Learn the key concepts of Structured Query Language (SQL), and gain a solid working knowledge of this powerful and universal database programming language.
In this course, you'll learn about the basic structure of relational databases and how to read and write simple and complex SQL statements and advanced data manipulation techniques. First, you'll learn about the traditional database structure, the structure and history of the relational database, and what structured query language (SQL) is and how it relates to the relational-database structure.
Next, you'll discover how to use SQL to sort and retrieve data from tables and how to use SQL to filter retrieved data. You'll learn how to reformat retrieved data with calculated fields and how to merge columns and create alternate names for columns. You'll also learn how to gather significant statistics from data using aggregate functions, and you'll see how to extract data from multiple tables simultaneously using joins and subqueries. In addition, you'll learn how to manipulate data using the INSERT, UPDATE, and DELETE statements.
We'll also cover how to use SQL to create and maintain tables, and you'll learn how to create and use views to simplify complex queries, summarize data, and manipulate data stored in tables. You'll discover how transaction processing, constraints, and indexes are implemented in SQL. And finally, you'll discover how stored procedures, triggers, and cursors are implemented in SQL.
By the end of this course, you'll have a solid working knowledge of structured query language. You'll feel confident in your ability to write SQL queries to create tables; retrieve data from single or multiple tables; delete, insert, and update data in a database; and gather significant statistics from data stored in a database.

Studies prove, time and again, that college-educated workers earn more than those with only a high school qualification. College graduates often enjoy additional benefits, including greater job opportunities and promotions. Though the proof for greater earning potential exists, some might wonder whether the cost of the education warrants the overall expense in the long run.
College Graduate vs. Non-Graduate Earnings
The National Centre for Education Statistics (NCES) analyses employee earnings data biennially, according to education level. Findings indicate that workers with a qualification earn significantly more than those without. Since the mid-1980s, education has played a large part in potential wages, with bachelor's degree holders taking home an average of 66% more than those with only a high school diploma do. While college-educated workers' wages have increased over the past two decades, those with only a high school education have seen decreases in annual salaries in the same time period (nces.ed.gov).
