如何用Sql语句在数据表中添加字段
分类: dynamic
简介:数据表中添加一个字段的标准SQL语句写法为:alter table 表名 add (字段 字段类型) [ default '输入默认值'] [null/not null]举例:ALTER TABLE employee ADD spbh varchar(20) NOT NULL Default 0意思就是在表employee 中加入 字段spbh,该字段的类型是varchar,大小20,并且不允许为空,初始默认值是0。扩展资料:其他常用sql语句:1、修改数据表中某项字段属性,为其添加备注。语句格式:comment on column 库名.表名.字段名 is '输入的备注'示例: 我要在ers_data库中 test表 document_type字段添加备注,则sql语句为:comment on column ers_data.test.document_type is '文件类型'2、修改数据表中某字段类型。语句格式:alter table 表名 modiy (字段 字段类型 [default '输入默认值' ] [null/not null] ,字段 字段类型 [default '输入默认值' ] [null/not null] ) 修改多个字段用逗号隔开。示例:想要修改一个teacher教师表中字段办公室classroom的类型为char(20),且默认值“办公室”,则对应sql为:ALTER TABLE teacher ALTER COLUMN classroom VARCHAR(20) NOT NULL default "办公室"3、删除数据表中的某字段。语句格式:alter table 表名 drop (字段)示例:删除表student中的字段age,可以用如下sql:alter table student drop age

简介:1老鼠掉进了半满的米缸,意外让它喜不自禁。确定没有危险后,它便开始了在米缸里吃了睡、睡了吃的生活。很快,米缸就要见底了,可它终究还是摆脱不了大米的诱惑,继续留在缸里。最后,米吃完了,它才发现,跳出去只是梦想,一切都无能为力了生活看似平坦,实则藏有玄机,所以我们要居安思危,未雨绸缪,以备不时之需。2第一天,小白兔去钓鱼,一无所获。第二天,它又去钓鱼,还是如此。第三天它刚到,一条大鱼从河里跳出来,大叫:你要是再敢用胡萝卜当鱼饵,我就扁死你。你给的都是你自己“想”给的,而不是对方想要的,学会换位思考,明白别人之所需,许多事情可能就迎刃而解了。3在一次宴会上,马克吐温与一位女士对坐,出于礼貌,说了一声:您真漂亮!那位女士却不领情,高傲地说:可惜我无法同样来赞美您!马克吐温委婉平和地说:那没关系,你可以像我一样,说一句谎话就行了。那位女士羞愧地低下了头你扔下的石头,绊倒的往往是你自己。挖下的坑,往往是自己跳。4一个朋友是医生,一次癌症手术,打开后发现切不了,只好再缝上。去和病人解释情况,那位病人农村来的,听不懂术语,坚持认为手术过了,病就好了。只好让其出院,一年后回访,真的好了,癌细胞消失了。心病难医,乐观的心态是最好的手术。5那年,他坐在咖啡店等朋友,一位女孩走过来问:你是通过王阿姨介绍来相亲的吗?他抬头打量一下她,正是自己喜欢的类型,心想何不将错就错,于是忙答应道:对,请坐。结婚当天,他坦白,当时自己不是去相亲的。老婆笑,说:我也不是去相亲的,只是找个借口和你搭讪……机遇来了,只要方式合理,就快去抓住它。6女生公开投票选班花,相貌平平的小梅发表演说:如果我当选,再过几年,在座的姐妹可以向自己先生骄傲的说,我上大学时,比班花还漂亮!结果,她全票当选!说服别人支持你,不一定要证明你的优秀,而是要证明别人的优秀,人都是这样,禁不住夸奖的。7在高速行驶的火车上,一位老人不小心把刚买的新鞋从窗口掉了一只,周围的人倍感惋惜,不料老人立即把第二只鞋也从窗口扔了下去。这个举动让人大吃一惊。老人解释说:这一只鞋无论多么昂贵,对我而言已经没有用了,如果有谁能捡到一双鞋子,说不定他还能穿呢!注定无法挽回的痛苦,不如早点放弃。8两只老虎,一只在笼子里,一只在荒野中。两只老虎都认为自己所处的环境不好,互相羡慕对方。它们决定交换身份,开始时,十分快乐。但不久,两只老虎都死了:一只饥饿而死,一只忧郁而死有时,人们对自己的幸福熟视无睹,总是把眼睛看向别人的幸福。其实,你所拥有的正是别人所羡慕的。

