> Yes, but it's an ID, not a value. In normalization theory and relational algebra an ID is just a value. DBMSs make no difference between this column and any other primary key column(s) and they make no difference between PK indexes over strings or numbers or any other supported data type. You're just cargo culting here instead of applying database theory or actually looking at implementations. |
