Table name specified more than once

Hello,

I am having troubles with the following query

UPDATE "public"."Workstations" SET "Last_Access" = "c1"."Last_Access",
"First_Access" = "c1"."First_Access", "Hits" = "C1"."Hits" FROM
"public"."Workstations" INNER JOIN (select min("Access_Time") as
"First_Access", max("Access_Time") as "Last_Access", count(*) AS "Hits",
"Workstation_Id" FROM "public"."Connections" GROUP BY "Workstation_Id") C1
on "public"."Workstations"."Workstation_Id" = "c1"."Workstation_Id"

It results in a "Table name "Workstations" specified more than once" error
message. Can anyone help me with correcting the syntax?

Thank you,
Alexander
