Export of DataPump API - number of rows exported using

Hello

I'm working on the procedure to export data in the table before deleting the partition. It will be run by the Scheduler of the data, that's why I want to run the datapump job using the API.

I wonder, if it is possible to get the number of rows exported. I would compare with the number of rows in a partition before you delete the partition.


Thank you

Krystian

Hello

Don't know exactly how you want the number of rows per partition that have been exported, but here are a few ideas:

1. create a log file by using 'add_file ':

-Add a log file

dbms_datapump.add_file (h, ' DEPTJOB.log ', a', NULL,)

dbms_datapump.Ku$ _file_type_log_file);

It is also in my example included below.  Here is the content after the DEPTJOB.log workload (situated in Oracle Directory object would be "in my example):

$ cat /tmp/DEPTJOB.log

Departure 'SCOTT '. "" DEPTJOB ":

Object type TABLE_EXPORT/TABLE/TABLE processing

Processing object type TABLE_EXPORT/TABLE/TABLE_DATA

. . "exported"SCOTT" DEPT': 'SYS_P1581' 5,929 KB 2 lines

. . "exported"SCOTT" DEPT': 'SYS_P1582' 5,914 KB 1 lines

. . "exported"SCOTT" DEPT': 'SYS_P1583' 5,906 KB 1 lines

Table main 'SCOTT '. "' DEPTJOB ' properly load/unloaded

******************************************************************************

Empty the files together for SCOTT. DEPTJOB is:

/tmp/Dept.dmp

Job 'SCOTT '. "" DEPTJOB "managed to 00:00

You can then review or extract the information from the log file.

2. save the master table and the query for the busy lines.

Use the parameter "KEEP_MASTER":

-Keep the main table to be deleted after employment ends

dbms_datapump.set_parameter(h,'KEEP_MASTER',1);

Here's my example, the request to the main table is at the end.

$ sqlplus scott/tiger @deptapi

  • Calculation of the number of rows in the query object

    Hi all
    I have a question:

    Is there a way to get the number of rows in a query object without running it twice?
    I need this for a calculation of total pages.
    I can't do something like:
    "SELECT COUNT (e) FROM employee e"
    because I have a WHERE clause in my expression.

    Thank you

    I don't think I've had this a simple that you would like to, but I was able to reuse the same query named to account real pagination queries request.

    I defined a named query:

            @NamedQuery(name = "Employee.findByNames", query = "select e from Employee e WHERE e.firstName LIKE :FNAME AND e.lastName LIKE :LNAME AND e.gender = :GENDER ORDER BY e.lastName, e.firstName")
    

    Now in the app, I can create an instance of the query for this named query and fill in the parameters using the:

            Query query = em.createNamedQuery("Employee.findByNames");
            query.setParameter("FNAME", "%");
            query.setParameter("LNAME", "%");
            query.setParameter("GENDER", "M");
    

    If I run this query I get all the lines, but instead, I'd like to create an account using the underlying native API query

            ReadAllQuery raq = JpaHelper.getReadAllQuery(query);
            ReportQuery reportQuery = new ReportQuery(raq.getReferenceClass(), new ExpressionBuilder());
            reportQuery.setSelectionCriteria(raq.getSelectionCriteria());
            reportQuery.setOrderByExpressions(raq.getOrderByExpressions());
            reportQuery.setShouldReturnSingleValue(true);
            reportQuery.addCount();
            Query countQuery = JpaHelper.createQuery(reportQuery, em);
    
            countQuery.setParameter("FNAME", "%");
            countQuery.setParameter("LNAME", "%");
            countQuery.setParameter("GENDER", "M");
    
            int count = ((Number)countQuery.getSingleResult()).intValue();
    

    Then, for each page of entities wanted the original query is executed as:

            query.setFirstResult(0);
            query.setMaxResults(5);
            List emps = query.getResultList();

  • How to determine the number of rows in the database and save the result to a local variable?

    Hello

    I'm a newbie in the use of TestStand, databases and SQL, and now I've met difficulties. I use TestStand 2014 (32 bit).

    I have a need to know the number of rows in a database and save that number in a local variable. I tried to practice using the database of the Types of step provided with TS. I tried to use the following in a SQL statement:

    Locals.NumberOfRows = ("SELECT COUNT (*) FROM TEST_TABLE")

    It returns an error: specified value is not the expected type. My goal is possible in this way, or I'm doing this completely wrong?

