Retrieving multiple column names from a Primary/Export key ResultSet

ALTER TABLE "APP"."FLIGHTAVAILABILITY" ADD CONSTRAINT "FLIGHTAVAIL_PK" PRIMARY KEY ("FLIGHT_ID", "SEGMENT_NUMBER", "FLIGHT_DATE");
I am looking at the above statement and from the DDL statements of the database i am working with and the most information I can get out of the meta data is this
APP FLIGHTAVAILABILITY FLIGHT_DATE 3 FLIGHTAVAIL_PK
How important are the other two columns to this primary key
same for the export key meta data
FLIGHTAVAILABILITY FLIGHT_ID 1 3 3 FLIGHTS_FK2 FLIGHTS_PK 7
yet
ALTER TABLE "APP"."FLIGHTAVAILABILITY" ADD CONSTRAINT "FLIGHTS_FK2" FOREIGN KEY ("FLIGHT_ID", "SEGMENT_NUMBER") REFERENCES "APP"."FLIGHTS" ("FLIGHT_ID", "SEGMENT_NUMBER") ON DELETE NO ACTION ON UPDATE NO ACTION;
there are 2 columns referenced for the Foreign key to be generated and I can only retrieve info for the one foreign key.

Apologize above is duplicate post ignore this post

How to get only column names from different tables as single table columns

Hi All,
I have one requirement in which we want only column names from different tables.
for example :
I have three tables T1 ,T2, T3 having
col1 clo2 clo3 --> T1 ,
col3 col5 ,clo6 --> T2 ,
Clo6 col8 col9 --> T3
columns i want to get only all Column names from all table as single Resultset not any data from that how can i get that empty resultset
because this empty result i want to bind in datagridview(front end) as Empty resultset
Please tell me anyways to do this
Niraj Sevalkar

If I understand you want an empty result set, just with metadata. SET FMTONLY do the trick:
SET FMTONLY ON
SELECT Col1, Col2, Col3, ....., Coln
FROM
T1 CROSS JOIN T2 CROSS JOIN T3
SET FMTONLY OFF
Another alternative is to include an imposible contition
SELECT Col1, Col2, Col3, ....., Coln
FROM
T1 CROSS JOIN T2 CROSS JOIN T3
WHERE 1 = 0
If you are using a SqlDataAdapter in your client application. You can use the FillSchema method. the select command may be any select statement that returns the columns you want. Under the covers FillSchema will call SET FMTONLY ON.
If you are using SqlCommand.ExecuteReader you can pass SchemaOnly to CommandBehavior argument. SET FMTONLY ON is called under the covers. Again the select command may be any select statement that returns the columns you want.

Retrieving old column values from a after delete trigger dynamically

I have a single audit table for deletions
and the table structure has the following columns
1: table_name
2: column_name
3: column_value
I am writing a trigger on tables for which i want to have delete audits and i am dynamicaly
retrieving the column names but i am unable to retrieve the column value dynamically;
I tried to use the following statement but doesn't return the column value
sql_stmt:= 'select :1 from dual';
execute immediate sql_stmt into col_value using
':old.'| |v_col_name;
where v_col_name is the name of the column which i retrieve dynamically using the
dbms_sql.describe_columns procedure.
Is their any way if i can retrieve the old column values in the trigger dynamically if i already
have the column names in variables..
Thanks in advance.

I don't know if Kevin's tip Help Mr. Sameer, but it did help me gain access to pre-deleted row column values.
I did discover, however, that if the columns from the about-to-be-deleted row are used as inserts into another table, Oracle serves up a nasty-gram informing the user that values from the about-to-be-deleted table are unreliable.
I was able to circumvent this constraint by assigning the about-to-be-deleted column values to local PL/SQL varables, then perform the insert using the variable values.

