Oracle column store db

I've heard that Oracle 12c will have a column store options similar to what companies like Vertica and SAP Hana have. In a very general question, is this available in the current Oracle 12c release? If so, is anyone using this feature and what is your opinion on the performance side for analytics, such as rapid slicing and dicing of the data.

Hi,
I think you may be referring to the new 'In Memory' option for 12c where oracle will store the data in memory in both 'normal' and columnar format to help with analytics queries (and general performance). This is the thing Larry referred to as 'ungodly speed'.
This should be coming in 12.1.0.2 from what I heard which based on the normal release schedule is probably Q3 this year.
Not sure if it will be a cost option or not but i would guess it will be.

Save HTML data in a Oracle Column

what would be the best way to Save HTML data in a Oracle Column?
while varchar2 can be used for upto 4000 bytes. it would still mean escaping a lot of special character. Is there a better way to do this? any help would be greatly appreciated.

Besides the XML types available to you and the associated Oracle provided packages to input and extract XML I have heard arguments that both should be stored in the database. That is you should store the extracted data in normal Oracle columns so it can be used like any other attribute and that you should store the XML as XML which can then be used as XML.
For data that is only inserted and deleted I can see this method but if updates to information within the XML is required then you just added another set of work requirements and complexity.
Who is going to access the data? What tools are the users going to use? Where else does the data need to be provied to and in what format? The answers to who and how the data will be used should provide you with the answer of what form the data should be stored in.
My personal view is that a relational database should be used for what it was designed for, storing relational data.

While defining a columnar table, what is the purpose of column store type

Hi folks
I have two questions related to columnar table definition.
1. What is the purpose of column store type.
While defining a columnar table, what is the purpose of column store type (STRING ,CS_FIXEDSTRING,CS_INT etc) , when I define a table using the UI I see that the column is showing STRING but when I goto EXPORT SQL it does not show. Is this mandatory or optional ?
2.VARCHAR Vs. CHAR - In the UI when I create the table I do not see the CHAR option , but I do see lot of discussion where people are using CHAR for defining the columnar table. Not sure why UI dropdown does not show it. I also read that we should avoid using VARCHAR as those columns are not compressed, is that true, I thought the column store gives compression for all the columns. Are there certain columns which cannot be compressed .
Please let me know where I can find more information about these two questions.
Poonam

Hi Poonam
the CS_-data types are the data types that are used internally in the column store. They can be supplied but it is not at all required or recommended to do so.
SAP HANA will automatically use the correct CS_-data type for every SQL data type in your table definitions.
To be very clear about this: don't use the CS_-data types directly. Just stick to the SQL data types.
Concerning VARCHAR vs CHAR: fixed character data types are not supported anymore and don't show up anymore in the documentation.
I have no idea why you believe that VARCHAR columns are not compressed but this is just a myth.
create column table charcompr (fchar char(20), vchar varchar(20));
insert into charcompr (
    select lpad ('x', to_int (rand()*20), 'y'), null from objects cross join objects);
-- same data into both columns
update charcompr set vchar = fchar;
-- perform the delta merge and force a compression optimization
merge delta of charcompr;
update charcompr with parameters ('OPTIMIZE_COMPRESSION' ='FORCE');
-- check the memory requirements
select COLUMN_NAME, MEMORY_SIZE_IN_TOTAL, UNCOMPRESSED_SIZE, COUNT, DISTINCT_COUNT, COMPRESSION_TYPE
from m_cs_columns where table_name ='CHARCOMPR'
COLUMN_NAME    MEMORY_SIZE_IN_TOTAL    UNCOMPRESSED_SIZE   COUNT   DISTINCT_COUNT COMPRESSION_TYPE
FCHAR       3661                    70285738            6692569 20              RLE
VCHAR       3661                    70285738            6692569 20              RLE
We see: compression and memory requirements are the same for both fixed and variable character sizes.

SAP HANA XSODATA service (Service exception: column store error.)

Hi all,
i have a problem with my calculation view using xsodata service on it. (There's an input parameter called P
_SWERK)
In my calculation view, the data origin are two analytic views (on which the input parameter P_SWERK should be filter data at beginning of the sql script code).
First i read the analytic views with function CE_OLAP_VIEW and after i do a CE_PROJECTION function on them using the input parameter P_SWERK like a filter on field SWERK.
But when i run my application on browser the following error occurs :
<message xml:lang="en-US">Service exception: column store error.</message>
The link is this :
http://host:port/Project_DM/services/Test/TEST_ZIIG_PDM_CALC_VIEW_FINAL_service.xsodata/PianiDiManutenzioneParameters(P_SWERK='CO05')/Results
The service definition is :
service {
"EricssonItalgas/TEST_ZIIG_PDM_VIEW_FINAL.calculationview" as "PianiDiManutenzione" keys generate local "ID"
parameters via entity;
The SAP HANA AWS revision is 60.
Someone could you help me,please?
Thanks in advance.
Dario.

