Result of the Explain SQL function database-specific ?
Hello, gurus...
I'm not able to find the "secondary index" information in ST05 + Explain.
Is the Explain SQL function database-specific ?
We're running SAP ECC 6.0 on a MSSQL database....
Please advice.
Is the Explain SQL function database-specific ?
yes it is. It must be database specific because it shows what the database is doing.
But also MSSQL shows you the index information.
Check the Explain, and search for clustered index seek, behind you will something like
tablename1, telling you that the first index was used. Primary index is tablename0.

Help w/MaxDB Function; also: how does the "Debug SQL" function work?
Hi there forum folks,
In my former life, I was a Basis guy, but I haven't had the pleasure of working directly with SAP applications in a few months. My current project is to attempt to use MaxDB in a real estate environment. We're tracking home listings so that we can build statistical reports... such as "what agents are in the Top 100 in postal code X?"
Anyway, as part of this project, I have attempted to construct my very first MaxDB database function. Unfortunately, it doesn't give me the answers I'm hoping to see. Here's the function:
CREATE FUNCTION COUNT_LISTINGS (AGENTID CHAR(10)) RETURNS FIXED(6,1) AS
VAR COLISTINGAGENTID CHAR(10);
LISTINGAGENTID CHAR(10);
MLSNUMBER CHAR(7);
UNITS FIXED(6,1);
SET UNITS = 0;
DECLARE FUNCTIONRESULT CURSOR FOR
SELECT MLSNUMBER,
LISTINGAGENTID,
COLISTINGAGENTID FROM FREDDIE.GLAR_SOLDS
WHERE LISTINGAGENTID = :agentid OR COLISTINGAGENTID = :agentid;
IF $COUNT IS NULL THEN
BEGIN
CLOSE FUNCTIONRESULT;
RETURN UNITS;
END
ELSE
SET $RC = 0;
WHILE $RC = 0 DO BEGIN
FETCH FUNCTIONRESULT INTO :mlsnumber, :listingagentid, :colistingagentid;
IF ( LISTINGAGENTID = AGENTID AND COLISTINGAGENTID IS NULL ) OR
( COLISTINGAGENTID = AGENTID AND LISTINGAGENTID IS NULL ) THEN
SET UNITS = UNITS + 1
ELSE
SET UNITS = UNITS + 0.5;
END;
CLOSE FUNCTIONRESULT;
RETURN UNITS;
I've tried to follow the official MaxDB documentation. My first deviation from that standard was the use of the "$COUNT" variable (instead of the "$RC" variable) immediately after the DECLARE/SELECT statement above. When I tried to use $RC, for either a successful or unsuccessful query, $RC was always set to a non-zero value.
I believe I'm past that, but now my issue is down around that FETCH statement. The UNITS variable doesn't end up with the value I expect. I know that it can be terribly confusing to try to analyze someone else's logic, but here's a brief narrative that describes what I'm trying to do...
The GLAR_SOLDS table holds one line for each home sold. It's keyed by the MLSnumber. Each record also stores up to four agents who've been involved in the transaction: the listing agent, the co-listing agent, the selling agent, and the co-selling agent. The database function I've written above pertains to the listing side only. If I can get this to work, a separate function will process the selling side. If no co-listing agent is involved in a given sell, that agent should get credit for 1 unit sold. If he/she has help from a co-listing agent, the agent should only get credit for 1/2 unit sold.
