How to get the table name of a field in a result set

hi!
i have a simple sql query as
select tbl_customerRegistration.*, tbl_customerAddress.address from tbl_customerRegistration, tbl_customerAddress where tbl_customerAddress.customer_id = tbl_customerRegistration.customer_ID
this query executes well and gets data from the database when i get ResultsetMetaData from my result set (having result of above query) i am able to get the field name as
ResultSetMetaData rsmd = rs.getMetaData();//rs is result set
String columnName = rsmd.getColumnName(1);
here i get columnName = "Customer_id"
but when i try to get the tabel name from meta data as
String tableName = rsmd.getTableName(1); i get empty string in table name....
i want to get the table name of the respective field here as it is very important to my logic.....
how can i do that.....
please help me in that regard as it is very urgent
thanks in advance

So far as I'm aware, you can't get metadata information about the underlying tables in a query from Oracle and/or the Oracle drivers. I suspect, in fact, that the driver would have to have its own SQL parser to get this sort of information.
I'm curious though-- how do you have application logic that depends on the name of the source table but not know in the application what table is involved? Could you do something "cheesy" like
SELECT 'tbl_customerRegistration' AS tbl1_name,
tbl_customerRegistration.*

I really liked your audit table concept. You inspired me to modify it so that, the entire recordset gets captured and added a couple of other fields. Wanted to share my end result.

How to get the table name and bind columns names in an INSERT statement ?

I have an INSERT statement with input parameters (for example
INSERT INTO my_table VALUES (:a, :a, :a)) and I want to know
without parsing the statement which is the name of table to
insert to and the corresponding columns.
This is needed to generate the SELECT FOR UPDATE statement to
refetch a BLOB before actually writing to it. The code does not
know in advance the schema (generic code).
Thanks in advance,
Joseph Canedo

Once you have prepared your statement, you can execute the
statement with the OCI_DESCRIBE_ONLY mode before binding any
columns. Then you can use OCIParamGet to find out about each
column (column index is 1-based). You should get OCI_NO_DATA or
ORA-24334 if there are no more columns in the statement. Note
that the parameter descriptor from OCIParamGet is
allocated/freed internally by OCI; you do not need to manage it
explicitly. The parameter descriptor is passed to OCIAttrGet in
order to obtain for instance the maximum size of data in the
column OCI_ATTR_DATA_SIZE. You can also get the column name in
this way, although I do not remember the #define off the top of
my head. Getting the table name appears to be much more
difficult; I have never had to do that yet. Good luck. -Ralph

How can I get the table name of a field..

How can I get the table name of my column?

I'm using the JDK 1.3 trying to get a table name of a column from a result set. Regardless of what driver I'm using (ODBC Bridge/Oracle) I always get a null returned. Does this method work?
If not, if I'm doing an SQL query that uses more than 1 table and each table has a return of the same column name, how do I distinguish which table the column is from. Thanks

You can use ResultSetMetaData interface and method
String getTableName(int column)
This should return you the table name.
To get ResultSetMetaData object, you can use
ResultSetMetaData getMetaData()
method of ResultSet interface.

How to get the table of value field? and can we expand the technical limits

Dear
I have created value field in COPA with KEA6. And now, I need the table which the value fields are saved. Yet, I have tried a lot to find it and get failure? Can any guy help me? Please tell me how to get the table of a value field.
And another question is that, can we extend the technical limits for the number of value field for ECC6.0?
We have a note for R.4.x Please see below:
OSS note 160892
You can display the length of a data record using Transaction KEA0 ('Maintain Operating Concern'). After you have navigated to the 'Characteristics Screen' or to the 'Value field Screen' choose menu path 'Extras -> Technical Limits'.
The maximum displayed here under 'Length in bytes on the DB' is the maximum length permitted by the Dictionary. The reserve required for the release upgrade must be subtracted from this value.
To increase the allowed number of the value fields, increase the value that is assigned to field ikcge-bas_max_cnt (FORM init_ikcge_ke USING fm_subrc, approx. line 165) in Include FKCGNF20. It specifies the number of the possible value fields. The corresponding part of the source code is attached to the note as a correction.

