Generate database tables from Business Components

Is it possible to generate the database tables from a set of existing business components?
This would be a handy feature to have, similar with JPA tables generation based on Entity Beans.
Thanks

Generating database tables from Java classes

Hi,
I've encountered a number of tools which will create Java classes from database tables (e.g. JDeveloper has this functionality, Abator provides this for iBATIS, etc...).
However, I've not been able to locate any tools that perform the opposite job - i.e. given a Java class, it generates a database table (or, presumably, some SQL).
It's been suggested to me that Hibernate might provide this sort of capability, but if anybody has any experience of doing this, in any tool, I'd be interested to hear about it.
Thanks,
Alistair.

Many thanks for the pointers.
duffymo: I've taken a look at Middlegen (http://boss.bekk.no/boss/middlegen/index.html) but it seems that the first step is to specify the database schema, whereas I'm looking to generate the schema from existing code. Or have I missed something?

Create database tables from an xsd

Is it possible to generate database table from a given xsd using toplink ?
I want to use these tables to persist java objects obtained by unmarshalling the xml (corresponding to this xsd).
Thanks in advance,
Mahima

Hello Mahima,
Although you could use TopLink to generate a database schema from an XSD using a combination of wizards available in the TopLink Workbench, the resulting database schema would probably not be an optimal design. If you're interested we can talk about how to use this approach as a guide.
Is your main use case the generation of a database schema or the actual movement of database data to/from XML?
Using a combination of TopLink's object-relational and object-XML support to move data between XML and a relational database is a valid pattern. Refer to the discussion thread below for some approaches at setting up the metadata.

Modify database table from internal table

Hi All,
I need to update database table from internal table which is having around 30000 records.
I am using MODIFY tabname FROM TABLE int_tabname...
Using this statement, I can modify the databse records very well. But user has some additional requirement.
He wants that the table should be modified from the internal table and after modification we should have the erroneous records to be displayed if any.
e.g. if 1500 records out of 30000 are erroneous then only 28500 records should be updated and 1500 records should be displayed as erroneous records so that the user can correct them and use them again for executing the program.
Is there any FM which imports the database table name and internal table, modifies the database and exports an internal tanle with erroneous records?
Any help will be appriciated,
Regards,
Neha

Hi

advises before updating this datbase table plz lock that table to avoid incosistency
write the logic for modifying
Modify the database table as per new dunning procedure

How to Import/Export database tables from one server to other in oracle8i

Hello friend,
Please can any one tell me how to import/export groups of database tables from one server with oracle to another using VB.net. It would be nice if some one can provide some code of it.
I am a software developer and I am in middle of a large project development, in which I need to export a large oracle database from one server to another efficiently.
Its very urgent so please someone help me.

At command prompt (source db)
set ORACLE_SID=db_name
exp system/password@db_name full=y buffer=104857600 file=(c:\file1.dmp, c:\file2.dmp....) log=c:\exp.log filesize=2000M
Then ftp the export dump files (in binary) to the other server or copy to target server over the network.
At command prompt (target db)
set ORACLE_SID=db_name
imp system/password@db_name full=y ignore=y buffer=104857600 file=(c:\file1.dmp, c:\file2.dmp....) log=c:\imp.log filesize=2000M
If the path names of the datafiles are going to be different in the target server (as compared to the source), then precreate the tablespaces before import. Set buffer value accordingly.

How to update database table from Internal Table

hi experts,
Can anyone please assist me in inserting records to a database table from an Internal Table
whose structures are identical.
Thanks in Advance,
Sudhaa............

Hi Sudha,
Here are some example of update and insert:
UPDATE SFLIGHT SET PLANETYPE = 'A310'
PRICE = PRICE - '100.00'
WHERE CARRID = 'LH' AND CONNID = '0402'.
This example overwrites the contents of the PLANETYPE column with A310 and decreases the value of the PRICE column by 100 for each entry in SFLIGHT where CARRID contains u2018LHu2019 and CONNID contains u2018402u2019.
TABLES SPFLI.
DATA WA TYPE SPFLI.
MOVE 'AA' TO WA-CARRID.
MOVE '0064' TO WA-CONNID.
MOVE 'WASHINGTON' TO WA-CITYFROM.
UPDATE SPFLI FROM WA.
MOVE 'LH' TO SPFLI-CARRID.
MOVE '0017' TO SPFLI-CONNID.
MOVE 'BERLIN' TO SPFLI-CITYFROM.
UPDATE SPFLI.
CARRID and CONNID are the primary key fields of table SPFLI. All fields of those lines where the primary key fields are "AA" and "0064", or "LH" and "0017", are replaced by the values in the corresponding fields of the work area WA or the table work area SPFLI.
DATA: ITAB TYPE HASHED TABLE OF SPFLI
WITH UNIQUE KEY CARRID CONNID,
WA LIKE LINE OF ITAB.
WA-CARRID = 'UA'. WA-CONNID = '0011'. WA-CITYFROM = ...
INSERT WA INTO TABLE ITAB.
WA-CARRID = 'LH'. WA-CONNID = '1245'. WA-CITYFROM = ...
INSERT WA INTO TABLE ITAB.
WA-CARRID = 'AA'. WA-CONNID = '4574'. WA-CITYFROM = ...
INSERT WA INTO TABLE ITAB.
UPDATE SPFLI FROM TABLE ITAB.
This example fills a hashed table ITAB and then overwrites the lines in SPFLI that have the same primary key (CARRID and CONNID) as a line in the internal table.
Insert statement :
TABLES SPFLI.
DATA WA TYPE SPFLI.
WA-CARRID = 'LH'.
WA-CITYFROM = 'WASHINGTON'.
INSERT INTO SPFLI VALUES WA.
WA-CARRID = 'UA'.
WA-CITYFROM = 'LONDON'.
INSERT SPFLI FROM WA.
SPFLI-CARRID = 'LH'.
SPFLI-CITYFROM = 'BERLIN'.
INSERT SPFLI.
If the database table does not already contain a line with the same primary key as specified in the work area, the operation is completed successfully and SY-SUBRC is set to 0. Otherwise, the line is not inserted, and SY-SUBRC is set to 4.

