Analytical function - return 2 values

I don't know I need to use an analytical function to do this, I can't do things. I appreciate the help.
Statements of table and insert:

create table TST_CK
(
DOC_ID NUMBER(6)      not null,
ROW_SEQ_NBR NUMBER(6) not null,
IND_VALUE VARCHAR2(2) null
)
INSERT INTO TST_CK VALUES ('1','6',NULL);
INSERT INTO TST_CK VALUES ('1','5',NULL);
INSERT INTO TST_CK VALUES ('1','4','T');
INSERT INTO TST_CK VALUES ('1','3','R');
INSERT INTO TST_CK VALUES ('1','9',NULL);
INSERT INTO TST_CK VALUES ('1','10',NULL);
INSERT INTO TST_CK VALUES ('1','7','T');
INSERT INTO TST_CK VALUES ('1','8','R');
INSERT INTO TST_CK VALUES ('2','1',NULL);
INSERT INTO TST_CK VALUES ('2','2',NULL);
INSERT INTO TST_CK VALUES ('2','3','T');
INSERT INTO TST_CK VALUES ('2','4','R');
INSERT INTO TST_CK VALUES ('2','5',NULL);
INSERT INTO TST_CK VALUES ('2','6',NULL);
INSERT INTO TST_CK VALUES ('2','7','T');
INSERT INTO TST_CK VALUES ('2','8','R');
INSERT INTO TST_CK VALUES ('4','1',NULL);
INSERT INTO TST_CK VALUES ('4','2',NULL);
INSERT INTO TST_CK VALUES ('4','3','X1');
INSERT INTO TST_CK VALUES ('4','4',NULL);
INSERT INTO TST_CK VALUES ('4','5',NULL);
INSERT INTO TST_CK VALUES ('4','6',NULL);
INSERT INTO TST_CK VALUES ('4','7','T');
INSERT INTO TST_CK VALUES ('4','8','R');
INSERT INTO TST_CK VALUES ('4','9',NULL);
INSERT INTO TST_CK VALUES ('4','10',NULL);
INSERT INTO TST_CK VALUES ('4','11',NULL);
INSERT INTO TST_CK VALUES ('4','12',NULL);
INSERT INTO TST_CK VALUES ('4','13','T');
INSERT INTO TST_CK VALUES ('4','14','R');
INSERT INTO TST_CK VALUES ('4','15',NULL);
INSERT INTO TST_CK VALUES ('4','16',NULL);
COMMIT;

Here is what I tried that gets me close:

SELECT MAX (TST_CK.DOC_ID), MAX (TST_CK.ROW_SEQ_NBR), TST_CK.IND_VALUE
  FROM ASAP.TST_CK TST_CK
 WHERE (TST_CK.IND_VALUE IS NOT NULL)
GROUP BY TST_CK.IND_VALUE
ORDER BY 2 ASC

Here is my desired outcome:

CV_1      CV_2

 T           R

Or even better result would be:

concat(CV_1,CV_2)

Result:

T,R

Thanks for looking

GMoney says:
Basically, I just need to make sure what I captures the last T and R entered in the column

Still not clear. You want to find the last two lines (function ROW_SEQ_NBR) where IND_VALUE is 't' & 'R', right? If so:

with t as (
           select  doc_id,
                   row_seq_nbr,
                   ind_value,
                   row_number() over(partition by ind_value order by row_seq_nbr desc) rn
             from  tst_ck a
             where ind_value in ('T','R')
          )
select  doc_id,
        row_seq_nbr,
        ind_value
  from  t
  where rn = 1
/ 

    DOC_ID ROW_SEQ_NBR IN
---------- ----------- --
         4          14 R
         4          13 T

Function return undefined values

My function returns undefined values. It seems that the return of the function statement is executed before the database is queried and values are assigned to variables. If I do an alert within the loop for () I get the correct values from the database, but these values are not affected before excecuting the return statement function. How can I do this differently?

function getColumnNames(table){
    var rs1, rs2, rs3, rs4, rs5;
    db.transaction(function (tx) {
        tx.executeSql("SELECT * FROM schema WHERE table_name=?",[table], function(ax, results){
            var size = results.rows.length, i;
            var item;
            for (i = 0; i < size; i++){
                item = results.rows.item(i);
                rs1 = item.col1;
                rs2 = item.col2;
                rs3 = item.col3;
                rs4 = item.col4;
                rs5 = item.col5;
                                alert(rs1); //correct value is returned here
            }
        });
    });
    return [rs1, rs2, rs3, rs4, rs5];
}

Hey Fabian,.

