Dynamic query, row to column

Hi.
Is any way to select one row as column for any table exists?
I mean some script which have table name and condition as input parameters, and prints column_name || column value;
I have tried to do it, but have some problems.
e.g. have table
create table my_table (column1 number, column2 number, column3 number);
insert into my_table values (1,2,3);It should be something like:
declare
lv_table_name varchar2(40):='MY_TABLE'; /*these are input paremeters*/
lv_condition varchar2(300):='column1=1;/*these are input paremeters*/
begin
/*body*/
end;and output should be like (may use dbms_output)
column1    1
column2    2
column3    3    Script should work for any table.
Does anybody solves task similar to this?

Query rows to column

dear Friends,
i need query row to column
example
1 a data1 data2 data3
2 b data1 data2 data3
output format
1 2 a
data1 data2 data3

Please consider the following when you post a question.
1. New features keep coming in every oracle version so please provide Your Oracle DB Version to get the best possible answer.
You can use the following query and do a copy past of the output.
select * from v$version 2. This forum has a very good Search Feature. Please use that before posting your question. Because for most of the questions
that are asked the answer is already there.
3. We dont know your DB structure or How your Data is. So you need to let us know. The best way would be to give some sample data like this.
I have the following table called sales
with sales
as
      select 1 sales_id, 1 prod_id, 1001 inv_num, 120 qty from dual
      union all
      select 2 sales_id, 1 prod_id, 1002 inv_num, 25 qty from dual
select *
from sales 4. Rather than telling what you want in words its more easier when you give your expected output.
For example in the above sales table, I want to know the total quantity and number of invoice for each product.
The output should look like this
Prod_id   sum_qty   count_inv
1         145       2 5. When ever you get an error message post the entire error message. With the Error Number, The message and the Line number.
6. Next thing is a very important thing to remember. Please post only well formatted code. Unformatted code is very hard to read.
Your code format gets lost when you post it in the Oracle Forum. So in order to preserve it you need to
use the {noformat}{noformat} tags.
The usage of the tag is like this.
<place your code here>\
7. If you are posting a *Performance Related Question*. Please read
   {thread:id=501834} and {thread:id=863295}.
   Following those guide will be very helpful.
8. Please keep in mind that this is a public forum. Here No question is URGENT.
   So use of words like *URGENT* or *ASAP* (As Soon As Possible) are considered to be rude.

Dynamic Query Row Count

Dear HTML Gurus,
I have a SQL Query Region that returns/executes a dynamic SQL Query. Based on the number of rows a particular query returns I want to hide or show a different HTML region. I have searched all over for this kind of functionality and have come up with absolutely nothing. I would think that this would be integrated into HTMLDB because Pagination shows the total number of rows returned. Any help or direction would be wonderful.
Thanks,
James

This is how I would do it:
1. create an (hidden) item,
2. create a computation for that item and run it after submit. This computation could be a function returning the rowcount value into your (hidden) item - rowcount of my dynamic sql.
If my dynamic query is to big to be entered into the computation "container", which accepts only a limited number of characters, then I would slightly change my approach:
3. I would create a function in my schema and and call this function from the computation level - either through a simple sql query (select function(in parameter) from dual) or, again through a function returning a number.
I tested this and it worked.

Dynamically convert rows to columns

I've looked at examples on asktom and here and so far everyone I've seen uses decode() or case() but in all cases you have to know the number of columns.. what if you don't?
For example:
select distinct storenbr, pslocation, monthdate, 0 as avg_tran
from aopschedule.staffing_tran_detail, (select last_day(day) monthdate from days
where day between to_date('02/01/2008','mm/dd/yyyy') and to_date('5/31/2008','mm/dd/yyyy'))
where pslocation = '1110'returns
STORENBR     PSLOCATION     MONTHDATE     AVG_TRAN
34806     1110     2/29/2008     0
34806     1110     3/31/2008     0
34806     1110     4/30/2008     0
34806     1110     5/31/2008     0But the date range is dynamic...
So how do I account for this?
I need this to look like
storenbr     pslocation    feb    mar     apr    may
12345        1234          0      0       0      0
12399        2222          2      1       1      1
...I have Oracle 9i. Thanks