有种关系,此生难忘
分类: dynamic
简介:茫茫人海,与你擦肩而过的人很多,和你相识的人也不计其数。有血缘关系的亲人就是屈指可数那么几个,除了亲人之外,还有另外一种人,这种人尽管没有血缘关系,但也像亲人一样关心你、爱护你、帮助你,这种人就是朋友。朋友就是你高兴时想见的人,烦恼时想找的人。朋友是可以一起打着伞在雨中漫步,是可以一起在海边沙滩上打个滚儿,是可以一起沉溺于某种音乐遐思,是可以一起徘徊于书海畅游,朋友是有悲伤陪你一起掉眼泪,有欢乐和你一起傻傻的笑……朋友不是先来的人或者认识最久的人,而是那个来了以后再也没有走的人。最值得珍惜的,不是得不到,也不是已失去,而是此刻你所拥有的。经历了太多,不败的只有朋友,用什么来诠释这种特别的东西,我想,是永恒。人生短短几十载,眨眼间便过,抓住的,抓不住的,溜走的,留下的,一些些,都是感动,都是满足,虽曾不满意这些,但经历了太多,也便欣然,留住身边的,便是最好的。打不走的才是朋友,吵不散的才是真爱。将心比心,站在朋友的立场上为他想想,设身处地的去帮助值得去帮助的朋友,毕竟来世间一遭,你我有缘才会相识,下辈子不会再相见了。朋友之间最重要的东西:一颗真心!好朋友就像星星。你不一定每天都能看见他们,但你知道,他们会一直在那里。真心的对待每个对我好的人,滴水之恩,涌泉相报;涌泉之恩,以心相报。朋友不一定常常联系,但也不会忘记,每次偶尔念起,还是感觉那么温暖亲切;朋友是把关怀放在心里,把关注藏在眼底;朋友是相伴走过一段又一段的人生。朋友不一定形影不离,但一定心心相惜。不一定锦上添花,但一定雪中送炭。不一定天天见面,但一定放在心里。一辈子真的不长,该珍惜的彼此珍惜吧!

愿漫漫长路,总有人陪伴左右
分类: dynamic
简介:昨晚下班很晚,可地铁依旧很挤。等了几班车,才挤上了车尾。好不容易找到一个还算宽松的位置站着,正想松口气时,看到一个满脸泪水的姑娘。她没有表情,没有声音,但眼泪一直在流。很想送她一张纸巾,但强按住了快要伸出去的手。这种境况下,她应该不太希望被关注,也不太想被打扰吧。好想此时能有一个她特别亲密的朋友在身边,帮她擦干眼泪,给她一个紧紧地拥抱。可生命中有太多孤独,需要一个人面对。有太多眼泪,需要独自品味。曾经你也经历过这样的时刻吧。悲从心生,怎么也压不住心底的委屈。顾不得身处的环境,也无心顾及周围人的看法。只能用仅剩的理智,控制着自己不要哭出声。多希望在这些时刻,能有一人陪伴在你身边。知你心事,懂你委屈,帮你擦干脸上的泪水。轻声告诉你“想哭就哭,你还有我。”生命是一段旅程,可是很多时候,旅途中的风景没有我们想象中那么美好。总会在某些猝不及防的时刻,用这样或那样的事情,打的人措手不及。而我们只能照单全收,独自消化,停一段时间后,才能收拾好心情后,重新出发。在这段旅程中,你一边努力,一边迷茫。陪在你身边的人,总是只陪了一段,就去了不同的方向。让我感谢命运我的生命总有人匆匆离去太多今天想要去逃避被推进被驱离你是否也一直在寻找?寻找一个人解开你的迷茫,指引你人生的方向,陪你走到旅程尽头,看遍沿途的风景。寻找一个人在大雨中为你撑伞,在黑暗中默默抱紧你,陪你彻夜聊天,陪你开心陪你流泪。虽然常听人说,人生而孤独。但还是希望你能找到这么一个人。往后余生,不论遇到什么,都不用一个人孤身面对。漫漫人生路,能有他来作陪。
