How to convert an int column ,Birthdate( sample value 20090301) to a date column in the format(01/03/2009) Sql Server 2000

I was trying to convert some thing like below

where 
cast(dob as datetime)>='01/03/2009'
which gives an error

Msg 8115, Level 16, State 2, Line 1
Arithmetic overflow error converting expression to data type datetime.
Solution

  • SQL Server doesn't allow you to cast int -> datetime directly, but if you're sure you can cast it to nvarchar first and then cast it to date. For your question here's an example

    declare @test int = 20090301
select CONVERT(datetime, CAST(@test as nvarchar), 112)

    112 is the format you mentioned, here's the list of all possible formats for Convert function.
