How to Assign a Field value to a Variable??

Dear All,
Kindly let me know, if <b>"HOW TO ASSIGN A FIELD VALUE TO A VARIABLE????"</b>
Situation is, we have a Field (OBJK-TASER) in which 2 tables (SER01 & SER03) are stored. And we want to access names of the Tables which are there in the field(TASER) in (OBJK) table to a variable and then passing that variable to the sql query as a table name to get data accessed dynamicaly.

try this

Avoid Global Public variables...

Hello Experts,
I have declared few variables in package specification (l_test , l_test_2)and i'm using across the API procedures.
But when i run the TOAD expert it says "Avoid defining global public variables in the package specification."
So i thought of moving the code from package specification to package body...
Is this a good approach and will my code work as it was working before if i declare in the body...
Plz suggest ...
Thanks...
Earlier
Package Specification Part
CREATE OR REPLACE PACKAGE PKG_TEST
AS
l_test NUMBER(1);
l_test_2 NUMBER(2);
END;New
CREATE OR REPLACE PACKAGE BODY PKG_TEST
AS
l_test NUMBER(1);
l_test_2 NUMBER(2);
   PROCEDURE process
   IS
   END process ;
   PROCEDURE process_2
   IS
   END process_2 ;
END PKG_TEST;

Linus,
Just so you are aware, the scope of those variables are different depending on if they are defined in the PACKAGE (SPEC) or PACKAGE BODY.
Declared in the PACKAGE (Spec): Globally accessible to everything on the Schema.
Declared in the PACKAGE (Body): Globally accessible to everything with that particular Package.
So as you can see, this quite a big difference. TOAD is warning you because putting globals in the PACKAGE is a pretty sloppy coding practice that can easily lead to difficult to maintain code. While you can ignore it, I'd suggest not doing that. ;)
In fact, I'd suggest avoiding globals altogether when possible. Passing parameters may be more time consuming, but it makes it very clear what each procedure/function should be doing, and future programmers will thank you. Time you'll save on initial programming will be made up when doing maintenance. But admittedly globals are useful, just be careful when using them. Getting your code to work isn't enough; you should aim to make it clear and understandable too.

How to declare a global/public variable in Oracle Forms

Hi All,
I have to get the value of a variable which is declared in the event 'When_Button_Pressed', in an another trigger with in the form.
My variable & type
l_db_handle EXEC_SQL.ConnType;
This variable used to get the handle of a new database connection.
(Here I am trying to make connection to two different databases from Form. That is working fine.)
I have tried with Global variable to transfer this variable value to other triggers. But it is not working. It shows 'Wrong type error'
Could you please let me know, how can I declare which DB handle variable as public in form(I mean i have to use this variable all the triggers with in the form)
Thanking You,
Manu

Put the code in a package within the form, have the triggers call functions/procedures within the package. All variables which need to be referenced in more than one procedure can be created as package variables.

[b]how to assign whole expression to a temporary variable[/b][/b]

Good afternun. Can someone help me how to assign the whole expression to a temporary variable. The expression is
id = catDao.findByPK(info.getCategoryId());
Thanks in advance and may I know how to validate the temporary variable?

You can do this with an anonymous class and a command pattern.
interface LazyEval {
public Object getValue();
LazyEval le = new LazyEval() {
public Object getValue() {
return catDao.findByPK(info.getCategoryId());
id = le.getValue();However, this sound like a solution to a problem which should be done another way.

How to assign bean value to a local variable in JSP using struts.

