MYSQL Query with Session Variable

I would like to log in and after login success php will
automatically query records using my username as the parameter.
How can it be done in dreamweaver?
How can I insert multiple values dependent on what I selected
on a list/menu?
Thank you!

Query with bind variable, how can use it in managed bean ?

Hi
I create query with bind variable (BindControlTextValue), this query return description of value that i set in BindControlTextValue variable, how can i use this query in managed bean? I need to set this value in String parameter in managed bean.
Thanks

Put the query in a VO and execute it the usual way.
If you need to, you can write a parameterized method in VOImpl that executes the VO query with the parameter and then call that method from the UI (as a methodAction binding) either through the managed bean or via a direct button click on the page.

SQL query with Bind variable with slower execution plan

I have a 'normal' sql select-insert statement (not using bind variable) and it yields the following execution plan:-
Execution Plan
0 INSERT STATEMENT Optimizer=CHOOSE (Cost=7 Card=1 Bytes=148)
1 0 HASH JOIN (Cost=7 Card=1 Bytes=148)
2 1 TABLE ACCESS (BY INDEX ROWID) OF 'TABLEA' (Cost=4 Card=1 Bytes=100)
3 2 INDEX (RANGE SCAN) OF 'TABLEA_IDX_2' (NON-UNIQUE) (Cost=3 Card=1)
4 1 INDEX (FAST FULL SCAN) OF 'TABLEB_IDX_003' (NON-UNIQUE)

I have the same query but instead running using bind variable (I test it with both oracle form and SQL*plus), it takes considerably longer with a different execution plan:-

TABLEA has around 3million record while TABLEB has 300 records. Is there anyway I can improve the speed of the sql query with bind variable? I have DBA Access to the database
Regards
Ivan

Many thanks for your reply.
I have run the statistic already for the both tableA and tableB as well all the indexes associated with both table (using dbms_stats, I am on 9i db ) but not the indexed columns.
for table I use:-
begin
dbms_stats.gather_table_stats(ownname=> 'IVAN', tabname=> 'TABLEA', partname=> NULL);
end;
for index I use:-
begin
dbms_stats.gather_index_stats(ownname=> 'IVAN', indname=> 'TABLEB_IDX_003', partname=> NULL);
end;
Is it possible to show me a sample of how to collect statisc for INDEX columns stats?

From Clause query with form variables

forms 9.0.4 rdbms 9.2
Is it possible to create a From Clause query with form variables generated from another block (but in the same form)? I am not having any success.
I searched Metalink. It appears that according to DOC ID # 69884.1, in Forms 6i, this is not possible. Metalink suggest in DOC ID 104771.1 implementating a dynamic From Clause, but when I duplicate the example on my system, I receive an Oracle error. Further investigation from the web form (DISPLAY ERROR) indicates that the system does not see the dynamic value.
Has anyone else run into this error? Has this been fixed in forms 9.0.4 and I am just missing something? Does a dynamic from clause query work? Can anyone point me to an example or post an example or offer any advise.
thanks in advance

As far as I know it is not possible to use block items in a from clause query in forms 9.0.4. Here is my solution for a From-Clause-Query via the 'Query-Data-Source-Name-Property':
To use the values of the block items in my from clause query I implemented a database package with getter and setter routines for the block item values I needed for the query.
In the Key-Exeqry-Trigger of the From-Clause-Query-Block I set the global package variables with values of the block-items I am interested in. In the From-Clause-Query I used the values in the where-clause via package functions which return the global package variables.
Hope my solution will work for your problem.

