ISTM that correlation names aren't allowed after joined tables in the
first place.
        <table reference> ::=               <table name> [ [ AS ] <correlation name>                   [ <left paren>
<derivedcolumn list> <right paren> ] ]             | <derived table> [ AS ] <correlation name>                   [
<leftparen> <derived column list> <right paren> ]             | <joined table>
 
        <joined table> ::=               <cross join>             | <qualified join>             | <left paren> <joined
table><right paren>
