Free Download 1Z0-171 - Oracle Database 23Ai Sql Associate Published 9/2024 MP4 | Video: h264, 1920x1080 | Audio: AAC, 44.1 KHz Language: English | Size: 7.71 GB | Duration: 15h 7m The SELECT statement, functions and more. Oracle Database 19c, 21c, 23c, 23ai using Oracle SQL Developer. 1Z0-171 exam. What you'll learn Relational Database Concepts Retrieving Data using the SQL SELECT Statement and Restricting and Sorting Data Using Functions Displaying Data from Multiple Tables, including using SET operators Using Subqueries to Solve Queries Managing Indexes Synonyms and Sequences Manage tables and their relationships using DDL and DML statements Control User Access Managing Objects with Data Dictionary Views and Data in Different Time Zones Requirements You need to know how to use a computer, and hopefully know how to use a spreadsheet. No prior knowledge of Oracle SQL Database or any other database required - although the more knowledge you do have, the better. To install Oracle SQL Database on your computer, you will need a 64-bit machine. Oracle SQL Database cannot easily be installed on the Mac OS. If you wish to install it on a Mac, you will need either to dual boot into Windows or be running Parallel Desktop. You don't even need Oracle SQL Database installed - I'll show you have to install it on your computer for free! Why not have a look at the curriculum below and see what you can learn? Description This course is the foundation for the Oracle Database SQL 1Z0-171 certification. It covers the SELECT statement in detail, with additional requirements for controlling user access.We'll install for free Oracle Express Edition and Oracle SQL Developer. Then we'll take a look at the 6 prin[beeep]l clauses of the SELECT statement: SELECT, FROM, WHERE, GROUP BY, HAVING and ORDER BY.Then we'll start creating tables, but find that we can't get very far without understanding data types. We'll then look at string, date and number types and functions, together with looking at functions converting between them.We'll revisit the SELECT statement and go into more detail. We'll create tables and JOIN them together. Once you have finished this session, you should be secure in your knowledge of the 6 prin[beeep]l clauses of the SELECT statement, the most important part of Oracle SQL.We'll then looking for missing data, and find out how to delete and update data. We'll look at the difference between implicit and explicit transactions, and various constraints, including primary and foreign keys.We'll start off by saving our queries in views. Then we'll combine tables, not by adding additional columns using JOINS, but adding additional rows such Oracle SQL set operators such as UNION, INTERSECT and MERGE.We'll add totals to our SELECT queries. We'll then look at subqueries, and how you can add them into the FROM, SELECT and WHERE clauses, and also into the WITH clause. We'll also look at Oracle SQL self-joins, which are useful when you have hierarchies.Finally, TIME ZONE and INTERVAL data types and functions. We'll then have a look at SEQUENCEs and INDEXes, together with how these are shown in the Data Dictionary. We'll then create new users, and assign privileges and roles to them, and we'll finish with the last few requirements for the exam.No prior knowledge is required - we'll even install Oracle Database and Oracle SQL Developer on your computer for free!Once finished, you will know what how to manipulate numbers, strings and dates, and create database and tables, create tables, insert data and create analyses, and have an appreciation of how they can all be used in Oracle SQL.
