All known Subclasses: org.apache.derby.impl.sql.compile.SetOperatorNode, org.apache.derby.impl.sql.compile.JoinNode,
| TableOperatorNode | | abstract class TableOperatorNode extends FromTable (Code) | | A TableOperatorNode represents a relational operator like UNION, INTERSECT,
JOIN, etc. that takes two tables as parameters and returns a table. The
parameters it takes are represented as ResultSetNodes.
Currently, all known table operators are binary operators, so there are no
subclasses of this node type called "BinaryTableOperatorNode" and
"UnaryTableOperatorNode".

| Method Summary | |
| public Visitable | accept(Visitor v)
Accept a visitor, and call v.visit()
on child nodes as necessary. | | public void | bindExpressions(FromList fromListParam)
Bind the expressions under this TableOperatorNode. | | public void | bindExpressionsWithTables(FromList fromListParam)
Bind the expressions in this ResultSetNode if it has tables. | | public ResultSetNode | bindNonVTITables(DataDictionary dataDictionary, FromList fromListParam)
Bind the non VTI tables in this TableOperatorNode. | | public void | bindResultColumns(FromList fromListParam)
Bind the result columns of this ResultSetNode when there is no
base table to bind them to. | | public void | bindResultColumns(TableDescriptor targetTableDescriptor, FromVTI targetVTI, ResultColumnList targetColumnList, DMLStatementNode statement, FromList fromListParam)
Bind the result columns for this ResultSetNode to a base table.
This is useful for INSERT and UPDATE statements, where the
result columns get their types from the table being updated or
inserted into.
If a result column list is specified, then the verification that the
result column list does not contain any duplicates will be done when
binding them by name.
Parameters:
targetTableDescriptor - The TableDescriptor for the table beingupdated or inserted into
Parameters:
targetColumnList - For INSERT statements, the userdoes not have to supply columnnames (for example, "insert into tvalues (1,2,3)". | | public ResultSetNode | bindVTITables(FromList fromListParam)
Bind the VTI tables in this TableOperatorNode. | | void | decrementLevel(int decrement)
Decrement (query block) level (0-based) for
all of the tables in this ResultSet tree. | | public String | getExposedName()

the current query block.
Parameters:

"bound by hand" after the underlying left and right RCLs
are bound.
Parameters:
dataDictionary - The DataDictionary to use for binding

This is useful for INSERT and UPDATE statements, where the
result columns get their types from the table being updated or
inserted into.
If a result column list is specified, then the verification that the
result column list does not contain any duplicates will be done when
binding them by name.
Parameters:
targetTableDescriptor - The TableDescriptor for the table beingupdated or inserted into
Parameters:
targetColumnList - For INSERT statements, the userdoes not have to supply columnnames (for example, "insert into tvalues (1,2,3)". When thisparameter is null, it means thatthe user did not supply columnnames, and so the binding shouldbe done based on order. When itis not null, it means do the bindingby name, not position.

| needsSpecialRCLBinding | | public boolean needsSpecialRCLBinding()(Code) | | apparently something special needs to be done for me....
|
| preprocess | | public ResultSetNode preprocess(int numTables, GroupByList gbl, FromList fromList) throws StandardException(Code) | | Put a ProjectRestrictNode on top of each FromTable in the FromList.
ColumnReferences must continue to point to the same ResultColumn, so
that ResultColumn must percolate up to the new PRN. However,
that ResultColumn will point to a new expression, a VirtualColumnNode,
which points to the FromTable and the ResultColumn that is the source for
the ColumnReference.
(The new PRN will have the original of the ResultColumnList and
the ResultColumns from that list. The FromTable will get shallow copies
of the ResultColumnList and its ResultColumns. ResultColumn.expression
will remain at the FromTable, with the PRN getting a new
VirtualColumnNode for each ResultColumn.expression.)
We then project out the non-referenced columns. If there are no referenced
columns, then the PRN's ResultColumnList will consist of a single ResultColumn
whose expression is 1.
Parameters:
numTables - Number of tables in the DML Statement
Parameters:
gbl - The group by list, if any
Parameters:
fromList - The from list, if any The generated ProjectRestrictNode atop the original FromTable.
exception:
StandardException - Thrown on error |
| printSubNodes | | public void printSubNodes(int depth)(Code) | | Prints the sub-nodes of this object. See QueryTreeNode.java for
how tree printing is supposed to work.
Parameters:
depth - The depth of this node in the tree |
| projectResultColumns | | void projectResultColumns() throws StandardException(Code) | | Find the unreferenced result columns and project them out. This is used in pre-processing joins
that are not flattened into the where clause.
|
| referencesSessionSchema | | public boolean referencesSessionSchema() throws StandardException(Code) | | Return true if the node references SESSION schema tables (temporary or permanent)
true if references SESSION schema tables, else false
exception:
StandardException - Thrown on error |
| referencesTarget | | public boolean referencesTarget(String name, boolean baseTable) throws StandardException(Code) | | Search to see if a query references the specifed table name.
Parameters:
name - Table name (String) to search for.
Parameters:
baseTable - Whether or not name is for a base table true if found, else false
exception:
StandardException - Thrown on error |
| rejectParameters | | public void rejectParameters() throws StandardException(Code) | | Check for (and reject) ? parameters directly under the ResultColumns.
This is done for SELECT statements. For TableOperatorNodes, we
simply pass the check through to the left and right children.
exception:
StandardException - Thrown if a ? parameter founddirectly under a ResultColumn |
| setLevel | | public void setLevel(int level)(Code) | | Set the (query block) level (0-based) for this FromTable.
Parameters:
level - The query block level for this FromTable. |
| setNestedInParens | | public void setNestedInParens(boolean nestedInParens)(Code) | | Mark whether or not this node is nested in parens. (Useful to parser
since some trees get created left deep and others right deep.)
The resulting state of this cal was never used so its
field was removed to save runtimespace for this node.
Further cleanup can be done including parser changes
if this call is really nor required.
Parameters:
nestedInParens - Whether or not this node is nested in parens. |
| setReferencedColumns | | void setReferencedColumns()(Code) | | Set the referenced columns in the column list if it may not be correct.

See Also: Optimizable.updateBestPlanMap
See Also: Makes a call to add/load/remove the plan mapping for this node,
See Also: and then makes the necessary call to recurse on this node's
See Also: left and right child, in order to ensure that we've handled
