Dear All,
I got a doubt b/n select and cursor.
I read in one oracle book that select into clause will actually tries to get the data twice, Whereas the cursor will query only ones.
Is this the case in Oracle 10g or both the select and cursor will fetch the data only ones.
Ex
select sal into v_sal from emp where empno = 7788 --> Ones it hit the data, oracle will again scan the entire set of records in the emp table for another match.
Whereas
Cursor c_sal is select sal from emp where empno = 7788; --> This will do the fetch operation only ones.
Is this the case still True in Oracle 10g or 11i.
Appreciate your help.
Thankyou very much
Madhu Kthe query is processed as follows (this is from ora doc)
Parse:
– Search for identical statement
– Check syntax, object names, and privileges
– Lock objects used during parse
– Create and store execution plan
Execute: Identify rows selected
Fetch: Return rows to user process
for cursor also same things are performed, but cursor is private sql area in which you can processes one row at a time, you can use cursor in your pl/sql program and access one row a time,
so if you say,
cursor c1 is select * from emp;
c1 is private sql area where you can processes single row of emp , make comparisons, calculations etc,
once you close the cursor this area is released and can be used by another cursor,
the basic query processing rules remains the same, -
Can I use a select and update statement in a single jsp file?
I want to update the BUY table everytime I would add a SELL transaction.....I want to minus the stocks that I sold to those that Ive bought before.....
note: I used a seperate table in BUY and SELL transaction
After I Have added a transaction, I want to update the buy table. This is my problem, can I used both SELECT and UPDATE statement at the same time in a single jsp file for example like this:
select * from test, test1;
update test
set total_shares=total_shares-Stotal;
where stock_code=Scode AND name_broker=Sbroker;
Can i have both of these statements in the same jsp file in oder to update the buy table?
Or can anyone suggest how can process that update?THANKS!
--------------------Can i have both of these statements in the same jsp file in oder to update the buy table?Yes. But wouldn't it have been easier just to try it?

Correct usage of select and option statements
Is it ok if I say this in my option statement?
<select name="XYZ" onchange="return valChange(this)">
<option <%=Selected%> value="100"><%=100%%></option>Or should the option tag just contani the variable names instead of values directly?
like this
<option <%=aTmpSelected%> value="<%=abc%>"><%=fslr%></option>where atmpselected contains selected,
abc contains 100,
and
fslr contains 100%,
as values?
Please specify using an example.
Thanks for your time.Tutorial on how to use select elements:

The value attribute is the string that gets passed to the form when it's submitted. The text between the <option></option> tags is what gets displayed for that choice. You can use a conditional to decide if "selected" gets added to the html. -
JDBC Sender - Different number of records selected and updated.
Hi people,
We have a JDBC -> Abap proxy scenario. The JDBC sender is pooling an Oracle database to retrieve data from a table X, each 30 minutes. The select and update statements in jdbc sender are below
SELECT FIELD1, FIELD2, FIELD3 FROM MY_TABLE WHERE STATUS = 1
UPDATE MY_TABLE SET STATUS = 2 WHERE STATUS = 1
Sometimes the message sent to Abap proxy has, for example, 400 records. Looking at runtime workbench, message monitoring, for the same message there is a log like this
Channel SENDER_JDBC_CHANNEL: Query executed successfully. Start update
Channel SENDER_JDBC_CHANNEL: 510 row(s) updated successfully
Someone has already experienced something like this? How can I handle this to guarantee to update only those read records?
regards.
robertiHi All,
Even we are facing the same problem.
In our scenario, receiver is SAPR3. (IDOC)
Will this parameter serialization work in our case?
1. SELECT XBLNR, WERKS, MATNR, MDV01, BACKFLQUANT, STATUS, SAPTIMESTAMP, PITSTIMESTAMP, PMTIMESTAMP, BATCH FROM PMBPITS.PITS_UNITY WHERE STATUS = '01' and rownum<200 .
2. UPDATE PMBPITS.PITS_UNITY SET STATUS = '02' , SAPTIMESTAMP = sysdate WHERE STATUS = '01' and rownum<200 ( currently the value is rownum < 5 )
Thanks!!

