對(duì)mysql代碼進(jìn)行閱讀的時(shí)候，發(fā)現(xiàn)需要添加注釋：
mysql注釋符有三種：
1、#…? 2、”-?-?…”? 3、/…/
依次測試：
1、#…
mysql>?select?*?from?person;????#chazhao +----+------+------+------+-----------+|?id?|?name?|?sex??|?age??|?addr??????| +----+------+------+------+-----------+|??1?|?Jone?|?fema?|???27?|?xianggang?| |??2?|?Lily?|?fema?|???25?|?taiwan????| |??3?|?Bobe?|?male?|???25?|?ximan?????||??4?|?Kity?|?fama?|???20?|?beijing???| +----+------+------+------+-----------+
2、”- – …”
mysql>?select?*?from?person;????--chazhao +----+------+------+------+-----------+|?id?|?name?|?sex??|?age??|?addr??????| +----+------+------+------+-----------+|??1?|?Jone?|?fema?|???27?|?xianggang?| |??2?|?Lily?|?fema?|???25?|?taiwan????| |??3?|?Bobe?|?male?|???25?|?ximan?????||??4?|?Kity?|?fama?|???20?|?beijing???| +----+------+------+------+-----------+
3、/*…*/
mysql>?select?*/*chazhoa*/?from?person;?--chazhao +----+------+------+------+-----------+|?id?|?name?|?sex??|?age??|?addr??????| +----+------+------+------+-----------+|??1?|?Jone?|?fema?|???27?|?xianggang?| |??2?|?Lily?|?fema?|???25?|?taiwan????| |??3?|?Bobe?|?male?|???25?|?ximan?????||??4?|?Kity?|?fama?|???20?|?beijing???| +----+------+------+------+-----------+
