#include "mozIStorageBaseStatement.idl"

 * An asynchronous SQL statement.  This differs from mozIStorageStatement by
 * only being usable for asynchronous execution.  (mozIStorageStatement can
 * be used for both synchronous and asynchronous purposes.)  This specialization
 * for asynchronous operation allows us to avoid needing to acquire
 * synchronization primitives also used by the asynchronous execution thread.
 * In contrast, mozIStorageStatement may need to acquire the primitives and
 * consequently can cause the main thread to lock for extended intervals while
 * the asynchronous thread performs some long-running operation.

interface mozIStorageAsyncStatement : mozIStorageBaseStatement {
   * 'params' provides a magic JS helper that lets you assign parameters by
   * name.  Unlike the helper on mozIStorageStatement, you cannot enumerate
   * in order to find out what parameters are legal.
   * This does not work for BLOBs.  You must use an explicit binding API for
   * that.
   * example:
   * = 1;
   *  stmt.params["bar"] = 2;
   *  let argName = "baz";
   *  stmt.params[argName] = 3;
   * readonly attribute nsIMagic params;
