Bind variables in the APEX
HelloCould you please comment on this syntax, step by step, please:
'%' || : SEARCH_STRING. '%'
I need to know what it does and why are these characters: '%' and |
Thank you very much in advance...
Hello
SEARCH_STRING is variable defined at the page or application level and is "%" padding for the SQL LIKE operator where you say something like finding any name that has 'SAM' in it.
WHERE NAME LIKE '%SAM%'
In order to build this dynamic condition you can have a variable to store the value SAM (SEARCH_STRING) and then in the WHERE clause, you can say "%" | : SEARCH_STRING. '%' (| is a concatenation operator).
I hope this helps.
Thank you

problem with bind variables in the SQL query view object
Hi all
I use JDev 11.1.2.4.0.
I have a problem with bind variables in the SQL query view object.
This is my original SQL
SELECT sum(t.TIME) , t.legertype_id FROM LEDGER t WHERE t.nctuser_id = '20022' AND to_char(t.insertdate,'YYYYMMDD') in ('20130930','20130929') group by t.legertype_idIn my view .xml object query tab, I am writing this
SELECT sum(t.TIME) , t.legertype_id FROM LEDGER t WHERE t.nctuser_id = '20022' AND to_char(t.insertdate,'YYYYMMDD') in :dddd group by t.legertype_id
Davis here is a variable of Type liaison: String, updatable and necessary.
I try to deal with Davis as ('20130930 ', ' 20130929') hoping the view object, run as my original SQL.
But failed. The view object retrieves 0 line after that I run.
Why?
Thank you! ('2original SQL0130930', '20130929') ('20130930 ', ' 20130929')
A variable binding cannot be used as this is why you must use years table. Check decompilation binary ADF: using oracle.jbo.domain.Array with ViewCriteria to see a solution.

bind variables using the values in the collection
Hi the gems... Good afternoon...
Can we not use plsql values in the collection in the USING clause to pass the bind variable values...
I wrote the procedure to kill all sessions that cross the parameter OPEN_CURSORS below. the query, I found only three sessions that exceed. But when I execute my procedure so those are not removed, execution gives me an error also. He simply executed but no session has been killed.
My part of the code is as below:
However, when I replace the bind variable with the values in the collection, then it works:.......... .......... .......... OPEN rc FOR v_sql; FETCH rc BULK COLLECT INTO v_tt_sessions; LOOP EXIT WHEN v_tt_sessions.COUNT = 0; FOR idx IN 1 .. v_tt_sessions.COUNT LOOP EXECUTE IMMEDIATE 'alter system kill session '':a,:b'' immediate' USING v_tt_sessions(idx).sid, v_tt_sessions(idx).serial#; END LOOP; END LOOP; CLOSE rc; ......... .........
Please suggest if there is something wrong in my code first. I tried, but could not get any inadequacy........... .......... .......... OPEN rc FOR v_sql; FETCH rc BULK COLLECT INTO v_tt_sessions; LOOP EXIT WHEN v_tt_sessions.COUNT = 0; FOR idx IN 1 .. v_tt_sessions.COUNT LOOP EXECUTE IMMEDIATE 'alter system kill session '''||v_tt_sessions(idx).sid||','||v_tt_sessions(idx).serial#||''' immediate'; END LOOP; END LOOP; CLOSE rc; .......... ..........But the doubt is when I removed the variable of liaison with the values of the collection hard-coded (in my first post), then this process works very well. But I want to use bind variables.
You cannot use bind variables in this situation. You can use bind variables for the DML statements.
I'm surprised that you have no error, but I guess that this block of code explains everything:EXCEPTION WHEN OTHERS THEN dbms_output.put_line(SQLCODE || ' : ' || SQLERRM);You concatenate values to build a single command ALTER SYSTEM and run, just like your second attempt.
You don't need to have a dynamic cursor either.for r in ( select v.SID, u.serial#, count(v.sid) from v$open_cursor v, v$session u where v.CURSOR_TYPE='OPEN' and v.sid=u.sid group by v.sid, u.serial# having count(v.sid)>190 order by count(*) desc ) loop execute immediate 'alter system kill session '''||r.sid||','||r.serial#||''' immediate'; end loop;And of course, I agree with the comments of Keith (assuming that this is not just an exercise).

The use of bind variables in the application process
Bind variables refer to elements of session state supported in queries in an application request process?
All the examples I see show how to pass client side values using the $v () function and the htmldb_get object addParam method and refer to them using the wwv_flow.g_xNN variables, but already available in session state values, I should be able to use them directly in the process, right?
Thank youYes, they are supported.

