| 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 |
| pushExpressions | | public void pushExpressions(PredicateList predicateList) throws StandardException(Code) | | Push expressions down to the first ResultSetNode which can do expression
evaluation and has the same referenced table map.
RESOLVE - This means only pushing down single table expressions to
DistinctNodes today. Once we have a better understanding of how
the optimizer will work, we can push down join clauses.
Parameters:
predicateList - The PredicateList.
exception:
StandardException - Thrown on error |
| 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 |

Parameters:
name - Table name (String) to search for.
Parameters:

exception:
StandardException - Thrown on error |

| updateTargetLockMode | | public int updateTargetLockMode()(Code) | | Get the lock mode for the target of an update statement
