Missing PL/SQL function TO_BINARY_INTEGER
In "Oracle 8i: The Complete Reference" it mentions the function TO_BINARY_INTEGER. This is exactly the function I need. However, in trying to use it in stored function, I keep getting the error that it is not defined. Does this function in fact exist? If so, how should I be accessing it.
I have the recently published Oracle 8i DBA Certified Professional DBA Certificantion Exam Guide.
It lists TO_CHAR, TO_DATE, TO_MULTI_BYTE, TO_NUMBER, and TO_SINGLE_BYTE functions but does not list the one you describe.

Application Report Missing PL/SQL Functional Area
All,
I just wanted to bring to the ApEx developers something I just noticed... I use the Shared Components > Database Object Dependencies report to make sure all is well before moving applications into production.
The Parsing Errors feature of that report is WONDERFUL! But it seems to be overlooking buttons that use a conditional display based on PL/SQL Function Body Returning a Boolean.
DanHi Dan,
I think the place is perfect, but I read once somewhere that "Bug" or "Bug Report" should be in the subject so that's easier to find for the Oracle guys.

Query on Reoprts-pl/sql function body returning sql query
Hi,
I am facing a starnge problem.. and would like to know the reason for it.
The situation is as follows:
I have a report (pl/sql function body returning sql query based). My query is as follows:
declare
l_query1 varchar2(2000);
begin
if (:P102_min_value is not null and :P102_max_value is null) then
l_query1 := 'select decode(:P102_date,'1',date1) Transaction_Date, decode(:P102_first_name,'2',first_name) First_Name from (
select * from MORTGAGE_LOAN_LEADS where APPRX_LOAN_AMOUNT >=:P102_min_value
return (l_query1);
end if;
end;
This returns the error as :
1 error has occurred
Function returning SQL query: 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-06550: line 7, column 20: PLS-00103: Encountered the symbol "1" when expecting one of the following: * & = - + ; < / > at in is mod remainder not rem <> or != or ~= >= <= <> and or like LIKE2_ LIKE4_ LIKEC_ between || multiset member SUBMULTISET_)
How do i correct this? am i right in thinking that the single quotes indicating a string within a select query is creating the problem? Beacuse if i use an sql query report and use the following query, it is working fine...
select
decode(:P102_date,'1',date1) Transaction_Date,
decode(:P102_first_name,'2',first_name) First_Name
from (
select * from MORTGAGE_LOAN_LEADS where APPRX_LOAN_AMOUNT >=:P102_min_value
But i need to write pl/sql function, so that multiple report can be returned based on different conditions. Please guide me.
Thanks,
SumanaDoes that mean that both in if and else we need to have same columns selected?
if thats the case.. any idea how i can implement it in my code. The situation here is that the columns that need to be selected are dynamic and keep on changing...
if i try to implement like this and run the page, it gives the following error:
Query is:
declare
l_query1 varchar2(4000);
begin
if apex_application.get_current_flow_sgid(:APP_ID) = apex_application.get_sgid then

elsif (:P102_min_value is null and :P102_max_value is not null) then

else
l_query1 := 'select date1,first_name from MORTGAGE_LOAN_LEADS where rownum = 1';
end if;
else
l_query1 := 'select date1,first_name from MORTGAGE_LOAN_LEADS where rownum = 1';
end if;
return l_query1;
--dbms_output.put_line( l_query1);
end;
The Error is:

I'm able to get the mouse back by dragging the window out of maximize position.

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?

Sql query(PL/SQL function body return SQL query) with in(x,y,z) condition
Hello,
I've set up a region definition of type "SQL Query(PL/SQL function body return SQL query). In my query I make use of an "in" condition. When I populate :P755_INC_BARG_UNIT with a value of 0F (no quotes), I get the correct count. However, when I set :P755_INC_BARG_UNIT to 0F, 0E I get an invalid count. What do I have to set the page item to?
When running the query in TOAD, and setting :P755_INC_BARG_UNIT to the string inside the brackets (0F, 0E) I get the proper count.
The code I use is shown below. Any help would be appreciated,
Alex.
DECLARE
v_sql VARCHAR2(32767);
BEGIN
SELECT count(*) "cnts",
''Faculty data file IDs missing in appt table'' "err_type"
FROM hradmin.et_faculty_salary fs left outer join
hradmin.appointments appt
ON trim(fs.empl_id) = appt.emp_emp
and appt.ear_activ <> ''Z''
and appt.ear_type = ''F''
and (appt.ear_class in (''A'',''B'',''C'',''D''))
and appt.ear_bargunit in ( :P755_INC_BARG_UNIT )
WHERE appt.emp_emp is null
RETURN v_sql;
END;Alex,
try something like:
DECLARE
v_sql VARCHAR2(32767);
BEGIN
v_sql := <YOUR_SQL_STATEMENT_WITH_P755_INC_BARG_UNIT_IN_IT>;
v_sql := REPLACE(v_sql, ':P755_INC_BARG_UNIT',:P755_INC_BARG_UNIT);
RETURN v_sql;
END; But before doing it read this:
http://asktom.oracle.com/pls/apex/f?p=100:11:0::::P11_QUESTION_ID:210612357425
After reading you will be able to find the best solution yourself.

