推荐答案

如果要返回行，则只需执行以下操作:

If you want to return the rows then just do this:

  local function getListFromDatabase()
     local select_stmt = db:prepare("SELECT * FROM list")
     return select_stmt:rows()
  end

然后您可以像这样使用它:

then you can use it like this:

  local rows = getListFromDatabase()

我请您参考用户手册: http://www.lua.org/manual/5.1/manual.html
