PL/SQL insert based on conditions

I'd appreciate any help I can get. I learn PL/SQL and have stumbled upon a problem, so please help me to find an appropriate way to deal with this situation I am running Oracle 11 GR 2

My diagram:

CREATE TABLE "ENTRY"
(
'TYPE' VARCHAR2 (5 CHAR) ,
 'TRANSACTION' VARCHAR2()5 TANK),
'OWNER' VARCHAR2 (5 CHAR)
); 

CREATE TABLE "VIEW"
(
'TYPE' VARCHAR2 (5 CHAR) ,
'TRANSACTION' VARCHAR2 (5 CHAR),
'OWNER' VARCHAR2 (5 CHAR)
); 

CREATE TABLE "REJECTED"
(
'TYPE' VARCHAR2 (5 CHAR) ,
'TRANSACTION' VARCHAR2 (5 CHAR),
'OWNER' VARCHAR2 (5 CHAR)
);

My sample data:

insert into entry (type, transaction, owner) values (11111, 11111, 11111);
insert into entry (type, transaction, owner) values (22222, 22222, 22222);

Now for the confusing part, I wrote this procedure which has to copy the values from the table ENTRY in the table VIEW if a record is no specific combination (transaction AND owner). If such an association exists in the table for VIEW this record should then go to the REJECTED table. This procedure done that but on the executions of the procedure, I get more entries in the REJECTED table so my question is how do to limit inserts them into the table of REJECTED - if a record already exists in the REJECTED table then do nothing.

create or replace PROCEDURE COPY AS 
v_owner_entry ENTRY.owner%TYPE;
v_transaction_entry ENTRY.transaction%TYPE; 
v_owner VIEW.owner%TYPE;
v_transaction VIEW.transaction%TYPE; 

begin 

begin 
select e.owner, e.transaction, v.owner, v.transaction
into v_owner_entry, v_transaction_entry, v_owner, v_transaction
from entry e, view v
where e.owner = v.owner and e.transaction = v.transaction; 


EXCEPTION when too_many_rows
then insert into REJECTED ( TYPE, TRANSACTION, OWNER ) SELECT s1.TYPE, s1.TRANSACTION, s1.OWNER FROM ENTRY s1; 

when no_data_found THEN  insert into VIEW ( TYPE, TRANSACTION, OWNER ) SELECT s.TYPE, s.TRANSACTION, s.OWNER FROM ENTRY s; 
end;
end;

Any suggestions guys?

See you soon!

UPDATE

Sorry if the original message was not enough - clear the procedure must replicate data (on a daily basis) of DB1 to DB2 and insert in the VIEW or REJECTED depending on the conditions. Here is a picture, it would be perhaps more clearly:

Hello

your procedure could look something like this:

declare
  -- Local variables here
  i integer;
begin
  -- Test statements here
  INSERT INTO REJECTED
  (TYPE, TRANSACTION, OWNER)
  SELECT ENTRY.TYPE, ENTRY.TRANSACTION, ENTRY.OWNER
    FROM ENTRY, VIEW
   WHERE ENTRY.OWNER = VIEW.OWNER
     AND ENTRY.TRANSACTION = VIEW.TRANSACTION
     AND NOT EXISTS
   (SELECT NULL
            FROM REJECTED VW2
           WHERE VW2.OWNER = ENTRY.OWNER
             AND VW2.TRANSACTION = ENTRY.TRANSACTION);

INSERT INTO VIEW
  (TYPE, TRANSACTION, OWNER)
  SELECT TYPE, TRANSACTION, OWNER
    FROM ENTRY
   WHERE NOT EXISTS (SELECT NULL
            FROM VIEW
           WHERE ENTRY.OWNER = VIEW.OWNER
             AND ENTRY.TRANSACTION = VIEW.TRANSACTION);
COMMIT;
end;

  • Must insert based on condition

    Hi friends,

    I have a form with the following fields

    Course_name, duration, on_date

    A person several can log into the app with a form of opening with the fields above...

    After having all the details in the form of filling and if he pressed 'Send' button, then it will insert in the table...

    *) Assume that assume, if a person (for the first time) is logging into the application and fills it with the following details in the form

    -> course name: oracle
    -> Duration: 21:00 pm
    -> date: 11/06/2011

    and if he pressed the means of the "submit" button, it will insert in the table...

    *) Guess if person B is accessing the request (for the first time, once) and if he meets with the same means (i.e) of following details

    -> course name: oracle
    -> Duration: 21:00 pm
    -> date: 11/06/2011

    It should not be allowed to 'submit' and we must say the error message like

    * "This duration for this course and this date is already reserved by the other person, in order to select another date" * "

    (IE), it should not insert into the table... Because the content of the coursename, duration, date is already inserted...

