MS SQL SERVER导出表结构到Excel

今天准备整理下手里面几个数据库，形成一个表结构文档，方便以后维护使用。

网上找到一个脚本还不错，小小的修改就满足了我的要求，执行完SQL脚本。

在结果就能看到数据库所有表的结构，这个时候只要全选，然后右击出来属性框，选择将结果另存为，这个时候您只要选择导出CSV，然后新建一个Excel表格，在菜单栏选择数据，再选择自文本，后面的大家可以自己的需求自行处理了。

SQL Server脚本：

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,
     字段说明   = isnull(G.[value],''),
     标识       = Case When COLUMNPROPERTY( A.id,A.name,'IsIdentity')=1 Then '√'Else '' End,
     主键       = Case When exists(SELECT 1 FROM sysobjects Where xtype='PK' and parent_obj=A.id and name in (
                      SELECT name FROM sysindexes WHERE indid in( SELECT indid FROM sysindexkeys WHERE id = A.id AND colid=A.colid))) then '√' else '' end,
     类型       = B.name,
     占用字节数 = A.Length,
     长度       = COLUMNPROPERTY(A.id,A.name,'PRECISION'),
     小数位数   = isnull(COLUMNPROPERTY(A.id,A.name,'Scale'),0),
     允许空     = Case When A.isnullable=1 Then '√'Else '' End,
     默认值     = isnull(E.Text,'')
 FROM
     syscolumns A
 Left Join
     systypes B
 On
     A.xusertype=B.xusertype
 Inner Join
     sysobjects D
 On
     A.id=D.id  and D.xtype='U' and  D.name<>'dtproperties'
 Left Join
     syscomments E
 on
     A.cdefault=E.id
 Left Join
 sys.extended_properties  G
 on
     A.id=G.major_id and A.colid=G.minor_id
 Left Join

 sys.extended_properties F
 On
     D.id=F.major_id and F.minor_id=0
     --where d.name='OrderInfo'    --如果只查询指定表,加上此条件
 Order By
     A.id,A.colorder

或者格式更紧凑

SELECT
表名 = CASE WHEN A.COLORDER=1 THEN D.NAME ELSE '' END,
表备注 = CASE WHEN A.COLORDER=1 THEN ISNULL(F.VALUE,'') ELSE '' END,
列序号 = A.COLORDER,
列名称 = A.NAME,
标识 = CASE WHEN COLUMNPROPERTY(A.ID,A.NAME,'ISIDENTITY')=1 THEN '√ ' ELSE '' END,
主键 = CASE WHEN EXISTS(SELECT 1 FROM SYSOBJECTS WHERE XTYPE='PK' AND PARENT_OBJ=A.ID AND NAME IN (
SELECT NAME FROM SYSINDEXES WHERE INDID IN(
SELECT INDID FROM SYSINDEXKEYS WHERE ID=A.ID AND COLID=A.COLID))) THEN '√' ELSE '' END,
类型 = B.NAME,
字节 = A.LENGTH,
长度 = COLUMNPROPERTY(A.ID,A.NAME,'PRECISION'),
小数位 = ISNULL(COLUMNPROPERTY(A.ID,A.NAME,'SCALE'),0),
允许空 = CASE WHEN A.ISNULLABLE=1 THEN '√ 'ELSE '' END,
默认值 = ISNULL(E.TEXT,''),
列备注 = ISNULL(G.[VALUE],'')
FROM
SYSCOLUMNS A
LEFT JOIN SYSTYPES B ON A.XUSERTYPE=B.XUSERTYPE
INNER JOIN SYSOBJECTS D ON A.ID=D.ID AND D.XTYPE='U ' --AND D.NAME<>'DTPROPERTIES'
LEFT JOIN SYSCOMMENTS E ON A.CDEFAULT=E.ID
LEFT JOIN sys.extended_properties G ON A.ID=G.major_id AND A.COLID=G.minor_id
LEFT JOIN sys.extended_properties F ON D.ID=F.major_id AND F.minor_id=0
--where D.NAME='tbname' --查询这个表
ORDER BY A.ID,A.COLORDER

第三种方法

打开SQLServer企业管理器，找到你要导出用户表字段信息的那个数据库，点击工具上的SQL查询分析器，直接copy下面的SQL语句到查询分析器中，点击F5运行。

 

SELECT
(case when a.colorder=1 then d.name else '' end) N'表名',
a.colorder N'字段序号',
a.name N'字段名',
isnull(g.[value],'') AS N'字段说明',
(case when COLUMNPROPERTY( a.id,a.name,'IsIdentity')=1 then '√'else '' end) N'标识',
(case when (SELECT count(*)
FROM sysobjects
WHERE (name in
(SELECT name
FROM sysindexes
WHERE (id = a.id) AND (indid in
(SELECT indid
FROM sysindexkeys
WHERE (id = a.id) AND (colid in
(SELECT colid
FROM syscolumns
WHERE (id = a.id) AND (name = a.name))))))) AND
(xtype = 'PK'))>0 then '√' else '' end) N'主键',
b.name N'类型',
a.length N'占用字节数',
COLUMNPROPERTY(a.id,a.name,'PRECISION') as N'长度',
isnull(COLUMNPROPERTY(a.id,a.name,'Scale'),0) as N'小数位数',
(case when a.isnullable=1 then '√'else '' end) N'允许空',
isnull(e.text,'') N'默认值'

--into ##tx

FROM syscolumns a left join systypes b
on a.xtype=b.xusertype
inner join sysobjects d
on a.id=d.id and d.xtype='U' and d.name<>'dtproperties'
left join syscomments e
on a.cdefault=e.id
left join sys.extended_properties g
on a.id=g.major_id AND a.colid = g.minor_id
order by object_name(a.id),a.colorder

 

      至此，该数据库中的用户字段信息就出来了，然后可以把结果全选，复制到Excel里面、粘贴。
