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,

Multiple (updatable) details in the same page.

Hello,
I tried to put two updatable details in the same page and got the error
"Updatable SQL Query already exists on page 11. You can only add one updatable SQL query per page. Select a different page"
So having more than one updatable detail is not allowed in apex ?
I have a master table with three details. Should I create one page for each one of them ?
Thanks in advance

What you want to use are called collections. Here is a simple collection example:
The process goes in 4 steps: gather the data, display the data, update based on user input, then write the changes. Each step requires it's own piece of code, but you can extend this out as far as you want. I have a complex form that has no less than a master table and 4 children I write to based on user input, so this can get as complex as you need. Let me know if anything doesn't make sense.
First, create the basic dataset you are going to work with. This usually includes existing data + empty rows for input. Create a Procedure that fires BEFORE HEADER or AFTER HEADER but definitely BEFORE the first region.
DECLARE
v_id     NUMBER;
var1     NUMBER;
var2     NUMBER;
var3     VARCHAR2(10);
var4     VARCHAR2(8);
cursor c_prepop is
select KEY, col1, col2, col3, to_char(col4,'MMDDYYYY')
    from table1
    where ...;
i         NUMBER;
cntr      NUMBER := 5; --sets the number of blank rows
BEGIN
OPEN c_prepop;
    LOOP
      FETCH c_prepop into v_id, var1, var2, var3, var4;
      EXIT WHEN c_prepop%NOTFOUND;
        APEX_COLLECTION.ADD_MEMBER(
        p_collection_name => 'MY_COLLECTION',
        p_c001 => v_id, --Primary Key
        p_c002 => var1, --Number placeholder
        p_c003 => var2, --Number placeholder
        p_c004 => var3, --text placeholder
        p_c005 => var4 --Date placeholder
    END LOOP;
CLOSE c_prepop;
for i in 1..cntr loop
    APEX_COLLECTION.ADD_MEMBER(
        p_collection_name => 'MY_COLLECTION',
        p_c001 => 0, --designates this as a new record
        p_c002 => 0, --Number placeholder
        p_c003 => 0, --Number placeholder
        p_c004 => NULL, --text placeholder
        p_c005 => to_char(SYSDATE,'MMDDYYYY') --Date placeholder
end loop;
END;Now I have a collection populated with rows I can use. In this example I have 2 NUMBERS, a TEXT value, and a DATE value stored as text. Collections can't store DATE datatypes, so you have to cast it to text and play with it that way. The reason is because the user is going to see and manipulate text - not a DATE datatype. If you are using this as part of a master/detail form, make sure that your SQL to grab the detail is limited to just the related data.
Now build the form/report region so your users can see/manipulate the data. Here is a sample query:
SELECT rownum, apex_item.hidden(1, c001), --Key ID
     apex_item.text(2, c002, 8, 8) VALUE1,
     apex_item.text(3, c003, 3, 3) VALUE2,
     apex_item.text(4, c004, 8, 8) VALUE3,
     apex_item.date_popup(5, null,c005,'MMDDYYYY',10,10) MY_DATE
FROM APEX_COLLECTIONS
WHERE COLLECTION_NAME = 'MY_COLLECTION'This will be a report just like an SQL report - you're just pulling the data from the collection. You can still apply the nice formatting, naming, sorting, etc. of a standard report. In the report the user will have 3 "text" values and one Date with Date Picker. You can change the format, just make sure to change it in all four procedures.
What is critical to note here are the numbers that come right before the column names. These numbers become identifiers in the array used to capture the data. What APEX does is creates an array of up to 50 items it designates as F01-F50. The F is static, but the number following it corresponds to the number in your report declaration above, ie, F01 will contain the primary key value, F02 will contain the first numeric value, etc. While not strictly necessary, it is good practice to assign these values so you don't have to guess.
One more note: I try to align the c00x values from the columns in the collection with the F0X values in the array to keep myself straight, but they are separate values that do NOT have to match. If you have an application you think might get expanded on, you can leave gaps wherever you want. Keep in mind, however, that you only have 50 array columns to use for data input. That's the limit of the F0X array even though a collection may have up to 1000 values.
Now you need a way to capture user input. I like to create this as a BEFORE COMPUTATIONS/VALIDATIONS procedure that way the user can see what they changed (even if it is wrong). Use the Validations to catch mistakes.
declare
j pls_integer := 0;
begin
for j1 in (
select seq_id from apex_collections
where collection_name = 'MY_COLLECTION'
order by seq_id) loop
j := j+1;
--VAL1 (number)
apex_collection.update_member_attribute (p_collection_name=> 'MY_COLLECTION',
      p_seq=> j1.seq_id,p_attr_number =>2,p_attr_value=>wwv_flow.g_f02(j));
--VAL2 (number)
apex_collection.update_member_attribute (p_collection_name=> 'MY_COLLECTION',
      p_seq=> j1.seq_id,p_attr_number =>3,p_attr_value=>wwv_flow.g_f03(j));
--VAL3 (text)
apex_collection.update_member_attribute (p_collection_name=> 'MY_COLLECTION',
      p_seq=> j1.seq_id,p_attr_number =>4,p_attr_value=>wwv_flow.g_f04(j));
--VAL4 (Date)
apex_collection.update_member_attribute (p_collection_name=> 'MY_COLLECTION',
      p_seq=> j1.seq_id,p_attr_number =>5,p_attr_value=>wwv_flow.g_f05(j));
end loop;
end;Clear as mud? Walk through it slowly. The syntax tells APEX which Collection (p_collection_name), then which row (p_seq), then which column/attribute (p_attr_number) to update with which value (wwv_flow.g_f0X(j)). The attribute number is the column number from the collection without the "c" in front (ie c004 in the collection = attribute 4).
The last one is your procedure to write the changes to the Database. This one should be a procedure that fires AFTER COMPUTATIONS AND VALIDATIONS. It uses that hidden KEY value to determine whether the row exists and needs to be updated, or new and needs to be inserted.
declare
begin
--Get records from Collection
for y in (select TO_NUMBER(c001) x_key, TO_NUMBER(c002) x_1,
             TO_NUMBER(c003) x_2,
             c004 x_3,
             TO_DATE(c005,'MMDDYYYY') x_dt
           FROM APEX_COLLECTIONS
           WHERE COLLECTION_NAME = 'MY_COLLECTION') loop
    if y.x_key = 0 then --New record
        insert into MY_TABLE (KEY_ID, COL1,
            COL2, COL3, COL4, COL5)
          values (SEQ_MY_TABLE.nextval, y.x_1,
              y.x_2, y.x_3, y.x_4, y.x_dt);
    elsif y.x_key > 0 then --Existing record
        update MY_TABLE set COL1=y.x_1, COL2=y.x_2,
             COL3=y.x_3, COL4=y.x_4, COL5=y.x_dt
         where KEY_ID = y.x_key;
    else
      --THROW ERROR CONDITION
    end if;
end loop;
end;Now I usually include something to distinguish the empty new rows from the full new rows, but for simplicity I'm not including it here.
Anyway, this works very well and allows me complete control over what I display on the screen and where all the data goes. I suggest using the APEX forms where you can, but for complex situations, this works nicely. Let me know if you need further clarifications.

