Question

如何查找索引的创建日期。我正在使用SQL2008 R2。我检查了sys.indexes，但它没有创建日期，因此我使用sys.objects加入了查询。问题是索引的对象id和包含该索引的表是相同的。

我正在使用此查询...

select i.name, i.object_id, o.create_date, o.object_id, o.name
from sys.indexes i 
join sys.objects o on i.object_id=o.object_id 
where i.name = 'Index_Name'

谢谢！

Answer 1

对于作为约束的索引，请参阅marc_s'answer

对于其他索引，您必须使用STATS_DATE来获取已分配索引的创建时间（每个索引都有统计信息）

像（未经测试）

之类的东西

SELECT STATS_DATE(OBJECT_ID('MyTable'), 
(SELECT index_id FROM sys.indexes WHERE name = 'Index_Name'))

这依赖于sys.stats链接的sys.indexes

编辑：就任何人都无法找到而言，无法找到答案。遗憾。

Answer 2

简单查询以按降序日期（统计数据）顺序列出索引。此日期是上次统计信息更新的状态，因此仅对最近创建的索引可靠。

select STATS_DATE(so.object_id, index_id) StatsDate
, si.name IndexName
, schema_name(so.schema_id) + N'.' + so.Name TableName
, so.object_id, si.index_id
from sys.indexes si
inner join sys.tables so on so.object_id = si.object_id
order by 1 desc

Answer 3

这是一个相当长的死线程，但是SQLPanda的以下查询为我提供了Azure SQL上非聚集索引所需的信息：

SELECT OBJECT_NAME(i.object_id) AS TableName, i.object_id, i.name, i.type_desc,o.create_date, o.modify_date,o.type,i.is_disabled
FROM   sys.indexes i
        INNER JOIN sys.objects o ON i.object_id = o.object_id
WHERE o.type NOT IN ('S', 'IT')
  AND o.is_ms_shipped = 0 
  AND i.name IS NOT NULL
ORDER BY modify_date DESC

归功于http://www.sqlpanda.com/2013/10/how-to-check-index-creation-date.html

我刚刚添加了修改日期，因为那是我感兴趣的信息。

Answer 4

试试这个：

SELECT 
    i.name 'Index Name',
    o.create_date
FROM 
    sys.indexes i
INNER JOIN 
    sys.objects o ON i.name = o.name
WHERE 
    o.is_ms_shipped = 0
    AND o.type IN ('PK', 'FK', 'UQ')

object_id是指在...上创建索引的表。

Answer 5

select 
    crdate, i.name, object_name(o.id)
from 
    sysindexes i
join 
    sysobjects o ON o.id = i.id 
where 
    i.name = 'My_Index_Name'

Answer 6

创建PK或UK时，SQL Server会自动为该约束创建唯一索引。这些约束的create_date将与相应索引的创建日期相同。

由于sys.indexes视图没有create_date列，因此搜索此类信息绝对没用。此外，此视图中的object_id列永远不会引用相应的约束。它将指向索引所属的表。以下测试将证明这一点：

CREATE TABLE dbo.TEST_T1
(
    COLUMN_1 INT NOT NULL, 
    COLUMN_2 INT NOT NULL,
    CONSTRAINT PK_TEST_T1 PRIMARY KEY (COLUMN_1)
)
GO
WAITFOR DELAY '00:00:01';

ALTER TABLE dbo.TEST_T1
    ADD CONSTRAINT UK_TEST_T1 UNIQUE (COLUMN_2)
GO

SELECT O.name, O.object_id, O.create_date, I.object_id, I.name AS index_name
FROM sys.objects AS O 
    LEFT OUTER JOIN sys.indexes AS I ON O.object_id = i.object_id
WHERE O.name IN ('TEST_T1', 'PK_TEST_T1', 'UK_TEST_T1')

结果是：

name        object_id   create_date             object_id   index_name
PK_TEST_T1  272720024   2015-03-17 11:02:47.197 NULL        NULL
TEST_T1     256719967   2015-03-17 11:02:47.190 256719967   PK_TEST_T1
TEST_T1     256719967   2015-03-17 11:02:47.190 256719967   UK_TEST_T1
UK_TEST_T1  288720081   2015-03-17 11:02:48.207 NULL        NULL

因此，如果您想查看PK或UK索引的create_date，则无需加入sys.indexes。您应该从sys.objects中选择：

SELECT name, object_id, create_date
FROM sys.objects
WHERE name IN ('PK_TEST_T1', 'UK_TEST_T1')
AND type IN ('PK', 'UQ')

结果是：

name        object_id   create_date
PK_TEST_T1  272720024   2015-03-17 11:02:47.197
UK_TEST_T1  288720081   2015-03-17 11:02:48.207

select distinct * from index_history

但索引的主要问题是，当我们重建或重新组织索引时，索引创建日期会更改为上次重建或重组索引的日期。

Answer 8

select OBJECT_NAME(object_id) AS INDEX_NAME,[name], *
from sys.indexes
Where OBJECT_NAME(object_id) NOT LIKE 'sys%' -- to exclude sys indexes
order by INDEX_NAME

这个对我有用。如果8年后神奇地起作用，请回复。：D