You are quite correct that the return statement is executed before the database returns the results. There are ongoing asynchronous calls. You can set breakpoints in JavaScript code to see what is happening. You can correct the problem by using function callbacks. I edited your code below to use the callback functions - there might be a few typos, but the general approach should be wooded.

function getColumnNames(table, callback){
    var rs1, rs2, rs3, rs4, rs5;
    db.transaction(function (tx) {
        tx.executeSql("SELECT * FROM schema WHERE table_name=?",[table], function(ax, results){
            var size = results.rows.length, i;
            var item;
            for (i = 0; i < size; i++){
                item = results.rows.item(i);
                rs1 = item.col1;
                rs2 = item.col2;
                rs3 = item.col3;
                rs4 = item.col4;
                rs5 = item.col5;
                    alert(rs5); //correct values are being returned
                callback([rs1, rs2, rs3, rs4, rs5]);
            }
        });
    });
}

// example of how to call getColumnNames with callback
getColumnNames('importantTable', function (result)
{
    console.log(result);
});

// alternative version
function onCallback(result)
{
    console.log(result);
}

getColumnNames('importantTable', onCallback);

I hope this helps.

See you soon,.

Back AFTER using the exception block is fine as long as your code actually REACHED the exception block.

When there are no errors, then your code will not enter the exception block, but you still NEED to return a value, since it is what functions a function wants to return a value, that's what the functions are made for.

Spot the differences between the following 3 functions. Understand how they work.

The first function has only a return in the exception block but runs correctly. Result: error, because the back is missing in the code block.

The second function has a return in the exception block and one in the block of code and runs correctly. Result: no error, because the return is not missing in the code block.

The third function has a return in the exception block and one in the block of code and is forced into an error. Result: no error, because the return of the exception handler is used (instead of retriggering of the error, which you would normally do).

ORA-06503: PL/SQL: function returned no value
Hi guys,.
I wrote a function that returns the number of quarter for a given date.
Here's the function

FUNCTION to CREATE or REPLACE fn_get_quarter
(p_date DATE)
RETURN NUMBER
AS
v_qtr NUMBER;
BEGIN
Select TO_CHAR (p_date, 'Q')
IN v_qtr
DOUBLE;
dbms_output.put_line (' it's quarter ' | v_qtr);
END;

It compiled without error.

Here is the test case that I wrote

DECLARE
p_date DATE: = TO_DATE('12/22/2009','MM/DD/YYYY');
v_qtr NUMBER;
BEGIN
v_qtr: = fn_get_quarter (p_date);
END;

When I run the present, I get the following error.

ORA-06503: PL/SQL: function returned no value
ORA-06512: at "GPS_FVO. FN_GET_QUARTER', line 13
ORA-06512: at line 7

But surprisingly, I get the result.

Please suggest and let me know how to get rid of this error and why I get this error.

Thanks in advance.

FIRST analytical functions returns the null line
The following query returns a null line when there is no such thing as a line for the predicate. Is it a bug or expected behaviour. If so what is the meaning of the null row, is it not logical?

Hello

user4900730 wrote:
Moreover, in my example how I distinguish the case where a line really exists, but the column is null when there is no such thing as a line and the FIRST function returns the same value null? Hopefullly I should be able to do it in a single SQL and know the difference?

COUNT (*) > 0, but COUNT (col_x) = 0, then there is a line, but col_x happened to be null.

For example, the following query shows that there is 1 row in the group with the lowest name ("ADAMS"), but the column comm in all ranks of this group is null:
```
SELECT     COUNT (*)    KEEP (DENSE_RANK FIRST ORDER BY ename)
                          AS total_cnt
,     COUNT (comm) KEEP (DENSE_RANK FIRST ORDER BY ename)
                          AS comm_cnt
FROM     scott.emp
;
```
Output:
```
 TOTAL_CNT   COMM_CNT
---------- ----------
         1          0
```
The employee whose highest name ("WARD") has a number in the comm column.

Function - return multiple values in a concatenated string
Hello

Is it possible for a function return a concatenated string (combining more than one number). I'm trying to return the purchase by the introduction and invoice_id number and code order number, but an invoice_id can have several PO with the same code number. I want to concatenate the PO numbers with commas, for example

10124, 10090, 10987

At the present time, the function returns NULL for those cases that have more than one purchase order number.

Thank you
```
func_get_po(i.invoice_id, cc.code_combination_id) "PO No",
func_get_po_requester(i.invoice_id, cc.code_combination_id, func_get_po(i.invoice_id, cc.code_combination_id)) "PO Requester",
```
Of course, this can be done without any problem.
If it returns NULL, then you must debug function and check the operating logic. I know that it will take a little of your time, but not problems with the logic of syntax and concatenation.

