sql-server diseño - Lista de todas las columnas de índice e índice en SQL Server DB




select creando (22)

¿Cómo obtengo una lista de todas las columnas de índice e índice en SQL Server 2005+? Lo más cerca que pude conseguir es:

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

Que no es exactamente lo que quiero.
Lo que quiero es, enumerar todos los índices definidos por el usuario, (lo que significa que no hay índices que admitan restricciones y claves primarias únicas ) con todas las columnas (ordenadas por cómo aparecen en la definición del índice) más la mayor cantidad de metadatos posible.


Answers

Hay dos vistas de catálogo "sys" que puedes consultar:

select * from sys.indexes

select * from sys.index_columns

Esos le darán casi cualquier información que pueda desear sobre los índices y sus columnas.

EDIT: esta consulta se está acercando bastante a lo que estás buscando:

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;

--Corto y dulce:

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], 
  I.[allow_row_locks], I.[allow_page_locks], IC.[is_descending_key], IC.[is_included_column] 
FROM sys.[tables] AS T  
  INNER JOIN sys.[indexes] I ON T.[object_id] = I.[object_id]  
  INNER JOIN sys.[index_columns] IC ON I.[object_id] = IC.[object_id] 
  INNER JOIN sys.[all_columns] AC ON T.[object_id] = AC.[object_id] AND IC.[column_id] = AC.[column_id] 
WHERE T.[is_ms_shipped] = 0 AND I.[type_desc] <> 'HEAP' 
ORDER BY T.[name], I.[index_id], IC.[key_ordinal]   

Ya que su perfil indica que está utilizando .NET, podría usar los objetos administrados por el servidor (SMO) programáticamente ... de lo contrario, cualquiera de las respuestas anteriores es fantástica.


He utilizado la siguiente consulta cuando tuve este requisito ...

SELECT 
    TableName = t.name,
    ColumnId = col.column_id, 
    ColumnName = col.name,
    DataType = ty.name,
    MaxSize = ty.max_length,
    IsNullable = CASE WHEN (col.is_nullable = 1) THEN 'Y' END,
    IsIdentity = CASE WHEN (col.is_identity = 1) THEN 'Y' END,
    IsPrimaryKey = CASE WHEN (ic.column_id = col.column_id) THEN 'Y' END,
    IsForeignKey = CASE WHEN (fkc.parent_column_id = col.column_id) THEN 'Y' END,
    IsDefault = CASE WHEN (dc.parent_column_id = col.column_id) THEN 'Y' END
FROM 
    sys.tables t
INNER JOIN 
     sys.columns col ON t.object_id = col.object_id 
LEFT JOIN
    sys.indexes ind ON t.object_id = ind.object_id 
LEFT JOIN 
     sys.index_columns ic ON ic.index_id=ind.index_id AND ic.object_id = col.object_id and ic.column_id = col.column_id
LEFT JOIN sys.foreign_key_columns fkc
                ON fkc.parent_object_id = col.object_id AND fkc.parent_column_id=col.column_id
LEFT JOIN sys.default_constraints dc
                ON dc.parent_object_id = col.object_id AND dc.parent_column_id=col.column_id
LEFT JOIN
     sys.types ty on ty.user_type_id = col.user_type_id

WHERE
    --t.name='<TABLENAME>'
    t.schema_id = 10    --SCHEMA ID
    AND ind.is_primary_key=1    
ORDER BY
    t.name, ColumnId

Hola chicos, no pasé, pero obtuve lo que quería en la consulta publicada por el autor original.

Lo usé (sin condiciones / filtros) para mi requerimiento pero dio resultados incorrectos

El principal problema fue el resultado de obtener un producto cruzado sin condición de unión en 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
    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.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

Lo siguiente funciona en SQL Server 2014/2016, así como en cualquier base de datos SQL de Microsoft Azure.

Basado en el código de Tim Ford, esta es la respuesta correcta:

  select tab.[name]  as [table_name],
         idx.[name]  as [index_name],
         allc.[name] as [column_name],
         idx.[type_desc],
         idx.[is_unique],
         idx.[data_space_id],
         idx.[ignore_dup_key],
         idx.[is_primary_key],
         idx.[is_unique_constraint],
         idx.[fill_factor],
         idx.[is_padded],
         idx.[is_disabled],
         idx.[is_hypothetical],
         idx.[allow_row_locks],
         idx.[allow_page_locks],
         idxc.[is_descending_key],
         idxc.[is_included_column],
         idxc.[index_column_id]

     from sys.[tables] as tab

    inner join sys.[indexes]       idx  on tab.[object_id] =  idx.[object_id]
    inner join sys.[index_columns] idxc on idx.[object_id] = idxc.[object_id] and  idx.[index_id]  = idxc.[index_id]
    inner join sys.[all_columns]   allc on tab.[object_id] = allc.[object_id] and idxc.[column_id] = allc.[column_id]

    where tab.[name] Like '%table_name%'
      and idx.[name] Like '%index_name%'
    order by tab.[name], idx.[index_id], idxc.[index_column_id]

esto funcionará:

