Persist XML Data to Database Table - Generic XML Schema
Hi,
I would like to represent data in XML format and persist to any database tables.
The ideal xml is like:
<TABLE NAME="TABLE1">
<TABLEDEF><COLUMN NAME="COLUMN1"/><COLUMN NAME="COLUMN2"/></TABLEDEF>
<ROW><COLUMN VALUE="value1"/><COLUMN VALUE="value2"/></ROW>
<ROW><COLUMN VALUE="value11"/><COLUMN VALUE="value22"/></ROW>
</TABLE>
<TABLE NAME="TABLE2">
</TABLE>
The XML could then be parsed, and saved to database with JDBC by manually composing the statement strings.
To reduce the coding effort (xml parsing, JDBC connection, etc), are there any open source projects available to achieve the above purpose? The popular O/R mapping tools like Hibernate, Castor, etc, can't handle this scanario because they require the knowledge of the tables on the server side in order to create the mapping files in advance.
Thanks for the help!

Efficient way of updating data to database table
what is the efficient way of updating data to database table .
i have huge amount of data in my internal table , how to use update statement in this case .
1. database table having 20 fields ,
2. one is key field and suppose 20 th field i want to change .
3. I have data for only 2 fields , i.e for ( 1 st and last 20 th field ) .
i can't use update statement in loop , as it is not good practice(hits database several times ) .
do it effects all the 20 fields for particular record .Hi,
Use UPDATE statement , check below description from SAP help.
UPDATE dbtab FROM TABLE itab. or UPDATE (dbtabname) FROM TABLE itab.
Effect
Mass update of several lines in a database table.Here, the primary key for identifying the lines tobe updated and the values to be changed are taken from the lines of theinternal table itab.
The system field SY-DBCNT contains the number of updated lines,i.e. the number of lines in the internal table itab which havekey values corresponding to lines in the database table.

its very urgent.
thanks in advance

Edited by: its urgent on Dec 25, 2011 9:31 PMHi ,
1.)You must have to create a EO based on custom table and then VO based on this EO eventually to save the values in DB
2.) the row.setNewRowState(Row.STATUS_INITIALIZED); is used to set the the status of row as inialized ,this is must required.
3.) When u will create the VO based on EO the viewattributes will be created in VO which will be assigned to the fields to take care the db handling .
You must go thtough the lab excercise shipped with you Jdeveloper ,there is a example of Create Employee page ,that will solve your number of doubts.
Thanks

How to insert data in database table
Hi experts,
How to insert data into database table using internal table from function module.Hi,
As per my understanding are you looking for the complete API feature of data insertion into the database using the Locking Mechanism? If yes, then you need to create a Lock Object using the Primary keys of the Primary Table and Secondary Tables. You need to call the lock object first and then you need to make the entry into the table. This principle is based on 'All or None Concept'.
For the insert Statement Key word you can have a look at the following link:
http://help.sap.com/abapdocu/en/ABAPINSERT_SOURCE.htm
Hope this helps.
Thanks,
Samantak. -

How to insert large xml data into database tables.
Hi all,
iam new to xml. i want to insert data in xml file to my database tables.but the xml file size is very large. performance is also one of the issue. can anybody please tell me the procedure to take xml file from the server and insert into my database tables.
Thanks in advanceUnfortunately posting very generic questions like this in the forum tends not to be very productive for you, me or the other people who read the forum. It really helps everyone if you take a little time to review existing posts and their answers before starting new threads which replicate subjects that have already been discussed extensively in previous threads. This allows you to ask more sensible questions (eg, I'm using this approach and encountering this problem) rather than extremely generic questions that you can answer yourself by spending a little time reviewing existings posts or using the forum's search feature.
Also in future your might want to try being a little more specific before posting questions
Eg Define "very large". I know of customers who thing very large is 100K, and customers who think 4G is medium. I cannot tell from your post what size your files are.
What is the content of the file. Is it going to be loaded into a single record, or a a single table, or will it need to be loaded into multiple records in a single table or multiple records in multiple tables ?
Do you really need to load the data into exsiting relational tables or could your application work with relational views of the XML Content.
Finally which release of the database are you working with.
Define performance. Is it reasonable to expect to process this kind of document on this machine (Make, memory, #number of CPUs, CPU Speed, number of discs) in this period of time.
WRT to your original question. If you take a few minutes to search this forum you will find a very large number of threads with very similar titles to yours. These theads document a number of different approaches that can be used to solve this problem.
I suggest you start by looking for threads that cover topics like DBMS_XMLSTORE, XMLTable(), Relational Views of XML content, loading XML content in relational tables. -

Exporting data from database tables to a XML file
Hi,
We want to export data from Oracle database tables to an XML

about it ?
Can we extract data only from an Oracle8 database, or can we
extract data from Oracle7.3 databases too ?
Any help in this regard would be appreciated.

