No Return Data Buffer

I have two threads in my programm that use FlexMotion API. One thread is responsible for monitoring the digital ports and current axes position. In this thread I call flex_read_limit_status_rtn, flex_read_home_input_status_rtn, flex_read_vs_pos_rtn and flex_read_port_rtn. The second thread do motion control (blend, wait for blend complete ...). After a random period of time and, in many cases, after a succefull motion control, I get NIMC_noReturnDataBufferError (-70003) error from my first thread without the other thread doing any kind of motion control. I got an answer that FlexMotion API is thread-safe in MFC, so I'm not using any kind of locking mechanism before calling FlexMotion functions in the threads. Reading the error description
didn't help me to pinpoint the cause. Why I'm getting this error ?

Tulio,
There are several reasons that you may be encountering this error. First of all, you want to make sure that you are using FlexMotion 5.2. There are several issues with previous versions and V 5.2 has fixed many of them.
About your error. What is happenning is that the driver is making a request to the board. And the onboard operating system and supposed to respond by putting an answer in the return data buffer on the board.
When the operating system for the board was originally designed, it was tested on much slower computers. If you are overwhelming the onboard OS with queries through the driver, you may put it in a unstable state.
So try the following:
1) try upgrading the driver (if you havn't already)
2) make sure that you don't overwhelm th
e driver.
Let me know if this helps at all. Post your code if you don't figure out what is going on.

Can not find Flush Return Data Buffer.vi

When I try to start my Labview program I get a "Error -70025 occurred at Read Home Input Status.vi" because the Return Data Buffer is not empty.
I searched for the Flush Return Data Buffer.vi in the Labview library but it is not there.
Where can I find it?

Hello Mishka,
The Flush Return Data Buffer.vi should be located in your functions palette at Vision and Motion>>73xx>>Advanced>>Flush RDB.vi. Alternatively, you can press ctrl+space on your keyboard to open the quick drop menu and then search for Flush RDB.vi.

GPShell: 0x80100008 (The data buffer to receive returned data... )

Hi all,
My test applet generate response of zero bytes of length based in Le field in APDU command. When I require up to 256 bytes, responses are OK.
Problem occurs when I expect e.g. 257B (Le = 0x000101), in this case I've got following error:
send_APDU() returns 0x80100008 (The data buffer to receive returned data is too small for the returned data.
Here is my script:

I note that when I run it via JCShell everything works fine.
Can somebody help me to solve my problem? Any ideas?

Is there a data Buffer similar to Chart Histroy in LabView ?

Dear all,
Is there a data Buffer similar to Chart Histroy in LabView ? Which I can store a large amount of data without worrying about memory & overflow ? I don't want to display original data, I want to process data in the buffer, then discard the original data. Do I necessarily need to use Chart?
I don't want to display original data because I want to save time to do other processing and make output more "real-time".
Maybe " Initilize Array" can do that? any one has examples? or is there similar functions in Labview as " Malloc" in C/C++?

But one of the things that the Chart History buffer handles is to act like a circular buffer, overwriting old stale data as new data comes in. As far as I've been able to determine, Queues can't do that. Instead, a queue will either grow its size and write the new data into the new space or else it will ignore the new data and return an error. I haven't found an option that lets you leave the queue at the same size and overwrite the oldest data with the new data coming in.
In the past I've used LabVIEW RT where the RTFIFO offers such an option, and I don't understand why queues don't support it.  I'll grant that the default behavior for a queue should be NOT to overwrite, but an explicit option would be very useful.
Probably an even better wishlist item would be a new set of functions called Circular Buffer. Underneath, it could be implemented similarly to either Queues or RTFIFO's. Additional accessor functions would be provided to allow random access rather than purely sequential access.  The ability to request an array of elements rather than a single one at a time should also be supported.
In the meantime, someone on this forum posted a tip a few weeks ago. He (she?) would create a subvi that used an actual Waveform Chart as the circular buffer. The extra trick was to hide the chart on so there wouldn't be slowdowns to draw the chart data n the front panel.   Ah yes, see the response by rpursley8 in this thread.

