SQL Query of an OWB map (row based)

If I trace a session, execute an OWB map (row based), will the trace file contain the actual SQL query ?
The problem with me is that when I am executing this row -based OWB map, it is throwing me an error CursorFetchMapTerminationRTV20007 BUT ( plus taking a long time) when I am taking out the intermediate SQL insert query,it is working fine ( and also within a very short period of time)
Execution status = COMPLETE
message text = ORA-06502: PL/SQL: numeric or value error: character string buffer too small
message text = CursorFetchMapTerminationRTV20007
No. task errors = 0
No. task warnings = 2
No. errors = 1
Since this OWB map (Truncate Insert) is row based hence I cannot cannot get the back end query from the OWB generated pl/sql package so wondering if I trace the session, check the trace file, may be I will able to see the exact SQL query generated. But wanted to confirm the same.

Yes, the actual SQL run in the session will be in the trace file.

Exists (SQL query returns at least one row) condition with MAX on 10.2.0.4

I just wanted to note this on the forum..
I'm using Apex 3.0.1.00.08
My DEV environment has just been upgraded from 10g version 10.2.0.2.0 to 10.2.0.4.0.
I created the following process to select some values into some items on my Form page.
select MAX(STAT_YEAR+1)
      , pcd.pct_id
      , pcd.stat_type_id
      , pcd.stat_period_type_id
      , pcd.measurement_id
into    :P11_STAT_YEAR
      , :P11_PCT_ID
      , :P11_STAT_TYPE_ID
      , :P11_STAT_PERIOD_TYPE_ID
      , :P11_MEASUREMENT_ID
from plant_commodity_data pcd
    , stat_type stt
where pcd.STAT_TYPE_ID = stt.STAT_TYPE_ID
and pcd.pct_id = :P0_PCT_ID
and stt.stat_type = 'PRD'
group by pcd.pct_id
      , pcd.stat_type_id
      , pcd.stat_period_type_id
      , pcd.measurement_id;The process should run conditionally if there was at least one row to select...
So I copied the SQL into the Process condition, removed the "into" section and set the condition type to be "Exists (SQL query retruns at least one row) ...
select MAX(STAT_YEAR+1)
      , pcd.pct_id
      , pcd.stat_type_id
      , pcd.stat_period_type_id

from plant_commodity_data pcd
    , stat_type stt
where pcd.STAT_TYPE_ID = stt.STAT_TYPE_ID
and pcd.pct_id = :P0_PCT_ID
and stt.stat_type = 'PRD'
group by pcd.pct_id
      , pcd.stat_type_id
      , pcd.stat_period_type_id
      , pcd.measurement_id;This worked perfectly until the DEV environment was upgraded from 10g version 10.2.0.2.0 to 10.2.0.4.0.
The condition would fire even if there were no rows returning.
I pasted the condition code into SQL Developer connected to the DEV (10.2.0.4.0) environment and it returned no rows.
To solve the problem, I removed the MAX.
You can test this using this code if you have access to the two versions... select MAX(1)
      , sysdate
      , 'Gus'
from dual
where 1 = 2
group by sysdate, 2Now I know the MAX isn't required in the condition as I'm just trying to find out if any rows exist, but it was there as I copied the code in... I was just wondering why this happened between 10.2.0.2.0 and 10.2.0.4.0?
Gus..

Hi Gus,
try to execute
select count(*) from dual where exists (select MAX(1)
      , sysdate
      , 'Gus'
from dual
where 1 = 2
group by sysdate, 2)in SQL Developer. The above statement is generated by APEX for an "Exists (SQL query retruns at least one row)". Can't test it, because I don't have a 10.2.0.4.0 at hand.
Does SQL Developer now show the same behavior?

