I want to use the SQL query IF EXIST to update or insert data in a ms access table, but it doesn´t work

Hi,
I want to use the SQL query IF EXIST to update or insert data in a ms access table, but it doesn´t work
(fault number -2147217900)
I want to search for a value in a ms access table , if it exist i want to update it, if not i want to insert a new row.
Working with LabView 7.1, database con. toolset.
Who can HELP?
Thanks a lot
Marco

Hello,
I think that If exist is not a standar SQL command (I know it exists I think in Oracle and SQL server), MS access doesn't support it, so I think the best way to do it is first make a Select and then either an Update or an insert, sorry...

Lightswitch html use the 'any' query method

Hi
Can someone please tell me how i can use the "any" query method for entity collections in lightswitch html?
Thanks

Hi Xpert360
It's for a type of EntityCollection this is the code from the msls-2.5.2.vsdoc.js line 2220
any: function any(predicate) {
/// <summary>
/// Determines whether this sequence contains any
/// items that optionally satisfy a condition.
/// </summary>
/// <param name="predicate" type="Function" optional="true">
/// A function to test each item for a condition.
/// <br/>Signature: Boolean item.predicate(item)
/// </param>
/// <returns type="Boolean">
/// True if this sequence contains any items that
/// satisfy the condition, if any; otherwise, false.
/// </returns>
var result = false;
this.each(function (item) {
if (!predicate || predicate.call(item, item)) {
result = true;
return false;
return true;
return result;
Check it out and let me know if you know how to use it, my problem is how to use the call back function.
Thanks

Not getting 'actual data' in the planning query

Hi all,
I am debug other's query. This cube stores 'actual' and 'plan' data and I loaded 'actual' and can see it in the cube. But I cannot see 'actual data' when I run the planning query.
I checked all restrictions in the KFs and CHARs and fliters in the query. There are only 'value type 10', 'fiscal year variant Z1', and 'currency CAD' restricted and actual data does contain those values in all line items.
Can someone point it out what it could be the issue? Thank you.
R.

Hi,
if you enter some data (plan data) you cannot see it again. Is that correct?
are you using the same query to enter and to see plan data?
Because if you are entering data in an aggregate level and you are executing your query over the infocube you will not see the data from the yellow request. If you execute query over the aggregate you should be able to see all data in the cube (yellow and green requests).
Also check if your query is defined as per note 1136163.
I hope this helps.

Creating multiple tab reports using the same query in Web intelligence

Hi All,
I have created a Universe on a BW Query which has fields as below
AGE Depaatment Gender Grade
25       FIN                M            A
27       LES               F            A+
60       SWS            M             A++
Based on this data i have created a WEbi report which shows all of these data under one tab.
Now i create a new report tab in the same Webi Document by right cliicking the existing report and going to inset report and saving it.
Similarly i create two more new report tabs.
in each of these tabs i want to show data only for the concened departments.ie =1st report contains all the departments.
2nd report contains only finance data, third contains only Les data and fourth only SWs Data.
Is it possible to create this report using the same query?
Regards,
Raj.

You should use report filters, not query filters.
A query filter will affect the entire document. Every report tab that pulls data from that query will be impacted. If you start with a single report, by default it shows the data from the query. If you duplicate that report tab, then it's still attached to the first query. There are various ways to create report filters (input controls, quick filter, invoking the filter area from the toolbar) and a report filter impacts only blocks on that report tab. You can even create block filters by clicking on the block first, then creating your filter.
This is a fairly confusing bit for folks that are new to Web Intelligence.

How use the method hasPermission in weblogic server 6.1

Hello everybody !
In my application web ,i restrict access to some ressources (some jsp)
to some specified groups .
So,i create permissions in the file web.xml , as indicated in the doc
6.0 .
For example only the user : system can access to all the jsp , and the
others users no .
Now ,in my code ,I would like to use the method hasPermission in order
to modify my application according to the differents groups of users .
But my problem is that i don't know the parameter aclName !
For the parameter permission I use the syntax "new
weblogic.security.acl.PermissionImpl(".../x.jsp") .
For the parameter sep (char),i use : '.' .
But i don't find the parameter aclName .
When i was in weblogic 5.1 ,i created permission in the file
weblogicURL.policy with the syntax : " Permission
weblogic.security.acl.URLAcl "weblogic.url",".../x.jsp" " and after
i gave "weblogic.url" as parameter for aclName .
But in version 6.0, I try web.xml, web ? but nothing is good .
Is there any person which have an idea or the solution ?
All the sugestions are welcome !
Thanks by advance !
Good bye .

