Different Types of SQL Operator

What is SQL?

The abbreviation of SQL stands for Structured Query Language. This language is used to perform several operations in the database. It is called Query language, which was designed in the year 1974. It allows users to perform several operations like modify, create, retrieve, delete and several other functions. SQL is used to perform operations in Relational Database System. From 1970 to 1986, it started and developed the wide number of commands helps execute the operation in Relational Database System.

SQL Operator

As the name indicates, SQL Operators are used to perform some arithmetic operations or some complex calculations. Usually, in SQL, the calculations are performed in the Where class. It is a conditional statement used for specific operations.

The SQL operators are classified into six types. They are,

1. Arithmetic Operator
2. Bitwise Operator
3. Comparison Operator
4. Compound Operator
5. Logical Operators
6. String Operators

Arithmetic Operator

The usual arithmetic operator includes addition, Subtraction, multiplication, division and modulus operator.

Addition-It operates by adding two numbers

SELECT 11+11;

The ‘+’ symbol adds the two numbers.

Subtraction-It operates by subtracting the two numbers

SELECT 11-11;

The ‘-‘ symbol denotes subtracting the values from one another.

Multiplication-It operates by multiplying two numbers

SELECT 11*11;

This ‘*’ symbol resembles the multiplication of two values

Division-It operates by dividing one number by another

SELECT 11/11;

This ‘/’ symbol resembles the dividing the number by another number

Modulo-This operation is called modulus or remainder

SELECT 11%11;

This ‘%’ operates by returning the remainder while dividing each other.

Bitwise Operator

The bitwise operations are performed between two values or expressions. It includes Bitwise AND (&), Bitwise OR (|, ^), Bitwise Not (~).

Bitwise AND (&)

The bitwise AND operator compares the two values and returns the result according to that.

DECLARE @BitOne BIT =5

DECLARE @BitTwo BIT=6

Select @BitOne & @BitTwo;

The result will be displayed as 30.

DECLARE @BitOne BIT =1

DECLARE @BitTwo BIT=0

Select @BitOne & @BitTwo;

The result will be displayed as 0.

The bitwise AND Assignment (&=) is another type of operation performed in Bitwise AND.

If both the values are 1, the result is 1. If one is 0, the result is 0.

Bitwise OR (|, ^)

The bitwise OR operator represents the value in the format of if both the numbers are 0, then the result is 0. If one is 1, the result is displayed as 1.

DECLARE @BitOne BIT =1

DECLARE @BitTwo BIT=0

Select @BitOne | @BitTwo;

The result is displayed as 1.

The other type of operators performed are (|=), (^), that is, Bitwise OR Assignment, Bitwise exclusive OR, which operates similar to Bitwise OR, but it determines the variable’s value when the result is returned.

The Bitwise Not operator (~) displays the result as 0 if the value is 1 and 1 if the value is 0. It does the process of inversion.

Comparison Operator

As the name denotes, it performs the task by comparing each value to check whether they are the same. The comparison operator is subdivided into the following types.

Equal to (=) It checks whether the given value is equal to the assigned value.

Not equal to! = It checks whether the given value does not equal the assigned value.

Greater than > this operations check whether the value is greater than the assigned value

Not greater than!> this operation checks whether the value is not greater than the assigned value

Less than < It checks whether the value is lesser than the assigned value.

Not lesser than! < It checks whether the given value is not lesser than the assigned value.

Greater than equal to >= It checks whether the given value is not lesser than the assigned value

Lesser than equal to <= It checks whether the given value is not greater than the assigned value

<>Not equal to   It checks whether the two values are not equal.

Compound Operator

The compound operator is subdivided into,

+=   Add equal

-=   Subtract equal

*= Multiply equal

/=   Divide equal

%= modulo equals

Logical Operators

The logical operators are sub-divided into the following types,

ALL

ANY or SOME

AND

BETWEEN

EXIST

IN

LIKE

NOT

OR

IS NULL

String Operators

Concatenation is mainly used in string operators to combine two strings.

