Creating Dynamic Column Names at Runtime

I have a dynamic query that I'm running under Portal. I would
like to assign column headings based on the query results.
Example:
Select a.x "a.name_x",
a.y "a.name_y",
a.z "a.name_z"
from a
where a.q = "user input"
I know the above example will not run, but I'm using it to make
the point as to what I would like display as column headings.
TIA
Sean

Hi,
You can try this
select 'col_name1' col1, 'col_name2' col2, ..., 'col_namen' coln
from dual
union all
select col1, col2, ... coln from tbl
then, eg. you're building a report, you can just set each column
heading text to ' '. of course you can use such as
select decode(:var,1,'col_name1',2,'col_name2...)...
This trick is not suitable for multi-page report publishing, cos
the column headings are actually the first line of record.
hope that would help

How to change recordset bahaviour to accept dynamic column names in the where clause

Hi
im using php-mysql and i make a recordset and i want to make the column names in the where clause to be dynamic like
"select id,name from mytable where $tablename-$myvar";
but when i do this my i break the recordset and it disappear
and when i use variables from advanced recordset it only dynamic for the value of the column not for the column name
and when i write the column name to dynamic as above by hand it truns a red exclamation mark on the server behaviour panel
so i think the only way is to change the recordset behaviour is it? if so How to make it accept dynamic column names?
thanks in advance.

As bregent has already explained to you, customizing the recordset code will result in Dreamweaver no longer recognizing the server behavior. This isn't a problem, but it does mean that you need to lay out your dynamic text with the Bindings panel before making any changes. Once you have changed the recordset code, the Bindings panel will no longer recognize the recordset fields.
Using a variable to choose a column name is quite simple, but you need to take some security measures to ensure that the value passed through the query string isn't attempting SQL injection. An effective way of doing this is to create an array of acceptable column names, and check that the value matches.
// create array of acceptable values
$valid = array('column_name1', 'column_name2', 'column_name3');
// if the query string contains an acceptable column name, use it
if (isset($_GET['colname']) && in_array($_GET['colname'], $valid)) {
$col = $GET['colname'];
} else {
// set a default value if the submitted one was invalid
$col = 'column_name1'
You can then use $col directly in the SQL query.

Dynamic column name sql?

I need to do a select statement using dynamic column names. Can it be done WITHOUT building a string to execute the sql?
In other words, I want to use a variable name in the SELECT part of a statement.
Thanks

Properly done, there shouldn't be a great difference in the performance of static and dynamic SQL. Of course, dynamic SQL is a whole lot more complicated to get right. It's also rather at odds with your requirement that column names get passed in dynamically-- if you don't know what columns you're going to select at compile time, you can't use static SQL.
That said, there are a handful of tricks around using Oracle's built-in XML processing functionality to simulate dynamic SQL. This is almost certainly less efficient than doing dynamic SQL in your case, and a whole lot more complicated, but it's technically not dynamic SQL.
The proper response, though, is almost certainly to either
1) figure out how to design the application so that column names need not be passed in at runtime or
2) use dynamic SQL.
If at all possible, option 1 is generally preferable. While there are situations where dynamic SQL is necessary, those tend to be rather rare.

Please follow basic Netiquette and post the DDL we need to answer this. Follow industry and ANSI/ISO standards in your data. You should follow ISO-11179 rules for naming data elements. You should follow ISO-8601 rules for displaying temporal data. We need
to know the data types, keys and constraints on the table. Avoid dialect in favor of ANSI/ISO Standard SQL. And you need to read and download the PDF for:

>> I need to select from a dynamic column name and save the result in a variable, but seem to be having trouble with the values being fed to sp_executesql <<
This is so very, very wrong! A column is an attribute of an entity. The idea that you are so screwed up that you have no idea if you want
the shoe size, the phone number or something else at run time of this entity.
In Software Engineering we have a principle called cohesion that says a model should do one and only one task, have one and only one entry point, and one and only one exit point.
Hey, on a scale from 1 to 10, what color is your favorite letter of the alphabet? Yes, your mindset is that level of sillyity and absurdity.
Do you know that SQL is a declarative language? This family of languages does not use local variables!
Now think about “month_val” and what it means. A month is a temporal unit of measurement, so this is as silly as saying “liter_val” in your code. Why did you use “sp_” on a procedure? It has special meaning in T-SQL.
Think about how silly this is:
SET @month_val = 'Month' + CAST(@month_nbr AS VARCHAR(2));
We do not do display formatting in a query. This is a violation of at the tiered architecture principle. We have a presentation layer. But more than that, the INTERVAL temporal data type is a {year-month} and never just a month. This is fundamental.
We need to see the DDL so we can re-write this mess. Want to fix it or not?

Dynamic column names in Oracle

HI SOS!! calling for help...
i am trying to query the following. I want to remove the duplicates in the ID, and combine them into one... While doing so, I want to keep the data as it is by creating dynamic columns reason_1, reason_2, reason_3 with their corresponding TIME. In case of same reasons, I want to add the TIME. The database is as follows:
ID     REASON     TIME
A     41A..........     27
A     93K..........16
B     89C...........3
B     93K...........7
B     48C..........     4
C     93K..........     24
C     93K..........     7
C     48C.........10
Expected Result is
ID     REASON_1......TIME_1.... REASON_2...TIME_2....REASON_3.........TIME_3
A........ 41A............ 27........... 93K............16
B........ 89C............ 3............ 93K............7...........48C.................. 4
C........ 93K........... 31.......... 48C..............10
Would be grateful if someone could try helping me out of this as early as possible.

You still haven't made it clear what the requirement is.
Is there a maximum number of reasons that can occur per ID? If so, you can code the pivoting of your data with something like:
SQL> ed
Wrote file afiedt.buf
1 with t as (select 'A' as ID, '41A' as reason, 27 as time from dual union all
2             select 'A', '93K', 16 from dual union all
3             select 'B', '89C', 3 from dual union all
4             select 'B', '93K', 7 from dual union all
5             select 'B', '48C', 4 from dual union all
6             select 'C', '93K', 24 from dual union all
7             select 'C', '93K', 7 from dual union all
8             select 'C', '48C', 10 from dual)

Also, as you're using 11g, you can use the new PIVOT query, for which you can find plenty of examples if you google or search these forums, or follow the FAQ link.
If you don't have any idea how many reasons there could be, then you really are looking at generating columns dynamically.
The problem with that is, because Oracle needs to know the SQL projection (see the FAQ link already provided), it has to know how many columns are going to be returned from a query before any data is fetched... but you are saying that the columns returned have to be based on the data itself. To do that you have two main options:
1) You query the data once to determine how many columns you are going to need and then dynamically build up a query in PL/SQL code with the right number of columns (or use one of the other dynamic methods shown in the FAQ)
or
2) You step back and ask yourself if SQL is really the best place to be trying to produce this output. Reporting tools are often better suited to this requirement as they are made to query the data back from a database and then pivot and layout the data based on the data returned.

Form with dynamic Column Names

Hello,
I am using "Form with report on table" and I would like to make use of dynamic column names labels that are derived from another table (sql). I am stuck on how to do this, any advice?

Try using this.
Select Col1, Col2, Col3

How to create a dynamic RTF report which creates dynamic columns based on dynamic column selection from a table?

