--結合sys.indexes和sys.index_columns,sys.objects,sys.columns查詢索引所屬的表或視圖的信息
select
  o.name as 表名,
  i.name as 索引名,
  c.name as 列名,
  i.type_desc as 類型描述,
  is_primary_key as 主鍵約束,
  is_unique_constraint as 唯一約束,
  is_disabled as 禁用
from sys.objects o 
inner join sys.indexes i on i.object_id=o.object_id
inner join sys.index_columns ic on ic.index_id=i.index_id and ic.object_id=i.object_id
inner join sys.columns c on ic.column_id=c.column_id and ic.object_id=c.object_id
where o.name='CSEMPL_1'
