Remove table filter before iterating over rows

Paul (MITsa)Feb 4 2025 — edited Feb 4 2025

JDeveloper 12.2.1.4

Hi

We are currently using the code below from Timo to remove table filters.
It works correctly. (thanks Timo)

public static void resetTableFilter(RichTable rt, Boolean refreshTable) {
FilterableQueryDescriptor queryDescriptor = (FilterableQueryDescriptor) rt.getFilterModel();
if (queryDescriptor != null && queryDescriptor.getFilterConjunctionCriterion() != null) {
ConjunctionCriterion cc = queryDescriptor.getFilterConjunctionCriterion();
List<Criterion> lc = cc.getCriterionList();
for (Criterion c : lc) {
if (c instanceof AttributeCriterion) {
AttributeCriterion ac = (AttributeCriterion) c;
ac.setValue(null);
}
}
if (refreshTable)
rt.queueEvent(new QueryEvent(rt, queryDescriptor));
}
}

The problem we have is that if the user applies a filter and we then iterate over the rows with a rowset iterator
the filter is still being applied.
Basically the user applies a filter, then clicks a button which calls a method in the application module.
in other words :

ViewObjectImpl vo = getOurView();
RowSetIterator rsi = vo.createRowSetIterator(null);

rsi.reset();
while (rsi.hasNext()) {
Row r = rsi.next();
… etc

We tried calling the above code in the button before calling the method in the application module before but it seems that the table refresh occurs too late (and gives a null pointer as when the user clicks on the button we are navigating away from the page)

We have also tried removing the viewcriteria ie.

for (String criteriaName : appliedCriteriaNames) {
System.out.println("------------------> Applied View Criteria: " + criteriaName);
// vo.getViewCriteriaManager().removeViewCriteria(criteriaName);
vo.getViewCriteriaManager().clearViewCriterias();

       }

But it does't seem to remove the filter on the VO

What's the best way to remove a table filter at the vo level before iterating over the rows.
Do we need to re-execute the vo ? If so how do we preserve uncommitted data ?

Thanks in advance
Paul

Check the error reported in “Control panel→System and Securities→Administrative Tools→Event Viewer” under Windows Log→Application.

How did you set the Instant Client path in PATH? In command prompt?

If you have set it in a command prompt, then make sure you start that command prompt as administrator (i.e. opening it by right clicking on command prompt icon and select “run as administrator” from popped context menu). Also, you should start ODBC data source administrator by executing “odbcad32” from that command prompt. Have you?

Yes I started the cmd as run as Administrator.

I am using ODBC 64 bit not 32 bit.

I set the path using Windows UI (System properties), and if I open a cmd window and type set I can see the correct path.

starting “odbcad32” from the command line did not help.

I tried the same process on a different computer and got the same results.

odbcad32 is for ODBC 64 bit on Windows x64 versions. You need to start odbcad32 from syswow64 directory to configure ODBC 32 bit on Windows x64 versions.

Have you checked the Application error logs in Event viewer? Did you find any error related to your ODBC application?

pczurak-JavaNet Oct 16 2024

I am running the 64bit version, if I start odbcad32 from syswow64 it starts the 32bit version.

There are no errors in the Event Viewer.

I have tried basic driver version 19.24, but when I click on the Test button, I get the following error:

---------------------------
Testing Connection
---------------------------
Unable to connect
SQLState=S1000
[Oracle][ODBC][Ora]ORA-12504: TNS:listener was not given the SERVICE_NAME in CONNECT_DATA

Looks like the service name is missing in your connection string.

Here is a sample of connection string:

sales=
(DESCRIPTION=
(ADDRESS= (PROTOCOL=tcp)(HOST=sales-server)(PORT=1521))
(CONNECT_DATA=
(SERVICE_NAME=sales.us.acme.com)))
The part that is highlighted with bold characters seems to be missing in your connection string. Fix it.

pczurak-JavaNet Oct 17 2024

This is what I am using.

JDEPRD =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = testoda0)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = jdeprd.test.com)
)
)

Are you able to connect to your database using SQL*Plus?

pczurak-JavaNet Oct 17 2024

No:

F:\instantclient_23_5>sqlplus

SQL*Plus: Release 19.0.0.0.0 - Production on Thu Oct 17 07:55:39 2024
Version 19.24.0.0.0

The issue is fixed

In the ODBC Driver Configuration.

For the TNS Service Name you cannot type the name even if you type it exactly as it shows in the dropdown, you must select it from the dropdown, otherwise it won't work.
