ProC: RAISE_APPLICATION_ERROR
In procedure builder, I can use RAISE_APPLICATION_ERROR. However when I try to use it in ProC, my code will not compile. Why? Is there a work around?
Try:
EXEC SQL WHENEVER SQLERROR DO your_err_function();
EXEC SQL WHENEVER SQLWARNING DO your_warning_function();

Oracle proc call from CF has 4sec overhead
G'day
I've been troubleshooting a slow-running Oracle (9i)
proecdure call, which
was coming in at 4sec. When run via a Oracle SQL Developer
window, it runs
in 0ms, which is more like what I'd expect form the amount of
work it's
doing.
I applied FusionReactor to the situation, and it's reporting
that the proc
is indeed *running* in 0ms, but the added overhead of CF
calling it is
4sec. From the "Longest JDBC" screen, the figures were:
Total Time(ms): 3845
DB Time(ms): 0
What on earth is CF doing?
Notes:
- it's returning zero rows, so it's not a data-transmission
overhead.
- the DB is running on the same box as CF.
- it's not a one-off. Running the proc with different input
data (which
would yield any number of rows returned from 0 to 30000-odd)
seems to make
little difference. The DB side of things runs between
0-100ms, and then
there's close to a 4sec overhead added by CF.
The stored proc is running a couple of select queries (a
value from the
first contributing to the second), and returning a single
resultant record
set. Nothing complicated.
Any ideas?
Adam> Is the problem with a single SP, or set of SPs, or all
of your proc calls? If
It was happening on more than just that one, but it's the one
that's called
the most frequently, so sticks out more. I'm offsite @
present so can't
check more thoroughly if it's that package, or all, some, or
what. I'll
check tomorrow.

Yeah, I thought about that: it's usually the first thing I
say when
someone's asking for help too "it's a bit bloody hard to tell
what's going
on... etc".
If it was just a "why's my query / proc runnning slow on CF:
it runs fine
when I run it in query analyser" I'd agree that seeing that
stuff would
make sense. However monitoring the JDBC connection I can
*see* that the
proc is running fine: the DB server is reporting to the JDBC
driver that
it's taking 0ms to run. It's just the comms from the driver
to CF (or
vice-versa) that's killing the time.
I dunno if this code will help you @ all, without seeing
really a lot of
the rest of the underlying code, but... 'ere 'tis.

hi
i have stored proc like this
ALTER PROCEDURE [dbo].[p_member]
@MemberID INT = NULL,
@ID INT = NULL,
@Type varchar(20) = NULL
AS
IF NOT EXISTS (SELECT Memberid FROM Member mcd JOIN Pro p WITH(NOLOCK)
on mcd.ProgramID = p.ProgramID WHERE ((mcd.MemberID = @MemberID) OR (mcd.ID = @ID and p.CD = @Type)))
BEGIN
select 'CAN''T BE FOUND'
END
i am not sure what i am doing in if statement, its not working.my logic should be like
check if atleast on or the other is available ..ie memberid or id+type, if nto i need to print message.
thanksWhat do you get for the following:
DECLARE @MemberID INT = 444,
@ID INT = NULL,
@Type varchar(20) = NULL;
IF NOT EXISTS (SELECT Memberid FROM Member mcd JOIN Pro p WITH(NOLOCK)
on mcd.ProgramID = p.ProgramID WHERE ((mcd.MemberID = @MemberID) OR (mcd.ID = @ID and p.CD = @Type)))

