_օ的SQL语句Q推荐收?br />在网上经常{,常常看到有些Zؓ(f)?jin)求得某些SQL语句而焦头烂?现在我特别把自己收藏的一些比较精典的SQL拿出来和大家分n一?br />
1. 行列转换--普?br />
假设有张学生成W?CJ)如下
Name  (tng) Subject  (tng) Result
张三  (tng) 语文  (tng)  (tng) 80
张三  (tng) 数学  (tng)  (tng) 90
张三  (tng) 物理  (tng)  (tng) 85
李四  (tng) 语文  (tng)  (tng) 85
李四  (tng) 数学  (tng)  (tng) 92
李四  (tng) 物理  (tng)  (tng) 82

惛_? (tng)
姓名  (tng) 语文  (tng) 数学  (tng) 物理
张三  (tng) 80  (tng) 90  (tng) 85
李四  (tng) 85  (tng) 92  (tng) 82

declare @sql varchar(4000)
set @sql = ''select Name''
select @sql = @sql + '',sum(case Subject when ''''''+Subject+'''''' then Result end) [''+Subject+'']''
from (select distinct Subject from CJ) as a
select @sql = @sql+'' from test group by name''
exec(@sql)

2. 行列转换--合ƈ

有表A,
id pid
1  (tng) 1
1  (tng) 2
1  (tng) 3
2  (tng) 1
2  (tng) 2
3  (tng) 1
如何化成表B:
id pid
1 1,2,3
2 1,2
3 1

创徏一个合q的函数
create function fmerg(@id int)
returns varchar(8000)
as
begin
declare @str varchar(8000)
set @str=''''
select @str=@str+'',''+cast(pid as varchar) from 表A where id=@id set @str=right(@str,len(@str)-1)
return(@str)
End
go

--调用自定义函数得到结?br />select distinct id,dbo.fmerg(id) from 表A

3. 如何取得一个数据表的所有列?br />
Ҏ(gu)如下Q先从SYSTEMOBJECTpȝ表中取得数据表的SYSTEMID,然后再SYSCOLUMN表中取得该数据表的所有列名?br />SQL语句如下Q?br />declare @objid int,@objname char(40)
set @objname = ''tablename''
select @objid = id from sysobjects where id = object_id(@objname)
select ''Column_name'' = name from syscolumns where id = @objid order by colid

是不是太单了(jin)Q?呵呵 不过l常用阿.

4. 通过SQL语句来更改用L(fng)密码

修改别h?需要sysadmin role  (tng)
EXEC sp_password NULL, ''newpassword'', ''User''

如果帐号为SA执行EXEC sp_password NULL, ''newpassword'', sa

5. 怎么判断Z个表的哪些字D不允许为空Q?br />
select COLUMN_NAME from INFORMATION_SCHEMA.COLUMNS where IS_NULLABLE=''NO'' and TABLE_NAME=tablename

6. 如何在数据库里找到含有相同字D늚表？
a. 查已知列名的情况
SELECT b.name as TableName,a.name as columnname
From syscolumns  (tng) a INNER JOIN  (tng) sysobjects b  (tng)
ON a.id=b.id  (tng)
AND b.type=''U''  (tng)
AND a.name=''你的字段名字''

b. 未知列名查所有在不同表出现过的列?br />Select o.name As tablename,s1.name As columnname
From syscolumns s1, sysobjects o
Where s1.id = o.id
 (tng) And o.type = ''U''
 (tng) And Exists (
 (tng)  (tng) Select 1 From syscolumns s2  (tng)
 (tng)  (tng) Where s1.name = s2.name  (tng)
 (tng)  (tng) And s1.id <> s2.id
 (tng)  (tng) )

7. 查询Wxxx行数?br />
假设id是主键：(x)
select *
from (select top xxx * from yourtable) aa
where not exists(select 1 from (select top xxx-1 * from yourtable) bb where aa.id=bb.id)

