Subject [jira] Created: (DERBY-4399) Syntax description for TableViewOrFunctionExpression lack subquery option

Syntax description for TableViewOrFunctionExpression lack subquery option
-------------------------------------------------------------------------

                 Key: DERBY-4399
                 URL: https://issues.apache.org/jira/browse/DERBY-4399
             Project: Derby
          Issue Type: Bug
          Components: Documentation
            Reporter: Dag H. Wanvik


In the reference manual, we find these syntax description (start with http://db.apache.org/derby/docs/dev/ref/rrefsqlj21583.html):

TableExpression:
{
  TableViewOrFunctionExpression | JOIN operation 
}

TableViewOrFunctionExpression:

{ table-Name | view-Name | TableFunctionInvocation}
    [ [ AS ] correlation-Name
        [ (Simple-column-Name [ , Simple-column-Name]* ) ] ] ]

I cannot find a way from the "FROM clause" to the TableSubquery production, so I think the
latter should read:

{ table-Name | TableSubquery | view-Name | TableFunctionInvocation }
    [ [ AS ] correlation-Name
        [ (Simple-column-Name [ , Simple-column-Name]* ) ] ] ]

Also, the "JOIN operation" is not clickable.
