Question

在google apps脚本中，有一种方法可以使用mysql表中的数据填充列表项。我编写了我的函数但是在下拉列表中未定义。你能指点我做错了吗？

    function readFormListFromTable() {
var address = 'database_IP_address';
var user = 'user_name';
var userPwd = 'user_password';
var db = 'database_name';
var dbUrl = 'jdbc:mysql://' + address + '/' + db;
  var conn = Jdbc.getConnection(dbUrl, user, userPwd);
  var stmt = conn.createStatement();
  var results = stmt.executeQuery('SELECT [name] FROM employee');
  var numCols = results.getMetaData().getColumnCount();
  while (results.next()) {
    var rowString = '';
    for (var col = 0; col < numCols; col++) {
      rowString += results.getString(col + 1) + '\t';
    }
  }
  results.close();
  stmt.close();
var form = FormApp.openById('42udfksdfksukdnf-DWER');
var tablelistitem = form.addListItem();        
tablelistitem.setTitle('Name from mysql table')
                   .setChoices([tablelistitem.createChoice(rowString)]);   
}

我们将下一个脚本开发为Form并在open上配置tigger，以填充下拉列表及其工作。我希望这段代码可以帮助你：

function onOpen(){
var conexion=conectar_mysql(); //realizo conexion con mysql
var tiposHora=getTiposHora(conexion); //genero una lista con los tipos de hora disponibles
var form = FormApp.openById('form_id');
var item = form.addListItem(); // lista de todos los elementos que pertenecen al formulario para recargar el que me interese
item.setTitle('Tipos de Horas')
item.setChoiceValues(tiposHora);//recarga con los valores que necesito

}

function getTiposHora(conexion){
 var stmt = conexion.createStatement();
 var results = stmt.executeQuery('SELECT tipo FROM bbdd.tabla;');
 var numCols = results.getMetaData().getColumnCount();
 var tiposDeHora=[];
 while (results.next()) {
     var rowString = '';
     for (var col = 0; col < numCols; col++) {
          rowString += results.getString(col + 1) + '\t';
          tiposDeHora.push(rowString);
     }
 }
 return tiposDeHora;

}

function conectar_mysql(){

 var address = 'direccion';
 var user = 'usuario';
 var userPwd = 'password';
 var db = 'bbdd';
 var instanceUrl = 'jdbc:mysql://' + address;
 var dbUrl = instanceUrl + '/' + db;
 var conn = Jdbc.getConnection(dbUrl, user, userPwd);
 conn.setAutoCommit(false);
 return conn;

}
