UPDATE Database (using Schema) based on current START_DATE_TIME

Hi,
I am using the TestStand Schema and a MYSQL datababse.
I have added a new table the MYSQL database that comes with TestStand. I am using the database tools to insert some local variable results into this table.
I also add the start date and time to this table, using
Str(RunState.Root.RunState.Sequence.Locals.StartDate.Month) + "-" +Str(RunState.Root.RunState.Sequence.Locals.StartDate.MonthDay) + "-" + Str(RunState.Root.RunState.Sequence.Locals.StartDate.Year) + " " + Str(RunState.Root.RunState.Sequence.Locals.StartTime.Hours) + ":" +Str(RunState.Root.RunState.Sequence.Locals.StartTime.Minutes) + ":" + Str(RunState.Root.RunState.Sequence.Locals.StartTime.Seconds)
I am trying to use the Schemato update the a colum with the parent ID, so I have it set up as a foreign key. I can get this to work when I use hardcode the the date/time in the SQP statement.
Example:
"UPDATE UUT_CTO_DATA SET ID=? ,UUT_RESULT=? where START_DATE_TIME='2009-03-20 15:13:24'"However I would like to change this so the SQL statement using the TestSTand Variables to figure out which is the current record to update...Is this possible..All help is greatly appreciated.

Don1.

Hi Mark,
Thanks for the quick response,Some comments below:
I need some clarification on the issue and your progress. In the first poast you had said "I can get this to work when I use hardcode the the date/time in the SQP statement." When you hardcode the date and time, does it update the ID & UUT_RESULT columns for all devices in a bath?
When I hardcode the update SQL statement with a specific date, Example: "UPDATE UUT_CTO_DATA SET ID=? ,UUT_RESULT=? where START_DATE_TIME= '2009-03-24 10:31:13'" , it will update the ID & UUT_RESULT columns for all devices in a batch, (I manually delete it from the MYSQL database after each device in the batch to confirm it updates on subsquent runs)
So do you think it now looks like my original SQL statement is somehow incorrect for all bar the first device in the batch?
I did try the following:
Created a StationGlobal called Test.
Assigned it as follows, to ensure it matches the database record format ('2009-03-24 10:31:13')
StationGlobals.Test =Str(RunState.Root.RunState.Sequence.Locals.StartDate.Year) + "-" +Str(RunState.Root.RunState.Sequence.Locals.StartDate.Month,"%02i") + "-" + Str(RunState.Root.RunState.Sequence.Locals.StartDate.MonthDay,"%02i") + " " + Str(RunState.Root.RunState.Sequence.Locals.StartTime.Hours,"%02i") + ":" +Str(RunState.Root.RunState.Sequence.Locals.StartTime.Minutes,"%02i") + ":" + Str(RunState.Root.RunState.Sequence.Locals.StartTime.Seconds,"%02i")
Change my SQL statement to "UPDATE UUT_CTO_DATA SET ID=? ,UUT_RESULT=? where START_DATE_TIME= '"+StationGlobals.Test+"'"
As before it updated for the first device in the batch and none of the rest.
Also, which version of TestStand are you using?
I am using TestStand 4.1.1
Thanks & Regards,

How to update database using Service in 11g

Please some one provide the knowledge, how i will update database from a form and form is having multiple rows and column and and all are having different or same value.

Hi ,
If you are looking to update the fields for a user such as description , telephone number etc then the following service needs to be used :

Update Database using Materialized Views

I have a need to update the database across the firewall (on a partner network). Are there any issues/problems with this approach like performance, security,etc. I do not want to use dblinks.

Materialized views generally don't work too well without a database link between the machines-- in fact, they don't work at all. Oracle replication is built around the assumption that the databases involved can communicate with each other.

Unable to update database using a remote bean call

We have a system, in which one of the EJBs (say, local EJB) in one
system remotely call an ejb (say, remote EJB) on another system. The
problem is the that the remote EJB is unable to database with any
changes when its method was invoked by the local EJB.
We first call a set method which is supposed to update the DB. Then we
call the get method which returns the recently updated value. However
the data is not stored in the DB. The get method seems to retrieve the
data from the cache. There is no exception thrown.
However there is no issue with the remote EJB. If we call the method
locally, it DOES update the database. I dont know if it has to do
anything with the java security policy defined. We use Weblogic 6.1
SP3.
We have a release in another 2 days and any help on this will be
appreciated.

