To find missing sequence numbers in a table

Hi ,
I populate the primary key column of a table using sequence which starts with 1 and increments by 1. I need to find the sequence numbers which have been skipped while inserting.

Hi,
Please refere the similar thread.

Finding missed sequence numbers and rows from a fact table

Finding missed sequence numbers and rows from a fact table
Hi
I am working on an OLAP date cube with the following schema:
As you can see there is a fact transaction with two dimensions called cardNumber and Sequence. Card dimension contains about three million card numbers.
Sequence dimension contains a sequence number from 0 to 255. Fact transaction contains about 400 million transactions of those cards.
Each transaction has a sequence number in 0 to 255 ranges. If sequence number of transactions of a card reaches to 255 the next transaction would get 0 as a sequence number.
For example if a card has 1000 transactions then sequence numbers are as follows;
Transaction 1 to transaction 256 with sequences from 0 to 255
Transaction 257 to transaction 512 with sequences from 0 to 255
Transaction 513 to transaction 768 with sequences from 0 to 255
Transaction 769 to transaction 1000 with sequences from 0 to 231
The problem is that:
Sometimes there are several missed transactions. For example instead of sequence from 0 to 255, sequences are from 0 to 150 and then from 160 to 255. Here 10 transactions have been missed.
How can I find all missed transactions of all cards with a MDX QUERY?
I really appreciate for helps

Thank you Liao
I need to find missed numbers, In this scenario I want the query to tell the missed numbers are: 151,152,153,154,155,156,157,158,159
Relative transactions are also missed, so I think it is impossible to get them by your MDX query
Suppose this:
date
time
sequence
20140701
23:22:00
149
20140701
23:44:00
150
20140702
8:30:00
160
20140702
9:30:00
161
20140702
11:30:00
162
20140702
11:45:00
163
As you can see the sequence number of the last transaction at the 20140701 is 150
We expecting that the first transaction of the next day should be 151 but it is 160. Those 10 transactions are totally missed and we just need to

Finding missing sequence

Hello all.
I'm using the Oracle 10g Database. i'm trying to figure out how to write a simple sql query to:
find the missing numbers in a table between say 86002895 and 86005197 (inclusive)
Ex: Current Scenario : table_1 :
tracking_no | id_value
86002895 | 10
86002896 | 10
86002899 | 10
86002900 | 10
86002910 | 10
86005196 | 10
86005197 | 10
Expected Result1:
" missing tracking_id " where id_value = 10 from table_1 ;
86002897
86002898
86002900 to 86002910
86002910 to 86005196
Thanks in advance :)

FInding missing sequence number

Dear All
I have a column in table like this (actually its just a sample):
TAB
MMxxxx9988
MMxxxx9990
MMxxxx9995
MMxxxx9998
MMxxxx9999
MMxxxx0000
MMxxxx0001
MMxxxx0003
MMxxxx0004
MMxxxx0005
MMxxxx0008
xxxx is variable
last four digit is a sequence number start with 0000 and end with 9999.
when the last four digit exceeds 9999 it reset to 0000
My question is : how can we find the missing sequence number for that column.
example:
for the above table , it should give the below result:
TAB
MMxxxx9989
MMxxxx9991
MMxxxx9992
MMxxxx9993
MMxxxx9994
MMxxxx9996
MMxxxx9997
MMxxxx0002
MMxxxx0006
MMxxxx0007

How do I find missing entries in outer join table?

Hi all,
I am trying to find records in table1 that are missing in table2. This is a simple process in SQL, but ABAP is giving me trouble. I want to do this using an outer join.
Example:
Select table1~docnumber
From table1
Left Outer Join table2
On table1docnumber = table2docnumber
Where table2~docnumber IS NULL. (the record is missing in table2)
Note: ABAP gives an error and wants me to use the Having Clause, which is ok, but then ABAP wants me to use Group By, which ok, but then I still get the same syntex error.
Any thoughts on doing this with the outer join and is null options. I do not want to select into two internal tables and compare them.

