Triggers to Update rows in the same table

Hi,
I have a table called as "Cal" which has the following fields
CALID
Description
RecurringID
There will be many records with the same recurring id and If the Description field is Updated, then I would like to Update the same description to all the records with the same recurring id (same table). I have tried it with triggers and the I get the ORA-00036 Maximum number of Recursive SQL reached error.
I have a a row level trigger which captures the change and I use the statment level trigger to update the description field (same table) and I get the error mentioned above.
Thx in advance
Ravi

I have three kind of suggestion.
(1) Use session variables in a package as flag for prevention from infinitely recursive calling.
(2) Use temporary tables for similar reason.
(3) Use instead-of-trigger (need to create view).

Trigger in mutation - Update another rows in the same table with a trigger

Hi ,
I try to do a before update trigger on a table , but the trigger is in mutation. I understand why it do that but my question is :
How can I update other rows in the same table when a UPDATE is made on my table??????
Here is my trigger :

A standard disclaimer, the mutating trigger error is telling you that you really, really, really don't want to be doing this. It generally indicates a major data model problem when you find yourself in a situation where the data in one row of a table depends on the data in another row of that same table. In the vast majority of cases, you're far better off fixing the data model than in working around the problem.
If you are absolutely sure that you cannot fix the data model and must work around the problem, you'll need
- A package with a collection (or global temporary table) to store the keys that are modified
- A before statement trigger that initializes the collection
- A row-level trigger that adds the keys that were updated to the collection
- An after statement trigger that iterates over the data in the collection and updates whatever rows need to be updated.
If you're on 11g, this can be simplified somewhat by using a compound trigger with separate before statement, row-level, and after statement sections.
Obviously, though, this is a substantial increase in complexity over the single trigger you have here. That's one of the reasons that it's generally a bad idea to work around mutating table exceptions.

MULTIPLE UPDATES/INSERTIONS TO THE SAME TABLE

How can I update/insert mutiple rows into the same table from one form ?

Hi,
Using the portal form on table you can insert only a single row. You can use master-detail form to insert multiple rows.
Thanks,

SUM two ROWS in the SAME Table

Hi,
I have a problem with this issue. I want to sum two rows from the same table, but I don´t know how to do that. I tried to do it with CTE, but always I get the same error "Ambiguous". I would like to ask you, if there is other manner to get that
data (sum two rows) and if it is possible to see examples about it.
Thank you in advance

How can I align two different text row in the same table in two different way (one centered and the other one on the left)?

Hi,
I want to center two different text row that are in the same table but one on the center and the other one on the left. I put a <span> tag hoping that it has been overwhelmed the table's class properties The .bottomsel's font-family and the .Cig84's font-family and colour work but the text-align don't: they're both on the left.
These are my source and CSS codes:
Source:
<table width="600" border="0">
<tr>
    <td class="bottomref"><p><span class="bottomsel">| <a href="index.html" target="_self">Main</a> | <a href="about.html" target="_self">About</a> | <a href="clients.html" target="_self">Clients</a> | <a href="contact.html" target="_self">Contact</a> |</span><br />
      <span class="credits">Credits: <span class="Cig84">Cig84</span></span></p></td>
</tr>
</table>
CSS:
.bottomsel {
text-align: center;
font-family: Georgia, "Times New Roman", Times, serif;
.credits {
text-align: left;
.Cig84 {
color: #F00;
font-family: "Comic Sans MS", cursive;

Use paragraph tags with CSS classes.
CSS:
     .center {text-align:center}
     .left {text-align:left}
HTML:
<table width="600" border="0">
<tr>
    <td class="bottomref">
          <p class="center">This text is center aligned</p>
          <p class="left">This text is left aligned</p>
    </td>
</tr>

How do you Copy a row to create a new row in the same table?

Hi,
We have a PurchaseOrderHeaderView object and on click of Copy Purchase Order we want to copy a row in PURCHASE_ORDER_HEADER table to create a new row. We don't want to copy the primary key only the remaining fields.
Regards
Madhuri

If you use ADF BC, you can create a new row programatically via createRow and use a sequence to create the Id and use the "original" row (probably the current row in the view object) to copy the values from to newly created row. Then use insertRow and commit to create the copied row.

