    For the past 3 days, I have been trying to learn the basics of SQL from different channels. This video is, so far, the best in explanation. I love the fact that you make SQL sound so simple and easy to understand. I would definitely recommend you to other people who want to go into the data analytics business. Thank you so much.

    🎯 Key points for quick navigation:
    00:00 *📚 SQL Overview*
    - SQL is a widely used programming language for managing relational databases.
    - It allows interaction with databases for reading, writing, modifying, and analyzing data.
    - SQL is essential for various roles including developers, analysts, engineers, and scientists.
    03:18 *🏗️ SQL DDL Commands*
    - Data Definition Language (DDL) commands in SQL include CREATE, ALTER, DROP, and TRUNCATE.
    - These commands are used to define and manage database structures like tables and views.
    - DDL commands ensure database objects are created, modified, or deleted as required.
    08:21 *🛠️ SQL DML Commands*
    - Data Manipulation Language (DML) commands in SQL include INSERT, UPDATE, and DELETE.
    These commands are used to manipulate data within database tables.
    - DML commands facilitate adding, modifying, or removing data entries.
    13:00 *📊 SQL Constraints*
    - Constraints like CHECK, NOT NULL, UNIQUE, PRIMARY KEY, and FOREIGN KEY ensure data integrity.
    - They impose rules on data columns to maintain consistency and accuracy.
    - Constraints prevent invalid data insertion and enforce relational integrity.
    21:16 *📑 SQL SELECT Queries*
    - SELECT queries retrieve data from one or more tables based on specified conditions.
    - These queries form the core of SQL for fetching, analyzing, and reporting data.
    - SQL SELECT statements are flexible and can include complex joins and filtering conditions.
    22:40 *📚 Introduction to SQL basics and practice queries*
    - Introduction to writing SQL select queries covering operators, group by statements, SQL joins, subqueries, and aggregate functions.
    - Overview of database tables designed to simulate a school database environment.
    24:31 *📊 Basic SQL select queries and operators*
    - Explanation of the SQL `SELECT` statement using `SELECT * FROM students` to fetch all records.
    - Detailed overview of SQL operators: equal to, not equal to, less than or equal to, greater than or equal to, and their practical uses in filtering data.
    27:05 *🔄 Sorting and filtering data in SQL*
    - Demonstration of the `ORDER BY` clause for sorting query results.
    - Practical application of the `BETWEEN` operator for filtering salary ranges.
    - Explanation of the `IN` and `NOT IN` clauses for filtering data based on multiple conditions.
    30:21 *🧩 Logical operators and conditional queries in SQL*
    - Detailed use of `AND` and `OR` operators in SQL queries for combining multiple conditions.
    - Examples of how `AND` requires all conditions to be true, while `OR` retrieves results if any condition is true.
    35:05 *🎯 Conditional logic with CASE statements in SQL*
    - Utilization of the `CASE` statement to create conditional logic in SQL queries.
    - Example of using `CASE` to categorize salaries into high, average, and low categories based on predefined conditions.
    36:28 *🌐 SQL joins: INNER JOIN and WHERE clause*
    - Explanation of SQL joins using `INNER JOIN` and the `WHERE` clause for filtering data across multiple tables.
    - Comparison of JOIN syntax using aliases for better readability and debugging in complex queries.
    44:14 *📊 Union and Union All in SQL*
    - Understanding the usage of `UNION` and `UNION ALL` operators in SQL.
    - `UNION` combines results and removes duplicates, while `UNION ALL` combines results without removing duplicates.
    - Ensure columns and their data types match when using `UNION`.
    47:20 *📊 Group By in SQL Queries*
    - Explanation of the `GROUP BY` statement in SQL to aggregate data.
    - Use `GROUP BY` to group data based on specific column values.
    - Essential for performing aggregate functions like `COUNT`, `SUM`, `AVG` on grouped data.
    52:08 *📊 Using Group By with Having Clause*
    - How to filter grouped data using the `HAVING` clause in SQL.
    - `HAVING` clause is used with `GROUP BY` to apply conditions to aggregated data.
    - Example: Filtering classes with more than 100 students using `GROUP BY` and `HAVING`.
    54:12 *📊 Subqueries in SQL*
    - Introduction to subqueries and their role in SQL queries.
    - Subqueries are queries nested inside another query.
    - Useful for complex filtering and retrieving specific data subsets.
    58:49 *📊 Aggregate Functions in SQL*
    - Understanding aggregate functions (`AVG`, `SUM`, `MIN`, `MAX`) in SQL.
    - Aggregate functions perform calculations on a set of values and return a single value.
    - Practical examples include calculating average salary or total salary in a dataset.
    01:02:08 *📊 Inner Join and Outer Join in SQL*
    - Explanation of `INNER JOIN` and `OUTER JOIN` in SQL.
    - `INNER JOIN` retrieves records that have matching values in both tables.
    - Types of `OUTER JOIN`: `LEFT`, `RIGHT`, and `FULL`, for retrieving unmatched records from one or both tables.
    01:06:21 *📊 Understanding Left Outer Join*
    - Understanding left join in SQL,
    - Left join fetches all records from the left table and matching records from the right table.
    - Non-matching records from the left table are also included with NULL values for the right table columns.
    01:07:54 *🔄 Exploring Right Outer Join*
    - Exploring right join in SQL,
    - Right join retrieves all records from the right table and matching records from the left table.
    - Non-matching records from the right table appear with NULL values for the left table columns.
    01:09:17 *🌐 Applying Full Outer Join*
    - Applying full outer join in SQL,
    - Full outer join combines results of both left and right outer joins.
    - It retrieves all matching records, along with non-matching records from both left and right tables.

      I don't prefer TABLEAU as it's 4 -14 days trial version ..i tried tableau public version software .. loading data is dead slow ..

  • @ignacioa3698
    @ignacioa3698 Год назад +2

    Great stuff!!!!!! I know you have other videos which shows more detailed explanations and logic on the different JOINS. HOWEVER, in showing your JOINS examples in this video best to show the original tables (along with the table original columns) somewhere else in the screen off to the side so it's better to follow along, actually we can see table and columns names of the tables, and try to visualize it. And makes it better to follow along and actually try to replicate the exercises as well.

  • @bhababajracharya7401
    @bhababajracharya7401 3 года назад +1

    Very nice video for SQL beginners. My major confusion is when we use " join... on ..." mthod to join the tables and we need to write the "where" clause on multiple join tables like "t1 join t2 on.. where" and again "join t3 on... where". This yields very different result. where do we exactly write all the "Where" clause at the end of all the joins or on the respective joins itself.

    • @techTFQ
      @techTFQ  3 года назад +1

      Where clause should be after all the joins..
      You don’t put where in between the joins..
      I have created separate video series covering joins where I have explained all the process.. perhaps you can watch that

    Hi Thoufiq, it was a very great session to cover all SQL concepts in one go, just a quick suggestion since you're using PostgreSQL, I was expecting you show basics of using it like creating database, creating tables, how to save them and find them later on the tool and all...since we don't know how to use it. Thanks!
