Dynamic rowsize from select statement.

Hi, I'm trying to get the lenght if the returned row from a select statement but I'm not sure how to do this properly.
The statement contains 530 columns of different type, mostly VARCHAR but also different number formats and timestamps.
I've tried to use LENGTH() + LENGTH() but our interactive SQL client is not very happy with the enormous statement size.
Thank you in advance.

I think you need something like this:
select column_name "name", data_type "type",
data_length "length", nullable "null"
from all_tab_columns
where table_name =' Your table_name'

Dynamic field in Select Statement

I am able to create a dynamic statement to insert into the where clause of my sql, but I am unable to dynamically create a select statement. Oracle Reports produces the following error:
REP-0499: Column " selected by the query is incompatible with report definition.
Here is an example of my select:
Select

Any help is appreciated.

I figured it out. Thanks

How to find the number of fetched lines from select statement

Hi Experts,
Can you tell me how to find the number of fetched lines from select statements..
and one more thing is can you tell me how to check the written select statement or written statement is correct or not????
Thanks in advance

Hi,
Look for the system field SY_TABIX. That will contain the number of records which have been put into an internal table through a select statement.
For ex:
data: itab type mara occurs 0 with header line.
Select * from mara into table itab.
Write: Sy-tabix.
This will give you the number of entries that has been selected.
I am not sure what you mean by the second question. If you can let me know what you need then we might have a solution.
Hope this helps,

How to pass rowtype argument to a function from select statement?

Hi all!
I have function that takes mytable%rowtype as in parameter. can I pass entire row of mytable to the function from select statement? kind of
select myfunction(mytable.*) from mytable where ....
Thanks in advance

The function can be used in a SQL statement only if it accepts SQL types and returns SQL type. %ROWTYPE being PL/SQL construct and not a SQL datatype, can not be used in this context.

Dynamic sql for select statement

Hi,
Please help me with the below code:
It is updating null if the select statment returns one values. If it fetches multiple values then it throughs the below error msg when running the program.
Please let me know how to modify the below code. Or let me know is there anyother way to write this code.
Logic for development:
* View name should be passed as dynamic.
CREATE OR REPLACE
PROCEDURE "PKEP_LOAD_SO_EU" (p_var1 IN VARCHAR2)
IS
lv_sql VARCHAR2 (4000);
lv_name VARCHAR2 (20);

FROM BIIO_SALES_OB_IMPORT_'|| p_var1;
EXECUTE IMMEDIATE lv_sql
INTO lv_name;
BEGIN
UPDATE BIIO_SALES_OB_IMPORT_NA2 --table name for updation
SET SOB_1 = NULL,

COMMIT;
EXCEPTION
WHEN OTHERS

Dynamic Parameter LOV Select Statement

I have a parameter form with a value for the fiscal year and equipment ID. I want to populate the equipment ID list of values based on the fiscal year that is selected.
My query for the equipment ID list of values would be SELECT EQPID,NAME FROM EQPLIST WHERE FY = :FY.
When I tried to add this query to the list of values of the equipment ID parameter I get REP-0781: Bind variables are not allowed in the Select statement.
Is there a way to dynamically generate the list of values select statement in a reports trigger?

Hi,
What version of Oracle Reports are you using?
Unfortunately, it is a limitation of Oracle Reports to not restrict values based on other parameters - for sure until Reports 6i and I believe until the recent new versions.
The other way to do what you want to do is to do it outside of Reports, if you have an Oracle Forms application. For example, you can create a simple Oracle Form that captures the Report parameters and then submits the report from the Forms. In Forms, you can implement the solution you are looking for - restricting values based on values of other parameters. In reports, you can't do that.
If you have a few other reports that have similar requirements, then you can create a form to launch reports and submit all your reports from there after capturing all your parameters there.

Dynamic fields in select statement

Hi all,
   In selection screen we are having period as select option.The values for period are 01 to 16. Based on
      the values entered in selection screen for period we need to select HSLXX from FAGLFLEXT.
   For example if we enter 01 to 03 in selection screen then we need to select HSL01 HSL02 HSL03
       from FAGLFLEXT.
Like this we need to select fields dynamically in select statement. Can any one tell me how to restrict fields dynamically.

append where_clause to where_tab.

Storing variable from select statement

I need to store a variable from a select statement into a session. Before I was taken what was passed from another page and throwing it into a session.--
String Password= request.getParameter("Password");
String sql = "Select WEB_USER_ID FROM Web_User WHERE PASSWORD = '" + Password +"'";
session.setAttribute("USER",Password);
Now though I need to put in Web_User_Id and cannot find the proper syntax. Can someone help
session.setAttribute("User",???????);

WEB_USER_ID is unidentified because it is a column name, not a variable name. You should first assign its value to a variable and then put the variable name into the setAttribute statement instead.
Your query may return more than one result based on the way it is written. It sounds like you are trying to find all users with a password that is equal to the value of Password. If this is correct, then are you trying to create an attribute for each user?
If your intention is to locate a user, then the user id and password should have been provided. A variable should be defined for both the password and user id. You should then add the user id to the where clause. After a successful search, the attributes can be created using the same syntax.