** How to use TO_DATE function in Stored Proc. for JDBC in ABAP-XSL mapping
Hi friends,
I use ABAP-XSL mapping to insert records in Oracle table. My Sender is File and receiver is JDBC. We use Oracle 10g database. All fields in table are VARCHAR2 except one field; this is having type 'DATE'.
I use Stored procedure to update the records in table. I have converted my string into date using the Oracle TO_DATE function. But, when I use this format, it throws an error in the Receiver CC. (But, the message is processed successfully in SXMB_MONI).
The input format I formed like below:
<X_EMP_START_DT hasQuot="No" isInput="1" type="DATE">
Value in Payload is like below.
<X_EMP_START_DT hasQuot="No" isInput="1" type="DATE">TO_DATE('18-11-1991','DD-MM-YYYY')</X_EMP_START_DT>
Error in CC comes as below:
Error processing request in sax parser: Error when executing statement for table/stored proc. 'SP_EMP_DETAILS' (structure 'STATEMENT'): java.lang.NumberFormatException: For input string: "TO_DATE('18"
Friends, I have tried, but unable to find the correct solution to insert.
Kindly help me to solve this issue.
Kind Regards,
Jegathees P.
(But, the same is working fine if we use direct method in ABAP-XSL ie. not thru Stored Procedure)Hi Sinha,
Thanks for your reply.
I used the syntax
<xsl:call-template name="date:format-date">
<xsl:with-param name="date-time" select="string" />
<xsl:with-param name="pattern" select="string" />
</xsl:call-template>
in my Abap XSL. But, its not working correctly. The problem is 'href' function to import "date.xsl" in my XSLT is not able to do that. The system throws an error. Moreover, it is not able to write the command 'extension-element-prefixes' in my <xsl:stylesheet namespace>
May be I am not able to understand how to use this.
Anyway, I solved this problem by handling date conversion inside Oracle Stored Procedure. Now, its working fine.
Thank you. -
Replacing null values in optional prompts and passing to stored proc
Hi,
I want to create a stored procedure with OPTIONAL prompts. When user does not pass a value for that parameter, I want to set the value for that parameter by selecting from a column in table then I WANT to use that paramvalue in sql within cursor of stored proc. How do I do that?
In short, I want to do the following Here is the psuedocode:
Create or replace procedure test (param IN varchar2 DEFAULT NULL)
As
var_param varchar(20);
select param into var_param from dual;
If param is null then select custid from table1 else var_param
OPen ref_cursor for
Select xyz from table2
where fyy = var_para
Can someone let me know the syntax on how to do this in stored proc?
Regards,
hena
Edited by: 904385 on Dec 25, 2011 7:04 AMHi,
Merry Christmas, and welcome to the forum!
Here's one way to do what you requested:
CREATE OR REPLACE PROCEDURE test
( param IN VARCHAR2 DEFAULT NULL
AS
ref_cursor SYS_REFCURSOR;
var_param VARCHAR2 (20) := param;
BEGIN
IF var_param IS NULL
THEN
SELECT custid
INTO var_param
FROM table1
-- WHERE ... -- Unless table1 has only 1 row
END IF;
OPEN ref_cursor
FOR SELECT xyz
FROM table2
WHERE fyy = var_param;
END test;Whatever you're trying to do, this is probably niot the simplest or most efficient way to do it. -
Which Mac Pro? More cores=slower speeds? And most of us know the speed matters or FPU for music and I don't understand the faster is for the least amount of procs. And while I get the whole rendering thing and why it makes sense.
The above is what the bar says. It's been a while and wondered, maybe Apple changed the format for forums. Then got this nice big blank canvas to air my concerns. Went to school for Computer Science, BSEE, even worked at Analog Devices in Newton Massachusetts, where they make something for apple.
The bottom line is fast CPU = more FPU = more headroom and still can't figure out why the more cores= the slower it gets unless it's to get us in to a 6 core then come out with faster cores down the road or a newer Mac that uses the GPU. Also. Few. I'm the guy who said a few years ago Mac has an FCP that looks like iMovie on Steroids. Having said that I called the campus one day to ask them something and while I used to work for Apple, I think she thought I still did as she asked me, "HOW ARE THE 32 CORES/1DYE COMING ALONG? Not wanting to embarrass her I said fine, fine and then hung up. Makes the most sense as I never quite got the 2,6,12 cores when for years everything from memory to CPU's have been, in sets of 2 to the 2nd power. 2,4,8,16,32,64,120,256,512, 1024, 2048,4196,8192, 72,768. Wow. W-O-W and will be using whatever I get with Apollo Quad.
Peace to all and hope someone can point us in THE RIGHT DIRECTION. THANK YOUThanks for your reply via email/msg. He wrote:

I read that the CPU is easy to swap out but am sure something goes wrong at a certain point - even if solderedon they make material to absorb the solder, making your work area VERY clean.
My Question now is this, get an 8 core, then replace with 2 3.7 QUAD CHIPS, what would happen?
I also noticed that the 8 core Mac Pro is 3.0 when in fact they do have a 3.4 8 core chip, so 2 =16? Or if correct, wouldn't you be able to replace a QUAD CHIP WITH THAT?

SOMETHINGS UP AND AM SURE WE'LL ALL BE PLEASED, AS the mac pro was announced Last year, barely made the December mark, then pushed to January, then February and now April.
Would rather wait and have it done correct than released to early only to have it benchmarked in audio and found to be slower in a few areas- - - the logical part of my brain is wondering what else I would have to swap out as I am sure it would run, and fine for a while, then, poof....
PEACE===AM SURE APPLE WILL BLOW US AWAY - they have to figure out how to increase the power for 150 watts or make the GPU work which in regard to FPU, I thought was NVIDIA? -

Basically I will be calling a PL/SQL api from AM . So here I need to pass SYSDATE in milliseconds as one of the PL/SQL proc parameters.
How do you I go about this ?
Any help is aprreciated.
Thanks in Advanceget the current database date by

Now you may convert this currentDate to java date object.

