About this course:
Our SQL certifications are intended to provide you with a foundation in the fundamentals of SQL and data manipulation so that you can begin analyzing it for data science purposes. You will begin to ask the right questions and provide good answers in order to provide valuable insights to your organization. This course begins with the fundamentals and assumes you have no prior knowledge or skills in SQL. It will build on that foundation by gradually requiring you to write simple and complex queries to assist you in selecting data from tables. You'll start working with different types of data, such as strings and numbers, and you'll talk about how to filter and narrow down your results.
What you’ll learn:
Determine the subset of data required from a column or set of columns and write a SQL query to limit the results to those results.
To filter, sort, and summarize data, use SQL commands.
Using the UNION operator, create an analysis table from multiple queries.
Manipulate strings, dates, and numeric data with functions to integrate data from various sources into fields with the appropriate format for analysis.
