Oracle SQL Tutorial 12 - Intro to Constraints
 
06:13
As I believe I've mentioned in an earlier video, a constraint is basically a rule we can put in our database that prevents someone from putting the wrong data in. It protects our relationships and data integrity. Because the goal of these constraints are to protect our data integrity, you may hear them called integrity constraints. There are many integrity constraints we are going to talk about: NOT NULL UNIQUE PRIMARY KEY FOREIGN KRY CHECK There is also the DEFAULT attribute. These are all keywords we can add to our columns that will change the way the database works with our data and also prevents incorrect data. NOT NULL is a constraint you can put on a column that prevents nulls. A null is the absence of a value. When we say null, we are saying that every single row has to have a value for this column. UNIQUE is a constraint that makes every row have a unique value for this column. Now note, this does not require values to be put it, and it will allow multiple rows to be null. Next, we are going to talk about primary keys. What qualifies a column as a candidate key? First, not a single row should have a null for that column. Second, every row must be unique. The primary key constraint is essentially a combination of the NOT NULL constraint and the UNIQUE constraint. The foreign key constraint sets the requirement that any value in this column for any row must match a row in another column. Check constraints allow us to be more strict with what data is allowed in our database. NOT NULL and UNIQUE give some level of restriction, but what if we want something more specific? For example, what if we only want values between 0 and 100? That is where check constraints come in. When using check constraints, you give a boolean expression. A boolean expression is something that can be evaluated to true or false. It will only insert the row if the value you try to put into the row makes the expression evaluate to true. So if you put in a value too great or small, the expression will be false and the data is not allowed to be entered. The default constraint is a value you can give a column, and if for any reason when the row is created in the table a value is not provided, the default value will be given. So for example, we could have a bank account table where the balance defaults to 0. How do you actually implement these constraints when you are creating a table? In the next video we are going to be adding these to our users table.

Oracle SQL Tutorial 23 - Intro to Data Types
 
05:03
Every column within a table has to be given what is known as a datatype. A data type is a fairly simple concept when you dissect the word. It is literally the type of data. Why do we use types, though? The biggest benefit is so that Oracle knows how to interpret and work with our data. It also makes the database better at rejecting incorrect data. If we had to concept of a data type, there would be a lot more work involved in forcing data to be of the right format. It would also be harder for us to get the database to treat the data in the correct way. In addition to this, a database can optimize storage and performance for a column if everything is of the same data type. Because of this, each column can only support one data type. There are numerous different data types in Oracle and it helps us if we categorize them. The first types of datatypes we should learn about are: String, Numeric, Temporal Now, there are few more categories we could make, but these are the main ones. We will worry about the other ones another day as I am only introducing the topic. A string data type is anything within quotes. Most databases use single quotes for string data. Inside of the quotes can be any number of characters. What is a character? Think of any letter, number, or symbol you can type. Some people call these letters, numbers, and symbols alphanumeric. Numeric data type includes only numbers. These data types are often used for data that you plan on using for mathematical calculations. Temporal data types are data types that are used for dates and times. Now, each data type is probably going to have some options you'll need to worry about, but one that comes up with every data type is storage. The reason we need to consider storage is because we may end up with millions of rows in a table and the difference between a few bytes for each row will make a huge difference when we look at the whole picture. When a data type gives you the option of size, you will want to a size that will be able to hold what you need, but nothing more. In the upcoming videos we are going to discuss the available data types in more detail. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 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: Check Constraint
 
