The meaning of gray dots located at the table fields?

Can you tell me what is symbolized by the gray dots located next to the logotype of the field?

enter image description here

For example ID or PK_Players field.. :)

Solution

  • The gray circle means the column is not nullable.

    Additionally, blue indicates an indexed column and gray indicates a non-indexed column, so in your picture, Name would not be indexed, and id is indexed, but it's a key so it gets its own key icon instead of a blue column icon.
