Concatenate the result set into a SQL string

Hi, I need help with the concatenation of a result set in order to avoid the duplication of data.

I have 3 tables:

SCRIPT
ID - number PK
DATE - day
TITLE - Varchar2

AUTHOR
A_ID - number PK
A_Name - Varchar2

SCRIPT_AUTHOR
ID - number - PK, FK of Script.ID
A_ID - number PK, FK of Author. A_ID

I need the list of all authors for each script on a single line, for the moment I have the following SQL code:

Select S.Title, SA. A.ID
SCRIPT S, SCRIPT_AUTHOR SA
WHERE SCRIPT.ID = SCRIPT_AUTHOR.ID

and as expected it's returning a dataset as follows:-give me 2 lines in this case for a script:

S.TITLE, SA. A_ID
1, 1
1, 2

What I'm really after is a result set that combines the two authors in this case a file: 1, 1:2, so I don't have 1 line by script.
Scripts can have many authors, and I want to do it for a lot of scripts at a time.

I hit a blank on how to do it, is it possible to do it with SQL?

Thank you very much

p.s. help: Oracle Database 10g Enterprise Edition release 10.2.0.3.0

Hello

This is called 'aggregation of chain.
[AskTom.oracle.com | http://asktom.oracle.com/pls/asktom/f?p=100: 11:0:P11_QUESTION_ID:2196162600402] shows several ways to do so.

I recommend the first, the function defined by the user STRAGG, that you can copy from this page.

Once you have installed STRAGG, your query is simply

Select       S.Title
,       STRAGG (SA.A.ID)     AS sa_id_list
FROM       SCRIPT     S
,       SCRIPT_AUTHOR SA
WHERE       SCRIPT.ID = SCRIPT_AUTHOR.ID
GROUPB BY s.Title;

On Oracle 10 (and more) you can have a similar function, the WM_CONCAT (property WMSYS), already installed.
WM_CONCAT is not documented, so you can't use it in your Production applications.

AF:inputListOfValues sets the value of the first item in the result set when using enter key or tab and component value autosubmit = true

I use JDev 11.1.1.6 and when I type in a value in an af:inputListOfValues element and press enter or the tab key, it will replace the value I entered with the first element in the set of results LOV. If enter a value, simply click on the component af:inputListOfValues it works correctly. If I use the popup and find a value it works properly as well. I have a programmatic view object that contains a single transitional attribute (this is the view object that is used to create the list of the components of the value of) and then I have another object from view based on entities which defines one of its attributes in a list of the attribute value. I tried to use a base object view of entity to create the LOV to and everything works as expected, so I don't know if this is a bug when using programmatic view objects or if I need more code in the VOImpl. In addition, it seems after that first of the value being replaced by the first value in the result set that it will work correctly as well. Here are some excerpts of important code.

Also, it seems that this does not work only if the text entered in the component af:inputListOfValues would have only a single game, returned in the result set. For example, given the result defined in code: Brad, Adam, Aaron, Fred, Charles, Charlie, Jimmy

If we get into Cha, the component works as expected

If we register A, the component works as expected

If we get Jimmy, the component does not work as expected, and returns the first value of results IE. Brad

If we get Fred, the component does not work as expected, and returns the first value of results IE. Brad

I also checked that I get the same behavior in JDev 11.1.1.7

I found a solution to this problem. It seems that, when using a view object programmatic that has a transient as its primary key attribute, you need to override the methods in the ViewObjectImpl so that he knows how to locate the line related to the primary key when the view object records are not in the cache. That's why it would work properly sometimes, but not always. Here are the additional methods that you must override. The logic you use in the retrieveByKey would be on a view view object database object and would be different if you had a primary key consisting of multiple attributes.

@Override
protected Row[] retrieveByKey (ViewRowSetImpl viewRowSetImpl, Key key, int i) {
    return retrieveByKey(viewRowSetImpl, null, key, i, false);
}

@Override
protected Row[] retrieveByKey (ViewRowSetImpl viewRowSetImpl, String string, Key key, int i, boolean b) {

    RowSetIterator usersRowSetIterator = this.createRowSet(null);
    Row[] userRows = usersRowSetIterator.getFilteredRows("UserId", key.getAttribute(this.getAttributeIndexOf("UserId")));
    usersRowSetIterator.closeRowSetIterator();
    return userRows;

}

@Override
protected Row[] retrieveByKey (ViewRowSetImpl viewRowSetImpl, Key key, int i, boolean b) {
    return retrieveByKey(viewRowSetImpl, null, key, i, b);
}

How to exclude the each row of the result set XML declaration?
Hello

I have a table with an XMLTYPE column and would like to SELECT a set of rows. How can I exclude the each row of the result set XML declaration? My query currently looks like this, I am running through Spring JDBC:
SELECT XMLSerialize FROM t1 WHERE XMLEXISTS('$e/Event' PASSING XMLTEXT AS "e") ORDER BY t1.time DESC myschema.event (HAPPY t1.xmltext)

After selecting, in my application I convert each line in a string and concatenate all the rows in a large chain to analyze in a DOM model. I get a parser exception (org.xml.sax.SAXParseException: the target of the processing instruction corresponding to "[xX] [mM] [he's]" is not allowed) because there are several XML statements in my large chain. Of course, I could manually check the string on each line if it starts with the XML declaration, but it would be nicer if I could load the DB does not add it in the first place. Is there a way?

