PL/SQL cursor help

Dear Experts,

I need help, writing / editing PL/SQL procedure below. My task is to rebuild indexes on tables that were not rebuilt during the last 24 hours. The "select" statement of down gives me the list of all the names of tables whose indexes are not rebuilt in last 24 hours (maint.index_rebuild is a custom table, we built to capture the rebuild index timings).

maint.online_reorg procedure done index rebuild. I need this procedure to run on all tables (returned by the select statement). How can I get the modified procedure to get what I'm looking for below. Enjoy your entries.

declare cursor c1 is
select distinct table_name from maint.index_rebuild where start_time <= SYSDATE-1;
begin
for i in c1 loop
maint.online_reorg('OWNER','table name from cursor result set');
end loop;
end;
/
declare
  cursor c1 is
    select distinct table_name from maint.index_rebuild where start_time <= SYSDATE-1;
begin
  for i in c1 loop
    maint.online_reorg('OWNER',i.table_name);
  end loop;
end;

will do what you ask. As others have pointed out, however, what you're trying to do is strongly discouraged. Reconstruction of each index everyday is going to generate a huge amount of load on your database for no benefit and creates a number of opportunities to introduce errors.

  • Parsing sql - cursor parent and child

    Hi all

    What is the parent and child when parsing sql cursor?

    Thank you

    John

    Well, as Anand mentioned you could yourself. Here's a demo of the workaround based. Based on the change of environment, the sliders would be created and will not be shared that I made using the change of parameter of optimizer_mode. This is done in 11201 with the setting optimizer_features_enable on 10201.

  • REF cursor in sql dynamic help to run immediately

    Hello

    How can we get the Ref cursor out a dynamic sql statement by executing immediate proceedings
    for example, immediately run ' open CROR for select * from dynamicTable'

    in this area, CROR is a dynamic cursor and table name is dynamic (known at run time), and we can't write static sql statement.

    Thank you

    I don't know what exactly you are after but here is a sample of what can be done.

    SQL> VAR r REFCURSOR;
SQL> BEGIN
  2          OPEN :r FOR 'SELECT * FROM DUAL';
  3  END;
  4  /

PL/SQL procedure successfully completed.

SQL> PRINT r

    You can use the OPEN... FOR education with a dynamic string.

  • The adaptation and Pl/SQL cursor sharing

    Hello

    I have this database:

    NLSRTL11.2.0.1.0Production
    Oracle Database 11g Enterprise Edition11.2.0.1.064 bit Production
    PL/SQL11.2.0.1.0Production
    AMT for Solaris:11.2.0.1.0Production

    I'm testing the queries and adaptive cursor sharing. I have a table T1 that is created by selecting all object. It has additional is NOT NULL ID of the column that is PK and is filled through sequence. It has a regular index (OBJECT_TYPE, OBJECT_NAME). Statistics are collected on the T1 table and its indexes.

    Total of T1 lines and are 1065951.

    I have run this test in SqlPlus:

    ID of the VARIABLE NUMBER;

    EXECUTE: id: = 10;

    SELECT COUNT (*) FROM t1 WHERE id <: id;

    So I check the instruction in v$ sql and the execution plan and I can see that the plan is:

    SQL_ID, 3m2qaytqgk9jt, number of children 0

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

    Select COUNT (*) from t1 where id <: id

    As we can see it Adaptive cursor sharing has been used and in both cases the appropriate execution plan has been used.

    When I run test with PL/SQL block, however, I don't see the use of extended cursor sharing. Could you please help understand why?

    The test is (I used deliberately < = in order to create the new parent cursor):

    DECLARE

    PID NUMBER;

    CNT PLS_INTEGER;

    BEGIN

    BECAUSE me in 1... 10 LOOP

    IF i IN (2, 4, 6, 10) THEN

    PID: = round (dbms_random.value (1, 5000));

    ON THE OTHER

    PID: = round ((100000, 1600000) dbms_random.value);

    END IF;

    dbms_output.put_line ('ID: ' | pid);

    COUNT (*) of SELECT INTO cnt FROM t1 WHERE id < = pid;

    END LOOP;

    END;

    /

    Output of this is:

