sqlserver查找所有包含标示列的表
在数据库中有很多表，其中有些表设置了标示列，请问怎样的语句才可以将这些表名称查询出来，如果可以的话能否查询出所有包含标示列的表以及其字段呢？
请大神帮帮忙，我的水平也就谢谢简单查询更新语句，请大神写的时候尽量给点注释 sqlserver??标识列

SELECT
[表名]=CASE WHEN T.column_id = 1 THEN OBJECT_NAME(T.object_id) ELSE '' END ,
[字段编号]=T.column_id,
[字段名]=T.name,
[主键]=case when exists(SELECT 1 FROM sys.key_constraints where type='PK' and object_id=T.OBJECT_ID) THEN '●' ELSE '' END,
[标识列]=CASE T.is_identity WHEN 1 THEN '●' ELSE '' END,
[计算列]=CASE T.is_computed WHEN 1 THEN '●' ELSE '' END,
[字段类型]=(SELECT name FROM sys.types WHERE user_type_id = T.user_type_id),
[字段长度]= T.PRECISION,
[小数位] = T.Scale,
[允许空] = CASE T.is_nullable WHEN 1 THEN '●' ELSE '' END,
[默认值]= ISNULL((SELECT definition from sys.default_constraints where object_id = T.default_object_id),''),
[字段说明]=(SELECT VALUE FROM sys.extended_properties WHERE major_id = T.OBJECT_ID AND minor_id =T.column_id)
FROM sys.COLUMNS T
INNER JOIN sys.objects O ON T.object_id = O.object_id AND O.type = 'U'
WHERE RIGHT(OBJECT_NAME(T.object_id),3) <> 'Log' AND OBJECT_NAME(T.object_id) <>'AuditDDLEvents' AND OBJECT_NAME(T.object_id) <>'dtproperties'
ORDER BY OBJECT_NAME(T.object_id),T.column_id