All,
I am not trying to do a subquery. Just a simple outer join where I know some records are missing in the second table.
Here is the code:
select eban~banfn
into table i_delay_banfn
from eban
left outer join zsmt_prdelay_upd
on eban~banfn = zsmt_prdelay_upd~banfn
where zsmt_prdelay_upd~banfn IS NULL.
Here is the error message:
No fields from the right-hand table of a LEFT OUTER JOIN may appear in
the WHERE condition: "ZSMT_PRDELAY_UPD~BANFN".
select eban~banfn
into table i_delay_banfn
from eban
left outer join zsmt_prdelay_upd
on eban~banfn = zsmt_prdelay_upd~banfn
having zsmt_prdelay_upd~banfn IS NULL.
Please use code tags

Find/Change Item Numbers and create Table of Contents

Hello! I need help to find all my item numbers and apply a paragraph style to it so I can use them to create a Table of Contents page.
Sample item numbers
#12345
#12345-5
#12345-20
#12345-ABC
#12345/N
I tried entering #^?^?^?^?^? on the Find/Change box and but this will find exactly the 5 characters after the # sign. I wonder if you can find all characters starting with # and until the last characters.
Once I find all the item numbers, how can I apply the paragraph style for only those characters after the # sign? Because I only want to show the item numbers without the # sign on the Table of contents/Index page.
By the way, I have InDesign CS2 which have no GREP function Maybe I can do this without the GREP?
I really appreciate any help. Thank you very much.

You actually have two problems here. The first is to assign the paragraph style. For that you can use GREP.
Find #\d+ and leave the change field blank, but in the change formatting pick the paragraph style. Stricly speaking you only need to find #\d or even just # because a paragraph style applies to an entire paragraph, so assigning it to any character inthe paragraph will assign it to the entire paragraph.
Which is your second problem. The TOC is based on paragraph styles and will include all of the text in each paragraph (up to the character limit for a TOC entry, which I think is 256 characters). You can't make a TOC and only use some of the paragraph. For that you need to use an index, or you need to make hidden or non-pinting frames with only the exact text you want in the TOC and assign a unique style to those.
It's also possible someone has written (or could write) a script that can find text strings that match a pattern such as your numers, assign a character style to them (you could actually do that part in the paragraph style by adding a nested GREP style), then making a list of the text strings along with the page number on which they appear -- almost the same as an index except it would be based on character style, not an index marker.

Find Missing sequence in Alphabet

Two table records.
(Table1) Holds values A,B,C,D,E,F....Z, AA,AB,AC,AD..e.t.c
(Table2) Holds values A,C,D,E,F.....Z,AA,AC,AD e.t.c
I need to compare the two tables and findout if they are in Alphabetical sequence, if any sequence is missing I need to write out to a table.
(Table1) Has A,B,C
(Table2) Has A,C,D So B is missing and also AB is missing.
How do I get this accomplished in my PL/SQL

The easiest to check whether things are missing is with the MINUS operator...
SELECT 'in a not b', col1 FROM table_a
MINUS
SELECT 'in a not b', cola FROM table_b
UNION ALL
SELECT 'in b not a', cola FROM table_b
MINUS
SELECT 'in b not a', col1 FROM table_a As for whether they are in alphabetical order, the only way of guaranteeing the order of rows in a table is with an ORDER BY when we select them. Note that with an alaphabetical sort AB comes before B. But if that's not what you mean by alphabetical order help is at hand...
SQL> create table abcd (cola varchar2(3));
Table created.
SQL> insert into abcd values ('A');
1 row created.
SQL> insert into abcd values ('B');
1 row created.
SQL> insert into abcd values ('C');
1 row created.
SQL> insert into abcd values ('AB');
1 row created.

How to find PRPS missed object numbers ?

Hi Frds,
While checking PRPS object numbers some object numbers are missed in the table.
How will you find that object numbers deleted or changed?.Kindly anyone can suggest for finding missed object numbers.
Thanks for your advance help.
Regards,
Nivas.