Multiple and conditions in the same table

Ok I am going to kick myself for this, but I can't figure it out. I am trying to figure out how to find employees which match multiple criteria in the same table.
create table emp
(empno number,
name varchar2(10))
create table skills
(skill_id   number,
skill_code varchar2(20))
create table emp_skills
(empno    number,
skill_id number,
rating   number)
insert into emp values(1, 'SMITH');
insert into emp values(2, 'JONES');
insert into skills values (1, 'SQL');
insert into skills values (2, 'PLSQL');
insert into skills values (3, 'JAVA');
insert into emp_skills values(1,1, 8);
insert into emp_skills values(1,2, 9);
insert into emp_skills values(1,3, 10);
insert into emp_skills values(2,1,9);
insert into emp_skills values(2,2,2);
insert into emp_skills values(2,3,7);Now I need to come up with a query finding all employees who match all 3 of the following criteria:
1) Have at least a 5 rating in SQL
2) Have at least a 6 rating in PLSQL
3) Have at least a 7 rating in JAVA
So using this I would expect to return only SMITH since his/her skills meet all 3 criteria. I dont want to use OR in my query since I want all 3 to match not just one of them.
I have a feeling I will need to self join the table - but this is going to be part of a dynamic query for APEX where the users can choose the skills and ratings they want employees to adhere to, so I dont know the number of criteria or the exact criteria in advance. But I figure if I can get a proof of concept SQL I can make it work dynamically.
Any ideas are appreciated - sorry for the long post but I figure more detail is better