05:11
In this tutorial, you'll learn how to make use of check constraint. PL/SQL (Procedural Language/Structured Query Language) is Oracle Corporation's procedural extension for SQL and the Oracle relational database. PL/SQL is available in Oracle Database (since version 7), TimesTen in-memory database (since version 11.2.1), and IBM DB2 (since version 9.7).[1] Oracle Corporation usually extends PL/SQL functionality with each successive release of the Oracle Database. PL/SQL includes procedural language elements such as conditions and loops. It allows declaration of constants and variables, procedures and functions, types and variables of those types, and triggers. It can handle exceptions (runtime errors). Arrays are supported involving the use of PL/SQL collections. Implementations from version 8 of Oracle Database onwards have included features associated with object-orientation. One can create PL/SQL units such as procedures, functions, packages, types, and triggers, which are stored in the database for reuse by applications that use any of the Oracle Database programmatic interfaces. PL/SQL works analogously to the embedded procedural languages associated with other relational databases. For example, Sybase ASE and Microsoft SQL Server have Transact-SQL, PostgreSQL has PL/pgSQL (which emulates PL/SQL to an extent), and IBM DB2 includes SQL Procedural Language,[2] which conforms to the ISO SQL’s SQL/PSM standard. The designers of PL/SQL modeled its syntax on that of Ada. Both Ada and PL/SQL have Pascal as a common ancestor, and so PL/SQL also resembles Pascal in several aspects. However, the structure of a PL/SQL package does not resemble the basic Object Pascal program structure as implemented by a Borland Delphi or Free Pascal unit. Programmers can define public and private global data-types, constants and static variables in a PL/SQL package.[3] PL/SQL also allows for the definition of classes and instantiating these as objects in PL/SQL code. This resembles usage in object-oriented programming languages like Object Pascal, C++ and Java. PL/SQL refers to a class as an "Abstract Data Type" (ADT) or "User Defined Type" (UDT), and defines it as an Oracle SQL data-type as opposed to a PL/SQL user-defined type, allowing its use in both the Oracle SQL Engine and the Oracle PL/SQL engine. The constructor and methods of an Abstract Data Type are written in PL/SQL. The resulting Abstract Data Type can operate as an object class in PL/SQL. Such objects can also persist as column values in Oracle database tables. PL/SQL is fundamentally distinct from Transact-SQL, despite superficial similarities. Porting code from one to the other usually involves non-trivial work, not only due to the differences in the feature sets of the two languages,[4] but also due to the very significant differences in the way Oracle and SQL Server deal with concurrency and locking. There are software tools available that claim to facilitate porting including Oracle Translation Scratch Editor,[5] CEITON MSSQL/Oracle Compiler [6] and SwisSQL.[7] The StepSqlite product is a PL/SQL compiler for the popular small database SQLite. PL/SQL Program Unit A PL/SQL program unit is one of the following: PL/SQL anonymous block, procedure, function, package specification, package body, trigger, type specification, type body, library. Program units are the PL/SQL source code that is compiled, developed and ultimately executed on the database. The basic unit of a PL/SQL source program is the block, which groups together related declarations and statements. A PL/SQL block is defined by the keywords DECLARE, BEGIN, EXCEPTION, and END. These keywords divide the block into a declarative part, an executable part, and an exception-handling part. The declaration section is optional and may be used to define and initialize constants and variables. If a variable is not initialized then it defaults to NULL value. The optional exception-handling part is used to handle run time errors. Only the executable part is required. A block can have a label. Package Packages are groups of conceptually linked functions, procedures, variables, PL/SQL table and record TYPE statements, constants, cursors etc. The use of packages promotes re-use of code. Packages are composed of the package specification and an optional package body. The specification is the interface to the application; it declares the types, variables, constants, exceptions, cursors, and subprograms available. The body fully defines cursors and subprograms, and so implements the specification. Two advantages of packages are: Modular approach, encapsulation/hiding of business logic, security, performance improvement, re-usability. They support object-oriented programming features like function overloading and encapsulation. Using package variables one can declare session level (scoped) variables, since variables declared in the package specification have a session scope.