Hi Dario,
Does the calculation view work without xsodata service? From the URL, your XS project name should be Project_DM, but from the xsodata source, the project name is EricssonItalgas. I'm confused with this. Did you use rewrite_rules or?

Error in running a query in XSJS - column store error: [2950] user is not authorized : at ptime/session/dist/RemoteQueryExecution.cc:1354]

Hi All,
I get the below error when i load my xsjs file in browser,
Error while executing query: [dberror(PreparedStatement.executeQuery): 2048 - column store error: column store error: [2950] user is not authorized : at ptime/session/dist/RemoteQueryExecution.cc:1354]
I am able to execute the same query in HANA SQL editor
Please note that ,No Analytical privileges are applied to the view.
Could you please help solving this issue.

Hay,
are you using the same Database user for both SQL Editor and XSJS ?
try the following.
Before executing the query , display it and copy the same from browser and execute in SQL editor.
Put the statement in a try catch block and analyse the exception .

Column store errors during runtime

Hi,
I created a HANA instance in the trial landscape and directed my application to use the HANA instance schema. Over time, I get errors:
SAP DBTech JDBC: [2048]: column store error: search table error: [29] attribute not defined for physical index;internal error: attribute 'NEO_29J91OPIP2IAEWXFUZRHT093R:CA_EV_VENUEen/PK_EVENT_VENUE_ID' not found in indexInfoMap
I'm using the HANA instance instead of the default schema created from the application because I need to run spatial queries, which is currently only available in the HANA instance.
Does anyone know what's wrong?

Additional errors from the HCP logs:

The table CA_EV_VENUE contains spatial column and only this table is "failing". Other tables doesn't contain spatial columns are fine.

Converting column store to row store

Hello Everyone,
I have a question related to the Column store to Row Store conversion:
Is it always necessary to perform the conversion when all connections to the system have been stopped from the application level?
what would be the loss if the conversion is performed with the applications or connections to the system still open?
Regards,
Vinay

Hi Vinay,
Can you explain your questions more clearly? Do you mean convert a column table to a row table?

Support for triggers for tables with clustered column-store indexes

Hello,
We are very excited about the new clustered column-store indexes in SQL 2014 and our performance tests shows significant performance gains. However, our existing functionality relies on triggers and they are not allowed on tables with column-store
indexes. Does anybody have information as to whether allowing triggers on tables with column-store indexes is anywhere on the radar?
Thank you!
P.S. We spent a lot of time considering various work-around to avoid triggers, but the amount of work we would have to do is simply overwhelming, so we are considering delaying our upgrade until such functionality hopefully becomes available.

My gut reaction is that this restriction is likely to remain for the forseeable future. Columnstore indexes are intended for data warehouses, and while I don't do data warehouses myself, I cannot say that a fact table is where I expect to find a trigger.
But if you think that there is a good business case for permitting triggers on columnstore tables, submit a suggestion on
https://connect.microsoft.com/sqlserver/feedback
Note that if you give some business-oriented explantion why this is a great benefit, it is more likely that Microsoft is likely to listen.

Usage of sequence for uploading data into tables(column store) using CSV

How to make use of sequence when data is uploaded into table(column store) with the CSV file ?

Hi Sharada,
You may have to follow the below steps:
1) To load the data from flat file to a Staging table using IMPORT command
2) You have to call the procedure to load the data further into final Table.
a) Have a look on this procedure to load data :
SAP HANA: Generic Procedure using Arrays to Load delta data into Tables
b) See my reply on the syntax on how to use "Sequence"
Auto-Incrementor in stored procedure!
You will have to ensure that you frame your insert query in such a way to have the sequence number in the target table.

Disadvantages of Oracle RDF Store

Hello all,
what are in your opinion the main disadvantages of the Oracle RDF Store? What are the disadvantages compared to other repository systems (e.g. Fedora Commons)?
It would be great to get some feedback from anyone who has experienc in daily work and development with Oracle RDF Store?
Thanks in advance and
best wishes,
Oliver

I do a comparison and have enough positive facts (but
if there are any others I would take them, too). I
compare .NET, Forms, OAF and APEX with Pros and Cons,
so I need the Cons of Forms ;-)Your comparison logic is incorrect. (sorry to say it, but I couldn't help my self).
you are trying to compare a peanut with an apple and a cucumber and a water melon, they cannot be compared.
so are these products, each of them is under seperate category, and if you want to choose one, you need to think what your business needs are.
Is it for a small business, what are the transaction types? do you need OLAP? how many users? integration? platform? interface...... (you want me to continue :-) ???? )
.NET, try to deploy an application written in .NET against a database other than ACCESS or SQL server.....
APEX it's complete different technology than forms, the requirement needs can't be applied on both.

