Class SqlOrderBy

java.lang.Object

org.apache.calcite.sql.SqlNode

org.apache.calcite.sql.SqlCall

org.apache.calcite.sql.SqlOrderBy

All Implemented Interfaces:

Cloneable

public class SqlOrderBy
extends SqlCall

Parse tree node that represents an ORDER BY on a query other than a SELECT (e.g. VALUES or UNION).

It is a purely syntactic operator, and is eliminated by SqlValidatorImpl.performUnconditionalRewrites(org.apache.calcite.sql.SqlNode, boolean) and replaced with the ORDER_OPERAND of SqlSelect.

Method Detail

getKind

public SqlKind getKind()

Description copied from class: SqlNode

Returns the type of node this is, or SqlKind.OTHER if it's nothing special.

Overrides:

getKind in class SqlCall

Returns:

a SqlKind value, never null

See Also:

SqlNode.isA(java.util.Set<org.apache.calcite.sql.SqlKind>)

getOperator

public SqlOperator getOperator()

Specified by:

getOperator in class SqlCall

getOperandList

public List<SqlNode> getOperandList()

Description copied from class: SqlCall

Returns the list of operands. The set and order of operands is call-specific.

Note: the proper type would be List<@Nullable SqlNode>, however, it would trigger too many changes to the current codebase.

Specified by:

getOperandList in class SqlCall

Returns:

the list of call operands, never null, the operands can be null