    ID: 396582

    ID: 2584

    ID: 560405

    ID: 3275

    ID: 827442

    ID: 4515

    ID: 167771

    ID: 652411

    ID: 512147

    ID: 230

    As we can see some ID values are good candidates for INDEX BEACH, others are for the INDEX FAST FULL SCAN. However, I am only a child cursor for my parents:

    SQL > SELECT sql_id, child_number, executions, 'IS_BIND_SENSITIVE', 'IS_BIND_AWARE', 'IS_SHAREABLE' OF V$ SQL WHERE SQL_ID = "6xh03mm87nmu3";

    THE EXECUTIONS OF CHILD_NUMBER SQL_ID I I I

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

    0 10 6xh03mm87nmu3 Y N Y

    SQL >

    Please pay attention to the value for IS_BIND_AWARE, who is with my first child 0. So no other children were created. Why in PL/SQL, it behaves differently and how can we enjoy the cursor of adaptation in this context?

    Thank you!

    My immediate thoughts were under cover PLSQL optimizations.

    PLSQL_OPTIMIZE_LEVEL has no effect.

    To run I had to Board BIND_AWARE and SESSION_CACHED_CURSORS value 0.

    Subsequently found Randolf Geist post in the same direction:

  • PL/SQL cursors: definition and purpose

    How are you?

    I wanted to ask the following question:
    What is the exact definition of a "slider"? of course, it is not equivalent to a pointer in C/C++.

    also, why can not simply RETRIEVE us the data in a RECORD without a slider? in other words, what is the point of a 'slider '?

    Obviously, there is a specific purpose of cursors in PL/SQL language, I just wanted to know what it is. The book that I use does not explain the two issues I have just raised.


    Thank you :)

    In PL/SQL, generally, using variables, you would store stores unique values and can be used for processing later. You would use a SELECT - CLAUSE to extract the required of the database value and store it in your variable. If the SELECT query is extraction of several columns, you would use a different variable for each column name.

    But what to do when your SELECT query returns many rows? And your need is to treat each line in a loop one after the other?

    One solution is to use the sliders (are there others too). Cursors provide a way by which you can run a query that returns multiple records and then loop through the cursor to treat each one record after another.

    In addition, if you worked on any application front end (say J2EE), also would you use cursors (called REFCURSORs in this case) to return the result of the whole (including multiple records) request as a result set. The calling (in this case - a DAO) program loops through the ResultSet and treats each unique record sequentially.

    Personally, I use the sliders in another case - even when the query returns a single row. If I have to go get a big no. (even if only a row) columns in my SELECT query, then I go for a CURSOR, instead of declaring each individual value. In this way, I avoid all of these statements and my code is as compact as it can get. Here's how to use it...

    Report separately the individual values

    declare
   l_val1  my_table.val1%type;
   l_val2  my_table.val2%type;
   l_val3  my_table.val3%type;
   ...
   l_valn  my_table.valn%type;

begin
...
   select val1, val2, val3, ... valn
   into   l_val1, l_val2, l_val3, ... l_valn
   from   my_table
   where  <>;

   if ((val1 = val2) or (val3 = val4))
   then
      ...
   end if;
end;

    And it's the same thing with the CURSOR

    declare
   cursor l_cur is
      select val1, val2, val3, ... valn
      from   my_table
      where  <>;
begin
   for rec in l_cur
   loop
      if ((rec.val1 = rec.val2) or (rec.val3 = rec.valn)
      then
         ...
      end if;
   end loop;
end;

    You would see that even in this demo, I saved 5 lines!

    I hope this helps!

    Hi all

    I tried to use Dense_rank as below. But it gives me the top selling books. I need high library in each type...

    This looks like a job for 'PARTITION BY type

    For example:

    WITH got_rnk AS

    (

    SELECT b.bid, b.type

    SUM (o.quantity) AS total_quantity

    DENSE_RANK () OVER ( PARTITION BY b.type

    ORDER OF SUM (o.quantity) / / DESC

    ) AS rnk

    B BOOK

    o order1

    WHERE b.bid = o.bid

    GROUP BY b.bid, b.type

    )

    SELECT total_quantity, type submission

    OF got_rnk

    WHERE rnk = 1

    ;

    . Aggregate functions (such as the SUM, above) are calculated before analytical functions, so an analytic function (such as DENSE_RANK above) may depend on an aggregate function; you don't need a separate subquery for that.

