WL#928: Disallow duplicate names in some column lists
Affects: Server-7.1 — Status: Un-Assigned
It should be an error to use the same column name twice in column lists where the column cannot actually appear twice. Example: CREATE TABLE t (s1 INT, PRIMARY KEY (s1,s1)) /* the above is illegal */ SELECT * FROM x AS y (s1,s1) /* the aboe is illegal */
