Vector Average function in T-SQL

Hi - We need to calculate the Vector Average of the Wind direction based on Wind speed in SQL Server. Normal Average function is not suitable for us. Has anyone earlier worked similar requirement. Please let me know how you have solved it.
thanks

It's looking like you need to determine the "side" of the circle you need to be on by looking at the difference between your min and your max. If it's over 180 degrees, we need to go the other way. Using that, we can have a case statement make
the changes needed:
DECLARE @windDir TABLE (degrees FLOAT, recordedDateTime DATETIME)
INSERT INTO @windDir (degrees, recordedDateTime) VALUES
(350, '2015-04-07 08:00:00'),(350, '2015-04-07 08:05:00'),(350, '2015-04-07 08:10:00'),(350, '2015-04-07 08:15:00'),
(5 , '2015-04-07 08:20:00'),(5 , '2015-04-07 08:25:00'),(350, '2015-04-07 08:30:00'),(5 , '2015-04-07 08:35:00'),

PL/SQL function body returning SQL - report error:ORA-01403: no data found

Hi,
I am working on Application Express 4.0.2.00.06, and 11G database.
I have a problem with classic report area of type - PL/SQL function body returning SQL query. Query works if I define region area as - Use Generic Column Names (parse query at runtime only), and does not when I define it - Use Query-Specific Column Names and Validate Query.
I am getting error:
report error:ORA-01403: no data found
This is my query that is returned from function, and displayed with htp.p, and it works ok and returns data in SQL Developer and SQL Workshop (in Apex).
<code>
/* select 1 from dual */ SELECT SIFPRO, NAZIV, VODITELJ, DATPZA,SUM(DECODE(TJEDAN,'2010/46',BRDJEL,null)) as "2010/46" ,SUM(DECODE(TJEDAN,'2010/49',BRDJEL,null)) as "2010/49" ,SUM(DECODE(TJEDAN,'2010/50',BRDJEL,null)) as "2010/50" ,SUM(DECODE(TJEDAN,'2010/51',BRDJEL,null)) as "2010/51" ,SUM(DECODE(TJEDAN,'2010/52',BRDJEL,null)) as "2010/52" ,SUM(DECODE(TJEDAN,'2011/01',BRDJEL,null)) as "2011/01" ,SUM(DECODE(TJEDAN,'2011/02',BRDJEL,null)) as "2011/02" ,SUM(DECODE(TJEDAN,'2011/03',BRDJEL,null)) as "2011/03" ,SUM(DECODE(TJEDAN,'2011/04',BRDJEL,null)) as "2011/04" ,SUM(DECODE(TJEDAN,'2011/05',BRDJEL,null)) as "2011/05" ,SUM(DECODE(TJEDAN,'2011/06',BRDJEL,null)) as "2011/06" ,SUM(DECODE(TJEDAN,'2011/07',BRDJEL,null)) as "2011/07" ,SUM(DECODE(TJEDAN,'2011/08',BRDJEL,null)) as "2011/08" ,SUM(DECODE(TJEDAN,'2011/09',BRDJEL,null)) as "2011/09" ,SUM(DECODE(TJEDAN,'2011/10',BRDJEL,null)) as "2011/10" FROM (SELECT * FROM PMV_PLAN_TVRTKA) GROUP BY SIFPRO, NAZIV, VODITELJ, DATPZA ORDER BY SIFPRO, NAZIV, VODITELJ, DATPZA

As you can see, I even tried with workaround that I found on the previous post on the forum, and that is to put /* select 1 from dual */ to start query.
Any help would be appriciated.

PL/SQL function body returning SQL query - ORA-06502: PL/SQL: numeric or value error

