No Recompile After Sp_recompile Or WITH RECOMPILE Option

Aug 30, 2007

I know that all the documentation always tells you that sp_recompile will force a stored procedure to recompile the next time it is executed. However, I am not seeing the recompiles in a SQL Trace, when capturing SP: Recompile events. I have tried this on many different database servers, using sp_recompile and also the WITH RECOMPILE option when creating the proc.

Can anyone explain this?

OPTION(RECOMPILE) And Execution Plan

Jan 23, 2008



Hi,


I use recompile option in SQL query to dynamic pass variable to optimizer.

I verify explain plan with SET STATISTICS PROFILE ON

and optimizer chose nested lookup ,ok. But if use Display Estimated Execution Plan (CTR+L) I€™ve get merge join. It€™s very confusing, some suggestion €¦?


Use AdventureWorks

go

declare @StartOrderDate datetime

set @StartOrderDate = '20040731'

SELECT * FROM Sales.SalesOrderHeader h, Sales.SalesOrderDetail d

WHERE h.SalesOrderID = d.SalesOrderId

AND h.OrderDate >= @StartOrderDate

OPTION(RECOMPILE);

Apr 27, 2008

Hi everyone In my SqlServer Management Studio Express, on start up it shows the server type option, but greyed.So that value is fixed to database engine. ( I'm trying to work on an SqlServer Compact Edition database through the SSMStudiothat's why I'm trying to get this to change.)Besides, after I connect i go to the Object Explorer, expand the server node, and go to Replication.When i expand replication, i get the "Local Subscription" option, but nothng for Publication.( I want to work on Merge Replication, that's why I desparately need Publication to work)Am i missing something here? I did not install SqlServer separately, I only have what comes bundled with the Visual Studio  2005 Setup.

EXECUTE… WITH RECOMPILE

Jun 2, 2002

What exactly does WITH RECOMPILE do? I read that it will create a new plan. I guess the next question is, what is the purpose behind that?

Can someone explain to me?

Reload Or Recompile

Oct 30, 2000

Does someone know whether it is better to drop and reload or sp_recompile a stored procedure to get a new, recompiled execution plan? I have another DBA telling me it is better to drop and reload the stored procedure rather than use sp_recompile. I would think that sp_recompile would be the preferred method.

Performance Question: Recompile

Dec 29, 1999

What's the performance hit for using 'WITH RECOMPILE' in a stored procedure? I'm not a serious DBA, nor do I pretend to be one, but I'm writing a sp_ to be used with both insert and updates. I'm using a variable that defines the operation (IF @operation = 'Update'...) which will be passed at run-time from ColdFusion. Do I need to use the 'WITH RECOMPILE' clause to keep the sp_ kosher with respect to the operation being performed? And what's the damage in resources?

Thanks,

John E.

SQL 2012 :: Configuring Memory Per Query Option And Index Create Memory Option

Feb 10, 2015

So I started a new job recently and have noticed a few strange configurations. Typically I would never mess with min memory per query option and index create memory option configuration because i just haven't seen any need to. My typical thought is that if it isn't broke... They have been modified on every single server in my environment.

From Books Online:
• This option is an advanced option and should be changed only by an experienced database administrator or certified SQL Server technician.
• The index create memory option is self-configuring and usually works without requiring adjustment. However, if you experience difficulties creating indexes, consider increasing the value of this option from its run value.

Recompile Of Stored Procedures - URGENT

Apr 11, 2001

We are developing a production/management solution for the photo finishing sector. We need a performance of 1 order priced per second.
If we run the procedure once we dont have a dramatical performance loss due to recompilation of the stored procs.
If we have about 3 consecutive sessions we find the performance loss to be at a rate of about 200 - 500 %.
We can't afford this. On the site of msdn we found some reasons why sql server needs to recompile, but since the structure of our db can't be changed in such a manner that this would resolve the problem we need an alternative.
All help is greatly appriciated.

Stored Procedure Timing Out Until Recompile

May 17, 2007

Hey all,

We have a problem with one of our MS SQL 2000 databases and some stored procedures.

I'm not sure exactly what the problem is, but these are the symptons....

