How to Write Basic SQL Statements (SELECT, FROM)


We can write a basic SQL statement using SELECT and FROM. The SELECT statement is the most common command in SQL.

5 Basic SELECT Statement Queries in SQL


Here are 5 Basic SELECT Statement Queries in SQL so you can begin pulling the information you need out of your database and tables! Query demos: 1) Select ALL from a table: SELECT * FROM table 2) Select certain columns from a table: SELECT column1, column2, column3 FROM table 3) Select all the unique or distinct rows in a column from a table. Another way to think of it is "removing duplicates": SELECT DISTINCT column FROM table 4) Change the displayed name of your columns by adding Aliases: SELECT column1 AS alias1, column2 AS alias 2 FROM table 5) Add arithmetic in your SELECT statement by using mathematical expressions: SELECT quantity*price AS total_price FROM table Get the Northwind Database: 🤍 Support the Channel: 1) Subscribe: 🤍 2) DataCamp: 🤍 3) Udacity: 🤍

We will not delve into strict and detailed technical definitions to explain how it works. What you need to know is there are a few types of programming out there – procedural (imperative), object-oriented, declarative, and functional. Although with some procedural elements, SQL is mainly regarded as a declarative programming language, it is nonprocedural. This means, while coding, you will not be interested in how you want the job done. The focus is on what result you want to obtain. An abstract example would best clarify what we mean here. When using a procedural language, such as C or Java, you must explicitly divide the solution of a certain problem into several steps. ► Consider hitting the SUBSCRIBE button if you LIKE the content: 🤍 ► VISIT our website: 🤍 🤝 Connect with us LinkedIn: 🤍 365 Data Science is an online educational career website that offers the incredible opportunity to find your way into the data science world no matter your previous knowledge and experience.

Best Way to Write Basic SQL Queries


SQL Server Query writing strategies is something I have yet to find in any book. When enthusiastic SQL students do this, they experience a revelation. The number of errors drops significantly and the speed at writing complex queries increases immediately. Knowing how to narrow down what we are looking for amongst a vast list of choices helps immensely. Grabbing the right tables first and then the fields second is akin to grabbing the right menu before ordering an item from it. In fact, one student named Tim took this back to his team of SQL developers and they immediately implemented this process. We are all used to following steps. Most of the time, actions are sequential from top to bottom or left to right. Other times we complete things in phases. The two phases we are going to use in this exercise apply to joining tables. This is easy to implement as we only need remember to organize first and clean up second. When visiting a new restaurant, we will ask to see the menu, because we want to see all they have to offer. The odds are that we might be interested in half of the items, but only need a few dishes for our group at the table. Looking at the menu is like starting a query with a ‘SELECT *’ statement. Once we have looked at all the fields, we narrow our choice(s) to only the items we want at the time. Sometimes restaurants have multiple menus. My favorite restaurant has a kids’ menu, an adult menu, a gluten-free menu and a drink menu. These menus were each gathered at our table. Ultimately, in my head, a selection was narrowed to what was needed. Phase I: Organize. When building a new query from many tables, we often find ourselves wondering, “Where do I start?” First, lay the steps out by identifying which tables contain the essential data. Second, get all the table joins working with a basic ‘SELECT *’ statement. Third, add any basic filtering criteria. Phase II: Itemize. Once all joins and criteria, such as SELECT, FROM and WHERE are working, we are ready for Phase II. This entails going back and changing our ‘SELECT *’ to an itemized SELECT field list as the final step. Let’s explore how this two-phase process of Organize and then Itemize can be a big time-saver. We are going to use one of the challenges from the last lab. In Lab 3.2 (Outer Joins), Skill Check 2, we needed to get four fields from two different tables. If we were to list all four desired fields and test one table at time, we will get an error as seen on the right side of the figure below. In the figure below we write a SELECT statement and part of the FROM clause. When completed, the FROM clause will have two tables, but for now we just want to get the Location table working. By using the ‘SELECT *’ strategy, we remove any possible errors from line 1. From there, we can focus on the more complicated logic used for joining tables together. We can add tables one at a time until everything is working. This is the Organize phase. NOTE: SELECT * never results in an Error message stating “invalid column name”, however; a SELECT list with itemized field(s) can have this error. After our query is organized and working, we can go back and itemize the SELECT field list to display only the fields that are necessary. This is done during Phase II (Itemize). The steps for this system are broken down as follows: Since SELECT is always the first statement in a query, it’s natural to want to write the field names before writing the FROM clause. However; we can save time and trouble by using the ‘*’ until the entire query is working properly. When this is complete, it is very easy to itemize the field list, with the confidence of knowing it will not cause any problems. Exercise: Simple membership for a club: Table1 (id_Member,name_Member, email_member, title, age, company) Table2 (id_Club,club_name, club_Location, address) Table3 (id_club, id_member,membership_date) Q1: Show all member names, email, age, and company from Table1 Q2: Show all club name, location, and address data Q3: Show member name, club name, club location (hint: Use joins and all 3 tables) You can find all other classes related to this video here: 🤍 Enroll Today & Get the First Month for only $1!

Learn how to write SQL Queries(Practice Complex SQL Queries)


Learn how to write SQL Queries(Practice Complex SQL Queries) In this video, I will explain the thinking behind writing an SQL query. We shall go through five different complex SQL queries and try to solve it. The intention is to practice complex SQL queries. The idea is to not just write SQL Queries but also to explain you the thinking behind how to choose a particular approach to solve a SQL query and how to choose different SQL functions or concepts to solve a problem. Link to my blog where I have posted all of these SQL Queries: 🤍 In this blog, you will find 9 SQL queries along with all the scripts to create the table, load data into these tables and also the solved SQL Queries. Out of these 9 SQL Queries, In this video, I have only solved 5 of them in order to reduce the video length. Timeline: 00:00 Intro 01:36 Intro about the blog 03:25 SQL Query to fetch duplicate records from a table using window function 09:27 SQL Query to fetch doctors working in same hospital using self join 15:55 SQL Query to fetch users who logged in consecutively 3 or more times 25:10 SQL Query to fetch days when the temperature was very cold for consecutively 3 or more days 36:13 SQL Query to fetch top 2 accounts with maximum patients per month Learning SQL Concepts and practically writing SQL queries are two different things. You may be familiar with the concept such as window function but until and unless you apply these concepts to write SQL queries, you will never truly understand SQL. May of the queries I am going to solve in this video, I will be using window function such as LEAD, LAG, RANK, ROW_NUMBER etc. However, some of the queries are solved using self join, sub queries or inner joins. The idea behind making this video, is to explain the thinking behind solving an SQL question. How to read the question and understand the problem statement and then analyze the existing data so that we can come up with an approach to write a query which can return the required result. These steps are very important in order for us to determine the different SQL concepts or functions to be used to solve the problem.
