Query slower in stored procedure(after upgrade to 16)

Hi all,
We are looking to upgrade our SQL Anywhere 9 database to 16. We thought version 16 is slower in update tables, but the reason of slowness are query's in stored procedures called from the trigger. One of the query's has a duration of 8 times the duration in version 9!! When I run the query in Interactive Sql(v16), they run fast like version 9. So the query runs slower in a stored procedure.
I thought parameter sniffing, but it's not MS Sql Server. I've no idea why it was good in v9 and bad in v16. Have someone a idea?
It's a query with subquery's in the where , a view in the from. In the view are unions. Looks not so special.
thanks

It may be more convenient for you to ask this question on the other forum: SAP SQL Anywhere Forum
Preamble...
It sometimes happens that (a) the same query will perform faster or slower in different versions because of different behaviors by the query optimizer. In most cases a minor change is necessary to restore good performance; in some rare cases, the changes are difficult.
It also sometimes happens that (b) the same query will perform faster or slower under different operating conditions; e.g., client request (ISQL) versus inside a BEGIN block (stored procedure). Again, minor changes all that's required in most cases, sometimes otherwise.
Details...
In order to help, we will need more information. Two graphical plans with statistics for the same problematic query, both using V16, one captured in ISQL, and the other one captured inside the stored procedure, is the best way to pass on the information; ALL OTHER forms are inadequate, especially prose descriptions and edited snippets of code (that way lies frustration for all parties).
There are a number of articles about graphical plans on this blog.

Pages on my iPad3 has become very slow to open documents after upgrading to ios7. I've clicked on a folder 5 minutes ago and am still waiting. The work-around seems to be to force-close it, but I've needed to do this many times in the last few days.

Pages on my iPad3 has become very slow to open documents after upgrading to ios7.
I posted on here about this a few weeks back and someone suggested force-closing Pages -- and that does indeed enable me to open things -- but I have had to force-close many times in the last 24 hours, which is worrying. Are there any other suggestions?
I am sometimes also finding that, when I have been writing something and then click on "documents" the screen goes blank, there is a wait of around a minute and then the same document is re-displayed, before clicking "documents" again lets me look at other documents -- which is a pain if I am trying to move between documents repeatedly. Again, words of wisdom on this would be great.
Pages under iOS6 opened quickly, and there was an immediate loss of performance when I upgraded. I am finding this very frustrating because I don't feel that the new Pages has added to the facilities I was using, but a slowness to open documents is frustrating.
Thanks

This is no string http in your procedure. Then again the error message points to a line 47 outside a stored procedure. I can't tell it is outside, since there is no procedure name.
But I see that you have this piece of dynamic SQL:
SET @sql = ' EXEC msdb.dbo.sp_send_dbmail @profile_name = ''DBA_mail_test''
,@recipients = ''' + isnull(@recipients1,'''') + ''',@subject = ''' + isnull(@mailheader,'''') + ''',
@body = ''' +isnull(@tableHTML,'''')+ ''',
@body_format = ''HTML'''
Exec(@sql)
Why is this dynamic SQL at all? Why not just make plain call to sp_send_dbmail?
EXEC msdb.dbo.sp_send_dbmail @profile_name = 'DBA_mail_test'
,@recipients = @recipients1, @subject = @mailheader, @body = @tableHTML

Can not delete data from table which is queried in my stored procedure

Hi,
Anyone knows how to fix it:
I have a table. In a stored procedure, I have a simple query running on this table.
When I want to delete one record from that table, I got error message:
ORA-04091: table *** is mutating, trigger/function may not see it.
Thanks first.

Rick, the only time you should get a mutating table error is when a trigger is involved. FK problems have separate error codes (and would be a different problem than the one that started this thread). Using a DBA id check all the tables subject to DML by your function and by whatever calls your function for triggers. Only the owner or a DBA can see the existence of triggers on a non-owned table. This has caused some of the developers I work with to think tables that had triggers do not have them since they do not work under the owning or a DBA ID.
By your description of what you are trying to do in the function we do that all the time without problem.
How large is the function? How/When is it called?

