• How to optimize the select query executed in a cursor for loop?

  Hi friends,
  
  I run the code below and clocked at the same time for each line of code using DBMS_PROFILER.

  CREATE OR REPLACE PROCEDURE TEST
  AS
     p_file_id              NUMBER                                   := 151;
     v_shipper_ind          ah_item.shipper_ind%TYPE;
     v_sales_reserve_ind    ah_item.special_sales_reserve_ind%TYPE;
     v_location_indicator   ah_item.exe_location_ind%TYPE;
  
     CURSOR activity_c
     IS
        SELECT *
          FROM ah_activity_internal
         WHERE status_id = 30
           AND file_id = p_file_id;
  BEGIN
     DBMS_PROFILER.start_profiler ('TEST');
  
     FOR rec IN activity_c
     LOOP
        SELECT DISTINCT shipper_ind, special_sales_reserve_ind, exe_location_ind
                   INTO v_shipper_ind, v_sales_reserve_ind, v_location_indicator
                   FROM ah_item --464000 rows in this table
                  WHERE item_id_edw IN (
                           SELECT item_id_edw
                             FROM ah_item_xref --700000 rows in this table
                            WHERE item_code_cust = rec.item_code_cust
                              AND facility_num IN (
                                     SELECT facility_code
                                       FROM ah_chain_div_facility --17 rows in this table
                                      WHERE chain_id = ah_internal_data_pkg.get_chain_id (p_file_id)
                                        AND div_id = (SELECT div_id
                                                        FROM ah_div --8 rows in this table 
                                                       WHERE division = rec.division)));
     END LOOP;
  
     DBMS_PROFILER.stop_profiler;
  EXCEPTION
     WHEN NO_DATA_FOUND
     THEN
        NULL;
     WHEN TOO_MANY_ROWS
     THEN
        NULL;
  END TEST;

  The SELECT inside the LOOP FOR cursor query took 773 seconds.
  I tried to use COLLECT in BULK instead of a cursor for loop, but it did not help.
  When I took the select query separately and executed with a value of the sample, and then he gave the results in a Flash of a second.
  
  All tables have primary key index.
  Any ideas what can be done to make this code more efficient?
  
  Thank you
  Raj.

  DECLARE
    v_chain_id ah_chain_div_facility.chain_id%TYPE := ah_internal_data_pkg.get_chain_id (p_file_id);

• as with the select query

  Hello

  I have a query something like...

  Select...

  ....

  where

  b.ProdName as 'GEAR of the TREE %' or b.prodname like '% FRONT GEAR %' or b.prodname like '% BREAK 4 %k '.

  and

  b.ProdName as

  (select the name of the society of companyms

  where < some comdition >

  )

  order of 3.6

  I have blocked in:

  b.ProdName as

  (select the name of the society of companyms

  where < some comdition >

  )

  How to give a select query with like operator.

  In above query I want to b.prodname as above and the name of the company for which I give condition.  Company names are stored in another table and I want to select and use them with like operator.

  Thank you.

  Hello

  It is not clear what you want to do.

  One possibility is an EXISTS subquery, like this:

  ...

  WHERE (b.prodname LIKE "% of the CYCLE of the TREE" - begins with this text

  OR b.prodname LIKE '% FRONT GEAR %' - contains this text

  OR b.prodname LIKE '% BREAK 4 %k' - contains this text

  )

  AND THERE ARE)

  SELECT 1

  OF companynms

  WHERE--a condition

  AND b.prodname AS business

  )

  I hope that answers your question.
  If not, post a small example of data (CREATE TABLE and only relevant columns, INSERT statements) for all of the tables involved and the results desired from these data.
  Explain, using specific examples, how you get these results from these data.
  Always say what version of Oracle you are using (for example, 11.2.0.2.0).