hi,
maybe a better approach could be to use roles instead of permissons.
Your menu.jsp could look like this:
<%
if(request.isUserInRole("super-user"))
%>
... code HTML where the button "Creation" is created
<%
%>
You can map the role 'super-user' to an individual principal or a
user group in weblogic.xml. In that case only users that are in
the mapped group/principal will see the 'creation' link. So simply
add user 'system' to a group 'super-user'.

Hi Kirann and everybody!
Thanks for your message .
I'm going to explain better than the first time .
I set up security-constraints in my web.xml .
For example only "system" can access to the directory Creation and
all its .jsp , and the others users no .
Now ,in my code , there is a jsp : menu.jsp which displays some
possibilities : creation of an employee , visualisation ...with HTML
code : button "Creation" which call a .jsp of the directory Creation .
Actually , if a user different of "system" try to click on the button
"Creation" there is a dialog box of login . The user writes its loggin
but the access is prohibited ( because security-constraint in web.xml
).It's normal but not very well .I would like that a user who don't
have access to the functionality "Creation" don't see the button
"Creation" !
So in menu.jsp , i would like to use the method hasPermission at the
location of the button "Creation" is created with HTML code :
<%
if weblogic.security.acl.Security.hasPermission(.....,new
weblogic.security.acl.PermissionImpl("/Creation/x.jsp"),'.')
%>
code HTML where the button "Creation" is created
<%
%>
But my problem is that i don't know the first parameter which
correspond
to aclName .
Any suggestions are welcome .
Thanks for help .

How to use the method getParameterValues() of request object in JSP?

I'm trying to use the method
String a[]=request.getParameterValues("ch_box");
to retrieve the values from the form
but it gives the error
"Method getParamaterValues(java.lang.String) not found in interface javax.servlet.http.HttpServletRequest."
so plz tell me how to overcome this hurdle?
thanx

Well, just one note... either you have a typo in your code, or else in your post.
If you cut and pasted the error message (which it looks like you did), then the method getParamaterValues() should be getParameterValues() instead (notice the spelling difference), so you probably just have a typo in your code.

Problem in finding Exact result by using the following Query

Hello,
I am finding difficulty in producing the required result by using the following Query in Reports 6i
(Note: - The query actual output and the required output are as follows: -)
SELECT
DISTINCT
SH.S_HEAD_CODE,
B.BILL_ID,
B.SANCTION_DATE,
E.EMP_NAME,
E.EMP_DESIGNATION,
B.TOTAL_BILL,
NVL((SH.INITIAL_ALLOCATION-B.TOTAL_BILL), 0) BALANCE
FROM BILL B, PARAMETERS P,SUB_HEAD SH, EMPLOYEES E, BILL_DETAIL BD
WHERE
SH.S_HEAD_CODE=B.S_HEAD_CODE
AND B.S_HEAD_CODE=BD.S_HEAD_CODE
AND B.EMP_ID_NO=E.EMP_ID_NO
AND B.BILL_ID=BD.BILL_ID
The Output of the above query is as follows: -
Let say we have Total Amount Sanctioned Rs. 15,000,00/-
Name Total Bill (Rs.) Balance (Rs.)
Sohail 7147 1492853
Saqib 2131 1497869
Amir 6802 1493198
Shafiq 1214 1498786
Note:- In the above output the above query is subtracting the current balance from Total Sanctioned Amount (Rs. 1500000) each time, but
it should actually subtract the current bill amount from the previous balance like the below said result.
Name Total Bill (Rs.) Balance (Rs.)
Sohail 7147 1492853 {Previous Balance - Current Bill Amount (1500000-7147) }........ The previous balance was actual amount Rs. 1500000
Saqib 2131 1490722 {Previous Balance - Current Bill Amount (1492853 - 2131)}
Amir 6802 1483920 {Previous Balance - Current Bill Amount (1490722 - 6802)}
Shafiq 1214 1482706 {Previous Balance - Current Bill Amount (1483920 - 1214)}
Results Continue...........................
Please help me to solve this problem.