Query Timeout on stored procedure executed from Access 2010

I am trying to delete old jobs from a SQL 2008 R2 database. I created a stored procedure on the server that deletes all Jobs over 1 year old. The delete can take several minutes to run as it deletes record on several related tables. I am getting a error
"2147217871 - [Microsoft][ODBC SQL Server Driver]Query timeout expired". The query runs fine on the Server. I have tried setting Client timeout to 300 sec but it times out way before 5 min. I am not sure what else I
can do to fix this problem. I am hoping someone has seen this and figured out a fix.
Here is there code
Public Sub Cleanup_Database()
On Error GoTo CleanUp_Err
    Dim cmd As ADODB.Command
    Set cmd = New ADODB.Command
    ODBC_conn = "ODBC;Description=testbox2;DRIVER=SQL Server;" & _
                "SERVER=O2GMSAPPTEST\SQL122DEVL;Trusted_Connection=Yes;" & _
                "APP=Microsoft Office 2010;DATABASE=IMB_TraceData;StatsLog_On=Yes"
    cmd.ActiveConnection = ODBC_conn
    cmd.CommandType = adCmdStoredProc
    cmd.CommandText = "DataBase_Cleanup"
    cmd.Execute
CleanUp_Err:
    Dim i As Long
    Dim str As String
    str = ""
    For i = 0 To Errors.Count - 1
        str = str & Errors(i).Number & "-" & Errors(i).Description & " " & vbNewLine
    Next i
    If str = "" Then
        str = Err.Number & " - " & Err.Description
    End If
    MsgBox str, , "Trace Update"
End Sub


You didn't say how you were setting the client timeout, but this has worked for me in an adp.
'Temporarily increase query timeout, which is an application-wide setting
'CurrentProject.Connection.CommandTimeout = 60 'Too late to change this setting- no effect
Const cstrTimeoutOptionName As String = "OLE/DDE Timeout (Sec)"
Const clngTimeoutSecondsForQuery As Long = 300
strQueryTimeOutOriginal = Application.GetOption(OptionName:=cstrTimeoutOptionName)
Application.SetOption cstrTimeoutOptionName, CStr(clngTimeoutSecondsForQuery)

SQL query statement for stored procedure / function listing ...

Hi everyone,
Is there a SQL query to list all the stored procedures and functions of an user in an Oracle 8 database?
I have this idea:
select * from USER_SOURCE where TYPE = 'PROCEDURE' or TYPE = 'FUNCTION'
but I am not too sure whether this is correct.
Thanks in advance,
Eric

Yeah
I agree with you Garcia , my above posting was a correction to the query mentioned in the question only.
you are correct
If you only want the name of the object,
SELECT Object_Name from User_Objects where object_type in ( 'PROCEDURE' ,'FUNCTION');
is much faster than Selecting (distinct) from User_Source.

Extremely Slow Time Machine Backup after upgrading to 10.8.3

Time machine backups are taking an extremely long time on my retina MacBook Pro 13 inch after upgrading to 10.8.3. It's taking many minutes just for a kilobyte to be backed up. I've tested transferring something to the disk and it's lightening fast so there's nothing wrong with the disk.
Is anyone having similar issues or know of a fix?

