Package org.apache.calcite.sql.type

SQL type system.

Interface Summary

Interface	Description
ExtraSqlTypes	Holds constants associated with SQL types introduced after the earliest version of Java supported by Farrago (this currently means anything introduced in JDK 1.6 or later).
JavaToSqlTypeConversionRules.ColumnList	Make this public when needed.
SqlOperandTypeChecker	Strategy interface to check for allowed operand types of an operator call.
SqlOperandTypeInference	Strategy to infer unknown types of the operands of an operator call.
SqlReturnTypeInference	Strategy interface to infer the type of an operator call from the type of the operands.
SqlSingleOperandTypeChecker	SqlSingleOperandTypeChecker is an extension of SqlOperandTypeChecker for implementations which are capable of checking the type of a single operand in isolation.
SqlTypeName.PrecScale	Flags indicating precision/scale combinations.
SqlTypeTransform	Strategy to transform one type to another.

Class Summary

Class	Description
AbstractSqlType	Abstract base class for SQL implementations of RelDataType.
ArraySqlType	SQL array type.
AssignableOperandTypeChecker	AssignableOperandTypeChecker implements SqlOperandTypeChecker by verifying that the type of each argument is assignable to a predefined set of parameter types (under the SQL definition of "assignable").
BasicSqlType	BasicSqlType represents a standard atomic SQL type (excluding interval types).
ComparableOperandTypeChecker	Type checking strategy which verifies that types have the required attributes to be used as arguments to comparison operators.
CompositeOperandTypeChecker	This class allows multiple existing SqlOperandTypeChecker rules to be combined into one rule.
CompositeSingleOperandTypeChecker	Allows multiple SqlSingleOperandTypeChecker rules to be combined into one rule.
CursorReturnTypeInference	Returns the rowtype of a cursor of the operand at a particular 0-based ordinal position.
ExplicitOperandTypeInference	ExplicitOperandTypeInferences implements SqlOperandTypeInference by explicitly supplying a type for each parameter.
ExplicitReturnTypeInference	A SqlReturnTypeInference which always returns the same SQL type.
FamilyOperandTypeChecker	Operand type-checking strategy which checks operands for inclusion in type families.
InferTypes	Strategies for inferring operand types.
IntervalSqlType	IntervalSqlType represents a standard SQL datetime interval type.
JavaToSqlTypeConversionRules	JavaToSqlTypeConversionRules defines mappings from common Java types to corresponding SQL types.
LiteralOperandTypeChecker	Parameter type-checking strategy type must be a literal (whether null is allowed is determined by the constructor).
MapSqlType	SQL map type.
MatchReturnTypeInference	Returns the first type that matches a set of given SqlTypeNames.
MultisetOperandTypeChecker	Parameter type-checking strategy types must be [nullable] Multiset, [nullable] Multiset and the two types must have the same element type
MultisetSqlType	MultisetSqlType represents a standard SQL2003 multiset type.
ObjectSqlType	ObjectSqlType represents an SQL structured user-defined type.
OperandsTypeChecking	Strategies to check for allowed operand types of an operator call.
OperandTypes	Strategies for checking operand types.
OperandTypes.PeriodOperandTypeChecker	Operand type checker that accepts period types: PERIOD (DATETIME, DATETIME) PERIOD (DATETIME, INTERVAL) [ROW] (DATETIME, DATETIME) [ROW] (DATETIME, INTERVAL)
OrdinalReturnTypeInference	Returns the type of the operand at a particular 0-based ordinal position.
ReturnTypes	A collection of return-type inference strategies.
SameOperandTypeChecker	Parameter type-checking strategy where all operand types must be the same.
SameOperandTypeExceptLastOperandChecker	Parameter type-checking strategy where all operand types except last one must be the same.
SetopOperandTypeChecker	Parameter type-checking strategy for a set operator (UNION, INTERSECT, EXCEPT).
SqlOperandCountRanges	Helpers for SqlOperandCountRange.
SqlOperandCountRanges.RangeImpl	Implementation of SqlOperandCountRange.
SqlReturnTypeInferenceChain	Strategy to infer the type of an operator call from the type of the operands by using a series of SqlReturnTypeInference rules in a given order.
SqlTypeAssignmentRules	Rules that determine whether a type is assignable from another type.
SqlTypeAssignmentRules.Builder	Keeps state while maps are building build.
SqlTypeExplicitPrecedenceList	SqlTypeExplicitPrecedenceList implements the RelDataTypePrecedenceList interface via an explicit list of SqlTypeName entries.
SqlTypeFactoryImpl	SqlTypeFactoryImpl provides a default implementation of RelDataTypeFactory which supports SQL types.
SqlTypeFactoryImpl.UnknownSqlType	The unknown type.
SqlTypeTransformCascade	Strategy to infer the type of an operator call from the type of the operands by using one SqlReturnTypeInference rule and a combination of SqlTypeTransforms
SqlTypeTransforms	SqlTypeTransforms defines a number of reusable instances of SqlTypeTransform.
SqlTypeUtil	Contains utility methods used during SQL validation or type derivation.
TableFunctionReturnTypeInference	TableFunctionReturnTypeInference implements rules for deriving table function output row types by expanding references to cursor parameters.

Enum Summary

CompositeOperandTypeChecker.Composition	How operands are composed.
SqlOperandTypeChecker.Consistency	Strategy used to make arguments consistent.
SqlTypeFamily	SqlTypeFamily provides SQL type categorization.
SqlTypeName	Enumeration of the type names which can be used to construct a SQL type.
SqlTypeName.Limit	Limit.