Hi,
As Justin said, the number of columns is fixed when the query is compiled.
Without doing dynamic SQL, you can provide for a worst case. For example, you can write a query that always has columns fro 12 months. If you run the query with parameters such that only three months are needed, the other nine columns will be NULL. This is not especially pretty, but it's relatively easy.
You can do a truly dynamic querry In SQL*Plus. Instead of hard-coding a query such as
SELECT storenbr
, pslocation
, SUM (DECODE (n, 1, cnt)) AS col_1
, SUM (DECODE (n, 2, cnt)) AS col_2
FROM staffing_tran_detail
you can put the text shown in bold above (whether it's two columns, as in the example above, or three, or twelve) into a substitution variable. To define that substitution varibale dyamically, use the SQL*Plus "COLUMN ... NEW_VALUE" command, and run a preliminary query (which can be in the same script) to define the variable. If this involves concatenating multiple short rows of output into one very long row, there are a number of string aggregation techiques, such as the user-defined STRAGG function.
Like Justin said, this is not trivial. If you're serious about doing it, post as much code as you can (such as a query with three hard-coded columns), and ask for help with the next step.

Transposing of queried rows into columns

Hi, i have a query that produces an output of several rows (i.e. no. of days in a month). How do I modify my query so that instead of getting 31 rows for january, I will have one row with 31 columns or values? Thank you.

Thank you very much for your response. You definitely got what i wanted to do but honestly, I'm having a hard time applying this to my query since I am not very familiar with the WITH AS, CONNECT BY LEVEL and the PRIOR commands, coupled with the fact that I have to produce my output ASAP. I have this query:
SELECT A.PLTCODE, A.PLTACTLGEN, A.INPTDATE
    FROM PMC_ACTLGEN A
   WHERE     A.INPTDATE >
                TO_DATE ('10/31/2013 00:00:00', 'MM/DD/YYYY HH24:MI:SS')
         AND A.INPTDATE <
                TO_DATE ('01/01/2014 00:00:00', 'MM/DD/YYYY HH24:MI:SS')
ORDER BY                                                           --
        A.PLTCODE, A.INPTDATE
which produce an output that looks like this:
PLTCODE
PLTACTLGEN
INPTDATE

Dynamic populate rows and columns in adf table

Hi everybody !
I have a query thats returns a unic value !
and I want to populate an af:table with this value !
i need to execute this query to get the values for each columns .... and jump to next row and continue to execute the query for new values of the columns of the new row !!!
in backing bean ... im try to do someting like this :
RichColumn coluna = new RichColumn();
coluna.setId("id");
HtmlOutputText out = new HtmlOutputText();
out.setId("receive");
out.setValue("Contas a Receber");
coluna.getChildren().add(out);
out = new HtmlOutputText();
out.setId("pay");
out.setValue("Contas a Pagar");
coluna.getChildren().add(out);
this.getTableFluxo().getChildren().add(coluna);
but i get the same values for all the rows !!!!

Hi there,
If you use ADF BC you can make transient variable in the View Object and fill it in the get method,every time the
get method is executed you will execute the query and change the value of the new transient variable.
Even better solutions is to extend the query with this extra column and map the table with it.

Alexander

Dynamic SQL rows to column

I have a table something like
                              WHERE    IN
                              Age           18
                              Year           2012,2013
                              Color         Blue
--etc
                              I would like to create a dynamic statement base on this table
                              Dyanmic SQL:
                              WHERE AGE IN (18) and Year IN (2012,2013) and Color IN (‘Blue’)
I am using SQL server 2008 R2. How can I do this using XML path or something

Here you go:
DECLARE @tbl TABLE ([WHERE]   sysname NOT NULL,
   [IN]    nvarchar(200))
INSERT @tbl([WHERE], [IN])
   VALUES ('Age', '18'), ('Year', '2012,2013'), ('Colour', 'Blue,Yellow')
DECLARE @where nvarchar(MAX)
SELECT @where =
   (SELECT [WHERE] + ' IN (' +
CASE WHEN [IN] LIKE '%[^0-9,]%'
   THEN replace(quotename([IN], ''''), ',', ''',''')
   ELSE [IN]
END + ') AND '
FROM   @tbl
FOR XML PATH(''), TYPE).value('.', 'nvarchar(MAX)') + ' 1 = 1'
SELECT @where
However, this is somewhat brittle. I'm assuming that a comma is a list separator; never part of a value searched for. I'm also assume that as long as a value is digits only, it is numeric, else it is a string. This would fail if there is a date value
on the form YYYYMMDD.
Probably you should store metadata somwhere, so that you know the data type of a column.

