Consultas para administrar una base de datos SQL Server

En la actualidad muchas personas, que no son DBA, requieren de Consultas Administrativas SQL, para lograr obtener metricas de informacion, por lo cual crearemos un conjunto de informacion con las mas relevantes para mi, mas adelante colocare muchas mas

Consultas Administrativas SQL

Numero 1:

Top N de consultas ejecutadas en una base de datos en Particular, esta genial para realizar auditorias en nuestra base de datos

SELECT TOP 10 execquery.last_execution_time AS [Date Time] ,execsql.TEXT AS [Script] 
FROM sys.dm_exec_query_stats AS execquery 
CROSS APPLY sys.dm_exec_sql_text(execquery.sql_handle) AS execsql WHERE execsql.dbid = DB_ID() 
ORDER BY execquery.last_execution_time DESC

SELECT TOP 10 execquery.last_execution_time AS [Date Time] ,execsql.TEXT AS [Script]

FROM sys.dm_exec_query_stats AS execquery

CROSS APPLY sys.dm_exec_sql_text(execquery.sql_handle) AS execsql WHERE execsql.dbid = DB_ID()

ORDER BY execquery.last_execution_time DESC

Numero 2:

Fechas de objetos modificados en nuestra base de datos

SELECT *
FROM sys.objects
ORDER BY modify_date DESC

SELECT *

FROM sys.objects

ORDER BY modify_date DESC

Numero 3:

Inspeccionar usuarios que estan ejecutando una consulta en tiempo real, genial para saber quien esta usando mas la base de datos y cual es su proceso activo

Numero 4:

Detectar bloqueos en la base de datos, (Imaginen que tienen una consulta y no responde, quiza existe otro proceso usando las mismas tablas y tienen bloqueada la tabla, con esto podras saber si te estan bloquendo tu consulta)
