BSP query on output display

Hi All,
I have designed a basic BSP with 2 pages.one for the input and the output to be displayed on the second page.
In the first page i have the input fields and the button to transfer the control to the second page where the output will be displayed.
In my second page On Initialisation event I have written the selection of table based on my input.The internal table is filled correctly.
When the control goes to display(Layout) internal table contents gets cleared.I have declared the table in my page attributes also.Please let me know where am I going wrong?
Thanks in advance,
S.K.

Hi Marcin,
I tried your suggestion but no help.I am attaching my code which will help you to identify where I am going wrong.
First page On input processing:
data w_event type ref to cl_htmlb_event.
call METHOD cl_htmlb_manager=>get_event
EXPORTING
request     = runtime->server->request
RECEIVING
event       = w_event.
if w_event->id eq input_field'.
navigation->set_parameter( from_field).
navigation->set_parameter( to_field).
navigation->goto_page('second.htm').
navigation->next_page( 'NEXT').
endif.
Second page has initialization event
call METHOD cl_htmlb_manager=>get_data
EXPORTING
request = runtime->server->request
name = 'inputfield'
id   = from_field
RECEIVING
data = w_obj.
call METHOD cl_htmlb_manager=>get_data
EXPORTING
request = runtime->server->request
name = 'inputfield'
id   = to_field
RECEIVING
data = w_obj.
select * from table into table t_itab
where zteam between from_field AND to_field.
I have defined the table t_itab in the attributes with auto checked.
Pls advise if anythig to be changed.
Thank you.

Tell me where in this code i do mistake.
Thanks jayant.

I don't know the contents of the table, but if you increase the number of restrictions in the SELECT statement, it will probably have lesser entries.
Now, you are not really counting the total number of rows left in the table, but the total number of rows in the table that match the criterion.
Basically, the first time (with lesser options) 10 rows are put into internal table, and 2 are deleted. So 8 are left.
In the second time, only 4 rows are getting selected, of which 2 are deleted, and 2 are left in the internal table NOT in the database table. In the database table, more rows are left (because they never got selected into the itab)
But if you want to count the total number of rows left in the DB, its better to count the number of rows in the end of the program with:
SELECT COUNT(*) FROM dbtab INTO lv_integer.
This can be pretty slow if the table is huge.

Spool file problem,Can't see the query in output file.

Hello ,
I am facing a very old school kind of problem .....about spool file ....
The scenario -
I have made a script by name DB_Status_checkup.sql which i want to fire on the database to check the database status. In this script their are many queries regarding the data dictionary views to know about the database. It consist of nearly 25-30 different select queries..
The problem is i want to make a spool file of the output of that query....i want to see the SQL query & the output below in the spool file, so it will be easy for me to judge the result. But i can't see the SQL query , i can only see the output , & in so many queries it all gets jumbled up....even i can't understand where the next output starts ...
Sample of my SQL Script ....
clear buffer
spool D:\DB_status.txt
/*To check the database startup time*/
Select to_char(startup_time, 'HH24:MI DD-MON-YY') "Startup time"
from v$instance
.........next query n so on....
spool off;
In the output pf the spool file at D:\db_status.txt..
Startup time
08:25 16-JUL-10It shows only the output of the query in the spool file not the query,
What should i do to get the SQL query as well as the output of that query just below it in the spool file ???
Please suggest if you have anymore ideas , regarding this .....

Thanks in advance ...

Why don't you just use database control, instead of re-inventing the wheel?
Apart from that, SQL*Plus has it's own reference manual, which you apparently refuse to read.

How to redirect the output display on Ultra 5 box.

Hello,
Good day to you.
I have issues with redirecting display output to my console server (which is configured with cyclades switch) on a newly installed solaris 10, Ultra 5 box.
I could access the output display on the monitor when I connect it directly to the serial port. But I also have my parallel port connected to cyclades switch which is primarily being used for accessing multiple servers thro' one single console server.
When I try to access my ultra 5 box thro' console server, the display not getting redirected over there..I did checked the port from cyclades switch front, it did work well with other machines.
Looks like some work needs to be done at Ultra 5 box level so that the parallel port can send output signals to the respective port on cyclades switch and consequently to the console server.
Any thoughts ??
Thanks.

