Hi,
I need a PL/SQL code for this one...
Let me know if something is not clear...
1) The table CLOB_CLOBJECT_CDA has the columns described below...
Explaining only those fields which are important in this context
-- CDA_STEP_ID : Basically a Sequence
-- CLOBJECT_SOURCE1_ID : Every id has got a set of records
-- CLOBJECT_SOURCE2_ID : Every id has got a set of records
-- LVL : There are total 8 levels..
This is the main aim :
1) There are total 16 million rows..(limited to 10 rows here)
2) We need to go through level by level (LVL column) & insert the intersection records (CLOBJECT_SOURCE1_ID intersect CLOBJECT_SOURCE2_ID)
into another table...but this is how it goes..
Level (LVL column) 3's basically have CLOBJECT_SOURCE1_ID as level (LVL column) 2 CDA_STEP_ID's..
(consider the statement --** where CLOBJECT_SOURCE1_ID = 285 which is same as 1st insert statement step id)..
The above process goes for next levels until 8..(so have to use loops)
So for ex :
We go through the first insert statement and insert the insertion records only when both CLOBJECT_SOURCE1_ID & CLOBJECT_SOURCE2_ID has got records ..
If we don't find any records for both of them we should skip the corresponding step id when we go to the next levels...
Let's go through the 1st insert statement...
-- We have CDA_STEP_ID = 285 & two sources CLOBJECT_SOURCE1_ID as 19 & CLOBJECT_SOURCE2_ID as 74...
-- We see the table CLOBJECT_COUNTS & check whether we have counts for both 19 & 74 ..(In fact we insert counts into this table only if they have records)
-- If so, we insert the intersection records into CDA_MRN_RESULTS ( we do have counts for both of them..) with CDA_STEP_ID 285...
-- Then we insert the step id which is 285 along with the count into CLOBJECT_COUNTS..
Let's go through another insert statement...
-- Consider CDA_STEP_ID = 288 which has two sources CLOBJECT_SOURCE1_ID as 19 & CLOBJECT_SOURCE2_ID as 92...
-- We see the table CLOBJECT_COUNTS & check whether we have counts for both 19 & 92 ..(we have records for 19 but not for 92)
-- So we should not proceed with this..& also skip all those records (future records with increasing levels..basically level 3's) which have got 288 as CLOBJECT_SOURCE1_ID..
(As said earlier that the present CDA_STEP_ID will always be CLOBJECT_SOURCE1_ID in the next level)...
I wrote the following code which is after the statement...
Let me have the create & insert statements here..

How to add a custom PL/SQL code for a button event handler
Hi All,
I am a toddler in using Oracle Portal. So please forgive me for my ignorance.
Q : How do I add a custom PL/SQL code for a button event handler?
Basically, I would like to write MY PL/SQL function and call it. I could see that we can write "CUSTOM" code as "PL/SQL button event handler" in the form design window. But the question is that it expects only a "call" to procedure. But where do I define the procedure then? If I insert the procedure from the backend, it gets flushed the next time I compile my form.
Hope I am able to explain my point.
Thanks in advance,

Can I have a PL/SQL code for LOV
Hi,
I apologize for this dumb question. I have been so out of touch with dev (almost 8 years). Plus new to pl/sql.
I am creating a status report application. On the dashboard, I currently have some metrics (horizontal charts). I wanted to expose these metrics based on filter.
I had created 2 filters. The first one will identify the type (Week, Month, Qtr or Year) and the 2nd filter would be based on the type. For e.g. if I select Month as type, the 2nd filter should show May-12, April-12 etc. Once I select the 2nd filter, I should use them to show the appropriate metrics. The metric that I currently have would show all the projects that users have worked on during the week/month/qtr or year (depending on the 1st and 2nd filter).
On the dashboard region, I added a condition to check if the value for both 1st and 2nd filter is not null. This allows me to show the dashboard only if the 2 filters have been selected.
For the 2nd filter, I need to write a PL/SQL code to show the LOV.
I am assuming that the pl/sql would return a SQL query. The SQL query will be based on week, month etc. Is that right?
Thanks

