Hi all,
I am using Oracle Database 11.0.1 Enterprise edition.
I have 3 Tables Like FID_LIVE, NPR_LIVE, ARD_LIVE. These 3 tables receiving data. Once receive the data from these three table based on the condition i will insert the get_vep_count table. If already records is there like using the fid_live data after receiving the other two table data i will just update the field
Like below scenarios
1. FID -- Data received
if there is no record in GET_VEP_COUNT table Insert operation (Other 2 Operation update(NPR,ARD In get_Vep_count)
2. NPR_live data received
if there is no record in GET_VEP_COUNT table Insert operation (Other 2 Operation update(FID,ARD In get_Vep_count)
3. ARD_live data received
if there is no record in GET_VEP_COUNT table Insert operation (Other 2 Operation update(NPR,FID In get_Vep_count)
Below code based on logic i return if there is no update for maximum 60 seconds i will update timeout option.
Declare
 V_COUNT_FID NUMBER (1);
 V_COUNT_NPR NUMBER (1);
 V_COUNT_ARD_ID NUMBER (1);

 -- Check for further Inputs

 -- Check the Input
 SELECT CARD_ID
 INTO V_COUNT_CARD_ID
 FROM TABLE (GET_VEP_COUNT (P_LANE_ID));
 -- Timer
 V_INC_TIMER := V_INC_TIMER + V_SLEEP_TIMER;
 EXIT WHEN V_COUNT_CARD_ID = 1 OR V_INC_TIMER > V_MAX_ARDTIME;
 --- ard input or / Time Out update
 IF V_INC_TIMER = 60
 THEN
 UPDATE EXP_L1
SET ARD_STATUS = 'ard timeout',
 ARD_AC2_STATUS = 'ard timeout',
 ARD_TIMESTAMP = SYSDATE
 WHERE DECISION_STATUS = 'New' AND ARD_STATUS IS NULL;
 UPDATE EXP_L1
SET NPR_STATUS = 'Timeout', 
 NPR_TIMESTAMP = SYSDATE
 WHERE DECISION_STATUS = 'New' 
AND NPR_STATUS IS NULL;
 END IF;
 END IF;
End;
My problem is first records insertion is happen correctly but second table received any data need to update but it's not happen rather than it's insert other row. My condition one record only available in table once three records i updated i will delete the records form the get_v ep_count table. i used the sleep timer in above code once get the data from other 2 tables it's should update the records and terminate the sleep mode or else update the time out.
Thanks in advance.

We don't have your tables or data, so we can't run, test, or debug posted code.

See a picture of my car.

It doesn't work.

Tell me how to make my car go.

BTW - It is Worst Practice to store computed value in static table column.

Now I could be mistaken, but I believe the code could remain inside LOOP for around 1830 seconds; sum of 1,2,3,4,...,60)

Re: 2. How do I ask a question on the forums?

Anyone ever told you that Oracle is a multi-session, multi-user, and multi-transaction, processing platform?

Because your "solution" seems to be oblivious of these facts.

Too many things you don't explain what they are...

What I can't possibly know is what GET_VEP_COUNT does. Apparently it is some pipelined function, but who can tell what's behind that name.

If it's a pipelined function, then it looks quite strange to me the following:

SELECT FID, NPR, ARD_ID

        INTO V_COUNT_FID, V_COUNT_NPR, V_COUNT_ARD_ID

        FROM TABLE (VEP.GET_VEP_COUNT (P_ID));

and also

SELECT CARD_ID

INTO V_COUNT_CARD_ID

FROM TABLE (GET_VEP_COUNT (P_LANE_ID));

I say it looks strange because one would expect a pipelined function to return several records. And, if so, one would not select from a pipelined function into a single variable, like you do, for that will oftentimes raise exception too_many_rows.

Maybe it would make sense something like:

SELECT FID, NPR, ARD_ID

        INTO V_COUNT_FID, V_COUNT_NPR, V_COUNT_ARD_ID

        FROM TABLE (VEP.GET_VEP_COUNT (P_ID))

where rownum<=1;

That is you would select no more than one row. But, having only the information you gave, I can't be sure about anything.

One more thing is obvious to me: how do you handle the no_data_found exception? Because it may happen that that pipelined function returns no rows.

Therefore I can observe also no exception handling whatsoever.

While insert new record in table i started the sleep function it should 10 seconds waiting for update the another column  mean while data while update particular column then sleep function will exit or update function happen will happen "Timeout" (Exceed 10 seconds). ?