I had the same problem with slow backups. Called Apple 5 times and went through all the hoops checking plists, airport, and then erasing using my airport utility and the first backup of about 25-30 gigs went fine, but the second backup would take between 1-2 hours. By the time it was finished it was ready to do another backup.
After looking at community fixes I found that my Comcast Norton Anti Virus was the problem. Upon speaking for the 6th time to Apple I was told that should have been the first thing they asked, since antivirus programs check each file going to the time capsule. Even unchecking the scan external drives did not help.
I removed the Norton AV from my system and replaced it with the IAV from apple store (free) and my backups are back to normal. I timed a 100 meg using Ethernet/LAN and it took 9 minutes 32 seconds from clicking backup now, searching for backups, preparing backup, backingup, and cleanup. My Wifi connection on 10 megs took only 1 minute 29 seconds.
Now my backups run so fast I don't even see them working. Also the constant updates to Norton were casuing my backups to be 100 megs or more each time due to daily Norton updates. Now I get backups in the order of 10-20 megs - depending up what I have put on the machine. If I put music on it increases the size of the files installed.
I recommend anyone having this slow time capsule problem to turn off your full antivirus program no matter what you are using and watch the difference in speed. I am so happy! No more 2 hour backups and 45 minutes to 1 hour preparing backup! good luck

Parameter in Query manager running stored procedure

Hi Experts!
I have a stored procedure, which is waiting a parameter.
I would like to write a query in sap with parameter using sap language:
exec sp_leltar [%0]
The parameter is numeric, but when running the query above, it is giving an error:"Userdefined errors".
Any idea?Thats not a way to write the parameter value on editor field.

I have tried to run the following:
select from dbo.omaleltfej t0/
declare @leltid numeric OUTPUT
/* where*/
set @leltid = /* t0._leltfejid */ [%0]
exec omaleltareredmeny2 @leltid
Error message:"...Can not use the output option in declare or create function statement..."
I gave up to solve it, because this is not an SAP table, it is not possibble to do.
Thank you for your effort.

Send SQL query or call stored procedure, which is best???

hello experts!!
i would like to ask what will be the best implementation on querying a database using Java, send a SQL query(insert into table values...) or call stored procedure(just pass parameters)?? and also in stored procedure does "autoCommit/rollback" applies/make sense??

I searched google for this:
Stored Procedures vs. SQL
and found this useful link:
http://www.karlkatzke.com/stored-procedures-vs-sql-calls/
I thiink you should also read up on other articles based on such google searches
to get other opinions. Also, read the links provided by that article.
Personnally, I think stored procedures should be avoided unless there is a definite
advantage as specified in the above article. Especially not used for CRUD operations.
Also, no matter where you put the SQL, it should be documented. I've seen too many stored procedures that aren't documented.

Exit stored procedure after UPDATE

Hello,
I have written a LOOP that calls a second Stored Procedure.
In the second Stored Procedure I have 3 INSERTS each SELECT's values limited with a WHERE clause.
Example:
begin
dynsql:=INSERT INTO destinationtable (ID,DATE,NAME)
SELECT src.ID,src.DATE, dest.NAME FROM sourcetable src INNER JOIN destinationtable dest ON dest.ID=src.ID WHERE dest.date between '01.JAN.2012 and '03.JAN.2012' --if not condition not met, no insert
execute immediate dynsql;
dynsql:=UPDATE destinationtable SET DATE = dest.DATE FROM sourcetable src INNER JOIN destinationtable dest ON dest.ID=src.ID WHERE dest.date between '01.JAN.2012 and '03.JAN.2012'
execute immediate dynsql;
dynsql:=INSERT INTO destinationtable (ID,DATE,NAME)
SELECT src.ID,src.DATE, dest.NAME FROM sourcetable src INNER JOIN destinationtable dest ON dest.ID=src.ID WHERE dest.date between '01.APR.2012 and '01.MAY.2012' --if not condition not met, no insert
execute immediate dynsql
dynsql:=UPDATE destinationtable SET DATE = dest.DATE FROM sourcetable src INNER JOIN destinationtable dest ON dest.ID=src.ID WHERE dest.date between '01.APR.2012 and '01.MAY.2012'
execute immediate dynsql;
dynsql:=INSERT INTO destinationtable (ID,DATE,NAME)
SELECT src.ID,src.DATE, dest.NAME FROM sourcetable src INNER JOIN destinationtable dest ON dest.ID=src.ID WHERE dest.date between '01.JUN.2012 and '01.JUL.2012' --if not condition not met, no insert
execute immediate dynsql;
dynsql:=UPDATE destinationtable SET DATE = dest.DATE FROM sourcetable src INNER JOIN destinationtable dest ON dest.ID=src.ID WHERE dest.date between '01.JUN.2012 and '01.JUL.2012'
execute immediate dynsql;
end;
commit;What do I do?
I update the existing "old" row with a new date and then I am basically duplicating that row but adding it with a new DATE, the ID and NAME is "copied" as it is.
The big problem is that the rows result in recursive updates. if the first statement updates a date it might make the conditions for the second and first update become "true".
Which is not what I want. Initially, only one of the statements is true, ever. The problem with my code is that after the first update and date setting, another "might" become true.
This should stop. After one of the updates occured, I need to stop the stored procedure.
How do I stop it after upate?

