Query execution order

Hello,
I'm asking myself a question that i can't find the answer for a while...
Is it possible to define an order when we refresh datas in Power Query ?
Like we can do it with SSIS by matching 2 tables, with Power Query is it possible to indicate that we want
the query 2 to get executed as soon as the query 1 is done ?
Thanks !
Best regard.
Moda.

Adom, I don't think so.
Can you submit this as a feature request in the UI via the Smile Frown button?
Thanks!

Multiple Query Execution Order

Is there any way to dictate the order in which multiple queries run?
Example, I have: Q1 Q2 Q3
They are not linked and there no master query.
Any way to tell Q3 to execute first, then Q1, then Q2?

Hi,
We cannot specify the order of execution of the Queries in the Data Model.
Also it is not recommended to have DML statements like INSERT/UPDATE after the 'AfterParamForm' trigger
My sinsere suggestion for you is to have the procedure (to update rows) invoked in the 'AfterParamForm' trigger. This will avoid dependency between queries in the Data Model
If your requirement doesn't suit this approach, check if you can have data links between the three queries

Order of Query Execution in Workbook

I have a workbook with 3 queries. I have some macro code that moves results around and does formatting. The code is dependent on the order in which the queries are executed. I had assumed that the queries are executed in the order they are listed as data providers.
For most of my users, the workbook works fine. But for some, the queries execute in a different order. Is there some way to force the order of query execution?
Thanks,

TopLink uses a deferred transaction model implemented through its UnitOfWork. This means all changes (creation, modify/ removal) are tracked and during the transaction commit phase we perform these operations ordered based on your referential integrity rules (FK constraints).
If you are using TopLink Essentials (JPA) you have the option to issue flush on your entity-manager after the persist call to force the insert to occur prior to your next read.
In Oracle TopLink the only way to do this is to use a DatabaseSession which offers additional calls controlling the transaction directly as well as support insert/update/remove operations without the UnitOfWork. This approach supports these additional calls because it uses a single connection and does not have a multi-client shared cache. This is much closer to a pure data access style versus the rich multi-client persistence infrastructure most commonly used.

Assure order of query execution in toplink

Hi,
can any one please suggest how to assure the order of query execution in toplink.
at present what is happening is.
suppose if i am having 5 queries, first one is Read and based on that out put of the read query, i need to create record in Database and read one more row from database again and save the record in the Database.
1. Read From Database.
2. Insert into Database.
3.Read From Database.
4.Insert into Database.
order that i want is 1,2,3,4 but toplink excution order is 1,3 and 2,4. that means it is doing all reads first and insertions next.
can any one please let me know, is there a way to set the order of the query execution.
thanks in advance,
regards,
Benarjee Gandhavalli.

Query: Module Execution Order

Hi Experts,
I've a query on the execution order of module execution. Say my requirement is File (with FCC) to File (with FCC) and I need to write a module at both sender and receiver end due to some business requirement. My questions are
1. On the sender side, does sender adapter User defined module gets executed before the sender Standard adapter module? If so, what would be the format of data available to the user defined module (XML data after file content conversion) ??
2. Similar query, but for the receiver channel (receiver adapter modules execution order).
Please explain the nature and order of execution of the adapter modules and the format of data available to the User Defined Modules.
Thanks,
Hussain.

Hi Hussain,
So, does that mean the input data to sender custom module is of Text format ie. the whole text file in text format (not in XML format) ? - Yes
Also, can the order of the modules be changed i.e Can custom module be specified and executed later Standard module?? I suppose No but still wanted a confirmation. - Only in synch communication, when you have sender comm channel, there if you have a reciver custom module, then in sender comm channel in module tab, it will be specified after standard module..............But for asnych communication, where you will have a reicever comm channel, there you will specify your custom module before standard module.
Hi Prateek,
I think that the input to the custom module would be xml created after content conversion. - No, the file will be input as plain text file and in your custom module you will create a XML document for your sender msg.........Similar is the case when you have a excelsheet file as input, in it you have your excel file data as input and you create a XML document in your custom module.

