Syntax

public class BoundStatement : Statement

The BoundStatement type exposes the following members.

Constructors

	Name	Description
	BoundStatement	Initializes a new instance of the Cassandra.BoundStatement class
	BoundStatement(PreparedStatement)	Creates a new BoundStatement from the provided prepared statement.

Properties

	Name	Description
	Keyspace	Returns the keyspace this query operates on, based on the PreparedStatement metadata. The keyspace returned is used as a hint for token-aware routing. (Overrides StatementKeyspace.)
	PreparedStatement	Gets the prepared statement on which this BoundStatement is based.
	RoutingKey	Gets the routing key for this bound query. This method will return a non-null value if: either all the TableColumns composing the partition key are bound variables of this BoundStatement. The routing key will then be built using the values provided for these partition key TableColumns. or the routing key has been set through PreparedStatement.SetRoutingKey for the PreparedStatement this statement has been built from. Otherwise, null is returned. Note that if the routing key has been set through PreparedStatement.SetRoutingKey, that value takes precedence even if the partition key is part of the bound variables. (Overrides StatementRoutingKey.)

Methods

	Name	Description
	SetRoutingKey	Set the routing key for this query. This method allows to manually provide a routing key for this BoundStatement. It is thus optional since the routing key is only an hint for token aware load balancing policy but is never mandatory.