The string operators are classified as

+ String Concatenation

+= String Concatenation Assignment

% Wildcard

[] Character matches

[^] Character not to match

_(Wildcard match one Character)

Summary

The above article describes the various types of operators and their functions in SQL in detail. Each has its unique functions and properties.

What are the local and global variables in the Python programming language?

What are the local and global variables in the Python programming language?

In this tutorial, we will cover the local and global variables of the Python programming language but before moving deep down the concept of Local and Global variables, first let’s discover.

• What is Python programming language?
• What is Variables in Python programming language?

What is Python programming language?

Python programming language is usually considered another important programming language similar to other languages such as Java, C, C++, etc.

Python programming is usually defined as the most powerful programming language and the general-purpose programming language, which is used to develop web applications, data science, the creation of software prototypes, and so on. It is considered a simple language for beginners because it has a simple syntax and easy language compared to the other programming languages.

Features of the Python Programming Language:

• Python programming language is the best programming language to handle the huge amount of raw and unstructured forms of data.
• Python programming language is easy to debug because it is an interpreted language, i.e., code is executed line by line.
• Python programming language is usually encapsulated with huge library support.
• Python is a cross-platform programming language that makes sense that the program of the python programming language can run on any platform.
• Python programming language is usually a multiprogramming language because it supports all conventional language features, including C and C++.
• Python programming language serves as the best programming language for developing applications effectively and efficiently. 

Variables in Python programming language

Variables are generally considered one of the most important terminologies used in any programming language. Variable is generally defined as the name assigned to a storage part (area) that the program usually uses to manipulate. A variable type is used to determine the size and the layouts for the memory of variables.

It also determined the values of the range that need to be stored inside the particular memory and the nature of the operations which can be applied to that variable.

In general, there are two types of variables present in the Python programming language that are as follows:

1. Local variables.
2. Global Variables

Local Variable in Python programming language:

Local variables are generally initialized inside a particular defined function or a block, and it is usually bounded to that particular function only, which means the local variable can be only and only be accessed inside the defined function. It cannot be used outside the defined function. The important key point related to the local variable is that the local variable exists until and unless the block of the particular function is under execution. As soon as the execution gets completed, the variable gets destroyed automatically.

A local variable can be declared with the help of the keyword that is “Local”.

Creation of Local Variable:

Generally, we can declare a variable inside a function for creating a local variable.

Example:

def harish():

x= “ My name is Mohammed Harish Askeen”

print (x)
harish ()

Output:

The output for the above respective code for creation of local variable is as follows:

If a programmer tries to use the above local variable outside the function then let us see with the example what happen.

Example:

def harish () :

x = “ My name is Mohammed Harish Askeen”

harish ()

print (x)

Output:

The outputs for the above respective code are as follows:

Global Variable in Python programming language:

The global variable is generally considered an important variable type in the Python programming language. Global variables are usually defined as the variable that is defined outside any block or the function, and that can be accessed throughout the program, which means inside and outside of every function.

A Global variable can be declared using the keyword “Global”. 

Defining and accessing of the Global variable:

Example:

# This function uses global variables.
x=” My name is Mohammed Harish Askeen”

   def askeen();

print(“ x inside:”,x)

askeen()

print(“ x outside:”,x)

Output:

The output for the above respective code is as follows:

Local Variable v/s Global Variable

Key differences between the Local variable and the Global variable:

The key differences between the Local variable and the Global variable are as follows:

1. If the Local variable is not initialized, then, in that case, a garbage value is stored. At the same time, in the Global variable, if it is not initialized, then in that particular case, zero is stored as default.
2. The local variable is created when the desired function starts the execution and is destroyed or lost when the functions get terminated. In the Global variable, it is created before the global program execution gets started and destroyed or lost when the desired program gets terminated.
3. In the Local variable, the data sharing is not possible because the data of the local variable can be accessed by only one function. In contrast, data sharing is possible with the Global variable as the multiple functions can access the same global variable.