  Hello

  ORA-27072: IO file error

  Linux-x86_64 error: 28: no space is available on the device

  Looks like a system or OS, no SQL or PL/SQL problem problem.  I think you will answer sooner if you check this issue as 'Response' and start a new question in the forum of "General Question":

  https://forums.Oracle.com/community/Developer/English/oracle_database/general_questions/content

  My guess is that Oracle tries to allocate space in the tablespace temp, but cannot because the disk is full.  If you have a full disk, then create the space to this topic.

  I see nothing wrong with your code; Certainly, nothing which would cause an error like that.  The fact that the query has worked well for some time confirms that there is noting wrong with the request itself; It is just triggering a mistake elsewhere.

• How to run a query to update on the results to a spreadsheet

  Hey there,
  I'm new to this kinda thing.
  I received a spreadsheet that has 2 tablets, 1 is called SQL generates and has a ton of data. 1 is called SQL statement and a select statement in the first cell.
  I said to run an update query by using the worksheet and received this:
  = CONCATENATE("Update CARDMEMBERISSUE set CURRSTATUSCD = 'ACT', DATELASTMAINT = sysdate where AGREENBR =",A2,"and MEMBERNBR =",B2,"and ISSUENBR =",C2,";")
  
  = CONCATENATE("Insert into CARDMEMBERISSUEHIST (AGREENBR, MEMBERNBR, ISSUENBR, EFFDATETIME, CARDSTATCD, STATREASON, DATELASTMAINT, DATESENT) values (', A2, ',', B2, ',', C2", sysdate, 'Law', null, sysdate, null);' ")
  
  I don't know what to do or how to do this.
  It's that the lines in the worksheet as look, including the column header, A1 is empty.
  A B C etc.
  NBR MEMBERNBR QUESTION NBR CURRSTATUSCD PREFIX CARD NBR AGREETYPCD NBR EXT CARD ISSUE DATE PERS OWNER AGREE
  2 12 1 44 ISS g 22 22 19/10/2011

  = CONCATENATE bits are Excel formulas. Assuming that they properly drafted, they generate a set of individual sql statements. The first concaenatewill generates a set of instructions to update on the CardMemberIssue table, and the second will generate a set of insert statement in the CardMemberIssueHist table.

  You should be able to simply paste the instructions generated in any tool that you use to run sql to run. Before you do this right, make sure that you are running:

  alter session set cursor_sharing=force;
  

  before sticking anything in.

  This means there are a few sessions by running the same query (which is fine). Only, you will need to tell us why the query is run that many times :) Maybe, you need it!

• How to use a parameter query to select and display the data in the table of the façade

  Hiiiiii

  I am using Access 2007 database
  I want to select the specific data in the database using control of the chain as 'select product, size, weight of ProductInfo where barcode (chain control) =?'  and also display the same table of façade.

  I use the connected database toolkit.
  I saw the example of the parameterized insert, but it did not help to use parameterized select query, as well as to display data of parameterized select query.

  I looked for example on parameterized select query, but I don't have any.
  So pls guide me how to do this. I would like to know the other method (if any) that the use of parameter query to perform the same thing.
  If possble pls share a vi reference.
  Thank you!!!

  HII szewczak
  Thanks for the reply
  but I did not getsolution in one of your shared links
  My problem is solved. There is no need to use the parameter query to select control values
  In my case I want to display data from database where bar code is even entered by the user
  I use the data function DB TOOL CHOOSE and create the condition of chain based on concatenation of strings

  At present, the only way I can think of to avoid a call to UTL_HTTP. SET_BODY_CHARSET is to write your own little wrapper.
  In this way, you can specify the Boolean parameter or omit it if you choose to use named parameters:

  Hello Nri,

  What value does P18_SCHOOL_ID?
  If you look at the State of Session (toolbar) developer. If that does not have a value, it's your problem.

  You can create a calculation before the process that gives the correct value. (In one case more often, you have a report and when you click on the link change that id is activated and you see the recording in your form)