Bind Variables on the view objects child definition
JDeveloper 12 c
I have an interesting question. I have a view (AisWebModulePrivsVO) object that uses a bindvariable hardcoded in the view object.
SELECT * FROM SYS. DBA_ROLE_PRIVS where DEALER =: bvUserName
If I put this in the request module I can programmatically set the variable binding (view object contains the getter/setter for the binding variable).
AisWebModulePrivsVOImpl voTest = am.getAisWebModulePrivsVI ();
voTest.setbvUserName ("ARAWLS");
voTest.executeQuery ();
System.out.println ("test reports:" + voTest.getRowCount ());
and get the correct number of records based on return on the user and database roles. If it works.
What does NOT work, it is when this display object is a recording of 'the child' to another display object (as specified by a link between the two and by setting the object from a point of view as one child of the other in the module of the application).
AppModule looks like this:
CgRefCodesVO
AisWebModulePrivsVO
In this case, I have a view called cgRefCodeVO parent object. There is a link between this and the AisWebModulePrivsVO. The relationship works.
AISMenuAppModuleImpl m = ADFUtils.getApplicationModuleForDataControl (appMod) (AISMenuAppModuleImpl);
CgRefCodesVOImpl cgRefVO = am.getCgRefCodes1 ();
AisWebModulePrivsVOImpl modsVO = am.getAisWebModulePrivs1 ();
modsVO.setbvDBUserName ("ARAWLS"); This doesn't seem to work here...
cgRefVO.executeQuery ();
All lines rs = cgRefVO.getRowSet ();
RS. Reset();
While (rs.hasNext ()) {}
CgRefCodesVORowImpl CgRefRow = rs.next ((CgRefCodesVORowImpl));
System.out.println ("RvLowValue:" + CgRefRow.getAttribute ("RvLowValue"));
RowIterator aisModulesRowIter = CgRefRow.getAisWebModulePrivs ();
System.out.println ("number of children:" + aisModulesRowIter.getRowCount ());
}
The code compiles and runs. She translates: "County of the child: 0" for each row returned by the
I also tried:
VM VariableValueManager = modsVO.ensureVariableManager ();
vm.setVariableValue ("bvDBUserName", "ARAWLS");
And:
modsVO.setNamedWhereClauseParam ("bvDBUserName", "ARAWLS");
and (of ( )
@Override
protected void executeQueryForCollection (Object, object, Object [] object2, int i) {}
I coded everything hard to see if it would work.
setNamedWhereClauseParam ("bvDBUserName", "ARAWLS");
super.executeQueryForCollection (object, object2, i);
}
and from there, I changed around the order to execute the objects in view.
How can I set the variable binding in the object view child?
Thank you
Stuart
It is an interesting example how ADF works up to a certain point... then you need to start to make cuts to modify its behavior as you wish.
I decided that it was just easier to delete 'the child' parent (in the app module) and create a view of criteria on this subject for what would basically query the records to get the same results, like a child.
Perhaps not as elegant, but so much easier.
Thanks for your help.

When I go from ODP.NET to the ODP.NET managed some of my questions begins to throw errors missing bind variable.
I reproduced with a simple example that uses a variable called liaison: unitName
It's the example SQL:
SELECT
: unitName
Of
DOUBLE
Now, if I add a comment at the beginning of the SQL like this:
-Text with: unitName
SELECT
: unitName
Of
DOUBLE
It works, but if I have a variable binding in a comment that is located on a number of the 'same' line, I get ORA-01006:
This causes the error:
-First line comment
-Text with: unitName
SELECT
: unitName
Of
DOUBLE
Kind regards
-Tommy
I was able to reproduce this problem. I filed Bug 19433348 on your behalf.
The circumstances in which the bug occurs are fairly easy to get around.
(1) remove the colon in the second commented line.
(2) add a space between the '\n' and ' - '.
If you are one of those things, you won't encounter the bug behavior.

Procedure of the ODI - Bind Variables in the conditional statements
In an ODI procedure, is it possible to add a conditional statement around bind variable? For example, if I use OdiOutFile as the command on the target and Oracle as the command on the Source, I can use bind variables to fill the data in this table (we are in fact using OdiInvokeWebService and passing a XML structure very complex, but it's easier for testing):
OdiOutFile-FILE = C: / TEST. TXT
< person >
< first > #FIRSTNAME < / first >
< Middle > #MIDDLENAME < / Middle >
< last > #LASTNAME < / last >
< / person >
It is a way to add a conditional statement using one of these bind variables? For example, if I wanted to test #MIDDLENAME null and null value, produced this portion of XML, such as:
OdiOutFile-FILE = C: / TEST. TXT
< person >
< first > #FIRSTNAME < / first >
< % if (#MIDDLENAME! = null) {% >}
< Middle > #MIDDLENAME < / Middle >
< %} % >
< last > #LASTNAME < / last >
< / person >
This type of scriptlet syntax seems to work fine, as long as the binding variable is not in the mix (if I put "true is true" or "true == false" in the case, it shows or does not show this line in the XML file, as expected). I use ODI 11.1.1.7.0
----------------------
Post edited by: KevinPratt
Thanks for the reply! As suggested, in what follows, I changed the command and it works as you want
OdiOutFile-FILE = C: / TEST. TXT-APPEND
< person >
< first > #FIRSTNAME < / first >
< @ if (!) (("#MIDDLENAME".equals(""))) {@ >}
< Middle > #MIDDLENAME < / Middle >
{< @} @ >
< last > #LASTNAME < / last >
< / person >
Using the syntax <@ ...="" @="">serve your purpose. Also, I think you might want to include the variable binding in the quotation to avoid syntax errors.

