SQL SELECT Statement Notes
Our SQL Select Statement notes offer an in-depth exploration of the SQL SELECT statement—essential for effectively querying and retrieving data from databases.
What is the SQL Select Statement?
The SQL SELECT statement is fundamental in SQL—allowing you to extract specific data from a database. This resource covers the core syntax required to write effective SELECT statements, including using SELECT FROM and the WHERE clause to filter data.
You learn about the AND operator and OR operator for combining multiple conditions and understand operator precedence to ensure your queries return the correct results.
Additionally, this resource explains how to use wildcard characters to search for patterns within your data and the BETWEEN AND clause for selecting values within a specific range. The IS NULL and IS NOT NULL conditions help you handle missing data, while various comparison operators allow precise data filtering.

Statistics
Before we can build machine learning algorithms or extract valuable insight from our data we need to transform the raw data into an understandable format and check its quality. In other words, we need to do data preprocessing, which requires statistical knowledge every step along the way. Therefore, learning statistics is a must-have skill when doing data science. In these free pdf course notes, we will be covering the fundamentals of statistics, the different types of distributions, confidence intervals and respective formulas, calculation of covariance and correlation, hypotheses testing, and much more
