I do not understand the concept of WHERE (column, operator and value is put)

During challenge 1 of 3 I did not understand where I was going wrong, can you explain what the end result would have been

A "WHERE" clause generally contains a comparison expression that limits which rows will be included in the output.

In this case, the instructions say where the username is equal to "wig_lady", so the clause added on to the end of the SELECT would look like: "WHERE username = 'wig_lady'".

For more specific answers, always show your complete query with your question.

select first_name,last_name from users where username = 'wig_lady'. Let me break it down for you. SQL Queries are based on a simple idea like.

Select { What you are looking for in a table ,(I believe you already know that) }
From { From which table you expect to receive the data }
Where { All the conditions that will distinguish the desired result }
          -- In this case you want first and last name of a person who has username as 'wig_lady'
