Syntax
C#
public class CqlUpdate : CqlCommand

The CqlUpdate type exposes the following members.

Methods
  NameDescription
Public methodBeginExecute
Starts executing the statement async
(Inherited from CqlCommand.)
Public methodBind Obsolete.
Sets the parameter values for the query.

The same amount of values must be provided as parameter markers in the query.

Specify the parameter values by the position of the markers in the query or by name, using a single instance of an anonymous type, with property names as parameter names.

(Inherited from SimpleStatement.)
Public methodBindObjects Obsolete. (Inherited from SimpleStatement.)
Public methodDisableTracing
Disable tracing for the statement.
(Inherited from Statement.)
Public methodEnableTracing
Enables tracing for the statement
(Inherited from Statement.)
Public methodEndExecute
Starts the async executing of the statement
(Inherited from CqlCommand.)
Public methodEquals
Determines whether the specified object is equal to the current object.
(Inherited from Object.)
Public methodExecute
Executes the command using the ISession.
(Inherited from CqlCommand.)
Public methodExecuteAsync (Inherited from CqlCommand.)
Public methodGetHashCode
Serves as the default hash function.
(Inherited from Object.)
Public methodGetTable (Inherited from CqlCommand.)
Public methodGetType
Gets the Type of the current instance.
(Inherited from Object.)
Public methodSetAutoPage
Sets the paging behavior. When set to true (default), the RowSet returned when executing this IStatement will automatically fetch the following result pages. When false, the RowSet returned will only contain the rows contained in the result page and will not fetch additional pages.
(Inherited from Statement.)
Public methodSetConsistencyLevel (Inherited from CqlCommand.)
Public methodSetIdempotence
Sets whether this statement is idempotent.

Idempotence of the statement plays a role in ISpeculativeExecutionPolicy. If a statement is not idempotent, the driver will not schedule speculative executions for it.

(Inherited from Statement.)
Public methodSetOutgoingPayload
Sets a custom outgoing payload for this statement. Each time this statement is executed, this payload will be included in the request. Once it is set using this method, the payload should not be modified.
(Inherited from Statement.)
Public methodSetPageSize
Sets the page size for this query. The page size controls how much resulting rows will be retrieved simultaneously (the goal being to avoid loading too much results in memory for queries yielding large results). Please note that while value as low as 1 can be used, it is highly discouraged to use such a low value in practice as it will yield very poor performance. If in doubt, leaving the default is probably a good idea.

Also note that only SELECT queries ever make use of that setting.

the page size to use. If set to 0 or less, the default value will be used. To disable paging of the result set, use int.MaxValue

Return Value

Type: 
this Query object.
(Inherited from Statement.)
Public methodSetPagingState
Sets the paging state, a token representing the current page state of query used to continue paging by retrieving the following result page. Setting the paging state will disable automatic paging.
(Inherited from Statement.)
Public methodSetQueryString (Inherited from SimpleStatement.)
Public methodSetQueryTrace (Inherited from CqlCommand.)
Public methodSetReadTimeoutMillis
Overrides the default per-host read timeout ReadTimeoutMillis for this statement.
(Inherited from Statement.)
Public methodSetRetryPolicy
Sets the retry policy to use for this query.

The default retry policy, if this method is not called, is the one returned by Policies#RetryPolicy in the cluster configuration. This method is thus only useful in case you want to punctually override the default policy for this request.

(Inherited from Statement.)
Public methodSetRoutingKey
Set the routing key for this query.

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

If the partition key for the query is composite, use the #setRoutingKey(ByteBuffer...) method instead to build the routing key.

(Inherited from SimpleStatement.)
Public methodSetRoutingValues
Sets the partition key values in order to route the query to the correct replicas.

For simple partition keys, set the partition key value.

For composite partition keys, set the multiple the partition key values in correct order.

(Inherited from SimpleStatement.)
Public methodSetSerialConsistencyLevel (Inherited from CqlCommand.)
Public methodSetTimestamp (Inherited from CqlCommand.)
Public methodSetTTL
Sets the time for data in a column to expire (TTL) for INSERT and UPDATE commands .
(Inherited from CqlCommand.)
Public methodToString (Overrides RegularStatementToString.)

Properties
  NameDescription
Public propertyAutoPage
Determines if the RowSet returned when executing this IStatement will automatically fetch the following result pages. Defaults to true.
(Inherited from Statement.)
Public propertyConsistencyLevel
Gets the consistency level for this query.
(Inherited from Statement.)
Public propertyExpression (Inherited from CqlCommand.)
Public propertyIsIdempotent
Determines if this statement is idempotent, i.e. whether it can be applied multiple times without changing the result beyond the initial application.

Idempotence of the statement plays a role in ISpeculativeExecutionPolicy. If a statement is not idempotent, the driver will not schedule speculative executions for it.

When the property is null, the driver will use the default value from the GetDefaultIdempotence.
(Inherited from Statement.)
Public propertyIsTracing
Gets whether tracing is enabled for this query or not.
(Inherited from Statement.)
Public propertyOutgoingPayload
Gets custom payload for that will be included when executing this Statement.
(Inherited from Statement.)
Public propertyPageSize
Gets query's page size.
(Inherited from Statement.)
Public propertyPagingState (Inherited from Statement.)
Public propertyQueryString
Gets the query string.
(Inherited from CqlCommand.)
Public propertyQueryTrace (Inherited from CqlCommand.)
Public propertyQueryValues (Inherited from CqlCommand.)
Public propertyReadTimeoutMillis
Gets the per-host read timeout for this statement.

When the value is 0 or lower, the default value from the socket options will be used.

(Inherited from Statement.)
Public propertyRetryPolicy
Gets the retry policy sets for this query, if any.
(Inherited from Statement.)
Public propertyRoutingKey (Inherited from SimpleStatement.)
Public propertySerialConsistencyLevel
Gets the serial consistency level for this query.
(Inherited from Statement.)
Public propertySkipMetadata (Inherited from Statement.)
Public propertyTimestamp
Gets the timestamp associated with this statement execution.
(Inherited from Statement.)
