Most Common MySQL Queries
By BABA NANAK INSTITUTE OF TECHNOLOGIES 16-Jun-2021
1. Create Table
You would not use the create table query every time the script executes in normal scenarios. However, when you start building an application, you need to create database tables. To do so with a primary key, you can use the following query.
CREATE TABLE 'emp' (
'id' INTEGER UNSIGNED NOT NULL AUTO_INCREMENT,
'name' VARCHAR(45) NOT NULL,
'lastname' VARCHAR(45),
'dept' VARCHAR(45) DEFAULT 'sales',
PRIMARY KEY ('id')
)
ENGINE = InnoDB;
The above query creates a table "emp" in the selected database. We will have an "id" column as auto increment and with a PRIMARY KEY constraint, which ensures an incremented integer value is added every
While Loops With Python
By AIC Computer Education 06-Mar-2021
Python provides following types of loops to handle looping requirements. Python provides three types of loops. While all the ways provide similar basic functionality, they differ in their syntax and time to check condition.
While Loop: while loop executes a block of statements repeatedly until a given a condition is true. when the condition becomes false.the line immediately after the loop in program is executed.
Syntax
i = 1
while i < 6:
print(i)
i += 1
Use else statement with while loops: while loop executes the block until a condition is satisfied. When the condition becomes false, the statement right after the loop get executed.else clause
Objective-C
By CCERT 18-Aug-2020
Objective-C is a general-purpose, object-oriented programming language that adds Smalltalk-style messaging to the C programming language. It was the main programming language supported by Apple for macOS, iOS, and their respective application programming interfaces (APIs), Cocoa and Cocoa Touch, until the introduction of Swift in 2014.
The language was originally developed in the early 1980s. It was later selected as the main language used by NeXT for its NeXTSTEP operating system, from which macOS and iOS are derived. Portable Objective-C
C++ (Programming Language)
By CCERT 18-Aug-2020
C++ (/ˌsiːˌplʌsˈplʌs/) is a general-purpose programming language created by Bjarne Stroustrup as an extension of the C programming language, or "C with Classes". The language has expanded significantly over time, and modern C++ now has object-oriented, generic, and functional features in addition to facilities for low-level memory manipulation. It is almost always implemented as a compiled language, and many vendors provide C++ compilers, including the Free Software Foundation, LLVM, Microsoft, Intel, Oracle, and IBM, so it is available on many platforms.
C++ was
PHP (Programming Language)
By CCERT 18-Aug-2020
PHP is a general-purpose scripting language that is especially suited to web development. It was originally created by Danish-Canadian programmer Rasmus Lerdorf in 1994; the PHP reference implementation is now produced by The PHP Group. PHP originally stood for Personal Home Page, but it now stands for the recursive initialism PHP: Hypertext Preprocessor.
PHP code is usually processed on a web server by a PHP interpreter implemented as a module, a daemon or as a Common Gateway Interface (CGI) executable. On a web server, the result of the interpreted
Python
By CCERT 18-Aug-2020
Python is an interpreted, high-level, general-purpose programming language. Created by Guido van Rossum and first released in 1991, Python's design philosophy emphasizes code readability with its notable use of significant whitespace. Its language constructs and object-oriented approach aim to help programmers write clear, logical code for small and large-scale projects.
Python is dynamically typed and garbage-collected. It supports multiple programming paradigms, including structured (particularly, procedural), object-oriented, and functional programming.
Java
By CCERT 18-Aug-2020
Java is a general-purpose programming language that is class-based, object-oriented, and designed to have as few implementation dependencies as possible. It is intended to let application developers write once, run anywhere (WORA), meaning that compiled Java code can run on all platforms that support Java without the need for recompilation. Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of the underlying computer architecture. The syntax of Java is similar to C and C++, but it has