APEX 4.0.1: $v () function returns multiple values for the box?
Hello

I have a report that uses apex_item.checkbox (...) to generate the check box. This report correctly displays a check box for each line. The source code that is generated in the html page is:
< input type = "checkbox" name = "f01" value = "202" id = "P1_CHECKBOX" / >
...
...
< input type = "checkbox" name = "f01" value = "220" id = "P1_CHECKBOX" / >
...
...
< input type = "checkbox" name = "f01" value = "210" id = "P1_CHECKBOX" / >
...
...

I want to use the javascript function $v () to get the values of the enabled check box. I thought that the return of this function all the checked values separated by ':' but I noticed that my code alert ($v ('P1_CHECKBOX')); return whenever the value of the first checkbox if it is checked.
It returns '202' if the first box is checked, but nothing, if only the second checkbox is checked and '202' if the box of the first and the second is checked.
Hello

first of all, $v, $x and $s are supposed to not work for items on the page, not the columns in a table or manually generated HTML elements.

Secondly, I think that your HTML code is not correct, because each of your boxes has the same ID. But the ID must be unique in the DOM of the browser tree. Thus the different box should actually named P1_CHECKBOX_1... P1_CHECKBOX_3. Just look at what is actually generated for a page element real checkbox. BTW, I think that you should not name the checkbox as part of page elements, because they are not actually page elements. I think that this could be confusing for other developers.

Hope that helps

I have fully commented goal no. Data Exception not found top check if she is to return null when no record is found.

But he was wrong in not found exception when there is no data record.

But when run sql separately he showed zero records without don't raise the no found error of data.

He would not even through the loop fi... Please correct me if I did something wrong

 if ( v_rgmn_grp_path is not null )
   then
      dbms_output.put_line ( ' Circular Loop is formed as shown :'
                             || v_rgmn_grp_path
                           );
   else
      dbms_output.put_line ( ' No Loop is formed.' );
   end if;

You may not assume that v_rgmn_grp_path will retain the NULL value if the query returns no rows. In this case AS the value of the variable is not defined. I suggest yo change:

Select rgmn_path. '/' || gt.rgmn_grp_nam

Select count (*) case when 1 then max(rgmn_path ||) '/' || end of gt.rgmn_grp_nam)

This way NO_DATA_FOUND will not be raised and the v_rgmn_grp_path will be NULL if there is no corresponding line.

How to return two values of a function?
Hi all
I have a function which returns a varchar2 value. This value is used in the SQL of a ref cursor

Now I want this function returns two values. I tried to use varray, but could not accomplish the task.

Can you tell me how can I find the two values from a function? and how this function can be called in a SQL query?

Thank you very much
The query should look like:
```
SELECT v.col.name AS name
     , v.col.flag AS flag
FROM   ( SELECT kk_test_kk(t.somecolumn,t.someothercolumn,42) AS col
         FROM   sometable t ) v;
```
Note that you need to prefix with the name of view inline ('v' in the example) and the expression of the function ('col' in the example).

analytical function and the aggregate function
What are the analytical function and the aggregate function. What is the difference between them?
Hello

Analytic Functions : -.

Analytical functions calculate a value of aggregation based on a group of lines. They differ from aggregate functions because they return several rows for each group. The Group of rows is called a window and is defined by the analytic_clause. For each line, a sliding window of lines is defined. The window determines the range of lines used for the calculations for the current line. Window sizes can be based on a physical number of rows or a logic as the time interval.
Analytical functions are the last set of operations performed in a query with the exception of the last ORDER BY clause. Every joint and every WHERE, GROUP BY and HAVING clauses are met before the analytical functions are handled. As a result, analytic functions can only appear in the select list or the ORDER BY clause.
Analytical functions are commonly used to calculate cumulative aggregates, moving, centered and considered.

Aggregate functions : -.

Aggregate functions return a line of single result based on the groups of lines, rather than on the unique lines. Aggregate functions can appear in selection lists, as well as in the HAVING and ORDER BY clauses. They are commonly used with the GROUP BY clause in a SELECT statement, where Oracle Database splits the rows in a table when asked or seen in groups. In a query that contains a GROUP BY clause, the select list items can be aggregation functions, GROUP BY constant expressions or expressions involving one of them. Oracle applies the functions of aggregation for each group of rows and returns a single result for each group line.
If you omit the GROUP BY clause, Oracle then applies any aggregate functions in the select list for all rows in the table queried or the view. You use aggregate functions in the HAVING clause to eliminate groups of the output based on the results of aggregate functions, rather than the values of the individual lines of the queried table or view.