I'm attempting to dynamically generate a rather large SQL query via the "PL/SQL function body returning SQL query" report region option. The SQL query generated will possibly be over 32K. When I execute my page, I sometimes receive the "ORA-06502: PL/SQL: numeric or value error" which points to a larger than 32K query that was generated. I've seen other posts in the forum related to this dynamic SQL size limitation issue, but they are older (pre-2010) and point to the 32K limit of the DNS (EXECUTE IMMEDIATE) and DBMS_SQL. I found this post (dynamic sql enhancements in 11g) which discusses 11g no longer having the 32K size limitation for generating dynamic SQL. Our environment is on 11gR2 and using ApEx 4.2.1. I do not know which dynamic SQL method -- DNS or DBMS_SQL -- ApEx 4.2.1 is using. Can someone clarify for me which dynamic SQL method ApEx uses to implement the "PL/SQL function body returning SQL query" option?
As a test, I created a page on apex.oracle.com with a report region with the following source:
declare
l_stub varchar2(25) := 'select * from sys.dual ';
l_sql clob := l_stub || 'union all ';
br     number(3) := 33;
begin
while length ( l_sql ) < 34000 loop
    l_sql := l_sql || l_stub || 'union all ';
end loop;
l_sql := l_sql || l_stub;
for i in 1 .. ceil ( length ( l_sql ) / br ) loop
    dbms_output.put_line ( dbms_lob.substr ( l_sql, br, ( ( i - 1 ) * br ) + 1 ) );
end loop;
return l_sql;
end;
The dbms_output section is there to be able to run this code in SQL*Plus and confirm the size of the SQL is indeed larger than 32K. When running this in SQL*Plus, the procedure is successful and produces a proper SQL statement which can be executed. When I put this into the report region on apex.oracle.com, I get the ORA-06502 error.
I can certainly implement a work-around for my issue by creating a 'Before Header' process on the page which populates an ApEx collection with the data I am returning and then the report can simply select from the collection, but according to documentation, the above 32K limitation should be resolved in 11g. Thoughts?
Shane.

What setting do you use in your report properties - especially in Type and in Region Source?
If you have Type="SQL Query", then you should have a SELECT statement in the Region Source. Something like: SELECT .... FROM ... WHERE
According to the ERR-1101 error message, you have probably set Type to "SQL Query (PL/SQL function body returning SQL query)". In this situation APEX expects you to write a body of a PL/SQL function, that will generate the text of a SQL query that APEX should run. So it can be something like:
declare
mycond varchar2(4000);
begin
if :P1_REPORT_SEARCH is not null THEN
mycond:='WHERE LAST_NAME like :P1_REPORT_SEARCH ||''%''';
end if;
return 'select EMPLOYEE_ID, FIRST_NAME, LAST_NAME from EMPLOYEES ' ||mycond;
end;
And for escaping - are you interested in escaping the LIKE wildcards, or the quotes?
For escaping the wildcards in LIKE function so that when the user enters % you will find a record with % and not all functions, look into the SQL Reference:
http://download-uk.oracle.com/docs/cd/B19306_01/server.102/b14200/conditions007.htm
(You would than need to change the code of your function accordingly).
If you are interested in escaping the quotes, try to avoid concatenating the values entered by the user into the SQL. If you can, use bind variables instead - as I have in my example above. If you start concatenating the values into the text of SQL, you are open to SQLInjection - user can enter anything, even things that will break your SQL. If you really need to allow users to choose the operator, I would probably give them a separate combo for operators and a textfield for values, than you could check if the operator is one of the allowed ones and create the condition accordingly - and than still use bind variable for inserting the filtering value into the query.

Error in report when executing pl/sql function body returning sql query.

Hi,
I have used the pl/sql function body returning sql query for creating a report. I have created a datepicker(
P10_TASK_DATE) which can be submitted.The code is as below
DECLARE
v_sql varchar2(3000);
BEGIN
if :P10_TASK_DATE is not null THEN
v_sql:='select
* from tasks';
return v_sql;
else
v_sql:='select * from discovery';
return v_sql;
END IF;
END;if the date field is empty "select * from discovery" is executed and report is getting generated. But when we give a
date using date picker the page is submitted and i get "report error: ORA-01403: no data found" even
though the "tasks" table has data in it. Plz help
Thanks,
TJ

hi
Please try this
1. Create 2 region
1st region source=
select * from tasks'
go to the tab -> condition =
item NOT NULL
EXpression1 =:P10_TASK_DATE
this will run whenever the item have any date
2. open your 2 nd region source code= select * from discovery
put the condition
item is NULL
EXpression1 =:P10_TASK_DATE
thanks

Region source (PL/SQL function body returning SQL query)