Also, does anyone know how the "Debug SQL" functionality is supposed to work within Database Studio? When I right-mouse click on my function, and follow the path thru "Debug As...", after entering the connection & function arguments, I'm presented with an empty screen. If you could point me to some documentation somewhere, I'd gratefully read it.
I'm using MaxDB 7.7.06.09 on Windows XP (WIN32) with MaxDB Database Studio 7.7.06.09 (build 009-123-202-944).
Thanks everyone for your help & advice.
~FredFred,
please either provide the full SQL statements for your example or stick with mine.
I'm not going to build it up myself a second time to suit yours now.
> But now, my issue is how do I store the resultant data in its own table?
So where is the problem?
INSERT INTO <target table> (field 1, field 2, ...) (<your query>) UDPATE DUPLICATES-
With my tables this looks like this:
create table sell_result (list_agent varchar(20) primary key, SUM_CREDIT fixed (10,2))
insert
into sell_result (list_agent,sum_credit)
( select list_agent, sum (credit) as SUM_CREDIT
from ( select sh.object_id,lag.name as list_agent, 1 as credit
from soldhomes sh join agents lag on lag.id = sh.list_agent_id
union all
select sh.object_id, lag.name as list_coagent, 0.5 as credit
from soldhomes sh join agents lag on lag.id = sh.list_coagent_id
group by list_agent
update duplicates
Check what we have now
sqlcli db770=> select * from sell_result
| LIST_AGENT | SUM_CREDIT |
| -------------------- | ----------------- |
| Lars | 4.50 |
| Lisa | 3.00 |
| Mona | 2.50 |
| Paul | 2.50 |
4 rows selected (600 usec)
Now add some sales data...
Insert into soldhomes values (11, 1, 2, NULL, NULL)
Insert into soldhomes values (12, 2, NULL, NULL, NULL)
Insert into soldhomes values (13, 2, NULL, NULL, NULL)
Re-run the INSERT command and you're done:
sqlcli db770=> select * from sell_result
| LIST_AGENT | SUM_CREDIT |
| -------------------- | ----------------- |
| Lars | 5.50 |
| Lisa | 3.00 |
| Mona | 5.00 |
| Paul | 2.50 |
4 rows selected (390 usec)
Neat, isn't it? -
Need to pass value from check box to the pl/sql function in process
My requirement is to use single value check box and pass the flag value to the pl/sql function.
The function need to interpret the flag and execute accordingly.
In this case checkbox name is P1_DELETE and it returns Delete, if checked.
Anonymous block with in the process looks as follows:
declare
l_result VARCHAR2(1024);
begin
l_result := test_function(:P1_DELETE);
end;Hi Visu,
checkboxes in APEX are handled as arrays, namely APEX_APPLICATION_GLOBAL.VC_ARR2. To pass and process the checked values of checkboxes in a pl/sql function or procedure you could use the following way, assuming you have a checkbox named P1_DELETE with a single return value of "Delete"
DECLARE
l_checkbox_values apex_application_global.vc_arr2;
BEGIN
l_checkbox := :P1_DELETE;
-- calling function test_function processing the value
test_function(NVL(l_checkbox(1), 'SOME_OTHER_VALUE'));
END;If the checkbox is not checked then the array at position 1 is null and you have to process that as you like.
If your checkbox would be a group than the array would be colon separated such as 1:2:3:4 etc. and you would have to loop the array like:
FOR idx IN 1..l_checkbox.COUNT LOOP
test_function(l_checkbox(idx));
END LOOP;Hope that helps.