Hi,
Good day to you.
Apologize for quoting "Parallel" port. It is a in-built 25pin serial connector placed next to regular 15 pin serial port.
Just to make a point here, this 25 pin serial connector has an external converter attached with other side having RJ45 jack.
CAT5 cable connected between switch port to this RJ45 jack.
I did tested this converter with another machine and could able to access the display on my console server. So it seems to be the connectivity from serial port to switch port works fine.
Adding to that, this ultra 5 box with the current connectivity set up was working fine until I rebuild this machine. I was very well accessing this box thro my console server. There was no changes done except rebuilding the operating system.
I think some work needs to be done at the ultra 5 box level to get this 25pin serial connector to act.
Thanks.

Problem In report output display when i run in the background

Hi,
In a classical report i am printing around 17 fields the width of the report out put is around 800 characters.
If i run the report in the fore ground it running perfectly. But the thing is when i give large selection is it GETTING ' TIMED OUT ' as it is running more than an Hour.
so i wanted to run it in the back ground to avoid TIME OUT problems.
But when i run in the backgroud i am not getting full out put in the SPOOL request(SIZE of the report output may causing the problem) .
Pls come up with some solutions
Thanks in advance

Try increasing the spool length..
Refer this link for doing so.

Query in output of sh interface

Hi all,
I have a query in output of sh interface on ASA.
On ASA's when we do 'show interface' for a gig interface, we can get any among two,
input queue (blocks free curr/low): hardware (255/230)
output queue (blocks free curr/low): hardware (255/0)
OR
input queue (curr/max packets): hardware (0/7)
output queue (curr/max packets): hardware (0/13)
cur/low I suppose when we have underruns and overruns going on.
What i want to know is the meaning of the output. In case of curr/max its very clear.
input queue (curr/max packets): hardware (0/7)
output queue (curr/max packets): hardware (0/13)
Above means (correct me if I am incorrect), there are Zero packets currently in input queue, and 7 were the max packets seen at one time. For output queue, zero are the current packets in ouput queue and 13 were max that were seen in output queue. This is documented.
But I could not find an explaination for,
input queue (blocks free curr/low): hardware (255/230)
output queue (blocks free curr/low): hardware (255/0)
How should I interpret it? I need supporting documentaion please.
I have gone through this link :
http://www.cisco.com/en/US/docs/security/asa/asa84/command/reference/s3.html#wp1497263
But i couldn't find an explanation for blocks free current/low
Please explain me the following output:
2506116 packets input, 2624544574 bytes, 0 no buffer
       Received 0 broadcasts, 0 runts, 0 giants
       8036 input errors, 0 CRC, 0 frame, 8036 overrun, 0 ignored, 0 abort
       0 L2 decode drops
       5065834 packets output, 6024814558 bytes, 0 underruns
       0 pause output, 0 resume output
       0 output errors, 0 collisions, 0 interface resets
       0 late collisions, 0 deferred
       0 input reset drops, 0 output reset drops, 0 tx hangs
       input queue (blocks free curr/low): hardware (255/230)
       output queue (blocks free curr/low): hardware (254/0)

i am mainly concerned about
input queue (blocks free curr/low): hardware (255/230)
       output queue (blocks free curr/low): hardware (254/0)

Extending Expert Query VO but Query doesn't display in standard VO

I need to add a new attribute to an export query VO (oracle.apps.icx.por.reqmgmt.server.GroupReqsPublicVO), but when I edit the standard VO in JDeveloper the existing query doesn't display (query is blank and no attributes are listed). I can get the query from the xml file, but does this mean there is a problem? Should I just copy the query from the xml file and use that?

All of the info is in the standard VO xml file (ie query, attributes, etc), but when I choose Edit VO ... in JDev nothing is displayed. A similar standard VO (slightly different query) appears fine in JDev - query and attributes displayed.
I ended up trying the following, which appears to be working (although I am still waiting on some test data from the users):
Create new VO, extending standard
Copied the query from standard VO xml file
This left me with all of the queried attributes, but none of the transient attributes.
I tried to copy the additional attributes from the standard VO xml file to the extending VO xml file in JDev, but the extending VO xml file is protected.
Then I closed JDev, manually edited the extending VO xml file to include the additional transient attributes that are in the standard VO xml file.
Whether it was related or not, but when rebuilding my project, it complained that it couldn't find the standard VO's Impl java file, so I decompiled the class file to produce that.