Hi,
Note the following.
1. If WBS element was deleted by using icon Trash can, it is not possible to see the element in PRPS table. This action deletes elements permanently and hence and not traceable at table level.
2. If WBS element was set to DLFL (deletion flag), we can see delete indicator at table level.
3. You can do small test in your system, change the settings to "display deleted objects", if objects showing with deletion flag means these are available in system but temporarily set to DLFL and can be retrievable back into project structure. For those objects only you can see X indicator at Table level.
In your case some one might have deleted permanents and hence not showing.
Thanks,
Sudhakar

Recycled Sequence Numbers

Hi,
We have a requirement of generating sequence numbers for a table and we need to recycle them if some of them is deleted.
For example the following tabe Employee(Id,name)
ID NAME
1 XXX
2 YYY
3 ZZZ
4 AAA
The ID filed should have the next sequence number generated. When I call getnextID now, it should return 5
ID NAME
1 XXX
2 YYY
3 ZZZ
4 AAA
5 BBB
Now Let us assume I delete 3. The contents of the table aare
ID NAME
1 XXX
2 YYY
4 AAA
5 BBB
Now when getNextID, 3 should be returned.
How to achieve this in a best performing way in Oracle? Are there any patterns around it? Please note this should run in a multi user environment.
Thanks,
Rama

I think the answers were based on the fact that you call it incorrectly sequence.
Your ConnectivityID is more as a resource that could be recycled. I see some similarities to the GSM telecom market where a resource(i.e. a phone number or a SIM card no) can be recycled when is not active anymore (under certain conditions however).
Personally I would generate a table of resources having the resource number (ConnectivityID) and resource status.
To simplify it, suppose that you have column status with 2 possible values, 0=available, 1=not available.
When you want to allocate the resource number(ConnectivityId) you will set the status to 1.
When the record is deleted then status will be updated back to 0.
Recycling a ConnectivityID will mean searching in the table for the lowest number having status=0.
Of course you don't expect this to be as fast as a sequence but I think this is a different requirement, IMO.

Assigning sequence numbers treo cords

Please help to understand the following, because it's a little unclear for me.. can you provide me an example?
So, regarding to assigning sequence numbers when a new record is created, we usually use a pre-insert trigger, with this code:
SELECT orders_seq.NEXTVAL
INTO :orders.order_id
FROM SYS.dual;
But:
You can also assign sequence numbers from a table. If you use this method, two transactional
triggers are usually involved:
• Use Pre-Insert to select the next available number from the sequence table (locking the row
to prevent other users from selecting the same value), assign it to the Forms item, and
increment the value in the sequence table by the required amount.
• Use Post-Insert to update the sequence table, recording the new upper value for the
sequence.So how to assign a sequence number from a ... table?
Thanks

You have to implement the number generator yourself; something similar to this: http://asktom.oracle.com/pls/apex/f?p=100:11:0::::P11_QUESTION_ID:4343369880986

Indexing - Out of Sequence and Missing Page Numbers

I have a 296 page book. This is an on-going project and has been updated many times.
Two new sections have been added to this book. I have marked words for indexing.
My problem is that many of the page numbers are repeated or out-of-sequence.
For example: Intake Manifolds 66, 67, 68, 69, 68, 87, 68, 69, 186, 189, 203
This is one item that is not in the new sections, so this should not have changed.
I also have noticed missing page numbers. I verified a 'Helmets & Accessories' marker on page 248 of the new section, but it doesn't show up in the index at all.
Does anyone have any idea what could cause this? I have searched the net for others having the same issues, but I haven't found many.
IDCS4 on Mac Pro.
Thanks.
Randy

