Develop Advanced SQL Functions—Create subqueries and logic statements
SQL Level II dives into the functions and features that make SQL easier to use. Find rows that meet specific criteria with views and subqueries. Write advanced functions and logic statements with conditions. Manipulate data to facilitate scanning and increase readability of reports.
Like our other SQL courses, SQL Level 2 ends with a project-based lab. Activities completed in SQL Levels 1 and 2 help students retain and build upon skills. Labs in SQL Level II require students to create and edit views, write subqueries and logic and date functions, and more.
At the end of this course, you’ll be able to do the following:
Save queries to a server for all users to utilize
Create views to restrict data and draw up reports
Identify when and how to write subqueries to maximize efficiency
Perform count, sum, average and other math functions
Use data conversion functions to facilitate scanning

In-Depth Course Overview
In SQL Level 2, you’ll learn tools and techniques related to the following commands:
Create Views - Create views to review a subset of data, and learn the advantages and restrictions when working with SQL views
Subqueries - Learn how to write subqueries and the benefits of using them instead of inner and outer table joins
Math Functions and Logic Statements - Calculate basic math functions and write logic statements to find data that meets certain conditions
Data Conversion Functions - Use data conversion functions to display numbers as text, round decimals, and format other data types
SQL Level 2 begins with lessons on SQL views. Start by reviewing the benefits and disadvantages of using views. For example, if variables are used in queries, then views won’t work. Next, you’ll jump into subqueries. Although subqueries can produce the same information as inner and outer joins, it can do so more quickly and efficiently.
Following subqueries students will learn how to write commands for basic math functions. Use SQL commands to add, subtract, multiply, and divide fields or calculate sums, averages, and counts. With logic statements, such as “CASE WHEN THEN” statements, you’ll group data into specific categories.
Finally, you’ll learn how to use data conversion functions to manipulate data types and appearance. For example, apply commas, decimals, and dollar signs to numerical data types to make it easier to scan prices in a report. The course ends with a lab, in which you’ll practice using the commands described above.
