Liste aller Index- und Indexspalten in SQL Server DB

Question

Wie erhalte ich eine Liste aller Index- und Indexspalten in SQL Server 2005+? Am ehesten konnte ich folgendes herausfinden:

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

Das ist nicht gerade das, was ich will.
Was ich möchte, ist, alle benutzerdefinierten Indizes aufzulisten, ( was bedeutet, dass es keine Indizes gibt, die eindeutige Beschränkungen und Primärschlüssel unterstützen ) mit allen Spalten (geordnet nach der Reihenfolge, in der sie in der Indexdefinition erscheinen) und möglichst vielen Metadaten.

Answer 1

Arbeitslösung für SQL Server 2014. Ich habe hier nur eine Handvoll Ausgabefelder aufgenommen, aber Sie können so viele hinzufügen, wie Sie möchten.

SELECT
    o.object_id AS objectId
    ,o.name AS objectName
    ,i.index_id AS indexId
    ,i.name AS indexName
    ,i.type_desc AS typeDesc
    ,ic.index_column_id AS indexColumnId
    ,ic.key_ordinal AS keyOrdinal
    ,ic.is_included_column AS isIncludedColumn
    ,ic.column_id AS columnId
    ,c.name AS columnName
FROM {database}.sys.objects AS o
    INNER JOIN {database}.sys.columns AS c ON
        c.object_id = o.object_id
        AND o.type = 'U'
    INNER JOIN {database}.sys.indexes AS i ON
        i.object_id = o.object_id
    INNER JOIN {database}.sys.index_columns AS ic ON
        ic.object_id = i.object_id
        AND ic.index_id = i.index_id
        AND ic.column_id = c.column_id
ORDER BY
    o.object_id
    ,i.index_id
    ,ic.index_column_id

Answer 2

Ich habe die Antwort von KFD9 aktualisiert.

Ich habe ihre Version angepasst, um die include-Spezifikation zu unterstützen und indexkey_property nicht zu verwenden. Abgelehnt

Dadurch erhalten Sie eine Anweisung zum Erstellen und Löschen von Indizes und Beschränkungen.

with indexes as (
    SELECT
      schema_name(schema_id) as SchemaName, OBJECT_NAME(si.object_id) as TableName, si.name as IndexName,
      (CASE is_primary_key WHEN 1 THEN 'PK' ELSE '' END) as PK,
      (CASE is_unique WHEN 1 THEN '1' ELSE '0' END)+' '+
      (CASE si.type WHEN 1 THEN 'C' WHEN 3 THEN 'X' ELSE 'B' END)+' ' as 'Type',  -- B=basic, C=Clustered, X=XML
      (select string_agg(CAST('[' + c.name + ']' + case when is_descending_key = 1 then ' DESC' else '' end AS NVARCHAR(MAX)), ',') within group (order by index_column_id) 
         from sys.index_columns ic JOIN sys.columns c on ic.column_id = c.column_id and ic.object_id = c.object_id where ic.index_id = si.index_id and ic.object_id = si.object_id and ic.is_included_column = 0) Cols,
      (select string_agg(CAST('[' + c.name + ']' + case when is_descending_key = 1 then ' DESC' else '' end AS NVARCHAR(MAX)), ',') within group (order by index_column_id) 
         from sys.index_columns ic JOIN sys.columns c on ic.column_id = c.column_id and ic.object_id = c.object_id where ic.index_id = si.index_id and ic.object_id = si.object_id and ic.is_included_column = 1) IncludedCols,
      (select count(*) from sys.index_columns ic where ic.index_id = si.index_id and ic.object_id = si.object_id) IndexColsCount
    FROM sys.indexes as si
    LEFT JOIN sys.objects as so on so.object_id=si.object_id
    WHERE index_id>0 -- omit the default heap
      and OBJECTPROPERTY(si.object_id,'IsMsShipped')=0 -- omit system tables
      and not (schema_name(schema_id)='dbo' and OBJECT_NAME(si.object_id)='sysdiagrams') -- omit sysdiagrams
)
SELECT SchemaName, TableName, IndexName,
  (CASE pk
    WHEN 'PK' THEN 'ALTER '+
     'TABLE ['+SchemaName+'].['+TableName+'] ADD CONSTRAINT ['+IndexName+'] PRIMARY KEY'+
     (CASE substring(Type,3,1) WHEN 'C' THEN ' CLUSTERED' ELSE '' END)
    ELSE 'CREATE '+
     (CASE substring(Type,1,1) WHEN '1' THEN 'UNIQUE ' ELSE '' END)+
     (CASE substring(Type,3,1) WHEN 'C' THEN 'CLUSTERED ' ELSE '' END)+
     'INDEX ['+IndexName+'] ON ['+SchemaName+'].['+TableName+']'
    END)+
  ' ('+Cols+')'+
  isnull(' include ('+IncludedCols+')', '')+
  '' as CreateIndex,
    CASE pk
    WHEN 'PK' THEN 'ALTER '+
     'TABLE ['+SchemaName+'].['+TableName+'] DROP CONSTRAINT ['+IndexName+'] '
    ELSE 'DROP INDEX ['+IndexName+'] ON ['+SchemaName+'].['+TableName + ']'
    END AS DropIndex,
    IndexColsCount
FROM indexes
ORDER BY SchemaName,TableName,IndexName

Answer 3

Die richtige ist hier (Alle oben genannten Beiträge geben kartesisches Produkt Ergebnis, wenn wir mehr als einen Index auf einer Tabelle haben)

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 
                                  AND i.index_id = ic.index_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
 AND  t.name = 'DimCustomer'
order by ic.key_ordinal
