2,201 PointsUsing wildcards: putting it at the end vs enclosing the phrase with wildcards
-- Find all Playstation 4 products. Try and do this with 3 different queries.
I used the query below. The presenter puts the wildcard only at the end. Is there a particular reason why he would put it at the end like "Playstation 4%" rather than at each of the two sides to find all Playstation 4 products?
SELECT * FROM products WHERE name LIKE "%Playstation 4%";

Treehouse TeacherHi there, Ra Bha! It's probably because adding the wildcard to both sides might get you more results than you're counting on. For instance, if there were a product named "Happy Toddler Playdough Playstation 40", that would also match. Having the wildcard on either side says "if this is found anywhere in that string, include it in the results". So the above would also match, even though it's clearly not the gaming console we had in mind
Hope this helps!
