Liste de toutes les colonnes d'index et d'index dans la base de données SQL Server

Comment obtenir une liste de toutes les colonnes d'index et d'index dans SQL Server 2005+? Le plus proche que j'ai pu obtenir est:

select s.name, t.name, i.name, c.name from sys.tables t
inner join sys.schemas s on t.schema_id = s.schema_id
inner join sys.indexes i on i.object_id = t.object_id
inner join sys.index_columns ic on ic.object_id = t.object_id
inner join sys.columns c on c.object_id = t.object_id and
        ic.column_id = c.column_id

where i.index_id > 0    
 and i.type in (1, 2) -- clustered & nonclustered only
 and i.is_primary_key = 0 -- do not include PK indexes
 and i.is_unique_constraint = 0 -- do not include UQ
 and i.is_disabled = 0
 and i.is_hypothetical = 0
 and ic.key_ordinal > 0

order by ic.key_ordinal

Ce n'est pas exactement ce que je veux.
Ce que je veux, c'est répertorier tous les index définis par l'utilisateur ( ce qui signifie qu'il n'y a pas d'index qui prennent en charge les contraintes uniques et les clés primaires ) avec toutes les colonnes (classées selon leur apparence dans la définition de l'index) plus autant de métadonnées que possible.

Il existe deux vues de catalogue "sys" que vous pouvez consulter:

select * from sys.indexes

select * from sys.index_columns

Ceux-ci vous donneront à peu près toutes les informations que vous pourriez souhaiter sur les indices et leurs colonnes.

EDIT: Cette requête se rapproche assez de ce que vous recherchez:

SELECT 
     TableName = t.name,
     IndexName = ind.name,
     IndexId = ind.index_id,
     ColumnId = ic.index_column_id,
     ColumnName = col.name,
     ind.*,
     ic.*,
     col.* 
FROM 
     sys.indexes ind 
INNER JOIN 
     sys.index_columns ic ON  ind.object_id = ic.object_id and ind.index_id = ic.index_id 
INNER JOIN 
     sys.columns col ON ic.object_id = col.object_id and ic.column_id = col.column_id 
INNER JOIN 
     sys.tables t ON ind.object_id = t.object_id 
WHERE 
     ind.is_primary_key = 0 
     AND ind.is_unique = 0 
     AND ind.is_unique_constraint = 0 
     AND t.is_ms_shipped = 0 
ORDER BY 
     t.name, ind.name, ind.index_id, ic.index_column_id;

Vous pouvez utiliser le sp_helpindexpour afficher tous les index d'une table.

EXEC sys.sp_helpindex @objname = N'User' -- nvarchar(77)

Et pour tous les index, vous pouvez parcourir sys.objectspour obtenir tous les index de chaque table.

Rien de ce qui précède n'a fait le travail pour moi, mais cela fait:

Si vos noms contiennent des espaces, ajoutez des crochets autour d'eux dans les scripts de création.

Lorsque la dernière colonne Clé est entièrement nulle, vous savez qu'aucune ne manque.

Le filtrage des clés primaires, etc., comme dans la demande d'origine, est trivial.

REMARQUE: faites attention à cette solution car elle ne distingue pas les colonnes indexées et incluses.

--Court et doux:

SELECT OBJECT_SCHEMA_NAME(T.[object_id],DB_ID()) AS [Schema],  
  T.[name] AS [table_name], I.[name] AS [index_name], AC.[name] AS [column_name],  
  I.[type_desc], I.[is_unique], I.[data_space_id], I.[ignore_dup_key], I.[is_primary_key], 
  I.[is_unique_constraint], I.[fill_factor],    I.[is_padded], I.[is_disabled], I.[is_hypothetical],

Hé les gars, je ne suis pas passé par là mais j'ai obtenu ce que je voulais dans la requête postée par l'auteur original.

Je l'ai utilisé (sans conditions / filtres) pour mon besoin mais cela a donné des résultats incorrects

Le principal problème était que les résultats obtenaient un produit croisé sans condition de jointure sur index_id

SELECT S.NAME SCHEMA_NAME,T.NAME TABLE_NAME,I.NAME INDEX_NAME,C.NAME COLUMN_NAME
  FROM SYS.TABLES T
       INNER JOIN SYS.SCHEMAS S

       INNER JOIN SYS.COLUMNS C
    ON C.OBJECT_ID  = T.OBJECT_ID
   **AND IC.INDEX_ID    = I.INDEX_ID**
   AND IC.COLUMN_ID = C.COLUMN_ID
 WHERE 1=1