如果使用游标也是可以?
fetch absolute [number] from [cursor_name]
行数为绝对行?br />
8. SQL Server日期计算
a. 一个月的第一?br />SELECT DATEADD(mm, DATEDIFF(mm,0,getdate()), 0)
b. 本周的星期一
SELECT DATEADD(wk, DATEDIFF(wk,0,getdate()), 0)
c. 一q的W一?br />SELECT DATEADD(yy, DATEDIFF(yy,0,getdate()), 0)
d. 季度的第一?br />SELECT DATEADD(qq, DATEDIFF(qq,0,getdate()), 0)
e. 上个月的最后一?
SELECT dateadd(ms,-3,DATEADD(mm, DATEDIFF(mm,0,getdate()), 0))
f. d的最后一?br />SELECT dateadd(ms,-3,DATEADD(yy, DATEDIFF(yy,0,getdate()), 0))
g. 本月的最后一?br />SELECT dateadd(ms,-3,DATEADD(mm, DATEDIFF(m,0,getdate())+1, 0))
h. 本月的第一个星期一
select DATEADD(wk, DATEDIFF(wk,0,  (tng)  (tng)  (tng)  (tng)  (tng)  (tng)  (tng)  (tng)  (tng)  (tng)  (tng)  (tng)  (tng)  (tng)  (tng)  (tng)  (tng)  (tng)  (tng)
 (tng)  (tng)  (tng)  (tng)  (tng)  (tng)  (tng)  (tng)  (tng)  (tng) dateadd(dd,6-datepart(day,getdate()),getdate())  (tng)  (tng)
 (tng)  (tng)  (tng)  (tng)  (tng)  (tng)  (tng)  (tng)  (tng)  (tng)  (tng)  (tng)  (tng)  (tng)  (tng)  (tng)  (tng)  (tng)  (tng)  (tng)  (tng)  (tng)  (tng)  (tng)  (tng)  (tng)  (tng)  (tng)  (tng)  (tng)  (tng)  (tng) ), 0)  (tng)  (tng)
i. 本年的最后一?br />SELECT dateadd(ms,-3,DATEADD(yy, DATEDIFF(yy,0,getdate())+1, 0))?br />-----------------------------------------------------------------------
1.按姓氏笔L?
Select * From TableName Order By CustomerName Collate Chinese_PRC_Stroke_ci_as

2.数据库加?
select encrypt(''原始密码'')
select pwdencrypt(''原始密码'')
select pwdcompare(''原始密码'',''加密后密?') = 1--相同Q否则不相同 encrypt(''原始密码'')
select pwdencrypt(''原始密码'')
select pwdcompare(''原始密码'',''加密后密?') = 1--相同Q否则不相同

3.取回表中字段:
declare @list varchar(1000),@sql nvarchar(1000)
select @list=@list+'',''+b.name from sysobjects a,syscolumns b where a.id=b.id and a.name=''表A''
set @sql=''select ''+right(@list,len(@list)-1)+'' from 表A''
exec (@sql)

4.查看盘分区:
EXEC master..xp_fixeddrives

5.比较A,B表是否相{?
if (select checksum_agg(binary_checksum(*)) from A)
 (tng) =
 (tng) (select checksum_agg(binary_checksum(*)) from B)
print ''相等''
else
print ''不相{?'

6.杀掉所有的事g探察器进E?
DECLARE hcforeach CURSOR GLOBAL FOR SELECT ''kill ''+RTRIM(spid) FROM master.dbo.sysprocesses
WHERE program_name IN(''SQL profiler'',N''SQL 事g探查?')
EXEC sp_msforeach_worker ''?''

7.记录搜烦(ch):
开头到N条记?br />Select Top N * From ?br />-------------------------------
N到M条记?要有ȝ(ch)引ID)
Select Top M-N * From ?Where ID in (Select Top M ID From ? Order by ID Desc
----------------------------------
N到结记?br />Select Top N * From ?Order by ID Desc

8.如何修改数据库的名称:
sp_renamedb ''old_name'', ''new_name''

9Q获取当前数据库中的所有用戯
select Name from sysobjects where xtype=''u'' and status>=0

10Q获取某一个表的所有字D?br />select name from syscolumns where id=object_id(''表名'')

11Q查看与某一个表相关的视图、存储过E、函?br />select a.* from sysobjects a, syscomments b where a.id = b.id and b.text like ''%表名%''

12Q查看当前数据库中所有存储过E?br />select name as 存储q程名称 from sysobjects where xtype=''P''

13Q查询用户创建的所有数据库
select * from master..sysdatabases D where sid not in(select sid from master..syslogins where name=''sa'')
或?br />select dbid, name AS DB_NAME from master..sysdatabases where sid <> 0x01

14Q查询某一个表的字D和数据cd
select column_name,data_type from information_schema.columns
where table_name = ''表名''

[n].[标题]:
Select * From TableName Order By CustomerName

[n].[标题]:
Select * From TableName Order By CustomerName