Let me know if you feel any problem understanding.
Thank you.

Why the different values for an analytic function of the same group/game

I have the suite of table I'll be using.
Select * from table1;
REC_ID | STATUS | DATE_FROM | DATE_TO
1. C | 7 January 2015 |
2. H | December 3, 2014. 6 January 2015
3. H | October 3, 2014. December 2, 2014
4. H | May 30, 2014. October 2, 2014
5. H | May 29, 2014 | May 29, 2014
6. H | April 16, 2014 | May 28, 2014
7. H | Tuesday, April 25, 2007 April 15, 2014
INSERT statement if you need.
TOGETHER TO DEFINE
CREATE THE TABLE1 TABLE:
(
NUMBER OF REC_ID,
VARCHAR2 (1 BYTE) STATUS NOT NULL,.
DATE_FROM DATE NOT NULL,
DATE OF DATE_TO
);
Insert into TABLE1
(REC_ID, STATUS, DATE_FROM)
Values
(1, 'C', TO_DATE (7 JANUARY 2015 00:00:00 ',' DD/MM/YYYY HH24:MI:SS'));))
Insert into TABLE1
(REC_ID, STATUS, DATE_FROM, DATE_TO)
Values
(2, 'H', TO_DATE (3 DECEMBER 2014 00:00:00 ',' DD/MM/YYYY HH24:MI:SS'), TO_DATE (6 JANUARY 2015 00:00:00 ',' DD/MM/YYYY HH24:MI:SS'));))
Insert into TABLE1
(REC_ID, STATUS, DATE_FROM, DATE_TO)
Values
(3, 'H', TO_DATE (3 OCTOBER 2014 00:00:00 ',' DD/MM/YYYY HH24:MI:SS'), TO_DATE (2 DECEMBER 2014 00:00:00 ',' DD/MM/YYYY HH24:MI:SS'));))
Insert into TABLE1
(REC_ID, STATUS, DATE_FROM, DATE_TO)
Values
(4, 'H', TO_DATE (MAY 30, 2014 00:00:00 ',' DD/MM/YYYY HH24:MI:SS'), TO_DATE (2 OCTOBER 2014 00:00:00 ',' DD/MM/YYYY HH24:MI:SS'));))
Insert into TABLE1

Values
(5, 'H', TO_DATE (29 MAY 2014 00:00:00 ',' DD/MM/YYYY HH24:MI:SS'), TO_DATE (29 MAY 2014 00:00:00 ',' DD/MM/YYYY HH24:MI:SS'));))
Insert into TABLE1
(REC_ID, STATUS, DATE_FROM, DATE_TO)
Values
(6, 'H', TO_DATE (APRIL 16, 2014 00:00:00 ',' DD/MM/YYYY HH24:MI:SS'), TO_DATE (28 MAY 2014 00:00:00 ',' DD/MM/YYYY HH24:MI:SS'));))
Insert into TABLE1
(REC_ID, STATUS, DATE_FROM, DATE_TO)
Values
(7, 'H', TO_DATE (APRIL 25, 2007 00:00:00 ',' DD/MM/YYYY HH24:MI:SS'), TO_DATE (APRIL 15, 2014 00:00:00 ',' DD/MM/YYYY HH24:MI:SS'));))
COMMIT;
I will exercise more analytical query...
Select rec_id date_from, date_to, status,
min (date_from) over (partition by order of status by date_from desc) min_dt_from_grp,
ROW_NUMBER() over (partition by order of status by date_from desc) rownumberdesc,
ROW_NUMBER() over (partition by order of status by ASC date_from) rownumberasc
FROM table1;
the query result
REC_ID | DATE_FROM | DATE_TO | STATUS | MIN_DT_FROM_GRP | ROWNUMBERDESC | ROWNUMBERASC
1. 7 January 2015 | C | 7 January 2015 | 1. 1
2. December 3, 2014. 6 January 2015 | H | December 3, 2014. 1. 6
3. October 3, 2014. December 2, 2014 | H | October 3, 2014. 2. 5
4. May 30, 2014. October 2, 2014 | H | May 30, 2014. 3. 4
5. May 29, 2014 | May 29, 2014 | H | May 29, 2014 | 4. 3
6. April 16, 2014 | May 28, 2014. H | April 16, 2014 | 5. 2
7. Tuesday, April 25, 2007 April 15, 2014. H | Tuesday, April 25, 2007 6. 1
If you look at the output above, it dates back in the min_dt_from_grp column.
MY question is if the analytical function calculates for a particular/set group, which is by statute and for what min (date_from) partition is 25-apr-2007 for the GROUP H (Status column), then why I have different values returned by the query above in the min_dt_from_grp column.