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

esto no devuelve el nombre de la tabla y recibirá advertencias para todas las tablas sin un índice; si eso es un problema, puede crear un bucle sobre las tablas que tienen índices como este:

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

DECLARE @IndexInfo  TABLE (table_name         sysname
                          ,index_name         varchar(250)

                          ,index_keys         varchar(250)
                          )

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 @[email protected]@ROWCOUNT,@CurrentRow=1

WHILE @CurrentRow<[email protected]
BEGIN

    SELECT @CurrentTable=TableName FROM @Tables WHERE [email protected]

    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 @[email protected]+1

END --WHILE
SELECT * from @IndexInfo

EDITAR
Si lo desea, puede filtrar los datos, aquí hay algunos ejemplos (estos funcionan para cualquiera de los métodos):

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%'

La siguiente consulta incluye toda la información pertinente para los índices definidos por el usuario, (sin índices para restricciones únicas y claves primarias) con todas las columnas:

¿Puedo aventurar otra respuesta a esta pregunta saturada?

Esta es una modificación progresiva de la respuesta de @marc_s, combinada con algunas cosas de @Tim Ford, con el objetivo de tener un conjunto de resultados y una visualización final más limpios y sencillos, y realizar el pedido para mi necesidad actual.

Se me ocurrió esta, que me da la descripción exacta que necesito. Lo que ayuda es que se obtiene una fila por índice en el que se agregan las columnas del índice.

Si sus nombres incluyen espacios, agregue corchetes alrededor de ellos en los scripts de creación.

Cuando la última columna de la clave es nula, sabes que no falta ninguna.

Filtrar las claves primarias, etc. como en la solicitud original es trivial.

NOTA: Tenga cuidado con esta solución, ya que no distingue las columnas indexadas e incluidas.


Según la respuesta aceptada y otras dos preguntas 1 , 2 , he reunido la siguiente consulta:

SELECT
    sys.indexes.name AS IndexName,
    sys.tables.name AS TableName,
    REPLACE((
        SELECT sys.columns.name + CASE WHEN is_descending_key = 1 THEN ' DESC' ELSE '' END AS [data()]
        FROM sys.index_columns
        INNER JOIN sys.columns ON sys.index_columns.object_id = sys.columns.object_id AND sys.index_columns.column_id = sys.columns.column_id
        WHERE sys.index_columns.object_id = sys.indexes.object_id AND sys.index_columns.index_id = sys.indexes.index_id AND sys.index_columns.is_included_column = 0
        ORDER BY sys.index_columns.key_ordinal
        FOR XML PATH('')
    ), ' ', ', ') AS KeyColumns,
    REPLACE((
        SELECT sys.columns.name AS [data()]
        FROM sys.index_columns
        INNER JOIN sys.columns ON sys.index_columns.object_id = sys.columns.object_id AND sys.index_columns.column_id = sys.columns.column_id
        WHERE sys.index_columns.object_id = sys.indexes.object_id AND sys.index_columns.index_id = sys.indexes.index_id AND sys.index_columns.is_included_column = 1
        ORDER BY sys.index_columns.index_column_id
        FOR XML PATH('')
    ), ' ', ', ') AS IncludedColumns,
    sys.dm_db_index_usage_stats.user_updates,
    sys.dm_db_index_usage_stats.user_seeks,
    sys.dm_db_index_usage_stats.user_scans,
    sys.dm_db_index_usage_stats.user_lookups,
    sys.dm_db_index_usage_stats.user_seeks + sys.dm_db_index_usage_stats.user_scans + sys.dm_db_index_usage_stats.user_lookups AS total_usage
FROM sys.indexes
LEFT JOIN sys.tables ON sys.indexes.object_id = sys.tables.object_id
LEFT JOIN sys.dm_db_index_usage_stats ON sys.indexes.object_id = sys.dm_db_index_usage_stats.object_id AND sys.indexes.index_id = sys.dm_db_index_usage_stats.index_id
WHERE sys.indexes.type <> 0 AND sys.tables.is_ms_shipped = 0

Esta consulta devuelve resultados como a continuación, que muestra la lista de índices, sus columnas y su uso. Muy útil para determinar qué índice se está desempeñando mejor que otros:


Primero, tenga en cuenta que todas las consultas anteriores pueden omitirse o incorporar erróneamente las columnas INCLUDE de los índices. También falta en algunos el orden correcto y / o la opción ASC / DESC de las columnas.

Modificado la consulta anterior por jona. Además, en muchas de las bases de datos que uso, instalo mi propia función de agregado CLR CONCATENATE, por lo que el código siguiente depende de que algo así esté presente. Las declaraciones de SQL anteriores se reducen a mucho más mantenibles:

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]

Existen muchos agregados de concatenación si su entorno permite que se agreguen funciones basadas en CLR.


Solo tenga en cuenta que si va a utilizar cualquiera de las consultas anteriores para crear secuencias de comandos de sus índices, debe incorporar la columna filter_definition de la tabla sys.indexes en sus consultas para obtener la definición de filtro de índices no agrupados en SQL 2008+