Any help to overcome the problem?
ThanksHi,
It looks like that you must be trying to set the result of the query to some variable from the Execute SQL Task. If yes, make sure that the target variable is of the correct data type where XML string can fit into. Considering that in SSIS, we have
some limit for XML strings.
Please let me know if it doesn't help.
Thanks,

Sql code for authorizing senior staff after data was inserted in the table
Dear sirs/madams,
Sub:
I am using oracle9i/forms6i/reports6i and developing software for rural bank,
I need sql/procedure/function code for authorizing senior staff after data was inserted in to the table by the junior staff.
Thanks in advance for your kind help.
R. Chandrasekar
e-mail: [email protected]So basically you want a form (only accessible by senior staff) which reads the data entered by junior staff and when it is has been validated by senior staff
does the following in one transaction:
This is in effect a design question.
There are two different scenarios I see. Approve transactions in bulk, or approve individual transcations.
Approve transactions in Bulk:
Mark a column with approved.
Move all approved into final table;
delete all transactions from temp_table which are in final_table;
commit;
approve/move individually.
insert transcation x into final_table where transaction_x in temp_table;
delete transaction_x from temp_table;
commit;
Its basically up to you how you design it. -
How to handle SQL code for Daylight Savings for MST Time zone
Hi,
1. My time zone is MST. My data showing differently as day light saving started from November. Please help me how to handle these issue.
2. After Mar 09 2014 Daylight saving going to end.( For this how to handle in the SQL codes)
Please answer for the above 2 doubts.
Thanks in advance.
Regards,
LuckyAbdulHi Abdul,
Daylight saving is basically like switching to another timezone. If your normal time zone is Mountain Standard Time (MST), you will switch to Mountain Daylight Time in the summer.
If daylight saving or timezones are a concern. It is best to store your dates in a DATETIMEOFFSET(0) column. This data type includes the offset between your selected timezone (MST or MDT) and UTC. The offset between MST and UTC is -7 hours and the offset
between MDT and UTC is -6 hours.
Be sure to datetimeoffset(0) and not just datetimeoffset. datetimeoffset(0) uses 8 bytes to store it's data (same as datetime), but datetimeoffset uses 10 bytes. This is especially important if you are going to index this column.
Also be sure to use a similar data type in your application or the timezone information will be lost. If it is an .Net application you should use The DateTimeOffset type. Most other programming languages have equivalent types.
Hope this helps. If you have anymore questions please let me know.

Need SQL code for this logic - - From Serial and To serial no.
In Forms 4.5 Screen I have two text boxes where i will be entering From Serial No
and to serial no.
I want the code which will check whether any number in between these from and to serial exists in a table or not ?
For Example
Select * from t; -- contains
serial number
321-456-789
123-456-654
321-569-986
321-569-987
When I enter from Serial no 321-456-789 and to serial no as 321-456-789.. I should get a message sayinig that 321-456-789 exists.
When I enter from Serial no 321-569-986 and to serial no as 321-569-988.
I should get a message sayinig that 321-456-986 exists.
I should get a message sayinig that 321-456-987 exists.
I should get a message sayinig that 321-456-988 not exists.
is it possible with a SQL query or do we need to go for procedure or temp table ?
If anybody ahving similar code please post it here.

