T-sql 显示表结构和字段信息的sql语句: exec sp_help tablename; ~~使用存储过程 sp_help 显示数据库包含哪些表的sql语句: use yourDBname;select name from sysobjects where xtype='u'; ~~使用系统表 sysobjects 在当前数据库中查询其他数据库的表use shaowu2_2013;select * from ac where acid not in(select acid from sh
Sql Server(sybase): 1.复制表结构: 新建表student2,并且结构同表syn_xj_student一致.Sql语句如下: 2.复制表数据,并排除俩表中相同的数据: insert into syn_xj_student2 select * from syn_xj_student where f_id not in (select f_id from syn_xj_student2) mysql: 1.复制表结构: create table topic like bbs_to
SELECT syscolumns.name,systypes.name,syscolumns.isnullable,syscolumns.length FROM syscolumns, systypes WHERE syscolumns.xusertype = systypes.xusertype AND syscolumns.id= object_id('T_OA_WLWZ_DJB')
进入数据库: mysql> use sunshine_blog;输出: Database changed 查数据库表: mysql> show tables;输出: +-------------------------+ | Tables_in_sunshine_blog | +-------------------------+ | test | | user | +-------------------------+ rows in set (0.00 sec) 建表:auto_incre
sql server 2008抓取方法: --------------------------------------- SELECT 表名 = Case When A.colorder=1 Then D.name Else '' End, 表说明 = Case When A.colorder=1 Then isnull(F.value,'') Else '' End, 字段序号 = A.colorder, 字段名 = A.name, 字段说
只说原理了,具体 可以自己使用程序去生成htm或word文档. 1.首先获取所有的表 SELECT name, id From sysobjects WHERE xtype = 'u' ORDER BY name ASC 2.根据表名查询字段信息 select syscolumns.name, syscolumns.length, systypes.name as typename, sys.extended_properties.[value] AS tname,syscolumns.
判断两个数据库互相不存在的表 select a.TABLE_SCHEMA,a.TABLE_NAME from information_schema.TABLES a where a.TABLE_SCHEMA='db1' and a.TABLE_NAME NOT IN(SELECT b.TABLE_NAME from information_schema.TABLES b where b.TABLE_SCHEMA='db2'); select a.TABLE_SCHEMA,a.TABLE_NAME
oracle --------------------------------------- SELECT case when t.COLUMN_ID=1 then t.table_name end table_name, case when t.COLUMN_ID=1 then t2.comments end table_comments, t.COLUMN_ID,t.colUMN_NAME,t1.comments,case when t3.COLUMN_NAM
select a.name as 列名, a.length as 长度,b.name as 类型 from syscolumns a left join systypes b on a.xtype = b.xtype left join sysobjects c on c.id = a.id -- where c.name = ''
最近在研究PHP,那么就必须涉及到mysql.其中一个功能通过表数据自动生成页面,紧接着发现在一张空表中无法读取数据(因为人家刚刚新建,就是空的没有数据) 延伸出来便是直接查表结构获得字段名,再进行处理. SQL server 和MySQL 搜索表结构语句是不同的:SQL server:select * from syscolumns where id=(select id from sysobjects where name='T_tmp') MySQL: SELECT * FROM INFO
