Re: SAP hana Visualize Plan show Create Temp Index and it shows Unsupported Operator Order.  Why the hana build temp index and how to get rid of it ?

Wait a minute - BINTONHEX(A.PARTNER_GUID) = B.PARTNER_NO - in your earlier post you wrote that the PARTNER_GUID and PARTNER_NO are of the same data type anyhow.

Upon re-reading I realized that this is not the case.


The conversion has to happen as PARTNER_NO in CRMD_PARTNER is a character data type.

For the database layer there is no way to "know" that both columns essentially store the same information.

 

Would be interesting to hear what the application colleagues can say about this choice of data types.

You may want to consider a character lob data type (CLOB/NCLOB) for your "cell".

Yes, it was my original assumption that they were the same types. However, when I saw this specific error I made the discovery.

 

Since then I am working through a different set of tables to achieve a similar result. Interestingly enough, I am not seeing a huge change in performance either!

OOPS in HANA

Hi Experts,

 

   i am currently planning to use native HANA application to build our new application. When i was thinking of the design of the back end API, i got the following  questions.

 

   1.   is there a way to use Object oriented development in hana, using either  SQLscript or via C++ or R or any other naively supported languages supported by HANA.

 

   2. if the answer for the first question is yes, then is there a way to achieve it without affecting performance or any other cons.

 

 

Thanks,

Karthik.

Dear Karthik,

If you would like to do the development in the ABAP layer and want to make use of the HANA features directly you may want to consider AMDP(ABAP Managed Database Procedures) available since release AS ABAP 7.4 SP5 onwards(only for HANA DB).

The basic idea of AMDPs is to make use of ABAPclasses as the containers for HANA stored procedures. You can find a nice intoruction to AMDP here in this document.

Best regards

SAP HANA is a database technology. If you want to code natively in SAP HANA you have to follow SQL Script or modelling perspectives. You can consume the same artefacts from XSJS context also, Which is basically for web enabled applications. Otherwise, you may need to establish the connectivity with HANA DB from external languages (like java, C++, VB etc) and access it.

 

---SQL Script is procedural language. XSJS supports JavaScript coding standards

Hi sree and sundar, thank you for your response,

 

i understand that HANA is a DB and we have to go with sql script, ..... but when SAP encourages the use of HANA as a platform, i am wondering whether there is a provision in HANA for a complete object oriented development , that would enable something like complete frameworks developed naively  in HANA.

 

i understand that we can use object oriented programming in XSJS using objecting oriented Java Script, but i am so curious to know whether the is any support for OOPS in DB layer as well.....

Convert GUID_X16 to GUID_C22

Hi,

 

There is a function module in SAP, GUID_CONVERT which converts the GUIDs from x16 to c22 and vice-versa. Is there a possibility to put the logic in HANA procedure?

 

We are trying to get MATNR from MATID / MATKEY in EWM. We are using EWM on HANA. There is a function module in SAP, CONVERSION_EXIT_MDLPD_OUTPUT which takes the GUID and returns Material Number. We would like to have the similar logic in HANA model / procedure.

 

Is there any way to achieve this?

 

Thanks,

Aamod

Setting to keep a table from loading into memory?

Anyone know if there a table setting in SP6 to keep a table from being loaded into memory?  As far as we know nothing is querying this table yet we've had to unload it several times recently.  We have stopped replication but we're not ready to remove the table yet, we need to keep the historic data.  Any ideas? 

Thanks!

ODP in SAP HANA

Hi,

 

We are trying to implement ODP to bring data from SAP ECC to Native hana. My guess is we still need SLT to bring data from SAP ECC to SAP HANA. But I am not getting proper documentation on what I should be doing regarding configuration and settings to use ODP with SLT to bring SAP ECC data to SAP HANA.

 

I looked through scn but didnot find any relevant suggestions or answers.

 

Did anyone tried this option?

 

Any suggestion/ideas will be helpful.

 

thanks in advance.

There's no way to prevent tables from being loaded into memory, except dropping them.

With SP6 you don't have access to the LOAD statistics, so it can be a little bit difficult to find out what causes the table to be loaded to memory.

However, why do you feel you need to manually unload it?

If the table is not actually accessed at all (btw: what does make you so sure it's not accessed?) then SAP HANA will remove it from memory, as soon as more free memory is actually required.
