列出包含列的所有索引(非键)

Question

我曾尝试过sp_helpindex但它显示的索引列不是包含的列.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