BEx Query Analyzer Value Display of +/- Sign

The KeyFigure values in the BEx Analyzer are being displayed as 512.740000000- with a negative sign in the back. I tried to change the settings in Bex Query Designer -- Query Properties -- Value Display to "Before the Number -123.45" setting. It looks like it doesn't have any effect.
Please let me know if I need to change the setting from the backend, we are on BI 7.0.

It should work. Try to refresh the query if not come out of Bex and Relogin. This should fix

Auto Query in Before Display Page Section

The following code is querying master and detail blocks automatically in before display page section. It was working fine. But now I don't know why it doesn't work any more. Does any one know what's the problem?
declare

l_s varchar2(4000);
L_user varchar2(4000);
begin
l_fs := p_session.get_value_as_varchar2(p_block_name => 'MASTER_BLOCK',
p_attribute_name => '_FORM_STATE');
l_s := p_session.get_value_as_varchar2(p_block_name => 'MASTER_BLOCK',
p_attribute_name => '_STATUS');
L_user := portal30.wwctx_api.get_user;
if l_fs = 'QUERY_AND_SAVE' and l_s is null then
p_session.set_shadow_value(p_block_name => 'MASTER_BLOCK',

end if;
end;

Hi,
To query records before displaying and to refresh the page, you can call the same form (by using the code given below)with necessary parameters from ..before displaying page..section of your form.
declare
l_fs varchar2(4000);
l_s varchar2(4000);
L_user varchar2(4000);
begin
l_fs := p_session.get_value_as_varchar2(p_block_name => 'MASTER_BLOCK',
p_attribute_name => '_FORM_STATE');
l_s := p_session.get_value_as_varchar2(p_block_name => 'MASTER_BLOCK',
p_attribute_name => '_STATUS');
L_user := 'PPP';
if l_fs = 'QUERY_AND_SAVE' and l_s is null then
htp.p('<SCRIPT LANGUAGE="JavaScript">
window.location.href = "PORTAL30.wwa_app_module.link?p_arg_names=_moduleid&p_arg_values=<MODULE ID>&p_arg_names=_show_header&p_arg_values=YES&p_arg_names=E_MAIL_ID&p_arg_values='||l_user||'&p_arg_names=_E_MAIL_ID_COND&p_arg_values=%3D";
</script>');
end if;
end;
Replace <MODULE ID< with the module id of your master detail form.
Hope this helps!..

Parametrized query with output from sql

Hey all,
has anyone figure out how to use the database connectivity toolset to perform a parameterized query with outputs (SQL)? From the other threads that i have read it would seem that this issue is not resolved. The error i get is:
Error -2147467259 occurred at Cmd Execute.vi->getjobID.vi
Possible reason(s):
Exception occured in Microsoft OLE DB Provider for ODBC Drivers: [MySQL][ODBC 3.51 Driver][mysqld-5.0.50sp1a-enterprise-gpl-log]OUT or INOUT argument 3 for routine eln.lv_caperJob_create is not a variable or NEW pseudo-variable in BEFORE trigger in Rec Create - Command.vi->Cmd Execute.vi->getjobID.vi
However, In Toad for mysql the following call works:
set @outJobID=-999;
set @outMsg="";
call lv_caperJob_create('TestJune30_2', '207', @outJobID, @outMsg);
select @outJobID, @outMsg
Attached is the LV code i am using. Thanks!

Your first approach gave you an error because it took the ? parameter inside the '%?%' string and treated it as whole string as '%?%'. As you set the parameter, it did not understood where it need to insert the parameter.
Your second approach is pretty much OK, only problem is you are trying to set the parameter with a string and aging creating the string while setting the parameter.
The solution will be to create the whole string before setting the parameter and set the created String as parameter on the query something like this.
String parameter = "%"+searchString+"%";
Then set the parameter string to the query.
Thanks
