Organizations typically store their most critical information—the information used to manage day-to-day operations—within a database. The ability to retrieve and analyze this information is essential to the functioning of the organization. Structured Query Language (SQL) is the primary language used to accomplish such tasks. Essentially, SQL is the language you use to interact with a database.

The ability to write SQL is an essential job skill for those who need to manage large volumes of data, produce reports, mine data, or combine data from multiple sources. Even if someone else on your team creates reports for you, having a fundamental understanding of SQL querying will help you ask the right questions and know what you're looking for in your data analysis tools.

In today's competitive environment, information is one of the most important factors in determining the success of an organization. If you are able to manage and retrieve information efficiently, you can streamline the organization's processes and give it a competitive edge. Some data analysis tasks may require that you query multiple tables simultaneously or create complex views of data.

In this course,  you will start by learning the basic SQL syntax and then move on to learning advanced querying techniques, such as writing nested queries, using JOINs to combine data from multiple tables, summarizing query results, using advanced filtering, and using views to simplify repetitive querying tasks. You will also learn how to perform common database administration tasks such as duplicating tables, modifying table structures, inserting, updating, or deleting data, and indexing tables to optimize query performance. You will also learn how to work with multiple tasks as a transaction.

Course Objectives

In this course, you will compose SQL queries to retrieve desired information from a database.

You will:

  • Connect to the SQL Server database and execute a simple query.
  • Include a search condition in a simple query.
  • Use various functions to perform calculations on data.
  • Organize the data obtained from a query before it is displayed onscreen.
  • Retrieve data from multiple tables.
  • Export the results of a query.
  • Use nested queries to generate query output.
  • Manipulate table data by inserting and updating records in a table and deleting records from a table.
  • Manipulate table structure.
  • Create views, manipulate data through views, modify the view structure, and drop views.
  • Create indexes on table columns and drop inefficient indexes.
  • Mark the beginning of a transaction, roll back a transaction, and commit a transaction.
