How do you get an outside key?

Well, there are two tables in the OBD system. MySQL
First:
id | name | lastname | surname | id_key |
Second:
id_key | car | city|
id_key without A.I. the code consists of six figures.
I need the user to inject the code.id_keyin its table, as would be the case with the other table. What do you want? To create id_key external key, how?

INSERT INTO `table2` (`id_key`) SELECT `id_key` FROM `table1` ORDER BY `id` DESC LIMIT 0,1

Right? On condition id AUTO_INCREMENT♪

For example, https://docs.python.org/3/library/os.html#os.startfile ♪ This method works as if the file was triggered by a double click, the programmes will be launched, and the associated software will be created for the files.Example:import os os.startfile('firefox') os.startfile('C:/firefox.exe') os.startfile('C:/img.jpg')

Just failed to use String.fromCharCode() to get the key pressed (rather than the number).var pressed = document.getElementById('pressed'); function keyPressed(evt){ evt = evt || window.event; var key = evt.keyCode || evt.which; return String.fromCharCode(key); } document.onkeypress = function(evt) { var str = keyPressed(evt); pressed.innerHTML += str; };<h2 id='pressed'>Teclas pressionadas: </h2>Example requested in comments:function keyPressed(evt){ evt = evt || window.event; var key = evt.keyCode || evt.which; return String.fromCharCode(key); } document.onkeypress = function(evt) { var str = keyPressed(evt); if(str == 'f') alert("Apertou o 'f', chamando uma função..."); };<p>Pressione a tecla F</p>

But the program is making a mistake.Because... max determines the maximum of the collection elements, such as the lists. You've got it. age There will be a number.Explain the algorithm:For а) and б) The point is, we group the key data, then we analyze the keys and draw the results. It's convenient to use a vocabulary where the list will be relevant, so there may be a few results. ♪ а) The key will be age, and for б) - length of nameFor в) You just need to count the amount of age and split it by number. For ease of keeping them on the list, but there are two variables: the sum and the quantityExample:from collections import defaultdict persons = [ {"name": "Sam", "age": 10}, {"name": "Jackky", "age": 41}, {"name": "Mal", "age": 12}, {"name": "Ray", "age": 97} ] age_by_names = defaultdict(list) len_name_by_names = defaultdict(list) ages = [] for p in persons: name = p['name'] age = p['age'] age_by_names[age].append(name) len_name_by_names[len(name)].append(name) ages.append(age) min_age = min(age_by_names) print('min_age:', *age_by_names[min_age]) max_len_name = max(len_name_by_names) print('max_len_name:', *len_name_by_names[max_len_name]) print('average:', sum(ages) // len(ages))

how to get value from the variable that lies outside the functionReferral to the variable described in the functionThe answer to the first question is simple - global variables are available inside the function, so simply by name.var myVar = ''; function show(st) { myVar += st; } show('бла-бла'); console.log(myVar); You can't go on second! I advise you on the visibility of variables - http://habrahabr.ru/post/78991/ ♪ http://habrahabr.ru/post/127482/ ♪ http://vvz.nw.ru/Lessons/JavaScript/scope.htm and http://javascript.ru/basic/functions ♪ Why?Because the local variable is that it ceases to exist after leaving the function. Ground solution - global variable (see above).PSI suggest you read as described. http://javascript.ru/basic/functions and http://learn.javascript.ru/variables JavaScript. ♪ ♪And I advise you to read it. http://javascript.ru ♪PS2You can't describe it twice, that is, var should be used for the variable once... ♪And the moment, I care about the deep meaning of your function.var s = function show(st) { var a = ''; var a += st; } What did you expect from that tape?Did you even try to check it at the browser? You ever look at the console?

There you go.n = input() if n in shelf and not shelf[n]: del shelf[n] n in shelf - Let's check that the key is in the dictionary.not shelf[n] Let's check that the key is an empty list.del shelf[n] - remove a pair of keys/ keys

What do you mean, no cycles? Without use for? If so, it's like this:result = array.map(x => x.same_field) And if you mean no cycles at all, you can go the list, but you're wondering what purpose?

To work with more than one value within a JComboBox I recommend you do a class that contains the kind of Objeto which you want to access after the selection.public class Objeto { private String nombre; private String codigo; public Objeto (String nombre, String codigo) { this.nombre = nombre; this.codigo = codigo; } public String getNombre() { return nombre; } public String getCodigo() { return codigo; } @Override public String toString(){ return nombre; } } Then when you want to add an object to your ComboBoxcomboBox.addItem(new Objeto (rs.getString(1), rs.getString(2))); And finally when you want to get the values of what I select in you comboBoxEDITLike you comboBox It's the guy. Object when the user selects an item, you can get getSelectedItem() and save it in a variable of the type Object, so you can access their properties.Objeto object = comboBox.getSelectedItem(); String codigo = ((Objeto)object).getCodigo(); String nombre = ((Objeto)object).getNombre(); EDIT 2To check whether or not there is a selected item in your comboBox :if (comboBox.getSelectedItem() == null) { //Error } EDIT 3As you want to have a "reference" value in your comboBox For example "Select", I advise you to add it also as an object.comboBox.addItem(new Objeto ("Seleccione....", "0")); And to evaluate if this was selected (so should not serve and send an alert to the user) simply checkObjeto object = comboBox.getSelectedItem(); String codigo = ((Objeto)object).getCodigo(); String nombre = ((Objeto)object).getNombre(); if(codigo.equeals("0")){ //error }

I recommend using a checkup of the result mysqli_query to know what's going on. Besides checking $sql in the if you will never give you false, since it is simply a string, in this case it is preferable to check the result of mysqli_query (guarded in $res)$res= mysqli_query($con, $sql) or die(mysqli_error($con)); if ($res) { echo "Pelicula agregada!"; }

Probably V:sudo apt-get purge mysql* -V Shows the version of the removed package. So, you're removing mysql and-V is helping to find out which package will be removed. -V, --verbose-versions Show full versions for upgraded and installed packages.

He doesn't need to be generated at all.It's a public key that Docker's packages are signed so the users can be sure the package came from Docker's team. The launch team described there. apt-key (long with a large block of alphabetical at the end) fully implements the appendix procedure and contains additives (the most bundle of alphabetical digits) to make sure it's the key that was meant on the website.Can we believe the team set out in this instruction and think it's the right key? Well, if you're looking at the HTTPS page and don't get any warnings about the wrong certificate, then yes. Assuming, of course, you didn't add anything to your original certificates. You or someone like your system manager.

What you want to do is a JOIN between tables linking them through the user field.users and dependent contracts.zv. Unless you want a specific user the way to get the list would be using the following query "select * from contratospendientes join usuarios on usuarios.usuario = contratospendientes.zv" The condition where it is not necessary, unless you want a specific user then you could put where users.users = 'specific user'
