我正在寻找有关lua脚本的帮助，该脚本应该以可读的格式输出表的结果。
此脚本仅将结果打印为表引用：

database.open("provider=nis;database=nis;driver=none")

query = database.query("SELECT distinct cmcs.name, ms.schedule_name, mw.start_time, mw.end_time from MAINTENANCE_WINDOW mw INNER JOIN CM_DEVICE cmd on mw.dev_id = cmd.dev_id INNER JOIN CM_COMPUTER_SYSTEM cmcs on cmcs.cs_id = cmd.cs_id INNER JOIN MAINTENANCE_SCHEDULE ms on mw.schedule_id = ms.schedule_id where mw.end_time > GETDATE();")

print (query)

以上输出：

table:0x7fe8f40e6f00

我有以下脚本，但它没有输出我期望看到的内容：

database.open("provider=nis;database=nis;driver=none")

query = database.query("SELECT distinct cmcs.name, ms.schedule_name, mw.start_time, mw.end_time from MAINTENANCE_WINDOW mw INNER JOIN CM_DEVICE cmd on mw.dev_id = cmd.dev_id INNER JOIN CM_COMPUTER_SYSTEM cmcs on cmcs.cs_id = cmd.cs_id INNER JOIN MAINTENANCE_SCHEDULE ms on mw.schedule_id = ms.schedule_id where mw.end_time > GETDATE();")

if query == nil then
   print ("Query did not complete, or had no results")
else
   for idx,row in pairs (query) do
      printf("Hostname: %s \t IP: %s",row['name'],row['schedule_name'])
   end 
end

下面是在sql server本身上运行时sql输出的屏幕截图（如果有任何输出是这样的话）：