Start by downloading the XML SQL Utility and make sure you have
the approriate JDBC 1.1 drivers installed for your database.
There are samples which will get you going included in the

Can not find product , sku attributes data in database table
Hi there,
I find it really strange to find data in database related to product and sku. I set up the commerce reference store and store is up and running fine. Catalog is fine too. I am not able to find data related to sku attributes in database.
I have a product_id xprod2511 which has 11 child skus such as xsku2511_1, xsku2511_2 and so on. sku xsku2511_1 is blue color and size 4. When I search for this two sku attributes (color and size) information in dcs_sku_attr table with sku_id as xsku2511_1, no rows returned. In fact, I looked into few other sku tables but I am not able to find the information about color and size of a sku in any database table.
this is the query I am running:
select * from dcs_sku_attr where sku_id = 'xsku2511_1'
Can someone please let me know the table name where this information regarding color and size resides in?
Thanks a lot.In dyn/admin If you try and view the definition file of ProductCatalog repository, then under sku item descriptor you would see the color and size property which would be under some table tag, that table tag table name should be the table holding these values.
the other question(may be silly) is that I hope that you are executing sql in correct schema, that is cata or catb schema (select * from catA.dcs_sku_attr) where the actual product catalog data resides. -
Uploading excel data to database table
Dear Experts,
I have an Excel file which was downloaded from SQL database, now I need to export this data into my 'ztable', for this first I created an internal table of ztable structure and tried to upload into this table through ''TEXT_CONVERT_XLS_TO_SAP".
But I was unable to get data into the internal table(incompatible type), so now I created an internal table of character type fileds now I able to get data to this internal table, but to put this internal table data to actual database table it gives error, here the actual problem is the fields of internal table are getting concated with blank spaces(observed through debug), I unable to condense these blanks also, (I have created an Excel of my own and put data into it and uploaded that data there is no problem working fine but this problem occurs only for the excel downloaded from SQL db)
The problem occurs for quantity and currency fields(I tried through standard FMs also to convert data types ), Could plz suggest something..........
Thank you
Regards
SrinivasHi,
To upload excel sheet into database table, define a types which is of same as table fields.
and try it with the function module TEXT_CONVERT_XLS_TO_SAP
Here is a sample code:
CALL FUNCTION 'TEXT_CONVERT_XLS_TO_SAP'
EXPORTING
I_FIELD_SEPERATOR ='X'
i_tab_raw_data = fs_truxs( TYPE of truxs_t_text_data.)
i_filename = '<FILE-PATH>'
tables
i_tab_converted_data = <Internal Table>
EXCEPTIONS
CONVERSION_FAILED = 1
OTHERS = 2
IF sy-subrc <> 0.
MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.
LOOP AT <internal-table> INTO field string.
INSERT <DATABASE- TABLE> FROM <field string>.
ENDLOOP.
Hope this solves the issue.

Select data from database tables with high performance
hi all,
how to select data from different database tables with high performance.
im using for all entries instead of inner joins, even though burden on data base tables is going very high ( 90 % in se30)
hw to increase the performance.
kindly, reply.
thnksAlso Check you are not using open sql much like distict order by group by , use abap techniques on internal table to acive the same.
also Dont use select endselect.
if possible use up to n rows claus....
taht will limit the data base hits.
also dont run select in siode any loops.
i guess these are some of the trics oyu can use to avoid frequent DATA BASE HITS AND ABVOID THE DATA BASE LAOD. -

How to maintain the data into database table
Hi,
experts,
how to maintain the data into database tableThere are several ways to maintain data in the database
1. Use table maintanance generator . You can create this using SE11 and data can be edited through SM30.
2. Loginto SE11 with the specified table and check the ATTRIBUTES tab. There you can set some parameters for maintaining the database. When you set Maintain database, you edit the data thorugh SE11 it self
3. Through Se16 as well.
4. A small abap program can do the above task as well.
Thanks,
Raj
