Posted 2020-12-09 暗黑银狐

 

创建数据库[BCVote].[dbo].[m_vote_record] 的索引 名称为m_vote_recordIPIndex

CREATE INDEX m_vote_recordIPIndex
ON [BCVote].[dbo].[m_vote_record] (ip)

查询数据库中的所有索引

SELECT CASE
WHEN t.[type] = \'U\' THEN \'表\'
WHEN t.[type] = \'V\' THEN \'视图\'
END AS \'类型\',
SCHEMA_NAME(t.schema_id) + \'.\' + t.[name] AS \'(表/视图)名称\',
i.[name] AS 索引名称,
SUBSTRING(column_names, 1, LEN(column_names) - 1) AS \'列名\',
CASE
WHEN i.[type] = 1 THEN
\'聚集索引\'
WHEN i.[type] = 2 THEN
\'非聚集索引\'
WHEN i.[type] = 3 THEN
\'XML索引\'
WHEN i.[type] = 4 THEN
\'空间索引\'
WHEN i.[type] = 5 THEN
\'聚簇列存储索引\'
WHEN i.[type] = 6 THEN
\'非聚集列存储索引\'
WHEN i.[type] = 7 THEN
\'非聚集哈希索引\'
END AS \'索引类型\',
CASE
WHEN i.is_unique = 1 THEN
\'唯一\'
ELSE
\'不唯一\'
END AS \'索引是否唯一\'
