SQL Joins Explained with example 👇🏻 1️⃣ Left Join: Returns all records from the left table and matched records from the right table, with NULLs for unmatched right table records. Example 👇🏻 SELECT * FROM Employees LEFT JOIN Departments ON Employees.DeptID = Departments.DeptID; 2️⃣ Right Join: Returns all records from the right table and matched records from the left table, with NULLs for unmatched left table records. Example 👇🏻 SELECT * FROM Employees RIGHT JOIN Departments ON Employees.DeptID = Departments.DeptID; 3️⃣ Inner Join: Returns only the records that have matching values in both tables. Example 👇🏻 SELECT * FROM Employees INNER JOIN Departments ON Employees.DeptID = Departments.DeptID; 4️⃣ Full Outer Join: Returns all records when there is a match in either left or right table, with NULLs for unmatched records in the other table. Example 👇🏻 SELECT * FROM Employees FULL OUTER JOIN Departments ON Employees.DeptID = Departments.DeptID; 🏆 Follow @datasciencebrain #dsbrain for more amazing Data Science resources and News 📌Tag your friends who would like to know about this • • • • • #data #datascience #dataanalytics #dataanalysis #dataanalyst #datascientist #datacleaning #statistics #python #sql #dataengineering #engineering #pandas #datavisualization #machinelearning #deeplearning #datasciencejobs #datascienceinternship #datascienceroadmap #learndatascience #learndataanalytics #datascienceinterview #datasciencebooks

What SQL topics would you like to see next? There are 4 common types of joins to become familiar with. There are many more types of joins, but these four are the key to understanding the rest: 1. LEFT JOIN 2. RIGHT JOIN 3. INNER JOIN 4. FULL JOIN The syntax of the join is as follows: SELECT t1.col1, t1.col2, t2.col1, t2.col2 FROM table1 as t1 JOIN table2 as t2 ON t1.col1 = t2.col1 - - assuming t1.col1 and t2.col1 have the same fields Follow @data.bell for the rest of the JOIN series.

⚡️SQL in 60 Episode 1: How to do an anti join ⬇️ Comment “SQL” for my free basic SQL course to get started!! Anti Joins are one of the most common interview questions for data science and analytics interviews. Very rarely are they explicitly called “anti joins” in the real world— most of the time people just use them without knowing the name. But there are so many business questions that require using this concept such as: ✨What customers have NOT placed an order? ✨What products do NOT have inventory? ✨What sales reps have NOT made a sale? The syntax is just like a left join with a slight variation in the WHERE clause to filter for ONLY the rows that DO NOT have a match in the second table. This helps us identify the rows in the left table that are NOT in the right table. Here’s the basic syntax: select * from table1 t1 left join table2 t2 on t1.id = t2.id where t2.id is null What does the WHERE clause do in an anti join? #sql #data #dataanalytics #datascience #womenindata #womenintech