    It's that these three columns of the row of suceeding values must not be equal. How can I achieve this.


    Kind regards
    Mini

    Hey Mini,

    Change uppercase in the where clause similar to below and this should solve your problem.

    SELECT
  1
FROM
  course
WHERE
  UPPER(course_name) = UPPER(:P1_COURSE_NAME)
AND
  duration = :P1_DURATION
AND
  date = :P1_DATE

    Thank you

if flag1='N' and flag3 = 'N' then then use all_where1 and all_where 3 in *where* clause of select statement...
if all there flag = 'N' then use all_where conditions in *where* clause of select statement...

i have 3 flags, which means total of 9 combinations,  is there any simpler way to do such kind of thing??

    Hi all, I need your help appreciated.

    I do a plsql procedure that inserts a line according to the value of the slider, I have error oracle ORA-00001: unique constraint (constraint_name) violated.

    This message may appear if a duplicate entry exists at a different level: in the RDBMS MySQL, I have the syntax IGNORES to solve this error of duplication... and in Oracle?

    Thanks for your time and your advice.

    How to solve the error ORA-00001 in SQL Insert?

    ORA-00001 means table a unique/primary key / index and you attempt to insert a row with the key value already exists in the table. I'll assume table has a primary key on COUNTRY_ID. Then modify SQL for:

    SQL = "INSERT INTO COUNTRIES (COUNTRY_ID, COUNTRY_NAME, REGION_ID) SELECT"BZ","BLZ", 3 DOUBLE WHERE DOES NOT EXIST (SELECT 1 FROM COUNTRIES WHERE COUNTRY_ID ="BZ").

    There is a good chance COUNTRY table also has unique key/index on COUNTRY_NAME. If so use:

    SQL = "INSERT INTO COUNTRIES (COUNTRY_ID, COUNTRY_NAME, REGION_ID) SELECT"BZ","BLZ", 3 DOUBLE WHERE DOES NOT EXIST (SELECT 1 FROM COUNTRIES WHERE COUNTRY_ID = 'BZ' OR 'BLZ' = COUNTRY_NAME).

  • PL/SQL Insert Row Assign PK Value

    I try to insert a row of data into a table and assign a primary key value. I want to give the first available primary key, not only the nextval in the maxval. Is there a way to do it cleanly, or will I need to create a cursor to do? If I need to create a slider or the sequence, how do I declare it in my procedure? Do I need a sequence so that I couldn't just use a loop for? Please help - it seems such a simple thing, but it has left me speechless.

  • Dynamic action with multiple values of PL/SQL Expression as a condition

    Hel

    I am currently using Apex 4.0 for a schoolproject.

    I have two selectlists (P8_BUSINESSRULETYPE - which has al businessruletypes) and (P8_OPERATOR) that has a select statement based on the businessruletype.

    What is the problem with my dynamic action? Because he does not hide the operatorfield when businessruletype 10 or 9 are selected in the selectlist. Sessions has also said operator = 9 and Businessruletype = 10

    I hope you guys can help out me.

    The first thing is that a Condition that is applied to a control of dynamic action if the dynamic action is made the see page. She has therefore no impact on the question of whether the actions of true or false are performed. Control conditions which are those defined in the when the properties of the dynamic action. As they are evaluated in the browser, they must be specified as JavaScript.

    Secondly, this expression is not valid because it is a space between the colon and the identifiers. Link the names of rating, the colon and the variable element must be contiguous:

    :P8_BUSINESSRULETYPE = 10 OR :P8_BUSINESSRULETYPE = 8  OR :P8_BUSINESSRULETYPE = 7 OR :P8_BUSINESSRULETYPE = 9

    However the latter is only of academic interest, in this case you need to remove the condition of dynamic action.

    In the dynamic of change when action section, P8_BUSINESSRULETYPE, P8_OPERATOR, Condition of JavaScript Expressionand value to the value of the item (s)

       ($v('P8_BUSINESSRULETYPE') == '7')
|| ($v('P8_BUSINESSRULETYPE') == '8')
|| ($v('P8_BUSINESSRULETYPE') == '9')
|| ($v('P8_BUSINESSRULETYPE') == '10')
|| ($v('P8_OPERATOR') == '9')

    If you are using a browser that supported, this can be simplified to

       (['7', '8', '9', '10'].indexOf($v('P8_BUSINESSRULETYPE')) >= 0)
|| ($v('P8_OPERATOR') == '9')

  • Tuning sql insert that inserts 1 million lines makes a full table scan

    Hi Experts,

    I'm on Oracle 11.2.0.3 on Linux. I have a sql that inserts data into a table of History/Archives of a table main application based on the date. The application table has 3 million lines. and all the lines that are more then 6 months old must go in a table of History/Archives. This was decided recently, and we have 1 million rows that meet this criterion. This insertion in table archive takes about 3 minutes. Plan of the explain command shows a full table scan on the main Board - which is the right thing, because we are pulling 1 million rows in the main table in the history table.

