Question

Ok this is how stupidly i am keeping my date as string

23.12.2012 21:24:31

Now at a select query i want to cast them as BigInt and do a search

casted version : "20121223212431"

like below

select * from myTable where cast(datestring as bigint) > 20111223212431 

How can i cast that kind of string to BigInt at sql server ?

Edit – why this query is not working

    select (convert(datetime,LastMoveTime,104)) as myTime from myTable
where myTime < DATEADD(day,-366,GETDATE())

error : Invalid column name ‘myTime’.

Answer 1

You should not do that, see John Skeet’s post, but

declare @dt datetime
select @dt='20121223 21:24:31'

Select Cast(Convert(Varchar(25),@dt,112)+Replace(Convert(Varchar(25),@dt,108),':','') as BigInt)
