How to retrive data from SAP Archive (from Cluster or Content Table)

Hi,
I am working on HR -ABAP where i have a scenario to retive employee photo and disaplay as output in smartforms.And these employee photo are stored in Cluster table SDOKCONT1 in SAP Archive Link (storage type - SAP System Database).
Anybody can tell me the way how to retrive data ( employee Photo ) from this cluster and display its output in smartform dynamically.
Regards,
Sourabh Shrivastava

Hello Sourabh,
If I am not wrong, there are two parts two your query...
a) Data or Content Retrieval
b) Displaying Retrieved content
Here is my feedback
a) The Content can be Retrieved using the FM ARCHIV_GET_TABLE.
Pass the Archive Object, SAP Object and the SAP Object ID and based on the Connection table entries (TOA*), the underlying Content Repository (T-code OAC0) is determined and a request for synchronous retrieval is made to the Content Server.
b) Display of Retrieved content is normally done through dedicated viewers (Ex: Livelink Viewer) or front-end applications (Excel, Word) based on the Protocol (OAA3/OAA4) specified in the Content Reository Configuration. Hence, to my knowledge, you cannot display the content directly in the Smartform.

How to retrive data from the database by using resultset metadata

Hi
I am very new to java programing.please help me anyone...
In my table 20 fields are there.I want to retrive those fields and put it into arraylist.and return the arraylist.
regards
guru

First get Column count by using getColumnCount() method
Then Get The Column name by using getColumnName(int column)
By using column name You can retrieve values
eg:
String columeName=null;
int count = mymetadata.getColumnCount();
for(int i=1;i<=count;i++) {
columeName = getColumnName(i);
//Retrive values from resultset buy using columeName
}

How to retrive data from corrupted ipod

i was using my Apple Ipod as a storage device to keep data back up of my personal file. Unfortunately data in this device is corrupted and i dont know how to retrive it now.
Can somebody help me to retrive these data files.

If you previously synced to the computer then you may be able to recover use of the iPod without erasing the iPod by following the instructions here:
Disabled Recovery-must use syncing computer.
If you do not have a backup to restore from then yo may be able to get some info from the restored iPod by:

How to retrive data from MDM Tuple?

Hi,
How to retrive MDM Tuple data into a java Application? Here I have to fetch the data from MDM Tuple and populate it in a list. can anybody please help me in doing this.
Thanks.

Hi Sree,
Any one of the below mentioned APIs can perform the record retrival from a Tuple.
- Record.getFieldValue(tupleFieldId)
If the tuple record is part of the original table record that can be obtained using one of the Retrieve commands responsible for retrieving records.
- TupleValue.getFieldValue(tupleFieldId)
If the tuple record is part of another tuple record (nested tuple structure)
Hope this helps.

How to get data from Oracle using Native SQL in SAP.. Problem with date

Hi Masters.
I'm trying to get data from an Oracle DB. I was able to connect to Oracle using tcode DBCO. The connetion works fine
I wrote this code and it works fine without the statement of where date > '01-09-2010'
But i need that statement on the select. I read a lot about this issue, but no answer.
My code is (this code is in SAP ECC 6.0)
DATA: BEGIN OF datos OCCURS 0,
      id_numeric(10),
      component_name(40),
      comuna(10),
      record_id(10),
      status,
      sampled_date(10),
      END OF datos.
DATA: c TYPE cursor.
EXEC SQL.
connect to 'LIM' as 'MYDB'
ENDEXEC.
EXEC SQL.
SET CONNECTION 'MYDB'
ENDEXEC.
EXEC SQL PERFORMING loop_output.
SELECT ID_NUMERIC, COMPONENT_NAME, COMUNA, RECORD_ID, STATUS, SAMPLED_DATE
into :datos from lims.SAMP_TEST_RESULT
where     date > '01-09-2010'
ENDEXEC.
EXEC SQL.
disconnect 'MYDB'
ENDEXEC.
How can i get the data from that date?? If i delete the where statemet, the program works well, it takes 30 mins and show all the data, I just need the data from that date.
Any help
Regards

Please refer the example in this link which deals with Oracle date format.
You can finnd a command DECODE which is used for date formats. If you have a look at whole theory then you will get an idea.