In my original email I should have made the point clear that an indexed
column was required, that led to some confusion, apologies.
Under Oracle 7 even if the column is indexed the query engine still does a
full scan of the index to find the maximum or minimum value. As strange as
this seems it is possible to view it using the Oracle trace functions such
as tkprof. This method is quicker than not having an index but the cursor
method is far more efficient.
When using a cursor based approach Oracle will go straight to the first
record of the index (depending on MAX or MIN) and retrieve the data. By
exiting at that point the function has been performed and the I/O operations
are extremely low compared to a full index scan.
Of course there is a trade off depending on the amount of rows but for large
indexed tables the cursor approach will be far faster than the normal
functions. I'm not sure how other RDBMS's handle MAX/MIN but this has been
my experience with Oracle. This process may be faster still by using PL/SQL
but then you are incorporating specific database languages which is
obviously a problem if you port to a different RDBMS. Here is some code you
can try for Oracle PL/SQL functions:
declare
cursor myCur1 is
select number_field
from number_table
order by number_field desc;
begin
open myCur1;
fetch myCur1 into :max_val;
close myCur1;
end;
I hope this clarifies things a bit more. If in doubt of the execution plan
of a performance critical query use the database trace functions as they
show up all sorts of surprises. MAX and MIN are easy to understand when
viewing code but perform poorly under Oracle, whether v8 behaves differently
I have yet to discover.
Cheers,
Dylan.

Subject: RE: SQL functions in TOOL code
I guess my point is that MAX can always be implemented more
efficiently than the SORT/ORDER-BY approach (but may not be the
case, depending on the RDBMS). If an ORDER-BY
can use an index (which means that the indexing mechanism involves
a sorted collection rather than an unordered hashtable) so can
MAX - in which case finding a MAX value could be implemented
in either O(1) or O(logn) time, depending on the implementation.
The last sentence being the major point of this whole discussion,
which is that your mileage may vary depending on the RDBMS - so
try using both approaches if performance is a problem.
In terms of maintenance, MAX is the much more intuitive approach
(In My Opinion, of course), since a programmer can tell right away
what the code is attempting to do.

Well, yes, but in that specific case (looking for max() value) would not
be
true that, if you have an index (and only then) on that specific column
some
databases (like Oracle) will be smart enough to use index and find max
value
without full table scan and without using order by clause?

If (and only if) an index exists on the exact columns in the ORDER BY
clause, some databases are smart enough to traverse the index (inforward
or
reverse order) instead of doing a table scan followed by a sort.
If there is no appropriate index, you always end up with some kind ofsort
step.
Of course this is all highly schema- and database-dependent, so youmust
weigh those factors when deciding to exploit this behavior.

This seems a bit counter-intuitive to me... primarily due to
the fact that both MAX and ORDER-BY functionality would require
a full table scan on the given column... no? However, I would
think that a MAX can be implemented more efficiently since it
just requires the max value in a given set (which can be performed
in O(n) time on an unordered set) versus an ORDER-BY (sort)
performance on an unordered set of at best O(nlogn) time.
Am I missing something? Please set me straight on this 'un.

Subject: RE: SQL functions in TOOL code
Hi Van,
Operating a function such as MAX or MIN is possible as given in your
example
but it is worth pointing out the performance overhead with such a
method.
When you use MAX, Oracle will do a full table scan of the column so
if
you
have a great many rows it is very inefficient.
In this case use a cursor based approach and depending on your
requirments
(MAX/MIN) use a descending or ascending ORDER BY clause.
eg.
begin transaction
for ( aDate : SomeDateDomain ) in
sql select DATE_FIELD
from DATE_TABLE
order by
DATE_FIELD DESC
on session MySessionSO
do
found = TRUE;
aLatestDate.SetValue(aDate);
// Only bother about the first record
exit;
end for;
end transaction;
On very large tables the performance increases with the above method
will be
considerable so it is worth considering which method to use whensizing
your
database and writing your code.
Cheers,
Dylan.

Hi,
I know how to register PL/SQL functions in discoverer Admin and also how to export a folder or entire EUL from discoverer Admin and then also how to import them back.
But can someone please tell me how can i export existing pl/sql functions which are registered in Disc Admin to another instance of Disc Admin?
Thanks in advance.