I want to know if you have seen this scenario earlier?
Basically, the case statement in the logical sql is not getting executed correctly in the physical sql. Also,I see a SAWWITH0 in the query. Have you seen this before.
If you have any inputs on how to fix this, please share.
Thanks in advance.
-Mayank SharmaHello,
This is the logical and physical query that I am getting now.
My question is that, why am I not seeing the division operator (/) anywhere in the physical query. I am worried that the physical query is not being executed correctly.

The troubles with creating SQL function in Java
Hi!
I use Oracle 10g and connect to it from Java application. I need in creating SQL functions from Java code.
In Java I have:
Statement stm = null; try{ stm = dbConnection.createStatement(); stm.executeUpdate( query ); }catch(SQLException ex){ throw ex; }finally{ try{ stm.close(); }catch(Exception ex){ stm.close(); } }
And I'm passing the next SQL function:
create or replace function get_me return number is
result number;
begin
select 5 into result from dual;
return result;
end;
This code is run successful, but I can't call this funtion, because it has status Invalid
I'm looked the next error: PLS-00103: Encountered the symbol "" when expecting one of the following: . @ % ; is authid as cluster order using external character deterministic parallel_enable pipelined aggregate
But I don't understand, What the matter? From Oracle Enterprise Manager I can create this function without problems. So, I wrote the wong Java code. Also, I can't find my error :(
May be, do u have the some ideas?
Thank you very much!Post the whole pl/sql code please.
To run PL/SQL from within java you'll need callablestatement.
[here |http://www.idevelopment.info/data/Programming/java/jdbc/PLSQL_and_JDBC/CallPLSQLFunc.java] an example : http://www.idevelopment.info/data/Programming/java/jdbc/PLSQL_and_JDBC/CallPLSQLFunc.java -
Get result from PL/SQL function through XDBUri (10g)
Hi!
I have to call a PL/SQL function that takes two parameters and return one parameter. (I will do this from Oracle Service Bus).
It is possible to get relational data as xml through an XDBUri type over http by using the XML DB functionality. But is it possible to get the result of a PL/SQL function as XML as well?
I have tried to wrap the PL/SQL procedure inside a view, but cant get the variable to be bound into the sql.
I have tried with stuff like this:
create or replace view test (a, b)
as
select function(a, b) from dual
But since I dont have a table returning the values i cant get it work.
If I can make this view, I can call it through the XDMUri type.
Sombody that can help me to manage this?

Unable to retreive the return value of pl/sql function using DB Adapter
Dear Experts,
I am using DB Adapter in my BPEL Process. Using DB Adapter I am invoking a PL / SQL function. I am able to send two input parameters for the pl/sql function. But I dont know how to retrieve the return value from the function. Please suggest me.
Thanks,
RajeshYes I am returning a value from PL/SQL function.
Please see the code segments below,
FUNCTION "TD_INSERT" (a TDINIT_TYPE, stops TDDETAIL_TABLE )
RETURN VARCHAR2
AS
td_no Number;
td_id Number;
stop TDDETAILFULL_TYPE;
length number;
BEGIN
insert into TD_INIT values( ----passing all the values here --------- );
select max(tdno) into td_no from TD_INIT ;
length := stops.count;
for i in 1.. length loop
stop := stops(i);
insert into TD_DETAIL_FULL values(
td_no, ------- );
end loop;
commit;
RETURN td_no;
END;
Thanks,

Return the two values in PL/SQL function
Hi,
How to create the PL/SQL function to return two values based on arguments?
Can anyone suggest me the idea?
TIA,Dhiva wrote:

That thing can be a scalar value (single value). Such as date, number or string. E.g.

Extracting data of data type 'real' from the sql server database
Hi,
In my job, my source is a sql server database.
I am connecting to the source sql server database using ODBC (sqlserver driver) in the datastore.
In one of my source tables i have a field of data type real.If one of the value is 3.45678 , data services brings it in as 3.456780, which is OK, but if the real value is 4.7 in source, data services brings it as 4.699997. I want it to be brought in as 4.700000 and not as 4.699997(i.e it is expanding upto 6 digits after the decimal point).
Is this a default behavior of how data services reads the 'real' data types or is it because of how the ODBC sql server driver reads the data ?
Is the above problem connected to an option in the DS.config file called
LAZY_DECIMAL_CONVERSION which is set as true in our file.Should i set as false and will it solve this problem?
Thanks in Advance.I tried reproducing your case, I read a value with real datatype from sql server DB. For me the values are coming fine, 4.7 is read as 4.700000 or 4.528 as 4.528000. I have also checked the value of LAZY_DECIMAL_CONVERSION, it is true. So I dont think it is a problem with that being set to true. Try something out with the Column properties in Query transform.
I am using DS 3.2/ SQLSERVER 2008.