Slow query execution time

Hi,
I have a query which fetches around 100 records from a table which has approximately 30 million records. Unfortunately, I have to use the same table and can't go ahead with a new table.
The query executes within a second from RapidSQL. The problem I'm facing is it takes more than 10 minutes when I run it through the Java application. It doesn't throw any exceptions, it executes properly.
The query:
SELECT aaa, bbb, SUM(ccc), SUM(ddd), etc
FROM MyTable
WHERE SomeDate= date_entered_by_user AND SomeString IN ("aaa","bbb")
GROUP BY aaa,bbbI have an existing clustered index on SomeDate and SomeString fields.
To check I replaced the where clause with
WHERE SomeDate= date_entered_by_user AND SomeString = "aaa"No improvements.
What could be the problem?
Thank you,
Lobo

It's hard for me to see how a stored proc will address this problem. I don't think it changes anything. Can you explain? The problem is slow query execution time. One way to speed up the execution time inside the RDBMS is to streamline the internal operations inside the interpreter.
When the engine receives a command to execute a SQL statement, it does a few things before actually executing the statement. These things take time. First, it checks to make sure there are no syntax errors in the SQL statement. Second, it checks to make sure all of the tables, columns and relationships "are in order." Third, it formulates an execution plan. This last step takes the most time out of the three. But, they all take time. The speed of these processes may vary from product to product.
When you create a stored procedure in a RDBMS, the processes above occur when you create the procedure. Most importantly, once an execution plan is created it is stored and reused whenever the stored procedure is ran. So, whenever an application calls the stored procedure, the execution plan has already been created. The engine does not have to anaylze the SELECT|INSERT|UPDATE|DELETE statements and create the plan (over and over again).
The stored execution plan will enable the engine to execute the query faster.

How can I reduce BEx Query execution time

Hi,
I have a question regarding query execution time in BEx.
I have a query that takes 45 mins to 1 hour to execute in BEx analyser. This query is run on a daily basis and hence I am keen to reduce the execution time. Are there any programs or function modules that can help in reducing query execution time?
Thanks and Regards!

Hi Sriprakash,
1.Check if your cube is performance tuned: in the manage cube from RSA1 / performance tab: check if all indexes and statistics are green. Aggregate IDx should as well be.
2.Condense your cubes regularly
3. Evaluate the creation of an aggregate with all characteristic used in the query (RSDDV).
4.Evaluate the creation of a "change run aggregate": based on a standalone NavAttr (without its basic char in the aggr.) but pay attention to the consequent change run when loading master data.
5. Partition (physically) your cubes systematically when possible (RSDCUBE, menu, partitioning)
6. Consider logical partitioning (by year or comp_code or ...) and make use of multiproviders in order to keep targets not too big...
7.Consider creating secondary indexes when reporting on ODS (RSDODS)
8.Check if the query runtime is due the master data read or the infoprovider itself, or the OLAP processor and/or any other cause in tx ST03N
9.Consider improving your master reads by creating customized IDX (BITMAP if possible and depending on your data) on master data table and/or attribute SIDs when using NAvs.
10.Check that your basis team did a good job and have applied the proper DB parameters
11.Last but not least: fine tune your datamodel precisely.
hope this will give you an idea.
Cheers
Sunil

30EA4 Problem using MySql: "Query execution was interrupted"

Any query executes the first time but a second execution always causes the error "Query execution was interrupted"
(Update: I just installed the prodcution release of sql delveloper 2.1.1.64.45 and have the same issue)
I am using MySql driver 5.1.15
Others seem to have a similar issue and I tries the older JDBC drivers but the 5.0.4 cause the connection to hang and the 5.0.8 caused the same problem "Query execution was interrupted"
Vendor Code 1317 Query execution was interrupted MySQL
I am using Windows7 64 bit (sql developer and jdk are 32 bit), see below

Hi Dermot,
Some clarification.
I have tried these 3 drivers below with the following results:
5.0.4 First Query succeeds, Second gives error "Unknown prepared statement handler (131072) given to mysqld_stmt_execute". At this point I can exit SQL Developer. If I run it a third time then the query does not complete and any attempt to exit SQL Developer results in "Connection is currently busy, try again?" and ultimately I have to kill it.
5.0.8 First Query succeeds, Second Query fails with Query execution was interrupted. Subsequent queries give the same result.
5.1.15 Same as 5.0.8
I tried your suggestion, removed the driver, restarted, installed the 5.0.4 driver and restated and ran the test,
(I added a drop table so I could run it repeatedly) and it works repeatedly if I choose "Run as script F5".
DROP TABLE table1;
CREATE TABLE table1(col1 int);
INSERT INTO Table1 values(1);
SELECT * FROM table1;
SELECT * FROM table1;
But If I execute the query "select * from table1" using "Run Statement Ctrl-Enter" twice then I get problem behaviour as described above.
I looked in the logfile for SQLDeveloper but it was empty.
I also tried creating a new database as root and connecting as root (same result)
I also tried the NightlyBuild of 5.1 and 6.0 but gave the same result as 5.1.5.
I have two other tools for accessing MySql: Toad and MySql workbench, both of which work but I've used SQL Developer with Oracle for some years and would like to keep using it.
I just tried connecting to a remote MySQL database and that seems to work without problems.
I'm thinking it may be related to some incompatibility between SQLDeveloper and the MySQL installed locally.
I'll try another version....
Ok I installed a 32 bit version of MySql 5.5.10. I thought things were working but now I still get the problem but it is much more intermittent.
Now I can get it by modifying the query ie.
select * from table1; (works repeatedly untill followed by a change to the query)
select * from table1 order by col1; (fails)
Another case
select * from table1 order by col1; (works repeatedly)
select * from table1 order by col1 asc; (fails first time)
very weird...

