  Hi, Nihar,

  You almost had it! You just need to correlate the subquery for the main UPDATE statement, like this:

  UPDATE     user_table     u     -- USER is a built-in function; it's not a good table name
  SET     password = ( SELECT  encrypt
                 FROM    reset     -- RESET isn't a very good table name, either
                 WHERE   serial     = MOD ( LENGTH (u.username)
                                           , 10
                                 )
               );
  

• How to join tables and get ppl not in the list of the other table

  Hi, I have 2 tables

  Table (girlscoutid, quarter, point)

  Table b (girlscoutid, fname lname)

  I want to get the names of ppl who didn't sell any point/s for Q4

  girlscoutid	agenda	quarter
  7771	drinks	4QS
  9000	Tickets	4QW
  7771	Cookies	2QS
  5085	books	3QF
  3010	Tickets	3QW
  5085	Cookies	1QF

  lscoutid	fname	lname
  7771	Jenn	Richochet
  9000	Laura	Wilkins
  5085	Sally	Mae
  3010	Dora	McKenzie

  That's what I have, however, I get duplicates and also 7771 appears on the list even if she sold something on the 4th quarter. Any suggestions?

  SELECT fname, lname, a.girlscoutid

  Of a, b

  WHERE a.girlscoutid = b.girlscoutid

  AND the term NOT AS "4Q_";

  Hello

  So, all the information that you want to see figure in table b, but if you want to see it depends on the table has.

  This looks like a job for a semi Join.  Here's a way to do it:

  SELECT b.fname

  b.lname

  b.girlscoutid

  B

  LEFT OUTER JOIN has IT a.girlscoutid = b.girlscoutid

  AND a.quarter NOT AS "4Q_" - or a.TERM, if it is the column

  WHERE a.girscoutid IS NULL

  ;

  What you posted was an INNER join, where the rows of each table are included in the only game that if they have a corresponding row in the other table.

  An OUTER join includes all the rows in a table (table b in this case) if they have a match in the other table.  If a line of b has no corresponding row in a, then all the columns that are supposed to come from table will be NULL in the result set.  Given that the join condition includes = b.girlscoutid a.girlscoutid, this means that the only way to a.girlscoutid can be NULL in the result set is if the b line is included although it has no corresponding line one, which are exactly the lines that we want to display.  (You can try to run the query above with the WHERE clause, deleted, just to see how it works.)

  Alternatively, you can get the desired results by using a subquery NOT EXISTS, a NOT IN subquery or analytical functions.  The semi join, supra, is probably the most effective solution.

  Thank you!!

  Two standard methods to compare the tables are either to use DEFINED such as UNION, UNION operations or LESS.
  Or use a FULL OUTER JOIN.

  If the structure of the table is the same and that you want to compare all the columns, then set them operators are the best way.

  If you want to compare only on one or more columns and want to see the other columns, then a FULL OUTER JOIN is the best way.

  Here is an example

  select A1, A2,
        count(distinct sourcetable) cnt_tables,
        count(sourcetable) cnt_records,
        count(case when sourcetable = 'A'  then 1 end) record_is_in_A,
        count(case when sourcetable = 'B1'  then 1 end) record_is_in_B1,
        count(case when sourcetable = 'B2'  then 1 end) record_is_in_B2
     (select 'A' sourceTable, a.* from tableA a
      union all
      select 'B1' sourceTable, b1.* from tableB1 b1
      union all
      select 'B2' sourceTable, b2.* from tableB2 b2
     )
  group by A1, A2
  having  count(distinct sourcetable) < count(sourcetable) ;
  

  It is an example. It will show you the records that have duplicate data in the following tables.
  If you want to display all records that are in A but not in B1, you can add a few other checks.

