如何查看 SQL Server 占用内存

SQL语句本身占用的内存，好象没有吧。SQL语句执行过程的状态，可以使用语句：

SELECT s2.dbid,

s1.sql_handle,

(SELECT TOP 1 SUBSTRING(s2.text,statement_start_offset / 2+1 ,

( (CASE WHEN statement_end_offset = -1

THEN (LEN(CONVERT(nvarchar(max),s2.text)) * 2)

ELSE statement_end_offset END) - statement_start_offset) / 2+1)) AS sql_statement,

execution_count,

plan_generation_num,

last_execution_time,

total_worker_time,

last_worker_time,

min_worker_time,

max_worker_time,

total_physical_reads,

last_physical_reads,

min_physical_reads,

max_physical_reads,

total_logical_writes,

last_logical_writes,

min_logical_writes,

max_logical_writes

FROM sys.dm_exec_query_stats AS s1

CROSS APPLY sys.dm_exec_sql_text(sql_handle) AS s2

WHERE s2.objectid is null

ORDER BY s1.sql_handle, s1.statement_start_offset, s1.statement_end_offset
