A prepared statement, the statement is pre-compiled and it's more efficient to execute the statement for multiple times.
In addition, this kind of statement provides protection against SQL injection attacks.
From a prepared statement you can

  
use query to create and execute a PreparedQuery
  
use cursor to create a Cursor
  
use createStream to create a RowStream

 NOTE: This class has been automatically generated from the original non RX-ified interface using Vert.x codegen. /**
