Learn more on www.pravendragaur.com Constraints are the rules which applied on data columns on table. These are used to limit the type of data that can go into a table. This ensures the accuracy and reliability of the data in the database. Constraints could be column level or table level. Column level constraints are applied only to one column, whereas table level constraints are applied to the whole table. Types of Constraints 1. Unique 2. Not null 3. Primary Key 4. Check 5. Foreign Key

SQL Tutorial - CHECK Constraints
 
13:05
Another fantastic SQL Tutorial brought you by BeardedDev. Tutorials on SQL Querying, SQL Development, Database Administration, Data Analysis and Business Intelligence. Subscribe to the channel for more fantastic tutorials. This video contains everything you need to know about CHECK Constraints in SQL Server with working examples. CHECK Constraints allow us to enforce limits on the data that can be entered in to our tables, in this tutorial we look at preventing entering Sales Values that are less than or equal to 0, after all we don't sell anything for nothing. CHECK Constraints only prevent values that evaluate to false from being added and we work through another example of how CHECK Constraints do not prevent NULLs from being added if the Data Definition allows. All Constraints are associated with Tables so if a Table is removed the Constraint is removed too. There is another example of how we can only add CHECK Constraints to existing columns if the data within that column meets the requirements of the Constraint. We also discuss how we can query the System Table, sys.check_constraints to retrieve information about CHECK Constraints within the Database. CHECK Constraint Syntax: CREATE TABLE dbo.Sales ( Sales_Id INT IDENTITY(1, 1) , Sales_Date DATE , Sales_Value DECIMAL(16, 2) [constraint name] CHECK (Sales_Value [greater than] 0) ) ALTER TABLE [table name] ADD CONSTRAINT [constraint name] CHECK (column [less than or greater than or equal to] value) Associated Videos: Create Table with Constraints - https://youtu.be/bfBnZKf2EGg Recently Uploaded Videos: SSIS Tutorial - How to Create Connection Managers - https://youtu.be/5SNHNlBmbi8 Different Roles working with Data - https://youtu.be/lBU1XQ87cLg SQL Tutorial - Window Functions - https://youtu.be/H6OTMoXjNiM

NULL value is different than a zero value or a field that contains spaces By default, a column can hold NULL values. The NOT NULL constraint enforces a column to NOT accept NULL values. This enforces a field to always contain a value, which means that you cannot insert a new record, or update a record without adding a value to this field

SQL Server 26 - PRIMARY KEY, NOT NULL, UNIQUE
 
03:36
In the last video we created our first table, but I want to give SQL Server some extra information so the database knows more about each of the columns. The first thing is to establish the primary key. To do this all we do is add PRIMARY KEY after the column we want to be the primary key. Simple enough. When we add a constraint right after the column like this, it is often called a column attribute. CREATE TABLE Animals( ID INT PRIMARY KEY, Name VARCHAR(50), Species VARCHAR(50) ); Additionally, if you are using an ID column, it is best to have it labeled as the IDENTITY column. That way, SQL Server will automatically increment the number. CREATE TABLE Animals( ID INT PRIMARY KEY IDENTITY, Name VARCHAR(50), Species VARCHAR(50) ); The other attributes we've discussed in this series are NOT NULL and UNIQUE. We can make the name NOT NULL and the species NOT NULL. We don't have a good column for UNIQUE, so let's add one: CREATE TABLE Animals( ID INT PRIMARY KEY IDENTITY, Name VARCHAR(50) NOT NULL, Species VARCHAR(50) NOT NULL, ContactEmail VARCHAR(50) NOT NULL UNIUQE ); You can see that it is very easy to add multiple column attributes to a column. Just separate them by spaces. The order does not matter. Also, when you say primary key the column is automatically NOT NULL and UNIQUE. There are other attributes you can use including DEFAULT, FOREIGN KEY, and SPARSE. DEFAULT will give a value for a column if you do not put anything in yourself. Foreign keys are used to reference other columns. SPARSE is an attribute we haven't discussed. You can use SPARSE if most of the rows are going to have a NULL for a column and it saves storage space, but we will worry about that in another 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!)

SQL Server 29 - How to Name Constraints
 
03:42
Our database has some primary and foreign keys, but occasionally people want to name them. That way, we can refer to a constraint specifically by a user friendly name. The trick is to simply add CONSTRAINT xx_ConstraintName before the constraint. Typically, the constraint name will follow the pattern of 2 letters to represent what type of constraint, followed by an Underscore, followed by the name. Here is an example: CREATE TABLE Interests( AnimalID INT NOT NULL, SpeciesID INT NOT NULL, CONSTRAINT PK_Interests PRIMARY KEY (AnimalID, SpeciesID) ); Now what do you name the constraint? Ultimately, that is a decision that is up to you. There are some conventions. The convention I used in this example is known as Hungarian notation. Hungarian notation is when we include what the thing is inside of the name. By prefixing the name with PK_ we automatically know that this is a primary key constraint. Some people prefer to put the PK at the end, and some people don't like to put it in there at all. Then, after the PK_, I put the name of the table to say that it is the primary key for that table. We can do the same with the foreign keys: CREATE TABLE Interests( AnimalID INT NOT NULL, SpeciesID INT NOT NULL, CONSTRAINT FK_InterestsAnimals FOREIGN KEY (AnimalID) REFERENCES Animals(ID), CONSTRAINT FK_InterestsSpecies FOREIGN KEY (AnimalID) REFERENCES Animals(ID), CONSTRAINT PK_Interests PRIMARY KEY (AnimalID, SpeciesID) ); The naming convention for the foreign keys is FK_ followed by the table name, followed by the Table it references. This is an okay naming convention. It can get confusing if you, for example had two columns from the Interests table referencing the Animals table. Much better. Why is it so important to name constraints? One of the primary reasons is so if SQL Server ever complains about a constraint violation, you will know exactly what constraint it is talking about without having to go search for it: INSERT INTO Interests VALUES (1, 3); SQL Server responds with: "The INSERT statement conflicted with the FOREIGN KEY constraint "FK_InterestsAnimals". This is an example of an INSERT statement. We will introduce this in more detail 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!)

SQL Tutorial - Create Table with Constraints
 
20:35
This video tutorial will show you how to create a table with constraints in Microsoft SQL Server. The video covers, data types of columns, NOT NULL constraints, PRIMARY KEY constraints, FOREIGN KEY constraints, CHECK constraints and DEFAULT constraints. Data types enforce limits to the what can inserted in to tables and constraints further build on this, for example if you wanted to add a column called age, the values will usually range from 0 - 100 so we could choose a data type of TINYINT which allows values of up to 255 but this means if you enter 255 this is still a valid age. We want to control this even further so we can add a CHECK constraint that will only allow values from 0 - 100. Check out the video for how to add this constraint. CREATE TABLE dbo.[Login] ( Username VARCHAR(30) NOT NULL CONSTRAINT PK_Login_Username PRIMARY KEY (Username) , [Password] VARCHAR(30) NOT NULL , LastUpdate DATETIME2 NOT NULL CONSTRAINT DF_Login_LastUpdate DEFAULT (CURRENT_TIMESTAMP) , [Status] CHAR(10) NOT NULL CONSTRAINT CK_Login_Status CHECK ([Status] IN ('Active', 'Inactive')) , CustomerID INT CONSTRAINT FK_Login_CustomerId FOREIGN KEY (CustomerId) REFERENCES Customers (CustomerId) )