Concurrent HOST program calling a proc to log using fnd_file.put_line
Hello all,
I have a concurrent HOST program that does 3 main things
1. Calls a sqlplus program to do some initializing. This program is a proc in a package.
2. Runs sqlldr to load data to custom tables.
3. Calls a sqlplus program to do manipulate the data. This program is a proc in a package.
In step 3 of above, the package procedue does a "submit_request" to call the "Supplier Open Interface Import". This
request actually fires. However my problem is the subsequent call to fnd_file.put_line(fnd_file.log, 'Test message'), does not get logged
to the log file of the HOST program, nor to the log file of the "Supplier Open Interfface Import" log file. A check
of $APPLPTMP (or /usr/tmp) shows that a file of say " l0023761.tmp" contains my 'Test message' text.
I believe the problem is that the put_line() call has no association with the HOST or the "Supplier Open Interface Import. How
do I associate the logging to either program? Is it even possible? I want the logging, so as to see the progress
of the HOST program.
The sniippet of proc code is:
PROCEDURE abc() IS
BEGIN
request_id:= FND_REQUEST.SUBMIT_REQUEST
(Application => 'SQLAP'
,Program => 'APXSUIMP'
,Description => NULL
,Start_time => SYSDATE
,Sub_Request => FALSE
,Argument1 => 'ALL'
,Argument2 => 1000
,Argument3 => 'N'
,Argument4 => 'N'
,Argument5 => 'N'
fnd_file.put_line (fnd_file.log,'Test message');
COMMIT;
END abc;
Alex.Shell scripts are very hard to develop and maintain. Many things that developers previously had to do in shell scripts, developers can now do in PL/SQL. Hence, I recommend that you avoid shell scripts as much as possible.
As well, SQL*Loader is an old, inflexible tool. Instead, define your OS file as an external table, and then extract from the external table using a normal select statement. http://www.orafaq.com/node/848 I recommend that you avoid SQL*Loader and use external tables instead.
Using PL/SQL and external tables - and avoiding the shell script and SQL*Loader - a much better way to accomplish the same thing all inside one packaged procedure that is registered as a concurrent program:
- initialize
- select from the external table
- manipulate the data -

