Question

当我从文本字段构建日期时，我收到错误。＆＃34;服务器：消息241，级别16，状态1，行1 从字符串转换datetime的语法错误。＆＃34; 我使用的文字就像＆＃34;航班提醒：尊敬的客户，2014年2月28日/ 28日航班延误，新ETD为0530小时/ 29Mar。＆＃34;

这是我的查询

    SELECT 
--- Extracting Flight No from Message field --
case
 when substring(oh_message,(charindex('/',OH_MESSAGE)-4),1) = '-' 
   or substring(oh_message,(charindex('/',OH_MESSAGE)-4),1) = 'K'
 THEN
   substring(oh_message,(charindex('/',OH_MESSAGE)-3),3)
 else
   substring(oh_message,(charindex('/',OH_MESSAGE)-4),4)
END AS flightno,

--- Converting to datetime format
CONVERT(datetime,

  + ' ' + 
 (substring(oh_message,(CHARINDEX('/',Oh_message)) + 1,2)) 
 + ' ' +
