我想列出索引中不包含特定列的所有表,但该列存在于表架构中。
我引用了https://docs.djangoproject.com/en/1.8/ref/models/querysets/,但查询列出了包含所有索引的所有表。
例如,如果表架构包含一列'日期'并且索引不包含列'日期'然后我想在我的结果中列出这个表。

DECLARE @search_column SYSNAME;
SET @search_column = 'Date';
SELECT s.name AS [Schema], t.name AS [Table]
FROM
sys.schemas s
INNER JOIN sys.tables t ON
t.[schema_id] = s.[schema_id]
INNER JOIN sys.columns c ON
c.[object_id] = t.[object_id]
WHERE
c.name = @search_column AND
NOT EXISTS
(
SELECT *
FROM
sys.indexes i
INNER JOIN sys.index_columns ic ON
ic.[object_id] = i.[object_id] AND
ic.index_id = i.index_id
WHERE
i.[object_id] = t.[object_id] AND
ic.column_id = c.column_id
)
ORDER BY
s.name,
t.name;