SQL Query (PL/SQL Function Body returning SQL query) doesn't return any row

I have a region with the following type:
SQL Query (PL/SQL Function Body returning SQL query).
In a search screen the users can enter different numbers, separated by an ENTER.
I want to check these numbers by replacing the ENTER, which is CHR(13) || CHR(10) I believe, with commas. And then I can use it like this: POD IN (<<text>>).
It's something like this:
If (:P30_POD Is Not Null) Then
v_where := v_where || v_condition || 'POD IN (''''''''||REPLACE(''' || :P30_POD || ''', CHR(13) || CHR(10), '','')||'''''''''')';
v_condition := ' AND ';
End If;
But the query doesn't return any rows.
I tried to reproduce it in Toad:
select * from asx_worklistitem
where
POD IN (''''||REPLACE('541449200000171813'||CHR(13) || CHR(10)||'541449206006341366', CHR(13) || CHR(10), ''',''')||'''')
==> This is the query that does't return any rows
select (''''||REPLACE('541449200000171813'||CHR(13) || CHR(10)||'541449206006341366', CHR(13) || CHR(10), ''',''')||'''')
from dual;
==> This returns '541449200000171813','541449206006341366'
select * from asx_worklistitem
where pod in ('541449200000171813','541449206006341366');
==> and when I copy/paste this in the above query, it does return my rows.
So why does my first query doesn't work?
Doe anyone have any idea?
Kind regards,
Geert

Thanks for the help.
I made it work, but via the following code:
If (:P30_POD Is Not Null) Then
v_pods := REPLACE(:P30_POD, CHR(13) || CHR(10));
v_where := v_where || v_condition || 'POD IN (';
v_counter := 1;
WHILE (v_counter < LENGTH(v_pods)) LOOP
v_pod := SUBSTR(v_pods, v_counter, 18);
IF (v_counter <> 1) THEN
v_where := v_where || ',';
END IF;
v_where := v_where || '''' || v_pod || '''';
v_counter := v_counter + 18;
END LOOP;
v_where := v_where || ')';
v_condition := ' AND ';
End If;But now I want to make an update of all the records that correspond to this search criteria. I can give in a status via a dropdownlist and that I want to update all the records that correspond to one of these POD's with that status.
For a region you can build an SQL query via PL/SQL, but for a process you only have a PL/SQL block. Is the only way to update all these records by making a loop and make an update for every POD that is specified.
Because I think this will have a lot of overhead.
I would like to make something like a multi row update in an updateable report, but I want to specify the status from somewhere else. Is this possible?

SQL query to fetch approximately 9000 rows

Hi,
I am using the following SQL query in a java class. Using JDBC to connect to an Oracle database using JRUN app server connection pooling.
SELECT PT.ACCOUNT_NUMBER,PAYMENT_REF_ID, TO_CHAR (PT.DATE_CREATED, 'MM/DD/YYYY'),
PT.AMOUNT_PAID, DECODE(STATUS_VALUE,'Cancelled','Canceled',STATUS_VALUE)
FROM EPAY_PAYMENT_TRANSACTIONS PT, EPAY_STATUS_LOOKUP SL
WHERE
PT.CLIENT_NAME = 'someclientname'
AND TO_CHAR(DATE_PAYMENT_SCHEDULED,'MM/DD/YYYY') = '08/28/2006'
AND PT.PAYMENT_STATUS = SL.STATUS_CODE
ORDER BY PT.DATE_CREATED DESC
EPAY_PAYMENT_TRANSACTIONS is a huge table consisting of thousands of rows. There are 4 indexes defined on this table but not on the columns used in the join condition of the query.
EPAY_STATUS_LOOKUP is a much smaller table mainly used for lookup consisting of some 100 rows.
The above query fetches approx 9000 records and takes a very long time to execute. Is there any way it can be optimized or we can change some attributes on the tables involved for speeding up the query?
Thanks in advance,
Nisha.

So the task is to avoid FTS on EPAY_PAYMENT_TRANSACTIONSWell, maybe...
But I believe that we have yet to hear more details about data distribution, execution plans and so on.
Because it all depends...

It all depends on underlying data distribution. That's why I asked user527580 to tell us more.

SQL Query to retrieve the All records based on the Max Dates.