ORDER BY I.NAME,I.INDEX_ID,IC.KEY_ORDINAL

J'ai eu besoin d'obtenir des index particuliers, leurs colonnes d'index et leurs colonnes incluses également. Voici la requête que j'ai utilisée:

SELECT INX.[name] AS [Index Name]

Ce qui suit est similaire à sp_helpindex tablename

select T.name as TableName, I.name as IndexName, AC.Name as ColumnName, I.type_desc as IndexType 
from sys.tables as T inner join sys.indexes as I on T.[object_id] = I.[object_id] 
   inner join sys.index_columns as IC on IC.[object_id] = I.[object_id] and IC.[index_id] = I.[index_id] 
   inner join sys.all_columns as AC on IC.[object_id] = AC.[object_id] and IC.[column_id] = AC.[column_id] 
order by T.name, I.name

Sur la base de la réponse acceptée et de deux autres questions ^{1 , 2,} j'ai assemblé la requête suivante:

SELECT
    QUOTENAME(t.name) AS TableName,
    QUOTENAME(i.name) AS IndexName,
    i.is_primary_key,
    i.is_unique,
    i.is_unique_constraint,
    STUFF(REPLACE(REPLACE((

        FROM sys.index_columns AS ic
        INNER JOIN sys.columns AS c ON ic.object_id = c.object_id AND ic.column_id = c.column_id
        WHERE ic.object_id = i.object_id AND ic.index_id = i.index_id AND ic.is_included_column = 0
        ORDER BY ic.key_ordinal
        FOR XML PATH
    ), '<row>', ', '), '</row>', ''), 1, 2, '') AS KeyColumns,
    STUFF(REPLACE(REPLACE((
        SELECT QUOTENAME(c.name) AS [data()]
        FROM sys.index_columns AS ic
        INNER JOIN sys.columns AS c ON ic.object_id = c.object_id AND ic.column_id = c.column_id
        WHERE ic.object_id = i.object_id AND ic.index_id = i.index_id AND ic.is_included_column = 1
        ORDER BY ic.index_column_id
        FOR XML PATH
    ), '<row>', ', '), '</row>', ''), 1, 2, '') AS IncludedColumns,
    u.user_seeks,
    u.user_scans,
    u.user_lookups,
    u.user_updates
FROM sys.tables AS t
INNER JOIN sys.indexes AS i ON t.object_id = i.object_id
LEFT JOIN sys.dm_db_index_usage_stats AS u ON i.object_id = u.object_id AND i.index_id = u.index_id
WHERE t.is_ms_shipped = 0
AND i.type <> 0

Cette requête renvoie des résultats tels que ceux ci-dessous qui affichent la liste des index, leurs colonnes et leur utilisation. Très utile pour déterminer quel indice fonctionne mieux que d'autres:

cela fonctionnera:

DECLARE @IndexInfo  TABLE (index_name         varchar(250)
                          ,index_description  varchar(250)
                          ,index_keys         varchar(250)
                          )

INSERT INTO @IndexInfo
exec sp_msforeachtable 'sp_helpindex ''?'''
select * from @IndexInfo

cela ne reurn le nom de la table et vous obtiendrez des avertissements pour toutes les tables sans index, si c'est un problème, vous pouvez créer une boucle sur les tables qui ont des index comme celui-ci:

DECLARE @IndexInfoTemp  TABLE (index_name         varchar(250)
                              ,index_description  varchar(250)
                              ,index_keys         varchar(250)
                              )

DECLARE @IndexInfo  TABLE (table_name         sysname

                          )

DECLARE @Tables Table (RowID       int not null identity(1,1)
                      ,TableName   sysname 
                      )
DECLARE @MaxRow       int
DECLARE @CurrentRow   int
DECLARE @CurrentTable sysname

INSERT INTO @Tables
    SELECT
        DISTINCT t.name 
        FROM sys.indexes i
            INNER JOIN sys.tables t ON i.object_id = t.object_id
        WHERE i.Name IS NOT NULL
SELECT @MaxRow=@@ROWCOUNT,@CurrentRow=1

WHILE @CurrentRow<=@MaxRow
BEGIN

    SELECT @CurrentTable=TableName FROM @Tables WHERE RowID=@CurrentRow

    INSERT INTO @IndexInfoTemp
    exec sp_helpindex @CurrentTable

    INSERT INTO @IndexInfo
            (table_name   , index_name , index_description , index_keys)
        SELECT
            @CurrentTable , index_name , index_description , index_keys
        FROM @IndexInfoTemp

    DELETE FROM @IndexInfoTemp

    SET @CurrentRow=@CurrentRow+1

END --WHILE
SELECT * from @IndexInfo

MODIFIER
si vous le souhaitez, vous pouvez filtrer les données, voici quelques exemples (ceux-ci fonctionnent pour l'une ou l'autre méthode):

