Conditional insert in plsql

Hi friends,
I am a beginner in Oracle PLSQL. I need to insert a row into a table based on a condition. The condition is to check if the value is already there in another table.
i.e, If the username is already present in the users table then the username should not be added to username table. I have written a stored procedure to insert into the username table but need i do not know how to check for the condition.
Could you please let me know how to get this. I tried a lot but getting compilation errors.
Regards,
Padeep

Use Control Statements
http://download.oracle.com/docs/cd/E11882_01/appdev.112/e17126/controlstatements.htm
Such as: IF-THEN-ELSE or CASE
That documentation is for 11.2. Your Oracle version may be different, but since IF statements have been around for a long time, this will do.
Alternatively, consider a unique index on the field.
http://download.oracle.com/docs/cd/E11882_01/server.112/e17120/indexes003.htm#ADMIN11724
Or even consider using a MERGE statement:

MERGE w/ conditional Insert clause

Hi--
Sum Up:Is it possible to run Merge syntax with update and a conditional Insert clauses ?
Question Details
Have a base table Emp and staging table New_Emp with a common identifier Emp_id.
The ideal would be to merge the 2 tables and update Emp using New_Emp values and
insert only some new emp, not all records.
Any ideas ? Thks
Lamine

Absolutely. See the docs. Use the WHEN and WHERE clauses.

Implementing Conditional Insert

I use tips in the article "Implementing Conditional Insert, Update, and Delete Allows for View Objects" from "Steve Muench's Radio Weblog".
At the start all it's ok, but I found this problem:
1. I have two views (V1 and V2) over the same entity (E1)
2. V1 permit insert, delete, update, and select.
3. V2 overwrite method create and don't allow insert.
4. If you use V1 and try to insert a record all go ok.
5. If you use V2 and try to insert a record get an exception "It's not allow insert into V2", It's Ok.
6. If you use V1 again and try to insert a record you get an exception, that say "It's not allow insert into V2".
I'm investigate the case, and found that when you insert a record in E1 throw V1, the framework (BC4) try to create the record in the views that are instantiated over the entity E1, for this call method "create" on views.
Do you know some workaround ?
thank in advice...

Hi, again, I have question about this...
I post it in the forum...
If I use "isAssociationConsistent()" I have to know all views that depend of same entity, and its privileges. I have problem with that because if I add a view a have to remember to put this in the code.
I need to confirm: is return of method "this.getEntity(0).isInCache()" true when record was inserting in other entity ?
May I modify your sample like this:
public class CustomViewRowImpl extends ViewRowImpl {
protected void create(AttributeList nvp) {
if ( this.getEntity(0).isInCache() || getVO().isInsertAllowed()) {
super.create(nvp);
else {
throw new JboException("Insert not allowed in this view");
thank a lot

nanthaHmmm let's look at the conversation so far...
You: "is this possible?????"
Me: "No."
You: "is there is any possible way to do so????"
I'm now wondering which part of "No" you failed to understand.
You cannot perform multiple/conditional inserts within a MERGE statement. The purpose of a MERGE statement is to take data and MERGE it into a single table.
The only messy way I can think of would be to merge into an intermediate table with triggers on it, that takes the merged data and splits it out into the seperate tables. Messy and not likely the best solution to the initial problem, which would probably be better solved by avoiding the use of MERGE in the first place (though we don't know what problem you are actually trying to solve).

Conditional Insert

Hi,
Is it possible to do a conditional insert? e.g.
IF :P2_NAME != (SELECT name from hk.appname where name = :P2_NAME) then
INSERT....
END IF;So if the value of :P2_NAME doesn't exist within the table then it will be inserted...its to be an addition to a currently existing APEX process (checks that field values aren't null then enters a record into a different table than hk.appname).
Thanks for any help.

Conditionally inserting tiles

Hello All,
I am using tiles with JSF. In my jsf page, i have the below logic but still the tiles get inserted...
<% if(false){ %>
<tiles:insert definition="NonMember" flush="false"/>
<% } %>
I am not sure whats happening.. does anyone know whats happening here...
Basically,i want to check a condition and if the condition is false, i dont want to insert the tiles..

Make sure nonMember definition is accessible via the jsp page:
<f:verbatim>
<%
String nonMember = ...
if(false)
%>
<tiles:insert name="<%=nonMember%>" flush="false" />
<%

(no inline validation error displayed)) condition type and plsql expression

Hello all
Is it possible to use a plsql expression (eg: (:REQUEST = 'PXX_LIST_ITEM')) AND (no inline validation error displayed)) condition type at the smae time ?
HTMLDB must be testing a substitution variable when the conditional display section is set to 'no inline validation errors displayed'.

Hello,
I don't know for sure because I never used it, but I think you can use the pl/sql variable htmldb_application.g_inline_validation_error_cnt. This variable identifies number of inline errors found.
You can also check if the variable htmldb_application.g_notification contains a value.

