RECOMPILE / REFRESH UDF?

Dec 19, 2007

Is there a way (command or stored procedure) to RECOMPILE or REFRESH a USER DEFINED FUNCTION? I can recompile SPs with sp_recompile and refresh views with sp_refreshView, but I could not find any way to refresh User-defined functions (some of them are like views, with parameters).

Environment: SQL 2005 SP2.


Thanks !

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?

7.0 Recompile.

Sep 13, 2000

We have lots of stored procedures containing temporary tables. In SQL 6.5 every thing was great. But in 7.0, it's doing a lot of recompile while executing. Tried trace flag 8720, didn't work..

Basically I am talking abt this problem :

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.

Using Recompile On Stored Procedures

Aug 10, 2000

If my data structure never changes, just the data itself, is
there a need to use the "with recompil option" on stored

the stored procedure?

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.

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

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);

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

How To Refresh

Nov 9, 2005

sql2000

I have an existing data warehouse that is refreshed nightly from system1.

We will be moving to a new system2 1/1/06.
The old system1 will be phased out by the end of 2006.
Several tables on system2 will have different keys.

I have to move the data from both systems in the data warehouse.

Here's the issue.
I have to totaly refresh the data warehouse nightly.
Once system2 is phased out how do I keep the data from system1
and refresh only data from system2.

Need Refresh Connection Or Something ?

Jun 23, 2007

HI,
I have a problem with  the data that I want to delete and insert new one on my SQL.It will work if I just delete a row. And work well if I just insert a row.But it will not work if I delete and insert at once on one procedure.
Here's the code :
    Protected Sub RolesRadioButtonList_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles RolesRadioButtonList.SelectedIndexChanged        Session("CurrentRoleId") = Me.RolesRadioButtonList.SelectedValue        ' Call Sub RemoveUsersInRoles        RemoveUsersInRoles()        ' Call Sub AddNewUsersInRoles        AddNewUsersInRoles()    End Sub        Sub RemoveUsersInRoles()        '   Create SQL database connection        Dim sqlConn As New SqlConnection("Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|ASPNETDB.MDF;Integrated Security=True;User Instance=True")        Dim cmd As New SqlCommand        cmd.CommandType = CommandType.Text        '   Delete that row with correct UserId        cmd.CommandText = "DELETE aspnet_UsersInRoles WHERE (UserId = '" & Session("CurrentUserId") & "')"        cmd.Connection = sqlConn        sqlConn.Open()        cmd.ExecuteNonQuery()        '   Close SQL connecton        sqlConn.Close()    End Sub        Sub AddNewUsersInRoles()        '   Create SQL database connection        Dim sqlConn As New SqlConnection("Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|ASPNETDB.MDF;Integrated Security=True;User Instance=True")        sqlConn.Open()        '   Create new row with new UserId        Dim sqlString As String = "INSERT INTO aspnet_UsersInRoles (UserId, RoleId) VALUES( '" & Session("CurrentUserId") & "','" & Session("CurrentRoleId") & "')"        Dim sqlComm As New SqlCommand(sqlString, sqlConn)        Dim sqlExec As Integer = sqlComm.ExecuteNonQuery        '   Close SQL connection        sqlConn.Close()    End Sub-------------------------------------------
I can delete the row if I call 'RemoveUsersInRoles'And I can insert new one if I call 'AddNewUsersInRoles'
But if 'RolesRadioButtonList_SelectedIndexChanged' is called, it will not work well.If the row not exist, it will insert new row. And that what I want.But If the row is exist, It wont delete that row and wont insert the new one. That's the problem.
Do I need some 'pause' or 'refresh connection' here ?
Thank You.

Refresh Issue

Mar 21, 2001

Our application is C++ and datbases are Sybase. We are 11.5.1 Sybase. Lately some of our clients have complained about data refresh problems. That if a user has made some changes within the application then these data changes are taking long time to reflect to other users in the system. We do have in our application processes to automatically refresh data for other users but for some odd reason it is not working properly. Also every day we run sp_recompile and sp_stat on the tables and stored procs. Any ideas or leads ?

How Do I Refresh A View?

Jun 25, 2007

You know how I mentioned before that I was working with a database with a (bunch of) view(s) that are defined like this...

CREATE VIEW MyView AS
SELECT * FROM ExampleTable

Well, after altering the underlying table I noticed that the view is not picking up the new columns which leads me to believe I need to refresh the view.

Is this possible, if so, how?