How do I select rows from the same table that have multiple occurances

Hi Everybody,
I am trying to select records from a detail table by grouping it. The table has more than 1 million records and the query is not performing well. The basic question is how to select a distinct record from a table which matches all values in one column and any in the other.
desc SCV
ID NUMBER PK (ID + SCRID)
SCRID NUMBER FK(SC)
ID SCRID
1 1
2 1
3 1
4 2
5 2
6 3
7 4
8 4
desc PROJECTS
ID NUMBER PK
NAME VARCHAR2(100)
ID NAME
1 PROJECT1
2 PROJECT2
3 PROJECT3
4 PROJECT4
desc PJS
ID NUMBER
PROID NUMBER FK (PROJECTS)
SCRID NUMBER FK (SCV(SCRID + SCVID)
SCVID NUMBER
ID PROID SCRID SCVID
1 1 1 1
2 1 1 2
3 1 2 5
4 1 3 6
5 1 4 7
6 2 1 3
7 2 2 4
8 2 2 5
9 2 4 7
There are over 1 million records in PJS.
desc TBP
SCRID NUMBER
SCVID NUMBER
SCRID SCVID
1 1
1 2
1 3
2 4
2 5
3 6
4 7
4 8
The requirement is to select projects that have matching SCRID, SCVID from TBP such that
all distinct SCRID should match and within that and any SCVID match will do. (A "AND" between each SCRID and an "OR" for each SCVID in that SCRID like 'SCRID = 1 AND (SCVID = 1 OR SCVID = 2 OR SCVID = 3) AND SCRID = 2 AND (SCVID =....)
So, for the sample data it should return us PROID = 1
I have few queries written for this:
SELECT PROID FROM PJS,TBP WHERE TBP.SCVID = PJS.SCVID AND TBP.SCRID = 1
INTERSECT
SELECT PROID FROM PJS,TBP WHERE TBP.SCVID = PJS.SCVID AND TBP.SCRID = 2
INTERSECT
SELECT PROID FROM PJS,TBP WHERE TBP.SCVID = PJS.SCVID AND TBP.SCRID = 3
INTERSECT
SELECT PROID FROM PJS,TBP WHERE TBP.SCVID = PJS.SCVID AND TBP.SCRID = 4
This query performs well but the cost is very high, hardcoding, sorting.
The 2nd option is to:
SELECT pjs.PROID proid
FROM TBP tbp,
PJS pjs
WHERE pjs.SCVID = tbp.SCVID
AND pjs.SCRID = tbp.SCRID
GROUP BY pjs.PROID
HAVING COUNT(DISTINCT pjs.SCRID) = (SELECT COUNT(DISTINCT SCRID ) FROM TBP)
This has a low cost but runs slowly.
One more way I tried was with the IN operator like
SELECT DISTINCT PROID FROM PJS A,TBP T WHERE T.SCRID = 1 AND T.SCVID = A.SCVID
AND PROID IN (SELECT PROID FROM PJS A,TBP T WHERE T.SCRID = 2 AND T.SCVID = A.SCVID
AND PROID IN (...SO ON with each DISTINCT SCRID.
Again this involves too much of sorting.
Any help will be appriciated.
Thanks in advance.

Hi Andrew,
Use DELETE t_itab statement inside the loop.
I have modified your code. It is perfectly working.See bellow -
LOOP AT it_zmember01 INTO wa_zmember01.
WRITE: / wa_zmember01-mnumber UNDER 'NUMBER',
wa_zmember01-mname UNDER 'NAME',
wa_zmember01-mdob UNDER 'DOB'.
WRITE / '-----------------------------------------------------------------'.
DELETE it_zmember01. " Modified
ENDLOOP.
DELETE it_zmember01. statement inside the loop will delete the current row of the table.

Concatenate rows from the same table

Hi,
I have a table t1 with one column and 2 rows. I need to make a column with 1 row that is a concatenation of the rows from table t1.
Can someone help me with this?

