在sql中将时间转换为仅hh：mm

Question

我目前正在处理以下查询，但我希望我的结果以hh:mm格式显示。我使用的是convert(char, mycolumnName, 108)，但我的结果仍显示为hh:mm:ss。我只需要hh:mm。有没有办法如何在hh:mm中获得此结果？请建议提前谢谢！

 select distinct 
     clientid, timein , timeout, calculation, 
     convert(char, calculation, 108) as CalculationResult 
 from 
     calculationTable 
 where 
     timein is not null and timeout is not null 

输出：

Clientid   timein     timeout    calculation           CalculationResult
------------------------------------------------------------------------    
0012345    09:00:00   05:00:00   1900-01-01 08:00:00   08:00:00

Answer 1

SELECT DISTINCT clientid,
    timein,
    timeout,
    calculation,
    convert(VARCHAR(5), calculation, 108) AS CalculationResult
FROM calculationTable
WHERE timein IS NOT NULL
AND timeout IS NOT NULL

试试这个

select 
  distinct clientid, 
  timein, 
  timeout, 
  calculation, 
  convert(varchar(5), calculation, 108) as CalculationResult
