Any function in SQL or PL/SQL

how the occurance-position of a particular character in a given string can be extracted with in a pl/sql block or procedure. is there any function available to do so.

Maybe the INSTR function.

SQL Query (PL/SQL Function Body returning SQL query) doesn't return any row

I have a region with the following type:
SQL Query (PL/SQL Function Body returning SQL query).
In a search screen the users can enter different numbers, separated by an ENTER.
I want to check these numbers by replacing the ENTER, which is CHR(13) || CHR(10) I believe, with commas. And then I can use it like this: POD IN (<<text>>).
It's something like this:
If (:P30_POD Is Not Null) Then
v_where := v_where || v_condition || 'POD IN (''''''''||REPLACE(''' || :P30_POD || ''', CHR(13) || CHR(10), '','')||'''''''''')';
v_condition := ' AND ';
End If;
But the query doesn't return any rows.
I tried to reproduce it in Toad:
select * from asx_worklistitem
where
POD IN (''''||REPLACE('541449200000171813'||CHR(13) || CHR(10)||'541449206006341366', CHR(13) || CHR(10), ''',''')||'''')
==> This is the query that does't return any rows
select (''''||REPLACE('541449200000171813'||CHR(13) || CHR(10)||'541449206006341366', CHR(13) || CHR(10), ''',''')||'''')
from dual;
==> This returns '541449200000171813','541449206006341366'
select * from asx_worklistitem
where pod in ('541449200000171813','541449206006341366');
==> and when I copy/paste this in the above query, it does return my rows.
So why does my first query doesn't work?
Doe anyone have any idea?
Kind regards,
Geert

Thanks for the help.
I made it work, but via the following code:
If (:P30_POD Is Not Null) Then
v_pods := REPLACE(:P30_POD, CHR(13) || CHR(10));
v_where := v_where || v_condition || 'POD IN (';
v_counter := 1;
WHILE (v_counter < LENGTH(v_pods)) LOOP
v_pod := SUBSTR(v_pods, v_counter, 18);
IF (v_counter <> 1) THEN
v_where := v_where || ',';
END IF;
v_where := v_where || '''' || v_pod || '''';
v_counter := v_counter + 18;
END LOOP;
v_where := v_where || ')';
v_condition := ' AND ';
End If;But now I want to make an update of all the records that correspond to this search criteria. I can give in a status via a dropdownlist and that I want to update all the records that correspond to one of these POD's with that status.
For a region you can build an SQL query via PL/SQL, but for a process you only have a PL/SQL block. Is the only way to update all these records by making a loop and make an update for every POD that is specified.
Because I think this will have a lot of overhead.
I would like to make something like a multi row update in an updateable report, but I want to specify the status from somewhere else. Is this possible?

SQL Query (pl/sql function body returning Sql query)

Hi All,
I have created a region of "SQL Query (pl/sql function body returning Sql query)" type and it is working fine , but when I am migrating(export /import) this application from development to systest environment ,
It gives error for this region :
Error ERR-1101 Unable to process function body returning query.
OK
ORA-06550: line 1, column 52: PLS-00306: wrong number or types of arguments in call to 'FU_TRADE_REPORT_QUERY' ORA-06550: line 1, column 45: PL/SQL: Statement ignored
Any pointer ...why this is happening.
Thanks

If your function is a stored function that is called from within APEX (function body not coded into the app itself), have you made sure that the function has been created and compiles ok prior to installing your apex app.
If there are some dependency issues between other PL/SQL units or database objects that are causing your function not to be compiled, you apex install will fail as you are trying to reference an uncompelled bit of pl/sql.
Let me know how you get on

Hello Friends,
I have a page with type SQL Query ( PL/SQL function body returning query ).

It looks like the query string you are trying to pass back exceeds the 32K limit for a varchar. Where this is happening is kind of difficult to tell as it could be any number of points, and also depends on what you are passing into the process via page items.
I would first try to establish what combination of page items causes this error to occur. Then, starting from the bottom and working your way backwards, I would start 'switching off' some of the items you use to build your query until it breaks again, thus establishing which part is leading to the error.
Also, I'm not sure what :P10_STMT is doing (are you maybe using this for visiblity of the query created)?

SQL Query (PL/SQL function body returning SQL query) when using to_char

we are trying to build a report page of Type SQL Query (PL/SQL function body returning SQL query).
our query is so simple, we need to extract the month from the recording_date column.
declare
l_query varchar2(1000);
begin
l_query:='select to_char(recording_date,'MM')from re_productive';
return l_query;
end;
but we are having the following problem for this query
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 4, column 42: PLS-00103: Encountered the symbol "MON" when expecting one of the following: . ( * @ % & = - + ; < / > at in is mod remainder not rem <> or != or ~= >= <= <> and or like between || multiset member SUBMULTISET_ The symbol ". was inserted before "MON" to continue.)
Notes:
1-the query is correct and it was tested under Toad and SQL Plus.
2- we tried Use Generic Column Names (parse query at runtime only) option but we get the same problem.
any quick help please.

