/**
 * Represents a SQL statement that has been prepared by a driver to be executed.
 *
 * This type is not thread safe unless otherwise specified by the driver emitting these.
 *
 * Prepared statements should not be cached by client code. Drivers can implement caching by using
 * the integer identifier passed to [SqlDriver.execute] or [SqlDriver.executeQuery].
 * Client code can pass the same identifier to that method to request that the prepared statement
 * is cached.
