使用mysql.js执行UPDATE语句

Question

Im using mysqljs and I'm trying to UPDATE a table but it shows me an error with my SQL sentence.

the documentation states that

connection.query('UPDATE users SET foo = ?, bar = ?, baz = ? WHERE id = ?', ['a', 'b', 'c', userId], function(err, results) {
  // ...
});

But when I try to do it, the query creates all the variables that I'm sending to the first ?, ignorign the other ones, like this

values = [1,2,3,4,5]
sql = 'UPDATE tablename SET col1= ?, col2 = ?, col3= ?, col4 = ? WHERE col5=  ?';

  var query = connection.query(sql, [values], function(err) {
      if (err) {
        console.log(err);
        throw err;
      }
      else {
        connection.end();
      }
  })

But the query that gets executes is:

UPDATE tablename SET col1= 1, 2, 3, 4, col2 = ?, col3= ?, col4 = ? WHERE col5=  ?';

I don't know what I'm doing wrong or what to do to fix it.

Answer 1

You aren't passing an array of values, you are passing an array of an array of values. Stop doing that.