How to retrieve the parameter names from a JSP page ? Urgent Please

Hello,
Can anybody tell me how to retrieve the parameter names from the JSP
page. (without using getParameterNames() method.)
The problem with the getParameterNames() method is I get the Jumbled output.
I need it very badly
With regards
Ananth R
email:[email protected]
[email protected]

Dear duffymo,
My primary intention is to convert the JSP form information into a XML file.
If I do not get the Parameter names in the correct order how can I maintain
tag order in XML file.
For ex: (JSP PAGE VIEW)
Name--
FirstName
MiddleName
LastName
Address--
Street1
Street2
City
Country
&so on
(XML File to be generated)
<Name>
<FirstName>Value</FirstName>
</Name>
<Address>
<street1>value</street1>
</Address>
& so on
If I use getParameterNames() to get all the parameter names(Which form the tag names in the XML file ) the Enumeration object it returns will not be in the same order as the text fields in JSP.From this I can not construct a meaningful XML file.
order means: Order of entry on the page, from top to bottom
That's it
Waiting for your responses

How to retrieve multiple columns using "returning" in the Insert query.

hi,
wanted to know how to retrieve multiple columns using "returning" in the Insert Query.
For retrieving one column we write the query as follows:
Insert into TABLE values(1,2,3,4) returning COLUMN1 into PARAMETER
But can we retrive multiple columns in the same query?
am using oracle 10g and coding in .NET

Hi,
You can definetely get multiple values from a single query using the 'returning' clause.
Eg : insert into emp (empno, ename, job, deptno) values (7324,'ADAM','MARKETING',30) returning ename, deptno into var1, var2; PN : var1 & var2 to be declared as varchar2 & number respectively.
More insight into the 'RETURNING' clause in this link.

Query the column names from Public database links

Greetings,
I would like to retrieve the list of all the column names from a public database link. A regular ALL_TAB_COLUMNS doesn't seem to be working.
Thanks
John9569

Hi,
I think your DBA needed to create a synonym for you to have access of that remote database view.
CREATE SYNONYM synonym_name
FOR view_name@db_link;Then you can find the column names by
DESC synonym_nameGuru's , please correct me If I am wrong.
Thanks

How to pull only column names from a SELECT query without running it

How to pull only column names from a SELECT statement without executing it? It seems there is getMetaData() in Java to pull the column names while sql is being prepared and before it gets executed. I need to get the columns whether we run the sql or not.

Maybe something like this is what you are looking for or at least will give you some ideas.

"Automatically retrieve CD track names from internet" not working

I'm about to begin re-ripping all my CDs (400+) which I haven't done since at least 14yrs ago in order to take advantage on newer/better formats. I was excited to see that iTunes can automate a lot of this process with the following two options:
- When you insert a CD: (Import CD and Eject)
- [ ] Automatically retrieve CD track names from internet
Found in the "Playback" settings of iTunes 10.1.1
However after inserting my first CD, I noticed it started to import without downloading the track names first. Obtaining track names manually is working for me because if I choose "Advanced -> Get track names" it accesses Gracenote DB and works fine.
It's just the automatic operation after inserting a CD that is not working. This causes me to have to:
1) Insert CD
2) Choose "Advanced -> Get track names"
3) Click "Import CD"
4) Eject
as opposed to the one supposedly promised step of "Insert CD" and have the other 3 things happen automatically.
I've tried deleting my iTunes plists in my ~/Library/Preferences/ folder but it still works the same.
Any suggestions?

You can seach the Gracenote site directly. I don't know if that would help you decide which option you needed to use.

How to Select data using same column name from 3 remote database

Hi,
Can anyone help me on how to get data with same column names from 3 remote database and a single alias.
Ex.
SELECT *
a.name, b.status, SUM(b.qty) qantity, MAX(b.date) date_as_of
FROM
*((table1@remotedatabase1, table1@remotedatabase2, table1@remotedatabase3)a,*
*(table1@remotedatabase1, table1@remotedatabase2, table1@remotedatabase3)b)*
WHERE b.dept = 'finance'
AND a.position = 'admin'
AND a.latest = 'Y' AND (b.status <> 'TRM') AND b.qty > 0;
GROUP BY a.name, b.status ;
NOTE: the bold statements is just an example of what I want to do but I always gets an error beacause of ambiguous columns.
Thanks in advnce. :)