Query with 2 variables

I have a query with two variables (Employee and Date). The query is working fine if both of the variables are check and values assigned. But if only one variable is checked and a value assigned then the query will return 0 results. Is it possible that the query cannot work with only one variable out of the 2? Do I need a workaround or am i doing something wrong?
Here is the query:
SELECT T0.DocNum, T0.DocDate, T0.DocDueDate, T0.CardCode, T0.CardName, T0.Address, T0.DocTotal, T0.U_Employee, T1.firstName,T1.lastName, T0.Comments FROM OVPM T0 LEFT JOIN OHEM T1 ON T0.U_EMPLOYEE = T1.FIRSTNAME' 'T1.LASTNAME WHERE T0.DocType = 'A' AND T0.U_EMPLOYEE = [%0] AND T0.DocDate =[%1].
Thank you so much for your help,
Irina Stanca

AFAIK, at least with 'complex queries' unchecked parameter gets
some default/blank value. Therefore, you should allow default values in your
WHERE clause.
You want: WHERE T0.COL = @VAR
You write: WHERE (T0.COL = @VAR OR [logical test for @VAR is a default value])
Snippets like this may help you in finding out that default value:
-- snip --
/SELECT FROM [dbo].[OHEM] T9/
declare @VAR_EMPL as char(20)
/* WHERE */
set @VAR_EMPL = /* T9.lastName */ '[%0]'
/SELECT FROM [dbo].[OVPM] T8/
declare @VAR_DATE as char(20)
/* WHERE */
set @VAR_DATE = /* T8.DocDate */ '[%1]'
SELECT '@VAR_EMPL: ' + '|' + @VAR_EMPL + '|' + '@VAR_DATE: ' + @VAR_DATE + ' DATEDIFF: ' + cast(DATEDIFF(day, CAST('1900-01-01' as datetime), CAST(@VAR_DATE as datetime)) as varchar)
[/code]
-- snip --
Yes, it looks like the default value for dates is '1900-01-01'.
Therefore, you may want to code this way
.. WHERE (DocDate = @VAR_DATE OR DATEDIFF(day, CAST('1900-01-01' as datetime), CAST(@VAR_DATE as datetime)) > 0)
I also noticed a date-related issue that may cause problems in complex queries
if you work with dates from last century AND if your date format in B1 is YY instead of CCYY:
you enter 1907 and B1 interprets it as 2007.

Issue with session variable

Hi,
I'm trying to setup a session variable to filter an Answer query based on the user login name. I've created the following
- A database table that contains a user name and its related filter (Entity)
- An initialization block for the session variable to issue the following sql: select Entity from table where user_name = ':USER'
- Created a target session variable called CURR_ENTITY as the target and assign a default value as 'No entity'.
- Filter my Answer query to use the session variable CURR_ENTITY
After restart of BI server and Presentation services and opening the report, CURR_ENTITY is always set to the default value. I've checked NQQuery,.log and looks like the initialization block was not returning any rows.
Any ideas on how to get around this issue? Thanks.
Regards,
Gerd

Hi gerd,
select Entity from table where user_name = ':USER'Check if this query is returning values in the backend DB.If so it is returning then it should work fine in session variable.
After defining the target variable CURR_ENTITY and test it in the screen.That shows you is it picking all the values or a single defaulted value.
If its showing all values then re-check your block once again.
(OR)
In the target variable instead of variable define row-wise initialization (i mean check it) and change the SQL in the variable to this
select 'CURR_ENTITY',Entity from table where user_name = ':USER'
and test it so you can use it in answers .....it should work with what is required.
hope answered the question.
Cheers,
KK

Filtering a Recordset with session variable

Hi
I am trying to filter a recordset based on a session
variable. The session variable is passed from the login page via a
username which is their email address. This has been successful.
However when I want to filter the users table - tbl_users to
show their first name it doesn't work.
I followed the adobe help tutorial plus ahave tried other
combinations and I am now at a loss on where exactly I am going
wrong.
The recordset is rs_UserAccess
I have a session variable called - MM_Username
The table has 5 records of various users
The code that I have fiddling with is -
<%
Dim rs_UserAccess
Dim rs_UserAccess_numRows
Set rs_UserAccess = Server.CreateObject("ADODB.Recordset")
rs_UserAccess.ActiveConnection = MM_conn_sidecounter_STRING
rs_UserAccess.Source = "SELECT * FROM tbl_users WHERE
username = MM_Username"
rs_UserAccess.CursorType = 0
rs_UserAccess.CursorLocation = 2
rs_UserAccess.LockType = 1
rs_UserAccess.Open()
rs_UserAccess_numRows = 0
%>
Any help would be appreciated. I have outlined below the
different combinations I have tested.
Try No1
rs_UserAccess.Source ="SELECT * FROM tbl_users WHERE username
= Session("MM_Username")”

Try this:

Keep that on one line.