Analyzer Query Execution vs. APD Query Execution

hi gurus,
i have a problem with an execution of a query in BI 7.0. the query is based on a DSO.
if i execute the query in bex analyzer, i get the result within 30 seconds.
but if i execute the query in an APD, it will take several hours to complete the job.
i checked the RSRT to view the query execution plan - here it is:
SELECT "O1"."COMP_CODE" AS "K____240" ,"O1"."RECONTRACT" AS "K____301" ,"O1"."FISCVARNT" AS "K____181"
,"O1"."/BIC/ZIMIMNPER" AS "K____535" ,"O1"."BUSENTITY" AS "K____237" ,"O1"."/BIC/ZIMIMGEBL" AS "K____1098"
, COUNT( * ) AS "Z____131" , SUM ( "O1"."/BIC/ZIMIK_113" ) AS "Z____1886" ,
SUM ( "O1"."/BIC/ZIMIK_183" ) AS "Z____1908" , SUM ( "O1"."/BIC/ZIMIK_201" ) AS "Z____1998"
FROM "/BIC/AZIMODSSM00" "O1"
WHERE
( ( ( ( "O1"."/BIC/ZIMIMNPER" = '2010009'
) ) AND ( ( "O1"."/BIC/ZIMIMZBR" IN ( 'BEQ' ,'REFX3' ,'REFX4' ,'REFX6') ) ) ) )
GROUP BY "O1"."COMP_CODE" ,"O1"."RECONTRACT" ,"O1"."FISCVARNT" ,
"O1"."/BIC/ZIMIMNPER" ,"O1"."BUSENTITY" ,"O1"."/BIC/ZIMIMGEBL"
but when i check the SQL statement for the APD in SM51, i found this statement:
SELECT   "S0000"."SID" ,"P0000"."COMP_CODE" ,"P0000"."BUSENTITY"
FROM   "/BI0/PBUSENTITY" "P0000" JOIN "/BI0/SBUSENTITY" "S0000" ON "P0000" . "BUSENTITY" = "S0000" . "BUSENTITY" AND "P0000" . "COMP_CODE" = "S0000" . "COMP_CODE"
WHERE   "P0000"."OBJVERS" = 'A' AND "S0000"."SID" IN ( SELECT "S"."SID" FROM "/BIC/AZIMODSSM00" "O" JOIN
"/BI0/SBUSENTITY" "S" ON "O" . "BUSENTITY" = "S" . "BUSENTITY" AND "O" . "COMP_CODE" = "S" .
"COMP_CODE" )
ORDER BY
"COMP_CODE" ASC , "BUSENTITY" ASC#
could you help me understanding the difference and the cause for it?
i think, there are some validitycheckings executed for masterdata!? is it possible to disable these steps?
here some more information:
in the query, i'm using two compound characteristics and an constant selection for a restricted keyfigure. the characteristics all have access type for result values: posted values.

philipp

Hello,
Check this note:
Note 751577 - APD-FAQ: Data source query
This note helps with the following problems:
Question 1: Query execution terminates or takes too long. What can I do?
Question 2: The data in the analysis process does not correspond with the data in the Business Explorer. What is the cause of this?
Question 3: When you execute the analysis process, the system issues error message B1 888: "For the ISO code &1 there is no unique SAP currency code for ALE". What does this mean?
Question 4: When you execute the analysis process, the system issues error message RSAN_WB 010 (CX_RSAN_SVC_CHECK_ANALYSIS_N=>NODE_FIELDNAME_NOT_UNQIUE). What does this mean?

Jorge Diogo

Query execution Flow

Dear Experts,
I would like to know how does the query execution happens @ runtime.
Definitely its a SQL which been executed in backend.
I have one scenerio Like Cube is having Material As Characteristic (M1,M2,M3)
& Navigation Attribute Material group (MG) also some kef Figure Like Sales-Values.
So can you please let me know what will be the order of tables which will be
referred @ runtime when I execute the query.
Please Advice.
Regards,
Vivek

Hi,
Check in RSRT with execute+debug and select SQL display, you will find the information.

