MySQL Select: WHERE (time now) = BETWEEN tablevalue AND tablevalue

Question

I'm looking for a way to select the row in which the current time is between two set values in the row. I've set up a table with 3 columns, 2 of them hold a timestamp (HH:MM:SS), the other one a string. Is there a way I can get the string corresponding to the current time? To put it in a more abstract way:

SELECT String FROM TableName WHERE (Current Time) BETWEEN (Lower Limit Time Value) AND (Upper Limit Time Value);

So basically, based on the current time, my script should output the correct string.

How do I go about this? Thanks!

Answer 1

In MySQL, timestamp is quite a confusing word.

If they are lowerlimit and upperlimit are TIME columns from 00:00:00 to 23:59:59:

SELECT  String
FROM    TableName
WHERE   CURTIME() BETWEEN lowerlimit AND upperlimit
        OR CURTIME() BETWEEN SUBTIME(upperlimit, '24:00:00') AND lowerlimit
        OR SUBTIME(CURTIME(), '24:00:00') BETWEEN SUBTIME(upperlimit, '24:00:00') AND lowerlimit

This will handle midnight transitions correctly.

Answer 2

SELECT string_col
FROM your_table
WHERE CURTIME() BETWEEN lower_limit_col AND upper_limit_col
