B.4. The FROM Clause
The FROM clause contains a list of
TableReference's.
NamedTable- represents a single TableJoin- has a left and rightTableReferenceand information on the join between the itemsDerivedTable- represents a table defined by an inlineQueryExpression
A list of
TableReference are used by default, in the pushdown query when no outer joins are used. If an outer join is used anywhere in the join tree, there will be a tree of Joins with a single root. This latter form is the ANSI perfered style. If you wish all pushdown queries containing joins to be in ANSI style have the capability "useAnsiJoin" return true. Refer to the section on command form for more information.