Help with session variable please - CS5.5 PHP

Hi all,
I am needing a little assistance with using a session variable and hope that someone may point me in the right direction.
I have created a PHP page that uses the Dreamweaver 'User Authentication' feature, and the basics of this works fine, directing a user to the correct pages depending on whether they are or are not a valid user. I would like however to personalise the 'valid user' page with the persons Username as entered in the User Authentication table....a seemingly simple task using a session variable, but one that I just don't seem to be able to get working!
The code generated for the UA on page 1 is as follows:
<?php
// *** Validate request to login to this site.
if (!isset($_SESSION)) {
session_start();
$loginFormAction = $_SERVER['PHP_SELF'];
if (isset($_GET['accesscheck'])) {
$_SESSION['PrevUrl'] = $_GET['accesscheck'];
if (isset($_POST['txtfirst_name'])) {
$loginUsername=$_POST['txtfirst_name'];
$password=$_POST['txtsurname'];
$MM_fldUserAuthorization = "";
$MM_redirectLoginSuccess = "member_update.php";
$MM_redirectLoginFailed = "login.php";
$MM_redirecttoReferrer = false;
mysql_select_db($database_panto, $panto);
$LoginRS__query=sprintf("SELECT firstname, surname FROM web_access WHERE firstname=%s AND surname=%s",
    GetSQLValueString($loginUsername, "text"), GetSQLValueString($password, "text"));
$LoginRS = mysql_query($LoginRS__query, $panto) or die(mysql_error());
$loginFoundUser = mysql_num_rows($LoginRS);
if ($loginFoundUser) {
     $loginStrGroup = "";
    if (PHP_VERSION >= 5.1) {session_regenerate_id(true);} else {session_regenerate_id();}
    //declare two session variables and assign them
   $_SESSION['MM_Username'] = $loginUsername;
    $_SESSION['MM_UserGroup'] = $loginStrGroup;
    if (isset($_SESSION['PrevUrl']) && false) {
      $MM_redirectLoginSuccess = $_SESSION['PrevUrl'];
    header("Location: " . $MM_redirectLoginSuccess );
else {
    header("Location: ". $MM_redirectLoginFailed );
?>
Firstly, the text highlighted in red above appears to be setting the session variable that I require. Is This correct?
If so, what is the code that I need to place in page 2 to use that session variable? or
Do I need to do something else on page 1 to properly assign the session variable?
Would really appreciate your expertise
Mark

It looks as though you've set the columns incorrectly in the User Authentication server behavior. This is the SQL query that checks the user's credentials:
$LoginRS__query=sprintf("SELECT firstname, surname FROM web_access WHERE firstname=%s AND surname=%s",
    GetSQLValueString($loginUsername, "text"), GetSQLValueString($password, "text"));
You're looking for firstname and surname, whereas you should be looking for the user's login name and password.
$_SESSION['MM_Username'] is a session variable that stores the user's login name. To use it in a subsequent page, all that's needed is for the page to begin with session_start(). You can then echo the value to display it.
If you want to display the person's real name, you need to create a recordset in the second page using $_SESSION['MM_Username'] to find the firstname and surname. Alternatively, you can edit the existing code like this (I've copied only part of it):
$LoginRS__query=sprintf("SELECT firstname, surname FROM web_access WHERE firstname=%s AND password=%s",
    GetSQLValueString($loginUsername, "text"), GetSQLValueString($password, "text"));
$LoginRS = mysql_query($LoginRS__query, $panto) or die(mysql_error());
$loginFoundUser = mysql_num_rows($LoginRS);
if ($loginFoundUser) {
     $loginStrGroup = "";
    $row = mysql_fetch_assoc($LoginRS);
     $_SESSION['full_name'] = $row['firstname'] . ' ' . $row['surname'];
    if (PHP_VERSION >= 5.1) {session_regenerate_id(true);} else {session_regenerate_id();}
    //declare two session variables and assign them
   $_SESSION['MM_Username'] = $loginUsername;
    $_SESSION['MM_UserGroup'] = $loginStrGroup;
You can then use $_SESSION['full_name'] in a subsequent page that begins with session_start().

