Re: HANA SQL Sub Query - Unique Record

Appreciate your feedback, I was able to resolve it using the MAX function.

Below is my query.

 

Can you suggest a good document.


it_sales_data has the sales order data. My below query works perfect.

SELECT  b.mandt,b.vbeln,b.posnr,b.etenr,b.ettyp,b.edatu,
        b.bmeng as vbep_bmeng,b.vrkme as vbep_vrkme,b.mbdat,
        b.lifsp,b.lddat
        from :it_sales_data as a
        LEFT OUTER JOIN vbep as b on  a.mandt = b.mandt and
                                      a.vbeln = b.vbeln and
                                      a.posnr = b.posnr
       where b.bmeng = (select max(BMENG) from vbep as c where b.vbeln = c.vbeln and
                                                                                                          b.posnr = c.posnr )
       order by b.vbeln,b.posnr;

HEX String to INTEGER conversion

Hi,

 

I would like to convert a hex string representation to the corresponding INTEGER value.

 

I've tried:

 

select cast(hextobin('A') as int) from dummy;

which yields:

 

Could not execute 'select cast(hextobin('A') as int) from dummy' in 34 ms 902 µs .

SAP DBTech JDBC: [339]: invalid number: '0A' at function to_int()

 

I know that the next statement works, but 0xA is already binary and I guess implicite typeconversion just parses the token to integer without typecasting.

 

select cast(0xA as int) from dummy;

Any ideas?

 

Many thanks in advance,

Bodo

 

PS: The background is that I'm searching a way to hash a string value with hash_sha256 to number format (like ORA_HASH in oracle db). I've not found a way to typecast varbinary to number. Instead I try to convert to hex representation first and then convert to integer.

This looks like a core HANA DB question, not Cloud Platform related => moved to HANA dev center.

Passing nvarchar param values to scalar UDF from XSJS

Hi,

 

I've created a few scalar UDFs (User Defined Functions) in HANA repository via an XS project. They work really nice from SAP HANA Studio SQL Console, but despite many attempts I've not managed to pass nvarchar param values from XSJS. Let me show the problem on an example:

 

Capture.PNG

 

This very simplistic scalar UDF is executed without any problems and returns a result at once in SQL Console, however within XSJS I get an error:

 

Capture4.PNG

Capture3.PNG

I have tried with different users and privileges, different functions (scalar UDFs with integer parameters are working fine), .xssqlcc, but without success.

 

Thank you in advance for your help!

Hi,

 

yes i can create a attribute view and preview the data. but in analytical view don't have permissions.

 

i'm wondering in HANA cloud platform why don't have an administrative rights?  now since i'm a user how can i assign privileges which i don't have.

 

how to give permissions to my user id to have other privileges where i can create schema, create tables, load data etc.

 

in short how to assign rights for a user ( who doesn't have rights to assign) in Cloud platform.

any configuration to setup?

Hi,

what's the best way for useing SAP HANA Studio + SAP Development Tools for Eclipse ?


HANA Studio and install new Software form https://tools.hana.ondemand.com

     or

Downloading from SAP Software Download Centers,  https://support.sap.com/swdc
and installing from local disk "SAP BW MODELING TOOLS", "SAP ABAP IN ECLIPSE"


What's that what's in Eclipse Downloads: Kepler or Luna ?


What's that what's in SAP Software Download Centers: Kepler or Luna ?


Can You mix software from SAP Software Download Center's
("SAP BW MODELING TOOLS", "SAP ABAP IN ECLIPSE")

with Software from  https://tools.hana.ondemand.com ?


ThanXs

Is it possible to use ABAP dictionary type for stored procedure variable

Is it possible to utilize a classical ABAP dictionary object type in HANA SQL?

 

In my particular case I am working with an .hdbprocedure and would therein like to declare a table variable of a type already existing in the ABAP-dictionary.  AMDP is not suitable in my case.

