Need to concat lines to a single column

Hi all

Some examples of data.

col1 col2 col3

125 200 abc

126 200 def

127 200 IGS

128 210 homeless

129 rte 210

130 211 uiy

I need output like this.

col2 col3

200 abc, def, ghi

210 homeless, rte

uiy 211

I need data with order of col1

Could you please let me know how to build the query for this.

Thanks in advance.

Hello

Use the function of aggregation LISTAGG, like this:

SELECT col2

LISTAGG (col3, ",") THE Group (ORDER BY col1) AS col3_list,

FROM table_x

GROUP BY col2

;

This requires that you use Oracle 11.2 or greater.

The generic term for this is the String aggregation.

For more on the aggregation of the chain, including how to do this in earlier versions of Oracle, see ORACLE-BASE - String aggregation Techniques

Convert lines to a single column

Hi all

Need help, I have a table where I want the output to a single column

ex: Select in t1. *
the query result_

rownum col_1
1 8217
2 6037
3-5368
4 5543

I want the result to be: * 8217,6037,5368,5543,5232 *.

Thank you for your help in advance.

I search the web but couldn't find a solution that is easily understandable.

WM_CONCAT is not documented, so not everyone would want to use it in production code.
However, SYS_CONNECT_BY_PATH might work:

SQL> create table t as
  2  select 1 rn, 8217 count_1 from dual union
  3  select 2, 6037 from dual union
  4  select 3, 5368 from dual union
  5  select 4, 5543 from dual union
  6  select 5, 5232  from dual;

Table created.

SQL> select * from t;

       RN    COUNT_1
--------- ----------
        1       8217
        2       6037

Create views of data from multiple lines in a single column shows
Hi all - it's probably posted in the wrong forum, but I couldn't find that was right.

I'm almost a perfect beginner in sql, but I have a need to create a view that can be expanded to 10g (which effectively runs the volumes are likely to be high) who will do the following.

Authentic table with columns Parent_code, Child_code
Parent_Code Child_Code
1000-2000
1000-3000
1000-4000
2000 3000
2000-5000

(note that Parents may have several children and a child can have multiple parents!)

What I have to finish with in my opinion is the following

Child_Code Parent_List
' 2000 ' 1000 (3).
3000 "1000 (3), 2000 (2)"
' 4000 ' 1000 (3).
"5000 ' 2000 (2)"

Note the number in parentheses is the number of children whose parent's - IE in the original parent a 1000, 3 table lines (one for each child)

This point of view should be used as a quick glance upward (on the children's code) for a report of business objects.

Is there someone who could you PLEASE, PLEASE help me quickly on what I have very little time to find a solution?
Hello

You can test these:
```
select child_code
     , ltrim(sys_connect_by_path(parent_info,', '), ', ') as parent_list
from (
  select child_code
       , to_char(parent_code) ||
         ' (' ||
         count(*) over(partition by parent_code) ||
         ')' as parent_info
       , row_number() over(partition by child_code order by parent_code) rn
  from your_table
)
where connect_by_isleaf = 1
connect by prior rn = rn-1
       and prior child_code = child_code
start with rn = 1
;
```
```
select child_code,
       rtrim(
         extract(
           xmlagg(xmlelement("e",parent_info||', ') order by parent_info)
         , '//text()'
         )
       , ', '
       ) as parent_list
from (
  select child_code,
         to_char(parent_code) ||
         ' (' ||
         count(*) over(partition by parent_code) ||
         ')' as parent_info
  from your_table
)
group by child_code
;
```
What you need is called 'chain aggregation '.

LISTAGG is not available in 11.1. It was introduced in 11.2.

In any case, XML solution:

Selection of Pixel single column, then paste...

Hello
This might look like a very unusual request, but I was upset to find the answer.
In a given photographic image, I would choose a single pixel in each row of pixels, running up and down in a columnof a pixel. Then, I want to eliminate (Cup) nothing else on the Web with the exception of the one column of selected pixels. From there, I would take the pixel selected in each line and copy the pixel color on each line on the left and right of the pixel selected.
The end result is that I have a series of horizontal lines of pixels height of one color (based on the color of the selected pixel) through the image of left and right.
Looking at this picture:
Select a single pixel on each line in a single column-
xxxxxx XXXXXXS
xxxxxx XXXXXXS
xxxxxx XXXXXXS
Remove/cut everything except the selected pixels in only one column-
...... S......
...... S......
...... S......
Now, on each line, copy single pixel selected to the left and the right of the selection, to the extent of the canvas-

Interesting challenge or Easy-Peasey?
Thank you!

Easy. Use the brand single pixel tool to select a line of pixels. Cmd/Ctrl-J to copy pixels into a new layer. CTRL/cmd-click on the layer icon to select these pixels. CTRL/cmd-T to turn those pixels on the width of the image.

