Introduction to SQL Queries Live Online Learning Courses
This one-day SQL (Structured Query Language) workshop will give you a thorough grounding in the basics of writing SQL SELECT statements. This is a practical hands-on workshop which covers ANSI SQL using MS SQL Server as the example relational database.
The workshop typically uses MS SQL Server and SSMS, so it is important that you have this set up on your own computer prior to the training. It is possible to adapt the workshop for MySQL, for Access or for BigQuery. Please let us know the version you use before booking.
Please note, Introduction to SQL Queries is only available for private groups. Please get in touch for more information, pricing and availability.
This online workshop runs from 9.30am to approximately 4.30pm with regular breaks. It is possible to split the workshop into 2x ½ days. Please let us know your preference. A maximum of six attendees means there is plenty of opportunity for you to ask questions.
What you will learn
By the end of this course you will be able to write SQL SELECT statements confidently. You will be able to retrieve data from one or more tables, using a variety of criteria. You will be able to sort the data and perform row and summary calculations.
Session 1 - Getting Started and Writing Basic SQL Statements
We start with an overview of relational databases whilst examining the training database. We will get comfortable with the tool we use during the training to write the queries (the training course typically uses Microsoft SQL Server and SSMS).
This session practices writing queries that select data from one table. We learn how to specify the columns we need and how to sort the data. We then focus on the WHERE clause to limit the data returned.
The key topics trained are:
- The syntax of the SELECT statement
- Using the Distinct keyword
- Order by
- Examples of WHERE criteria including wildcards, comparison operators and
BETWEEN, LIKE and IN
Session 2 – SQL Joins
There are a number of different ways that data from different tables can be queried using JOINs. We look at how and when to use the various JOIN commands.
The key topics trained include:
- Joining multiple tables in the FROM clause
- Different join types including INNER and OUTER joins and SELF joins
Session 3 - Single Row Functions
This session is an introduction to including mathematical calculations in your queries, for example how to multiply a quantity by a price, or how to calculate how old someone is. We also look at some of the useful date functions and how to use the functions to change the format of data.
The key topics include:
- Performing mathematical calculations
- The types of functions available in SQL
- Date functions including GetDate( ), DateADD( ), DateDIFF( )
- Conversion functions and their uses
- Column aliases
Session 4 – Aggregate Queries
SQL offers a number of ways to consolidate and aggregate the output of your queries. We begin by learning how to calculate the SUM, COUNT AVERAGE, MIN and MAX across the whole dataset and then look at how to write GROUP BY queries and limit these with the HAVING clause.
The key topics trained include:
- How to write aggregate queries
- COUNT vs Count(*)
- GROUP BY
Group Learning Events
If you have three or more learners, a private group course could be cheaper.
We can tailor the content to your team, and host the training remotely, at your workplace or here at Happy's HQ in Aldgate, Central London.