Hey john,
My requirement is as follows
I have created a Rank for Total sales by Region wise i.e RANK(SUM(Dollars By Region)) in a pivot table.
My pivot table looks like this
COLUMN SELECTOR: TOTAL US , REGION , DISTRICT , MARKET
---------------------------------------------------- JAN 2009          FEB 2009        MAR 2009
RANK              REGION                  DOLLARS           DOLLARS        DOLLARS DOLLARS
1 CENTRAL 10 20 30 40
2 SOUTHERN 10 30 30 70
3 EASTERN 20 20 20 60
4 WESTERN 10 20 30 40
When i select the District in column selector
Report has to display rank based on Total Sales by District. i.e
------------------------------------------------- JAN 2009         FEB 2009       MAR 2009
RANK             DISTRICT              DOLLARS           DOLLARS        DOLLARS DOLLARS
for this i need to change the fx of rank i.e RANK(SUM(Dollars By Region)) to RANK(SUM(Dollars By District)) and fx of Region i.e Markets.Region to Markets.District dynamically.
so , i need to capture column name of the value selected from the column selector and dynamically i need to update the fx 0f RANK & fx of region.
do you have any solution for this?

How to get the table with no. of records after filter in webdynpro

Dear Gurus,
How to get the table with no. of records after filter in webdynpro?
Thanks in advance.
Sankar

Hello Sankar,
Please explain your requirement clearly so that we can help you easily.
To get the table records from your context node use method get_static_attributes_table()
data lo_nd_mynode type ref to if_wd_context_node.
data lt_atrributes_table type wd_this->elements_mynode.
lo_nd_mynode = wd_context->get_child_node( name = wd_this->wdctx_mynode ).
lo_nd_mynode->get_static_attributes_table( importing table = lt_atrributes_table ).
Note: You should have already defined your context node as a Dictionary Structure.

Hi Expert,
I found that we can use Interface INavigationHelperService to read Portal Role selected by user at runtime from http://scn.sap.com/thread/52194
But this class is available in SAP NetWeaver 7.30 Enterprise Portal .
But in SAP NetWeaver 7.0 Enterprise Portal that interface is not available.
INavigationService is available there.
But didn't get any proper discussion on this interface for the same requirement.
Can you please help me.

How to get the function name/ID of the current page

HI,
I searched the forum and google, but it is not clear on how to get the function name of the current page.
I have 4 functions in my self service A ,B,C,D (seeded page links ) they all have to go to a page called hhhPG. Based on which function user is clicks I have to show the data in hhhPG.
so my question is how to get the function name ? I mean I need to know if user click on link A , B, C or D link and came to this page.
I found below in one forum and also there is getfunctionID in pageContext , but I do not know what to pass to getfunctionid("???") to get value.
FunctionSecurity funcSecurity = pageContext.getFunctionSecurity();
Or is there a better way of know where user is coming from ? like geturl....
Please help, I need this ASAP.
Thank you.

Use below to find out how the user came into the page
FunctionSecurity funcSecurity = pageContext.getFunctionSecurity();
boolean isFunc1 = funcSecurity.testFunction(funcSecurity.getFunction("YOUR_FUNCTION_SHORT_NAME1"));
boolean isFunc2 = funcSecurity.testFunction(funcSecurity.getFunction("YOUR_FUNCTION_SHORT_NAME2"));
boolean isFunc3 = funcSecurity.testFunction(funcSecurity.getFunction("YOUR_FUNCTION_SHORT_NAME3"));
boolean isFunc4 = funcSecurity.testFunction(funcSecurity.getFunction("YOUR_FUNCTION_SHORT_NAME4"));
So one of them will be true based on the function the user came in.
Write your logic based on these flags.
Regards,
Peddi.