Dynamic table in select statement

Hi All,
I have a requirement where i have a select option in which the input is table name , i need to use this input in my select statement and fetch entries in the table where bname is eq to ' ' or uname eq ' '.
the challenge that i am facing is not all the tables have both the fields (uname and Bname).
Request your help on how to code the above requirements.
Thanks,
Bhanu.

Bhanu,
I don't know what exactly is your requirement but I don't see any reason why a business user enters a table name as input in the selection screen.
MANDT NAME                           TYPE NUMB SIGN OPTI   LOW    HIGH
223   ZPROGNAME                       P    0001     I        EQ    XXX      ZTABLENAME
You can maintain an entry like the above in TVARVC table and get the table name using a select query on TVARVC and then use the table as below
SELECT SINGLE * FROM (l_tabname)
           into g_wa_tab2
           WHERE quosrc   EQ g_wa_tab1-quosrc AND
                 quotyp   EQ g_wa_tab1-quotyp AND
                 quotno   EQ g_wa_tab1-quotno AND
                 quotdate EQ g_wa_tab1-quotdate.
Funda is using TAVRVC to maintain the table names and determine the table based on a condition and the using the table in the select query.
Thanks,
K.Kiran.

Calling PL/SQL code from Select statement

Hi
I have a PL/SQL function to calculate a value.
create or replace procedure "SR_GROSS_MARGIN"
(netsales IN NUMBER,
margin IN NUMBER,
GM OUT NUMBER)
is
BEGIN
    IF NETSALES = 0 THEN
       GM := 0;
    ELSIF
       NETSALES < 0 THEN
       GM := 0;
    ELSE
       GM := NETSALES / MARGIN;
    END IF;
END;How do I call this from a SELECT statement?
Regards
Adam

here you go:
create or replace function SR_GROSS_MARGIN
(netsales IN NUMBER,
margin IN NUMBER)
return number
is
gm number;
BEGIN
    IF NETSALES = 0 THEN
       GM := 0;
    ELSIF
       NETSALES < 0 THEN
       GM := 0;
    ELSE
       GM := NETSALES / MARGIN;
    END IF;
return gm;
END;then you can:
select gm(2500,20) from dual;

Snapshot too old ORA-01555 from select statement (discoverer)??

Am I loosing the plot .. but we have a select statement run from discoverer which is causing the famous snapshot too old error.
My understanding is that undo is generated from select/insert/update.
So why is the following discoverer Select statement causing the error?

The SELECT statement is the victim.
Some session is doing DML against the same table against which the SELECT occurs & is likely doing COMMIT inside a LOOP.

Passing values to OnDemandProcess from Select Statement on Reports Page

I think I'm just missing some of the proper syntax, Can somebody please help me.
As I've come to understand this process of passing the values,
I recognize it as (3) steps.
1. Referencing the "javascript" in the Select Statement of the Reports Page.
2. Including the "javascript" in the Page Header region.
3. Defining the Process as an OnDemand Application Process.
My problem is:
a. I can't seem to get the Value passed to the Application Process.
b. I don't know how to reference the Value passed once I get it passed.
Here's what I've got done so far:
1. (The Select Statement)
   onClick="javascript:ORDER_CONNECT_SEQUENCE('||ID||')
{code}
2. (The javascript)
{code}
function ORDER_CONNECT_SEQUENCE('+ID+')
var get = new htmldb_Get(null,$x('pFlowId').value,'APPLICATION_PROCESS=ORDER_CONNECT_SEQUENCE',0);
get.add('+ID+');
gReturn = get.get('+ID+');
{code}
3. (The Application Process)
{code}
   BEGIN
   Select '+ID+' into THIS_CIRCUIT from dual;
{code}
I Know that the Application Process is being referenced and that the OnClick routine is working properly,
because if I plug a Value into the Application Process, instead of using '+ID+',
Then I get all of my desired results.
Any help you can give me here is greatly appreciated.
Thanks- Gary

Dimitri, Thanks for your efforts here, but its still not working for me.
Here's what I understand from your suggestions:
1. (changes to the javascipt)
   a. replace function ORDER_CONNECT_SEQUENCE('+ID+')
       with
       function ORDER_CONNECT_SEQUENCE(pId)
   b. replace get.add('+ID+')
       with
       get.addParam('x01',pId)
   c. replace getReturn = get.get('+ID+')
      with
      getReturn = get.get()
      get = null2. (chages to the Application Process)
   a. add l_value varchar2(4000) to my list of declarations
   b. add l_value := wwv_flow.g_x01 below the begin statement
   c. I guess then I would reference the l_value like this:
       Select l_value into THIS_CIRCUIT from dual* Also, You didn't mention any changes in my Select statement in the Reports region of the page.
FYI.
onClick="javascript:ORDER_CONNECT_SEQUENCE('||ID||')
{code}
The 'ID' which I'm referencing here is an ID from the table which I'm querying.
Am I misunderstanding you somewhere?
Thanks- gary

View last 5 lines from select statement?

Hi,
I would like to view only the last 5 lines from a select statement, how would this be done?
Something like:
select * from a .................
regards
RobH

Hi RobH,
First of all: You need to identify a criterion that helps to sort your data in the desired way.
Done that you can start to read about analytical functions, maybe ROW_NUMBER(), RANK() and / or DENSE_RANK() might be interesting.
Edit:
Changed rn() to row_number()
