Convert varchar to datetime

Hi,
I have what seems to be a simple issue, yet I can't get it to work:
I have a table that I have imported into SQL via a .txt file , one of the
fields holds a date (which was originally in the format of '122499'). I
added, based on certain criteria a '19' or '20' in front of the year to make
it '12241999' (still in a varchar type). But now when I try to insert it
into my final table which has a datatype as datetime, I'm having
difficulties, even if I try to convert or cast to datetime, I get the error
of:
Server: Msg 242, Level 16, State 3, Line 1
The conversion of a char data type to a datetime data type resulted in an
out-of-range datetime value.
I have read that if it is not in the default sql datetime format, this error
will appear, but I do seem to have it in the default order of mm/dd/yyyy.
Any suggestions?
Thank you in advance!Transpose the year to the beginning of the string. Instead of using CONVERT
just say:
RIGHT(col_name, 4) + LEFT(col_name, 4)
YYYYMMDD is the recommended format to guarantee. All these other format
(mmddyy, mmddyyyy, m/d/y, d/m/y, etc.) are completely and utterly for the
birds.

I tried what you suggested and it does transpose the date in my table, of
course, but I still get the same error when trying to insert that field into
my fact table which has a datetime datatype - do I still need to convert or
cast that field into datetime datatype?

No, but you should check if any of the data was bogus (my guess is there is
at least one) by SELECT COUNT(*) FROM OriginalTable WHERE ISDATE(Column) = 0
Just because you transpose 13131999 to 19991313 does not make it a valid
date. :-)
And thus, you see why date/time should always be stored as such, and never
as char.

given a local date:
-- use dateadd(hour, datediff(hour, GetDate(), GetUTCDate())
-- to get the current hour difference between UTC and local date
declare @.GetDateVal datetime
select @.GetDateVal = '20051117 15:00:00'
select @.GetDateVal, datediff(second, '19700101', dateadd(hour,
datediff(hour, GetDate(), GetUTCDate()), @.GetDateVal ) )
