| bindConstraints | | public ValueNode bindConstraints(DataDictionary dataDictionary, NodeFactory nodeFactory, TableDescriptor targetTableDescriptor, Dependent dependent, ResultColumnList sourceRCL, int[] changedColumnIds, FormatableBitSet readColsBitSet, boolean skipCheckConstraints, boolean includeTriggers) throws StandardException(Code) | | Gets and binds all the constraints for an INSERT/UPDATE/DELETE.
First finds the constraints that are relevant to this node.
This is done by calling getAllRelevantConstriants(). If
getAllRelevantConstraints() has already been called, then
this list is used. Then it creates appropriate
dependencies. Then binds check constraints. It also
generates the array of FKInfo items that are used in
code generation.
Note: we have a new flag here to see if defer processing is enabled or
not, the only scenario that is disabled is when we reapply the
reply message we get from the source
Parameters:
dataDictionary - The DataDictionary
Parameters:
nodeFactory - Where to get query tree nodes.
Parameters:
targetTableDescriptor - The TableDescriptor
Parameters:
dependent - Parent object that will depend on all the constraintsthat we look up. If this argument is null, then weuse the default dependent (the statement being compiled).
Parameters:
sourceRCL - RCL of the table being changed
Parameters:
changedColumnIds - If null, all columns being changed, otherwise arrayof 1-based column ids for columns being changed
Parameters:
readColsBitSet - bit set for the read scan
Parameters:
skipCheckConstraints - whether to skip check constraints or not
Parameters:
includeTriggers - whether triggers are included in the processing The bound, ANDed check constraints as a query tree.
exception:
StandardException - Thrown on failure |

exception:

Parameters:
readColsBitSet - A language style (1 based) bit set with bits forread heap columns set.RESOLVE: Replace this with a call to RowUtil when the store andthe language both use 0 base or 1 base offsets for columns. Todaywe can't use the store function because we have a 1 based FormatableBitSet. |

| optimize | | public QueryTreeNode optimize() throws StandardException(Code) | | Generate an optimized QueryTree from a bound QueryTree. Actually,
it can annotate the tree in place rather than generate a new tree,
but this interface allows the root node of the optimized QueryTree

Throws an exception if the tree is not bound, or if the binding
is out of date.