Update database using check boxes

I have a query region that produces a checkbox and an associated line with the checkbox. The data in the database that is a "Y", produces a checked box.
select check_box_seq,
htmldb_item.checkbox(1,is_it_checked,decode(is_it_checked,'Y','CHECKED')) D,
check_box_text R
from check_box_tbl
What I need to happen is to change one or more check boxes. I have a MultiRow Update process, with a process point of On Submit - After Computations and Validations with a PL/SQL conditional processing of:
FOR I in 1.. HTMLDB_APPLICATION.F_F01.COUNT LOOP
update table check_box_tbl set is_it_checked = Y
where check_box_seq = htmldb_item.application.g_f01(i);
END LOOP;
But the data in the database does not change. I have read numerous discussion on this thread but I have not found exactly what I need or can not recognize it.
How can I get the data in the database to change when I either change a checked box or after I have changed all boxes and then press the SUBMIT.

I am having a similar problem that I cannot find the answer to. (See my process below). I don't think that the process is "grabbing" the checked values in the SDN column. It is using NULL, so therefore no rows are being inserted in the table. Shg_id and SDN are both primary keys in this table, so I need to insert both. Shg_id has an assigned value already.
My process is this:
DECLARE
l_selected HTMLDB_APPLICATION_GLOBAL.VC_ARR2;
BEGIN
l_selected := HTMLDB_UTIL.STRING_TO_TABLE(:P312_SDN);
FOR i IN 1..l_selected.count
LOOP
INSERT INTO shgm (Shg_id, SDN)
VALUES (:P312_Shg_id, l_selected (i));
END LOOP;
END;

Rahul,

Not necessary. UPDATE can be asynch as well.
Can you turn the trace on like pointed by Michal and then you can see the Query in the Audit Log of the adapter montioring. Try to execute the same query from your DB Client like TOAD and see what is the Syntax error you are getiing.!
The problem looks like some field has some dataype / column name mismatch.

How to connect to database using sqlplusW (windows based sqlPlus)

Hi
Thank you for reading my post
I did some search and i find that i should use some kind of SYSTEM/SYSTEM@ORCLE
to connect to database using windows based sqlplus.
in the above SYSTEM is username and password and ORCLE is SID.
but sqlplusw says that
could not resolve the connect identifier specified.
where i can find complete information about HOST string ?
thanks

You can look inside yours tnsnames.ora file it can be found in %ORACLE_HOME%\network\admin
MOB92 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = xxx)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = MOB92.world)
Here my network service name in MOB92 so in sqlplus I would use:
system
password
mob92
and it should work. If you have no such entry in tnsnames.ora file you can use for example Network Configuration Assistant to configure your network service name.

Performance on Schema based Xml and No Schema based XML

Hai,
We can insert two kind of xml like schema based xml document and non schema based xml document into XMLTYPE fields.I like to know which xml document will have good performance ( fast access ) compare to another.
Even if we have any other approach than schema.It will be great.
We do XPath query to get the values from xml document.Is there any way to get the fields faster than the XPath.I am using Oracle 10g R2.
I need to access much fast the xml element from the table.Please help me!.
Thanks,
Saravanan.P

HHave you read the FAQ or any of the XML DB whitepapers... If not I suggest that you do so before proceeding any further or asking any more questions. If you take the time to a do a little basic research you should be able to see that you have made the worst possible decision if performance is importantto you.
If you invested a little bit of effort before posting you would soon understand that in 10gR2 you will need to use schema based storage to get high performance, and that it doesn't matter whether you use XPath or XQuery, what matters is whether or not the XPath or XQuery operations get re-written correctly so the database can optimize them.

How to access Oracle Using Dos Based FoxPro(2.5,2.6)

Hello Sir,
I need some clarification regarding the following question.
Q. How can access Oracle Database using Dos Based Foxpro of version either 2.5 or 2.6
Thanking you,
Kishore.P

Hi Alex,
the host and port depends on your network setup of your VM.
Do an ifconfig -a and see what IP adress your guest has.
With this IP address you should be able to access EM from outside your VM (but on the VM host, not from outside the network) with the same port.

Function in SQL: PRAGMA used, but '..does not guarantee not to update database'- WHY?