IIF function Introduced in SQL Server 2012 Returns one of two the values, depending on whether the Boolean expression evaluates to true or false IIF is a shorthand way for writing a CASE expression Syntax : IIF ( boolean_expression, true_value, false_value ) Example : Returns Male as the boolean expression evaluates to TRUE DECLARE @Gender INT SET @Gender = 1 SELECT IIF( @Gender = 1, 'Male', 'Femlae') AS Gender Example : Using IIF() function with table data. We will use the following Employees table for this example. SQL Script to create Employees table Create table Employees ( Id int primary key identity, Name nvarchar(10), GenderId int ) Go Insert into Employees values ('Mark', 1) Insert into Employees values ('John', 1) Insert into Employees values ('Amy', 2) Insert into Employees values ('Ben', 1) Insert into Employees values ('Sara', 2) Insert into Employees values ('David', 1) Go Write a query to display Gender along with employee Name and GenderId. We can achieve this either by using CASE or IIF. Using CASE statement SELECT Name, GenderId, CASE WHEN GenderId = 1 THEN 'Male' ELSE 'Female' END AS Gender FROM Employees Using IIF function SELECT Name, GenderId, IIF(GenderId = 1, 'Male', 'Female') AS Gender FROM Employees Text version of the video http://csharp-video-tutorials.blogspot.com/2015/10/iif-function-in-sql-server.html Slides http://csharp-video-tutorials.blogspot.com/2015/10/iif-function-in-sql-server_14.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

MySQL 25 - CHAR Data Type
 
04:47
The first category of data types that we are going to cover in this MySQL series are the string data types, or character data types. There are two that I am going to talk about in this video, CHAR and VARCHAR. We'll start with CHAR. CHAR is a string data type where you specify how many characters are allowed in parenthesis after you declare the column as this type. For example, we can say CHAR(50) to allow up to 50 characters for each value in that column. The thing to know about CHAR though is that it is a fixed-length string. That means every single value inside of that column is actually going to be whatever you declare the length as. So if you say CHAR(50), every string is going to be 50 characters long. If, for example, you have a row that only uses 40 characters, MySQL will pad the right side of the string with spaces until it fills 50 characters. Now, the highest value you can put in here is 255. The 255 refers to characters. This means that you can have strings with up to 255 characters. How does the computer know how to store these characters? That has to deal with the character set and the encoding of the characters. By default, MySQL is going to use UTF-8. We are not going to discuss UTF-8 in detail for a while but essentially UTF-8 says that each character can take up to 3 bytes of storage. 255 comes from the max number you can count to using binary. So if we are keeping track of how many values are in this column in an 8 bit number, 255 is the highest. If you don't know what I'm talking about it, we'll worry about it later. You can actually make the column CHAR(0). In this situation, the only thing you could put in as a value for this column is an empty string (''). When retrieving variable length CHAR data from a database it may not look like the database pads the value. That's because MySQL actually strips spaces from the value when presented. If you want to keep all of the spaces that have been added when you retrieve the value, you can do that. Look up PAD_CHAR_TO_FULL_LENGTH online. In the next video we are going to discuss VARCHAR. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 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!)

MySQL 24 - Important Data Types
 
05:33
I decided that instead of going through all of the categories of data types real slow, I'm going to give you a video that gives you the most important data types. That way, you can have a pretty good idea of what data types you need to use and when. Also, if any of the info in this video is too fast, you can watch the next videos to get a more in depth understanding. The first data type is CHAR. This data type stores a string that is of a fixed length. You will only want to use this when you know the length of the data for the column. For example, you might have a column for phone numbers. As long as you know that every phone number is going to be the same format, you could use a column with the CHAR data type. You would just specify it as CHAR(length). VARCHAR works in a similar fashion to CHAR, but it works best for variable length data. That means that if you have a column where each row is going to have a different length, you would want to use VARCHAR. For example, if you had a column for an email address, each email is going to be any number of characters. Now, we are going to be going into numeric data types. For each of the numeric data types there are two variations. Signed and unsigned. Signed data types allow for negative values, but the highest value will be lower. Unsigned do not allow negatives but can store higher positive numbers. INT is the data type you use when you need whole numbers. This is likely going to be the data type used for ID columns. DOUBLE is the data type that can be used when you need to store a real number. This means that there can be numbers after a decimal point. There is also a data type called FLOAT. This works similarly but cannot handle as many numbers after the decimal. These data types have the downside in that they often cannot be trusted when doing math. Only use DOUBLES for data where it is acceptable to be pretty close to correct. DECIMAL is a datatype that can be used for numbers where precision is extremely important. For example, Decimal can be used for columns dealing with money, important measurements, or anything where we need the data to work 100% as expected in arithmetic. TIMESTAMP is a column that is used to easily record an instance in time. This is often used to record when row is created or updated. That's because it will automatically generate a value when an INSERT or UPDATE is issued against the database. DATE, DATETIME, and TIME are all used to store dates and times. There are some differences between these and a TIMESTAMP, but I'll just give you one for now to tease you To understand the differences between these and the timestamp, you need to understand something known as UTC time. UTC time is a standard that you can compare against all time zones. It is known as coordinated universal time. So for example, PST is 8 hours behind UTC. The different between TIMESTAMP and these is that TIMESTAMP will convert whatever value to UTC when stored, and convert it back to whatever your time zone is when you retrieve it. This means that if you want to store a date that is going to change to the users time zone when retrieved, use TIMESTAMP. If it needs to stay the same no matter what, use DATETIME. If that's not super clear, we'll try to discuss it in more detail in an upcoming video. The goal of this video was not to teach you the intimate details on defining data types. The goal was to give you a rough over view of the main data types you will find in MySQL. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 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!)

