sql-server - 列出所有包含列的索引（非键）

Question

我曾尝试过sp_helpindex但它显示具有索引的列而不是包含的列。请告诉我如何列出包含列（非键）的所有索引？

Answer 1

针对目录视图尝试此 T-SQL 查询：

SELECT 
    IndexName = i.Name,
    ColName = c.Name
FROM 
    sys.indexes i
INNER JOIN 
    sys.index_columns ic ON ic.object_id = i.object_id AND ic.index_id = i.index_id
INNER JOIN 
    sys.columns c ON c.object_id = ic.object_id AND c.column_id = ic.column_id
WHERE
    ic.is_included_column = 1
ORDER BY 
    i.Name

它基本上检查所有索引 ( sys.indexes)，然后链接到它们的列并检查哪些列被设计为包含列 ( ic.is_included_column = 1)，然后列出所有这些索引和所有这些列。

SELECT 
 OBJECT_NAME(i.[object_id]) TableName ,
 i.[name] IndexName ,
 c.[name] ColumnName ,
 ic.is_included_column ,
 i.index_id ,
 i.type_desc ,
 i.is_unique ,
 i.data_space_id ,
 i.ignore_dup_key ,
 i.is_primary_key ,
 i.is_unique_constraint
FROM 
 sys.indexes i
 JOIN sys.index_columns ic ON ic.object_id = i.object_id and i.index_id = ic.index_id
 JOIN sys.columns c ON ic.object_id = c.object_id AND ic.column_id = c.column_id
ORDER BY 
 tableName ,
 ic.index_id ,
 ic.index_column_id

如果您想要一个可用于获取索引键/非键（包含）列的全局系统存储过程，请运行以下代码

USE master
GO

CREATE PROCEDURE sp_helpcolindex
    @objname NVARCHAR(776)
AS
BEGIN
    SELECT 
        c.Name,
        CASE ic.is_included_column WHEN 0 THEN 'Key' ELSE 'Include' END AS [Type]
    FROM sys.indexes i
    JOIN sys.index_columns ic ON ic.object_id = i.object_id AND ic.index_id = i.index_id
    JOIN sys.columns c ON c.object_id = ic.object_id AND c.column_id = ic.column_id
    WHERE i.name = @objname 
    ORDER BY [Type] DESC
END
GO

EXEC sp_ms_marksystemobject 'sp_helpcolindex' 
GO
