SQL IMPORTANT QURIES

 mysql> SHOW DATABASES; +----------+ | Database | +----------+ | mysql    | | test     | | tmp      | +----------+ The mysql database describes user access privileges. The test database often is available as a workspace for users to try things out. The list of databases displayed by the statement may be different on your machine; SHOW DATABASES does not show databases that you have no privileges for if you do not have the SHOW DATABASES privilege. See Section 13.7.7.14, “SHOW DATABASES Statement”. If the test database exists, try to access it: mysql> USE test Database changed USE, like QUIT, does not require a semicolon. (You can terminate such statements with a semicolon if you like; it does no harm.) The USE statement is special in another way, too: it must be given on a single line. You can use the test database (if you have access to it) for the examples that follow, but anything you create in that database can be removed by anyone else with access to it. For this reason, you

Chatgpt

 What is Chat GPT And How Can You Use It? Chat GPT is a large language model chatbot developed by Open AI based on GPT-3.5 . It has a remarkable ability to interact in conversational dialogue form and provide responses that can appear surprisingly human . Large language models perform the task of predicting the next word in a series of words . Reinforcement Learning with Human Feedback (RLHF) is an additional layer of training that uses human feedback to help Chat GPT learn the ability to follow directions and generate responses that are satisfactory to humans. Who Built Chat GPT? Chat GPT was created by San Francisco-based artificial intelligence company Open AI . Open AI Inc. is the non-profit parent company of the for-profit Open AI LP .Open AI is famous for its well-known DALL·E, a deep-learning model that generates images from text instructions called prompts .The CEO is Sam Altman, who previously was president of Y Combinator.

What Is Python Used For

 Python is an interpreted, object-oriented, high-level programming language with dynamic semantics developed by Guido van Rossum . It was originally released in 1991 . Designed to be easy as well as fun, the name "Python" is a nod to the British comedy group Monty Python. Python has a reputation as a beginner-friendly language, replacing Java as the most widely used introductory language because it handles much of the complexity for the user, allowing beginners to focus on fully grasping programming concepts rather than minute details. Python is used for server-side web development, software development, mathematics, and system scripting, and is popular for Rapid Application Development and as a scripting or glue language to tie existing components because of its high-level, built-in data structures, dynamic typing, and dynamic binding. Program maintenance costs are reduced with Python due to the easily learned syntax and emphasis on readability. Additionally, Python's s