Hi
You haven't escaped your quotes in the string. Try this...
DECLARE
l_query VARCHAR2(32767);
BEGIN
l_query:= 'select to_char(recording_date,''MM'') from re_productive';
RETURN l_query;

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);

Wild card searching in sql squery (pl/sql function body returning......)

Hi,
I've a report based on a sql query (pl/sql function body returnin a sql query).
One of the statements is
select .. from ...
where name_of_person = :P17_NAAM
I like to built a wild card possibility (with like '%l%m%') to show all persons with in their name an l, and an m (after the l)
how to modify this statement?
any reaction will be appreciated.
Leo

Leo,
If I understand you correctly, you want to let the user type the value without wild cards, and than to add them programmatically. If that's the case, here is what you can do:
1. Create a new item, say P17_HIDDEN_NAAM, that will contain the actual search criteria
2. Modify your pl/sql to:
begin
:p17_hidden_naam := null;
for l_i in 1..length(:P17_NAAM)
loop
    :p17_hidden_naam := :p17_hidden_naam || '%' || substr(:P17_NAAM, l_i, 1);
end loop;
:p17_hidden_naam := :p17_hidden_naam || '%';
return
    'select ..
       from ...
      where name_of_person like :p17_hidden_naam';
end;By the way, I think that it's much better to train your users to use wild cards than to do it in the program.

Log Function behaving diffently in SQL vs Pl/SQL

Hello
This equation works OK in SQL but its implementation in PL/SQL throws an error:

Any assistance would be appreciated

SQL> Oracle still maintains two separate engines for SQL and PL/SQL. And the above bug is obviously related to that. Now same built-in function has separate implementation SQL and PL/SQL. In PL/SQL it is package STANDARD. At first I thought it is where bug manifests itself. However:
SQL> SELECT CAST(sys.standard.LOG(2,32) as FLOAT) FROM DUAL;
CAST(SYS.STANDARD.LOG(2,32)ASFLOAT)

Percentile & percentage function in SQL or PL/SQL ?

Hi all,
I was wondering if there is any
Percentile or percentage functions in SQL or PL/SQL to calculate ??
I came across percentile_rank , but i didnt find really good example online .... so i wasnt sure if thats right function for calculating percentile Any example will be great !!
THank you so much !!!

Thank you so much frank and tubby !! It just amazing to see so many powerful aggregate and anlytic functions are available in 11g.
Here is the example data i was working on
with x as (
select '100' value_amt, '6' cnt from dual union all
select '200' value_amt, '5' cnt from dual union all
select '500' value_amt, '10' cnt from dual union all
select '700' value_amt, '12' cnt from dual union all
select '900' value_amt, '14' cnt from dual )
select * from x;
I m trying to calucalte the column called "avg_value" by dividing " value_amt / cnt ". I was just wondering if i need to use any function to calculate
Here is the column "avg_value" look like
with y as (
select '100' value_amt, '6' cnt, '16' avg_value from dual union all
select '200' value_amt, '5' cnt, '40' avg_value from dual union all
select '500' value_amt, '10' cnt, '50' avg_value from dual union all

Is SQL Connection Function or API Availble in SQL Toolkit 2.2 (Urgent) ?

Hello,
I have build an application using LabWindows 2010 and SQL Toolkit 2.2. Is there any function or dll or api availble so that i do not want to make connection in control panel ODBC ?.
Regards
Umer
Solved!
Go to Solution.

Hello,
The manual for this toolkit might be a good reference for you: LabWindows/CVI SQL Toolkit Help
There is a function called DBConnect, which allows you to connect to a database programmatically. The Help says:
"Purpose: Opens a to a database system to allow execution of SQL statements. Calling DBConnect is equivalent to calling DBNewConnection and then DBOpenConnection"
There's also a page in the help titled Connecting to a Database, which tells you more information about how to use DBConnect:
"Use DBConnect to connect to a data source. The only parameter is a connection string, which must contain the data source or provider name and any other attributes the database requires. DBConnect returns a handle to the database connection that other functions in the toolkit use. Call DBDisconnect to close the database connection, passing in the database connection handle from DBConnect. The following code is a simplified version of the code found in connect.prj.
int hdbc = 0; /* Handle to database connection. */
int rescode; /*Result code. */
/* Connect to CVI_Samples data source. */
hdbc = DBConnect ("DSN=CVI Samples");
if (hdbc <= 0) goto Error;
/* Disconnect from database. */
resCode = DBDisconnect (hdbc);
if (resCode != DB_SUCCESS) goto Error;"
Hope this helps.

SQL query (pl/sql function body returning query) performance issue

I create my report in building my sql instruction with ( SQL Query pl/sql function body returning sql query );
My report take more than 20 seconds however if i did a cut and paste with the sql code in TOAD the same sql take 1 second.
To try to discover the source of the problem; i take the sql generated by the function and i create another report ( sql query ) this new report take 2 seconds.
My query is very big 25,000 characters with database link.
What is the difference between SQL-quey and sql-query(pl/sql function body returning sql query)
Thanks
Marc

Marc,
Firstly...don't compare the timings from Toad, since often Toad only fetches the first few records for you (i.e. it pages them).
Secondly....the database link could be a factor here, but without seeing your query it's too hard to say.
Can you post the query somewhere (on a webserver say)?