 

Is that possible or do I have to also declare the table type as global table types via  CDS(.hdbdd files) for consumption within the SP?

Hi Gurus,

 

I have some table pairs with nearly same structure like the tables below:

 

A_TABLE:

 

A_IDsomething not important
1
2
B

 

B_TABLE:

 

B_IDsomething not important
1
2

 

I would like to filter out what is in NOT in B_TABLE, and union the result with the other pairs.

 

The SQL syntax would be the following:

SELECT DISTINCT a_id, b_id

     FROM A_TABLE AS a

     LEFT OUTER JOIN B_TABLE as b

          ON a.a_id = b.b_id

          WHERE b.b_id IS NULL

(then UNION the other pairs...)

 

My problem is that when I do the join in an attribute view and I use the filter on B_ID then I get the following result

 

A_IDB_ID
1<NULL>
2<NULL>
B<NULL>

 

instead of the expected result:

 

A_IDB_ID
B<NULL>

 

Why?

I know that the above SQL could be used in a scripted view, but I would like to use attribute views and a calculation view to union the pairs....

 

THX for the help!

Table types in ABAP Dictionary are in Application layer. They are not database objects, hence you can not refer it in SQL Script .

Input Parameters in Scripted Calculation Views

November 17, 2014, 9:01 am

Hi All!

 

Why are input parameters restricted in scripted calculation views? I mean the following:

 

1) Mandatory: They must be mandatory.

2) Single Values: No multiple values are possible.

3) Default values

 

1) and 3) are possible with graphical calculation views.

 

My major problem concerns 1): I offer several input parameters but the application does not require that all of them are always provided with input values. In the SQL script I use them in where-conditions of select statements.

 

How can I handle it best, when the value shall not be filled? I already thought about passing a default value like X, if one would like to enter nothing. Then do an if - else branch to decide whether there is an X and if yes write a select statement without that input parameter. This sounds clumsy and does not work anyway.

 

So who has an idea?

 

Thanks,

Ingo

reset_by on hdbsequence artifact

November 17, 2014, 1:10 pm
$

I use sequences to generate keys for my tables.  I am trying to use the reset_by clause in my hdbsequence file. It is my understanding that if you use the reset_by clause, it will reset the sequence using the SQL embedded in the hdbsequence file when the system restarts.  In order to keep my seqeuences in line with the actual data already stored in my ID field(s), I need to make sure that the sequences do not reset to the starting point after a system restart.   It appears that I might have a syntax issue or a permission issue on my SQL used in the hdbsequece reset_by because my sequences are all reset to the start_with number on system restart. 

Here's the code for my hdbsequence file.

 

// Obs_Data_ID sequence
schema="MEDPORTAL";
start_with=200;
reset_by="SELECT IFNULL(MAX(\"ID\"), 0) + 200 FROM \"MEDPORTAL\".\"adsm.data::OBS_DATA\"";
depends_on_table="adsm.data::OBS_DATA";

If I run the clause in the SQL console (SELECT IFNULL(MAX(ID), 0) + 200 FROM "MEDPORTAL"."adsm.data::OBS_DATA";) , I get the 33,565 as the result, 

But if I run the SQL to provide the next number in the sequence (select "MEDPORTAL"."adsm.data::Obs_Data_ID".NEXTVAL from dummy;)  I get 201 as the result, indicating that the sequence has been reset to 200. 

I am running the CAL version of Rev 80 on AWS (1.00.80.00.391861 (NewDB100_REL))

Did I do something wrong in the SQL in the reset_by clause or do I need to grant schema permissions to a user other than the SYSTEM user to get this to work?

Thank you,

Jim Giffin

Maybe you should ask that question in a MS SQL Server development forum.

 

Not sure that MS SQL supports parameters for views - that's rather SAP HANA specific.

Usually you would go and simply put the selection criteria in your WHERE condition.

 

What you can do however is something similar: create a user defined function that returns a table.

 

Anyhow, as said above: better ask someone who knows MS SQL Server development.