Hi, guys.
Here is what i try to do:
Create a region of type SQL Query (PL/SQL function body returning SQL query). In the source area i tried to put this:
DECLARE
v_new VARCHAR2(10);
v_SQL varchar2(32000);
BEGIN
v_new := :P102_HDN_NEW;
-- htp.p(v_new);
IF v_new = 'N-Set' THEN
v_SQL := 'select ' ||
ELSIF v_new = 'Y-Set' THEN
v_SQL := 'select ' ||
END IF;
RETURN v_SQL;
END;
And here is the reply from APEX:
1 error has occurred
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. The query can not be parsed, the cursor is not yet open or a function returning a SQL query returned without a value.
Now.
1. Variable is set with the right value.
2. Each statement (separately) returns SQL that works with no problems
3. Problem occures if i try to put IF statement around the SQL creation.
4. If i select "Use Generic Column Names (parse query at runtime only)" instead of "Use Query-Specific Column Names and Validate Query" then the script returns SQL properly, however report's column names are set to Col1, Col2,Col3 ......

Timing of Report (function body returning sql) w/ pagination

Hey -
Wondered if someone can provide some insight here...
I have a report that is dynamically created by calling a function that returns sql. Since it may return a few hundred results I have pagination turned on allowing the user to choose rows per page, and am showing X-Y with next/prev links.
Before displaying the report the user has to choose some criteria to narrow down the result set - I'm finding something that I think is a bit strange in that it takes more time for the page to render when zero results are found vs. 100's of results. If I run the function and take the sql it creates, I can return 0 rows in .2 seconds and 508 rows in .5 seconds so I think the sql itself is fine. Other than debugging timings, how can I find out what is taking so long?
Debug for 0 results:
0.07: Region: Program Forecast (viewing SAVED values)
5.14: show report
5.15: determine column headings
5.15: parse query as: ####
5.15: print column headings
5.15: rows loop: 15 row(s)
10.32: Computation point: AFTER_BOX_BODY
Debug for 508 results (in chunks of 15):
0.07: Region: Program Forecast (viewing SAVED values)
2.76: show report
2.76: determine column headings
2.77: parse query as: ####
2.94: print column headings
2.94: rows loop: 15 row(s)
6.52: Computation point: AFTER_BOX_BODY
So it took only 6.5 seconds to pull 508 rows, look at my pagination and pull the first x rows, but 10.32 seconds to pull 0 rows and show me the no data found message. Even stranger is that in the 0 rows result it looped and took 5 seconds before it hit the next point (5 seconds doing what??)
Any ideas? I'm a little baffled here...I guess the next step is to trace it but I wanted to see if anyone had any ideas in the interim.

Where is the embarrassed icon?
After painstakingly copying over each item to a new page to test, I figured out performance starting sucking big time once I put a button out there that apparently had a less than optimal exists clause in it.
D'oh!

Unable to edit some functions in APEX Sql Workshop

Hi
Users are able to edit some procedures/functions in APEX SQL Work shop. ( Object Browser - functions - EDIT)
When we press edit we get cursor in the code area and can edit some procedures, But for some procedures when we click edit we don't get cursor in the code area and we are not able to edit the functions/procedures.
I am using fairfox browser.This is happening with only some. Is there any security.grants issue???
Thanks
Sree

Hi
This is happening with some procedures, For others this works fine.In IE I get red block in code area.
EDIT is working for some procedures so I think may not be the browser issue.
Thanks

Use of ROW_NUMBER() function in PL/SQL

I have a Table Emp with the following Structure
SQL> desc emp
Name Null? Type
EMPNO NUMBER(2)
ENAME VARCHAR2(50)
HIREDATE DATE
DEPTNO NUMBER(2)
If I write a following query on this table
SQL> SELECT deptno, hiredate, record_id
2 FROM (SELECT deptno, ename, hiredate, ROW_NUMBER()
3 OVER (ORDER BY hiredate) AS record_id
4 FROM emp)
5 WHERE record_id >= 2
6 AND record_id <=5;
The Result I get is
DEPTNO HIREDATE RECORD_ID
10 22-NOV-01 2
10 22-NOV-01 3
10 22-NOV-01 4
10 22-NOV-01 5
But if I put this query in a cursor in a PL/SQL block. The
pl/sql does not compiles and gives me the following address
SQL> DECLARE
2 CURSOR c_my IS
3 SELECT deptno, hiredate, record_id
4 FROM (SELECT deptno, ename, hiredate, ROW_NUMBER()
5 OVER (ORDER BY hiredate) AS record_id
6 FROM emp)
7 WHERE record_id >= 2
8 AND record_id <=5;
9 BEGIN
10 FOR c_rec IN c_my LOOP
11 dbms_output.put_line(c_rec.ename);
12 END LOOP;
13 END;
14 /