Retriving multiple rows from the same table

Hi all,
I have a table consisting of an id column as well as a start and end date.
What I want to do is select the difference between start and end time for different id's.
For example select (endtime where id = 1 - starttime where id = 2).
Is this possible to do using a single select statement?
Thanks ppl

OK, so you want every combination of dropped_id 500 with dropped_id 1000? For example:
WITH test_data as (SELECT 500 dropped_id, TO_DATE('13/05/2009', 'DD/MM/YYYY') insert_date, TO_DATE('12/05/2009 12:00:00', 'DD/MM/YYYY HH24:MI:SS') starttime, TO_DATE('12/05/2009 12:30:00', 'DD/MM/YYYY HH24:MI:SS') endtime FROM DUAL UNION ALL
SELECT 500, TO_DATE('12/05/2009', 'DD/MM/YYYY'), TO_DATE('11/05/2009 12:04:00', 'DD/MM/YYYY HH24:MI:SS') starttime, TO_DATE('11/05/2009 12:41:00', 'DD/MM/YYYY HH24:MI:SS') endtime FROM DUAL UNION ALL
SELECT 500,TO_DATE('11/05/2009', 'DD/MM/YYYY'), TO_DATE('10/05/2009 12:18:00', 'DD/MM/YYYY HH24:MI:SS') starttime, TO_DATE('10/05/2009 12:59:00', 'DD/MM/YYYY HH24:MI:SS') endtime FROM DUAL UNION ALL
SELECT 1000,TO_DATE('13/05/2009', 'DD/MM/YYYY'), TO_DATE('12/05/2009 12:30:00', 'DD/MM/YYYY HH24:MI:SS') starttime, TO_DATE('12/05/2009 13:30:00', 'DD/MM/YYYY HH24:MI:SS') endtime FROM DUAL UNION ALL
SELECT 1000,TO_DATE('12/05/2009', 'DD/MM/YYYY'), TO_DATE('11/05/2009 12:41:00', 'DD/MM/YYYY HH24:MI:SS') starttime, TO_DATE('11/05/2009 14:30:00', 'DD/MM/YYYY HH24:MI:SS') endtime FROM DUAL UNION ALL
SELECT 1000,TO_DATE('11/05/2009', 'DD/MM/YYYY'), TO_DATE('10/05/2009 12:19:00', 'DD/MM/YYYY HH24:MI:SS') starttime, TO_DATE('10/05/2009 13:30:00', 'DD/MM/YYYY HH24:MI:SS') endtime FROM DUAL)
-- end test data

inner join @forumsTable f2
on f1.activityID = f2.activityID
and f1.officeID > 0
and f2.employeeID > 0
and f1.id - f2.id = -1
You really need to improve the relationship here.
Perhaps you could make office and activity an exclusive pair.

Two triggers in the same table and event

If I created two triggers on the same table and event (before insert), which of them will be triggered first ?...
The problem from the beginning is that I created the second one as after insert and in the body of the trigger I wrote (:new.xxx:= value) ... then an error (that it should be before insert trigger or update trigger), so I created it as before update ,,, but I have already before update trigger (for primary key)..... and the problem -I think- which of them start first...
Can make the second one as after insert and make update statement instead of assigning (:new.xxx:= value).....

If I created two triggers on the same table and event
(before insert), which of them will be triggered
first ?...As already mentioned, prior to 11g the order of firing is undetermined.
The problem from the beginning is that I created the
second one as after insert and in the body of the
trigger I wrote (:new.xxx:= value) ... then an error
(that it should be before insert trigger or update
trigger), so I created it as before update ,,, but I
have already before update trigger (for primary
key)..... and the problem -I think- which of them
start first...If there is a conflict of interest inside the code then you will have to alter your design principle around this to cater for it. Also consider combining the code into a single before insert trigger to prevent any confusion.
Can make the second one as after insert and make
update statement instead of assigning (:new.xxx:=
value).....Attempting to update or query the same table as is causing the trigger to fire will result in a mutating table error. You can't do this.

