我正在尝试使用SQL缺失索引功能;但是....我不是DBO或管理员。我可以访问一个数据库。有没有办法只为没有提升权限的单个数据库运行它
SELECT
migs.avg_total_user_cost * (migs.avg_user_impact / 100.0) * (migs.user_seeks + migs.user_scans) AS improvement_measure,
'CREATE INDEX [missing_index_' + CONVERT (varchar, mig.index_group_handle) + '_' + CONVERT (varchar, mid.index_handle)
+ '_' + LEFT (PARSENAME(mid.statement, 1), 32) + ']'
+ ' ON ' + mid.statement
+ ' (' + ISNULL (mid.equality_columns,'')
+ CASE WHEN mid.equality_columns IS NOT NULL AND mid.inequality_columns IS NOT NULL THEN ',' ELSE '' END
+ ISNULL (mid.inequality_columns, '')
+ ')'
+ ISNULL (' INCLUDE (' + mid.included_columns + ')', '') AS create_index_statement,
migs.*, mid.database_id, mid.[object_id]
FROM sys.dm_db_missing_index_groups mig
INNER JOIN sys.dm_db_missing_index_group_stats migs ON migs.group_handle = mig.index_group_handle
INNER JOIN sys.dm_db_missing_index_details mid ON mig.index_handle = mid.index_handle
WHERE migs.avg_total_user_cost * (migs.avg_user_impact / 100.0) * (migs.user_seeks + migs.user_scans) > 10
ORDER BY migs.avg_total_user_cost * migs.avg_user_impact * (migs.user_seeks + migs.user_scans) DESC

dm_db_missing_index_details
动态视图中包含Database Id
。
WHERE migs.avg_total_user_cost * ( migs.avg_user_impact / 100.0 ) * ( migs.user_seeks + migs.user_scans ) > 10
AND mid.database_ID = Db_id('Database name') --Here
注意: Users
必须获得VIEW SERVER STATE
权限或任何暗示VIEW SERVER STATE
权限才能访问查询中使用的所有三种动态视图的权限

在where子句中添加以下内容:
AND mid.database_ID = Db_id('Your Database name')
