Field Detail tableConstructor boolean tableConstructor(Code) topTableConstructor boolean topTableConstructor(Code) Method Detail bindExpressions public void bindExpressions(FromList fromListParam) throws StandardException(Code) Bind the expressions under this TableOperatorNode. This means binding the sub-expressions, as well as figuring out what the return type is for each expression. exception:   StandardException - Thrown on error generate public void generate(ActivationClassBuilder acb, MethodBuilder mb) throws StandardException(Code) Generate the code for this UnionNode. exception:   StandardException - Thrown on error getFinalCostEstimate public CostEstimate getFinalCostEstimate() throws StandardException(Code) See Also:   ResultSetNode.getFinalCostEstimate See Also:   Get the final CostEstimate for this UnionNode. The final CostEstimate for this UnionNode, which isthe sum of the two child costs. getOperatorName String getOperatorName()(Code) init public void init(Object leftResult, Object rightResult, Object all, Object tableConstructor, Object tableProperties) throws StandardException(Code) Initializer for a UnionNode. Parameters:   leftResult - The ResultSetNode on the left side of this union Parameters:   rightResult - The ResultSetNode on the right side of this union Parameters:   all - Whether or not this is a UNION ALL. Parameters:   tableConstructor - Whether or not this is from a table constructor. Parameters:   tableProperties - Properties list associated with the table exception:   StandardException - Thrown on error markTopTableConstructor public void markTopTableConstructor()(Code) Mark this as the top node of a table constructor. modifyAccessPath public Optimizable modifyAccessPath(JBitSet outerTables) throws StandardException(Code) See Also:   Optimizable.modifyAccessPath exception:   StandardException - Thrown on error modifyAccessPaths public ResultSetNode modifyAccessPaths() throws StandardException(Code) See Also:   ResultSetNode.modifyAccessPaths exception:   StandardException - Thrown on error optimizeIt public CostEstimate optimizeIt(Optimizer optimizer, OptimizablePredicateList predList, CostEstimate outerCost, RowOrdering rowOrdering) throws StandardException(Code) See Also:   org.apache.derby.iapi.sql.compile.Optimizable.optimizeIt exception:   StandardException - Thrown on error pushExpressions public void pushExpressions(PredicateList predicateList) throws StandardException(Code) DERBY-649: Handle pushing predicates into UnionNodes. It is possible to push single table predicates that are binaryOperations or inListOperations. Predicates of the form or IN are currently handled. Since these predicates would allow optimizer to pick available indices, pushing them provides maximum benifit. It should be possible to expand this logic to cover more cases. Even pushing expressions (like a+b = 10) into SELECTs would improve performance, even if they don't allow use of index. It would mean evaluating expressions closer to data and hence could avoid sorting or other overheads that UNION may require. Note that the predicates are not removed after pushing. This is to ensure if pushing is not possible or only partially feasible. Parameters:   predicateList - List of single table predicates to push 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. Don't reject parameters that are in a table constructor - these are allowed, as long as the table constructor is in an INSERT statement or each column of the table constructor has at least one non-? column. The latter case is checked below, in bindExpressions(). exception:   StandardException - Thrown if a ? parameter founddirectly under a ResultColumn setTableConstructorTypes void setTableConstructorTypes(ResultColumnList typeColumns) throws StandardException(Code) Set the type of column in the result column lists of each source of this union tree to the type in the given result column list (which represents the result columns for an insert). This is only for table constructors that appear in insert statements. Parameters:   typeColumns - The ResultColumnList containing the desired resulttypes. exception:   StandardException - Thrown on error tableConstructor boolean tableConstructor()(Code) Tell whether this is a UNION for a table constructor. toString public String toString()(Code) Convert this object to a String.