SR830 data buffer

I'm using the LABVIEW driver for the SR830 lock-in amplifier and trying to use the data buffer, but I'm having a problem with it. The buffer seems to be recording the correct number of points, but it returns a 0 for all points greater than ~2880 (see the attached file). Does this sound like a problem with LABVIEW or the SR830?
Attachments:
throwaway3.txt ‏60 KB

I have used the SR830 buffer to its "full potential" without any problems; without seeing your program it is difficult to acertain the problem.
Try the program at the bottom of the following link, http://forums.ni.com/t5/LabVIEW/Can-driver-for-SR830-and-SR844-be-used-interchangeably/m-p/1702554#M... (The last entry in the discussion)
I wrote it for the SR830 and have used it without problems; I am no LabVIEW expert, but it may help you. Put context help on to read what the buttons do on the front panel.

How to view the returned data from a stored procedure in TOAD?

Hi,
I created ref cursor in the stored procedure to return data. The stored procedure works fine, just want to view the result in TOAD. The BEGIN... EXEC... END can execute the stored procedure, but how to make the result display?
Thanks!

Right click the editor and choose
"Prompt For Substitution Variables".
Run for example the following code:
DECLARE
PROCEDURE p (cur OUT sys_refcursor)
AS
BEGIN
OPEN cur FOR
SELECT *
FROM DUAL;
END p;
BEGIN
p (:cur);
END;
The result will display in Toad's Data Grid!

Can I return my MacBook Air past the return date?

Hi, I have a question that I've been googling but I haven't been able to find an answer to anywhere. Can I return a MacBook Air past the return date to an Apple store if it is still in shrink-wrap and I have a receipt? Thanks.

I would think you cannot return a product after the return date has passed.
Call the Apple Store and ask them.

Return data from all columns apart from a certain data type.

Bit stuck on something, hope somebody here can help:
I want to do a 'select * from ' a table, to return all columns except ones of a certain datatype. ie. I want to return data from all columns, excluding columns of datatype 'SDO_GEOMETRY'.
This gives me the list of columns:
SELECT COLUMN_NAME
FROM   USER_TAB_COLUMNS
WHERE TABLE_NAME = 'ORDER_ITEM'
AND   DATA_TYPE <> 'SDO_GEOMETRY'; But I can't seem to take it any further...
Now if I knew the columns beforehand, then of course I could just list them, excluding the geometry column, but this is to be used for a plug-in for MS Word, where a user can pick database columns to dynamically fill a report from - but I don't want the geometry columns as these can't be handled in this way.

Hi Reggie,
> connects to the database and presents a list of tables
My guess is that this macro is written so it selects from all_tab_cols.
Change that plugin and let it select from a view like the one above. That way, the users won't be able to see/pick anything that you are not able/willing to present for them.
Edit:
You could even tease your users, and let them see the columns, but not being able to pick them.
create or replace view available_tab_columns
as
   select decode(pickable.data_type, null, 0, 1) pickable
         ,atc.* -- narrow down yourself
     from all_tab_cols atc -- or maybe user_tab_cols
         ,(select 'CHAR' data_type from dual union all
           select 'DATE' from dual union all
        select 'NUMBER' from dual
           -- complete positive list, yourself
          ) pickable
    where atc.data_type = pickable.data_type(+);Regards

'Driver]Parameter missing' Error while trying to pass parameter to MS query & Return Data to Microsoft Excel

I am trying to set up a parameter query using ODBC-Microsoft Query
to BMC Remedy The ODBC connection is "AR System ODBC Data Source".
I want to pass a parameter to modified date field and get all the remedy tickets for which the modified date is<= to the passed parameter date.
So in MS query, SQL-
the query looks like
WHERE ("Trouble Ticket"."Create Date">={ts '2014-10-01 00:00:00'}) AND ("Trouble Ticket"."Modified-date"<=?)
I am getting the data fetched from database in the MS query window, but unfortunately
When I click File-Return Data to Microsoft Excel, its showing an error: Driver]Parameter missing
I set the connection properties- parameter-Prompt for value using the following string.
Please help

Hi,
Based on the error message, I recommend we try the suggestion: Replace all "..." with [...]
http://www.pcreview.co.uk/forums/error-parameter-query-odbc-remedy-bmc-software-com-t3232964.html
Then, if you want to connect the Remedy's oracle database, please see the thread:
http://www.tek-tips.com/viewthread.cfm?qid=1123112
We may try the workaround: Write an Excel macro which connects to the database and fetch the data based on the SQL query.
Please Note: Since the web site is not hosted by Microsoft, the link may change without notice. Microsoft does not guarantee the accuracy of this information.
If you have further question about write macro, I recommend you post the question to the MSDN forum for Excel

