Instruction
Great! Now, what happens if we don't know precisely what letters we're looking for? With text values, you can always use the LIKE operator instead of the equality sign. What change does it make? Well, take a look at the following example:
SELECT * FROM user WHERE name LIKE 'A%';
LIKE allows for the use of the percentage sign (%). The percentage sign applied in the example matches any number (zero or more) of unknown characters.
As a result, we'll obtain all users whose name begins with the letter 'A'. We may not remember someone's exact name, but we know it begins with an A and that's enough. Convenient, isn't it?
Exercise
Select vin, brand, and model of all cars whose brand begins with an F.
Stuck? Here's a hint!
Type:
SELECT vin, brand, model FROM car WHERE brand LIKE 'F%';