Combine select and update into single statement,without bind-variable
I have a problem, that I think is not possible to solve the way I want to, but I just wanted to check before leaving the idea...
I am looking for a way to combine the select and the update statement into one single statement. This is what I wan't to achive: select some data, and update the data selected before returning them.
On this site http://www.psoug.org/reference/update.html I see that the following are possible:
var bnd1 NUMBER
var bnd2 VARCHAR2(30)
var bnd3 NUMBER
UPDATE employees
SET job_id ='SA_MAN', salary = salary + 1000,
department_id = 140
WHERE last_name = 'Jones'
RETURNING salary*0.25, last_name, department_id
INTO :bnd1, :bnd2, :bnd3;
I need to have this as a single statement, and cannot use bind-variables. So I was hoping that something like this could be possible:
UPDATE customer c
SET c.HAS_CREDIT ='1'
WHERE c.HAS_CREDIT = '0'
RETURNING c.CUSTOMER_NO, c.FIRSTNAME, c.LASTNAME
where c.HAS_CREDIT = '1'
But this doesn't compile, complaining of missing into (ORA-00925: missing INTO keyword). And even though I would like this to be possible because this would solve my current problem, I think it would be very confusing. For instance; would the where clause of the returning part be operating after the update or before?
Any comments or suggestions on how to get it work in a single statement, or should I just leave this path straight away?Hi,
RETURNING only works with bind variables, see
http://download-uk.oracle.com/docs/cd/B19306_01/appdev.102/b14261/returninginto_clause.htm#sthref3006
The real problem is that the form of RETURNING clause with bind variables is only valid for single row update or insert statements.
To update (or insert) multiple rows and return the data, you will need to use
RETURNING BULK COLLECT INTO clause. See
http://download-uk.oracle.com/docs/cd/B19306_01/appdev.102/b14261/tuning.htm#sthref2236

Mixed Signal Graph, Selected Cursors, and Cursor Position Problems
I'm trying to work around an issue with a single multiplot cursor on a mixed-signal graph (doesn't work right, R&D bug report #100830) by grabbing the selected cursor x-position and updating that position across all four cursors, as seen below:
However, I'm having two problems.
One, the selected cursor is not always the actual selected cursor. Quite often, especially when selecting and dragging cursors 3 & 4 (indexed 2 & 3), the selected cursor shows up as 0 or 1.
Two, and the one I'm more concerned about, is the fact that the four cursors X-positions never completely line up. In every case, whichever cursor is deemed to be "selected", the other three will align to some point (the same for all three) that is offset from the actual value. Please note that the X-values in my demonstration are identical (1000 points from 0.001 to 1) so I don't see this as being some snap issue where the value is offsetting to the closest available on the other arrays.
I've attached my scratchpad demo.vi as an illustration.
Any help or insight is appreciated.
Thanks,
Mike Webster
Attachments:
demo.vi 47 KBI believe I found where the issue resides at least and a workaround. This is a problem with XY graphs in general when trying to programmatically control the cursor position. Somehow, the software goes looking for the nearest point instead of the identical point and has some sort of issue with its search algorithm. Switching from attempting to match position to copying the cursor 'index' completely cleared up the problem I was having. In the particular application I'm working on, the four graphs have identically spaced data on the X-axis, so this solution should work fine for me.

Auditing DDL and DML statements of selective IP addresses....
Hi all,
DB : 11.2.0.2 64 bit
OS : RHEL 5.7 64bit
Hi all,
I want to audit all DDL and DML statements for some selective IP Addresses or hostnames.
I read about Fine Grained Audit. I got the following code to enable auditing of nondatabase user's actions(Application users).
created policy for client identifier.......
BEGIN
DBMS_FGA.ADD_POLICY(OBJECT_SCHEMA => 'OE',
OBJECT_NAME => 'ORDERS',
POLICY_NAME => 'ORDERS_FGA_POL',
AUDIT_CONDITION => 'SYS_CONTEXT(''USERENV'', ''CLIENT_IDENTIFIER'') = ''Robert''',
HANDLER_SCHEMA => NULL,
HANDLER_MODULE => NULL,
ENABLE => True,
STATEMENT_TYPES => 'INSERT,UPDATE,DELETE,SELECT',
AUDIT_TRAIL => DBMS_FGA.DB + DBMS_FGA.EXTENDED,
AUDIT_COLUMN_OPTS => DBMS_FGA.ANY_COLUMNS);
END;
But I want to audit all DDL and DML statements for a particular schema say ABC from selective IP addresses or hostnames so how can I do this?
Pl suggest.....
Regards,
Andy.Hi,
You could :
1. create a function, say myfunction, returning 1 if you want to audit, 0 otherwise
This function would test sys_context('userenv','ip_address') within the desired IP address to be audited
2. create your fga on the objects you want to audit adding the clause audit_condition=>'myfunction=1'