From your link it shows you're using Form Builder as your development tool.
Therefore your question belongs to the Forms Forum @ Forms and not so much in this forum.
Keep in mind to read the FAQ's you'll stumble upon in several forums, so you know what to post and what not to post.
For example, here's the SQL and PL/SQL FAQ:
Re: 3. How to improve the performance of my query? / My query is running slow.
but it didn't workThat;s something you should not post.
Be more specific.
If you get an error message, then post the exact error code and message.
Always mention your database version and your Forms version (if Forms is involved). -
Using FIFO as sql code for assigning indicator to data items
Hi All,
We are looking for a solution based on FIFO algorithm. We have a table having following data:
We need to perform FIFO on this table, and assign "object" as data items to other rows based on following conditions:
1. first we have to group the rows based on "object" column
2. then we have to traverse each group from the row having minimum start time of the object group e.g: row id 1 for object group for "19O"
2.1 Assign a "EqpREf" as "object" + <an integer value> , where integer value changes when the start and end chain finishes. Start -end chain is explained in step 2.2
2.2 then we have to pick the "nextstarttime" of the picked row and compare it against the closest "starttime" of the rows having "start" as same as "end" of the same row we are
picking for "nextstarttime" e.g: row id 2 of object 19O is having "nextstarttime" 0310 closest to "starttime" 0355 of row id 2 of object 19O , and rowid 2 is having "start" AAL which is similar to "end" of
rowid 1
2.3 We have to perform this chain till we find end of same and allocate each row in a chain same "Eqpref"
hence the output we need to generate will come as:

What we are doing here is generating a schedule for Trains departures.
here, we should identify the train schedules making a chain of stations considering the endstation of a train engine no should be startstation of another record for same engineno. also the starttime of engineno should be nearest of nextstarttime
of same station.
for example : if we pick Ist row "SGC-IXP", nextstarttime for same is "02:00:00 am". this means train departed from SGC will reach to IXP and is available for departure from IXP after "02:00:00 am". So we have to consider
the record having startstation as IXP and nearest starttime to nextstarttime ("02:00:00"). So the next train departure would be IXP-DFW having starttime as "03:30:00 am".
here you can see we have to assign the scheduleno of previously considered record to the chained schedule so we have updated the "schedule_ref" as 101. Also we have to assign the engine no - <counter of integer> to a single chain on schedule
given in engine_ref.

How to write the pl/sql code for this scenario
Hi,
Here is the data in a Table with below colums
id firstname lastname code
1 scott higgins 001
2 Mike Ferrari 001
3 Tom scottsdale 002
4 Nick pasquale 003
1 scott higgins 004
I want to trap the following exceptions into an error table using pl/sql
1. same person having multiple code
example
id first last Code
1 scott higgins 001
1 scott higgins 004
2. Multiple persons having same code
id first last Code
1 scott higgins 001
2 Mike Ferrari 001
Could you please help me how to capture the exceptions above using pl/sql
and what will be the structure of error table. it should capture eff date & end dateor using analytic functions like this:
select id, fname, lname, code from (
with t as(
select 1 id, 'scott' fname, 'higgins' lname, 001 code from dual
union all
select 2 id,'Mike ' fname, 'Ferrari' lname, 001 code from dual
union all
select 3 id,'Tom' fname, 'scottsdale' lname, 002 code from dual
union all
select 4 id,'Nick' fname, 'pasquale' lname, 003 code from dual
union all
select 5 id,'scott' fname, 'higgins' lname, 004 code from dual
select t.*, count(*) over (partition by fname) row_count from t)
where row_count > 1;
select id, fname, lname, code from (
with t as(
select 1 id, 'scott' fname, 'higgins' lname, 001 code from dual
union all
select 2 id,'Mike ' fname, 'Ferrari' lname, 001 code from dual
union all
select 3 id,'Tom' fname, 'scottsdale' lname, 002 code from dual
union all
select 4 id,'Nick' fname, 'pasquale' lname, 003 code from dual
union all
select 5 id,'scott' fname, 'higgins' lname, 004 code from dual

Newbie trying to analyze code for xml tags
My problem is that I need to find what xml tags my java files contain. Is there a way to run a search and pull out all xml tags? Thank you.
you mean you have to find xml tags in .java file. you have to write a program that will read the contents of file and then check for any string that contains < and ends with >. U can use LineNumberReader class for reading a line. besides these u have to take care of comments.
Regards,
Gurpreet
