HTML Tutorial - A Quick Overview for beginners

After this HTML Tutorial, you'll learn about basics of HTML and it's tag. It'll help you in developing and customizing applications and Web sites that make use of HTML. With our online HTML editor, you can run HTML code directly from your browser.

What is HTML-

HTML stands for Hyper Text Markup Language
An HTML file is a text file containing small markup tags
The markup tags tell the Web browser how to display the page
An HTML file must have an .htm or .html file extension
An HTML file can be created using a simple text editor as Notepad

HTML Tags-

The HTML tags are used to markup HTML elements
The HTML tags are surrounded by the two characters
The surrounding characters are called angle brackets
HTML tags normally come in pairs
The first tag in a pair is the start tag, the second tag is the end tag
The text between the start and end tags is the element content
HTML tags are not case sensitive

Simply open Online HTML Editor in the new tab Tab and copy HTML code from this page and just paste in the editor, then click on "Run Button" at top of the editor and see your result in the right panel.

Change Style of ADF TreeTable, Column, Data Cell, Selected Row using ADF Skin

Hello Everyone

In this tutorial, We'll learn to change look n feel of ADF tree table component using Oracle ADF Skin
Here I am using Departments and Employees table HR Schema to prepare the model and created tree Table using view link between Departments and Employees View Object

Increase Icon size of af:panelSpringBoard using ADF Skin

ADF Faces af:panelSpringBoard component shows af:showDetailItem in a fancy view using icons as the notation of showDetailItem

From Oracle Docs

The panelSpringboard control can be used to display a group of contents that belongs to a showDetailItem. An icon strip with icons representing the showDetailItem children along with the item's contents are displayed when in strip mode, and a grid of icons with no contents shown is displayed in grid mode. When the user selects an icon while the panelSpringboard is in strip mode, the panelSpringboard discloses the associated showDetailItem. When the user selects an icon while the panelSpringboard is in grid mode, this automatically causes the panelSpringboard to display in strip mode. Typically you would put one or more showDetailItem components inside of the panelSpringboard but you may also alternatively place a facetRef, group, iterator, or switcher inside of the panelSpringboard as long as these wrappers provide showDetailItem components as a result of their execution

I have added a panel springboard on the page and by default, it looks like this

PL/SQL Function

PL/SQL Function is same as PL/SQL Procedure, The only difference is that function must return a value and a procedure may or may not return a value

Saturday 7 April 2018

PL/SQL Procedure

Previously I have posted about PL/SQL Block structure , A piece of code that is organized in a properly defined sequence is called a block

PL/SQL provides two types of blocks

Function- A PL/SQL block that performs a task or set of tasks and returns a value

Procedure- A PL/SQL block that performs a task or set of tasks and may or may not return a value

PL/SQL Exceptions

An error that occurs during execution of the program is called exception, Like other programming languages, PL/SQL offers a way to catch these exceptions and handle them.

There are two types of exceptions in PL/SQL

System-Defined Exceptions
User-Defined Exceptions

Friday 23 March 2018

PL/SQL For Loop

PL/SQL FOR loop is used when we need to execute set of statements for the specific number of times and loop operates between the start and end counter values. The counter is always incremented by one and once the counter reaches to end integer value, the loop terminates

The syntax of PL/SQL FOR Loop is like this

FOR counter_variable IN start value.. end value LOOP

statements to execute

END LOOP;

PL/SQL While Loop

PL/SQL WHILE loop is used to execute statements as long as given condition is true and the condition is checked at the beginning of each iteration

The syntax of PL/SQL While loop is like this

WHILE condition

statements to execute

END LOOP;

PL/SQL Basic Exit Loop

In PL/SQL Basic Loop all statements inside the block are executed at least once before loop termination, Basic loop encloses statement between LOOP and END LOOP and there must be an EXIT or EXIT-WHEN condition to terminate the loop

The syntax of Basic Exit loop is like this

LOOP

statements to execute

EXIT; or EXIT-WHEN

END LOOP;

See these examples for better understanding

PL/SQL Loops , Iterative Statement in PL/SQL

Loops are used to repeat execution of a statement or a set of statements multiple times on base of a condition or expression
EXIT and EXIT-WHEN keywords are used to terminate the loop