Problem with empty report parameters when passed to PL/SQL function
Hi,
We have come across what appears to be a bug in the JRC. When passing a report parameter to a PL/SQL function as a parameter, empty parameters are changed before being sent to the function. More specifically, an empty string "" ends up as the value "(')" in the PL/SQL function parameter. In our report we print the report parameters on the first page so we know that the parameters are OK before being passed to the database.
The problem exists for version 12.2.203, 12.2.204 and 12.2.205 of the JRC.
We have identified a workaround, but it is not exactly elegant: Before executing the report we modify all empty parameters ("") to " " . In the PL/SQL function, we trim all parameters before using them.
We call the function using a command object with a sql syntax like this example:
select * from table (qa_batch_release.get_qa_br('{?p_report_id}','{?p_reg_set_number}','{?p_cr_number}','{?p_change_id_decode}','{?p_country_id}','{?p_mfg_item_no}','{?p_4_no}','{?p_5_no}','{?p_7_no}'))
The PL/SQL function is a table returning function.
Best regards, ThorHi Kishore,
using #COLUMN_VALUE# would probably not make much sense, because normally a report has multiple columns and not just the numeric column which you want to verify if it's negative. But APEX will fire the template condition for each column, because the report template is a column cell template.
What you can do to make it more generic is to use for example
#CHECK_AMOUNT#
in the template and provide a not displayed column in your SQL statement which contains your value which is named CHECK_AMOUNT. For example:
SELECT NAME
, BALANCE
, BALANCE AS CHECK_AMOUNT
FROM XXX;Because this CHECK_AMOUNT column would be a generic name, you can use this template in all your reports as long as you provide this column.
Thope that helps

XMLType schema detail lost in pl/sql function for a jdeveloper webservice
If I write a very simple pl/sql procedure to wrap as a web service to return the XML from an XMLtype table column, the jdeveloper (11.1.1.3) web service generation process seems to ignore the detail
of the registered XMLTypes' schema, and converts the 'output' to an xsd:string in the generated WSDL file, which has knock on effect that generated data controls are 'dumb' in only seeing output as a string, and providing no real data functionality at XML schema level. Since I know web service data controls work fine when provided with the correct level of detail in the WSDL, what am I missing in terms of pursuading jdeveloper to generate wsdl's with full xsd schema info for the return XMLType?
This is my table:
ID NOT NULL NUMBER(12)
SPEC SYS.XMLTYPE(XMLSchema "http:
//localhost:8080/public/demo
/xsd/sample2.xsd" Element "b
ooks") STORAGE BINARY
PRD_ID NOT NULL NUMBER(10)

EDIT_NO NOT NULL NUMBER(6)
PUBLISHED_BY_PEO_ID NUMBER(10)
PUBLISHED_ON_DT DATE
EFFECTIVE_FROM_DT NOT NULL DATE
EFFECTIVE_TO_DT DATE
=======================================================
This is the XML Schema:

Question about PL/SQL Function in report
Hi all. I have a (basic) question about using a PL/SQL function in a report. In my report page I have an item (PL/SQL function) that has the following syntax:
return username from t1
where username like 'Le%'
I reference this item in an email process. Ideally this function would return all usernames that begin with 'Le' in the drafted email; however, its not looping so I'm only getting a return on the first name.
I have a few books on PL/SQL but I'm not exactly sure where to start - I imagine there is a loop process I need to integrate into the function but, like I said, I'm not sure.
I would have posted this to the PL/SQL forum but also wanted some feedback on whether or not using this method is the best way forward. Essentially I have a table with usernames and just want to send email messages based on some simple logic.
Thanks!
LenHi Sergio,
First, it's an honor to have you reply to my post. Thanks!
To be more specific,
T1 is a table containing the results from a user security scan. Username is a column in this table containing user names. What I have done is create a page in HTML DB with the following elements:
1. An 'Item' containing the PL/SQL function that is hidden. The purpose of this Item is to generate information from T1 that meets the simple logic parameters - in this case, the user names that begin with "Le". I have called this Item P145_TT
2. A 'Process' containing references to HTMLDB_MAIL. The 'Process' looks similar to this:
HTMLDB_MAIL.SEND(
P_TO => '[email protected]',
P_FROM => 'Anon Email Account',
P_BODY => 'Note: This message was automatically generated. Do not attempt to reply to this email.
These are the users that begin with Le: '||:P145_TT||' ',
P_SUBJ => 'Summary');
3. A 'Button' to submit the process and (hopefully) send the message containing all users that adhere to the logic in the function.
4. If I use 'return username from t1...' I will get a username generated, but like I said previously, it only gives me the first and does not loop. -
Need to obtain updateable ResultSet via call to PL/SQL function
I'm using JDBC and the Oracle JDBC driver to call a PL/SQL function that returns a SYS_REFCURSOR. I do this via a CallableStatement object and then cast the output parameter to a ResultSet object. However, I want this ResultSet object I end up with to be updateable. The following code throws an exception stating "Invalid operation for read only resultset: updateString ":
cstmt2 = con.prepareCall("{? = call get_upload_entry_for_update(?)}",
ResultSet.TYPE_FORWARD_ONLY,
ResultSet.CONCUR_UPDATABLE);
cstmt2.registerOutParameter(1, OracleTypes.CURSOR);
cstmt2.setInt(2, newUploadId);
cstmt2.execute();
rs = (ResultSet) cstmt2.getObject(1);
rs.next();
rs.updateString("UPLOAD_FILENAME", fileName);
// . . .So even though, I create the CallableStatement such that ResultSets should be updateable, it's not allowing me to do any updates. Also, in case you're wondering, inside the PL/SQL function, the query on which the cursor is based is a select statement which does specify "for update" at the end.
I can get it to work as follows using a Statement object that executes the SELECT statement directly instead of a CallableStatement that executes a PL/SQL function:
Statement stmt = con.createStatement(ResultSet.TYPE_FORWARD_ONLY, ResultSet.CONCUR_UPDATABLE);
rs = stmt.executeQuery("select UPLOAD_FILENAME, UPLOAD_FILE from rf_upload where upload_id = "+newUploadId+" for update");
rs.next();
rs.updateString("UPLOAD_FILENAME", fileName);
//. . . Although this works, the project I'm working has a goal to encapsulate all SQL into Functions and Stored Procedures so I'd like to get it working that way instead.
So the bottom-line question is: Using the Oracle JDBC driver, how can I call a PL/SQL function in such a way that I can obtain an updateable ResultSet object?
Thanks for any suggestions. I'd be happy to clarify anything that's unclear.Hmmm...
I'm still scratching my head about this one, just not sure it's doable, but I'll point out something, maybe it will give you a clue...
In your code, you have:
cstmt2 = con.prepareCall("{? = call get_upload_entry_for_update(?)}",
ResultSet.TYPE_FORWARD_ONLY,
ResultSet.CONCUR_UPDATABLE);I don't think the ResultSet parameters do anything towards your goal of getting an updatable result set via the returned cursor, those parameters affect the result set produced if you were to call:
ResultSet rs2 = cstmt2.executeQuery();and not the result set generated by:
rs = (ResultSet) cstmt2.getObject(1);Futhermore, while the "FOR UPDATE" is almost certainly something you want to do, it also doesn't affect the cursor (I think) but merely locks the affected rows in the DB.
You might try calling rs.getType() and rs.getConcurrency() on the ResultSet you get from getObject, though I suspect they'll merely confirm the bad news that the cursor your getting back isn't right...
You also might try the Oracle-specific getCursor call:
rs = ((OracleCallableStatement)cstmt2).getCursor (1)instead of getObject, though I don't think it will help...
I've been curious enough to dig around through most of my handy references and Oracle's docs and MetaLink and come up mostly empty, although almost 5 years ago Oracle Support said:
" Reference Cursors from a pl/sql stored procedure are not updateable in any language." -
SQL report region source to call a pl/sql function using DB link
Hi - I have a pl/sql function fn_dbtype(id NUMBER) defined in database X. The pl/sql function executes couple DML statements and returns a string (a SELECT query). I am able to call this function using SQL Plus (Connected to Database X) as below and it works fine:
declare
vSQL VARCHAR2(100);
begin
vSQL := fn_dbtype(1);
end;
The DML operations completed fine and vSQL contains the "Select" query now.
In APEX:
I am trying to create a SQL report in APEX using SQL query(PL/SQL function returning a sql statement) option. I am trying to figure out what to put in the region source so that the output of the "Select" query is displayed in the report.
Moreover APEX is hosted in a different database instance. So I would need to call this pl/sql function using a DB Link.
Please let me know what I need to put in the region source to execute the pl/sql function which returns the "Select" query thereby displaying the query output in the report. Thanks.