• Mobile based on the size and the position of the other table

  I have the impression that there is an easy solution for this... or it there is no solution at all... but here goes:

  I want to use table 2 to indicate 'total time' as the sum of all time in table 1. Table 1 is set to automatically filter some lines (basically, it creates a dynamic playlist based on certain criteria). What I wish is to table 2 'float' a certain number of Table 1 below, so that as table 1 grows or shrinks according to the filtered content, table 2 remains the same distance from the bottom of table 1. Is - this unreasonable? It seems I've seen tables 'hustles' other tables according to size changes (not the desired effect in these cases, but what I DO want to here).

  Hi mikey,.

  This seems to be the default behavior in Numbers ' 09, but the function may not have been included in 3 numbers. I'm sure someone will test and report on it before long.

  Demo below is in Numbers ' 09.

  

  Coffee table is a double to the top. After positioning the lower level of the original table, I inserted two rows in the original and watched 'push' that the lowest low, keeping the space between them.

  I reformatted the cells in column B, CheckBox and verified that a few of them.

  Then I opened the Reorganize pane. and the filter rule (see the lines "... ") displayed the value:

  By clicking on "see the lines...". "box produces this result:

  

  Note: I had selected all the header cells in column B before starting the filter. The first image was captured after unchecking the checkbox 'display lines... '. "developing the table and leaving only the cells in the (previously) selected filtered lines.

  As mentioned, the example is in Numbers ' 09 / numbers 3 behavior may be different.

  Hello

  Remember the ABC's of the GROUP BY:

  When you use a GROUP BY clause or in an aggregate function, then all in the SELECT clause must be:

  (A) a ggregate function,

  (B) one of the expressions "group By."

  (C) adding to C, or

  (D) something that Depends on the foregoing.  (For example, if you "GROUP BY TRUNC (dt)", you can SELECT "TO_CHAR (TRUNC (dt), 'Mon - DD')").

  To ask him, there are 5 columns in the SELECT clause.  The last one is a function MAX (...); It is an aggregate, is not serious.

  The first 2 columns are also named in the GROUP BY clause, so that they are well.

  The other 2 columns, country and internal_Id do not match any of the above categories.  These 2 columns cause the error.

  There are many ways to avoid this error, each producing different results.  You could

  • remove these 2 columns in the SELECT clause
  • Add these 2 columns in the GROUP BY clause
  • use the aggregation such as MIN, 2-column functions
  • remove the country from the SELECT clause and add internal_id to the GROUP BY clause
  • remove the internal_id from the SELECT clause, and add countries to the GROUP BY clause
  • ...

  What are the results you want?

  Whenever you have a question, please post a small example of data (CREATE TABLE and INSERT statements) for all the tables involved, so people who want to help you can recreate the problem and test their ideas.  Also post the results you want from this data, as well as an explanation of 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
  
  I'm trying for a few hours to get information from inside a trigger to another table in the same pattern.
  
  My trigger is PSE_BKB. NUM_PHANTOM_BP
  
  I first tried a simple solution...
  
  
  CREATE OR REPLACE TRIGGER PSE_BKB. NUM_TR_PHANTOM_BP
  BEFORE DELETING, INSERTION OR UPDATE
  ON PSE_BKB. NUM_PHANTOM_BP
  REFERRING AGAIN AS NINE OLD AND OLD

  of pse_bkb.num_objekt_verb ov
  where ov.phantom_key =: old.phantom_key
  )
  and o.typ = "NUM";
  
  ...
  
  Explanation: my trigger table is PSE_BKB. NUM_PHANTOM_BP.
  
  On the pse_bkb.num_objekt_verb of the table, I have a relationship 1: n to one or several object-key (field named obj_key!) on my referenced key: old.phantom_key. With this obj_key, I want to watch the weather, I have one or more lines in the table type num_objekt "NUM". So the internal selection gives me all the num_objekt_verb obj_key with my: old.phantom_key and with whom I count the number of lines I have on num_objekt with type "NUM".
  
  The problem is that the trigger does not see the table.
  
  I tried many variations.
  
