SQL Server 数据库基本使用技巧

use master; #显示数据库

select top 3 * from spt_values; #显示去前3行

select * from test where id2 like '%1010%'; #查询test表中的id2字段 中带有1010的列

==================================================================

create table test(
id1 varchar(10),
id2 varchar(10),
name varchar(20)
);
insert into test values('100','1001','ccc');
insert into test values('100','1002','bbb');
insert into test values('100','1003','aaa');
insert into test values('101','1010','fff');
insert into test values('101','1011','ddd');
insert into test values('101','1012','eee');

查询语句：

select * from dbo.test order by id1 ,CHARINDEX(id2,'1011,1012,1010,1003,1002,1001,');

==================================================================

--举个例子，表名为zwj，字段为sp，查询sp字段中含有'所有'的语句为
select * from zwj where sp like '%所有%'

--表名为zwj，字段为sp，查询sp字段中含有'所'或'有'的语句为
select * from zwj where sp like '%所%' or sp like '%有%'

==================================================================

更新数据

UPDATE 表名称 SET 列名称 = 新值 WHERE 列名称 = 某值

UPDATE TABLE_NAME
SET column_name1 = VALUE WHRER column_name2 = VALUE;

==================================================================
删除字段
DELETE FROM 表名称 WHERE 列名称 = 值；
DELETE FROM Person WHERE LastName = 'Wilson' 删除person 表中的 名称lastname='wilson'的一行数据；
delete from test where id1='200';

EXEC sp_attach_db @dbname = '数据库名称', @filename1 = 'MDF路径',@filename2= 'LOG路径.LDF'  

分离数据库命令：
[sql] view plain copy
EXEC sp_detach_db @dbname = '数据库名称'  

注：要在master下执行。