Thank you!
-Daniela
Hello

Some options that I can think of:
```
SELECT XMLSerialize(CONTENT
 XMLtransform(t1.xmltext,
  xmltype('
 
 
')
 )
)
FROM myschema.event t1
WHERE XMLEXISTS('$e/Event' PASSING XMLTEXT AS "e")
ORDER BY t1.time DESC
;
```
or quite simply,.
```
SELECT XMLSerialize(CONTENT
  extract(t1.xmltext,'/')
)
FROM myschema.event t1
WHERE XMLEXISTS('$e/Event' PASSING XMLTEXT AS "e")
ORDER BY t1.time DESC
;
```

Remove duplicates from the result set
Here's a challenge question that I was playing with a my free time during the work.

I assume you have the basic HR example somewhere around (I hope is not in production).

Let's say you want to get employees from the employees table whose name is similar to another employee last name.
The easiest way is to join the two tables with a join condition that checks for the name and employee id. Here's what I came with.

*************

Select e1.last_name, e1.first_name b, e2.last_name c, e2.first_name d
employees employees join e1 e2
on (e1.last_name = e2.employee_id <>e2.last_name and e1.employee_id)
order by one;

************

The above query returns 10 rows. The first and the second are essentially the same. It is similarly, 3 & 4, 5 & 6, 7 and 8 and 9 and 10. The question is: is there a way that allows me to get rid of using only sql duplicate rows from the result set of this query. I sat on it for 15 minutes and I couldn't know. I'll try to watch my completed work once again.
Example:
```
SQL> column a format a10
SQL> column b format a10
SQL> column c format a10
SQL> column d format a10
SQL>
SQL>
SQL> select e1.last_name a , e1.first_name b, e2.last_name c, e2.first_name d
  2  from employees e1 join employees e2
  3  on ( e1.last_name = e2.last_name and e1.employee_id != e2.employee_id)
  4  where e1.employee_id < e2.employee_id
  5  order by a;

How to test a procedure returns the result set

Hello

I have a following code:

AS
type cursorType is ref cursor;
end;

create or replace PROCEDURE GetAllCategories (p_cursor in the Types.cursorType)
AS
Start
Open p_cursor for SELECT * CATEGORY;
end; {color}

I would like to test the procedure of * {color: #000000} visualization output resultset {color} *. How can I do with SQL Developer?
In fact, when select RUN in SQL Developer, I got the following code:

DECLARE
P_CURSOR types.cursorType;
BEGIN

GetAllCategories (P_CURSOR = & gt; P_CURSOR);
END;

When I run it, it is successful but there is no result set displayed. However if I execute SELECT * FROM category only in the SQL Editor, I see the result set in the grid. Then where the result set did when he went through the procedure?

Thanks in advance for any help.

Help with the query to select only one record from the result set in double

Please help with the query. Version of Oracle database we use is 10g R2.

Hello

This sounds like a job for ROW_NUMBER:

WITH got_r_num AS

(

SELECT id, DSB, df, s, sub_sec org

ROW_NUMBER () OVER (PARTITION BY ID.

ORDER BY org

) AS r_num

OF view_x

)

SELECT id, DSB, df, sub_sec s,

OF got_r_num

WHERE r_num = 1

;

He is a Top - N query example, where you choose the elements of N (N = 1 in this case) from the top of an ordered list.

I hope that answers your question.
If not, post a small example of data (CREATE TABLE and INSERT, only relevant columns instructions) to your sample data and the results desired from these data. (I know that you said that you were a view selection. Just for this thread, pretending it is a picture and post simple CREATE TABLE and INSERT statements to simulate your point of view).
Point where the above query is to produce erroneous results, and explain, using specific examples, how you get the right results from data provided in these places. (I didn't quite understand the explanation above. I don't know why you want to

ID ORG DF DRY SUB_SEC

and is not

1234 IS CQ ASIC, ASIC

or

If you change the query at all, post your modified version.
Always say what version of Oracle you are using (for example, 11.2.0.2.0).

This does not work as expected with an aggregation as subquery (see sal_dept), but adds little by little upward in determining the value of the slider by a function (see sel_debt_funct). What is the reason for this behavior? Bug feature?

