我想把原来一列datetime的数据类型转换成 一列date 和 一列 time(2),使用以下代码
SELECT top 1000 [id_stock]
,convert(date,date_trade) as date_trade1
,convert(time,date_trade) as time_trade1
但是在数据导入和导出工具里,date_trade1可以顺利转换,time_trade1 总是报源类型是 -1 无法转换。
但是我用这句sql 直接查表的话,可以两列都可以正常返回的,求助

- SQL code
SELECT top 1000 [id_stock],CONVERT(VARCHAR(10),date_trade,120) as date_trade1,CONVERT(VARCHAR(8),date_trade,108) as time_trade1

主要是日期格式问题:改成Select CONVERT(varchar(100), date_trade,24) 即可