with es1 as(
select s.skill_code, es.empno, es.rating
from skills s, emp_skills es
where s.skill_id = es.skill_id
/* main */
select e.*
from emp e
where
exists
(select 'x' from es1
where es1.rating >= 5
and es1.skill_code = 'SQL'
and es1.empno = e.empno)
and

(select 'x' from es1
where es1.rating >= 6
and es1.skill_code = 'PLSQL'
and es1.empno = e.empno)
and

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).

Multiple language data in the same table and indexes

We have 8.1.5 database with
NLS_LANGUAGE=ENGLISH and NLS_TERRITORY=UNITED KINGDOM set at the database level. We also set the NLS_LANG appropriately when we index the data. We also use the preference setting BASE_LETTER=YES when indexing.
Our tables contain book titles which is what we index using interMedia. Being an online book store, this table may contain titles in English (most of the titles are in English being UK) and some titles in French. Please note the French language has accents and diacritics. Normally in a French database with NLS parameters set correctly and BASE_LETTER=YES, if we search for a title with accent / diacritic it will return the record correctly and match the rows with or without the accents (e.g. searching for video will return both vidio (not the accent on e) and video). However, with the UK settings the accents are not ignored during indexing and it only returns the records that exactly match the search word (e.g. searching for video returns only video and searching for vidio returns only vidio (note the accents on e in the last two videos)).
Question: Is there any way to appropriately index multiple language specific titles in the same database? If yes, how? Is it possible at all? Suggestions, ideas are welcome.
null

Similar request; if there are several different languages used in a database, but a search word can be typed in by anyone and not necessarily in the default language, I still want to be able to pick up all the records (including text in blobs) in any language where my search word = the equivelant word in the other languages; eg. searching on "tree", the search would bring back a document that contained "l'arbre". I then want to set the default language, and allow the user to select a "search in these languages" option to expand the search from the default "tree" to all languages in the database.
I know about the multi_Lexer but does it extend functionality to this level?

Concurrency when inserting in the same table

Hi,
I have a report used by several users and in this record there is a sentence to insert in a z table. My question is, what happens whether two or more users are inserting records in that table at the same time? There is a concurrency problem, isn't there?
How does SAP manage this issue? or, what must I do in this case?
Thanks in advance.
Regards.

Hi David,
As SAP applications are accessed by many end users at same time, SAP has concept called LOCKING of particular tables involved in the transaction.
You can achieve your requirement as below
Go to t-code SE11, and create a lock object for your Ztable
Now, system create 2 function modules - 1 for locking ENQUEUE_* & other for un-locking DEQUEUE_* ( search for function module in SE37 )
Before saving data to ZTABLE, call function module ENQUEUE_* to lock the table for writing data, if locking fails, means there is somebody already working on it, hence you can display error message
After Save action, you can unlock the table by using FM ... DEQUEUE_*
Note: you can lock and unlock event during DISPLAY/CHANGE mode if your requirement requires.
Hope this helps you.
Regards,
Rama

Parallel Insert statements (bulk) to the same table

Hi,
I am in need to insert set of insert statements 50000+ in to table and wanted to split them in to tow halves and run in two SQL worksheets.
Note that both will try to insert on the same table.
Please let me know whether it is advisable or tell me an alternative way.
Using...Oracle 11g DB.
Regards
Deep.

Not sure why you want to split it. Parallel inserts into the same table is not usually a problem. Contention could be around free lists, initrans and so on - especially if using RAC and inserting something like 50,000+ rows every second. But the table defaults usually suffice.
Note that both will try to insert on the same table.So what? This is exactly what Oracle expects and what it is designed to do.
Please let me know whether it is advisable or tell me an alternative way.Well, you mentioned SQL worksheets - why? Exactly how does the INSERT statements look like? Where does the data to insert come from? Is shared insert cursors used (bind variables compulsory)? The bottleneck and problem could very well be on your side and not with the actual inserts into the table.