    My question is that, is it possible that I can do this sql go faster?

    Here's the query plan (I changed the names of table etc.)

       INSERT INTO EMP_ARCH
   SELECT *
FROM EMP M
where HIRE_date < (sysdate - :v_num_days);

    I heard that there is a way to use opt_param tip to increase the multiblock read County but did not work for me... I will be grateful for suggestions on this. can collections and this changing in pl/sql also make it faster?

    Thank you

    (1) create an index on hire_date

    (2) tip 'additional' use in the 'select' query '

    (3) run ' alter session parallel DML'; before you run the entire statement

  • Dynamic SQL insert and dbms_sql.last_row_count

    I write a procedure which takes a variable number of parameters, and fills a global temporary table with the results if a dynamic query. I want to know how many lines is in the TWG after insertion, made using dbms_sql.execute. With the help of dbms_sql.last_row_count seems to work, but the documentation: said http://docs.oracle.com/cd/E11882_01/appdev.112/e25788/d_sql.htm#i1026354 'call this function after a FETCH_ROWS or an EXECUTE_AND_FETCH called. If called after a call to EXECUTE, then the returned value is zero.

    A much simplified test case is:
     
CREATE GLOBAL temporary TABLE bc_test_gtt 
  (col1 NUMBER(1)) 
ON COMMIT DELETE ROWS; 

DECLARE 
  nSqlCursor PLS_INTEGER; 
  nReturn    PLS_INTEGER; 
  sSql       VARCHAR2(100); 
BEGIN 
  sSql := 'INSERT INTO bc_test_gtt SELECT 1 FROM dual'; 
  nSqlCursor := dbms_sql.open_cursor; 

  dbms_sql.parse 
    (nSqlCursor 
    ,sSql 
    ,dbms_sql.native 
    ); 
     
  nReturn := dbms_sql.execute(nSqlCursor); 
   
  dbms_output.put_line(TO_CHAR(dbms_sql.last_row_count)||' last_row_count rows'); 
  dbms_output.put_line(TO_CHAR(SQL%ROWCOUNT)||' sql%rowcount rows'); 

  dbms_sql.close_cursor(nSqlCursor); 
END; 
/

sql%rowcount rows

    I would like to know if it is OK to use last_row_count in this scenario? His behavior would change in the future, leading to misleading results. Because of the doubts I have I might have just to SELECT COUNT (*) from bc_test_gtt; to get my result, but which seems to be an unnecessary use of SQL

    Background: I store a copy of the contact information in a denormalised, cleaned of structure. When a user enters a new client in the request, my procedure will return duplicates potential, based on the contact information that the user entered.

    Certainly, the documentation last_row_count should not be used after execution. So probably not safe to rely on this behavior.

    But the docs for run statement said:

    >
    This function executes a given cursor. This function accepts the ID number of the cursor and returns the number of rows processed. The return value is only valid for statements INSERT, UPDATE, and DELETE; for other types of statements, including the DDL, the return value is undefined and should be ignored.
    ...
    Returns the number of rows processed
    >

    And it's the package specification:

      function execute(c in integer) return integer;
  --  Execute the given cursor and return the number of rows processed
  --  (valid and meaningful only for INSERT, DELETE or UPDATE statements;
  --  for other types of statements, the return value is undefined and
  --  should be ignored).
  --  Input parameters:
  --    c
  --      Cursor id number of the cursor to execute.
  --  Return value:
  --    Number of rows processed if the statement in the cursor is
  --    either an INSERT, DELETE or UPDATE statement or undefined otherwise.
  --

    So it should be documented that you can simply use the value of nReturn ;-)

    I'm trying to update a table based on a backup action by the following code in the page that discusses the section. The code is executed 'On submit - after calculations and Validations'. When you click on save, it will not refresh the table.

    If the "Save" button submits the page and your process is set up to take when you press button = RECORD, so there is not much left to guess.

    Is the process created in a process of PL/SQL and it is on fire after calculations and Validations? Asuming it is true:

    You can cut and paste the section of the newspaper of debugging, where the process is listed and jumped?

    Can else you copy your page at apex.oracle.com and indicate the workspace name and identifiers?
