Question

Hi is there any simple way to convert hours to seconds? by using sql query.

Ex: @mytime = 2:15 hours

expected output is @result = 8100 seconds.

2 * 3600 + 15 * 60 = 8100

Thanks

You already presented the simplest way 😎

If you want to convert hour string, then:

DECLARE @str VARCHAR(10) = '5:35'

SELECT 
    CAST(SUBSTRING(@str, 1, CHARINDEX(':', @str, 1)-1) AS INT)*3600+
    CAST(SUBSTRING(@str, CHARINDEX(':', @str, 1)+1, 1000) AS INT)*60