    Most of the questions I resolved or can live with, but is not one of these.

    In my image, the circle at the bottom has a selection rectangle (which is supposed to be my brush cursor, but when I screen cap it disappears) indicating the size of the cursor, but the cleared area is significantly greater than the slider. I messed up round in 'Sliders' options, but none of those who have had no effect.Untitled-.png

    I'll try to be as helpful as possible as well as to answer the questions.

  • SQL - select Help - box When? Return value of the second Table?

    -Next to people on this forum I am probably somewhere between a beginner and an intermediate SQL user.

    Ive been using a case when stated in plsql to find "all who has status in any program was canceled during a specific time, but have become or are still active in another program"

    So, Im actually trying to return a value from another table in a case where, but this isn't anthing taste other than a text declared as 'Yes' or 'no '.

    This is the select statement - y at - it another way to do it where I can get the results I need?

    -case when pp.party_id in (select pp1.party_id - cancelled active clients in another program)

    of asa.program_participation pp1,.

    ASA.curr_prog_participation_status cpps1

    where pp1.program_participation_id = cpps1.program_participation_id

    and pp1.party_id = pp.party_id

    and cpps1.code_value = 'Act')

    So 'Yes' is still 'No' end as Active_in_Other_Prg

    So - instead of 'Yes', I want essentially the program they are active or pp1.program_id, another null

    It is possible that the client can be active in more than one program as well.

    Any help is greatly appreciated, I explored with if and decodes but I can't get anything to work.

    Ben

    Looks like an outer join. See doc ora: joins at

    Select p

    q.party_id

    q.program_id

    of table_with_party_id p

    , (select pp1.party_id - cancelled active clients in another program)

    pp1.program_id

    of asa.program_participation pp1,.

    ASA.curr_prog_participation_status cpps1

    where pp1.program_participation_id = cpps1.program_participation_id

    and pp1.party_id = pp.party_id

    and cpps1.code_value = 'ACT') q

    where p.party_id = q.party_id (+)

    Note: In the example above shoudn't it be a space between the (and +), but the forum software automatically converts to

    The outer join will connect display all records in the table p and q records only if fits the party_id, IE q.party_id and q.program_id will be null if there is no match.

    I just tested this in my SYS schema (although you should not create objects in SYS.)  and got...

    Not sure why it's up the DML operation... which seems inner exception to the dbms_space package.  Even if I just run it directly in sys like this:

  • SQL cursor problem

    Hi all

    I want to see the records in the table emp or a message if the emp table is empty, but under cursor shows the two,

    How can I solve this problem, please help.

    declare
    cursor emp_cur is
    Select * from emp;
    SheikYerbouti emp % rowtype;
    Start
    Open emp_cur;
    loop
    extract in SheikYerbouti emp_cur;
    If emp_cur % notfound then
    dbms_output.put_line ('there no record in the employee table');
    "exit";
    on the other
    dbms_output.put_line (emp_rec.empno |) » '|| emp_rec.ename);
    end if;
    end loop;
    close emp_cur;
    end;

    You should do something like this,

    not tested.

    DECLARE
   CURSOR emp_cur
   IS
      SELECT * FROM emp;

   emp_rec   emp%ROWTYPE;
   i         NUMBER := 0;
BEGIN

   IF emp_cur%ISOPEN THEN

      CLOSE emp_cur;

   END IF;

   OPEN emp_cur;

   LOOP

      FETCH emp_cur INTO emp_rec;

      EXIT WHEN emp_cur%NOTFOUND;

      i     := i + 1;

      DBMS_OUTPUT.PUT_LINE (emp_rec.empno || ' ' || emp_rec.ename);

   END LOOP;

   IF i = 0 THEN
      DBMS_OUTPUT.PUT_LINE ('There is no record in employee table ');
   END IF;

   CLOSE emp_cur;

END;

    Earlier you were printing that the records did not exist for when the extraction fails. Extraction fails at the end of the recording for any cursor. If you have found the two.
    Now, you print it out only if message I = 0, which means that the cursor did not return a single record.

    G.