  The latest version I tried was with a cursor inside the trigger definition as in the block of code below.
  
  For debugging purposes, I inserted a RAISE_APPLICATION_ERROR in the inner loop - see below. The v_obj_key variable is never defined, as in all the other variations, I tried-, I still see the predefined "gugus" in the declare section.
  
  It seems that oracle can not read other tables at this point. La: old.phantom_key is defined (in this simple example there would come a return obj_key).
  
  Thanks in advance for your help - and excuse my English.

  The reason why you get count_n = 0 in tr_c is that there is no line in B with key_c = 17, to the moment you arrive at tr_c. The removal of B has already occurred, and since you're in a single transaction, the application for tr_c:

  select count(*)
    into   counter_n
    from   a aa
    where  aa.key_a in (select distinct(bb.key_a)
                        from   b bb
                        where  bb.key_c = v_ph_key
                       )
    and    aa.typ = 'n';
  

  'knows' that the row has been deleted then gets a number of 0.

  I added a set of instructions dbms_output to show the order in which triggers run, and that's what I get:

  SQL> delete from b_vw where key_a = 1 and key_c = 17 ;
  in trigger b_tr_vw
  In tr_b
  in tr_c
  delete from b_vw where key_a = 1 and key_c = 17
              *
  ERROR at line 1:
  ORA-20077: Remark: counter_n: 0 counter_s: 0 v_ph_key: 17 old.key_c: 17
  new.key_c:
  ORA-06512: at "OPS$ORACLE.TR_C", line 38
  ORA-04088: error during execution of trigger 'OPS$ORACLE.TR_C'
  ORA-06512: at "OPS$ORACLE.B_TR_VW", line 17
  ORA-04088: error during execution of trigger 'OPS$ORACLE.B_TR_VW'
  

  Thus b_tr_vw trigger is triggered first and deletes a B. trigger fires tr_b as part of this statement to remove and check against A, happening apparently so no error is triggered and succeeds the removal of B. Now tr_b_vw takes back control and deletes C. Since the B line which has key_c = 17 already deleted a control for counter_n > 0 and counter_s = 0 fails and raise you the-20002 error. Note that I'm assuming that the error of-20077 you lift is just to see the values and is not intended to be part of your actual code.

  Because I have really no idea what you're trying to accomplish here I can't offer a lot of advice that you might want to try entering two tr_c of the tr_b_vw trigger validation queries before deliver you the removal of b and put the counter_n > 0 and counter_s = 0 control under tr_b_vw to decide whether or not you want to remove.

• Release of updated with the value of the other Table

  Hello
  I need the sum there point TableB and insert/update this value in the X field in TableA. I can do this with select statements regular when I add values in my statement, but I'm getting errors now. Need help on how to code the trigger to do this, thank you.
  ORA-00936: lack of expression
  

  SELECT a.X, SUM(b.Y), 
  INTO a.X
  FROM TableA a, TableB b
  WHERE a.PK = b.FK;

  Ok. I think I understand now what's going on. Think logically that you create the customer first and only then customer can create orders, right? So when you insert a customer into the table DEMO_CUSTOMERS there is no customer order in the DEMO_ORDERS table. As a result, the CREDIT_LIMIT column remains NULL.

• Domain! = Insert then in the other Table

  Hello
  I can't figure out how to create a trigger that inserts data based on cases an old.field! = new.field. If the field has been changed to
  a tbl_test table then insert this file into the other tbl_test_history of the table. It's a little different since I want to insert a record if an update
  has taken place. The update will still take place at tbl_test, but I want an insert will be held at tbl_test_history.