Conditional Insertion in table based on Field

Hi all,
I am having 3 text input fields in my page, Empno, Ename, Sal
After inserting data in the fields, commission column has to be populate automatically, based on conditions.
Conditions are : If the salary is less than 5000 the commission 500 has to be insert, salary is greater than 5000 commission 1000 has to be inserted.
how can I achieve this, and where I have to implement the logic, please help me out.
Thanks in Advance
Jagadish

Hi,
You can apply PPR on salary field. Then catch the event and based on condition, set the value of commission field.
Also, you can check this link for PPR:

INSERT in PLSQL loop in Oracle 9i scheduled job has poor performance

Hi,
I have a scheduled job running in Oracle 9i. But everytime it executes the following piece of code, the INSERT process slows down drastically.
-------------------------------typical piece of code having problem-----------------------------------
LOOP
FOR increbkgs IN bookings_cur (in_chr_fiscal_period_id,
allrec.cust_name_string
LOOP
l_num_rec_count := l_num_rec_count + 1;
INSERT INTO SA_PORTAL_CDW_BOOKINGS_INCTEMP
(product_id, territory_code,
global_target_id, service_type,
equipment_deployment, created_date, updated_date,
fiscal_period_id, customer_id,
ship_to_country,
bookings_amount, sams_alliance_id
VALUES (increbkgs.product_id, increbkgs.territory_code,
increbkgs.global_target_id, increbkgs.service_type,
increbkgs.equipment_deployment, SYSDATE, SYSDATE,
increbkgs.fiscal_period_id, increbkgs.customer_id,
increbkgs.ship_to_country,
increbkgs.bookings_amount, allrec.sams_alliance_id
IF (l_num_rec_count = 500)
THEN
l_num_rec_count := 0;
COMMIT;
END IF;
END LOOP;
END LOOP;
All the tablespaces are auto-extend. But we have still tried to increase the tablespace manually from 2% to 30% by adding datafiles. Still the INSERT is slowing down for some reason.
(The same process in Oracle 8i is much faster)
Any hint or guidance is greatly appreciated.
Thanks and regards,
Ambili

commits in loops are great for slowing down things. Actually commits in loops are just about the best way of stalling any 'process' in Oracle.
A much better way is to resize your undo tablespace to permit one single commit at the end of the whole thing. Yes it could be big, but that's the way Oracle works.

Conditional Insert into staging table by using sqlloader

Hi,
In Oracle apps I'm submitting a concurrent program programmatically which will call sqlloader and insert into a staging a table.
This table consists of 30 columns.Program has one input parameter.If parameter value = REQUIRED Then it should insert into first three columns of staging table.If it's APPROVED then it should insert into first 10 columns of the same table.
Data file is pipe delimited file which may or may not have all possible values :For Required,I many not have all three column values

>
I think you understood the thinks wrongly. OP marked UTL_FILE as the correct answer, which is again a server side solution.
>
Perhaps you failed to notice that the answer now marked correct was posted AFTER mine. I'm not clairvoyant and OP did not state whether a server side or client side solution was appropriate.
I stand by my comments. Using an external table is an alternative to sql loader but, as I said, simply using an external table instead of sql loader doesn't address OPs problem.
>
And IMO, external table will be faster than UTL_FILE
>
I'd be more concerned with why OP wants to write a procedure to parse flat files, deal with data conversion errors and perform table inserts when Oracle already provides that functionality using either external tables or sql loader.
I would suggest loading the file into a new staging table that can hold all of the columns that might be contained in the flat file. Then the appropriate data can be moved to OPs staging table according to the required business rules.
Sounds like we each think OP should reconsider the architecture.

Conditional insertion into a table

Hello:
I've a base table into which records are inserted from results returned by a query. The query always runs on the current date every hour. There are some preconditions before insertion:
1) The backdated records will remain as it is;
2) If query finds a new Number it will be inserted in the table;
3) If query finds a same number but Count is more, it will also inserted in the table.
TABLE1-
Number|PDATE|CATEGORY|MARKED|COUNT
1|29-APR-2012|C1|Y|2
3|30-APR-2012|C1|Y|1

Explain Output: The query is running on 30-Apr-2012
1|29-APR-2012|C1|Y|2: This is a backdated record. So, remained unchanged.
1|30-APR-2012|C1|N|1: 1 of today was not in the table. So, it is inserted with Status 'N'
2|30-APR-2012|C1|N|5: 2 of today was not in the table. So, it is inserted with Status 'N'
3|30-APR-2012|C1|Y|1: 3 is already in the table. So, unchanged.
4|30-APR-2012|C1|N|9: 4 will be inserted cause count (9) is more than previous (1). So, it is inserted with Status 'N'
5|30-APR-2012|C1|Y|3: 5 is already in the table. So, unchanged.
Can anyone help me with query?

