Private Attributes
LimitNodeType	type = LimitNodeType::UNSET
idx_t	constant_integer = 0
	Integer value, if value is a constant non-percentage.

	Percentage value, if value is a constant percentage.
unique_ptr< Expression >	expression
	Expression in case node is not constant.

Member Function Documentation

Type()

LimitNodeType duckdb::BoundLimitNode::Type ( ) const

inline

                               {
        return type;
    }

GetExpression()

unique_ptr< Expression > & duckdb::BoundLimitNode::GetExpression ( )

inline

Returns a pointer to the expression - should only be used for limit-agnostic optimizations. Prefer using the methods above in other scenarios.

                                            {
        return expression;
    }