We are having the same problem! I'm using ID CS4 6.0.1 on a 1.8 GHz PowerPC G5 running OS X 10.5.6. For example, see below. The * represents a missing page number.
Axle, Rear
Alignment 163
Fastener Torque 15
Magnetic Drain Plugs 28, 51, 27, 45 [note how out of sequence these are!!]
Preventive Maintenance *, 145
CS3 was finally fixed by an Adobe patch, and as far as indexing big books went, became as solid as a rock. But now they have broken it again!! It is killing us, because we've switched 20 computers to CS4 only and updated all of our files, so we can't go back!
The only thing that seems to work is to find problem files and open the Index palette and click the Update Preview button. THEN you run your index, and sometimes it's fixed. A couple of "bad" files can spoil the whole barrel, but it's impossible to figure out which ones are bad, or even why they're bad. And when you finally fix one problem, by using the Update Preview button or by blowing away index markers and re-doing them, and getting rid of unused topics, the SAME PROBLEM will appear in other places related to other files in your book, that were "good" before!!!

Finding Missing Numbers

I want to find missing numbers from a column which is alpha numeric, its last five positions are numeric. At first three positions there are different combinations of alphas i.e. *'BA ','BAW','SA ','SAA' ..........* if alphas are two then 3rd position is blank. I also need it to generalised this to cover all existing alpha numeric series.
SELECT SUBSTR (a.claim_no, 4, 5) + 1

                 SELECT NULL
                   FROM core_business.cb_pensioner b
                  WHERE to_number(SUBSTR (b.claim_no, 4, 5)) = to_number(SUBSTR (a.claim_no, 4, 5)) + 1)
   order by SUBSTR (a.claim_no, 4, 5);I am getting ORA-01722 error

You have two issues with such a task.
Problem 1 is how to convert the trailing part into a number so that you can compare values.
to_number(SUBSTR (b.claim_no, 4, 5)) works, but only if the value in b.claim_no is always a number regardless of the other column criteria.
A statement like
WHERE SUBSTR (a.claim_no, 1, 3) = 'BA ' /* filter 1 */
and to_number(SUBSTR (b.claim_no, 4, 5)) > 1 /* filter 2 */
...might fail because your table might have a value like
b.claimno = 'XYZ1234b'
The way you wrote the query the database will decide which filter criteria it executes first. It might be filter1, but could also be filter2. If filter2 is executed first then you will get the error message.
Problem 2 how to order and compare different rows, so that you can find the missing values.
Here the analytic LEAD(LAG) function is very helpful. it will give you access to the next (or previous row).
Both problems can be overcome.
Here is my try, but I'm not sure if it works in your case. You might need to adapt a little.
This should work if all the rows are numeric that belong to the specific groups. if you can have wrong data in there too, then a different approach is needed.
with testdata as (select 'XYZ1234b' claim_no from dual union all
            select 'BA 12345' claim_no from dual union all
            select 'BA 12346' claim_no from dual union all
            select 'BA 12350' claim_no from dual union all
            select 'BAW11111' claim_no from dual union all
            select 'BAW11113' claim_no from dual union all
            select 'XYZ1234b' claim_no from dual )
/* end of test data creation */
select claim_no, substr(claim_no, 1,3) part1, substr(claim_no, 4) part2,
       to_number(substr(claim_no, 4)) current_num,
       lead(to_number(substr(claim_no, 4))) over (partition by substr(claim_no, 1,3) order by to_number(substr(claim_no, 4))) next_num,
       lead(to_number(substr(claim_no, 4))) over (partition by substr(claim_no, 1,3) order by to_number(substr(claim_no, 4)))
        - 1 - to_number(substr(claim_no, 4))
        as "missing_values"
from testdata
where substr(claim_no, 1,3) in ('BAW','BA ')
order by claim_no;
CLAIM_NO PAR PART2 CURRENT_NUM   NEXT_NUM missing_values
BA 12345 BA 12345       12345      12346              0
BA 12346 BA 12346       12346      12350              3
BA 12350 BA 12350       12350
BAW11111 BAW 11111       11111      11113              1
BAW11113 BAW 11113       11113Problem 1 is solved because the where condition is always executed before the function in the select clause, especially in connection with an analytic function.
Problem 2 is also solved by using the analytic function LEAD function. And this is fast, because you access the same table only one time. Other solution might do a subquery to fetch the value from the previous/next row. This means several accesses to the same table and is usually much slower.