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.

CLR trigger - handling multiple inserts at the same time

Hi
I've developed a CLR trigger which operates on inserts performed on a staging table. The trigger implements some business logic and then inserts or updates a record in a target table. Whether an insert or update is performed depends on whether
a record with the same ID already exists in the target (i.e. a select * from target where ID = 123).
This works fine in most scenarios, but occasionally I am getting duplicates in the target table and have noticed that this seems to occur when inserts on the staging table happen at exactly the same time (i.e. multiple inserts for the same ID at
the same time). In this situation duplicates are created in the target table because at the time of the inserts, no record with that ID exists in the target table (i.e. the select returns no records), therefore a new record is created for each.
Is there a known way to deal with this scenario? For example, would locking the target table on insert result in the subsequent selects against the target table waiting until the target table had been updated, therefore the select would return a record
for the given ID.
I didn't really want to lock the whole target table on insert, because there are potentially other users reading that table (selects) and these would also have to wait for the insert to complete.
I'd appreciate any thoughts on how to deal with this and avoid duplicates in the target table. I'm unable to change the way the data is coming in to the staging table, so my trigger code must deal with the above scenario.
Thanks in advance.
John

First if you do not want any duplicate values in a column (or combination of columns) you should add a constraint to ensure this is never possible. A
unique index
like this should do this trick.
CREATE UNIQUE NONCLUSTERED INDEX [IX_yourIndexName] ON [dbo].[YourTableName]
[yourColumn1] ASC,
-- add more columns that make the unique combination that you don't want repeated
You can then add a try/catch block in your trigger code, if you get an exception based on this index then the record was created by another executing instance of this trigger and in that case you should do an update (or not, not sure what the rest of your
logic is) in your catch block. This is the easiest solution and does not involve table locks. The only drawback is the first one to commit the insert will win and you have no guarantee which process or data set that will be. Also i have no idea how big the
table is, how frequently changes are made, and what the data type is so you should
keep this in mind when creating your index so you don't run into unexpected high index fragmentation which can lead to performance problems when executing updates and inserts.
You could also create a
named transaction with scope serializable around your insert/update block and execute your reads using a
NOLOCK hint
which should allow them to retrieve uncommitted writes and not create a long wait. The downside is is that the data might not be 100% accurate depending on if a transaction fails or not if there happens to be an update at the same time as a select but maybe
this is not a big deal to the calling code.

Trigger to Update in the same table.

Hi,
I would like to create a trigger that when we insert into table ALL_CAPACITY_SNS_CELL1 it updates column Action on teh same table,if teher is an update, it will update the same table , column ACTION.
This is what I have attempted but seems to be technically wrong.
<pre>
create table ALL_CAPACITY_SNS_CELL1
( A varchar2,
action char(2),
date_executed date);
create or replace
TRIGGER ALL_CAPACITY_HISTORY_TRACKING

DECLARE
v_operation VARCHAR2(10) := NULL;
BEGIN
IF INSERTING THEN
v_operation := 'I';
ELSIF UPDATING THEN
v_operation := 'U';
ELSE
v_operation := 'D';
END IF;
IF INSERTING
UPDATE ALL_CAPACITY_SNS_CELL1
SET ACTION =v_operation,

Nsert/Update and Add Column at the same Table and at the "same" Time

Hello,
I want Insert/Update and Add Column at the same Table and at the "same" Time but in different sessions.
Example:
At first the "insert/update" statement:
Insert into TestTable (Testid,Value) values (1,5105);
After that the "add" statement:
Alter table TestTable add TestColumn number;
- sadly now I get the message: ORA-00054: resource busy and acquire with NOWAIT specified
"insert/update" statement:
Insert into TestTable (Testid,Value) values (2,1135);
After that the execute commit.
I don't know when the first session set the commit statement so I want that the DB the "Alter Table..." statement execute if it's possible.
If it's possible I want to save a repeat loop with the "Alter Table..." statemtent.
Thanks for ideas

