mysqldump如何只備份表結構

用--no-data選項，例如:
C:\Users\duansf\Desktop>mysqldump -uroot -p123456 --no-data --databases test > test.sql


test.sql內容如下:
-- MySQL dump 10.13  Distrib 5.5.13, for Win32 (x86)
--
-- Host: localhost    Database: test
-- ------------------------------------------------------
-- Server version 5.5.13
