What is the difference between ‘console.log()’ and ‘printQueryResults()’?
Doesn’t ‘printQueryResults()’ print the results also?
If, how do they differ?
Yes, from what I tested, both provide the same result.
I do believe the main difference is that we can’t use printQueryResults() calls outside of Node-SQLite queries, while we can use console.log() everywhere using JavaScript.
I might be wrong though, so if anyone knows better, please let us know.
Because only the quantity column has been selected, why do I need to print row.quantity? Wouldn’t just row suffice?
db.get("SELECT quantity FROM SpiceRack WHERE name='paprika'", (err, row) => {
console.log(row);
})
db.get("SELECT quantity FROM SpiceRack WHERE name='paprika'", (err, row) => {
console.log(row.quantity);
});

I am confused about this too.
Looking at courses/learn-node-sqlite/lessons/learn-node-sqlite/exercises/retrieving-a-single-row…
using console.log(row) outputs an object(?): { temp_avg: 19.650000000000002 }
using console.log(row.temp_avg) outputs an intger: 19.650000000000002
(correct me if I’m wrong.)