Hi everybody!
I've a problem that puzzled me on how to assign a bean value to a local variable like String in JSP using struts.
we can have someting like this to display the value
<bean:write name="detailService" property="status" />or
<bean:define id="theStatus" name="detailService" property="status"/>
This is country: <%=theStatus%>but an error occured when I tried like this:
String currentStatus = "<bean:define id="theStatus" name="detailService" property="status"/>";
or
String currentStatus = "<bean:write name="detailService" property="status" />";Is there a way to do this?.....
Any help pretty much appreciated

Java != JSP.
The <bean:define> and <bean:write> tags are custom tags meant to appear in the HTML section of a JSP file, as opposed to the scriptlet section. They actually get turned into java code as part of the translation process.
The <bean:write> tag naturally just writes out what you tell it to.
The <bean:define> tag defines a local variable, and gives it a value.
this should do it.
<bean:define id="theStatus" name="detailService" property="status" type="java.lang.String"/>
<%
String currentStatus = theStatus;
%>With the advent of JSTL, you shouldn't really need to use scriptlet code anymore. Personally I am for 0% scriptlet code in any jsp I write.

How to assign a sql statement to a variable

hey
i am assigning a sql statement into a variable. But in sql statement where condition i am passing a variable, i am getting syntax error while processing this statement . Could please help me
my code is like this
sSql:='select id from SOURCES where name=' || vc_arr(i);
Open C for sSql;
....

If you use bind variables, you don't need the single quotes, and may avoid significant performance and security problems otherwise associated with dynamic SQL.
sSql := 'select id from SOURCES where name = :some_value';
OPEN C FOR sSql USING vc_arr(i);

How to assign a value to the page variable to enable partial page rendering

This is part of my code:
<bc4j:rootAppModuleScope name="App1"
rendered="on@ctrl:page">
Now, I want to change the value of "on@ctrl:page" to "true" after user click a button so that part of the page will be displayed. But how do I assign the value to "on@ctrl:page". I tried to put the followings in my even handler:
<bc4j:setPageProperty name="on" value="true">
<bc4j:parameter name="on" />
</bc4j:setPageProperty>
But it doesn't work. Could someone pls tell me how I should do it.
Thanks a lot!
Ling

You should do is:
in your event handle codes,you add the list:
public static EventResult eventname(
BajaContext context,
Page page,
PageEvent event) throws Throwable
EventResult result = new EventResult(page);
result.setProperty("on","true");//or "false"
return result;
then,
change
rendered="on@ctrl:page" -> data:rendered="on@ctrl:eventResult"
also ,you should see the 5th part of 'UIX Developer's Help'

How can I detect if a global bolean variable has changed

I have a boolean global variable that change its value from time to time. At hte beginning of my program I take the actual time, but everytime this value change I have to reset this previous value and take the actual one. I've tried to do this with the event structure but it doesn't work because this is a global variable and not a control in the panel. Some idea to solve this problem? Thanks in advance,
Angel

It's mainly because you are reading value change events for the indicator, not the control. Value change events are only fired for changes given by a user. The indicator however is not updated by the GUI, but by programmatic input from the control. By replacing the reference with a reference to the control it will work. Or you can write the value to the indicator by using a Value (Signaling) property, that will trigger a change event for the indicator.
Note: You should not register the event inside the loop, do that only once - outside the loop.
If the boolean you are to monitor is not changed from the GUI you can as I mentioned above make it fire an event by setting the value using the value signalling property inst
ead of wiring the new value directly, but the property node has it's downsides so another option is to create a user event, put that reference in the global, and then run the generate user event function whenever the boolean changes.
I see you read the ms timer when the value changes. Why? If you want the time get the time, if you want the time since the last update you could use the ms timer, keep the previous value in a shift register and then calculate the difference, but the ms timer rolls over now and then so that can give false results...What is the purpose of the time and how often does the value change?
Attached is an exmaple that use a user event and the generate event function.

How to assign DOT ( current context ) to a variable ?

If i use XML dot (.) within Href , i am getting current context (http://servername/test)
Like this -->
<TD>
<xsl:element name="a">
<xsl:attribute name="href">./</xsl:attribute>
<xsl:value-of select="NAME" />
</xsl:element>
</TD>
But if i try to assign dot to a variable ,variable is not picking up the current context.
How can do this ?

