I have this data.
"2mn 56s", "30s 83ms", "2h 10mn"
How to convert these into time format:
hh:mn:ss - "00:02:56", "00:00:30", "02:10:00"
In JavaScript, you can use String#replace
method.
var str = '"2mn 56s", "30s 83ms", "2h 10mn"'; console.log( str.replace(/"(?:(\\d)+h\\s*)?(?:(\\d+)mn\\s*)?(?:(\\d+)s\\s*)?[^"]*"?/g, function(_, m1, m2, m3) { return [m1, m2, m3].map(v => ('00' +( v || '')).slice(-2)).join(':') }) )
I wouldn't store TIME
in this format in the future. With that being said, based off your sample data here is a SQL Server solution. Uncomment out the @t1
variable to see different test cases.
declare @t1 varchar(16)
--set @t1 = '2h 10mn'
set @t1 = '2mn 56s'
--set @t1 = '30s 83ms'
--this places your data in a time format. This is ideal in most cases so you can actually use datetime functions on the data
select
case
when left(@t1, charindex(' ',@t1)) like '%h'
then convert(time,convert(varchar,left(@t1,charindex('h',@t1) - 1)) + ':' + substring(@t1,charindex(' ', @t1) + 1,len(@t1) - charindex(' ', @t1) - 2) + ':00')
end,
case
when left(@t1, charindex(' ',@t1)) like '%mn'
then convert(time,'00:' + convert(varchar,left(@t1,charindex('mn',@t1) - 1)) + ':' + substring(@t1,charindex(' ', @t1) + 1,len(@t1) - charindex(' ', @t1) - 1))
end,
case
when left(@t1, charindex(' ',@t1)) like '%s'
then convert(time,'00:00:' + convert(varchar,left(@t1,charindex('s',@t1) - 1)) + '.' + substring(@t1,charindex(' ', @t1) + 1,len(@t1) - charindex(' ', @t1) - 2))
end
--if you only want it in the hh:mm:ss then you can use the below. This rounds your milliseconds properly
select
case
when left(@t1, charindex(' ',@t1)) like '%h'
then convert(time(0),convert(varchar,left(@t1,charindex('h',@t1) - 1)) + ':' + substring(@t1,charindex(' ', @t1) + 1,len(@t1) - charindex(' ', @t1) - 2) + ':00')
end,
case
when left(@t1, charindex(' ',@t1)) like '%mn'
then convert(time(0),'00:' + convert(varchar,left(@t1,charindex('mn',@t1) - 1)) + ':' + substring(@t1,charindex(' ', @t1) + 1,len(@t1) - charindex(' ', @t1) - 1))
end,
case
when left(@t1, charindex(' ',@t1)) like '%s'
then convert(time(0),'00:00:' + convert(varchar,left(@t1,charindex('s',@t1) - 1)) + '.' + substring(@t1,charindex(' ', @t1) + 1,len(@t1) - charindex(' ', @t1) - 2))
