Course Overview
SQL is a query processing language and Data Science is all about managing and manipulating data. This SQL for Data Science course gives you insights on how SQL is used in Data Science applications.
Intro to Clauses
This section discusses clauses. You shall understand to fetch data from a single table or by combining multiple tables using GROUP BY and HAVING statements.
Group By Statement
This section helps you understand GROUP BY statements in SQL and learn to group the elements based on conditions written after the query statement.
Demo for Group By Statement
This section will help you have practical exposure to group elements using GROUP BY clauses in the tables using the GROUP BY statement. It is handy to fetch data when the criterion is known.
Having Clause Statement
This section discusses the HAVING clause and explains the aggregation in the instances it is used.
Demo For having Clause
This section will demonstrate the HAVING clauses mentioned in the previous section with examples through which you will understand when and where to use the HAVING clause.
Alias in SQL
Alias is used to make table and column names more readable. You will learn to assign a temporary name to a table or a column in a table in this section.
Joins in SQL
This section briefs Joins in SQL and discusses statements that fetch all the results in different tables meeting the condition.
Types of Joins in SQL
This section defines Right Join, Left Join, Inner Join, Full Outer Join, Self Join, and Cross Join. You will understand how all of these joins return values based on the input statement and conditions.
INNER Join
You will learn to return the expected values in different tables based on the input condition using demonstrated examples using the INNER JOIN statement.
LEFT Join
This section briefs on how to return all the elements in the first table and the common elements in the other tables based on the input condition with demonstrated examples using the LEFT JOIN statement.
RIGHT Join
In this section, you will learn to return all the elements in the last table and the common elements in the other tables based on the input condition with demonstrated examples using the RIGHT JOIN statement.
FULL Join
You will learn to return all the values in both the tables based on the input condition, regardless of their commonalities, using demonstrated examples using the FULL JOIN statement.
SELF Join
You will learn to return the values of the same table depending on the input condition given by the user using demonstrated examples using the SELF JOIN statement.
Intro to Subquery
It is also called Sub-Selects or Nested Queries. This section helps you learn to write a query within another query.
Problem Statement
A problem statement is a scenario with defined elements to be achieved at the end of the query processing. You will learn to solve and work with problem statements in this section.
What is a Subquery?
A subquery is a nested query command within another query. It is also called Sub-Selects, and it returns the value that meets the requirements of both queries. You will understand the details in this section.
How Subquery Executes?
Each subquery is executed for every row of the outer query. A correlated subquery evaluated each row processed by the parent statements. SELECT, UPDATE, and DELETE statements are the parent statements. You will understand how a subquery executes in this section.
Type of Subquery
This section discusses single-row subquery, multiple row subquery, multiple columns subquery, correlated subquery, and nested subquery to understand the subquery concept.
Demo for Subqueries
This section will help you understand each subquery with demonstrated examples.
Introduction to SQL with Python
This section discusses how to use SQL queries written on Oracle in Python. You will also learn how SQL can alternatively be used directly in Python in the latter part of this section.
History of Python
This section comprehends the history of Python programming. It talks about the simplicity and user-friendly language exhibits with inbuilt libraries used to develop user-friendly applications.
Why Should You Learn Python?
Python is the most uncomplicated and sophisticated programming language, both easy to learn and use. It also reduces time spent on coding since it has built-in libraries to support high-end applications.
Why is Python So Popular?
Python is popular since it is coded like the English communication language, and it is simple to learn and code. You will understand other reasons why Python programming is prevalent in this section.
Installing Python
This section will demonstrate how to install Python with step-by-step explanations. You can follow the steps to install it on your PC.
MySQL with Python Demo
You will learn how to use MySQL with Python with a demonstrated sample problems.
Data Analysis using SQL
In this module, you will learn how to create and use a SQLite Database inside Jupyter Notebook, execute queries using Python, load queries result into Pandas Dataframes and perform simple data analysis using SQL and Python.
Connecting SQL to Power BI Tool
In this module, you will learn about using a Power BI Tool to connect with a SQL database, execute queries into the BI Model, building a simple dashboard and triggering a data refresh from SQL database.