Hi All,
Suppose I have table, whose structure changes frequently on daily basis.
For eg. desc my_table gives you following column name on Day 1
SQL > desc my_table;
Output
Name
Age
Phone
On Day 2, two more columns are added, viz, Address and Salary.
SQL > desc my_table;
Output
Name
Age
Phone
Address
Salary
Now I want to create an Dynnamic RTF report which would fetch data from ALL columns from my_table on daily basis. For that I have defined a concurrent program with XML as output type and have attached a data template/data definition to it which takes in XML as input and gives final output of conc program in EXCEL layout. I am able to do this for constant number of columns, but dont know how to do it when the number of columns to be displayed changes dynamically.
For Day 1 my XML file should be like this.
<?xml version="1.0" encoding="UTF-8"?>
<dataTemplate name="XYZ" description="iExpenses Report" Version="1.0">
<dataQuery>
<sqlStatement name="Q2">
<![CDATA[
SELECT Name
,Age
,Phone
FROM my_table
]]>
</sqlStatement>
</dataQuery>
<dataStructure>
<group name="G_my_table" source="Q2">
<element name="Name" value="Name" />
<element name="Age" value="Age" />
<element name="Phone" value="Phone" />
</group>
</dataStructure>
</dataTemplate>
And my Day 1, EXCEL output from RTF template should be like this.
Name Age Phone
Swapnill 23 12345
For Day 2 my XML file should be like this. With 2 new columns selected in SELECT clause.
<?xml version="1.0" encoding="UTF-8"?>
<dataTemplate name="XYZ" description="iExpenses Report" Version="1.0">
<dataQuery>
<sqlStatement name="Q2">
<![CDATA[
SELECT Name
,Age
,Phone
,Address
,Salary
FROM my_table
]]>
</sqlStatement>
</dataQuery>
<dataStructure>
<group name="G_my_table" source="Q2">
<element name="Name" value="Name" />
<element name="Age" value="Age" />
<element name="Phone" value="Phone" />
<element name="Address" value="Address" />
<element name="Salary" value="Salary" />
</group>
</dataStructure>
</dataTemplate>
And my Day 2, EXCEL output from RTF template should be like this.
Name Age Phone Address Salary
Swapnill 23 12345 Madrid 100000
Now, I dont know below things.
Make the XML dynamic as in on Day 1 there must be 3 columns in the SELECT statement and on Day 2, 5 columns. I want to create one dynamic XML which should not be required to be changed if new columns are added in my_table. I dont know how to create this query and also create their corresponding elements below.
Make the RTF template dyanamic as in Day1 there must 3 columns in EXCEL output and on Day 2, 5 columns. I want to create a Dynamic RTF template which would show all the columns selected in Dynamic XML.I dont know how the RTF will create new XML tags and how it will know where to place it in the report. Means, I can create RTF template on Day 1, by loading XML data for 3 columns and placing 3 XML tags in template. But how will it create and place tags for new columns on Day 2?
Hope, you got my requirement, its a challenging one. Please let me know how I can implement the required solution using RTF dynamically without any manual intervention.
Regards,
Swapnil K.

Hi All,
I am able to fulfil above requirement. Now I am stuck at below point. Need your help!
Is there any way to UPDATE the XML file attached to a Data Definition (XML Publisher > Data Definition) using a standard package or procedure call or may be an API from backend? I am creating an XML dynamically and I want to attach it to its Data Definition programmatically using SQL.
Please let me know if there is any oracle functionality to do this.
If not, please let me know the standard directories on application/database server where the XML files attached to Data Definitions are stored.
For eg, /$APPL_TOP/ar/1.0/sql or something.

Dynamic Column Names in Flat File Destination

Hello,
Inside a Data Flow Task, I have an ADO.Net data source which executes a stored procedure that provides results in 5 columns.
The requirement is to have it connect to a flat file destination, such that the column names is dependent on what data was pulled by the data source. There is a variable indicator which identifies the data that was pulled. For example:
If the indicator is 0, then the columns names will be A,B,C,D,E. Otherwise, if the indicator is 1, then column names will be V,W,X,Y,Z.
Any suggestions will be of great help.
AJ

If you only have two variations then use a branched execution (based on precedence constraints) and direct it to one DFT or another based on the result returned by the stored procedure.
Otherwise use .net
code to create one package or another dynamically.
PS: I suggest not to bother using SSIS for such a simplistic scenario.

