1062 - Duplicate entry 33 for key 1

Sometimes when we import data, something like 1062 - Duplicate entry '33' for key 1 will appear, right?

Then what is the reason for this? Yesterday I found such a problem when importing data.

After analysis, the reason is that the data ID I want to import already exists in the data table,

Now that you know the reason, the solution is up to you.
