用于查找列的依赖索引的SQL查询

Question

如果一个表有为其列'col'创建的索引，则更改该列会给出类似“索引'index1'依赖于列'col'。”

给定表名和列名，如何编写SQL查询以列出该列的依赖索引？

数据库是MSSQL2008R2

谢谢

您可以简单地查询元数据：

SELECT  IndexName = i.Name
FROM    [sys].[index_columns] ic
        INNER JOIN [sys].[columns] c
            ON ic.[object_id] = c.[object_id]
            AND ic.[column_id] = c.[column_id]          
        INNER JOIN [sys].[indexes] i
            ON i.[object_id] = ic.[object_id]
            AND i.[index_id] = ic.[index_id]
WHERE   ic.[object_id] = OBJECT_ID('dbo.TableName')
AND     c.Name = 'ColumnName';
