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,

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