    -RautSa

    Thank you for your response, Norbert. I have a database of who wins new values at random, and sometimes I need the exact number of rows in this table.

    I managed to achieve my goal by using the SQL statement: "SELECT COUNT (*) as Rowcount OF TEST_TABLE", followed by a data GET operation, which records that number of lines in a local variable.

    For that you would benefit from the APEX$ ROW_STATUS integrated substitution string.

    1. create a page element display only (in my case P15_UPDATED_ROWS) Save Session State set to Yes and the Type of Condition is set to never.

    2. Add a calculation after the shows with a Type of static assignment and calculation value 0 to reset the counter whenever the page is sent.

    3. Add an On submit - after calculations and Validations process of PL/SQL page linked to your tabular presentation with a Status of Type PL/SQL Expression and Expression 1 :apex$row_status = 'U' and the code of the following process :

    :p15_updated_rows := :p15_updated_rows + 1;
    

    If you don't actually means "day" in the strict sense, and then change the status of process to include possible APEX$ ROW_STATUS 'C', 'U', and "D" values as needed. If you want to count all created, updated and deleted lines, do not add the condition to the process, but make sure the extended run is set to createand changed lines.

  • Number of rows in each partition is displayed with a NULL value for a table partitioned in user_tab_partitions. Why?

    I created a table and partitioned on the date of the entry and added a local partitioned index.

    Now, I use a query to extract "num_rows" of user_tab_partitions to know the number of rows in each partition.

    Getting this value as null num_rows, wonder why?

    After looking to explain the Plan after interrogation ("select * from my_table1 where entry_date = 1 January 2015" ;))

    to find out if she actually partitioned table and its data in different partitions, I interpreted in effect because the query plan had a line like Partition_range (Single).

    My Question is:

    (a) is actually partitioned data (have I misinterpreted the Explain plan)

    (b) why is the num_rows null column in the query (Pasted below)

    (c) also in addition what difference it would have been if I had created a Global Index instead of the Local Index in my case?

    The following code Snippet:

    ----------------------------------------------------------------------------------------------

    create the table my_table1
    (
    roll_no number constraint my_table1_pk primary key,
    date of entry_date
    )
    partition of range (entry_date)
    (
    PARTITION data_p1 VALUES LESS THAN (TO_DATE (December 31, 2014 ',' DD-MM-YYYY ""));
    PARTITION data_p2 VALUES LESS THAN (MAXVALUE)
    );


    create an index only my_table1_indx on my_table1 (entry_date) local;

    ----------------------------------------------------------------------------------------------

    I now insert two lines:
    insert into my_table1 values (1, to_date ('01-01-2015', ' dd-mm-yyyy'));
    insert into my_table1 values (2, to_date('01-02-2015','dd-mm-yyyy'));

    ----------------------------------------------------------------------------------------------

    These have been inserted successfully, now using the query below shows num_rows column as null. I don't know why?

    SELECT table_name, num_rows, high_value, nom_partition
    Of user_tab_partitions
    where table_name = 'MY_TABLE1 '.
    ORDER BY table_name, nom_partition;

    ----------------------------------------------------------------------------------------------


    (a) is actually partitioned data (have I misinterpreted the Explain plan)

    Yes, it is partitioned. You can query this particular partition SELECT * FROM my_table1 (data_p1) PARTITION to check that.

    (b) why is the num_rows null column in the query (Pasted below)

    As already mentioned that you have not collected statistics.

    (c) also in addition what difference it would have been if I had created a Global Index instead of the Local Index in my case?

    In fact, you have created two types of indexes without knowing (can be)! One is not partitioned (although this column is not partition key) and another is partitioned (LOCAL). They are MY_TABLE1_PK and MY_TABLE1_INDX. You can check that USER_INDEXES.

    You can read this article to get an early jump on the partitioning of decision. Partition: Partition decisions

    ${ORACLE_HOME}/bin/sqlplus -L >> ${LOG_FILE} 2>&1  << EOF
      ${ORAID}/${ORAPASS}@${ORAINS}
      whenever sqlerror exit sql.sqlcode;
      set echo on;
      set feedback off;
      set serveroutput on;
      @${SQL_FILE};
      exit;
    EOF
    RC=$?
    

    The SQL_FILE of entry content is:

    select 12 "col1" from dual;
    select 'abcd' "col2" from dual;
    select;
    select 13 'col3' from dual;
    

    The result of the race of sqlplus is (LOG_FILE):

    You will need to export mpeg2-DVD and then take it to a creation as a supplement program to create a DVD compatible file.

