Question :
what all select queries are running against a particular table ?
SQL queries used to refer data for a particular table ?
Solution : This following script will show you all the queries that have run against a particular table since the last time SQL Server was started.
| SELECT DISTINCT TOP 500 ProcedureName = OBJECT_SCHEMA_NAME(sqt.objectid) + '.' + OBJECT_NAME(sqt.objectid) ,SQLStatement = SUBSTRING( sqt.Text ,(qs.statement_start_offset/2)+1 ,CASE qs.statement_end_offset WHEN -1 THEN DATALENGTH(sqt.text) ELSE qs.statement_end_offset END - (qs.statement_start_offset/2) + 1 ) ,DiskReads = qs.total_physical_reads -- The worst reads, disk reads ,MemoryReads= qs.total_logical_reads --Logical Reads are memory reads ,ExecutionCount = qs.execution_count ,CPUTime = qs.total_worker_time ,DiskWaitAndCPUTime = qs.total_elapsed_time ,MemoryWrites = qs.max_logical_writes ,DateCached = qs.creation_time ,DatabaseName = DB_Name(sqt.dbid) ,LastExecutionTime = qs.last_execution_time ,sre.* FROM sys.dm_exec_query_stats AS qs CROSS APPLY sys.dm_exec_sql_text(qs.sql_handle) AS sqt CROSS APPLY sys.dm_sql_referenced_entities( OBJECT_SCHEMA_NAME(sqt.objectid) + '.' + OBJECT_NAME(sqt.objectid) , 'OBJECT' ) sre WHERE sqt.dbid = db_id() -- Filter by current database id AND sre.referenced_schema_name + '.' + sre.referenced_entity_name = 'dbo.UnSparsed' |
This query can also be useful, where DBA are not not involved at application level we need to find out what all SQL queries are running against a particular table or when we defining indexes, we wanted to know what all select queries are running against a particular table.
Note : DMV [sys.dm_sql_referenced_entities] is new DMV, which introduced in SQL Server 2008, thus this query will not work in SQL Server 2005. Approx 46 new DMVs are newly added in SQL Server 2008.