Data of column datatype CLOB is moved to other columns of the same table

Hi all,
I have an issue with the tables having a CLOB datatype field.
When executing a simple query on a table with a column of type CLOB it returns error [POL-2403] value too large for column.
SQL> desc od_stock_nbcst_notes;
Name Null? Type
OD_STOCKID N NUMBER
NBC_SERVICETYPE N VARCHAR(40)
LANGUAGECODE N VARCHAR(8)
AU_USERIDINS Y NUMBER
INSERTDATE Y DATE
AU_USERIDUPD Y NUMBER
MODIFYDATE Y DATE
VERSION Y SMALLINT(4)
DBUSERINS Y VARCHAR(120)
DBUSERUPD Y VARCHAR(120)
TEXT Y CLOB(2000000000)
NBC_PROVIDERCODE N VARCHAR(40)
SQL> select * from od_stock_nbcst_notes;
[POL-2403] value too large for column
Checking deeply, some of the rows have got the data of the CLOB column moved in another column of the table.
When doing select length(nbc_providercode) the length is bigger than the datatype of the field (varchar(40)).
When doing substr(nbc_providercode,1,40) to see the content of the field, a portion of the Clob data is retrieved.
SQL> select max(length(nbc_providercode)) from od_stock_nbcst_notes;
MAX(LENGTH(NBC_PROVIDERCODE))
162
Choosing one random record, this is the stored information.
SQL> select length(nbc_providerCode), text from od_stock_nbcst_notes where length(nbc_providerCode)=52;
LENGTH(NBC_PROVIDERCODE) | TEXT
-------------------------+-----------
52 | poucos me
SQL> select nbc_providerCode from od_stock_nbcst_notes where length(nbc_providerCode)=52;
[POL-2403] value too large for column
SQL> select substr(nbc_providercode,1,40) from od_stock_nbcst_notes where length(nbc_providercode)=52 ;
SUBSTR(NBC_PROVIDERCODE
Aproveite e deixe o seu carro no parque
The content of the field is part of the content of the field text (datatype CLOB, containts an XML)!!!
The right content of the field must be 'MTS' (retrieved from Central DB).
The CLOB is being inserted into the Central DB, not into the Client ODB. Data is synchronized from CDB to ODB and the data is reaching the client in a wrong way.
The issue can be recreated all the time in the same DB, but between different users the "corrupted" records are different.
Any idea?

SQL and PL/SQL FAQ

Compare two rows in a same table

Dear all
I need to compare two rows in the same table, I dont know hoe to do it in pl/sql. Some one please help me on this.
example:
tr br price
xya0001 ama7 12
xya0003 ama6 14
xya0004 ama7 16
in the table tr is a unique value for each row, I need to compare price column and see whether the first value is less or greater than the next value and, if it is greater put the corresponding br value to a variable and if it is smaller put the corresponding br value to another variable. I dont know a method to do it, as I'm new to pl/sql. Some one please help me in this

not sure what you intend to do as you have mentioned that "TR" is unique and you just want to compare each record with just the next record. Hope below query helps. The value "G" or "L" in flag would indicate if the current records price is greater than or less than the price in next record.
select tr,br,price,col4, case when price> col4 then 'G' when price< col4 then 'L' end flag from (
select tr,br,price,lag(price,1,0) over(order by tr) col4 from testcomp
)

Copy/Paste cells in the same table

How can I copy/paste rows inside the same table?
I tried with ITableModel, but its function CanPaste() returns me kFalse. And I tried with kTableCopyPasteCmdBoss/ITableCopyPasteCmdData, it crashed.
Thank you in advance,
David

You are correct, but this behavior has always amazed me. ID *never* inserts the correct amount of copied rows inbetween others -- rather, you have to count how much you are going to copy, then insert blanks, then paste, then double-check you didn't accidentally overwrite existing ones!
If you are writing a general plugin to handle tables, you might think about doing this automatically. I don't know, perhaps you can test how much rows are "in the copy buffer" at the time of pasting.