EXIT- terminates the loop unconditionally and passes control to the next statement after the loop
EXIT-WHEN- terminates the loop when EXIT-WHEN clause is checked and if returns true then the loop is terminated and control is passed to next statement after the loop

The basic syntax of Loop in PL/SQL is like this

LOOP

Set of statements

END LOOP;

Thursday 22 March 2018

PL/SQL CASE Statement, Decision Making Statement in PL/SQL

Like real life in programming sometimes we need to execute some code on a specific condition, PL/SQL CASE statement allows us to execute a sequence of instructions based on a selector (A variable, function, expression etc)
and if selector value is equal to value or expression in WHEN clause then corresponding THEN clause will execute and process the statements

Wednesday 21 March 2018

PL/SQL Conditions, IF-ELSE Conditional Statement

Like other programming languages, PL/SQL supports decision making statements, These statements are also called conditional statement

Basic Syntax of IF-ELSE is like this in PL/SQL

IF (Condition 1)

THEN

Statement to execute (if condition 1 is true)

ELSIF (Condition 2)

THEN

Statement to execute (if condition 2 is true)

ELSE

Statement to execute (if condition 1& 2 both are false)

END IF;

For a better understanding of concept look at these examples

PL/SQL Variables and Constants

A variable in any programming language is the name of space where values are stored and controlled by our code/program

We can not use reserve keyword as a variable name
Variable length should not exceed 30 characters
The variable name consists of letters followed by other letters, dollar sign, underscore and numerals
The variable name should be clear and easy to understand

Here we'll learn how to declare and initialize variables in PL/SQL

The basic syntax for declaring a variable in PL/SQL is following

variable_name [CONSTANT] datatype [NOT NULL] [:= | DEFAULT initial_value]

Here variable_name is the identifier of variable and datatype is a valid PL/SQL datatype. CONSTANT and DEFAULT are keywords used to define constants and set default values of variables

Wednesday 7 March 2018

PL/SQL Basic Syntax, Block Structure and Anonymous block

PL/SQL is highly structured language and it's program units are written in the block of code, In this tutorial, we'll learn about basic syntax and the block structure of PL/SQL

A piece of code that is organized in a properly defined sequence is called a Block. A PL/SQL Block consists of 3 parts

DECLARE
<<declaration >>
--Declare Variables,Constants, Cursors and all elements

BEGIN
<<executable statements>>
--SQL, PL/SQL Commands

EXCEPTION
<<exception handling>>
--Code to handle the exception

END;

PL/SQL Tutorial - What is PL/SQL, Features and Advantages of PL/SQL

PL/SQL is developed by Oracle Corporation to increase/enhance capabilities of SQL, PL/SQL stands for Procedural Language extension to SQL . PL/SQL is highly structured and expressive language and because of its expressive syntax it is very easy to understand and learn

PL/SQL is integrated with Oracle Database and can be called from any other programming language. It is tightly integrated with SQL so it's easy to learn PL/SQL if you have knowledge of SQL

ADF Basics: Filter ViewObject data using getFilteredRows and RowQualifier

Sometimes we need to get filtered data from ViewObject using one or multiple conditions,
Though this is the very basic of framework yet new developers find it confusing.

There are two ways of filtering ViewObject

1. In this we apply WHERE clause on ViewObject and it affects resultSet data, Suppose we have Department ViewObject and we want to see data of DepartmentId 4 on page after filtering, for this viewCritera, bind variables comes in action
ADF Basics: Apply and Change WHERE Clause of ViewObject at runtime programmatically

2. In this user want to get filtered data (Rows) in code only without any effect on ViewObject resultSet (page data), Here I am discussing this point

We can get filtered data from view object using two methods-

R Data Types - Vectors, Matrices, Lists, Factors, Data Frames

Like other programming languages, R supports many different data types. You must have seen that variables are used to store data in a program and a data type is assigned to a variable and that variable can hold only that type of data. In this post, we'll learn about R data types and R objects. Basic data types in R programming are Numeric, Integer, Character, Logical and Complex and other than this R has some unique data types that are called R Objects.