I use function in SQL statement. It is a dynamicaly build SQL, therefore I need overload functions. These funcs defined in package. The package has PRAGMA Restrict_References (.., WNDS). So all functions should be restricted to update database.
But Oracle returns an error:
Function NVL_ does not guarantee not to update database
This is my build SQL:
----- the execution string is: ---------------

Can anybody help : where is a problem and what I can do in my case?
I work in Oracle 7.3
Thank you,
Alex

Hi Alex,
I've found that on the RDBS docs:
If you specify DEFAULT instead of a function name, the pragma applies to all functions in the package spec or object type spec (including, in the latter case, the
system-defined constructor). You can still declare the pragma for individual functions. Such pragmas override the default pragma.
Try using that and let me know.
The docs says also that the declaration of the pragma for an overloaded function applies to the nearest one. You may also try to insert several declaration, one after every function declaration.
Bye Max

Updating a database using EJB Inheritance

I am new to EJB's, so please forgive my ignorance. I creating the following classes that inherit from each other along with a method to update my database:
@Entity
@Inheritance(strategy = InheritanceType.JOINED)
@DiscriminatorColumn(name="TYPE", discriminatorType=DiscriminatorType.STRING)
public abstract class ObjectA implements java.io.Serializable {
     protected String name;
     protected String desc;
     protected String type;
@Entity
@DiscriminatorValue("OBJECTB")
public class ObjectB extends ObjectA implements java.io.Serializable {
     protected String str_b;
     public ObjectB(String name, String desc, String type, String str_b) {
          this.name = name;
          this.desc = desc;
          this.type = type;
          this.str_b = str_b;
@Entity
@DiscriminatorValue("OBJECTC")
public class ObjectC extends ObjectB implements java.io.Serializable {
     private String str_c;
     public ObjectC(String name, String desc, String type, String str_b, String str_c) {
          this.name = name;
          this.desc = desc;
          this.type = type;
          this.str_b = str_b;
          this.str_c = str_c;
public class MyFacade implements ServletContextListener {
     @PersistenceUnit(unitName="Pu")
    private EntityManagerFactory emf;
    @Resource
    private UserTransaction utx;
    public MyFacade() { }
    public void contextDestroyed(ServletContextEvent sce) {
        if (emf.isOpen()) emf.close();
    public void contextInitialized(ServletContextEvent sce) {
        ServletContext context = sce.getServletContext();
        context.setAttribute("MyFacade", this);
     public void updateObject(ObjectA obj) {
        EntityManager em = emf.createEntityManager();
        try{
            utx.begin();
            em.merge(obj);
            utx.commit();
        } catch(Exception exe){
            try {
                utx.rollback();
            } catch (Exception e) {}
            throw new RuntimeException("Error updating obj", exe);
        } finally {
            em.close();
}If I do the following:
     String name = "test name";
     String desc = "updating object c";
     String type = "OBJECTC";
     String b = "b";
     String c = "c";
     MyFacade myf = new MyFacade();
     ObjectC objC = new ObjectC(name, desc, type, b, c);
     myf.updateObject(objC);
     .....In my database, only the values associated with ObjectC get updated and nothing from ObjectA or ObjectB get updated in the database. Does the "merge" method not work on inheritance. How do I update my database using inheritance?
Thanks!

did you only have ISQL for testing it?
Can you debug the form and look, if someone happens - exceptions, ... ?
after the update you can use
message (SQL%ROWCOUNT); pause ;
to look, how many records were updated

Read from database (Access) and update fields using MS ADODB

Hello,
I am trying to get records from database using MS ADODB._connection & ADODB._Recordset objects (from LabVIEW 6)
I can:
1. open connection (with ADODB._connection)
2. write into tables (with ADODB._command)
I can not: gets records and update fields using ADODB._connection & ADODB._Recordset.
I do not know:
1. how to connect between the connection that was opened and the recordset object
2. where I can write the SQL text as input to the recordset
Attached is DataBase.llb with DB_read.vi that display my steps.
Thanks.

Try this one, after updating the names for database and the table you want.
Let me know if it's working.
p.s.: if you have problems, it could be a different adodb version ... but the sequence of methods is the same

My requirement is to update 3 valuesets daily based on data coming to my staging table. What is the API used for this and how to map any API to our staging table? I am totally new to oracle and apps. Please help. Thanks!

My requirement is to update 3 valuesets daily based on data coming to my staging table. What is the API used for this and how to map any API to our staging table? I am totally new to oracle and apps. Please help. Thanks!

Hi,
You could use FND_FLEX_LOADER_APIS.UP_VALUE_SET_VALUE to upload them from staging table (I suppose you mean value set values...).
You can find a sample scripts if you google around.
What do you mean "how to map any API to our staging table" ?
You should do at least the following mapping (which column(s) in the staging table will provide these information):
- the 3 value sets name which you're going to update/upload (I suppose these are existing value sets or which have been already created)
- the value set values and description
Try to start with something and if there is any issues the community could then help... but for the time being with the description of the problem you have provided, that's the best I can do...
