    • createPreparedStatement

      public reactor.core.publisher.Mono<com.datastax.oss.driver.api.core.cql.PreparedStatement> createPreparedStatement(ReactiveSession session) throws com.datastax.oss.driver.api.core.DriverException
      Description copied from interface: ReactivePreparedStatementCreator
      Create a statement in this session. Allows implementations to use PreparedStatements. The ReactiveCqlTemplate will attempt to cache the PreparedStatements for future use without the overhead of re-preparing on the entire cluster.
      Specified by:
      createPreparedStatement in interface ReactivePreparedStatementCreator
      Parameters:
      session - Session to use to create statement, must not be null.
      Returns:
      a prepared statement.
      Throws:
      com.datastax.oss.driver.api.core.DriverException - there is no need to catch DriverException that may be thrown in the implementation of this method. The ReactiveCqlTemplate class will handle them.

    • bindValues

      public com.datastax.oss.driver.api.core.cql.BoundStatement bindValues(com.datastax.oss.driver.api.core.cql.PreparedStatement ps) throws com.datastax.oss.driver.api.core.DriverException
      Description copied from interface: PreparedStatementBinder
      Bind parameter values on the given PreparedStatement.
      Specified by:
      bindValues in interface PreparedStatementBinder
      Parameters:
      ps - the PreparedStatement to invoke setter methods on.
      Throws:
      com.datastax.oss.driver.api.core.DriverException - if a DriverException is encountered (i.e. there is no need to catch DriverException)

    • getCql

      Specified by:
      getCql in interface CqlProvider
      Returns:
      the CQL string.
