Correction, they are written in T-SQL for Microsoft SQL Server. (Not, as stated “Written for MIcrosoft T-SQL Server”).
However the fact remains that the sys DMV’s are not present in Oracle.
I suggest starting with the v$sqlstats view (in Oracle) and trying to figure out what you need from there.

Hi, I think that your problem is that these queries are written for Microsoft T-SQL Server, so they will be different syntax to PL/SQL.
Oracle doesnt have the same system DMV’s that SQL has, which is probably what your problem is.

hi guys ,
i want to find the queries ran and their time. , who ran it from which program.

the first part is solved by
————-sql 1———-
use master
SELECT
t.TEXT QueryName,
s.execution_count AS ExecutionCount,
s.max_elapsed_time AS MaxElapsedTime,
s.creation_time AS LogCreatedOn
FROM sys.dm_exec_query_stats s
CROSS APPLY sys.dm_exec_sql_text( s.sql_handle ) t
ORDER BY s.max_elapsed_time DESC, ExecutionCount DESC

second part gives database name hostname , program name , nt username and loginname

———–sql 2———-
SELECT DATEDIFF(MINUTE, a.last_batch, GETDATE()) RunningTime,
a.spid, a.blocked, a.waittime, db_name(a.dbid) As dbname,
a.last_batch, a.hostname, a.program_name,
a.nt_username, a.loginame, b.text as sqlstatement
FROM sys.sysprocesses A CROSS APPLY sys.dm_exec_sql_text(a.sql_handle) B
ORDER BY a.last_batch DESC

I need your help to combine query 1 and 2 as i am not familiar with cross apply . please help

Hi Ian,

Just for information, I’m running the DB on our server in 2000 compatability mode also, and found that the way to resolve the issue mentioned, was to run the query against the “master” database, rather than our databases.

Sounds like the comment at the end is missing a – to make it :
SELECT DISTINCT TOP 10
t.TEXT QueryName,
s.execution_count AS ExecutionCount,
s.max_elapsed_time AS MaxElapsedTime,
ISNULL(s.total_elapsed_time / NULLIF(s.execution_count,0), 0) AS AvgElapsedTime,
s.creation_time AS LogCreatedOn,
ISNULL(s.execution_count / NULLIF(DATEDIFF(s, s.creation_time, GETDATE()),0), 0) AS FrequencyPerSec
FROM sys.dm_exec_query_stats s
CROSS APPLY sys.dm_exec_sql_text( s.sql_handle ) t
ORDER BY
s.max_elapsed_time DESC — Maximum elapsed time, in microseconds

What seems to have happened is some autoformatting in windows, replacing — with –

You need to run this against the “master” database. This will prevent the error from happening.

@khan

“I have run the above query but i get the following error.
Msg 102, Level 15, State 1, Line 10
Incorrect syntax near ‘.’.

Can any one pls suggest”

You are running an MS SQL database on a 2005 or 2008 server but the DB in 2000 compatibility mode. Up the compatibility to server 2005 and you’ll fix it.

The view contains one row per query statement within the cached plan, and the lifetime of the rows are tied to the plan itself. When a plan is removed from the cache, the corresponding rows are eliminated from this view.

Pinal,

This helped identifying the query which takes time.

Is there a way to kill the long running procedure? In case SSRS report has executed that procedures?

Thanks,
Sid

For those with the:

Incorrect syntax near ‘.’.

problem… I think this is due to database compatabiltiy mode < 90. Still need to test to confirm, but I think that's my problem.