Hello all,
I am trying to retrieve the newest record based on the date field ( nextDate ).
Currently there are only 4 records in the MC_Maintenance table and two in the Machine table.
Machine table
MC_id             EquipID
1                     0227
MC_id             EquipID
2                     0228
MC_Maintenance table
Maint_id           MC_id             Next_maint
1                      2                      08/25/2010
2                      2                      07/01/2010
3                      1                      06/11/2010
4                      1                      07/11/2010
What I am trying to accomplish is,
list the two machines from the Machine table with the MAX(Next_maint) controlling the MC_Maintenance output list
These are the records that I would like to Display.
Maint_id           MC_id             Next_maint
1                      2                      08/25/2010
4                      1                      07/11/2010
Below is the SQL Query
SELECT
       MC.MC_ID as ID,
        MC.complete_Date as completed,
        MC.next_maint as nextDate,
        MC.maint_notes as Notes,
        MC.facility as Facility,
        M.EquipId,
        M.name as name,
        M.SerialNumber as SN,
        M.dept as dept,
        M.Freq as freq
        From MC_Maintenance MC, Machine M
        where MC.MC_ID = M.MC_ID
'           USING MAX(nextDate )
Any ideas would help.
TJ

I would have thought that was a simple group by problem?
SELECT M.EquipID, MC.MC_ID, Max(MC.next_maint)
FROM MC_Maintenance MC INNER JOIN Machine M ON MC.MC_ID = M.MC_ID
GROUP BY M.EquipID, MC.MC_ID

Your requiremnt is more of a reporting request which should not be handled in SQL. For example in SQL Plus you can use the BREAK command
SQL> break on deptno
SQL> select deptno, ename from emp order by deptno;
    DEPTNO ENAME
        10 KING
           CLARK
        20 JONES

        30 TURNER
           MARTIN
           WARD
           ALLEN
           BLAKE
11 rows selected.
SQL>
But if you still wish to do it in SQL you can use ROW_NUMBER analytic function and achieve it like this
select decode(rno, 1, deptno) deptno
     , ename
from (
          select row_number() over(partition by deptno order by ename) rno
               , deptno
               , ename
            from emp

Howto: SQL query to obtain latest n rows

Hey everyone,
I want to query a subset of a table to return, at most, a certain number of rows. The problem is that 'rowcnt' is not going to be good enough. Here's the situation:
I have a table with lots of data (15 days worth). It will accumulate over time, but I want to extract, say, only the last 10 rows that were placed into the table. That would be simple, but there is one other catch, there is a key column and I may want to select rows from each "key". So a simple row count won't work :(.
Here's a sample table:
key         varchar(10)
val1        varchar(5)
val2        varchar(5)
epoch_time number(30)Now, this would ALMOST work:
select key, val1, val2, epoch_time from t where key='KEYVAL1' and rowcnt <= 10 order by epoch_time desc;
Because the decending sort on epoch_time guarentees that the latest 10 rows will be returned. The problem arises when I want this:
select key, val1, val2, epoch_time from t where key IN ('KEYVAL1', 'KEYVAL2') and rowcnt <= 10 order by epoch_time desc;
I intend to get 10 rows (or less) returned for each 'KEYVAL1' and 'KEYVAL2', but since rowcnt is a global count of rows returned this obviously won't work as desired.
Keep in mind that I could have 5 rows, 10 rows, 1000 rows for a key...so I could be selecting three keys, one with 5 rows, the next with 40 and the next with 7. Therefore, if I did something like assume I'll get back 30 rows (10 per key) this situtation would render that solution invalid because I'd get 5 from the first and 25 from the second and none from the 3rd.
So, the actual question is, can I make some modification to the above query such that I can get the last 10 rows from both 'KEYVAL1' and 'KEYVAL2'. Possibly changing the order by clause to order by both key and epoch_time and then somehow switching the rowcnt to a value that would be capable of returning itself to 0 upon encountering a new key value?? I think I could do this with PL/SQL, but I'd have to use a static value to hold the row count and last passed key value, and that wouldn't work if more than one query executed at once unless there were some kind of "query specific data" (analogous to thread specific data) that I could utilize.
If not, I guess I'll have to write a PL/SQL routine to simulate the entire query because I can't use unions (at least I don't think I can) because I have to be capable of using an IN list to determine the key values I desire.
If anyone has a suggestion, I'd really appreciate it. THANKS!