JDev 11.1.2.1 method Execute (with bind variable) before the page is displayed
Hi all
I have a view object with a query that uses a variable binding. I drag the data on my .jsf page control to create a table. I create a query method on a bean in sight. The query method uses the content of one of the attributes of the bean to set the link for the query variable:
vo.setNamedWhereClauseParam ("CraIdBindVar", sessionBean.getCraId ());
I put a button on the page that calls the method of the request and it fills the table. That's fine, but I don't want the user to have to click the "query" button when browsing this page. I found forums dealing with create an AMImpl.jave method, create a link on the page, create an executable file for the link. It works that the method is executed until the page appears. However, the AMImpl method cannot call sessionBean.getCraid () to obtain the data required to complete the binding variable.
Is it possible to run my method of view range bean before the page is displayed? Or maybe a way for the AMImpl.java method to access the range of view variable?
Thank you, SteveSteve,
You can drag a call method on the workflow activity. Select the new method call activity, and open the property inspector. Here you choose your bean method in the method property. Now, first of all, you go to this activity of method call, then the page.Timo

Bind variables in the SQL causes slow
We have a strange problem in our PeopleSoft system that I traced to a SELECT statement using bind variables, if hardcode us them values in SQL, it runs very fast.
but using bindings (what the application does) a problem of efficiency. I'm going to re - write the code that is based on a view of three tables joined to go against
the base tables and I don't think I'll have a problem. However, I would like to know why the problem exists in the first place. Here is what info I have:

Using a Bind Variable in the FROM of a SQL statement part?
Hi all
I have a problem, I am trying to execute a SQL statement. However, I need the FROM part of the SQL statement in a variable binding. This is because the end user will have to choose between 2 views of database.
I tried this:
Select CON_ID from: P23_DB_NAME where CON_LEGACY_ID =: P23_CONLEG_NO
I had no chance. The error I got was,
'+ The query cannot be parsed in the generator. If you believe that your request is
syntactically correct, choose the generic "columns" box below the
the source of the region without analysis.
"ORA-00903: invalid table name +".
What makes sence, but now I'm a little stuck.
Does anyone have ideas for a workaround?
Thanks in advance.
-N.S.N.O.
The example I gave you is quite simple. You must take some time to study it to see where you need to be very careful what put you where. Now, of course your example does not work becaues you have several errors. It will work for you:
DECLARE x VARCHAR2 (4000); BEGIN x := x || 'SELECT CON_ID FROM '; x := x || :p23_db_name; x := x || ' WHERE CON_LEGACY_ID = ' || :p23_conleg_no; RETURN (x); END;Denes Kubicek

Get back information XMLSERIALIZE in a variable of the APEX...

What I'm not sure how is back with a variable chart_series_data PLSQL.
chart_series_data: = "< >". Chr (10);
chart_series_data: = chart_series_data | "WHAT I WENT BACK ON IT."
chart_series_data: = chart_series_data | Chr (10) | "< / data > ';

Use of bind variables in the repository
All,
Our client has a requirement that they need the sales this year of sales vs. last year passing year as a guest.
I can't use BI built in function to get early start or this year last year because our calendar dates are not standard. So I have to this day of dim query table to see e.g. for whats 2010 is the start date and so on...
To do this, I created a variable repository to hold these values using SQL. I want to know is can I use a binding to this SQL variable so that when the user passes year I can feed that year in this SQL and it will provide me with correct start and the end date for this year and last year.
Thanks in advanceYes. We can pass a value to what the user selects the guest. To do this you have create a session variable with "enable any user to set the value". Prompt properties for the year column choose "Ask the Variable" for whole Variable. And the use of content filtering year = ' valueof (NQ_SESSION.myVariable).
Let me know if it worked.
Kind regards

The use of bind variables in the HTML source region

I have problems integrating an element variable in an embedded HTML string that should popup a video mode when the button is pressed.

Hi fac586:You who modifies the code to use * $('_#foo').html ($v ('P1_SAVED_ITEM2')); * ?? If so, I think that solved my problem here. I tested it and it seems to work everytime now. Thank you
Yes. It was very late and I could not spend more time on a detailed explanation. foo is the static region ID, I assigned to the masked area of the HTML to use as a jQuery selector.