SELECT * FROM @IndexInfo WHERE index_description NOT LIKE '%primary key%'
SELECT * FROM @IndexInfo WHERE index_description NOT LIKE '%nonclustered%' AND index_description  LIKE '%clustered%'
SELECT * FROM @IndexInfo WHERE index_description LIKE '%unique%'

order by 1,2,3

C'est une façon de reculer dans les index. Vous pouvez utiliser SHOWCONTIG pour évaluer la fragmentation. Il répertorie tous les index de la base de données ou de la table, ainsi que les statistiques. Je vous préviens que sur une grande base de données, cela peut durer longtemps. Pour moi, l'un des avantages de cette approche est que vous n'avez pas besoin d'être administrateur pour l'utiliser.

--Afficher les informations de fragmentation sur tous les index d'une base de données

SET NOCOUNT ON
USE pubs
DBCC SHOWCONTIG WITH ALL_INDEXES
GO

... désactivez NOCOUNT lorsque vous avez terminé

--Afficher les informations de fragmentation sur tous les index d'une table

SET NOCOUNT ON

DBCC SHOWCONTIG (authors) WITH ALL_INDEXES

--Afficher les informations de fragmentation sur un index spécifique

SET NOCOUNT ON

Puis-je hasarder une autre réponse à cette question saturée?

Il s'agit d'une refonte libérale de la réponse de @marc_s, mélangée à des éléments de @Tim Ford, dans le but d'avoir un ensemble de résultats plus propre et plus simple et un affichage final et une commande pour mes besoins actuels.

J'ai trouvé celui-ci, qui me donne l'aperçu exact dont j'ai besoin. Ce qui est utile, c'est que vous obtenez une ligne par index dans laquelle les colonnes d'index sont agrégées.

Étant donné que votre profil indique que vous utilisez .NET, vous pouvez utiliser des objets gérés par le serveur (SMO) par programmation ... sinon l'une des réponses ci-dessus est fantastique.

Tout d'abord, veuillez noter que toutes les requêtes ci-dessus peuvent manquer ou incorporer par erreur les colonnes INCLUDE des indices. Il manque également dans certains le bon ordre et / ou l'option ASC / DESC des colonnes.

Modification de la requête ci-dessus par jona. En passant, dans la plupart des bases de données que j'utilise, j'installe ma propre fonction d'agrégat CLR CONCATENATE, donc le code ci-dessous dépend de quelque chose comme ça. Les instructions SQL ci-dessus se réduisent à un niveau beaucoup plus facile à maintenir:

SELECT
  s.[name] AS [schema_name]
, t.[name] AS [table_name]
, i.[name] AS [index_name]
, dbo.Concatenate(CASE WHEN ic.[key_ordinal] > 0 AND ic.[is_descending_key] = 1 THEN c.[name] + ' DESC' WHEN key_ordinal > 0 THEN c.[name] ELSE NULL END,',',1) AS [columns]
, dbo.Concatenate(CASE WHEN ic.[is_included_column] = 1 THEN c.[name] ELSE NULL END,',',1) AS [includes]
FROM
  sys.tables t
INNER JOIN
  sys.schemas s ON t.[schema_id] = s.[schema_id]
INNER JOIN
  sys.indexes i ON i.[object_id] = t.[object_id]
INNER JOIN
  sys.index_columns ic ON ic.[object_id] = t.[object_id] AND ic.index_id = i.index_id
INNER JOIN
  sys.columns c ON c.[object_id] = t.[object_id] AND ic.column_id = c.column_id
GROUP BY
  s.[name]
, t.[name]
, i.[name]
ORDER BY
  s.[name]
, t.[name]
, i.[name]

Il existe de nombreux agrégats de concaténation si votre environnement autorise l'ajout de fonctions basées sur CLR.

Pour les colonnes uniques par index:

select s.name, t.name, i.name, i.index_id,c.name,c.column_id
 from sys.schemas s
inner join sys.tables t on t.schema_id = s.schema_id
inner join sys.indexes i on i.object_id = t.object_id
inner join sys.index_columns ic on ic.object_id = t.object_id
    and ic.index_id=i.index_id
inner join sys.columns c on c.object_id = t.object_id 
    and ic.column_id = c.column_id
where i.object_id = object_id('previous.account_1')  
order by index_id,column_id

Voici la meilleure façon de procéder:

SELECT sys.tables.object_id, sys.tables.name as table_name, sys.columns.name as column_name, sys.indexes.name as index_name,
sys.indexes.is_unique, sys.indexes.is_primary_key
