• How to truncate the table using SQLJ

  Here is a snippet of code SQLJ trying to truncate a table before filling with new records.
  
  However, while the class compiles fine, I get an error PLS-00103 on execution.
  
  Your expertise is very welcome and necessary for what seems like a simple problem, for which I can't find an answer.

  You must run a command DDL by NDS. If you wrap it in a PL/SQL block and use NDS to run it, it should work.

  
  
  BEGIN
  
  EXECUTE IMMEDIATE "DDL STATEMENT";
  
  END;

• Data export of the Disqualification to the table in step should not truncate the table.

  Hello friends,

  Please find blow my requirement and do the necessary.

  We export data cleaned to staging tables, whenever we export data, Disqualification truncates the table and inserts the new data sets into this table.

  My requirement is instead of truncating the table before inserting the data in it, Disqualification must add these records, should not truncate the table.

  Please let me know how to configure this in OEDQ, your help is appreciated.

  Thank you, Prasad

• Index rebuild required after truncate the table and load data

  Hello
  
  
  I have a situation that we truncate tables bit and then we loaded data [only content] on these tables. What you need to rebuild the index online is necessary or not?
  
  
  And another question is if we drop a few clues is the total amount of space is released or not. And re-create indexes will use the same amount of space. As I don't have disk space more? In this situation, rebuild the index online will be a better idea...
  
  Can you please on this...
  
  
  truncate the table some the few loading tables + reconstruction markings online is the best (or) droping little tables, a few tables loading + re-create the index is better
  
  Can you suggest the best way... We have a time that it currently we don't have enough space on the disk... [Option should not effect the space]

  user13095767 wrote:
  Ok. I have it...

  u want to say if we disbale the index while loading... Next, we need to spend the time to build.

  If the indexes are enabled, then rebuild again is not necessary after loading tables...

  Please answer if my understanding is correct...

  above is correct

  >

  If so, how abt the differences in the space occupied by the spaces of storage during the index rebuild and re-create... T he acquires more space if recreate us [deletion and creation] or rebuild online is preferable to an index...?

  space used is the same for all options.

  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).

• A question about the count of several lines of table in a PL/SQL block

  Hi all
  
  
  
  
  I have a problem on counting the rows from several tables in a PL/SQL block, and I would be grateful if you could kindly give me a helping hand. Here's my problem: file in Microsoft Excel (one column) I have a list of several names of tables. For each table, when the number of rows is equal to 10000 I have to call a procedure. Here's how I tried to do:
  

  DECLARE
       CURSOR tb_cursor IS
            WITH my_table_names AS
                 (
                      SELECT  'table1'  AS tbname  FROM  DUAL  UNION
                      SELECT  'table2'  AS tbname  FROM  DUAL  UNION
                      SELECT  'table3'  AS tbname  FROM  DUAL  UNION
                      SELECT  'table4'  AS tbname  FROM  DUAL  UNION
                      .
                      .  Here I continue writing one line for each table in order
                      .  to have the table names stored in my Excel file as a table 
                         to be queried by SELECT statement
                      .
                 )
            SELECT *
            FROM my_table_names;
  BEGIN
       -- Here I verify that for each table having more than 10000 lines
       -- I call the specified procedure which is needed
       
       FOR I IN tb_cursor LOOP
            DECLARE
                 -- Here I declare a cursor for counting the number of rows
                 CURSOR currentTableRowCounter IS
                      SELECT COUNT(*) AS rowsNum
                      FROM I.tbname;
                      
                 numberOfRows currentTableRowCounter%ROWTYPE;
            BEGIN
                 OPEN currentTableRowCounter;
                 FETCH numberOfRows INTO numberOfRows;
                 CLOSE currentTableRowCounter;
                 
                 IF (numberOfRows.rowsNum > 10000) THEN
                      -- And here I will call the procedure which has to be run
                 END IF;
            END;
       END LOOP;
  END;
  /

  I already checked this code with tables inividual and it works. The only problem is
  

  . . .
  SELECT COUNT(*) AS rowsNum
  FROM I.tbname;
  . . .

  Indeed, oracle considers "I.tbname" as an unknown table name (although he refers to by its exact name).

  SQL> @script.sql
  
                                  FROM I.tbname;
                                         *
  ERROR at line 99:
  ORA-06550: line 99, column 12:
  PL/SQL: ORA-00942: table or view does not exist

  How can I solve this problem? I mean, how to use a variable (in my example, I.tbname) as the table name in the FROM clause to query a table instead of explicitly write the name of the table?
  
  
  
  
  
  Thanks in advance,
  Dariyoosh

  Replace the following code:

            DECLARE
                 -- Here I declare a cursor for counting the number of rows
                 CURSOR currentTableRowCounter IS
                      SELECT COUNT(*) AS rowsNum
                      FROM I.tbname;
  
                 numberOfRows currentTableRowCounter%ROWTYPE;
            BEGIN
                 OPEN currentTableRowCounter;
                 FETCH numberOfRows INTO numberOfRows;
                 CLOSE currentTableRowCounter;
  
                 IF (numberOfRows.rowsNum > 10000) THEN
                      -- And here I will call the procedure which has to be run
                 END IF;
            END;
  

  By the following:

  Declare
    numberOfRows number;
  begin
    EXECUTE IMMEDIATE 'select count(*) from '||I.tbname into numberOfRows;
  
    IF (numberOfRows.rowsNum > 10000) THEN
      -- And here I will call the procedure which has to be run
    END IF;
  end;

  When you repost you must SHOW an example of what you are wanting to do. You should also explain what you mean by 'LONG Format' - I have never heard such a thing.
