我正在使用以下查询在 SQL Server 2008 上检查它,我得到的错误是
消息 102,级别 15,状态 1,第 13 行 '.' 附近的语法不正确。
询问:
SELECT total_worker_time/execution_count AS AvgCPU
, total_worker_time AS TotalCPU
, total_elapsed_time/execution_count AS AvgDuration
, total_elapsed_time AS TotalDuration
, (total_logical_reads+total_physical_reads)/execution_count AS AvgReads
, (total_logical_reads+total_physical_reads) AS TotalReads
, execution_count
, SUBSTRING
(
st.TEXT, (qs.statement_start_offset/2)+1,
(
(
CASE qs.statement_end_offset
WHEN -1 THEN datalength(st.TEXT)
ELSE qs.statement_end_offset
END - qs.statement_start_offset
)/2
) + 1
) AS txt
, query_plan
FROM sys.dm_exec_query_stats 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
ORDER BY 1 DESC
第 13 行是
FROM sys.dm_exec_query_stats AS qs
不知道是什么问题
