Entering a number string with 0 in front in MySQL DB

This exact problem seems to have been asked before!

The solution I linked to above assumes your zip code column is an integer type. Alternatively, you can change the column to be a varchar - there's an example of this too:

Let me know if you have any issues

My table has 2 columns, one called school_id and one called zip. If I do the ZEROFILL will it add a zero to both fields? I would just like the 0 added to the zip codes on the zip column that did not import the beginning 0 (sometimes 2 beginning zeros).

The zerofill option just applies to an individual column, however it will apply to all rows in the table, up to the number of characters indicated by the column length eg int(5) would add zeroes to make it up to 5 characters. Will this meet your requirements?

How would I indicate which column I wanted this applied to if the table name was zip_achool and the column was zip?

Thanks

Thanks so much for the prompt reply!
