> PREPARE and EXECUTE statements provide an ability to create a parameterized query and re-use it to execute with different parameters.
> e.g.
> {code:sql}
> PREPARE pcount from 
>     select count(*) from src where key > ?;
> EXECUTE pcount using 200;
> PREPARE pquery2 from 
>    select count(*) from daysales where dt=? and customer=?;
> EXECUTE pquery2 using '2001-01-01',1;
> {code}
