It looks like you are confused about when to use integer values and varchar values.

An integer will contain the number. The normal presentation of the number doesn't include leading zeros. Setting @MaxValue = '0001' will give @MaxValue the value of 1. The leading zeros are irrelevant for integers.

If you wish to display an integer with leading zeros, then it needs to be converted to a string somewhere. Normally, this would be done in the UI presentation (ie the web page) rather than the database.

If you wish to store the data with the leading zeros in the database, then the datatypes need to be varchar rather than integer.
