  --列出SQL SERVER 所有表字段名主键,类型,长度,小数位数等信息

  --在查询分析器里运行即可,可以生成一个表,导出到EXCEL中

  -- ======================================================

  SELECT

  (case when a.colorder=1 then d.name else '' end)表名,

  a.colorder 字段序号,

  a.name 字段名,

  (case when COLUMNPROPERTY( a.id,a.name,'IsIdentity')=1 then '√'else '' end) 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) 主键,

  b.name 类型,

  a.length 占用字节数,

  COLUMNPROPERTY(a.id,a.name,'PRECISION') as 长度,

  isnull(COLUMNPROPERTY(a.id,a.name,'Scale'),0) as 小数位数,

  (case when a.isnullable=1 then '√'else '' end) 允许空,

  isnull(e.text,'') 默认值,

  isnull(g.[value],'') AS 字段说明  

  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 sysproperties g

  on a.id=g.id AND a.colid = g.smallid 

  order by a.id,a.colorder

  -------------------------------------------------------------------------------------------------

  列出SQL SERVER 所有表、字段定义,类型,长度,一个值等信息

  并导出到Excel 中
