提问by user517406

I am trying to convert a date into this format YYYY-MM-DD hh:mm:ss eg. 2007-01-05 23:00:00. But my SQL leaves the string unchanged, can somebody tell me what I am doing wrong?

Try SELECT CONVERT(DATETIME, '23/02/2008 00:00:00'). All you're doing is converting a string into a string, which won't change anything.

试试SELECT CONVERT(DATETIME, '23/02/2008 00:00:00')。您所做的只是将字符串转换为字符串,这不会改变任何内容。