Pass a value from a PL/SQL function to a javascript (html header) ? ?
Hey Guys,
Have a question regarding how to pass a value from a PL/SQL function to a javascript in the HTML Header.
I have created a PL/SQL function in my database, which does looping.
The reason for this is: On my apex page when the user selects a code, it should display(or highlight buttons) the different project id's present for that particular code.
example= code 1
has project id's = 5, 6, 7
code 2
has project id's = 7,8
Thank you for your Help or Suggestions

The PL/SQL function :
CREATE OR REPLACE FUNCTION contact_details(ACT_CODE1 IN NUMBER) RETURN VARCHAR2 IS
Project_codes varchar2(10);
CURSOR contact_cur IS
SELECT ACT_CODE,PROJECT_ID
FROM ACTASQ.ASQ_CONTACT where ACT_CODE = ACT_CODE1;
currec contact_cur%rowtype;
NAME: contact_details

I have made the following modifications to your app to get it to work as I thing you need it to.
1) Changed the source for the HTML Buttons Region(note use of id vs name for the Buttons)
<script>
function hilitebtn(val) {
//gray buttons
$x('graduate').style.backgroundColor='gray'
$x('distance').style.backgroundColor='gray'
$x('career').style.backgroundColor='gray'
$x('photo').style.backgroundColor='gray'
//AJAX call to get project-ids
var get = new htmldb_Get(null,$x('pFlowId').value,'APPLICATION_PROCESS=GETPROJECTS',0);
get.addParam('x01',val)
gReturn = get.get();
var arr=gReturn.split(':'); //dump into array
get = null;
for (i=0;i<arr.length;i++) {
// alert('val=' + arr);
if ( arr[i]==5)
$x('graduate').style.backgroundColor='red';
if ( arr[i]==6)
$x('distance').style.backgroundColor='red';
if ( arr[i]==7)
$x('career').style.backgroundColor='red';
if ( arr[i]==8)
$x('photo').style.backgroundColor='red';
</script>
<table cellpadding='0' cellspacing='0' border='0'>
<tr><td>
<input type='button' id='graduate' value='Graduate'>
</td>
<td>
<input type='button' id='distance' value='Distance'>
</td>
<td>
<input type='button' id='career' value='Career/Tech'>
</td>
<td>
<input type='button' id='photo' value='Photos'>
</td>
</tr></table>
2) Defined the application process GETPROJECTS as DECLARE
IDS varchar2(1000);
l_act_code varchar2(100) :=4;
begin
IDS:='';
l_act_code := wwv_flow.g_x01;
for x in(
SELECT ACT_CODE,PROJECT_ID
FROM ASQ_CONTACT
where ACT_CODE = l_act_code)
LOOP
IDS := IDS || X.PROJECT_ID|| ':' ;
END LOOP;
HTP.PRN(IDS);
END;
3) Changed the 'onchange' event-handler on p1_act_code to be 'onchange=hilitebtn(this.value)'
4) Added the JS to the HTML Page Footer <script>
hilitebtn($v('P1_ACT_CODE'));
</SCRIPT>