Hi,
I want to use the EXTRACT function in Discoverer. I went through the Help for the «Import PL/SQL function» without success....
When I click the «Import» button, I see a HUGE list of functions, and I don't recognize which is the one I want.
I use that EXTRACT in the same database with PL/SQL developer and it works fine, but I get a «Function EXTRACT has not been registered with the EUL» message when I try to use it in Discoverer.
Any one knows how to «bring» the right function in the EUL ??
Thanks.I was able to import a Oracle standard package function SYS_CONTEXT and view it in Discoverer Desktop/Plus.
However when I create my own package function in a schema "xxdev" and then import via Disco Admin, I cannot view this function in Discoverer Desktop/Plus. These are the steps that I followed to implement it:
1. create package in xxdev schema
2. grant execute on package to noetix_sys & noetix_eul
3. register the function in Disco Admin
4. login to Disco Desktop/Plus and try creating a calculation field and lookup functions.
The function is not visible. I followed the exact same steps for STANDARD.SYS_CONTEXT function and it was visible. Is something missing in my steps to do?
Thanks in advance. -
Hi,
I couldn't manage to call a pl/sql function that takes some arguments or no arguments.
I couldn't find an example but searching through previous topics / discussions I could write something like this :
ExpressionBuilder expBuilder = new ExpressionBuilder();
Vector args = new Vector();
Vector parameters = new Vector();
// dynamically fill these vectors if there are any arguments to the function
Expression exp = expBuilder.getFunctionWithArguments(functionName, args);
DataReadQuery query = new DataReadQuery();
query.setSelectionCriteria(exp);
Iterator iter = args.iterator();
while (iter.hasNext())
query.addArgument((String)iter.next());
Object obj = getActiveUnitOfWork().executeQuery(query, parameters);
at the end what I get is NullPointerException, probably I'm missing something.

ADF 11g : Calling PL Sql Function
Hi there..
I am trying to call a PL/SQL Function from my application module in ADF 11g.
The code looks something like this
public void getName(int relationNumber) {
DBTransaction tc = getDBTransaction();
StringBuffer statement = new StringBuffer("begin ");
statement.append("? := COMP_RLE.RLE_GET_NAME(?);");
statement.append("end;");
OracleCallableStatement cs = (OracleCallableStatement)tc.createCallableStatement(statement.toString(), 0);
try {
cs.registerOutParameter(1, Types.VARCHAR);
cs.setInt(2, relationNumber);
cs.execute();
String retValue = cs.getString(1);
System.out.println(retValue);
} catch (SQLException e) {
System.err.println("Something went wrong: " + e.getMessage());
}When I run this in TOAD I get a result back in the form of a String.
However when I run the code above in a Unit Test I get back "null".
Does anybody know what I am doing wrong here?
Hope someone can help me out here.
Thanks in advance,
GideonI think it will probably work that way.. but the thing is.. I have been going over examples.. and they work with the CallableStatement.
I just want to know how come this isn't working the way it should.