Dynamic column names

I created a line chart with the following sql statement:
select null link, periode_jaar, sum(totaal) total from V_KPL_VZ_OWB@rapportage_dwhtest
where periode_jaar = (Select max(periode_jaar) from V_KPL_VZ_OWB@rapportage_dwhtest)
group by periode_jaar
order by periode_jaar
In the legend of the chart the line is named total. I would like have it named for example: Total 2009
So how i create the dynamic column? Any ideas? Tnx in advnaced

tnx for helping, i posted my xml code below where to put the tag: <format>{%Name} ({%Value})</format>

Dynamic Column name in a Cursor

Hello there,
How can I access data in cursor's field with dynamic fields names, more illustration follows:
My table has columns named as C1,C2,C3 so on
defined a cursor cursor_name on that table,
I need to access the fields by a loop like this:
OPEN cursor_name;
Fetch cursor_name into rec;
for i in 1 .. 10 loop
if rec.ci = 1Then
end if;
end loop
close cursor_name;
where rec,ci represents the name of the cursor fields, so that I loop over them,
how can I implement such an idea,
thanks in advance
regards

Thanks Bily, and user10715047,
actually the reason behind the need of such an approach, is as following:
assume that I have table of set of logical conditions, " LOGICAL CONDITIONS" has three columns: ID, Condition_name and the logical_condition, example:
1, c1, x = 1
5, c2, y = 2
10, c3, p = 3 where ID is just a sequence to identify the records from each other "primary key"
assume that I need to provide the possible combination of the result of applying each of the conditions, for example :
if c1 = 1 ,c2= 0 and c3= 1 then my result must be 1 ' This according some predefined rulesso that I created table which contains all the possible logical conditions, ( as the max number of logical conditions are known)
defined as follows : combination( combination_ID, c1, c2, c3, c4, ....cmax, result)
sample record:
combination_ID, c1, c2, c3, .. c max, result
100, 1, 0, 1, ....., 1, 1in the PL/SQL procedure, I would get all the needed combination, into a cursor, then to optimized the code, I need to access the fields ( which is the Ci) in a loop
for i in 1..3 loop
if cursor_rec.ci = 1 then
Action
end if;
end loop;the dynamic name I meant in my first post was this : cursor_rec.ci ,
so that I can access the cursor's fields without the need to name them one by one, as there could be long sequence of conditions to be checked.
hope that I made the idea clearer, Any suggestions, please !
anyway I will give the DBMS_SQL cursors a shot , try if I can use to implement the purpose,
as I know similar dynamical variable names, is available in Java,
Regards,

Dynamic Column Names using Refcursors

Hi,
I have a stored procedure which returns a refcursor. The refcursor contains a SQL query in which the column names and number of columns vary dynamically based on the date parameters passed.
"My objective is to return certain XYZ details of employees for a certain month range."
For ex: For the month of Aug-2011, the column names would be '1-AUG-11' to '31-AUG-11 and for Feb-2011 '1-FEB-11' to '28-FEB-11'
My issue is, when I execute the refcursor query using "EXEC", my column names/headings are preserved.
FIELD NAMES: EMPLOYEE_CODE XYZ_TYPE *1-AUG-11* *2-AUG-11* ... *31-AUG-11*
DATA: EMPCODE_Z TYPE1 VALUE_1 VALUE_1 ... VALUE_31
Whereas when I fetch the refcursor into a collection of nested table and display, my column names are lost.
DATA: EMPCODE_Z TYPE1 VALUE_1 VALUE_1 ... VALUE_31
Is there a way where I can preserve the column names from the refcursor after fetching into pl/sql collections?
Any help would be highly appreciated.
Thank you.