  • number of rows fetch are not even

    Hi all


    I'm new to sql/plsql

    Oracle version 11R2
    RHL 5.0 OS


    I'm deleting all rows in the parent table as well as children tables based on some criteria to date.

    the parent BE_STATUS table contains a column OOC_DT. based on the OOC_DT I get BE_STATUSin the parent Table rows.

    other children tables DOES NOT have OOCDT column but meet BENo. and BEDT WHO are also in PARENT TABLE BESTATUS.


    So I get all the be_no, * be_dt * of BE_STATUS based on the OOC_DT column as below
    select distinct(count(*)) from be_status where ooc_dt between '31-mar-10' AND '24-dec-10';
    
    (COUNT(*))
    ----------
     65074 
    and I create a temporary table based on the above query as
    create table temp as select be_no, be_dt from be_status where ooc_dt between '31-mar-10' AND '24-dec-10';
    table created.
    and then I count the number of rows in the temporary table
    select distinct(count(*)) from temp;
    (COUNT(*))
    ----------
     65074 
    so there are around 51 children tables that have the BE_NO AND BE_DTcolumn.

    If the total number of lines in the temp must be equal to the total of all the lines in each column according to the above criteria.

    It's
    select distinct(count(*)) from be_penal  where (be_no,be_dt) in (select be_no,be_dt from temp);
    (COUNT(*))
    ----------
            64 
    
    select distinct(count(*)) from be_fine  where (be_no,be_dt) in (select be_no,be_dt from temp);
    
    (COUNT(*))
    ----------
            62
     
    select distinct(count(*)) from be_cash_lic  where (be_no,be_dt) in (select be_no,be_dt from temp);
    (COUNT(*))
    ----------
            23 
    
    select distinct(count(*)) from c_cl_be  where (be_no,be_dt) in (select be_no,be_dt from temp);
    (COUNT(*))
    ----------
             2 
    select distinct(count(*)) from chex where (be_no,be_dt) in (select be_no,be_dt from temp);
    (COUNT(*))
    ----------
             0 
    select distinct(count(*)) from amend_q where (be_no,be_dt) in (select be_no,be_dt from temp);
    (COUNT(*))
    ----------
             0 
    
    select distinct(count(*)) from be_perm  where (be_no,be_dt) in (select be_no,be_dt from temp);
    (COUNT(*))
    ----------
           889 
    select distinct(count(*)) from exam_instr where (be_no,be_dt) in (select be_no,be_dt from temp);
    (COUNT(*))
    ----------
           690
    
    select distinct(count(*)) from c_rms_mesg  where (be_no,be_dt) in (select be_no,be_dt from temp);
    (COUNT(*))
    ----------
         64982
    
    select distinct(count(*)) from item_duty_fg  where (be_no,be_dt) in (select be_no,be_dt from temp);
    (COUNT(*))
    ----------
        398129 
    
    select distinct(count(*)) from a_item_det  where (be_no,be_dt) in (select be_no,be_dt from temp);
    (COUNT(*))
    ----------
         31453
    select distinct(count(*)) from item_det  where (be_no,be_dt) in (select be_no,be_dt FROM temp);
    (COUNT(*))
    ----------
        622271
    so, as you can see the TEMP TABLE contains only * 65074 *. Therefore the sum of the numbers of all of the above tables should be * 65074 * but only item_det contains
    * 622271 * lines.


    I have made a mistake in counting the records individually?

    waiting for your helpful answer

    Thanks and greetings

    Not quite sure, I followed your question, but a glaring fault in your codes...

    between '31-mar-10' AND '24-dec-10';
    

    dates should be treated as dates, not the chains and left us 2 years of numbers of programming standards waaay back in the 90's when everyone fixed these issues in the context of the challenges of the Millennium bug.

    between to_date('31-mar-2010','DD-MON-YYYY') AND to_date('24-dec-2010','DD-MON-YYYY');
    
  • Displays the number of rows in the table displaying a named criteria query data

    I created a test named for my View, called 'Criteria1' and Criteria1 to create a group of ADF with Table query. I want to display the number of rows in result when a search is performed. How can I do?

    Thanks in advance,
    Tom

    As mentioned, you can add outputText and you must give OutputText partialTriggers as query component your Id. Thus, when you give a search on the query component, it will refresh the outputText with the number of lines.


    ID = "ot1" partialTriggers = "id of the component of motion here" / > ""
