The aim of this exercise is to use variables to present some information about yourself as a little sentence:

Variables can be fun

This could be your Tinder profile ...

Start by declaring the variables you will need:

To hold Use
Your name varchar(N)
Your birth date datetime
Your pet count int

The structure for a variable looks like this:

DECLARE @VariableName DataType

You can put data into variables using SET, SELECT or by setting them = to something. Using these three techniques put information about yourself into your variables:

DECLARE @Variable1 DataType = 'Your Name'

SET @Variable2 = 'Your dob'

SELECT @Variable3 = 'Your number of pets'

Try to make your variable names as relevant as you can to the information that they will contain.

Finally concatenate your variables with appropriate text to SELECT the sentence shown at the start of this exercise (you'll need to convert some of the data types to text to do this).

Optionally, save your query as Nice to meet you, then close it down.