Vectors in R

A Vector is basically a set of values of the same basic data type like numeric character etc. A vector in R is created using the c() function that represents a combination of elements. See this example

# A Numeric Vector
numeric_vector <- c(10, 20, 30)

# A Character Vector
character_vector <- c("a", "b", "c")

# A Boolean Vector
boolean_vector <-c(TRUE,FALSE,TRUE)

The output on R Console is

Matrices in R

R supports Matrices and a Matrix is a collection of data values in 2 dimensions of the same basic data type, R creates a matrix of values using a matrix() function. See this example Here c(1,2,3,4,5,6,7,8,9) is a numeric vector nrow is the number of rows in the matrix ncol is the number of columns in the matrix

#Create a matrix using Vector
test_matrix<-matrix(c(1,2,3,4,5,6,7,8,9), nrow=3, ncol=3)
#Print matrix on console
print(test_matrix)

The output on R Console is

Arrays in R

Arrays are the same as any other programming language and in R array is same as a matrix but it can have more than two dimensions. Array in R is created using array() function and uses a vector as input and dim value to create arrays. Here dim =c(2,2,4) means that 4 arrays will be created of 2x2.

#We have two vectors here
v1 <- c(1,2,3,7,8,9)
v2 <- c(4,5,6,10,11,12,13,14,15,16)

#Create array using vectors
test_array <- array(c(v1,v2),dim = c(2,2,4))

#print the array on the console
print(test_array)

The output on R Console is

Lists in R

A List is a set of values that can have the different basic data type, In R List is created using list() function.

#A list with different data types
#Declare a numeric vector
numeric_vector<-c(1,2,3)

#Create list 
test_list<- list("Ashish Awasthi", numeric_vector, 5.3)

#Print list
print(test_list)

The output on R Console

Factors in R

Factors are created using vectors as base and stores unique values as levels, In R Factor object is created using factor() function.

# Create a vector with duplicate values
emp_names <- c('James','Ram','James','Ashish','Ram','Ashish','James','Ram')

# Create a factor object using vector
factor_emp <- factor(emp_names)

# Print the factor object
print(factor_emp)

The output on R Console is

Data Frames in R

Data Frame is used for storing data in tables, and this tabular data can have multiple types of vectors like numeric, characters etc. Data Frame can be created using data.frame() function.

#A Character Vector
string_vector <-c("Ashish", "Awasthi","R")

#A Numeric Vector
numeric_vector <- c(10, 20, 30.5)

#A Boolean Vector
boolean_vector<- c(TRUE, FALSE, TRUE)

# Create the data frame using all 3 vectors
test_df <- 	data.frame(string_vector,numeric_vector,boolean_vector)

#Print result
print(test_df)

The output on R Console

Though this post gives an idea of using variables, In the next post, we'll learn more about using variables in R programming.

Cheers :) Happy Learning

Understanding Nested Application Modules in Oracle ADF

Application Module acts as a container for view Object and view Link business components that are used in a specific task. It provides data model and data control to show required information and perform action for the client
An application module represents a single transaction and owns one database connection that's why commit and rollback works for all view Objects inside an application module

Check for dirty (Uncommitted) data of current view port (page) on a button click or any event in ADF

Sometimes we need to check for uncommitted data on page and perform actions according to that, Suppose there is a button to navigate to another page but only if there is no uncommitted data in current page
We can use uncommitted data warning property of af:document to show an alert dialog but in that way, we can't execute our custom logic

Previously I have posted about checking dirty data of a transactional data control but in that, we need to check that for each data control separately that is rendering on page

ADF Basics| Tip to Hide af:inputListOfValues search popup at runtime

Hello All

Previously I have posted about a requiremnt of hiding af:inputListOfValues search icon using CSS
ADF Skinning | Hiding search icon of af:inputListOfValues using CSS & StyleClass

In that solution search icon doesn't appear on page but it is a part of JSF component tree so when user press TAB+SPACE after entering a value in lov component then search popup appears on screen as this action invokes search icon click event

Recently a Friend of mine came across another requirement that was not showing lov popup at all as only autoSuggest behavior was required , so for this first way is to use autoSuggest behavior in an af:inputText compoent using Lov bindings and second way is to short circuit component life cycle
