How to use a bind variable in XE for accessing data from different sources

Hi,
I am new to XE and trying to create an application like this:
(region source)
Select * from v$session@:P1_DATABASE ;
My intention is to give the name of the database at runtime to fetch the relevant data.
But I am getting error like this
1 error has occurred
Query cannot be parsed within the Builder. If you believe your query is syntactically correct, check the ''generic columns'' checkbox below the region source to proceed without parsing. ORA-01729: database link name expected
Doesn't work even when I check the "Generic Columns" and run the query at the run time (same error).
Can some one please help!
Regards,
Santosh Loke

Hi,
There are rules using names in SQL. I think you could use dynamic SQL to achieve the goal in your case. It is not clear for me what are you going to do. Moreover bind variable are difficult to use some times.
You could start with something simple as a report and a form.

How to use a bind variable in an IN clause

I am trying to use a bind variable in an IN clause where the column is a varchar2 type. Something like:
select *
from test
where test_column in (:bindVariable)I have tried assigning the bind variable comma separated strings (eg. test,test,test) and comma separated strings with quotes (eg. 'test','test','test'). Neither of these work. Does anyone know the correct way to do this?
Thanks in advance.

How to use a bind variable in a table-validated flexfield

Hi,
I want to prepare a table-validated descriptive flexfield, which uses as source a select statement.
So, in the form "Validation table information" I use as table name the statement:
(SELECT my_procedure('test_value') FROM DUAL)
Up to here it works fine.
But instead of 'test_value' I want to use the value of a field in the form or a value of another flex (using $FLEX$ bind variables).
Please advice if it is possible to perform this in "table name" statement. I use it in "where/order by" clauses and it works fine.
Thank you.

How can I use notifications to send data from different sources to thesame chart?

Hi,
I am using the "Continuous Measurement and Logging" template project that ships with LV 2013.
It is extremenly helpful for figuring out messaging between the acquire, graph, and log loops. (Thanks NI!)
I've run into a snag however.
I would like to modify it so that my graphing loop receives data notifications from two acquisition sources via notifiers.
I'm having trouble getting data from both sources to display on the same chart.
I've isolated the issue in the attached vi.
Here's what happens:
1. I create data from 2 parallel loops and send the data to a third parallel loop with notifiers.
2. The third loop receives data from only one of the loops because one of the receiving notifiers just times out instead of receiving data.
Can someone suggest how I can fix this?
Thanks.

test notification loop.vi ‏42 KB

Here is my modification of your VI. I put notes on the block diagram to explain the changes. It uses a queue for the data transfer to avoid loss of data. It uses a notifier to stop the loops. All local variables and Value property nodes have been eliminated.
The way the loops are stopped will likely leave some data in the queue. No more than one or two iterations of each of the data acquisition loops. If you need to guarantee that all data has been displayed (or saved in a real application), then you need to stop the acquisition loops first and read the queue until you know it is empty and both of the other loops have stopped. Then stop the display loop and release the queue and notifier.

How to use the direct bytebuffer in JNI? Accessing JDBC from C application.

I am working on a project to access JDBC Driver within C application. The invocation JNI is used.
To get better performance, I use the preparedStatement for dynamic sql. This need to transfer much parameter data from C to JDBC for PreparedStatement object in JVM. I think this maybe get improvements by using the new direct bytebuffer function from JDK1.4. However I cannot find an example code to get start. Could someone provide some ideas for this?
Currently, I directly call JDBC API in C application through JNI, so there is no java codes. Only c file using JNI call.
My understanding is to use the direct bytebuffer feature, I also need to have java codes to process the JDBC API call and then can share the same memory between Java and C. Please correct me if wrong.
Any input is appreciated.

I am trying to get the best performance for the solution, using JDBC libs in a C application. So I am considering to use the direct bytebuffer in the solution to pass parameters to JDBC and get result sets from JDBC side.
For your questions,
1. Why don't you just write the database access in C?
You mean to directly call JDBC API in C through JNI, right? My plan is to wrap the JDBC API by java and expose seldom interface to C native code, so reduce the JNI call between C and JAVA. If directly call the JDBC API call from C, the number of JNI call maybe more.
No I mean what I said. In C, no java at all, why don't you write code to access the database?
2. The database access itself is going to be slower than anything that you do in C or java.
Exactly. I just want to find each potential points to get performance improvements for the whole solution. I also did some optimization work for the database call. The goal is to get the best performance from C application to database through JDBC libs.
Then I suggest you profile it.
3. Why don't you use import/export files and the database tools? This is often significantly faster with volume processing.
Sorry, I am not very familar with some functions of JNI. Could you explain, " +Why don't you use import/export files and the database tools+"?
Nothing to do with java, jni nor C.
Major (or perhaps everything that is a real 'database') comes with additional tools. Amounst those tools will be command line tools capable of importing and exporting data from the database. In processing bulk data they will always be faster than anything you can do in JDBC.

