如何导出SQL所有用户表的字段信息
问题：怎样才能导出SQL所有用户表的字段信息？
解答：请使用下面的Sql语句：
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