If not dynamic SQL, how can the number of columns be altered based on the input parameters?Cannot. A dynamic SQL projection means dynamic SQL (there's an exception to this, and despite interesting is not relevant to 99.99% of problems dealing with dynamic SQL projections).
You can however still use a dynamic projection and wrap that into a user defined type interface.
Here's the basic approach:
// create a user define type that will provide the wrapper for the SQL projection
create or replace type TString as table of varchar2(4000);
// build dynamic SQL projections via this type, e.g.
select
TStrings( object_id, object_name, created )
from user_objects
select
TStrings( emp_id, dept_id, salary, commission )
from employeesDespite the SQL cursors being different and the columns and number of columns being selected different, the SQL projection of both are the same. The Count method tells you the number of columns in the projection. Referencing an applicable column is simply done by using the column's sequential number in the projection.
You also do not have to use a collection or varchar2 as the wrapper type - you can create complex user objects and use the collection type for that, as the SQL projection.
Another alternative is converting the ref cursor into a DBMS_SQL cursor and using the latter's describe interface to dynamically determine the structure of the SQL projection and fetching the column values from it. But 11gr1 or later is needed for doing this.

My scenario is little different, let me explain:
My columns will remain same but values changes (based on column formula) according to the selected prompt value
If I select 'Oct' from prompt then
Curr will contain data for 'Oct' only
Next1 will contain data for 'Nov' only
Next2 will contain data for 'Dec' only
Next3 will contain data for 'Jan' of next year only.
Later if I select 'Jul' from prompt then
Curr will contain data for 'Jul' only
Next1 will contain data for 'Aug' only
Next2 will contain data for 'Sep' only
Next3 will contain data for 'Oct' only.
I don't have different columns for each months but the columns are capable to reflect data for any month.
So, how can I reflect the column name as month name for which that contains data.

Dynamic actions on button and dynamic column name

Hi!ynam
I want to create a dynamic action on button click in my tabular form.
I have a select list with values of my column names (P7_X_COLUMN) and a text field where users input values for update (P7_X_UVALUE).
My idea is that when they click the button, they update selected column to desired value in all rows.
However, I get the following error:
ORA-06550: line 5, column 5: PL/SQL: ORA-01747: invalid user.table.column, table.column, or column specification ORA-06550: line 4, column 1: PL/SQL: SQL Statement ignored (Go to error)
It seems to me that I have not referenced the column name correctly, I thought it was the same as referencing values. How do I do that?
This is my code:
begin
update "#OWNER#"."IZV_SLOG_DET"
set :P7_X_COLUMN=:P7_X_UVALUE;
end;

Ivan

I got it to work, but the query is too big. Can anyone help me with how to get it to work?