Palette highlight and Cursor do not align, making palette select difficult
Folks,
Don't expect I'm the first to report this but I didn't find anything about it from a forum search so better to report it then ignore it.
Under the Eclipse IDE when trying to select one of the actions listed lower on the palette the cursor does not match the highlight. The lower you go in the list the farther off the alignment gets until, in order to select Sequence, the last item in the list, you have to have the cursor very far down past the sequence icon in order for it to be actually highlighted and selectable. Only then can it be selected and dragged to the designer view. The topmost icons align the cursor to the highlight well but the further you go down the list the farther off the alignment gets.
Designer is 0.9.13, Eclipse is at Version: 3.1.0 Build id: I20050627-1435
Thought you might want to know.Apparently the distribute spacing command only uses the top object as a reference. I would say that's a bug.

Performance Measure - Select SUM and Collect Statement.
Dear All,
I am using YNME_PROCESS_PO_CUST Badi in this i writing some validation Delivery Completion.
For that i need to calculate GR qty and Delivery quantity based on this i need some validation. But here i confussed which statement i need to use for bast performance.
Note: In Badi Item Level Data will be process one by one..like item level 10 then 20 then 30......Like that
Code will like that---
SELECT SUM( menge ) FROM ekes
INTO l_delqty
WHERE ebeln = ls_mepoitem-ebeln
AND ebelp = ls_mepoitem-ebelp.
SELECT SUM( dabmg ) FROM ekes
INTO l_grqty
WHERE ebeln = ls_mepoitem-ebeln
AND ebelp = ls_mepoitem-ebelp.
l_delqty1 = l_grqty - l_delqty.
IF l_delqty1 NE 0.
ls_mepoitem-elikz = ''.
CALL METHOD im_item->set_data( ls_mepoitem ).
ENDIF.
I check in SE38 response is better in this code.
Other code may be like that .. same data will be like upper/
SELECT * FROM ekes
INTO CORRESPONDING FIELDS OF TABLE it_ekes
WHERE ebeln = ls_mepoitem-ebeln
AND ebelp = ls_mepoitem-ebelp.
LOOP AT it_ekes.
MOVE-CORRESPONDING it_ekes TO it_ekes1.
COLLECT it_ekes1.
CLEAR it_ekes.
ENDLOOP.
READ TABLE it_ekes1 INDEX 1.
IF sy-subrc EQ 0.
l_delqty1 = it_ekes1-menge - it_ekes1-dabmg.
ENDIF.
IF l_delqty1 NE 0.
ls_mepoitem-elikz = ''.
CALL METHOD im_item->set_data( ls_mepoitem ).
ENDIF.
Can any send me document--
Regard
DKHi,
Single Select statement is certainly better.
But no need to do select * and using into corresponding fields. These will reduce the performance. Also the loop statment is not absolutely correct. Following could be a sample code.
TYPES: BEGIN OF gx_ekes, (maintaining same sequence of fields as in select statement, this way no need of into corresponding fields)
ebeln type ebeln,
ebelp type ebelp,
menge type bbmng,
dabmg type dabmg,
END OF gx_ekes.
DATA : lit_ekes TYPE TABLE OF gx_ekes,
git_ekes TYPE TABLE OF gx_ekes,
wa_ekes TYPE gx_ekes.
SELECT ebeln
ebelp
menge
dabmg
FROM ekes
INTO TABLE it_ekes
WHERE ebeln = ls_mepoitem-ebeln
AND ebelp = ls_mepoitem-ebelp.
LOOP AT lit_ekes INTO wa_ekes.
COLECT wa_ekes INTO git_ekes.
CLEAR: wa_ekes.
ENDLOOP.
CLEAR: lit_ekes.
Now the first record in git_ekes will have the sum as only one line item is being passed in the user exit.

