SQLs you need to improve performance of you Azure SQL databases

 Check index fragmentation:

SELECT
 DB_NAME() AS DBName
 ,OBJECT_NAME(ps.object_id) AS TableName
 ,i.name AS IndexName
 ,ips.index_type_desc
 ,ips.avg_fragmentation_in_percent
 FROM sys.dm_db_partition_stats ps
 INNER JOIN sys.indexes i
 ON ps.object_id = i.object_id
 AND ps.index_id = i.index_id
 CROSS APPLY sys.dm_db_index_physical_stats(DB_ID(), ps.object_id, ps.index_id, null, 'LIMITED') ips
 ORDER BY ps.object_id, ps.index_id

List slowest sql executions with QueryPlans (if you save them as .sqlplan you can easily open it in Management Studio)

SELECT  qs.max_worker_time, qs.max_elapsed_time, st.text,
        qp.query_plan,
        qs.*
FROM    (
    SELECT  TOP 50 *
    FROM    sys.dm_exec_query_stats
    ORDER BY total_worker_time DESC
) AS qs
CROSS APPLY sys.dm_exec_sql_text(qs.sql_handle) AS st
CROSS APPLY sys.dm_exec_query_plan(qs.plan_handle) AS qp
WHERE qs.max_worker_time > 300
      OR qs.max_elapsed_time > 300
ORDER BY qs.max_elapsed_time DESC

Next query:
