List all indexes which use a specific table column

If you need to see which indexes on a table make use of a given column then use:

    T.Name as TableName,
    I.Name as IndexName,
    C.Name as ColumnName
FROM sys.tables T
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 C.column_id = IC.column_id
WHERE T.Name='MyTable'
AND C.Name='MyColumn'

substuting the table name for MyTable and the column name for MyColumn in the above.

This query lists the name of the table, the name of the index and the name of the column.
