IStatement Methods

Disable tracing for the statement.

Enables tracing for the statement

Allows this statement to be executed as a different user/role than the one currently authenticated (a.k.a. proxy execution).

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.

Sets the consistency level for the query.

The default consistency level, if this method is not called, is ConsistencyLevel.ONE.

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.

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.

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.

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.

Overrides the default per-host read timeout ReadTimeoutMillis for this statement.

Sets the retry policy to use for this query.

Calling this method is only required when you want to override the default RetryPolicy set in the cluster configuration for this request or the one set in the execution profile (see RetryPolicy) for this request.

Use a IExtendedRetryPolicy implementation to cover all error scenarios.

Sets the serial consistency level for the query. The serial consistency level is only used by conditional updates (so INSERT, UPDATE and DELETE with an IF condition). For those, the serial consistency level defines the consistency level of the serial phase (or "paxos" phase) while the normal consistency level defines the consistency for the "learn" phase, i.e. what type of reads will be guaranteed to see the update right away. For instance, if a conditional write has a regular consistency of QUORUM (and is successful), then a QUORUM read is guaranteed to see that write. But if the regular consistency of that write is ANY, then only a read with a consistency of SERIAL is guaranteed to see it (even a read with consistency ALL is not guaranteed to be enough).

Sets the timestamp associated with this statement execution. If provided, this will replace the server side assigned timestamp as default timestamp. Note that a timestamp in the query itself will still override this timestamp.