Problem with session variable

Hi,
After I insert a record into my MS Access database, it seems
to me that the session variable got destroyed so the next page
display the session variable as undefined. Has anyone have similar
problem? If so, how to work around that?
Thanks.
Tommy,

but its leading to jsp page error...For starters: never, never, ignore errors (exceptions and stacktraces). Those contain very, very, worthful information about the cause of the problem and what exactly went wrong. This way you can easily trackback the problem and solve it.
If you're unable to think logically and smart so that you can interpret the error yourself, if necessary with help of Google, then post it here. Then we'll tell you about the actual problem and possible soltions.
At any way:
iam displaying some data in a table using resultset object,now at the same time iam using to session variable to use the resultset object in my other applications...This already doesn't sound very good. You should never pass expensive resources around like that. You should acquire and close the Connection, (Prepared)Statement and ResultSet in the shortest possible scope. Preferably already in the same method as where you query the data.

Purchased ColdFusion 10: Having problem with session variables

My Dept. has just bought CF10 and I'm finally updating my existing web app to CF10 from CF8. My First Problem with CF10 is using session variables.
When using the lower version of CF (since CF 4 to 8) I have never had any problem setting up session variables and getting or using these variables in other pages after a successful login but with CF 10 it seems setting session variables and using them in other pages are a major problems. I'm not sure where have I done wrong in the codes.
First I'm setting the session in my Application.cfc This way:
<cfcomponent displayname="Application" output="true">
<cfset THIS.Name ="MyNewApp"/>
<cfset THIS.ApplicationTimeout = CreateTimeSpan(0,0,20,0) />
<cfset THIS.SessionManagement ="YES"/>
<cfset THIS.SessionTimeout = CreateTimeSpan( 0, 0, 20, 0 ) />
<cfset THIS.SetClientCookies = false />
<cffunction name="OnApplicationStart" access="public" returntype="boolean" output="false">
<cfset application.Main_DSN = "TESTDB">
<cfreturn true />
</cffunction>
<cffunction name="onApplicationEnd" output="false">
      <cfargument name="applicationScope" required="true">
    </cffunction>
<cffunction name="OnSessionStart" access="public" returntype="void" output="false" hint="Fires when user session initializes.">
<cfset session.loggedin = "NO">
<cfset session.username = "">
<cfset session.userrights = "">
<cfset session.usergroup = "">
</cffunction>
</cfcomponent>
After login, user is validated and set values to those session.variables:
........user validation codes here......................
<cfif mylogin NEQ true>
      <cflocation url="/login/login.cfm">
      <cfabort
<cfelse>
      <cfset session.loggedin="Yes">
      <cfset session.username="#Trim(Form.username)#">
     <CFSET qUserRights = LoginObj.getUserRights('#Trim(Form.username)#')>
     <cfset session.userrights = qUserRights>
    <CFSET qUserGroup = LoginObj.getUserGroup('#Trim(Form.username)#')>
        <cfloop query="qUserGroup">
           <cfset session.usergroup = user_group>
           <cfbreak>
        </cfloop>
    
   <cfdump var="#session.loggedin#">
   <cfdump var="#session.username#">
   <cfdump var="#session.userright#">
   <cfdump var="#session.usergroup#">
</cfif>
In index.cfm, Before Login I got:
session.loggedin = NO
session.username = ["empty string"]
session.userrights = ["empty string"]
session.usergroup = ["empty string"]
After a successful Login:
session.loggedin = NO
session.username = ["empty string"]
session.userrights = ["empty string"]
session.usergroup = ["empty string"]
Have I done something wrong? These codes work on CF8. Please help.
I need to mentioned:
CF10 is in Linux and my web app is under https not http. But these session variables should be shared bentween http and https because some older application are still in http.

