SQL怎么导出字段名

比如数据库名abc 我想把数据库中所有表的字段名都导出来 我只想要字段名 越好粘贴越好

Answer 1

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
