiziksel olarak verilerin tutulduğu dosyalardır. Geleneksel dosya sistemlerinden farkını yukarıda açıklamaya çalıştık. Veri tabanı yönetim sistemi ise içinde çok sayıda veri tabanını, kullanıcıları, kullanıcı yetkileri ve diğer güvenlik araçlarını barındıran bir yazılımdır.