The stored procedure runs without problems for a period of time. Abruptly, without warning it begins to time out when called from our web application.

Calling it through the query analyzer it runs within a second.

Forcing the stored procedure to recompile allows the web application to start calling it again without it timing out.

We have a DTS package that runs over night and imports a number of records (not sure on the exact numbers, but definately enough to make a difference to indexes) so this could be part of the problem although when I force a recompile I do not do any update stats or anything else.

I wrote a test script to call the stored procedure when it was timing out to ensure it wasn't a web application problem and the procedure continued to time out until the forced recompile. So I don't think the problem is there.

The stored procedure returns multiple results sets and when it starts timing out it is while it is returning the second results sets.

The code for the second results set is...


Select avg(round(p.PricingValue, 5)) as Average, stdev(round(p.PricingValue, 5)) as StdDev, min(p.CaptureDate) as FromDate, max(p.CaptureDate) as ToDate
From Pricing p
Inner Join Security s
On p.SecurityID = s.SecurityID
Left Outer Join Issuer i
On s.IssuerID = i.IssuerID
WHERE p.PricingTypeID = @PricingType
And p.TenorTypeID = @TenorType
And p.CaptureDate Between @DateFrom And @DateTo
AND p.SecurityID IN ( SELECT SecurityId FROM UserResult ur WHERE ur.UserResultSelected = 1 AND ur.UserID = @userID )


Does anyone have any idea what might be going on here?

Regards
Shaun

Can We Recompile View Instead Of Drop And Create

Jan 31, 2008

Hi,
I increased one of my base tables column which is referenced in view

I noticed sql server didn't recognized this change and its still showing old field size in the view.

I can simply drop and create it again. But wanted to know if there is any way (command/sp) to recompile the view which will be easy to deploy in production as patch.

Thanks

How To Force Immediate Recompile Of Triggers And Detect Errors?

Mar 23, 2006

I need a way to programmatically (via JDBC) find out which triggers for a table may not compile properly, so that I can disable the bad triggers.

I can do this fine in Oracle but cannot figure out if there's a way to do this in SqlServer. (In Oracle I'd just "alter trigger... compile" and select from user_errors.)

I know how to find the triggers that exist on a table, and I know how to enable/disable individual triggers. I know about sp_recompile, but all that does is flag the trigger for recompile at the next execution.

I need to verify whether the trigger is valid without having to actually invoke it. For example, if there's a bad Update trigger, I don't want to actually execute an update on the table.

One example of what I'm dealing with is this... We have Table A and Table B. There is an update trigger on Table B that references column A.col1. Then we alter Table A to drop col1. Later we have to update Table B. At this point the update will fail because of the bad trigger. I want to find and disable the trigger before executing the update on Table B. If there are other triggers on Table B that are valid, I want to leave them alone.

Views Containing SELECT * Do Not Recompile When Table Is Modified

Mar 17, 2008

If I have a view such as: SELECT T.* FROM T
When I add a column to table T the view is not updated to reflect that change.
Furthermore, if there are other columns after the * in the view (for example SELECT T.*, GETDATE() as "My Date" FROM T) the last columns will contain incorrect data.

Is there a work around for this? An "auto-recompile when tables are modified" kind of option?

Thanks
Nick

PS: This is the script I used for testing:

create table tt (
test1 int primary key,
test2 int)
go
insert into tt (test1, test2) values (1,2)
go
create view vw_tt as select *, getdate() as "My Date" from tt
go
select * from vw_tt
go
create view vw_tt2 as select * from tt
go
alter table tt add test3 int
go
select * from vw_tt
select * from vw_tt2
select * from tt
drop table tt
drop view vw_tt
drop view vw_tt2

Stored Procedure Doesn't Recompile After Replication Updates Underlying Tables

Mar 21, 2007

We have on demand snapshot replication set up between 2 servers. When the subscriber applies the snapshot, our stored procedures start executing very slowly. Updating statistics and rebuilding indexes does not resolve the problem, however; executing sp_recompile on the affected stored procedures does fix the problem. Is this a known issue with replication? Is there a better workaround than manually recompiling stored procedures after every snapshot?