SVG multiline chart based on PL/SQL function
Dear all -
Having trawled this forum and with a fair bit of experimentation I've concluded that:
1. Generating an SVG line series using a PL/SQL function returning a SQL statement is perfectly possible;
BUT
2. It only works for a single series. Adding further series blanks out the SVG chart area and nothing at all is displayed.
Can anyone tell me if this is right or am I missing a trick? The usual problems such as ordering, nulls etc. don't apply in this case.
Thanks for your time.
John.On some, but not all SVG line charts, I had trouble when some values are ZERO.
Putting a CASE WHEN var = 0 then 0.05 ELSE var END in the select statement
fixed those situations.
I had missing lines when the number of data points in a series exceeded the default number of 15, and I did not set in the series configuration to a number equal to or higher that the number of data points in that series.
And I had one instance, where a couple missing lines reappeared when I exited
the browser and app completely and restarted the app.
All these comments apply to ver 1.6x and 2.0x -
Report- Pl/sql function returning sql query parsing page items as text?
Hi Team,
I am facing a strange issue .
I have four page items namely
1)JOB_CODE
2)MIN_EXP
3) MAX_EXP
4) SOURCES1
I have a report of the type "Pl/sql function returning sql query"
declare
v_sql varchar2(4000);
begin
if (:JOB_CODE IS NOT NULL and :MIN_EXP IS NOT NULL and :MAX_EXP IS NOT NULL and :SOURCES1 IS NOT NULL) then
v_sql:= 'select v_candidate_id, v_fname,v_current_employer,v_Experience_years from candidature where V_REQUIREMENT = :JOB_CODE and v_experience_years >= :MIN_EXP and v_experience_years <= :MAX_EXP and source like ' || '''' || '%'|| ':SOURCES1' || '%' || '''';
elsif (:JOB_CODE IS NULL and :MIN_EXP IS NOT NULL and :MAX_EXP IS NOT NULL and :SOURCES1 IS NOT NULL) then
v_sql := 'select v_candidate_id, v_fname,v_current_employer,v_Experience_years from candidature where v_experience_years >= :MIN_EXP and v_experience_years <= :MAX_EXP and source like ' || '''' || '%'|| ':SOURCES1' || '%' || '''';
elsif (:MIN_EXP IS NULL and :JOB_CODE IS NOT NULL and :MAX_EXP IS NOT NULL and :SOURCES1 IS NOT NULL) then
v_sql := 'select v_candidate_id, v_fname,v_current_employer,v_Experience_years from candidature where v_experience_years <= :MAX_EXP and V_REQUIREMENT = :JOB_CODE and source like ' || '''' || '%'|| ':SOURCES1' || '%' || '''';
elsif (:MAX_EXP is null and :JOB_CODE IS NOT NULL and :MIN_EXP IS NOT NULL and :SOURCES1 IS NOT NULL) then
v_sql := 'select v_candidate_id, v_fname,v_current_employer,v_Experience_years from candidature where V_REQUIREMENT = :JOB_CODE and v_experience_years >= :MIN_EXP and source like ' || '''' || '%'|| ':SOURCES1' || '%' || '''';
end if;
insert into query_list values (v_sql);
insert into debug values (:JOB_CODE , :MIN_EXP , :MAX_EXP , :SOURCES1);
return v_sql;
end;
Please not that I am insertin the query into a table called Query_list and the page item values into the table called Debug thru the pl/sql function which returns teh query.
Now I select the data from the debug tables.
select unique(query) from query_list;
select v_candidate_id, v_fname,v_current_employer,v_Experience_years from candidature where V_REQUIREMENT = :JOB_CODE and v_experience_years >= :MIN_EXP and v_experience_years <= :MAX_EXP and source like '%:SOURCES1%'
select * from debug;
JOBCODE MINEX MAXEX SOURCE
21 1 10 donkeyHire
And if I run the query in sql I get some records returned
select v_candidate_id, v_fname,v_current_employer,v_Experience_years from candidature where V_REQUIREMENT = 21 and v_experience_years >= 1 and v_experience_years <= and source like 'donkeyHire'
V_CANDIDATE_ID V_FNAME V_CURRENT_EMPLOYER V_EXPERIENCE_YEARS
2 Vengu Andale Tech 4
But the record does not show up in the report!
does this type of report parse page items as text?
Why is it so?
Waiting for an early reply.
Thanks,
venkatVenkat - You don't want to put ':SOURCES1' in quotes like that.

Passing Multiple Values from a worksheet to PL/SQL function.
Hi All,
Is there any way to pass multiple values selected in a worksheet to a PL/SQL function ?
I will try to explain the scenario:
We have a crosstab report that showing all the customer details, deposit sum of a customer in each date in a date range selected. With the customer details we are showing the Rank of a customer based on the deposit in the latest date selected. Filtering is based on the rank, ie Top50 or Top60 etc.( As I said rank is calculating based on the deposit in the latest date).This is working fine.
Now the new requirement is to : For example, in Top50 report, list all the customers, who were in the Top50 list, in any of the dates selected. We are able to display the daywise rank, but when giving a condition like daywiserank <= 50, the result becomes uncertain. Some blank lines, wrong amounts etc..
As a work around we tried to find out the rank in a PL/SQL function. But the issue there is : we have some multiple value parameters used in the worksheet.
Is there any way to pass multiple values selected in a worksheet to a PL/SQL function ?
Or any other work arounds for the scenario explained?
Reagrds,
JeneeshHi Russ,
Thanks for the response.

1. I thought there was an analytical function similar to rank - or maybe an option of rank - that if there are duplicate records to have them all considered the same rank. So if you had 3 records all the same as rank=2 then a condition saying where rank=2 would return the 3 records. You could check into this.
We are already using DENSE_RANK. But the issue is the output contains incorrect null values nd repeated rows.
We got it solved as I explained in the previous post. But will that AGGREGATION MODE setting ( Which discoverer says - not recommended) have any issue? I mean side effects?
Russ Proudman wrote:
2. Another thought is that you can create a PL/SQL routine - that's called from a SQL function registered in Discoverer - where a table is created that does the first part of your query. Then a worksheet is created to use the data from that table. So, in essence, the table would have your top50 ranked customers. Then you can write any kind of worksheet against that table. However, DBAs are loath to allow tables - that they didn't create! - many times in a PROD environment.
Here also the same problem will occur: as the top 50 will depend upon the parameters. I cannot pass those parameters to PL/SQL Function.And storing the top50 ( itmay be top100 or to 150 also) for all combinations of the parameters is impossible
Russ Proudman wrote:
3. Finally, are you sure you're rank function is correct in that if you're getting blank lines, maybe the 'over' part is not considering all columns needed to determine the rank?
Yes the query we are using is correct. The output QUERY of discoverer gives correct results in Sqlplus.