Now You understand how to make your car to go ?

"raise exception too_many_rows."

Return only one value. Now can you explain my question if you know means ?

Sounds Great.

So mark this thread as  ANSWERED.

You are mistaken - the variable passed to sleep is set to 1 and never changes.

You're going to have to explain what this code is supposed to do in a lot more detail.

You're also going to have to explain what it's actually doing in a lot more detail.

Probably with examples.

That sentence above really doesn't mean anything to us - it looks like there are lots of words missing.

Below for simple script  : 

create table TEST (EVENT_TI1 varchar2(15), EVENT_TI2 varchar2(15));

insert into TEST (EVENT_TI1) values ('event 1 Received wating for event 2 data');

EVENT_TI1 column Inserted waiting for EVENT_TI2  update statement maximum 5 second to update the  EVENT_TI2. if Data Is not received with in 5 second i will update the EVENT_TI2 Colum 'Timeout';

( or )

insert into TEST (EVENT_TI2) values ('event 2 Received waiting for event 1 data');

EVENT_TI2 column Inserted waiting for update statement maximum 20 second to update the EVENT_TI1. if Data Is not received with in 20 second i will update the EVENT_TI1 Column 'Timeout';

So only i enabled the sleep function to wait for 5 seconds if COLUMN 2 - EVENT_TI2 OR 60 SECONDS.

Note : BOTH THE DATA NOT RECEIVED SAME TIME. Either first column or second column.

Thanks

M.Bro.

How on earth do you expect that script to be helpful?

The code you posted does not refer to a table called test at any point, nor does it refer to columns event_ti1 or event_t2i.

Not only that but it's rubbish in and of itself:

SQL> create table TEST (EVENT_TI1 varchar2(15), EVENT_TI2 varchar2(15));
Table created
SQL> insert into TEST (EVENT_TI1) values ('event 1 Received wating for event 2 data');
insert into TEST (EVENT_TI1) values ('event 1 Received wating for event 2 data')
ORA-12899: value too large for column "LIVE"."TEST"."EVENT_TI1" (actual: 40, maximum: 15)

We ask people to post create table / insert scripts so we can recreate the data they have to come up with solutions to their problem.

Your script is utterly useless for that in every conceivable way.

It also helps to format code properly (and you should be properly formatting code every time you write it so you shouldn't need to do anything to it before posting here).

Here's your code formatted:

  V_COUNT_NPR      NUMBER (1);
  V_COUNT_ARD_ID   NUMBER (1);

  -- Max Intervals

  V_MAX_FIDTIME    NUMBER (2) := 6;
  -- Sleep Timers
  V_INC_TIMER       NUMBER (2) := 0;

    -- 60 Seconds Wait Logic for ard info
    LOOP
      DBMS_LOCK.SLEEP (V_SLEEP_TIMER);
      -- Check the Input
      SELECT CARD_ID
      INTO V_COUNT_CARD_ID
      FROM TABLE (GET_VEP_COUNT (P_LANE_ID));
      -- Timer
      V_INC_TIMER := V_INC_TIMER + V_SLEEP_TIMER;
      EXIT WHEN V_COUNT_CARD_ID = 1 OR V_INC_TIMER > V_MAX_ARDTIME;
      --- ard input or / Time Out update
      IF V_INC_TIMER = 60 THEN
        UPDATE EXP_L1
        SET ARD_STATUS = 'ard timeout',
            ARD_AC2_STATUS =  'ard timeout',
            ARD_TIMESTAMP = SYSDATE
        WHERE DECISION_STATUS = 'New' AND ARD_STATUS IS NULL;
        UPDATE EXP_L1
        SET NPR_STATUS = 'Timeout',
            NPR_TIMESTAMP = SYSDATE
        WHERE DECISION_STATUS = 'New'
        AND NPR_STATUS IS NULL;
      END IF;

I added that comment at the end. So what you've posted won't compile.

It doesn't do any inserts at all.

The only updates it does is on timeout.

There is no attempt in the code you've posted to try and do the things you say it should be doing.

You need to start again.

You need to post the full correct code you currently have.

You need to post the full correct code for the ref cursor you are calling as well.

You need to post create table and insert scripts that are relevant to the problem and actually work.

You need to describe in detail what you want the code to do.

You need to describe in detail what the code is currently doing wrong.

You need to pay attention to whether or not what you post actually makes any sense.