<xsl:variable name="a" select="."/>
Usually this is not necessary, since you can refer to the current context using the current() function.

How to assign value from insert statement to variable from a trigger

Hi,
I got this really annoying problem and I don't know if I am doing it correctly.
I have a BEFORE INSERT trigger on a table. When someone executes an insert statement I want to grab the value of a column from that statement and assign it to a variable and then do stuff with it. I'm stuck on the assignment.. look below..
CREATE OR REPLACE TRIGGER CARS.geotest2_trigger
BEFORE INSERT ON CARS.GEO_TEST2
FOR EACH ROW
DECLARE
v_chainkey nchar(32);
v_chainkey2 nchar(32);
not_exists EXCEPTION;
BEGIN
:NEW.CHAINKEY := v_chainkey;
SELECT GEO_TEST.CHAINKEY INTO v_chainkey2 FROM GEO_TEST WHERE GEO_TEST.CHAINKEY = v_chainkey;
IF v_chainkey2 = '' or v_chainkey2 is null THEN
RAISE not_exists;
ELSE
INSERT INTO GEO_TEST2 VALUES(:NEW.CHAINKEY, :NEW.BLA, :NEW.FOO);
END IF;
EXCEPTION
WHEN not_exists THEN
RAISE_APPLICATION_ERROR(-20010, 'Chainkey does not exist in parent table GEO_TEST');
END;
I keep getting this error
Error: ORA-04098: trigger 'CARS.GEOTEST2_TRIGGER' is invalid and failed re-validation
SQLState: 42000
ErrorCode: 4098

It isn't assigning because v_chainkey is not at the left hand side of the assignment statement.

I think the sole purpose of that "not_exists" exception is this -
If you try to insert a NULL value for GEO_TEST2.CHAINKEY, then this trigger will throw an error even if at least one NULL value exists in GEO_TEST.CHAINKEY column.
Not sure if that's something that you wanted.

Referencing package public variables remotely

According to Oracle 8i documentation, its not possible to reference - directly or indirectly - package global public variables remotely. This implies the construct <package_name>.<public_variable_name>@<remote_database> doesn't work. The only way possible is to create public functions in the remote package to return the value of the variable. (e.g. function return_variable return <public_variable_name>%type is begin return <public_variable_name>; end;)
Can anyone please confirm this, otherwise suggest any other simpler way of accessing remote package variables?
Thanks.

Rahul,
No unfortunately you can't get at them, nor can you get any constants. It sure would be a good thing if you could, but I use the following to get around this problem as getting global variables and constants is a very important thing. This method I've shown below actually works pretty slick and it uses a remote function and a view to get the job done.
I actually like how this works better than calling a variable/constant directly. The example below I just did up, but it shows the basic idea. Basically you put a number beside your var/const as a comment marker. I usually use a sequence to keep track of the numbers I've assigned. A test package was made that has 1 variable and 1 constant. A function is made that gets these values. A view is made that calls this function and returns ALL of the variable and constant values. You can take this even further and have it return the actual variable/constant name itself as well.
I like doing it this way as you now only have ONE entry point (the view) to get as many variables/constants as you like, even if spread across multiple packages. I have my own code that does all of this, but the example below gives you an idea of how to make one yourself. Remember this is just a simple example, you can make it so you don't have to do the union in the view, and you can make the function return more things if you like, but I'm kinda short on time so my example is pretty simple, but it works quite well.
The following is from the Oracle docs telling you about trying to get remote values ...
--[START]
http://otn.oracle.com/docs/products/oracle9i/doc_library/901_doc/appdev.901/a88876/adg10pck.htm#2501
Remote Procedure Calls and Parameter Values
You must explicitly pass values to all remote procedure parameters, even if there are defaults. You cannot access remote package variables and constants.

Ok here's the code and some output ...

With session.setAttribute("name",object) you can store a Attribute in the session object.
with session.getAttribute("name") you can get it.