Hello

Because you have specified an ORDER BY clause for the analytical function. In doing so, you calculate the rows on a window. Since you have not specified a windowing clause, the default applies:

RANGE BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW

Return multiple values from a function in a SELECT statement
I hope I've provided enough information here. If not, let me know what I'm missing.

I create a view that will combine the information from several tables. Most are pretty simple, but there are a couple of columns in the view that I need to get by running a function within a package. Even if this is quite simple (I have a function named action_date in a package called rp, for example, that I can use to return the date that I need through SOME rp.action_date (sequence_number).

Here is the question: I really need to return several bits of information of the same record (not only action_date, but also action_office, action_value, etc.)-a join of the tables will work not here, as I will explain below. I can, of course, perform a function separate for each statement, but this is obviously inefficient. Within the select statement of the view, however, I don't know how each of the values that I need to get back.

For example, right now, I have:

Table 1:
sequence_number NUMBER (10),
name varchar (30),
...

Table2:
Table1_seq NUMBER (10),
action_seq NUMBER (10),
action_date DATE,
action_office VARCHAR (3),
action_value VARCHAR (60),
...

I can't just simply join Table1 and Table2 because I have to perform processing in order to determine the rows returned matching, I really need to select. If the package opens a cursor and treats each line until it finds the one I need.

The following works but is ineffective since all calls to the package returns the columns of the same record. I don't know how to put all the values that I need in the SELECT statement.
CREATE VIEW all_this_stuff AS
SELECT sequence_number, name,
RP.action_date (sequence_number) action_date,
RP.action_office (sequence_number) action_office,
RP.action_value (sequence_number) action_value
FROM table1

Is there a way to return multiple values in my SELECT statement or I'm going about this all wrong?

Any suggestions?

Thank you very much!
Hello

What you want is a Query of Top - N , what you can do using the ROW_NUMBER analytic function in a subquery, like this:
```
WITH     got_rnum     AS
(
     SELECT     action_seq, action_dt, action_office, action_type, action_value
     ,     ROW_NUMBER () OVER ( ORDER BY  action_date
                               ,            action_seq
                         ,            action_serial
                       ) AS rnum
     FROM     table2
     WHERE     action_code     = 'AB'
     AND     action_office     LIKE 'E'     -- Is this right?
)
SELECT     action_seq, action_dt, action_office, action_type, action_value
FROM     got_rnum
WHERE     rnum     = 1
;
```
As written, this returns a single line (at most).
I suspect you'll actually get a rank for each group , where a group is defined by a value in a table in which you join.
In this case, add a PARTITION BY clause to the ROW_NUMBER function.
If post you a small example of data (CREATE TABLE and INSERT statements), I could show you exactly how.
As I don't have your tables, I'll show you the use of the tables in the scott schema.
This is a view containing data in the scott.dept table and also to scott.emp, but only for the highest employee in each Department (in other words, the employee whose oldest hire date). If there be a tie for the first hire date, while the candidate with the lowest empno is selected.
```
CREATE OR REPLACE VIEW     senior_emp
AS
WITH     got_rnum     AS
(
     SELECT     d.deptno
     ,     d.dname
     ,     e.empno
     ,     e.ename
     ,     e.hiredate
     ,     ROW_NUMBER () OVER ( PARTITION BY  d.deptno
                               ORDER BY          e.hiredate
                         ,                e.empno
                       ) AS rnum
     FROM     scott.dept     d
     JOIN     scott.emp     e     ON     d.deptno     = e.deptno
)
SELECT     deptno
,     dname
,     empno
,     ename
,     hiredate
FROM     got_rnum
WHERE     rnum     = 1
;

SELECT     *
FROM     senior_emp
;
```
Output:
```
.    DEPTNO DNAME               EMPNO ENAME      HIREDATE
---------- -------------- ---------- ---------- ---------
        10 ACCOUNTING           7782 CLARK      09-JUN-81
        20 RESEARCH             7369 SMITH      17-DEC-80
        30 SALES                7499 ALLEN      20-FEB-81
```
Moreover, one of the conditions to the query you posted has been
```
action_office     LIKE 'E'
```
which equals
```
action_office     = 'E'
```
(AS is always equivalent to = if the string that follows AS does not contain the winning cards.)
Did you mean say that or did you mean something like this:
```
action_office     LIKE 'E%'
```
Instead?
