convert a single column in lines

Hi gurus,

I have a GBA test table is id and name.

Identification number
name varchar2

data are like

name identity

1 xy
2 xyy
3 mm
4 pp

Now my requirement is to convert the IDs of unique column in lines

i, e my output should be Singel lines like:-1,2,3,4

How to achieve this result.

I have no idea to make this request.

Please help guys.

Thanks in advance.

Oh, wait, now I see:

I think that with clause will not work in this State

You have not the clause at all.

You can omit this part and change t in your own table name
I only used it to generate sample data.
That's why I commented :) - query real, based on the id is generated above: in the query, to indicate what is happening ;)

As Alex has already pointed out:
You only need the part from the line 7 (first example) or line 10 (second example)

Hands a great coffee to Alex

Convert a single column into multiple lines
Hi people,

I have a task to display a single column into multiple lines (for use in LOV)

For Ex:

The column consistes of value such as 98,78,67,68,34,90. -It's a unique column values where none of the values can be ' number that is separated by commas

Then we must view it as

98
78
67
68
34
90
-under the number of lines (no lines can be ' do not number).

Thanks in advance
Try this...
```

Re: Convert a single column string into lines (CSV)
Hi all

I would be grateful for the help here... I don't know it's easy for many, but the research I've done seem to ask for function that do not work in the comic book I'm in.: 10.2.0.5.0

Query is:

SELECT '348419,348420,348421' from DUAL;

Hold out to be:

Select of tb1; *
output:
348419
348420
348421
Of more if you only need the values of o/p in the next line, rather than dealing with each value as separate line, Chr (10) can be used.
If you paste this o/p in excel(.csv/.xls format) each value will be in separate lines and the same technique is very useful for statement of purpose.

with a1 as (SELECT '348419,348420,348421' DOUBLE dat)
Select replace (dat, ',', chr (10)) in a1;

Concerning

Prashant,

You must assign new values to null values. You can use a sequence to produce the figures in this column.

Select max (your_unique_column) from your_table; -find the maximum value of this column, so you can start the sequence of this number.

create sequence seq_for_your_table with XXXX - value max + 1 you have found

Update your_table set your_unique_column = seq_for_your_table.nextval () where your_unique_column is null

You can create a primary key on this column.

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:

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 ('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...

Any suggestions...

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)

Two foreign keys of a table in a single column

Hi gurus
I wonder that can we add two foreign keys of a table on a single column, I think the answer is, but what should be the reason behind this?
Appreciate if someone there explain to me...
Concerning
Muzz

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.

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-
SCOTTS SCOTT
SCOTTS SCOTT
SCOTTS SCOTT
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.

Object Table of XMLType vs single column of XMLType Table
What are the differences between the XMLType table object and a table with a single column of XMLType?

It's

CREATE TABLE XMLType xml_table;

and

CREATE TABLE xml_table (xml_field XMLTYPE);

That should be used and when? Both may be declared to be aware of schema.
The main difference is that an XMLType object array allows the use of the XML DB Repository to store and retrieve XML content.
The relationship between a resource and its content is maintained by a "pointer" (REF XMLType) line in the XMLType table:

http://docs.Oracle.com/CD/E11882_01/AppDev.112/e23094/xdb03usg.htm#ADXDB4223
http://docs.Oracle.com/CD/E11882_01/AppDev.112/e23094/xdb03usg.htm#BJFBDEJE

Tables based on the patterns of XMLType (including the associated nested structure) can also be created automatically through recording scheme, which is very convenient when the pattern becomes complex.
In addition, a registred schema-compliant documents that go into the repository automatically stored in the table by default (see the annotation xdb:defaultTable).
We can also use ACLs to control access to specific rows in a table of object XMLType.

This is not possible with XMLType columns in a relational table.