Dynamic add row/columns to data forms(11.1.1.3) v/s (11.1.2.1)

Hello All,,
There used to be an option in Hyperion planning 11.1.1.3 to Dynamic add rows in data form. I don't see this option in planning 11.1.2.1 ?
Could you please suggest how we can grant right users to add dynamic add rows and columns in data forms? or it is possible in 11.1.2.1 ?
out user want to have a feature of adding row in data forms (planning forms)
Thank you
Edited by: 842804 on Aug 17, 2011 12:49 PM

Do you mean 11.1.2, if so then adhoc web forms really take over from adding rows as they add much more functionality.

Converting rows to columns using dynamic query.

I am trying to use the below code that I founnd on the web to conver rows to columns. the reason that I want to use dynamic query is that the number of rows are not know and changes.
declare
    lv_sql varchar2(32767) := null ;
begin
    lv_sql := 'SELECT Iplineno ';
    for lv_rec in (SELECT distinct vendor from bidtabs where letting = '10021200' and call ='021')

How to accessing current row report column value in Lov Query?

Hi,
which access methods (eg. bind variables, substitutions, ...) for getting the current row report column value can be used in the "Lov Query" property of a report column?
As what I know of and what I have read on the forum there are no bind variables for the report columns. For the "Link Text" property it seems that the column values exist as substitution strings (#COLUMN_NAME#). But they don't work in the Lov Query. => And would be good because of a hard parse each time the Lov query is executed.
The following post (Re: Simulating a correlated sub query in lov
is showing a solution to use package variables for temporary storage of the referenced value, but the only problem with that solution is that if a new record is added with the "Add rows to tabular form" process the package variable still contains the value from the last queried row! Is there a way (variable, APEX package, ...) to determine if the lov query is executed for a new record so that the package can return null?
I know that I could write the package in a way that the value is immediately cleared when lov_pkg.keyval is called (one time read), but then I would have to create several variables if I'm accessing the value multiple times in the query or in another query => I think an one time read solution would be very obscurely.
Thanks for your help

Hi Patrick,
I agree that it's a waste to continually use Ajax to go back to the server to get the contents of a dynamic select list.
There are no bind variables for any row item - but what you do have, as per my previous post, is the value of the data entered by the user in the first row. You can pass this into your application process (using get.add("VARIABLENAME", value)), which can use it to retrieve the correct LOV in your Ajax code - this will give you a "bind variable" that your process can use.
What you could do, however, is generate hidden select lists on your page - one for each possible LOV list and replace the contents of the new row's select list with the contents of the appropriate hidden select list. This is easy to do with javascript (using innerHTML functions). Obviously, though, the usefulness of this depends on the number and size of the select lists.
Even if you don't generate them to start with, you can keep a copy of any select lists returned by Ajax in the DOM for use on new rows. So, if you have retrieved a select list, you will have a copy of it in DOM which you can then copy into the new row. If you don't have the list in DOM, use Ajax to get it, store a copy of it and copy it into the new row.
Which method you use will depend on the number/size of select lists needed. If they are few in number and/or size, I would suggest generating hidden lists. If they are large, use Ajax to get them once, store them and then retrieve them from the DOM when needed.
There is another thread here where Arie recommends going to the server every time to make sure you get the most up-to-date data for the lists. If you want to follow this advice, for this reason, use get.add("VARIABLENAME", value) to pass the value to your process. If this is not an issue, you can use one of the other methods I outlined above.

Andy

converting the set of values in one of the columns into the column headings for the entire query.
create TABLE my_tab ( deptno VARCHAR2(5), job VARCHAR2(50), sal NUMBER);
insert into my_tab ( deptno,JOB, sal) values ( 10, 'ANALYST', 23000);
insert into my_tab ( deptno,JOB, sal) values ( 10, 'SALESMAN', 1500);
insert into my_tab ( deptno,JOB, sal) values ( 10, 'CLERK', 3550);
insert into my_tab ( deptno,JOB, sal) values ( 20, 'SALESMAN', 700);
insert into my_tab ( deptno,JOB, sal) values ( 20, 'ANALYST', 4200);
insert into my_tab ( deptno,JOB, sal) values ( 30, 'SALESMAN', 5600);
insert into my_tab ( deptno,JOB, sal) values ( 30, 'CLERK', 12000);
insert into my_tab ( deptno,JOB, sal) values ( 30, 'ANALYST', 19000);
COMMIT;
SELECT * FROM my_tab
DEPTNO ______ JOB ________ SAL
10 ______ ANALYST ________ 23000
10 ______ SALESMAN     ________     1500
10     _______ CLERK     ________     3550
20     _______     SALESMAN ________     700
20     _______     ANALYST     ________ 4200
30     _______     SALESMAN ________     5600
30     _______     CLERK     _______          12000
30     _______ ANALYST     _______     19000
--And I wish to convert it into this structure:
DEPTNO ________ ANALYST ________ SALESMAN _________ CLERK
10      ________     23000 ________     1500     _________     3550
20     ________ 4200 ________     700     _________     NULL
30     ________ 19000 ________     5600     _________     12000
It may be dynamic. i.e Later i inserted more two records into My_tab.
insert into my_tab ( deptno,JOB, sal) values ( 20, 'CLERK', 3400);
insert into my_tab ( deptno,JOB, sal) values ( 30, 'MANAGER', 48000);
So it should be dynamic.
output is like this.
DEPTNO ________ ANALYST ______ SALESMAN ______ CLERK ______ MANAMGER
10           ________ 23000     ______ 1500     ______ 3550     ______     NULL
20          ________ 4200     ______ 700     ______ 3400     ______     NULL
30          ________ 19000     ______ 5600     ______ 12000     ______     48000
Please help me regarding this.
With warm regards,

Hi, Prasanta,
Displaying one column from many rows as many columns on one row is called Pivoting . The following thread shows the basics of how to pivot:
Help for a query to add columns
That example uses the aggregate COUNT function; you'll want SUM (or possibly MIN or MAX) instead.
Getting a dynamic number of columns requires Dynamic SQL . As a simpler alternative to pivoting and dynamic SQL, you might consider String Aggregation , where you concatenate a column from many rows into one big string, to be displayed on one row.
See the following thread for more about string aggregation and other options on pivoting into a variable number of columns:

Need query to convert Single Row Multiple Columns To Multiple rows

Hi,
I have a table with single row like below
Column0 | Column1 | Column2 | Column3 | Column4|
Value0 | Value1 | Value2 | Value3 | Value4 |
Am looking for a query to convert above table data to multiple rows having column name and its value in each row as shown below
Column0 | Value0
Column1 | Value1
Column2 | Value2
Column3 | Value3
Column4 | Value4
Thanks in advance.

Hi ykMohan,
Dynamic UNPIVOT can be applied in this case as well.
CREATE TABLE dbo.T(ID INT,Column0 VARCHAR(99),Column1 VARCHAR(99),Column2 VARCHAR(99),Column3 VARCHAR(99),Column4 VARCHAR(99))
INSERT INTO T VALUES
(1,'Value0','Value1','Value2','Value3','Value4'),
(2,'Value0','Value1','Value2','Value3','Value4');
DECLARE @columns VARCHAR(MAX)
SELECT @columns=
STUFF(
SELECT ','+ COLUMN_NAME FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME ='T' AND TABLE_SCHEMA='dbo' AND Column_name NOT IN('ID') FOR XML PATH('')
),1,1,'')
DECLARE @Sql NVARCHAR(MAX)
SET @Sql =
'SELECT ID, UPT.col,UPT.val FROM T
UNPIVOT
(val FOR col IN('+@columns+')) AS UPT'
EXEC sp_executeSQL @Sql
DROP TABLE T