  CREATE OR REPLACE TRIGGER AU_INSERT_TEST_HISTORY 
    AFTER UPDATE
    ON TBL_TEST   FOR EACH ROW
  WHEN (
      OLD.Orange != NEW.Orange
   OR OLD.Apple != NEW.Apple
        )
  BEGIN
  INSERT INTO TBL_TEST_HISTORY
   (ORANGE,
    APPLE
    BANANA,
    GRAPE
  )
    select ORANGE,
           APPLE
           BANANA,
           GRAPE
  FROM TBL_TEST, TBL_TEST_HISTORY
    WHERE  TBL_TEST.PK_TEST_ID = TBL_TEST_HISTORY.PK_TEST_ID;
  END AU_INSERT_TEST_HISTORY;
  /

  I have a separate trigger that will insert records from tbl_test to tbl_test_history. This trigger compiles without error but when I
  create a record in tbl_test I have an error message. I don't know if the syntax is correct, can someone help me with this?

  My bad. I put the colon: in the when clause. They were not there in your code. I usually use an if condition, which is a little different.

  I added a NEW logic to also consider the comparison of NULL values.

  CREATE OR REPLACE TRIGGER AU_INSERT_TEST_HISTORY
    AFTER UPDATE  ON TBL_TEST
    FOR EACH ROW
  BEGIN
    if nvl(:old.ORANGE,'xxx') != nvl(:new.ORANGE,'yyy')
       OR nvl(:old.APPLE,'xxx') != nvl(:new.APPLE,'yyy')
    then
      INSERT INTO TBL_TEST_HISTORY
       (ORANGE, APPLE, BANANA, GRAPE)
      values (:new.ORANGE,
               :new.APPLE,
               :new.BANANA,
               :new.GRAPE);
    end if;
  END AU_INSERT_TEST_HISTORY;
  / 
  

  In addition, you can consider making trigger a trigger AFTER INSERT or UPDATE.

  Then you would also put the values inserted early in your history table.

  Welcome! on the forum.

  You can include the code and data in the {code} tags

  If I'm good, and I know what is your condition

  insert into emp2 ( data1, data2)
  select data1, data2
  from emp1

  Then do something like this:

                        || :NEW.schosen
                        || ') is not valid.'
                      );
  end;
  /
  

  DBMS_OUTPUT creates only a message. The message may not be displayed, and if this is the case, then the user cannot see it. The DML will still take place.
  I used instead, RAISE_APPLICATION_ERROR to keep the DML does not happen. It displays a message like

  ORA-20000: Please re-enter class id and student id as class (1) or student (3) is not valid.
  

  ' 2 ' game ' means ' an official competition in which two several people or teams competing.

  What individuals or teams are competing in this case?
  In any case, the question wasn't 'that 'game' means', but

  What do you mean when you say "going to match?

  I think that now you're saying that the new values of (class.cid, class.schosen) must be equal to (or "fit") some existing (stu.cid, stu.sid).

  3. thanks for your tip, I learned how to use '{code} '.

  4. it's really goes with the exception of MUTATING_TABLE. So, how do to fix the trigger to show me INVALID_STU EXCEPTION when I try to choose a student does not belong
  a class?

  Don't refer to the table of class in the trigger, and the error table mutation occur. All the information you need are in the stu table, so there is no need to query the table of class, anyway.

• How to extract the values of the other tables in the process upon request

  Hi all
  In Oracle Apex 4.1.
  The Leave_transaction Table contains the following fields,

  1.Leave_id
  2.Emp_name
  3.From_date
  4.To_date
  5.Remaining_days

  The Emp_Master Table contains the following columns

  1.Emp_id
  2.Emp_Name
  3.Remaining_days

  Holiday_master table contains a list of the dates of the holidays as 'From_Date '.
  