Facts: Oracle 10.2.0.4

CREATE OR REPLACE FUNCTION get_sal_dept(
    pdeptno IN emp.deptno%TYPE
)
    RETURN emp.sal%TYPE
IS
    lnreturn  emp.sal%TYPE;
BEGIN
    SELECT SUM(sal)
    INTO   lnreturn
    FROM   emp
    WHERE  deptno = pdeptno;

    RETURN lnreturn;
END get_sal_dept;
/

BEGIN
    FOR r_emp IN (SELECT empno
                        ,ename
                        ,sal
                        ,emp.deptno
                        ,sal_dept
                        ,get_sal_dept(emp.deptno) sel_debt_funct
                  FROM   emp
                        ,(SELECT   deptno
                                  ,SUM(sal) sal_dept
                          FROM     emp
                          GROUP BY deptno) x
                  WHERE  emp.deptno = x.deptno)
    LOOP
        UPDATE emp
        SET sal = sal * 1.33
        WHERE  empno = r_emp.empno;

        DBMS_OUTPUT.put_line(r_emp.ename
                             || ': '
                             || r_emp.sal
                             || ' Total Deptno: '
                             || r_emp.deptno
                             || ' by inline aggr:'
                             || r_emp.sal_dept
                             || ' by function:'
                             || r_emp.sel_debt_funct
                            );
    END LOOP;

    ROLLBACK;
END;
/

DROP FUNCTION get_sal_dept
/

If I understand your point, the key concept to understand here is related to "* statement-level Read consistency and coherence of reading at the level of transactions."

From the Manual:
+ "If a SELECTION list contains a function, then the database applies consistency of reading to the statement-level to the level of the SQL statement executed in the PL/SQL function, rather than the parent level SQL code. For example, a function can access a table whose data are changed and committed by another user. For each execution of the function, SELECT a snapshot consistent new reading is established. » +

These two concepts are well explained in the "Oracle® Database Concepts":

Insert a blank line in the result set

Hi friends,

SELECT * FROM EMPLOYEES ORDER BY DEPARTMENT_ID;

As a result of the foregoing, I need to INSERT a blank line in the result for each department_id. for example, the result should resemble the following:

EMP_ID - NAME - SALARY - DEPARTMENT_ID
101 - Albert - 10 000 - 10
102 - Benjamin - 8 000 - 10

103 - Chitra - 10 500 - 20
104 - David - 4 500-20
105 - Elango - 6 000 - 20

106 - faye - 6 000 - 30
107 - Ganga - 9 000 - 30

etc.

I don't want to insert into the table. I need a blank line just on the screen.

Thanks in advance.

LOULOU.

Ask... How to reach the result sets in order?

Let me give a few examples of data first to give an idea of what I am working with:

Oracle: 10g

--Table xTable

NAME             DESC_ID
ALAN                   2 
AMY                    3
BILL                    5
BOB                     7
CARL                   1
CHRIS                  8
DAN                    4
DEREK                 6

So what I try to do is right out of names (ALAN, CHRIS, DAN) in ascending order (according to out of name) and then all the names (AMY, BILL, BOB, CARL, DEREK) in ascending order (according to out name)... and I want all of this in a single result set. So basically the first set of names in alphabetical order, followed by the rest of the names in alphabetical order.

I want the output to look exactly like this:

NAME       DESC_ID     
ALAN               2
CHRIS                8
DAN                  4
AMY                  3
BILL                   5
BOB                    7  
CARL                  1
DEREK                6

I tried the following, but it doesn't seem to work

select distinct a.name, a.desc_id
from xTable,
(select distinct name, desc_id
from xTable
where DESC_ID  in (2,8,4)
order by name
) type1,
(select distinct name, desc_id
from xTable
where DESC_ID  in (1,3,5,6,7)
order by name
) type2
where desc_id in (type1, type2);

The code above seems terribley unefficent and apparently not at the exit of the things in the order I want. Any ideas?

If you have a known list of DESC_ID you could do something like this:

SQL> WITH xTable AS
  2  (
  3          SELECT 'ALAN'   AS NAME, 1 AS TYPE_ID, 2 AS DESC_ID FROM DUAL UNION ALL
  4          SELECT 'AMY'    AS NAME, 2 AS TYPE_ID, 3 AS DESC_ID FROM DUAL UNION ALL
  5          SELECT 'BILL'   AS NAME, 2 AS TYPE_ID, 5 AS DESC_ID FROM DUAL UNION ALL
  6          SELECT 'BOB'    AS NAME, 2 AS TYPE_ID, 7 AS DESC_ID FROM DUAL UNION ALL
  7          SELECT 'CARL'   AS NAME, 2 AS TYPE_ID, 1 AS DESC_ID FROM DUAL UNION ALL
  8          SELECT 'CHRIS'  AS NAME, 1 AS TYPE_ID, 8 AS DESC_ID FROM DUAL UNION ALL
  9          SELECT 'DAN'    AS NAME, 1 AS TYPE_ID, 4 AS DESC_ID FROM DUAL UNION ALL
 10          SELECT 'DEREK'  AS NAME, 2 AS TYPE_ID, 6 AS DESC_ID FROM DUAL
 11  )
 12  SELECT  NAME
 13  ,       DESC_ID
 14  FROM    xTable
 15  ORDER BY
 16          (CASE
 17                  WHEN DESC_ID IN (2,8,4)         THEN 1
 18                  WHEN DESC_ID IN (1,3,5,6,7)     THEN 2
 19          END)
 20  ,       1
 21  /

----- --------------------
ALAN                     2

DEREK                    6

8 rows selected.

Another option would be to use the UNION, but he strikes the table twice instead of once as described above:

SQL> WITH xTable AS
  2  (
  3          SELECT 'ALAN'   AS NAME, 1 AS TYPE_ID, 2 AS DESC_ID FROM DUAL UNION ALL
  4          SELECT 'AMY'    AS NAME, 2 AS TYPE_ID, 3 AS DESC_ID FROM DUAL UNION ALL
  5          SELECT 'BILL'   AS NAME, 2 AS TYPE_ID, 5 AS DESC_ID FROM DUAL UNION ALL
  6          SELECT 'BOB'    AS NAME, 2 AS TYPE_ID, 7 AS DESC_ID FROM DUAL UNION ALL
  7          SELECT 'CARL'   AS NAME, 2 AS TYPE_ID, 1 AS DESC_ID FROM DUAL UNION ALL
  8          SELECT 'CHRIS'  AS NAME, 1 AS TYPE_ID, 8 AS DESC_ID FROM DUAL UNION ALL
  9          SELECT 'DAN'    AS NAME, 1 AS TYPE_ID, 4 AS DESC_ID FROM DUAL UNION ALL
 10          SELECT 'DEREK'  AS NAME, 2 AS TYPE_ID, 6 AS DESC_ID FROM DUAL
 11  )
 12  SELECT  NAME
 13  ,       DESC_ID
 14  FROM
 15  (
 16          SELECT  NAME
 17          ,       DESC_ID
 18          ,       1 AS ORD_COL
 19          FROM    xTable
 20          WHERE   DESC_ID IN (2,8,4)
 21          UNION
 22          SELECT  NAME
 23          ,       DESC_ID
 24          ,       2 AS ORD_COL
 25          FROM    xTable
 26          WHERE   DESC_ID IN (1,3,5,6,7)
 27  )
 28  ORDER BY ORD_COL
 29  ,       NAME
 30  /

How can I show all the results returned by a sql query?
Hi guys,.

I need your help.
Let's say I have a table: TableA. Fields in TableA are aleg, anon, monkeys. The following sentence can return, in general, several rows: select anon from TableA where aleg = somevalue. I would like to show the result of the anon column but no luck. If I try to display the results in a TextArea and the origin is a sql query shows that the first value of the line. I tried to see the like: display text (based in PLSQL) and a block anonymous plsql and coding
DECLARE
v_anon TableA.anon%TYPE;
CURSOR v_cur IS
Select anon from TableA where aleg = somevalue;
BEGIN
OPEN v_cur.
LOOP
SEEK v_cur INTO v_anon;
EXIT WHEN v_cur % NOTFOUND;
: FIELD_IN_FORM: = v_anon;
END LOOP;
CLOSE V_cur;
END;
but in this case, he showed no results.
So the first question is what type of field can I use to show the result. And the second is what can I do to be able to show all the results returned by the query (if more than one line).

get the result set in CSV

How can I get a result set of a table as a comma-separated value? I saw there are dbms_utility.table_to_comma but don't know how to use it.

For example,
Select column_name from user_tab_columns where table_name = "TAB1".

I want to get the result as col1, col2, col3

I'm using Oracle 11 g.

Your help is very appreciated. :)

Hello

in oracle 11, you can use:

select
  LISTAGG(column_name,',') WITHIN GROUP (ORDER BY COLUMN_ID) CSV

from
  user_tab_columns

where
  table_name = 'PBCATCOL'

;

CSV
---------------------------------------------------------------------------------------------------------------------------------------------
PBC_TNAM,PBC_TID,PBC_OWNR,PBC_CNAM,PBC_CID,PBC_LABL,PBC_LPOS,PBC_HDR,PBC_HPOS,PBC_JTFY,PBC_MASK,PBC_CASE,PBC_HGHT,PBC_WDTH,PBC_PTRN,PBC_BMAP,PBC_INIT,PBC_CMNT,PBC_EDIT,PBC_TAG

Kind regards
