Missing Index Detection

Missing Index Detection is a SQL statement in the Administration category. SQL Server: dynamic management view that shows recommended indexes the optimizer would use. The syntax is SELECT * FROM sys.dm_db_missing_index_details;. It returns missing index recommendations. A typical example: SELECT migs.avg_total_user_cost * migs.avg_user_impact * (migs.user_seeks + migs.user_scans) AS improvement_measure, 'CREATE INDEX idx_' + ' ON ' + mid.statement + ' (' + ISNULL(mid.equality_columns, '') + CASE WHEN mid.inequality_columns IS NOT NULL THEN ',' + mid.inequality_columns ELSE '' END + ')' + ISNULL(' INCLUDE (' + mid.included_columns + ')', '') AS create_index_statement FROM sys.dm_db_missing_index_groups mig JOIN sys.dm_db_missing_index_group_stats migs ON migs.group_handle = mig.index_group_handle JOIN sys.dm_db_missing_index_details mid ON mig.index_handle = mid.index_handle ORDER… A close relative is CREATE USER, which creates a new database user account. A close relative is GRANT, which grants specific privileges (SELECT, INSERT, UPDATE, DELETE, ALL) to a user on a database/table. A close relative is REVOKE, which removes previously granted privileges from a user.
