I am using "substring(concat('00'...." within my SQL select for a date query. However, the date 10 and higher is being overridden with "0". How do I prevent this from happening?

Please show the entire SQL statement. It is impossible to know what you are doing by looking at the fragment. Table definition info would also help.

KCCrosser – If you are trying to ensure the month and day are 2-digits with leading zeros, the easy way is to use:

set @monthstring = right(’0′ + convert(varchar(2),month(<date>)),2)
set @daystring = right(’0′ + convert(varchar(2),day(<date>)),2)

I.e. prepend a ’0′ character on the current string, then take the rightmost two characters. For values like ’10′, this creates ’010′, then take the rightmost 2 to get ’10′. For digits 1-9, it returns ’01′ thru ’09′.