Implementing Conditional Insert, Update, and Delete Allows for View Objects

Steve,
Thanks for the info in this article it was very helpful. I have one question as I created a test case that used dept & emp tables as master and detail.
Placing code in the emp detail ViewRowImpl that also tests to see if the master is updateable and it all works fine but I noticed that when you run it in the tester the dept master fields are grayed out but not the emp details and if you bring up the emp detail with out the view link then they are grayed out.
Just wondering is this just a fact of the detail being shown in a table in the master detail and not a form or is there more to it then that??

yes as follows:
isMasterUpdateable checks the Dept table to see if it is updateable before allowing emp to be updated.
public boolean isAttributeUpdateable(int index)
if ( isMasterUpdateable() == true )
return ( super.isAttributeUpdateable(index) );
return(false);
When I run this in the tester the results are correct except for the visual where the form is grayed out but the detail in the table is not. Should the table gray out also or is this effect something that must be coded in all Jtables that i may implement? If it needs to be coded to get the effect where does Jtable check for isAttributeUpdateable ?
thanks,

How to insert some records in one table and some records in another table

it is working fine but he wants to insert some specific litimit on one table and some specified limit of records in one ..
In this senerio can i insert records by use count of records...
please help me..

Can you be more specific on the "Limit"
Conditional insert can be used in this case.

Use of insert in case

Hi,
Is it possible to use insert statement in CASE.
For example as follows:
let create a table as
create table DECOMPENSATED_BALANCE_TMP (ENDING_ENTERED_BALANCE_DR number, ENDING_ENTERED_BALANCE_CR number);
select
CASE
WHEN (PERIOD_NET_DR+BEGIN_BALANCE_DR-PERIOD_NET_CR-BEGIN_BALANCE_CR) total > 0
THEN
INSERT INTO XXGL_DECOMPENSATED_BALANCE_TMP (ENDING_ENTERED_BALANCE_DR) values (total)
WHEN (PERIOD_NET_DR+BEGIN_BALANCE_DR-PERIOD_NET_CR-BEGIN_BALANCE_CR) <= 0
THEN
INSERT INTO XXGL_DECOMPENSATED_BALANCE_TMP (ENDING_ENTERED_BALANCE_CR) values (total)
else
NULL
end
from gl_balances
where code_combination_id=109940 and currency_code='GBP';
Any answers will be highly appreciated ....
Thanks,
zaheer

I don't think that a conditional insert is really needed in this case. THe only part where the insert differse is the else part of your case statment where no insert should be done. THis can be made into a where clause.
An easy way would be to use a simple INSERT + SELECT statement. Where the value for the dr and cr columns are created by a case or a decode statement.
untested example
insert into XXGL_DECOMPENSATED_BALANCE_TMP
(ENDING_ENTERED_BALANCE_DR, ENDING_ENTERED_BALANCE_CR)
select case WHEN (PERIOD_NET_DR+BEGIN_BALANCE_DR-PERIOD_NET_CR-BEGIN_BALANCE_CR) > 0 then total
          else null
          end as DR
         ,case WHEN (PERIOD_NET_DR+BEGIN_BALANCE_DR-PERIOD_NET_CR-BEGIN_BALANCE_CR) <= 0 then total
          else null
          end as CR
from gl_balances
where code_combination_id=109940
and currency_code='GBP'
and (PERIOD_NET_DR+BEGIN_BALANCE_DR-PERIOD_NET_CR-BEGIN_BALANCE_CR) is not null -- else part
;The good thing is you could run this insert statement for several code_combination_ids directly in SQL without any pL-loop.
Just noticed that leonard aready posted almost the same solution.

Maintain Excise defaults for pricing condition in TAXINN procedure

Hi all,
I post this message as I'm customizing CIN part for creation and calculation of excise invoice. I have read lot of post but i'm a bit confused about right procedure to adopt. I try to explain:
I'm doing a stardard sales flow (sales order -> delivery -> commercial invoice -> excise invoice) and the only method I have found to flow excise values in excise invoice is to insert pricing conditions in India -> Basic settings -> Determination of excise duty -> Maintain excise defaults for TAXINN procedure.
In this table I have insert pricing conditions I use in my SD pricing schemas (in this case I use a copy of JINFAC). I have insert pricing conditions corresponding to BED % and BED total, and also CESS % and total and S&HCESS % and total.
If I remove pricing condition from this table, corresponing value in excise invoice, when I create it, become 0.
My dubt is if is correct to populate with table to flow excise values in excise invoice. I ask it as I have read differents approach and differents customizing settings applied in similar situations. In particular, I have found documentation in which, for TAXINN procedure, is recommended to leave blank "excise defaults" (with exception of CVD condition). What is the right method to use?
There is one right procedure or, as it seems reading posts, someone have to do his "proper CIN customizing" based on results that have to obtain?
Thanks in advance for any contribute that can help to clarify this situation.
Regards
Gianpaolo

Hi all,
I think to have found solution to my dubt.
If I use "condition based Excise determination" I have to insert records with pricing schema (if is a copy of standard J* schema, like ZINFAC that is a copy of JINFAC) and excise pricing conditions in the transaction below:
India -> Basic settings -> Determination of excise duty -> Condition-based Excise determination -> Classify condition type
To determine value in excise invoice seems that program check before table in transaction described before. If in this table don't find records for pricing schema-excise pricing condition the program check also table in transaction below:
India -> Basic settings -> Determination of excise duty -> Maintain excise defaults
If during this second check find excise pricing conditions insert, can determine equally the values of excise in excise invoice.
This is the result of my checks. I hope this could be useful for other people with similar problem.
