• Control files - delete records before insert

  Hello
  
  I have a file of control as follows:
  
  DOWNLOAD THE DATA
  INFILE 'PRODUCT_DESC*.txt '.
  ADD
  IN THE TABLE PROD_DESC
  WHEN (1:4), <>' 00 |' and <>(1:3) 99 |' and (1:3) <>' | »
  FIELDS TERMINATED BY ' |'
  TRAILING NULLCOLS
  (
  PARTNUMBER,
  PRODUCTNAME,
  SERVICEIDLABEL,
  SORTSEQUENCE)
  
  When my control file is executed, I would replace the records existing in the table to the records in the file if PARTNUMBER in the file is the same as the table. If this isn't the case, it will just add on the record in the table.
  
  Here is how the logic goes:
  
  IF ((PARTNUMBER dans l'enregistrement dele de fichier) = (PARTNUMBER in table PROD_DESC)) THEN
  Replace the record in the table with the record in the file
  ON THE OTHER
  Add the file to the table
  END IF
  
  How am I suppose to change my CONTROL file for this logic?

• Confirm delete before inserting then have a unique key.

  Hello

  I have a use case where a database field that is entered by the user must be unique.

  In the database, there is already a record for example 'name1 '.

  The user inserts a new record and puts his name 'name1' as well. Then, for some reason any decides to delete the first existing record and tries to save the new record 'name1 '.

  The previous record validation "Name1" is not yet removed, but the new record with 'name1' seeks to insert.

  Then I get the error message: attribute value 'name1' leads to duplicate keys for this type of entity. oracle.jbo.AttrValException...

  Is it possible to run delete before insertion on commit or another work around?

  Is there a parent-child relationship between the tables involved in the triggering event? Is there a foreign key used above the child table that references the parent table?

  If you have a parent-child relationship and a trigger on the parent table must be running some DML on the child table, and, if the child table as a foreign key (FK) back to the parent table, any DML on the child table will cause a recursive SQL statement to check the constraint. Indirectly, this will cause an exception table mutation.

  So watch the dependencies on SOR_O_HISTORY / FS_TEST_HISTORY/all other related table. A FOREIGN KEY can make it to mutate (no pun intended).

  Hope this will help you find the root cause.

  Hello

  to use a column in a trigger, the column must have: new for new values, or: old old values before the name of the column, so your if statement should begin with:

  IF :NEW.STA_STARTDATE

• Why delete the temporary file?

  Why delete the temporary file?

  because temporary files are of no use to us and toff are created for temporary use so after use keep them in our system, as resulting from the decreade of memory hard drive and also a lot of downturns and vaults of virus, so it is better to delete the temporary files u can try one of them to make the best management of your temporary folder

  1. search for folder or folder type in the run command and delete everything in the temp folder
  2.u can also use tune up utilities software

• Truncate a field before inserting

  Suppose I have the following text:

  Array: mytable

  field: username (VARCHAR2 (35))

  field: zip (VARCHAR2 (5))

  I am importing data from an excel with columns username and zip file. A couple of the usernames contains more than 35 characters, and some postal codes are in the format xxxx-xxxxx, therefore containing more than 5 characters.

  I tried to write an insert before truncating the data until they are inserted. For any user name that is longer than 35 characters in Excel, simply truncate the username to the first of 35 characters. Similarly, for any ZIP code which is above 5 characters, just truncate the zip on the first 5 characters.

  The trigger for postal codes:

  CREATE OR REPLACE

  Trigger_zipc RELAXATION

  BEFORE INSERTING

  ON mytable

  FOR EACH LINE

  BEGIN

  SELECT substr (: new .zip, 1, 5)

  IN: new.zip

  Double;

  END;

  However, I get the error: ORA-12899: value too large for column

  I understand that this happens because the value is read before my validation, and because the value is too large, it is not allowed to insert.

  I'm not sure where to go from here. Any suggestions?

  Is it excel file or a csv file.

  I think you can look into creating an external table as well.

  Before inserting it just to make a substring.

  Something along the lines.

  CREATE TABLE ext_data (
   username CHAR(500),
    zip CHAR(500))
    ORGANIZATION EXTERNAL (TYPE ORACLE_LOADER DEFAULT DIRECTORY ext_tab_dir
    ACCESS PARAMETERS (FIELDS TERMINATED BY ',')
    LOCATION ('csv.dat'));
  
  insert into mytable
  select substr(username,1,35) , substr(zip,1,5) from ext_data;
  

  I hope this helps.

• Why the index are lost after recovering from a REPLICATE_PERSISTENT region?

  GemFire Version V7.0.1.3 for region below specifications. java.lang.String com.foo.bar.Positon after recovery of the store persistent it is no markings on the region. All indexes are lost. CacheFactory cacheFactory = new CacheFactory(); cache = cacheFactory.create (); Ins ByteArrayInputStream = new ByteArrayInputStream (cachexmlstring); cache.loadCacheXml (ins);

  OK I understood why the index get lost. Is that the way cache is initialized.

