查询历史可以通过系统视图查看:

sys.dm_exec_query_stats sys.dm_exec_sql_text sys.dm_exec_query_plan

例如，使用以下查询:

select  top(100)
        creation_time,
        last_execution_time,
        execution_count,
        total_worker_time/1000 as CPU,

        convert(money, (qs.total_elapsed_time))/(execution_count*1000)as [AvgDur],
        total_logical_reads as [Reads],
        total_logical_writes as [Writes],
        total_logical_reads+total_logical_writes as [AggIO],
        convert(money, (total_logical_reads+total_logical_writes)/(execution_count + 0.0)) as [AvgIO],
        [sql_handle],

        total_physical_reads,
        convert(money, total_physical_reads/(execution_count + 0.0)) as [AvgIOPhysicalReads],
        convert(money, total_logical_reads/(execution_count + 0.0)) as [AvgIOLogicalReads],
        convert(money, total_logical_writes/(execution_count + 0.0)) as [AvgIOLogicalWrites],

        query_plan_hash,
        total_rows,
        convert(money, total_rows/(execution_count + 0.0)) as [AvgRows],
        total_dop,
        convert(money, total_dop/(execution_count + 0.0)) as [AvgDop],
        total_grant_kb,
        convert(money, total_grant_kb/(execution_count + 0.0)) as [AvgGrantKb],

        convert(money, total_reserved_threads/(execution_count + 0.0)) as [AvgReservedThreads],
        total_used_threads,
        convert(money, total_used_threads/(execution_count + 0.0)) as [AvgUsedThreads],
        case 
            when sql_handle IS NULL then ' '
            else(substring(st.text,(qs.statement_start_offset+2)/2,(
                case
                    when qs.statement_end_offset =-1 then len(convert(nvarchar(MAX),st.text))*2      
                    else qs.statement_end_offset    
                end - qs.statement_start_offset)/2  ))
        end as query_text,

cross apply sys.dm_exec_sql_text(qs.[sql_handle]) as st

对于查询历史，也有各种第三方解决方案。 我使用Dbeaver的查询管理器: 和SSMS内嵌的SQL Tools中的查询执行历史:

我使用下面的查询来跟踪未启用跟踪分析器的SQL服务器上的应用程序活动。 该方法使用查询存储(SQL Server 2016+)而不是DMV的。这提供了更好的查看历史数据的能力，以及更快的查找。 捕获sp_who/sp_whoisactive无法捕获的短时间运行的查询是非常有效的。

If the queries you are interested in are dynamic queries that fail intermittently, you could log the SQL and the datetime and user in a table at the time the dynamic statement is created. It would be done on a case-by case basis though as it requires specific programming to happen and it takes a littel extra processing time, so do it only for those few queries you are most concerned about. But having a log of the specific statements executed can really help when you are trying to find out why it fails once a month only. Dynamic queries are hard to thoroughly test and sometimes you get one specific input value that just won't work and doing this logging at the time the SQL is created is often the best way to see what specifically wasn in the sql that was built.

系统不会以这种方式记录查询。如果你知道你想提前这么做，你可以使用SQL Profiler来记录将要输入的内容，并在Profiler运行期间跟踪查询。

如果需要，可以通过SQL Profiler监视SQL查询

SELECT deqs.last_execution_time AS [Time], dest.text AS [Query], dest.*
FROM sys.dm_exec_query_stats AS deqs
CROSS APPLY sys.dm_exec_sql_text(deqs.sql_handle) AS dest
WHERE dest.dbid = DB_ID('msdb')
ORDER BY deqs.last_execution_time DESC

这将显示查询运行的时间和日期
