Unlike most sequel's SQL is necessary.

SO WHAT IS IT ?

SQL is a language. A very strict language.

When you speak SQL you must be very specific and exact.

In everyday native speaking conversations there are a lot of linguistical gaps that are filled in but that is a function that does not carry over to SQL.

SQL is a written language. That follows a certain structure just like most languages.

For Example, the structure for an independent clause in the English language contains a subject and a verb. I.e. " I love Pizza ".

In SQL the basic format is

Select - "  Who ? aka the Subject(s) [Column(s) ] "

From - " The location where the subject(s) is/are"

Where - " kind of like a verb - or a condition ( Where this condition exist this column   "

These two formats are different but after spending some time with SQL I have learned the ultimate way to become incredibly fluent in it.

Practice.

Like you would with any other language.

languages are skills to communicate. SQL is a language to communicate with data bases. The more fluent you become at communicating what you want the easier it would be to generate the actions you want.

I wonder if I can get SQL on DuoLingo.
