DATEDIFF可以在几小时内获得差异

Question

I have two columns that have time data that looks like "2017-12-06 18:50:27 +0000" . What MySQL function can I use to get the difference in hours of the two date time strings? I tried DATEDIFF(time_string_1, time_string_2) but it isn't working. What else can I use?

Answer 1

You can use the timestampdiff function:

SELECT TIMESTAMPDIFF(HOUR, col1, col2)
FROM   mytable

Answer 2

Use TIMESTAMPDIFF function.

Syntex:

TIMESTAMPDIFF(unit,datetime_expr1,datetime_expr2)

Where Unit is:

Microseconds, Seconds, Minutes, Hours, Days, Weeks, Months, Quarters, Years.

Query:

select TIMESTAMPDIFF(HOUR, time_string_1, time_string_2) 
from table_name
