| bindParameters | | final void bindParameters(FromList fromList, SubqueryList subqueryList, Vector aggregateVector) throws StandardException(Code) | | Bind this expression. This means binding the sub-expressions,
as well as figuring out what the return type is for this expression.
Parameters:
fromList - The FROM list for the query thisexpression is in, for binding columns.
Parameters:
subqueryList - The subquery list being built as we find SubqueryNodes
Parameters:
aggregateVector - The aggregate vector being built as we find AggregateNodes
exception:
StandardException - Thrown on error |
| categorize | | public boolean categorize(JBitSet referencedTabs, boolean simplePredsOnly) throws StandardException(Code) | | Categorize this predicate. Initially, this means
building a bit map of the referenced tables for each predicate.
If the source of this ColumnReference (at the next underlying level)
is not a ColumnReference or a VirtualColumnNode then this predicate
will not be pushed down.
For example, in:
select * from (select 1 from s) a (x) where x = 1
we will not push down x = 1.
NOTE: It would be easy to handle the case of a constant, but if the
inner SELECT returns an arbitrary expression, then we would have to copy
that tree into the pushed predicate, and that tree could contain
subqueries and method calls.
RESOLVE - revisit this issue once we have views.
Parameters:
referencedTabs - JBitSet with bit map of referenced FromTables
Parameters:
simplePredsOnly - Whether or not to consider methodcalls, field references and conditional nodeswhen building bit map boolean Whether or not source.expression is a ColumnReferenceor a VirtualColumnNode.
