Query packet (Cassandra)

This packet is sent by the client to execute a query.

Properties

• query (string): the text of the query to execute immediately

• consistency (int): the level of consistency for the execution of the query (see Cassandra common flags)

• consistencyName (string, read-only): the level of consistency requested for the execution, as a readable string

• flagSkipMetadata (boolean): if true, the packet does not contain metadata.

• paramValues (list<QueryParameterValue>): the values for the parameters in the query, if any. It is usually easier to use getParameter() and setParameter() -- see below.

• resultPageSize (int): the page size

• pagingState (byte[]): the paging state

• serialConsistency (int): the level of consistency request for the serial phase of conditional updates (see Cassandra common flags)

• serialConsistencyName (string, read-only): the serialConsistency as a readable string

• defaultTimestamp (long): the default timestamp for the query, in microseconds

• keyspaceName (string): the keyspace in which the query should be executed

• nowInSeconds (int): the current time (now) for the execution

Methods

• object getParameter(int): returns the value of the specified parameter (0-based)

• object getParameter(string): returns the value of the specified parameter, if parameters have names

• void setParameter(int, object): sets the value of the specified parameter

• void setParameter(string, object ): sets the value of the specified parameter by name, if parameters have names
