Summary

Instruction

Nice. Did you try to insert a value like 1.236? Did you see what happened? It was rounded to 1.24. This is because we specified two digits after the decimal point when creating the column. Once you provide the precision and scale, you can't exceed it.

Exercise

Let's check how much tax Peter is going to pay. Select 0.15 of every amount from the payment table. Name this column tax.

Stuck? Here's a hint!

Type:

SELECT 0.15 * amount AS tax
FROM payment;
