要查看表索引，可以使用如下的SQL语句：

-- 查看表的所有索引EXEC sp_helpindex 'table_name';-- 查看表的索引信息和统计信息SELECT i.name AS index_name,i.type_desc AS index_type,i.is_unique,i.is_primary_key,c.name AS column_name,ic.index_column_id AS column_order,ic.key_ordinal AS key_order,ic.is_descending_keyFROMsys.indexes AS iJOIN sys.index_columns AS ic ON i.object_id = ic.object_id AND i.index_id = ic.index_idJOIN sys.columns AS c ON ic.object_id = c.object_id AND ic.column_id = c.column_idWHEREOBJECT_NAME(i.object_id) = 'table_name'ORDER BYic.index_column_id;

其中，将table_name替换为你要查看的表的名称。第一条SQL语句会显示表的所有索引的详细信息，包括索引名称、列名称、索引类型等。第二条SQL语句将返回更简洁的索引信息，包括索引名称、索引类型、是否唯一、是否主键等。