Hello BlueShadow, that makes sense. Thanks.
Can you tell me when sql&rowcount is reset, after an execute immediate, after a commit?It doesn't get 'reset' in the strict sense. When a PL/SQL program unit is initiated the implicit "SQL" cursor space is defined and exists in the scope of that program unit. At that point it is like any variable that is declared with it's value undefined (null). When you issue any DML statement (insert, update, delete, merge etc.), these will explicitly set the ROWCOUNT attribute within the SQL cursor space. Other SQL statements are also issued from PL/SQL through the SQL "space" (interface), and as such, they may (it's not defined anywhere) effect the values of attributes within it, including the ROWCOUNT, but we cannot say exactly in what way. Therefore, the only thing that can be definitely determined is that a) when it's first instantiated, the SQL%ROWCOUNT will be null, and also, )_immediately_ after any appropriate DML statement the SQL%ROWCOUNT will contain the number of rows effected. If the SQL%ROWCOUNT value is examined at any other point, the value is indeterminate so, for example, after a commit statement, we cannot be sure what value it has or what that value refers to.
I loop through each tax no. need to do either an update, update or delete, delete, each with different WHERE clauses. the danger is that
I update and then the where clause for the deletion becomes true, but my process should not do the deletion if an update happened. its a sequential check and ones true and update/deletion made, the loop stored procedure should terminate. right now I check for sql&rowcount to "not" get into a update or delete if one already happened but I fail to grasp the logic of when sql&rowcount gets which value . I have the feeling that the parent stored procedure that calls my second one with the update and deletes sets the sqlrowcount to 1 because it has an insert. (I use 11g)After your insert/update you should immediately get the value of SQL%ROWCOUNT into a variable, so that you have the value before it is effected by other statements.
You can then use that value in your variable to determine program logic e.g. whether the delete should process or not, regardless of whether you issued further code between the insert/update and the check to see if you should delete. Don't rely on things 'resetting' the ROWCOUNT attribute, only rely on things setting it.

Check Stored Procedures after Migration from MS SQL Server 2008 to Oracle11

I successfully migrated my application database (azteca) from MS SQL Server 2008 to Oracle 11g R2. After migration, I found there are few stored procedures are not valid. How do I check these invalid stored procedures and find what is wrong with them by using SQL Developer? Thanks for your help.

Hi Kevin,
You posted quite a bit today, so perhaps you have already worked this out. If not...
1. View -> Reports -> Data Dictionary Reports -> All Objects -> Invalid Objects [for a specific schema name]
2. Next, for each invalid stored procedure listed in (1)...
a. Open in the code editor from the Connections navigator tree
b. Click on the Compile icon (two gears meshed together) in code editor tool bar.
c. Look in the Compiler log pane for errors.
d. Correct the errorsOf course, success in addressing any errors depends on your skill level dealing with Oracle PL/SQL.
Also, it may be helpful to read over section *3.2 Stored Procedures* in the supplementary migration guide:
http://docs.oracle.com/cd/E35137_01/doc.32/e18462/trig_stored_proc.htm#CHDEIGBC