On which page is the following code?
After login, user is validated and set values to those session.variables:
........user validation codes here......................
<cfif mylogin NEQ true>
      <cflocation url="/login/login.cfm">
      <cfabort
<cfelse>
      <cfset session.loggedin="Yes">

    <CFSET qUserGroup = LoginObj.getUserGroup('#Trim(Form.username)#')>

Create collection from query with bind variable

Apex 4.0.2
Per Joel Re: Collection with bind variable the apex_collection.create_collection_from_query_b supports queries containing bind variable references (:P1_X) but I am not sure how to use this feature, the documentation doesn't have an example, just the API signature for the overloaded version has changed.

Report query with bind variable

Trying to create a report query for xsl-fo print. For output format I pick "derive from item" then pick the item name from the list, on the next screen, I paste the query with the bind variable. on the next step test query, I always get "data not found" regardless what value I type in. This is the same query that I ran under sql commands without any issues.
Does anyone run into the same issue as I have when attempted to create a query with bind var ? There is no problem creating a query without bind varibles. . thanks.

Hi, please did you get any solution to this issue? I am having similar challenge right now.
select     EMP.DEPTNO as DEPTNO,
     DEPT.DNAME as DNAME,
     EMP.EMPNO as EMPNO,
     EMP.ENAME as ENAME,
     EMP.JOB as JOB,
     EMP.MGR as MGR,
     EMP.HIREDATE as HIREDATE,
     EMP.SAL as SAL
from     SCOTT.DEPT DEPT,
     SCOTT.EMP EMP
where EMP.DEPTNO=DEPT.DEPTNO
and      DEPT.DNAME =upper(:dname)
This run perfectly in sql developer, toad, and even inside publisher if I login directly to publisher to create report.
Generating this same query in shared component query builder and testing it returns no data found. If I remove the last line, it works. but with the last line, it return no data found. It seems no one has been able to provide solution to this issue

Issue with SQL Query with Presentation Variable as Data Source in BI Publisher

Hello All
I have an issue with creating BIP report based on OBIEE reports which is done using direct SQL. There is this one report in OBIEE dashboard, which is written using direct SQL. To create the pixel perfect version of this report, I am creating BIP data model using SQL Query as data source. The physical query that is used to create OBIEE report has several presentation variables in its where clause.
select TILE4,max(APPTS), 'Top Count' from
SELECT c5 as division,nvl(DECODE (C2,0,0,(c1/c2)*100),0) AS APPTS,NTILE (4) OVER ( ORDER BY nvl(DECODE (C2,0,0,(c1/c2)*100),0)) AS TILE4,
c4 as dept,c6 as month FROM
select sum(case when T6736.TYPE = 'ATM' then T7608.COUNT end ) as c1,
     sum(case when T6736.TYPE in ('Call Center', 'LSM') then T7608.CONFIRMED_COUNT end ) as c2,
     T802.NAME_LEVEL_6 as c3,
     T802.NAME_LEVEL_1 as c4,
     T6172.CALENDARMONTHNAMEANDYEAR as c5,
     T6172.CALENDARMONTHNUMBERINYEAR as c6,
     T802.DEPT_CODE as c7
from
     DW_date_DIM T6736 /* z_dim_date */ ,
     DW_MONTH_DIM T6172 /* z_dim_month */ ,
     DW_GEOS_DIM T802 /* z_dim_dept_geo_hierarchy */ ,
     DW_Count_MONTH_AGG T7608 /* z_fact_Count_month_agg */
where ( T802.DEpt_CODE = T7608.DEPT_CODE and T802.NAME_LEVEL_1 = '@{PV_D}{RSD}'
and T802.CALENDARMONTHNAMEANDYEAR = 'July 2013'
and T6172.MONTH_KEY = T7608.MONTH_KEY and T6736.DATE_KEY = T7608.DATE_KEY
and (T6172.CALENDARMONTHNUMBERINYEAR between substr('@{Month_Start}',0,6) and substr('@{Month_END}',8,13))
and (T6736.TYPE in ('Call Center', 'LSM')) )
group by T802.DEPT_CODE, T802.NAME_LEVEL_6, T802.NAME_LEVEL_1, T6172.CALENDARMONTHNAMEANDYEAR, T6172.CALENDARMONTHNUMBERINYEAR
order by c4, c3, c6, c7, c5
))where tile4=3 group by tile4
When I try to view data after creating the data set, I get the following error:
Failed to load XML
XML Parsing Error: mismatched tag. Expected: . Location: http://172.20.17.142:9704/xmlpserver/servlet/xdo Line Number 2, Column 580:
Now when I remove those Presention variables (@{PV1}, @{PV2}) in the query with some hard coded values, it is working fine.
So I know it is the PV that's causing this error.
How can I work around it?
There is no way to create equivalent report without using the direct sql..
Thanks in advance