HI,Can anybody pls explain me, while extracting database table from sap-r/3

HI,Can anybody pls explain me, while extracting database table from sap-r/3 to sap-bw using GENERIC DATA SOURCE it will ask us Name of the APPLICATION COMPONENT what does it means?

Application Component is a collcetion of tightly coupled S/W component. You can think of it is like folder, where all the related S/W will be put in. Like MM will have all the DS related to MM.

Updating database table from an internal table

Hi All,
I am updating a database table from an internal table.
I am changing the non-key fields in that table.
when I check sy-subrc = 4.
Record already exists, because I am changing non-key fields of the
database table.
Is there any addition like to accept the duplicate keys with update.
Alternatively, I have used Modify, It is adding new record,
Again, I have search the old record and use Delete on the database table.
Thanks & Regards,
Kalyan Chandramouli
SAP ABAP Consultant

Hi,
You are right, the field which I am trying to change is a part of primary key.
Because, sy-subrc = 4. says,
No line with specified primary key exits in the database table.
I have a Z-tabel, with Kunnr Vkorg Matnr Bzirk Bztxt Split_percentage
In this table primary key consists of KunnrVkorgMatnr+Bzirk.
I am able to change the Split_percentage using UPDATE.
Now, my client want to change Bzirk, Bztxt also in the table.
How can I Go.
Thanks & Regards,

Access SAP database table from different SAP server

Hi,
May i know is that possible to access the SAP database table from server A to server B without write a program on server A? Is it possible for direct access the SAP database table.
Best regards,
Gan

Hello,
you could use the RFC-Modules RFC_READ_TABLE or RFC_GET_TABLE_ENTRIES on server A.
Precondition: you need a RFC-Destination from B to A.
And a little drawback: you get only the first 512 byte of each table entry.

z_mver-perkz, z_mver-mgv01,
z_mver-mgv02, z_mver-mgv03.
insert z_mver client specified.
*if the data already had been in table z_mver then sy-subrc will not be
*equal with zero. (this can be *interesting for you - (this list is
*not necessary but it maybe useful for you)
if sy-subrc ne 0.
write:/ z_mver-matnr, z_mver-werks.

endloop.
1. This solution is recommended only if the database table is NOT a standard SAP database table .

How to load data from XML DOM into tables using Business Components


Hi,


I need to upload XML file (it's not a problem) an load data (DOM tree) from this file into relationan tables. This filelooks like this:

Is there any Business Components support to obtain this ? What about primary and foreign keys values (there is no in XML file). How to place this XML data in appropriate tables ?

Pl post details of exact OS and database versions, along with a sample of the XML file and description of the tables. What have you tried so far ?

JDev 10g: Problem when generating database objects from UML diagram

Hi,
I have noticed following problem.
I made some business components through UML diagrammer in 9.0.3. From the diagram I generated database objects. It worked fine.
When I doing the same thing in 10g, the generation fails on several tables with the message that the "identifier is too long".
Looking at the SQL produced in one of the failing tables. In 9.0.3 following is produced:
create table sfs_document_def (
id number constraint document_definition_id_check not null,
caption varchar2(100) constraint document_definition_caption_ch not null,
index1 number,
owner_type number constraint document_definition_owner_type not null
alter table sfs_document_def add (constraint documentdefinition_primary_key primary key (id));
And in 10g following is produced:
create table sfs_document_def (
id number,
caption varchar2(100) constraint sfs_document_def_caption_check not null,
index1 number,
owner_type number constraint sfs_document_def_owner_type_ch not null
alter table sfs_document_def add ( constraint documentdefinition_primary_key primary key (id));
alter table sfs_document_def add ( constraint document_definition_id_check check ("id" is not null));
alter table sfs_document_def add ( constraint sfs_document_def_caption_check_10 check ("caption" is not null));
alter table sfs_document_def add ( constraint sfs_document_def_owner_type_ch_10 check ("owner_type" is not null));
It seems that column that are set not to be null in 10 g first get a constraint creating the table and then when altering the table. Furthermore, notice that the name of the second constraint is longer than 30 chars, which is reason to the error when creating the tables.

Thanks for reporting the issue. I have managed to reproduce your problem and logged a bug to get the problem fixed.
Thanks,
