Description

Interface Summary

AggregatingScope	An extension to the SqlValidatorScope interface which indicates that the scope is aggregating.
SqlMoniker	An interface of an object identifier that represents a SqlIdentifier
SqlValidator	Validates the parse tree of a SQL statement, and provides semantic information about the parse tree.
SqlValidatorCatalogReader	Supplies catalog information for SqlValidator.
SqlValidatorNamespace	A namespace describes the relation returned by a section of a SQL query.
SqlValidatorScope	Name-resolution scope.
SqlValidatorTable	Supplies a SqlValidator with the metadata for a table.
SqlValidatorWithHints	Extends SqlValidator to allow discovery of useful data such as fully qualified names of sql objects, alternative valid sql objects that can be used in the SQL statement (dubbed as hints)

Class Summary

AbstractNamespace	Abstract implementation of SqlValidatorNamespace.
AggChecker	Visitor which throws an exception if any component of the expression is not a group expression.
AggFinder	Visitor which looks for an aggregate function inside a tree of SqlNode objects.
AggregatingSelectScope	Scope for resolving identifers within a SELECT statement which has a GROUP BY clause.
AliasNamespace	Namespace for an AS t(c1, c2, ...) clause.
CollectNamespace	Namespace for COLLECT and TABLE constructs.
CollectScope	The name-resolution context for expression inside a multiset call.
DelegatingNamespace	An implementation of SqlValidatorNamespace that delegates all methods to an underlying object.
DelegatingScope	A scope which delegates all requests to its parent scope.
DelegatingSqlValidatorCatalogReader	Implementation of SqlValidatorCatalogReader that passes all calls to a parent catalog reader.
DelegatingSqlValidatorTable	Implements SqlValidatorTable by delegating to a parent table.
EmptyScope	Deviant implementation of SqlValidatorScope for the top of the scope stack.
FieldNamespace	Implementation of SqlValidatorNamespace for a field of a record.
IdentifierNamespace	Namespace whose contents are defined by the type of an identifier.
JoinNamespace	Namespace representing the row type produced by joining two relations.
JoinScope	The name-resolution context for expression inside a JOIN clause.
ListScope	Abstract base for a scope which is defined by a list of child namespaces and which inherits from a parent scope.
OrderByScope	Represents the name-resolution context for expressions in an ORDER BY clause.
OverScope	The name-resolution scope of a OVER clause.
ParameterNamespace	Namespace representing the type of a dynamic parameter.
ParameterScope	A scope which contains nothing besides a few parameters.
ProcedureNamespace	Namespace whose contents are defined by the result of a call to a user-defined procedure.
SelectNamespace	Namespace offered by a subquery.
SelectScope	The name-resolution scope of a SELECT clause.
SetopNamespace	Namespace based upon a set operation (UNION, INTERSECT, EXCEPT).
SqlIdentifierMoniker	An implementation of SqlMoniker that encapsulates the normalized name information of a SqlIdentifier.
SqlMonikerComparator	A general-purpose implementation of Comparator to compare SqlMoniker values.
SqlMonikerImpl	A generic implementation of SqlMoniker.
SqlScopedShuttle	Refinement to SqlShuttle which maintains a stack of scopes.
SqlValidator.Compatible	Deprecated. This class is for backwards-compatibility with the previous incarnation of SqlConformance.
SqlValidatorImpl	Default implementation of SqlValidator.
SqlValidatorImpl.DeleteNamespace	Namespace for a DELETE statement.
SqlValidatorImpl.DmlNamespace	Common base class for DML statement namespaces.
SqlValidatorImpl.Expander	Converts an expression into canonical form by fully-qualifying any identifiers.
SqlValidatorImpl.FunctionParamInfo	Utility object used to maintain information about the parameters in a function call.
SqlValidatorImpl.IdInfo
SqlValidatorImpl.InsertNamespace	Namespace for an INSERT statement.
SqlValidatorImpl.MergeNamespace	Namespace for a MERGE statement.
SqlValidatorImpl.UpdateNamespace	Namespace for an UPDATE statement.
SqlValidatorUtil	Utility methods related to validation.
SqlValidatorUtil.DeepCopier	Walks over an expression, copying every node, and fully-qualifying every identifier.
TableConstructorNamespace	Namespace for a table constructor VALUES (expr, expr, ...).
UnnestNamespace	Namespace for UNNEST.

Enum Summary

SqlConformance	Enumeration of valid SQL compatiblity modes.
SqlMonikerType	An enumeration of moniker types.
SqlMonotonicity	Enumeration of types of monotonicity.