Each object must be uniquely identified. So you cannot do this:
select * from (table1@remotedatabase1, table1@remotedatabase2, table1@remotedatabase3) a3 objects cannot share the same alias. Example:
SQL> select * from (dual, dual) d;
select * from (dual, dual) d
ERROR at line 1:
ORA-00907: missing right parenthesisYou need to combine the objects - using a join or union or similar. So it will need to be done as follows:
SQL> select * from (select * from dual d1, dual d2) d;
select * from (select * from dual d1, dual d2) d
ERROR at line 1:
ORA-00918: column ambiguously definedHowever, we need to have unique column names in a SQL projection - so the join of the tables need to project a unique set of columns. Thus:
SQL> select * from (select d1.dummy as dummy1, d2.dummy as dummy2 from dual d1, dual d2) d;
DUM DUM
X X
SQL> I suggest that you look closely at what scope is and how it applies in the SQL language - and ignore whether the objects referenced are local or remote as it has no impact to fundamentals of scope resolution.

How to Retrieving Mandatory Filed name from Tcode.

Hi,
I need to retrieve mandatory field names from tcode like (mm01) using abap programming..
How to find that field name is mandatory?
Thanks and Regards,
Meena

Hi Meena,
I guess you need to manually find it out and make z-table which can be used for further logic.
Once you have table for required fields, you can even add/remove any field depending on your requirement.
I also faced the same issue and we maintained it in ztable as follows.
MANDT
FIELDNAME
STATUS
For STATUS , create fixed domain values as "REQUIRED", "HIDDEN", "GRAYED OUT".
I hope this will help you.

Getting column names from SYS_REFCURSOR

Hi everybody, i have a SYS_REFCURSOR in a procedure. And i open it and fetch cursor to a record as follows:
OPEN curgroup FOR vexpr2;
LOOP
FETCH curgroup INTO recType;
END LOOP;
recType is a Record, has two variables. Anyway, the question is can i get the column names from refcursor?
like recType.COLUMN1 (Column1 is not a record variable ) ????
or is there anything else to perform this operation?

Hi,
Despite what Billy states it is very possible to get the column names from a weak ref cursor, or describe a ref cursor with PL/SQL. It has been possible since 8i, it just relies on the little known fact that a ref cursor in PL/SQL translates directly to a ResultSet in Java so we can use a tiny JSP in the DB.
Here is the link to the completely free, Open Source code which allows you to do this: [XUTL_REFCURSOR|http://www.chrispoole.co.uk/apps/xutlrefcursor.htm]
And a little example:
SQL> variable scott_cursor refcursor
SYS@ORA10GR2
SQL> begin
2 open :scott_cursor for select * from scott.emp;
3 end;
4 /
PL/SQL procedure successfully completed.
SYS@ORA10GR2
SQL> begin
2 xutl_refcursor.describe_columns(:scott_cursor);
3 end;
4 /
PL/SQL procedure successfully completed.
SYS@ORA10GR2
SQL> select col_name from xutl_described_columns;
COL_NAME
EMPNO
ENAME

MGR
HIREDATE

SQL>As the demo shows describing the ref cursor does not affect the cursor in any way, it is not selected from. It is not converted into a DBMS_SQL cursor and can be passed to a front end.
[XUTL_REFCURSOR|http://www.chrispoole.co.uk/apps/xutlrefcursor.htm] is designed to have exactly the same output and uses the same return type as DBMS_SQL DESCRIBE COLUMNS, to enable pre-existing code that uses that API to be quickly re-used.

How to retrieve column name from Excel using POI HSSF eventusermodel?

Hi ,
I am simply reading the excel sheet and writing in a txt file. I have done the following in the switch construct. It works fine but I want to retrieve only the column header. But this code gives me all available strings in the excel sheet. Any pointer would be greatly appreciated.
case SSTRecord sid :
         SSTRecord sstrecord = (SSTRecord) record;
         for (int i=0; i<sstrecord.getNumUniqueStrings(); i++){
              System.out.println(" Column name" + sstrecord.getString(i));
break;bye for now
Sat

try labels:
        case LabelSSTRecord.sid:
            LabelSSTRecord lrec = (LabelSSTRecord) record;
            if (lrec.getRow() == 0) {
                System.out.println(" Column name "
                        + sstrec.getString(lrec.getSSTIndex()));
            break;