Dynamic column name with SELECT INTO

I am trying to build a function that derives a pay amount from a set of business rules. There are about 40 columns that hold various pay amounts and their column names are variations of 4 indicators (day shift, vs night shift, etc.) that I have to dynamically look up, ie here is the ID number and a timecard, now figure out which of the 40 fields to look up to get the pay amount.
I can determine from the timecard and employee ID which field to look at, but I'm getting hung up with the syntax needed to construct and execute the statement inside the PL/SQL block. I need to RETURN the pay I extract using the function, and I can create the correct SQL statement, but the EXECUTE IMMEDIATE won't accept the SELECT INTO syntax.
Can someone please suggest a solution? Here is the function:
create or replace FUNCTION FN_GET_PAYRATE(tc in NUMBER, e in NUMBER, pc in VARCHAR2)
RETURN NUMBER
IS
e_id NUMBER;
tc_id NUMBER;
pl_cd VARCHAR2(7);
shft VARCHAR2(2);
lvl VARCHAR2(2);
typ VARCHAR2(2);
e_typ VARCHAR2(4);
proj NUMBER;
hrly VARCHAR2(4);
payrt NUMBER;
var_col VARCHAR2(10);
sql_select VARCHAR2(200);
sql_from VARCHAR2(200);
sql_where VARCHAR2(200);
sql_and1 VARCHAR2(200);
sql_and2 VARCHAR2(200);
sql_and3 VARCHAR2(200);
sql_orderby VARCHAR2(200);
var_sql VARCHAR2(2000);
BEGIN
e_id := e;
tc_id := tc;
pl_cd := pc;
SELECT NVL(SHIFT,'D') INTO shft
FROM TS_TIMECARD_MAIN
WHERE TIMECARD_ID = tc_id;
--DBMS_OUTPUT.PUT_LINE('SHIFT= ' || shft);
SELECT NVL(PAY_LVL, 1), NVL(PAY_TYPE, 'B'), NVL(RTRIM(EMP_TYPE), 'LHD'), NVL(PROJECT, 001)
INTO lvl, typ, e_typ, proj
FROM TS_EMPLOYEES
WHERE EMP_ID = e_id;
--DBMS_OUTPUT.PUT_LINE('Level= ' || lvl);
--DBMS_OUTPUT.PUT_LINE('PAY_TYPE= ' || typ);
--DBMS_OUTPUT.PUT_LINE('EMP_TYPE= ' || e_typ);
--DBMS_OUTPUT.PUT_LINE('PROJECT= ' || proj);
IF e_typ <> 'LHD' THEN
hrly := 'H';
ELSE
hrly := '';
END IF;
IF proj <> 001 THEN
var_col := shft || lvl || typ || hrly;
--DBMS_OUTPUT.PUT_LINE('RATE COLUMN= ' || var_col);
sql_select := 'SELECT NVL(' || var_col || ', .01) INTO payrt';
sql_from := ' FROM TS_PAYRATES';
sql_where := ' WHERE PROJECT_ID = ' || proj;
sql_and1 := ' AND ACTIVE = 1';
sql_and2 := ' AND JOB_TYPE = ' || CHR(39) || e_typ || CHR(39);
sql_and3 := ' AND PILE_ID = ' || CHR(39) || pl_cd || CHR(39);
var_sql := sql_select || sql_from || sql_where || sql_and1 || sql_and2 || sql_and3 || sql_orderby;
DBMS_OUTPUT.PUT_LINE('SQL: ' || var_sql);
EXECUTE IMMEDIATE var_sql;
DBMS_OUTPUT.PUT_LINE('RATE= ' || payrt);
RETURN payrt;
ELSE
DBMS_OUTPUT.PUT_LINE('ERROR');
RETURN 1;
END IF;
END;
I have alternately tried this:
SELECT NVL(var_col,.01) into payrt
FROM TS_PAYRATES
WHERE PROJECT_ID = proj AND ACTIVE = 1
AND JOB_TYPE = CHR(39) || e_typ || CHR(39)
AND PILE_ID = CHR(39) || pl_cd || CHR(39);
as a substitute for the EXECUTE IMMEDIATE block, but I can't seem to use a dynamic substitution for the column name.
Any help would be greatly appreciated.

That's the most difficult part - the error messages seem to indicate a problem with the SQL statement in its execution context, because I can take the SQL string by itself and it executes perfectly.

Materialized view with dynamic column names !

hello,
i need some help , i'm trying ( i got no where so far :) ) to create a materialized
view that has dynamic field name values , so every time the view is refreshed
the fields are renamed.
i have been asked to create a decade summary view and to assign year values to field names,the years should be table columns ( not rows !? ) and thus i should reflect this fact to the column names.
i know its a wierd request but is there anway to do it ?
i dunno about it at least,
Thanks !

...or you could define the materialised view neutrally e.g. with columns like YEAR1, YEAR2 etc.
Then create a dynamically-defined view on top of this view, after it's refreshed, using the relevant years as column names. SELECT year1 AS "1991", year2 AS "1992" etc.
I still don't see how anybody is going to use these views as they won't know what the "year" columns are called.
And if the same materialised view is going to have different sets of data each time it's refreshed i.e. different sets of years, are you re-defining the selection criteria each time? If so, why not just define separate views?
It's a weird world out there...