Insert and select in one statement
using MS Sql server and VB i can execute two queries Insert and select in one statement e.g. (insert into (....) values (...) Select @@Identity).
how can i do the same thing using Oracle and VB. ???
It gives error. here's what i want to do.
(insert into table1 (...) values (...) Select table1_sequence.currval from dual )
KhurramHere's how you can achieve the same Oracle :-
Test Db>desc tmp1;
Name Null? Type
EMP_NO VARCHAR2(10)
EID NUMBER
Test Db>insert into tmp1 (emp_no, eid)
2 select '123', 1
3 from dual;
1 row created.

It goes nuts for hours and the next day it acts completely fine. My macbook is impossible to work with when the problem is active; it randomly clicks, drags, selects and even selects words (in a yellow colour) to come up with latin(?!) translations.
Ive tried the reset (option+cmd+r+p) and it seemed to work at first but now it doesnt seem to have any effect whatsoever.
Also tried to apply pressure to the entire surface of the trackpad or just the top corners; no effect whatsoever.
It's been quite an expensive purchase for a young student like me and i've really enioyed it until last week.
I'd be relieved if someone came up with a solution; especially since its warranty has expired for half a year now.Hi there Bram3,

Invalid Cursor state Exception - Help required
Hi,
I'm having a web page(JSP), which is making use of 3 ResultSet objects. Using the first two, i'll populate two different Drop down list, with values from database(Access) while loading the page for first time.
Now if the user select any value from any (or both) of drop down list and clicks submit, i need to display all values in database, meeting the criteria from first & second drop down list. For this selection, i'm using the third ResultSet variable. While executing the query, i'm sure that 3rd ResultSet is returning some value. But when i try to retrieve the value to a string variable, i'm getting the Invalid cursor state exception.
Throughout the page, i haven't closed any of the ResultSet. When i closed the first and second ResultSets in the third function(where 3rd ResultSet is used), i'm not getting any value. Its returning like ResultSet closed.
Please help me to get this solved. It's very urgent because without this, i cannot proceed further. Please share your ideas.
Thanks in advace for your valuable helpIf you open a new resultset within the same statement, all previously opened will be closed.

Invalid cursor state when trying to insert record
Hi everyone!
I'm using JDBC-ODBC bridge to connect to a mySql database, which works fine. Then I try to insert new records, but this only works for the first record in the table.
When there is already a record in the table, I always get "[Microsoft][ODBC Driver Manager] Invalid cursor state" when calling the updateRow()-method of the result set.
Here is my code: // open db connection
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection conn = DriverManager.getConnection("jdbc:odbc:TTManager", "xxxx", "xxxx");
// Prepare SQL statement
java.sql.Statement stmt = conn.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_UPDATABLE);
ResultSet result = stmt.executeQuery("SELECT * FROM Player");
result.moveToInsertRow();Then all fields are filled in this manner: result.updateString("Name", name);And finally the insertRow should be written to the db: result.insertRow();But at this point it gives the mentioned error, including these messages: at sun.jdbc.odbc.JdbcOdbcResultSet.setPos(JdbcOdbcResultSet.java:5272)
at sun.jdbc.odbc.JdbcOdbcResultSet.insertRow(JdbcOdbcResultSet.java:4132)Since I'm very unexperienced with Java, I guess (or hope^^) it's just some stupid beginner's mistake.
Oh, almost forgot to mention: The new record's data doesn't violate any unique-constraints on the table, all fields are explicitely filled and all variable's data types are matching their according field types!
Any help would be appreciated!
reinskiOk, I needed to help myself and this is what I found out:
If the table already contains records, it is not enough to doresult.moveToInsertRow();but I must beresult.last();
result.moveToInsertRow();I didn't find any explanation and even the code examples from the Sun tutorial don't mention this, so I guess it's a bug occurring in my poor IT environment: DB server running mySQL 5.0.0-alpha on a P1-233-MMX w/ 64MB under WinNT4 (hey don't laugh!!^^).
Maybe this information is of use to someone having similar problems...