How to fetch data from different sources into one source (like into Ztable)

hi friends,
As per our client requirements they want to develope an Inventory and an Ontime delivery report in BO on top of Oracle database.
Situation is some thing like they have ECC 6.0.and they want to collect all inventory and ontime delivery data at one place.According to me that could be one Ztable in which we can gather all data.Apart from that they are going to use Data Integrator in which they can directly fetch the data from R/3 system(They dont want to have BI system) and put all data in Oracle DB.On top of ORacle BO person can develop BO reports.
My question is how to fetch all data at one place and what are the tables going to be use.
kindly help me out as its very important project.
Thanks
Abhishek

The following is my standard reply to those who need to get old data from a backup in one account and add it to another account. The method described here may be applied to your case. It would be a bit of a long process, though.
When connected to the account you want to GET data from, Go to Settings>iCloud and turn all data that is syncing with iCloud (contacts, calendars, etc.) to Off.
When prompted choose to keep the data on the iPhone.
After everything is turned off, scroll to the bottom and tap Delete Account. Next, set up a new iCloud account using a different Apple ID and turn iCloud data syncing for contacts, etc. back to On. When prompted, choose Merge. This will upload the data to this new account.
Note that this only affects the "Apple data" like contacts, calendars, reminders, etc. Many third party apps also use iCloud to store data files there. These files may be lost in the process, unless the apps also keep the data locally on the device.
NOTE: Photos in the photo stream (if you use it) will not transfer to the new account. It is advised that you save the photos to a computer before performing the account switch.

How to make this function module as RFC to get data from different system?

Hi
I am trying to use following function module . This function module is used to copy data from one cube to another cube within same system however I need a this should happen across two different system. How can I use this function module to make it remote call to different system and do the same function what it is doing ?
Name of function module -
RSDRT_INFOCUBE_DATA_COPY
Any help would be really helpful
AG

HI,
let us say you want to copy the data of a cube in system A to a cube in system B .
1) create a RFC function module in system B (in this function module call the function module RSDRI_CUBE_WRITE_PACKAGE to update the data), this RFC function module should have same parametersa as RSDRI_CUBE_WRITE_PACKAGE .
2) write a program in system A .. read the data from the infocube using the function module RSDRI_INFOPROV_READ and call the RFC function module in system B that you have created..
for the details of the parameters to pass to these two function modules use the RSDRT_INFOCUBE_DATA_COPY and get the required code
Thanks

How to use a bookmarklet to rewrite URL for access to scientific journals

The majority of educational institutions in the US and UK use a system called ezproxy to allow unfettered access to scientific journals. To access a journal, users simply need to add something like this "ezlibproxy1.ntu.edu.sg" to the URL. There are lots of automatic ways to do this, including zotero, but probably the simplest is to use a bookmarklet, eg:
http://www3.ntu.edu.sg/lib/ezproxy/proxy_bookmarklet.htm
If there was a "bookmarks toolbar" on fennec, then I think I'd be able to click on the bookmarklet to modify any URL. Sorry if this already exists and I have missed it. Is there an alternative way to achieve this? It would save me a lot of time!

