在Apps脚本中运行多个SQL查询

Question

我有以下代码，

function report1() { 

  var conn = Jdbc.getConnection(url, name,passward);
  var sql =  conn.prepareStatement("SET @sql = NULL; ");
  var group_concat_max_len =  conn.prepareStatement("SET @@group_concat_max_len = 40000; ");
  var sel_querry =  conn.prepareStatement("SELECT GROUP_CONCAT(DISTINCT \
      CONCAT(' IFNULL(COUNT(case when pt.name =  ', '\'', name, '\'',' THEN 1 END),0) AS ', replace(name, ' ', '_')) \
      ) INTO @sql \
       from propertytypes; ");

  var set_querry = conn.prepareStatement(" SET @sql = CONCAT('SELECT c.name as city,date(pr.created_at) as date,' \
                     ,@sql, \
                  ', IFNULL(COUNT(pr.id),0) AS Total \
                  from properties pr \
                 LEFT JOIN cities c on c.id = pr.city_id \
                 LEFT JOIN propertytypes pt on pt.id = pr.propertytype_id where  pr.status = \'Active\' \
                 group by city, date(pr.created_at) \
                 ORDER BY date,Total DESC');");


  var stmt = conn.prepareStatement(" PREPARE stmt FROM @sql; ");
  var execute = conn.prepareStatement(" EXECUTE stmt; ");
  var deallocate =conn.prepareStatement( " DEALLOCATE PREPARE stmt; ");

   sql.executeQuery(); 
   group_concat_max_len.executeQuery();
   sel_querry.executeQuery();
   set_querry.executeQuery();
   stmt.executeQuery();  
   execute.executeQuery();
   deallocate.executeQuery();


   var mat1 = [];
   mat1[0] = [];

  for (j=0; j<result1.getMetaData().getColumnCount(); j++){
  mat1[0].push(result1.getMetaData().getColumnName(j+1));
 }

  var row = 0;  
  while(result1.next()) {
   mat1[row+1] = [];

   for(var i=0; i<1; i++) {     // four fields per record
      mat1[row+1][i] = result1.getString(i+1);
    }
    for(var i=1; i<result1.getMetaData().getColumnCount(); i++) {     // four fields per record
      mat1[row+1][i] = result1.getInt(i+1);
    }
    row++;
 }

  return mat1;

 }

但是我得到一个错误：“你的SQL语法有错误;请查看与你的MySQL服务器版本相对应的手册，以获得正确的语法，使用靠近''group by city，date（pr.created_at）ORDER BY '在第1行（第74行，文件“asd”）“。在set_querry.executeQuery();

但是mysql代码在workbench中工作。任何人都可以找出问题。？