I have found a solution to this problem after some more investigation. PowerQuery does not support to use SQL statement as source for Teradata (possibly same for other sources as well). This is "by design" according to Microsoft. Hence the problem
is not because different PowerQuery versions as mentioned above. When designing the query in PowerQuery in Excel make sure to use the interface/navigation to create the query/select tables and NOT a SQL statement. The SQL statement as source works fine on
a client machine but not when scheduling it in Power BI in the cloud. I would like to see that the functionality within PowerQuery and Excel should be the same as in Power BI in the cloud. And at least when there is a difference it would be nice with documentation
or more descriptive errors.

Row level security with session variables, not a best practice?

Hello,
We are about to implement row level security in our BI project using OBIEE, and the solution we found most convenient for our requirement was to use session variables with initalization blocks.
The problem is that this method is listed as a "non best practice" in the Oracle documentation.
Alternative Security Administration Options - 11g Release 1 (11.1.1)
(This appendix describes alternative security administration options included for backward compatibility with upgraded systems and are not considered a best practice.)
Managing Session Variables
System session variables obtain their values from initialization blocks and are used to authenticate Oracle Business Intelligence users against external sources such as LDAP servers or database tables. Every active BI Server session generates session variables and initializes them. Each session variable instance can be initialized to a different value. For more information about how session variable and initialization blocks are used by Oracle Business Intelligence, see "Using Variables in the Oracle BI Repository" in Oracle Fusion Middleware Metadata Repository Builder's Guide for Oracle Business Intelligence Enterprise Edition.
How confusing... what is the best practice then?
Thank you for your help.
Joao Moreira

authenticating / authorizing part is take care by weblogic and then USER variable initialized and you may use it for any initblocks for security.
Init block for authenticating / authorizing and session variables are different, i guess you are mixing both.

Problem with Session variable initialization block

Hi,
I'm getting strange results when using session variables in my repository files.
I have created session variables as specified in the document which is available at
http://www.oracle.com/technology/obe/obe_bi/bi_ee_1013/bi_admin/biadmin.html
The main problem getting with the system session variable (USER) in the select statement.
My select statement is as follows,
select ':USER',case when upper(':USER') = 'KUMAR' then 'APR-05' end from Dual
The problem is while logging into the BI Answers it is allowing all the invalid users to login who does not exist.
when i remove the quotes and simply use :USER in the select statement it is not allowing the invalid users to login but giving error while displaying the results.
when i remove the user variable from select statement its giving correct results.
Can i know what is causing the problem.
Thanks,
Kumar.