How to properly set bind variables

Dear All,
I am currently confused about how to properly set my Bind Variables
I have this view using HR standard schema
Select *
from Employees
where EMPLOYEE_ID = :EMP_IDI somehow see three options on how to use this bind variable in an application module.
Option 1:
ViewObjectImpl view = this.getEmployeesView();
VariableValueManager vm = view.ensureVariableManager();
vm.setVariableValue("EMP_ID", value);
view.executeQuery();Option 2:
ViewObjectImpl view = this.getEmployeesView();
view.setNamedWhereClauseParam("EMP_ID", value);
view.executeQuery();Option 3:
EmployeeViewImpl empView =this.getEmployeesView();
RowSetIterator it = empView.createRowSetIterator(null);
empView.setEmployeeId(value);
empView.executeQuery();Question is which is which and what should I use?
JDEV 11G PS3

I use is this
DCIteratorBinding iteratorStatus = Util.getIterator("NameIterator");
operationBinding.execute();
Util is reserved in a class.
public static DCIteratorBinding getIterator(String iteratorName){
return getDCBindings().findIteratorBinding(iteratorName);

Method :Want to Use Z-Table for Accessing Data

that table . Not able define the table in method.
Kindly tell me how to do it .
Thanking you in Advance
Siladitya

Hello Siladitya
I assume your problem is the definition of an itab for selecting data from your Z-table. In case of classes you have to use table types and workareas, e.g.:
METHOD name_of_interface_method.
DATA:
lt_itab TYPE TABLE OF <name of z-table>,
ls_record TYPE <name of z-table>.
SELECT * FROM <name of z-table> INTO TABLE lt_itab.
LOOP AT lt_itab INTO ls_record.
ENDLOOP.
ENDMETHOD.

How to find out if a SQL is using a bind variable or not?

In order to make a SQL use consistent execution plan, I want to create a profile for a SQL. But I need to know if a SQL is using bind variable or not to create a profile for all the same SQLs except the literal value. How can I do that?
Thanks in advance

You can tell if an SQL statement uses a bind variable by looking at the SQL statement.
If you look in the program that submits the SQL statement you can see how it constructs, prepares, and executes the statement.
If you are just looking at the SQL in the shared pool then depending on how the statement is written and the setting of database parameters like cursor sharing then it can be more difficult but if you see a constant (actual value) that is a constant. A bind variable would appear as a name in the where clause where that name does not exist any of the tables referenced in the query. Note it is technically possible to create pl/sql variables with the same name as columns in the query but that is poor coding and leads to issues.
Note - To Oracle two versions of the otherwise same query where one has a constant and the other has a bind variable are not the same query and often produce different plans. This is a common error made by developers new to Oracle when using explain plan. To explain a query that uses bind variables place a ":" in front of the variable name in the SQL submitted to explain plan.

How to have the BIND variables value using the TKPROF utility.

WE have a JAVA application and Oracle 9i database.We need to figure out what all select/update/insert sql staements are firing if i am doing one complete processing in my JAVA front application.
Initally I have planned for using TKPROF utility after makeing AUTO_TRCE=TRUE in the database.But the problem is that all select/insert/update sql statements are using the BIND variables in the JAVA code and same is coming/printing on the trace file also.
can we print out the BIND variables values also,while making the TRACE ON?
eg: trace is generaitng the all insert statements like below.
insert into TEST(Column1,Column2) values(:1,:2);
I want to know the value of :1 and :2 bind variables.
If you have any cluse about it please let me know.
Mitesh Shah

Thanks Guys,
I got the BIND variable values in the TRACE file.Previously i was searching on the OUtputfile.
I am pasting the same trce file format.Can you please verify it.Is i am looking the correct file and corect location.

How to declare a bind variable with 'date' data type in command prompt?

how to declare a bind variable with 'date' data type in command prompt?
sql>variable q date;
when i execute it show list of datatypes

Hi,
As Lokanath said, there are no DATE bind variables.
You can use a VARCHAR2 bind variable, and convert it to a DATE in your SQL statment.
If you're using SQL*Plus, consider a substitution variable. It won't be as efficient as a bind variable, but it will be as convenient.
For example:
DEFINE first_entrry_date = "DATE '2010-06-20''
SELECT   ...
WHERE   entry_date >= &first_entry_date
{code}

How to share a bind variable across multiple view objects?

Hi, Can someone tell me if it's possible to share a bind variable among multiple view objects within an application module? My web page displays data from different VOs on different regions. But all data should be controlled by the same bind variable, which appears in all queries. How can I achieve this?
Please help.

Best to state your JDev version, and technology stack (eg. ADF BC) when posting.
I can think of 2 approaches.
1) Create a parent VO based on SELECT :bindVar FROM dual, then create links between your other VOs and the parent
2) Create a AM client interface method that programatically sets the bind variable in each VO.
Can you specify your use case? This one tends to come up when discussing effective from/to dated queries.
