PHP

Error in Treehouse page?

Hi - I'm completing the SQL / PHP course and I'm stuck on the SELECT statement... or rather it's stuck?

I enter "SELECT 'price', 'name' FROM products" and the result says I've failed and shows this error...

f1705544-0c3f-4631-a4c4-d5185a161a1f.rb:37:in eval': undefined methodto_a' for # (NoMethodError) from f1705544-0c3f-4631-a4c4-d5185a161a1f.rb:37:in eval' from f1705544-0c3f-4631-a4c4-d5185a161a1f.rb:37:in'

SO... how do I complete the module?

Try removing the single quotes from the field names:

"SELECT price, name FROM products"

OK, that got it. Odd thing to have to do though, no?

Anyhoo - all is well, cheers Alex.

Because you wrapped the field names in quotes it is then treating the value as a string literal instead of an actual fields.

Say you had a WHERE clause and you wanted it to be equal to some value you would wrap it there:

"SELECT price, name FROM products WHERE name='apple' "

What a douche... work THEN beer next time. Cheers Alex!