Question: Can you please tell me how I can use the ROW_NUMBER()
function in PL/SQL. I need to use this for selecting the correct
range of records for Pagination on a website.
Thanks in advance

As Andrew said, PL/SQL hasn't caught up with the newer bits of
SQL. I have heard that in 9i, they will be the same, but in 8i
there are still things that you can do in SQL that you cannot do
directly in PL/SQL, such as the new functions like ROW_NUMBER.
However, you can use NDS as a work around. The following does
the same as what you posted:
SET SERVEROUTPUT ON
DECLARE
TYPE c_my_type IS REF CURSOR;
c_my               c_my_type;
TYPE c_rec_type IS RECORD
    (deptno          emp.deptno%TYPE,
     ename           emp.ename%TYPE,
     hiredate        emp.hiredate%TYPE,
     record_id       INTEGER);
c_rec              c_rec_type;
v_sql              VARCHAR2 (4000);
BEGIN
v_sql :=
'SELECT deptno, ename, hiredate, record_id
   FROM   (SELECT deptno, ename, hiredate,
                  ROW_NUMBER() OVER
                    (ORDER BY hiredate)
                    AS record_id
          FROM    emp)
   WHERE record_id >= 2
   AND    record_id <= 5';
OPEN c_my FOR v_sql;
LOOP
    FETCH c_my INTO c_rec;
    EXIT WHEN c_my%NOTFOUND;
    DBMS_OUTPUT.PUT_LINE (c_rec.ename);
END LOOP;
END;
However, you stated that you need it for selecting the correct
range of records for pagination on a website. For that, you
will want something more like this:
CREATE OR REPLACE PACKAGE package_name
AS
TYPE c_my_type     IS     REF cursor;
PROCEDURE procedure_name
    (c_my            IN OUT c_my_type,
     p_record_id1    IN     NUMBER DEFAULT 1,
     p_record_id2    IN     NUMBER DEFAULT 4);
END package_name;
CREATE OR REPLACE PACKAGE BODY package_name
AS
PROCEDURE procedure_name
    (c_my            IN OUT c_my_type,
     p_record_id1    IN     NUMBER DEFAULT 1,
     p_record_id2    IN     NUMBER DEFAULT 4)
IS
    v_sql                   VARCHAR2 (4000);
BEGIN
    v_sql :=
        'SELECT deptno, ename, hiredate, record_id'
    || ' FROM   (SELECT deptno, ename, hiredate,'
    ||                ' ROW_NUMBER() OVER'
    ||                  ' (ORDER BY hiredate)'
    ||                  ' AS record_id'
    || ' FROM    emp)'
    || ' WHERE record_id >= :a'
    || ' AND    record_id <= :b';
    OPEN c_my FOR v_sql
    USING p_record_id1, p_record_id2;
END procedure_name;
END package_name;

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
Dikshit

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

Pl/sql function body returning SQL query - Print function

Hello all,
I have pl/sql function body returning SQL query for my reports for my new project that I am developing. We dont have any BI tool or anything for APEX so we use Oracle reports to get the same reports to be printed in PDF format. I had been using SQL function for Reports all these days and grabbing the data using SQL query was easy in Oracle reports. But this time we had atleast 8 fields in search criteria and hence I thouhgt PL/sql function body returning SQL query could be something easy to handle that scenario. We have 11 such reports in our project. Now when we tried to use the same PL/sql function to oracle reports , I was told by one of our Oracle reports expert, that we have to write it into functions and use it in SQL query to get the Reports in Oracle reports. Is there any Easy way to convert the same Pl/SQL function or get a PDF format of the same report in APEX without going thru the much pains of rewriting the whole SQL Query.
thank you

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,
Sumana

Does 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
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 ||'
elsif (:P102_min_value is null and :P102_max_value is not 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_max_value ||'
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:
failed to parse SQL query:
ORA-00936: missing expression

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;
END;Cheers

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?