SQL syntax error different between enviroments after converting to column store indexes

We have two 'identical' SQL boxes with SQL 2012 enterprise edition installed. In our Developer enviroment only, we just converted to Column Store indexes. Now when we run this SQL, we get the following error message, ONLY in the Dev enviroment
SELECT DISTINCT RatingDescription
FROM Rating
where RatingDescription > 1
Msg 245, Level 16, State 1, Line 2
Conversion failed when converting the varchar value 'No Rating Needed' to data type int.
However, this SQL works in our production enviroment and the prod enviroment has the same data and schema as DEV. As soon as we disable the column store index on the dev box, the SQL works without any problems. Is this a known feature or bug
that anyone knows about?
Additional info:
The RatingDescription field is a varchar(100) and contains numbers and text.
Current SQL server editions on both servers:
Microsoft SQL Server 2012 (SP1) - 11.0.3000.0 (X64)
Enterprise Edition (64-bit) on Windows NT 6.2 <X64> (Build 9200: )

So I need to amend my statement.
This statement does fail as everyone is saying:
SELECT DISTINCT RatingDescription
FROM Rating
where RatingDescription > 1However, this statement does not failSELECT DISTINCT RatingDescription
FROM Rating
where RatingDescription > 1
AND analystName = 'Bob'I left out the analystName critiera because I didnt think it mattered but clearly it allows the SQL to run because Bob has no text for ratings. However my finding are still true, that this exact SQL runs successfullywhen I disable the CS index, and as soon as I enable/rebuild it it fails with the message Conversion failed when converting the varchar value.

How to trigger alert Column store unload for reason :unused resource

Good day,
I have an issue with the column store unload.
As for this alert in hana studio, there are 3 reasons for the alert. Reason: Low memory, Explicit, Unused resource.
First one is lack of memory, so the column table is unloaded. Second is because someone unloads a column table by SQL. These two reason we can see easily and they are usually main reasons for this alert. However, i can't trigger the last one.
Is there any good method to trigger it?
I attached some screens files of the workaround.
Any help will be appreciated.
Thank you!
Best regards
Geoffrey Zhang

Hi Geo
not too sure if the idea for KBAs has changed but in my understanding they were never meant to replace documentation or to provide complete topic overviews.
Given the nature of this alert, it would be weird to
a) get an alert at all for this
b) have someone reacting to it.
The function to unload containers after they haven't been used in a long time is part of the garbage collection in SAP HANA. Why would it be necessary to have an alert for that?
And then what should anyone do about it? What do DBAs usually do, when long unused data gets displaced to disk?
Exactly: nothing
Concerning my remark about SCN usage of SAP employees: I meant that there are plenty of SAP internal forums and communities available where you can probably get less exposure to the rest of the world and might get answers that provide you with more detailed information than what is possible in SCN.
As English is the corporate language and used in SCN as in the internal forums I don't see how that is an obstacle for using the internal forums.
About your unanswered questions: just like any other forum, SCN is based on voluntary contributions. There should be no expectation about how long it takes to get answers.
Nobody is paid to answer the questions here, so it's all on a community basis.

[Oracle 11g] Store filename as VARCHAR2 and its content as XMLType

Hi all,
The version of Oracle used is 11.2.0.3.0.
I would like to load a XML file into a table from AIX with a Shell script.
Here is the test case table:
ALTER TABLE mytable DROP PRIMARY KEY CASCADE;
DROP   TABLE mytable CASCADE CONSTRAINTS;
CREATE TABLE mytable (
   filename VARCHAR2 (50 BYTE),
   created DATE,
   content SYS.XMLTYPE,
   CONSTRAINT pk_mytable PRIMARY KEY (filename) USING INDEX

So I add a step to create the control file from a generic one like this:
#!/bin/ksh

    cat $CTL | sed -e "s/:FILE/$f/g" > $f.ctl

Now I want to store the basename of the file : ${FILENAME}.
How can I do that ?
The problem is that I can no more write "LOBFILE (filename)" because it does not point to the correct path of the file !!!
Someone can help me please ?
Thanks.