SSIS Warnings On Build 3159: Precompiled Script Failed To Load. Attempting To Recompile.

Aug 20, 2007

All:

I've implemented a variation of the Custom Logging provided in this post by Jamie Thomson.


http://blogs.conchango.com/jamiethomson/archive/2005/06/11/SSIS_3A00_-Custom-Logging-Using-Event-Handlers.aspx

Everything seems to work well on my desktop during development, but when I deployed the packages to our DEV environment the packages still execute, but I'm now receiving warning messages in the sysdtslog90 log table...

Precompiled script failed to load. Attempting to recompile. For more information, see the Microsoft Knowledge Base article, KB931846 (http://go.microsoft.com/fwlink/?LinkId=81885).


My log table (SSISLog) looks OK, with only OnPostExecute messages that include the package / task information and rowcounts.


The KB article suggests upgrading to SP2, but I'm well past SP2, using Build 3159 on both machines.

Any suggestions on how to get rid of the warnings?

Thanks!
Leda

Force SQL Server To Recompile Stored Procedures Every Time They Run (SQL Server 7/2000)

Apr 27, 2005

This is a solution for a very specific problem, and it's one that you'll hardly ever use, but it's important to know about that one scenario where it can save your neck. Ordinarily, stored procedures are only recompiled if they're no longer in the procedure cache. But if a stored procedure's execution plan is still in the cache, then SQL Server reuses the compiled storedprocedure and its existing execution plan. This is almost always the best course of action. Almost always, but not always.Sometimes, however, reusing an existing plan doesn't offer the most efficient performance. Imagine, for example, that your stored procedure accepts a parameter that determines the natureof a JOIN operation. The results can vary in a big way, so you wouldn't want your procedure to be locked into an execution plan that might be completely inappropriate for that JOIN. In a highlyspecialized case like this, you might want to force SQL Server to recompile the procedure every time the procedure runs. Doing so comes at a performance cost, but this might be offset by thesavings you gain in not executing the procedure with an awful compiled execution plan. Consider carefully whether to use this approach (or whether to re-engineer the over-design of yourapplication to avoid this situation in the first place). Should you need to instruct SQL Server to recompile each time, add the WITH RECOMPILE directive to the procedure, like this:    CREATE PROCEDURE ProcName        @Param int /* ... other parameters */        WITH RECOMPILE    AS /* ... procedure code follows */
If we omit "WITH RECOMPILE", what will be the consequence? Thanks

Recompile SQL Task With Data Flow Task

Feb 23, 2007

Hi,


I created a package with SQL 2005. The package gets the Access DB and then inserts it into SQL Server.

If I open the package in .NET, I can see the SQL Task and Data Flow Task. The SQL Task has a property sqlstatementsource, which has the necxessary SQL code to create the tables.

How can I tell the SQL Task to recompile the SQL code if I give it another DB name, because the tables differ and don't map in the Data Flow Task


Thanks

Which Would Be The Best Option?

Apr 28, 2008

I have a table name “StringResources� which contains resources for different cultures. Right now, whenever admin adds any new resource, it immediately available to end user. Now the new requirement came up. We want admin to add resource first and when he is ready with all the resources for particular culture then only the resources should be available to end user.
Important: StringResource table has SQLCacheDependecy set. So any change for particular culture will invalidate the cache. This how the select statement looks.SELECT dbo.StringResources.resourceType,            dbo.StringResources.cultureCode,            dbo.StringResources.resourceKey,             dbo.StringResources.resourceValue       FROM dbo.StringResources
      WHERE dbo.StringResources.cultureCode=@cultureCode
Which would be the best option below:
1>     Add new Boolean column “Publishedâ€? and show only resources which are published to end user.
Advantage:  No need of extra table.
Disadvantage: This will invalidate the cache every time resource is added even if it’s not published. 
Other option
2>     Add new temporary table with same structure. When admin add new resource, add it to this temp table and when publish move resources to String Resources table.
Advantage: Admin will have separate working space.  It will invalidate cache only when resources are published.
Disadvantage: Need extra table.