  I have the form based on the Leave_Transaction Table,
  I created the process,
  "Sur-Soumettre after calculations and validations of."
  and posted the following PLSQL code,

  declare
  days number(3);
  ex_days emp_master.remaining_days%type;
  new_rem_days emp_master.remaining_days%type;
  begin
  select count(*) into days from (select dt
  from(
      select to_date(:p1_from_date, 'DD-Mon-YYYY') + rownum -1 dt 
          from dual
  connect by level <= to_date(:p1_to_date, 'DD-Mon-YYYY') - to_date(:p1_from_date, 'DD-Mon-YYYY') + 1)
  where to_char(dt,'fmday') not in ('sunday','saturday') minus (select holiday_start from holiday_master)) dual ;
  
   select remaining_days into ex_days from emp_master where upper(emp_name) = upper(:APP_USER);
  new_rem_days := ex_days - days;
  
    update emp_master set
      remaining_days = new_rem_days
      where upper(emp_name) = upper(:APP_USER);
  update leave_transaction set
      remaining_days = new_rem_days
      where upper(emp_name) = upper(:APP_USER) and
       leave_id=(select max(leave_id) from leave_transaction);
  
  end;

  If the date is between from_date and To_date comes Saturday and Sunday or if any Date exists in the table of Hpliday_master he will exclude and return the count (*) rest of dates.
  For example,.
  
  If the From_date is 04-may-2012'
  and To_date is 08-may-2012,
  
  Here the dates 5 May and 6 may are "Saturday" and "Sunday".
  
  and if any date between From_date and To_date is exist in the Table Holiday_Master
  That is to say that here it is 07-may-2012,
  
  Then the remaining dates are (excluding sat, Sunday and dates in holiday_table).
  
  04-may-2012,
  08-may-2012.
  
  the count (*) is 2.
  
  I use the code above but it return 5.
  I think that this
  

   
  ...where to_char(dt,'fmday') not in ('sunday','saturday') minus (select holiday_start from holiday_master))

  code does not work.
  Can someone help me solve my problem.

  You can use in the detail of the line?

  In this case, put the af:table component in the af: column and assess the condition of rendering on the value of the column.

• Interview with numerous Subselects on the same table

  Hello
  
  Please consider the example below (Oracle 11 g):
  

  create TABLE test1 (order_id number, CODE VARCHAR2(10), VALUE NUMBER);
  
  insert into test1 VALUES (1, 'A', 100);
  insert into test1 VALUES (1, 'B', 200);
  insert into test1 VALUES (1, 'C', 300);
  insert into test1 VALUES (1, 'D', 400);
  insert into test1 VALUES (2, 'A', 10);
  insert into test1 VALUES (2, 'B', 20);
  
  SELECT order_id,
         CODE,
         VALUE,
         (SELECT VALUE FROM test1 t1
         WHERE t1.order_id = t.order_id
         AND   t1.code = 'B') b_Value,
         (SELECT SUM(VALUE)/COUNT(*) FROM test1 t1
         WHERE t1.order_id = t.order_id
         AND   t1.code IN ('C', 'D')) cd_Value,
         (SELECT COUNT(*) FROM test1 t1
         WHERE t1.order_id = t.order_id
         AND   t1.code IN ('C', 'D')) cd_qty
  FROM   TEST1 t
  WHERE  CODE = 'A';

  In my case the real life, I do not have 3 but dozens of columns in the subquery like those. The performance is OK, but I was wondering if there was a better way with respect to performance and maintainability to write this query.
  
  I thought in the WITH clause, but did not see how it could help a lot.
  
  Please note that some subqueries may be more complex than just by lifting a column, as in the cd_value/cd_qty column.
  
  Any suggestions?
  
  Thank you
  Luis

  Simpler, but will go for two table scans. You can use outer joins according to your requirement.

  select t1.order_id,
         t1.CODE,
         t1.VALUE,
         max(decode(t2.code,'B',t2.value)) b_value,
         sum(decode(t2.code,'C',t2.value,'D',t2.value,0))/nullif(sum(decode(t2.code,'C',1,'D',1,0)),0)  cd_value,
         sum(decode(t2.code,'C',1,'D',1,0))  cd_qty
  from TEST1 t1,test1 t2
  where t1.CODE = 'A'
  and t1.ORDER_ID = t2.order_id
  group by t1.order_id,
         t1.CODE,
         t1.VALUE