Well I want to walk in the rain without and umbrella and still stay dry, but it ain't gonna happen.
You can't run a DDL statement against a table with transactions pending. Session 2 has to wait until session commits or rollbacks (or until the session is killed). That's just the way it is.
This makes sense if you think about it. The data dictionary has to be consistent across all sessions. If session 2 was allowed to change the table structure whilst session 1 has a pending transaction then the database is in an inconsistent state. This is easier to see if you consider the reverse situation - the ALTER TABLE statement run by session 2 does a DROP COLUMN TESTID rather than adding a column: now what should happen to session 1's INSERT statement? You have retrospectively invalidated a statement that was perfectly legal when it was executed.
If it's possible I want to save a repeat loop with the "Alter Table..." statemtent.Fnord.

Load Data from a table on one server's database, to the same table structure in multiple server databases

Hi,
I have a situation where i have to load data from one server/database table to multiple servers/databases.
Example:
I need to load data from dbo.TABLE_A (on Server: Server_A & Database: Database_A) to the same table on the list of server databases like
Server: Server_B , Database: Database_B
Server: Server_C , Database: Database_C
Server: Server_D , Database: Database_D
Server: Server_E , Database: Database_E
Server: Server_F , Database: Database_F
Server: Server_G , Database: Database_G
Server: Server_H , Database: Database_H
so on and so forth on 250 such server database combinations.
The table structure is the same on all the servers.
If i make the source or destination dynamic, it throws an error while mapping ?
I cannot get Linked server permissions and SQL Server Config thing doesn't work as well.
Please suggest on how to load data from one source to multiple server/databases.
Thank you.

I just need to transfer one table's data. its like i have to use a query to pick data for
the most recent data. So i use something like, select A, B, C, D from dbo.table where ETL_TIMESTAMP > (the max(etltimestamp) in the destination on different server). There are no foreign key relationships and the data should not be truncated. it just had
to append the new records.

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 :
CREATE OR REPLACE TRIGGER GDE_COMPS_BRU_5 BEFORE
UPDATE OF DEPARTEMENT--, DISCIPLINE, DEG_DEMANDE, CE_ETAB
ON GDEM.COMPOSITION_SUBV
FOR EACH ROW

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.

How to update a table (CUSTOMER) on a Report Server with the data from the same table (CUSTOMER) from another server Transaction server?

I had an interview question that is:
How to update a table (Customer) on a server ex: Report Server with the data from the same table (Customer) From another server ex: Transaction server?
Set up steps so inset, update or delete operation takes place across the servers.
It would be great if someone please enlighten me in details about this process in MS SQL Server 2008 R2.
Also please describe would it be different for SQL Server 2012?
If so, then what are the steps?

Set up steps so that inset, update or delete operation gets done correctly across servers.
I was not sure about the answer, it would be great if someone please put some light on this and explain in details about this process in MS SQL Server 2008 R2.
Also it would be very helpful if you please describe would it be different for SQL Server 2012? If so, then what are the steps?

Inserting a LONG to a BLOB in the same table

I have a table with a LONG column and would like to concatenate all existing columns into a new column in the same table and define it as a BLOB. I'm trying to figure out a way to do this. I tried the following and got error message
insert into cma_search_test
select obj_id,
     line_id,
     doc_nmbr,
     supplier_part_num,
     mnfctr,
     mnfctr_part_nmbr,
     line_desc,
     ext_desc_txt,
     vend_name,
     cma_effect_dt,
     cma_expir_dt,
     last_updt_usr,
     last_updt_tmsp,
     obj_id||
     line_id||
     doc_nmbr||
     supplier_part_num||
     mnfctr||
     mnfctr_part_nmbr||
     line_desc||
     to_lob(ext_desc_txt)||
     vend_name||
     cma_effect_dt||
     cma_expir_dt||
     last_updt_usr||
     last_updt_tmsp "All_Columns"
from cma_search
to_lob(ext_desc_txt)||
ERROR at line 22:
ORA-00932: inconsistent datatypes
Any help would be appreciated.
Thanks,
Tracy

You cannot concatenate a LONG field. You will have to use a procedure to accomplish what you want.
Use the DBMS_LOB package.