Query returns data from previous month. Need to have it return data for the entire year

This is the part of the query that returns data by month:
(YEAR(`rereport`.`market_reports_5`.start_date) = YEAR(CURRENT_DATE - INTERVAL 1 MONTH)AND MONTH(`rereport`.`market_reports_5`.start_date) = MONTH(CURRENT_DATE - INTERVAL 1 MONTH))
How can I get it to return data for the year.
TIY

How about omitting the MONTH part:
(YEAR(`rereport`.`market_reports_5`.start_date) = YEAR(CURRENT_DATE - INTERVAL 1 MONTH)

The ways to return data from a stored procedure.

Hi, I know there are three ways to pass out a value from a Microsoft SQL stored procedure, but I have no clear idea what Oracle SP can do, I know Oracle doesn't support multi-recordset(v8), can not return a recordset by a inner select query, but I do know there is a cursor object, which doesn't like its counterpart in Microsoft SQL server, is a choice under most situation. Here I wonder anyone who is good at Oracle can give a list of all ways to return data from a SP, including example is more better, thanks.

Here is a way to get return a record from a function and a procedure. You need to be familiar with Oracle packages as well as stored procedures and functions:
CREATE OR REPLACE PACKAGE EmpPkg AS
cursor cEmp(pEmpno in number) is
select empno, ename, job, hiredate, sal
from emp
where empno = pEmpno;
FUNCTION GetEmployee(pnEmpNo in number) RETURN cEmp%rowtype;
PROCEDURE GetEmployee(pnEmpNo in number, prEmp out cEmp%rowtype);
END;
CREATE OR REPLACE PACKAGE BODY EmpPkg AS
FUNCTION GetEmployee(pnEmpNo in number) RETURN cEmp%rowtype IS
rEmp cEmp%rowtype;
BEGIN
open cEmp(pnEmpNo);
fetch cEmp into rEmp;
close cEmp;
return rEmp;
END;
PROCEDURE GetEmployee(pnEmpNo in number, prEmp out cEmp%rowtype) IS
BEGIN
open cEmp(pnEmpNo);
fetch cEmp into prEmp;
close cEmp;
END;
END;
Here's how you use the package:
DECLARE
rEmp EmpPkg.cEmp%rowtype;
BEGIN
rEmp := EmpPkg.GetEmployee(7782);
dbms_output.put_line(rEmp.ename);
EmpPkg.GetEmployee(7902, rEmp);
dbms_output.put_line(rEmp.ename);
END;
Note that you can return any Oracle data type from a function. Likewise, you can specify any Oracle data type as an out parameter in a procedure. Also, you can make a parameter both an in and an out datatype like this:
PROCEDURE GetEmployee(pnEmpNo in out number);
I hope this puts you in the right direction.

Query in ASWE XML code doesn't return data

Hello, since people on the Oracle Metalink site are to lazy to give an answer to this question. I'll try it via this forum. Here we go:
I'm developing wireless applications running on Oracle9i Application Server Wireless Edition. I'v tried to implement the employee sample from Oracle Online Mobile Studio (studio.oraclemobile.com). The sample name is employee.jsp. This sample combines XML code with JSP.
(code at the end of the text)
When I test the sample I get no query results.
When you take the first option for example, (search by dept number) the query result will not be displayed. I think it has something to do with the "executeQuery" line.
rset = stmt.executeQuery("select * from EMP where EMPNO='" + empNum + "'");
After giving the following input (employeenumber) 7369 (which excists in the
database). I get the following errors:
The panama server log returns the following error:

Does this have something to do with the encoding of the query result in the select statement? As you can see the variable is in the requeststring (URL = http://host/portal/test/employee.jsp?&empNum=7369)
My database connection works fine (I've also tested the query using SQL plus and the SQL adapter also works).
Is this the right statement?: ("select * from EMP where EMPNO='" + empNum + "'");
I can not do anything with the error in the jserv.log (java.sql.SQLException: Invalid column name).
The columnname EMPNO excists in the example table. The query in SQL plus gives a result.
Can someone give my any suggestions?
Thanks in advance.

Is EMPNO really a string field and not a numeric field? Your query is like
... where EMPNO='1949'
and should it perhaps be
... where EMPNO=1949
?