So, I have noticed that, Where ever a STRUCTURE is involved in external routine, there is a problem. I want to know, How to implement functions with STRUCTURE as OUT parameter.
Forgot to mention: This is my FILETIME object which corresponds to FILETIME structure of win32.The problem is that this passes the parameter by reference and not value. In a vanilla C/C++/Delphi program, you will create a variable of that struct and then pass a long pointer to that variable when making the API call. That pointer will be dereferenced and the memory it points to, populated. This is not a problem as the underlying DLL you call that does this, uses your process's data segment.
Extproc is different. In order to protect the integrity of the database server process, an external call is done by a "proxy" process. It acts as the interface between your PL/SQL code and the actual external call.
In this case, this "proxy" process will be doing the implicit LoadLibrary() call to load kernel32.dll interface - and the DLL will expect to dereference and access this process's memory struct to populate it. This "proxy" process in turn needs to know that despite it calling the interface by reference, it needs to return that parameter to PL/SQL by value - as your PL/SQL code cannot dereference a pointer passed back by that "proxy" process and access its memory to gain access to that struct.
In basic terms - that argument is a 32 bit number containing a pointer. That is what the "proxy" process needs to pass to the interface call. Your code is passing a struct and not a pointer, right?
And that is the basic problem I believe. How to address this.. not sure. You can have your own DLL as interface that does not use pointers but expect arguments to be passed by value. But this will suck as you then need to include a custom DLL to deploy and have PL/SQL call that, instead of simply accessing and calling the native kernel interface.
Doubt that many Win32 programmers with OCI (Oracle Call Interface) frequents this forum. So perhaps this is not the best place to ask. I would be hitting Metalink (support.oracle.com) search function in your sho3s though as there should be support notes dealing with this subject matter. -
Oracle Proc in edmx via add function import is not working
I have a mandate to call a external oracle package from my local oracle db proc using Entity Framework. I have created a synonym for that. When I am trying to polpulate the oracle procedure data in my mvc screen using odp.net. The screen is closing automatically when I am trying to retive the column info by clicking "get column information" under "Add Function Import" in model browser.
Following is my code snipet
1. created a oracle stored proc to call the external proc
CREATE OR REPLACE PROCEDURE USP_GET_DETAILS
IN_ID IN NUMBER,
OUT_RESULT OUT SYS_REFCURSOR
IS
OUT_FED_TAX_ID_NO VARCHAR2(50);
OUT_PARTY_ID_NO NUMBER;
OUT_PARTY_TYP_CD NUMBER;
BEGIN
PKG_GET_DETAILS.USP_GET_DETAILS_INFO (IN_ID, OUT_FED_TAX_ID_NO, OUT_PARTY_ID_NO);
OPEN OUT_RESULT FOR
SELECT OUT_FED_TAX_ID_NO, OUT_PARTY_ID_NO FROM DUAL;
END USP_GET_DETAILS;
2. added the proc "USP_GET_DETAILS" using "Update model using database" in my edmx file
3. Now proc has been added to my edmx file under SSDL
<Function Name="USP_GET_DETAILS" Aggregate="false" BuiltIn="false" NiladicFunction="false" IsComposable="false" ParameterTypeSemantics="AllowImplicitConversion" Schema="BCS_OWNER">
<Parameter Name="IN_ID" Type="number" Mode="In" />
</Function>
4. added following code to my web.config file
<oracle.dataaccess.client>
<settings>
<add name="BCS_OWNER.USP_GET_DETAILS.RefCursor.OUT_RESULT" value="implicitRefCursor bindinfo='mode=Output'" />
<add name="BCS_OWNER.USP_GET_DETAILS.RefCursorMetaData.OUT_RESULT.Column.0" value="implicitRefCursor metadata='ColumnName=OUT_FED_TAX_ID_NO;NATIVEDATATYPE=Varchar2;ProviderType=Varchar2'" />
<add name="BCS_OWNER.USP_GET_DETAILS.RefCursorMetaData.OUT_RESULT.Column.1" value="implicitRefCursor metadata='ColumnName=OUT_PARTY_ID_NO;NATIVEDATATYPE=Number;ProviderType=Decimal'" />
</settings>
</oracle.dataaccess.client>
5. underModel Browser try to add the procedure under "Add Import Function", select "Complex Type". when i am clicking on "Get column information" button, the screen blank for some time and then auto closing the screen without displaying any column info. I would like to know if any thing wrong i am doing on my steps? please help?I managed to workaround this problem.
I add the function with no return value. Then in the Model Explorer you go to the properties of the imported function and edit the return type property, the same dialog appears, but this time it works as expected(considering you have set all the values correctly on your config file). -
Returning both raise_application_error and return value from db function...
Hi ,
I use Oracle 10g and forms10g.
I have written a db packaged function such as:
function fnc_ipologismos_xiliometron(code_poleis_apo_var in varchar2,code_poleis_pros_var in varchar2)
return number
is
apostasi_var ref_apostaseis_poleon.apostasi%type;
onomasia_pol_apo_var ref_poleis.onomasia%type;
onomasia_pol_pros_var ref_poleis.onomasia%type;
begin
begin
select onomasia into onomasia_pol_apo_var
from ref_poleis
where code_poleis=code_poleis_apo_var;
end;
begin
select onomasia into onomasia_pol_pros_var
from ref_poleis
where code_poleis=code_poleis_pros_var;
end;
begin
select apostasi into apostasi_var
from ref_apostaseis_poleon
where code_poleis_apo=code_poleis_apo_var and code_poleis_pros=code_poleis_pros_var;
exception
when no_data_found
then
apostasi_var:=0;
return apostasi_var;
raise_application_error(-20015,'a message');
--return apostasi_var;
end; return apostasi_var;
end;The problem is that when the exception written above (in bold) returns 0 and exits the function.... whereas i want this value to be returned as well as the message in the raise_application_error....
I call this function in WHEN-VALIDATE-ITEM of a block item... such as:
if pkg_mod3_general.fnc_ipologismos_xiliometron
(:mod3_entoli_metakinisis.code_poleis_apo_type_id,:mod3_entoli_metakinisis.code_poleis_type_id)=0
and :mod3_entoli_metakinisis.seq_code_meso_metakin_type_id=2
then
raise form_trigger_failure;
end if; When the above condition is true then no message is displayed and the cursor sticks to the item(as the raise_application_error in the db packaged function is after the exit of the function) and when the condition is false then no message is displayed again ... as expected.....
How is it get the desired result.....- get the message from the raise_application_error and the function returns 0.....?????
Many thanks,
Simonyou cannot RETURN and RAISE a function.
RETURN ends the function immediately
RAISE ends the program unit and jumps in the EXCEPTION-Handler, if it exists. Else the function ends