Are you running with 8.1.6 Enterprise Edition or higher? If so, you can solve your problem with Analytic functions, specifically RANK() or DENSE_RANK().
SELECT * FROM
( SELECT key, val1, val2, epoch_time,
       DENSE_RANK() OVER (PARTITION BY key ORDER BY epoch_time DESC) AS ep_rank
FROM   t
WHERE key IN ('KEYVAL1', 'KEYVAL2')
) WHERE ep_rank <= 10;Caveat: this code is typed without benefit of database so you may need to check the syntax.

SQL Query does not have all rows in ResultSet

I am using JDK 1.4.2 and an MS Access 2000 database where I attempt to retrieve data and I get in the ResultSet a maximum of around 280 rows, but there are more that seem to be ignored. In Access I can see them using the same query.
The Statement.getMaxRows() returns 0 and I do not understand why I do not get the other ones. The query is issued using Statement.executeQuery(String), but using execute() does not make a difference, There is just one ResultSet returned.
I would appreciate your help.

I had this same problem once because in my Java code I was connecting to our alpha database and when I was running the query manually I was connecting to our production database.
The only other thing I can think of that might cause this is if on the 281st row there is something wrong with the row and maybe the SQLException isn't being processed? Can't really say without seeing your code, but if you don't have a printStackTrace() or some indicator when a SQLExcpetion is thrown it could be breaking without your knowing. If those aren't the problems maybe you could post your code.

SQL query results. more than 10 rows

Home>SQL>SQL Commands
Results tab says
More than 10 rows available. Increase rows selector to view more rows.
How can I "Increase rows selector to view more rows."?

Sim,
above the text area for the sql command you find a combobox with the label "Display". Initially only 10 records will be displayed.

OWB use unwanted RTRIM in generated row based code

Hi everybody,
In a pretty straightforward mapping with simple DELETE and then INSERT OWB generate row based code. This would not bother me too much but in INSERT statement OWB use TRIM for all character columns immediately converting fields with spaces into NULL which I badly need to avoid. Does anybody know if this is OWB feature or is it configurable and can be avoided?
I would appreciate any suggestions,
Alex

There are more than one way you can do this. Put it in the pre-mapping process, as described by you, use an expression, use a trasformation or use a temporary table to store constant values calculated on the fly. It all depends on what exacltly you want to do and on your environment details.

Regarding SQL query in OWB

Pls advice how can we use free hand sql query in an OWB job?
There must be a way other than mapping src tables and joiner , aggregator to target table. How to implement SQL sub-queries in OWB?
-Kuntala

OWB is all about creating a mechanical process that works fast, so you wouldn't really expect to enter ad hoc queries. What is the purpose of the project, and what problem is the freehand query meant to solve?

SQL Query updateable report with row selector. Update process.

I have a SQL Query updateable report with the row selector(s).
How would I identify the row selector in an update process on the page.
I would like to update certain columns to a value of a select box on the page.
Using the basic:
UPDATE table_name
SET column1=value
WHERE some_column=some_value
I would need to do:
UPDATE table_name
SET column1= :P1_select
WHERE [row selector] = ?
Now sure how to identify the [row selector] and/or validate it is checked.
Thanks,
Bob

I don't have the apex_application.g_f01(i) referenced in the page source...In the page source you wouldn't find anything by that name
Identify the tabular form's checkbox column in the page(firebug/chrome developer panel makes this easy)
It should be like
<input id="..." value="" type="checkbox" name="fXX" >we are interested in the name attribute , get that number (between 01 and 50)
Replace that number in the code, for instance if it was f05 , the code would use
apex_application.g_f05
--i'th checked record' primary keyWhen you loop through a checkbox array, it only contains the rows which are checked and it is common practice to returns the record's primary key as the value of the checkbox(available as the the i'th array index as apex_application.g_f05(i) , where i is sequence position of the checked row) so that you can identify the record.

SQL query rows 5 to 10

I ran into a problem which i cant figure out, i wand to write
a SQL query which will give me rows 5 - 10 as output.
So far i only get first row to last or limit it to 5 but i
cant tell it i want rows 5, 6, 7, 8, 9, 10. Basicly minus the first
5, in the DB are 100 entries. anyone know how that would look like.
or has a tutorial or something for me to read.

This should give you all the rows minus the first 5 in the
table:
SELECT * FROM YourTable
WHERE TheID NOT IN
SELECT TOP 5 TheID
FROM YourTable