ADF Training | Performing Multiple Row Selection with Oracle ADF Tables
 
12:47
This video tutorial from https://www.fireboxtraining.com/oracle-adf-training demonstrates how to handle multiple selection on Oracle ADF Faces tables. We are working with an existing custom Oracle ADF view object custom method that takes a List of Key objects. In our JSF page, we create a managed bean method that returns the keys of the table records that the user selected. We then use bindings to reference the data on the model layer.

79. Show/hide dialog fields with a Checkbox in AEM.
 
05:34
Show/Hide(toggle) dialog fields with a Checkbox in AEM: There may be a requirement when you want to change the dialog fields based on the selection of the Checkbox like I shown in this video clip. Out of the box AEM doesn't provide this functionality using checkbox. I have the Javascript js that we can use to achieve this. Use the link https://github.com/pankajchhatri/AEM to copy the JS file. To use this custom js, create the client library with category cq.authoring.dialog. There are 3 steps to use checkbox show/hide. 1. Add cq-dialog-dropdown-showhide class to checkbox field. 2. Add cq-dialog-dropdown-showhide-target data attribute to the dropdown and value will be jquery selector I have used .togglefields. 3. Add the selector class to each field that you want to show/hide. Once it is done, use your component and open the dialog box. You will find the checkbox which upon checking shows the fields an on uncheck it hides the field. share, support, like and subscribe Subscribe : https://www.youtube.com/channel/UC5Lc...

MySQL 30 - INT Data Type
 
03:02
The last section of videos covered the string data types, now we are going to move on to the numeric data types. This video is going to discuss the INTEGER data types, or the INT data types. These data types are used to store whole numbers. That is, numbers without anything after a decimal. Just like with the TEXT data type, INT is broken up into multiple data types that can be used. It is actually broken up into 5 different data types. TINYINT, SMALLINT, MEDIUMINT, INT, BIGINT. Now, the confusing part here is the naming. That's because the only thing we have to compare this naming to is the TEXT data types. But they don't follow a consistent naming convention. For example, MEDIUMTEXT is larger than TEXT, but MEDIUMINT is smaller than INT. Additionally, there are 5 data types for the INT data type group, and lastly the biggest INT data type is called BIGINT whereas the biggest TEXT data type is called LONGTEXT. These are used to store exact values. What that means is that if you store a number and use it, you expect it to maintain precision. There are data types that are used for estimated values which we are going to discuss in more detail in an upcoming video. For now, let's focus on INT data types. You can find the exact storage limits for each of these, but here is some info: TINYINT - 255 SMALLINT - 65535 MEDIUMINT - 16 Million INT - 4 Billion BIGINT - Stinkin' a lot (18446744073709551615) Now note, in this situation, we will have to label each one of these as UNSIGNED. An unsigned number does not allow for negatives, but allows higher positive numbers. You can look up the INT data types to get the exact ranges for signed and unsigned. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 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!)
