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.

Bind Variable in SELECT statement and get the value in PL/SQL block

Hi All,
I would like pass bind variable in SELECT statement and get the value of the column in Dynamic SQL
Please seee below
I want to get the below value
Expected result:

Thanks Billy, Would you be able to suggest any other faster method to load the data into table. Thanks,
As Mark responded - it all depends on the actual data to load, structure and source/origin. On my busiest database, I am loading on average 30,000 rows every second from data in external files.
However, the data structures are just that - structured. Logical.
Having a data structure with 100's of fields (columns in a SQL table), raise all kinds of questions about how sane that structure is, and what impact it will have on a physical data model implementation.
There is a gross misunderstanding by many when it comes to performance and scalability. The prime factor that determines performance is not how well you code, what tools/language you use, the h/w your c ode runs on, or anything like that. The prime factor that determines perform is the design of the data model - as it determines the complexity/ease to use the data model, and the amount of I/O (the slowest of all db operations) needed to effectively use the data model.

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
santosh

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.

But if you will use double '&&' the value of m1 will be persistent across the session..

JDBC Sender MSSQL Stored Procedure - Multiple Select Statements

Hello all,
I will proceed to tell you my problem, for which solution I request your kind advice:
Im working in a project for a retailer, which consists in sending the information from erp and sql server to pos thru XI interfaces.
One of the interfaces is about sending items from sql server to a file so the pos can load it into the system. For doing so I have devloped an stored procedure which function is to return several select statements as many stores the retailer might have, so they can have a different file per store along with its corresponding items in it.
The thing is that XI just gets the first select statement and creates the corresponding file, but it seems to ignore the remaining responses as I'm neither getting any file nor an error afterwards.
So, my question is: is XI capable of handling multiple select responses from an Stored Procedure in graphical mapping??? Or am I just wasting my time trying?
Thanks in advice for your help.
Regards.

Hello Ramkumar,
After 5 days trying, I finally made it work out applying your advice. Below the short explanation of what I did:
My Source structure is: Main Node->Row->Records (Material Number, StoreNum, Price, Status)
My Target structure is: Main Node->File Node->Record Node->Records ( Material Number, Price, Status)
The key was to make all the occurrences happen against StoreNum node. So, based on what you adviced these two where the key mappings:
1) The Mapping that will create a new file for each different store that comes in the query (In my case, query was already sort by store using an sql "order by" function, if not you can also use xi node function "sort" as Ramkumar suggested)
StoreNum->RemoveContext->SplitbyValue (Value Changed)->Collapse Contexts->File Node
2) The Mapping that will create each record in its corresponding store file:
StoreNum->RemoveContext->SplitbyValue (Value Changed)->Record Node
And Voilá !!! It worked.
Thanks very much Ramkumar.
Regards.

Variable in Select statement JDBC sender

Hi All,
I am working on JDBC sender and this scenario is working fine. Now the legacy system has different enviroment for development, quality and production so I need to change the enviroment for each system.
Is there any way I can make it as variable and the movment it system checks it's development of XI system then it should pick up right enviroment for legacy system and that can be used in select statement.
My select statement looks like and highlighted one is the enviroment which needs to be a variable.
select digits(HMOUTLT) as HMOUTLT, hmprodu as HMPRODU, HMCHKOQ as HMCHKOQ, HMCHKiQ as HMCHKIQ, HMWKPER as HMKPER, HMLSDAT as HMLSDAT from bi5filmm.bsimhp where hmprflg = ' ' and rrn(bsimhp) < 3000 and hmextdt = '2007-12-24'.
I am not sure if value mapping can be used here or not.

Using variable in select statement (php)

I am having difficulty using a variable in a select
statement.
The following manual query (using a static date) works fine:
$query_Recordset1 = "SELECT * FROM academyClasses WHERE
classDate > '2006-06-01' ";
However, If I use the following:
$dateVar = date('Y-m-d');
mysql_select_db($database_mw, $mw);
$query_Recordset1 = "SELECT * FROM academyClasses WHERE
classDate > $dateVar ";
ALL records are returned, which means the $dateVar variable
is not being recognized. I have compared the $dateVar values
<?php echo $datetime; ?> against the actual value of my date
field <?php echo $row_Recordset1['classDate']; ?> in my
results table and it seems that the values are indeed accurate in
terms of a date 2006-06-04 for example.
My date field "classDate" is of a "date" type within the
mysql database. I'm using Dreamweaver MX 2004 with Mac OSX 10.3.9.
I'm sure this is just a syntax problem, at least I hope it
is.
Any help is greatly appreciated.

Try this:

print $query_Recordset1;
See what is in the SQL statement.

Passing a variable to select statement

Hi there,
I have a selection screen on which you can choose which table do you want to display.
I store the name of the selected table in a variable tab_name.
I want to use something like that:
data: tab_name(40).
select * from tab_name
    into gt_master.
endselect.
But it did not allowed because tab_name is not a database table.
Is it possible to pass the table name in a select statement using a variable?

Hello
Yes it is posible you can use a dynamic select...
Try this:
DATA tabname(10).
DATA: BEGIN OF wa,
        id   TYPE scustom-id,
        name TYPE scustom-name,
      END OF wa.
tabname = 'SCUSTOM'.
SELECT id name INTO CORRESPONDING FIELDS OF wa FROM (tabname).
WRITE: / wa-id, wa-name.
ENDSELECT.
or
CONSTANTS: flight_tab_name(30) VALUE 'SPFLI'.
DATA: from_clause TYPE STRING.
DATA: BEGIN OF wa,
        name(20) TYPE C,
        connid   TYPE spfli-connid,
      END OF wa.
CONCATENATE flight_tab_name ' AS t1'
            ' JOIN scarr AS t2 ON t1carrid = t2carrid'
   INTO from_clause.
SELECT t1connid t2carrname AS name
    FROM (from_clause)
    INTO CORRESPONDING FIELDS OF wa.
WRITE: / wa-name, wa-connid.
ENDSELECT
Hope this helps

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)??

Hi All
Am I loosing the plot .. but we have a select statement run from discoverer which is causing the famous snapshot too old 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

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.
/76...

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'