  CacheFactory cacheFactory = new CacheFactory();

  cache = cacheFactory.create (); Cache is created here without consideration of persistence pdx

  Ins ByteArrayInputStream = new ByteArrayInputStream (cachexmlstring);

  cache.loadCacheXml (ins); Now loading data it has no definition pdx index data.

  So now even if I get the data loaded in the regions, when I probe through gfsh, there's no index.

  I just changed the code of

  FileOutputStream ops = new FileOutputStream ("cache.xml");

  OPS. Write (cachexmlstring. GetBytes());

  CacheFactory cacheFactory = new CacheFactory();

  cache = cacheFactory.create ();

  The indexes are coming fine...

• Why bitmp index are not suggested for DML operations

  Hi all
  
  Can someone make me understand why bitmap indexes are not suggested to use for DML operations. AFAIK, the reason being that it locks the table and another user won '; t be able to complete the transaction but why?

  user13389425 wrote:
  the reason is that I found is that it stores the rowid of beginning and the end rowid and the value of the spreadsheet store n number of entries of the inder, so any operation DML whole leaves lock themselves and cause the performance of the database. My next question I was not able to address, is that the index entries how do I store it on a single sheet. How calcualte the same.

  It is not the entire sheet that gets locked, just the specific index entry in the block sheet index, as well as the corresponding lines in the table referenced by the rowid ranges in the index entry.

  As an indication, the average number of index entries in a block of sheets is the num_rows/leaf_blocks in dba_indexes. As an example, the average number of rows in the table referenced by the index entry is (num_rows in dba_tables/num_rows in dba_indexes) * distinct_keys in dba_indexes.

• Helps relaxation that fits into another table before insertion

  I have two tables:
  
  TABLE A as follows:
  x, y, z
  1, 1, 1
  1, 1, 2
  1, 1, 3
  
  TABLE B as follows
  c, d, e, f
  1, 1, 1, 8
  1, 1, 1, 2
  1, 1, 1, 6
  1, 1, 2, 5
  1, 1, 2, 10
  1, 1, 2, 3
  1, 1, 3, 12
  1, 1, 3, 11
  1, 1, 3, 15
  
  
  I want a trigger, BEFORE insertion in the TABLE B, I want to INSERT into TABLE A as follows:
  
  c = > x
  d = > y
  e = > z
  
  ONLY IF a (x, y, z) record does not already exist in the TABLE.
  
  That is to say. If record (1, 1, 3) already exists in the TABLE, we do not try to put it back when you insert in the TABLE B with values containing (1, 1, 3).

  You will need

  CREATE OR REPLACE trig_on_insert
  BEFORE INSERT ON B
  FOR EACH ROW
  IS
     lv_count    NUMBER := 0;
  BEGIN
     SELECT COUNT(1)
       INTO lv_count
       FROM a
      WHERE x = :new.c
        AND y = :new.d
        AND z = :new.e ;
  
     IF ( lv_count = 0 ) THEN
        INSERT INTO A VALUES(:new.c,:new.d ,:new.e);
     END IF;
  END;

• Redirect data to another table using before insert trigger.

  Dear all,
  How can I redirect the data to another table in a before Insert trigger? My database is Oracle10g.
  I have a table EMP (EMP_ID, LAST_NAME, SALARY).
  I have another EMP_COPY table with the same structure. I also have a before Insert trigger on the EMP table.
  Based on a condition that I have to redirect the data in table EMP_COPY. Let's say the condition is EMP_ID = 100.
  I fire an insert on EMP table for example INSERT IN EMP(EMP_ID,LAST_NAME,SALARY) VALUES(100,'Dev',500).
  On the inside of the front Insert trigger on the EMP table, I have the code
  IF EMP_ID = 100 THEN
  INSERT INTO EMP_COPY (EMP_ID, LAST_NAME, SALARY)
  VALUES(:NEW.) EMP_ID,: NEW. LAST_NAME,: NEW. SALARY);
  COMMIT;
  ON THE OTHER
  NULL;
  END IF;
  But the problem here is that data goes to EMP table of origin also although I don't want. He should do an Insert into EMP table only if EMP_ID! = 100.
  
  One way has been to raise a user-defined exception inside the If statement and not handle it so that the original insert on table EMP fails but INSERT comes in the EMP_COPY table. But in this solution since the inside the trigger unhandled exception, it propagates to the calling environment. And I can't stand outside relaxation as the calling environment is a form of Oracle Apps standard that cannot be customized.
  
  Any kind of help will be highly appreciated that I am fighting for more than two weeks.
  
  Thanks in advance