Single line based on two columns and a single column
Dear members,

I have a table that contains duplicate rows, for which a request should be able to extract the unique row in the table. Here the unique is not based on a single column, but it should be in two columns and also check on the uniqueness on a column.

create table addr (varchar2 (10) firstname, lastname varchar2 (10), area varchar2 (3));

insert into values addr ('bob', 'james', 1');
insert into values addr ('bob', 'james', 1');

insert into values addr ('harry', 'bert', ' 1');
insert into values addr ('jimmy', 'bert', ' 1');

insert into values addr ('sam', 'mac', '1');
insert into values addr ('sam', 'Knight', '1');

insert into values addr ('tom', 'sand', '1');
insert into values addr ("cat", "mud", "1");

The query output must contain 3 lines.

Bob - james
Harry - bert or jimmy - bert [or the other of them], but not both
-Mac or sam - Sam Knight [or the other of them], but not both
Tom - sand
Cat - mud

SELECT firstname, lastname as total area WHERE addr = '1' GROUP by firstname, lastname; It takes no duplication of single column...

Remove the clicked point of Listbox (single column)

Hello

It seems a lot of posts on clear lines of the programmatically multicolumn listbox but not the only column listboxes.

Woth the help of Martins and GerdW, helped me build a subset of a ListBox with items clicked in a reference list

Make a table of items clicked in a list

. How it adds a feature to delete just in case rather than the deletion of the entire list and do it all over again.

Thanks in advance.

Have an array of strings to the "REF" enter in the list box and store it on a shift register. When you remove an item (for example, for an event), remove this item from the list (using the removal of the table) and write back to the property Ref of the listbox. A single-column list box works exactly the same way as a multicolumn listbox.

(Excuse the broken links to properties - what happens when you create an excerpt)

Hello Muzz,

Perhaps the example of human Chen reveals a design error.
If a student has a 'teacher_id' "teacher" FK and FK for "emp" becaue each teacher is an EMP, I guess that the correct design would be to have only the FK of 'teacher' and to have another pointing to the 'emp' table in the 'teacher' tabe FK

But we can imagine comical situations...
CREATE TABLE PEOPLE (id NUMBER of KEY PRIMARY, name VARCHAR2 (20 CHAR),...);
CREATE TABLE SCIENTIST (id people KEY PRIMARY NUMBER (id) REFERENCES, discipline VARCHAR2 (20 CHAR),...);
CREATE TABLE POLICEMAN (id REFERENCES to KEY PRIMARY NUMBER (id), hire_date people DATE,...);

First table = all.
2nd: a subset of the first, with people having the profile of 'scientific '...
3rd: a subset of the first, with people being a policeman.
It might be people first table and in none of the 2nd and 3rd, 1st and 2nd, 1st and 3rd only or in the 3 tables.

Then we can have a fourth table of 'something' referring to a person who must be a scientist and a police officer.

Here is a sqlplus session illustrating; the last piece: I try inserting several lines in xxxx, only the last is accepted.

SQL > CREATE TABLE PEOPLE (id NUMBER of the PRIMARY KEY, name VARCHAR2 (20 CHAR));
Table created.

SQL > CREATE TABLE SCIENTIST (people of REFERENCES of KEY PRIMARY NUMBER id (id), discipline VARCHAR2 (20 CHAR));
Table created.

SQL > CREATE TABLE POLICEMAN (people of REFERENCES of KEY PRIMARY NUMBER id (id), DATE hire_date);
Table created.

SQL > CREATE TABLE XXXX (id PRIMARY KEY NUMBER, people_id NUMBER, any other VARCHAR2 (30 CHAR));
Table created.

SQL > ALTER TABLE ADD CONSTRAiNT fk_xxsci FOREIGN KEY (people_id) scientific xxxx REFERENCES (id);
Modified table.

SQL > ALTER TABLE ADD CONSTRAiNT fk_xxpol FOREIGN KEY (people_id) police xxxx REFERENCES (id);
Modified table.

SQL > INSERT INTO person VALUES (100, 'John');
1 line of creation.

SQL > INSERT INTO person VALUES (120, 'Mary');
1 line of creation.

SQL > INSERT INTO person VALUES (103, 'Tom');
1 line of creation.

SQL > INSERT INTO person VALUES (123, "Bruno");
1 line of creation.

SQL > INSERT INTO VALUES of scientific (120, 'Chemistry');
1 line of creation.

SQL > INSERT INTO scientific VALUES (123, 'Mathematics');
1 line of creation.

SQL > INSERT INTO VALUES of policeman (103, DATE ' 2001-04-01');
1 line of creation.

SQL > INSERT INTO VALUES of policeman (123, DATE ' 1998-07-01');
1 line of creation.

SQL > INSERT INTO xxxx VALUES (1, 456, "nothing");
ERROR on line 1:
