Generally I choose int or tinyint for that but if I choose varchar it will be more clear while seeing data directly from the database table or while querying it.
But would it be the good practice to use varchar?
Or what is the good practice?
Thanks!
For indexing reasons a small numeric column would be better to use than a varchar, the size of which can only be determined by how many values are in the enumeration. If you require the text value to be returned from the database, store the text values in a separate lookup table and join when required.