Execution order - group by and order by

is there any execution order when we use group by and order by together in single query ?

BOL: "Logical Processing Order of the SELECT statement
The following steps show the logical processing order, or binding order, for a SELECT statement. This order determines when the objects defined in one step are made available to the clauses in subsequent steps. For example, if the query processor can bind to
(access) the tables or views defined in the FROM clause, these objects and their columns are made available to all subsequent steps. Conversely, because the SELECT clause is step 8, any column aliases or derived columns defined in that clause cannot be referenced
by preceding clauses. However, they can be referenced by subsequent clauses such as the ORDER BY clause. Note that the actual physical execution of the statement is determined by the query processor and the order may vary from this list.
1. FROM
2. ON
3. JOIN
4. WHERE
5. GROUP BY
6. WITH CUBE or WITH ROLLUP
7. HAVING
8. SELECT
9. DISTINCT
10. ORDER BY
11. TOP"

Issue while query execution on web analyser.

Hi,
I am getting an error message while query execution on web ie Record set too large , data retrieval restricted by configuration .I am able to run the same query in bex analyser without any issue .Any idea what could be the reason and solution for this issue .
Regards,
Neetika.

Hi Neetika,
The Query is exceeding the set limits,i suggest you to Reduce the time LIne for the Query, as it may be having more number of Cells in terms of Rows and Columns.
Execute the Query for Less number of Days,if u r executing it for 1 Month then execute it for 10 Days.

SSRS Error : Query execution failed for dataset 'dataSet'. (rsErrorExecutingCommand) Semantic query execution failed. Invalid object name 'RPT.*********'. (rsSemanticQueryEngineError)

I am new to SSRS and I am trying to migrate reports from 2008 to 2012. As I have so many reports to migrate, I simply got the back up of ReportServer,
ReportServerTempDB, and Encryption Key and restored them to test environment. I made necessary configuration from RS configuration tool. I am able to see the reports now when I browse //hostname/reports. But when I open any particular report I am getting some
error.
· An error has occurred during report processing.
(rsProcessingAborted)
Query execution       failed for dataset 'dataSet'.
      (rsErrorExecutingCommand
Semantic query        execution failed. Invalid object name
       'RPT. ******'. (rsSemanticQueryEngineError)
****** - I am assuming this is a custom data class.
Does anyone have insight on this? or any better way that I can migrate the reports to new server with less efforts.
I don’t have the reports solution file to deploy the reports, so I have followed backup and restore process.

Hi Kishore237,
According to your description, you migrated some reports from Reporting Services (SSRS) 2008 to 2012. Now you get error when accessing the reports on SSRS 2012. Right?
In this scenario, did you modify the report data source in database after migration? You can try to open the report in Report Builder or Report designer and check the report dataset. If you can preview the report in Report builder or Report designer,
please try to redeploy the report to Report Server. If it is still not working, please try to restore the database from backup. And for migrating reports, please follow the "Content-Only Migration" in the link below:
http://msdn.microsoft.com/en-us/library/ms143724(v=sql.110).aspx
If you have any question, please feel free to ask.
Best Regards,

Asset query execution performance after upgrade from 4.6C to ECC 6.0+EHP4

Hi,guys
I am encounted a weird problems about asset query execution performance after upgrade to ECC 6.0.
Our client had migrated sap system from 4.6c to ECC 6.0. We test all transaction code and related stand report and query.
Everything is working normally except this asset depreciation query report. It is created based on ANLP, ANLZ, ANLA, ANLB, ANLC table; there is also some ABAP code for additional field.
This report execution costed about 6 minutes in 4.6C system; however it will take 25 minutes in ECC 6.0 with same selection parameter.
At first, I am trying to find some difference in table index ,structure between 4.6c and ECC 6.0,but there is no difference about it.
i am wondering why the other query reports is running normally but only this report running with too long time execution dump messages even though we do not make any changes for it.
your reply is very appreciated
Regards
Brian

Thanks for your replies.
I check these notes, unfortunately it is different our situation.
Our situation is all standard asset report and query (sq01) is running normally except this query report.
I executed se30 for this query (SQ01) at both 4.6C and ECC 6.0.
I find there is some difference in select sequence logic even though same query without any changes.
I list there for your reference.

But it changed to first select ANLA,and open cursor ANLP,then select ANLC,ANLB,ANLZ,at last fetch ANLP.
Probably,it is the real reason why it is running long time in ECC 6.0.
Is there any changes for query selcection logic(table join function) in ECC 6.0.
