struct CassStatement
A statement object is an executable query. It represents either a regular (adhoc) statement or a prepared statement. It maintains the queries’ parameter values along with query options (consistency level, paging state, etc.)
Note: Parameters for regular queries are not supported by the binary protocol version 1.
Functions
CassStatement * cass_statement_new
( query, parameter_count )Creates a new query statement.
CassStatement * cass_statement_new_n
( query, query_length, parameter_count )Same as CassStatement::cass_statement_new, but with lengths for string parameters.
CassError cass_statement_reset_parameters
( statement, count )Clear and/or resize the statement’s parameters.
void cass_statement_free
( statement )Frees a statement instance. Statements can be immediately freed after being prepared, executed or added to a batch.
CassError cass_statement_add_key_index
( statement, index )Adds a key index specifier to this a statement. When using token-aware routing, this can be used to tell the driver which parameters within a non-prepared, parameterized statement are part of the partition key.
Use consecutive calls for composite partition keys.
This is not necessary for prepared statements, as the key parameters are determined in the metadata processed in the prepare phase.
CassError cass_statement_set_keyspace
( statement, keyspace )Sets the statement’s keyspace for use with token-aware routing.
This is not necessary for prepared statements, as the keyspace is determined in the metadata processed in the prepare phase.
CassError cass_statement_set_keyspace_n
( statement, keyspace, keyspace_length )Same as CassStatement::cass_statement_set_keyspace, but with lengths for string parameters.
CassError cass_statement_set_consistency
( statement, consistency )Sets the statement’s consistency level.
Default: CASS_CONSISTENCY_LOCAL_ONE
CassError cass_statement_set_serial_consistency
( statement, serial_consistency )Sets the statement’s serial consistency level.
Requires Cassandra: 2.0+
Default: Not set
CassError cass_statement_set_paging_size
( statement, page_size )Sets the statement’s page size.
Requires Cassandra: 2.0+
Default: -1 (Disabled)
CassError cass_statement_set_paging_state
( statement, result )Sets the statement’s paging state. This can be used to get the next page of data in a multi-page query.
Requires Cassandra: 2.0+
CassError cass_statement_set_paging_state_token

Warning: The paging state should not be exposed to or come from untrusted environments. The paging state could be spoofed and potentially used to gain access to other data.
CassError cass_statement_set_timestamp

Requires Cassandra: 2.1+
CassError cass_statement_set_request_timeout
