• Delete records based on the foreign keys of oracle 11 g

  I have a requirement to remove the records from the tables in the order according to

  the existing foreign keys.

  I for example, the following tables and the pk, fk constraints:

  create table one

  (aa number (1),)

  descr varchar2 (20));

  ALTER table one

  Add constraint a_pk key (aa) primary;

  create table b

  (aa number (1),)

  descr varchar2 (20));

  ALTER table b

  Add constraint b_pk key (aa) primary;

  create table c

  (aa number (1),)

  descr varchar2 (20));

  ALTER table c

  Add constraint c_pk key (aa) primary;

  create table a2

  (aa number (2),)

  id_aa number (1).

  descr varchar2 (20));

  ALTER table a2

  Add constraint a2_pk key (aa) primary;

  ALTER table a2

  Add constraint a2_fk foreign key (id_aa)

  references a (aa);

  create table b2

  (aa number (2),)

  id_aa number (1).

  descr varchar2 (20));

  ALTER table b2

  Add constraint b2_pk key (aa) primary;

  ALTER table b2

  Add constraint b2_fk foreign key (id_aa)

  references b (aa);

  create table z

  (aa number (3),)

  id_aa number (1).

  id_bb number (1).

  descr varchar (20));

  ALTER table z

  Add constraint z_pk key (aa) primary;

  ALTER table z

  Add constraint z_fk1 foreign key (id_aa)

  references a (aa);

  ALTER table z

  Add constraint z_fk2 foreign key (id_bb)

  references b (aa);

  So, I want to choose the names of the tables in such an order so as

  deleting records will succeed...

  I built the following sql query (using the recursive subquery factoring):

  [p]

  with q (r_constraint_name, table_name, constraint_name, lvl) as

  (select table_name, constraint_name, r_constraint_name 1 lvl

  from user_constraints one

  where a.constraint_type = 'P '.

  Union of all the

  Select b.table_name b.constraint_name, b.r_constraint_name, q.lvl + 1 lvl

  from user_constraints b

  Join q

  on (q.constraint_name = b.r_constraint_name)

  where b.constraint_type = 'R '.

  )

  Select f.table_name, f.constraint_name, f.r_constraint_name, f.lvl

  q f

  [/ p]

  I want the results as the following list:

  Table-name

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

  B2

  A2

  Z

  A

  B

  C

  The table - B2, A2, Z - (in any order) must first referred in the list

  because they are based on the other three tables - A, B, C. Thus, in order to remove the

  A, B, C table records the B2, A2, table Z records must be beleted first.

  The query I posted above has the problem that it displays tables A2, B2 twice

  (1 because they have a pk and 2 because they have fk referring A, B relatively tables).

  Is there a solution for this problem?

  Note: I use db11g v2

  I wrote not all relationships of tables user_constraints (only argument constraint_name = r_constraint_name)

  Thank you

  Is there a solution for this problem?

  Yes - the 'solution' is to use ON DELETE CASCADE, as appropriate or write a procedure that removes tables in the proper order.

  The solution is NOT to try to use dynamic sql statements to do so.

  You already know the good parent/child relationships. Simply create a procedure that uses the correct order.

  Analyses are necessary in any case to determine the proper order AND press the appropriate values to use to remove the appropriate lines

  Your DDL for tables and constraints must be in a version control system

  Update the procedure when / if new constraints or tables are added to the application

  IMHO, you must use dynamic SQL NOT to try to adjust automatically if a new constraint appears. New constraints should not appear by accident - they appear ONLY as part of a well planned release.

• How can I delete records of a 3D table based on values in a field?

  In the attached table 3D I want to delete all the records that have no 3A 900000 / 3 has 900001/or 3A 900002 in field 2. Is there an easy way to do this?

  Thank you.

  Instead of delete why didn't you find and replace rather--much more effective anyway due to no resizing of the table.  Consider this in your subsequent treatment table.

  I am trying to remove the news that are published before 2012, but the tables in detail consists the notebook of the child based on the news_id has been. Request certainly simple deletion will not work
  
  Please advise and thank you in advance

  Once again, I tell you, do not need ON DELETE CASCADE in the Delete query.

  Just use the Delete query like: -.

  delete from news where TO_CHAR(news_date,'YYYY') <  2008;
  

  And the child tables are deleted as a result.

• How to identify records in a table for which no record exists in another table?

  Hello

  I have a table named CARE:

  Name of Type NULL

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

  FICHE_ID NOT NULL NUMBER

  AGENT_ID NUMBER

  FICHE_ID is the main KEY to the PLUG

  There is a table ACTIVITE_FAITE:

  Name NULL Type

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

  FICHE_ID NOT NULL NUMBER

  ACTIVITES_ID NOT NULL NUMBER

  NUMBER OF SECTEURS_ID

  NOT NULL NUMBER DURATION (8.2)

  ACTIVITE_FAITE_ID NOT NULL NUMBER

  NUMBER OF TYPE_ACTIVITE_ID

  FICHE_ID is a key for both tables dower (it references FICHE_ID. of the table INSERT)

  I just want to display the records of CARE for which there is no reference in the ACTIVITE_FAITE table. In other words, all the documents of record for records that have been created in ACTIVITE_FAITE.

  I tried without success:

  Select * from sheet f

  If f.fiche_id not in

  (by selecting af.fiche_id in Activite_faite af)

  Thank you very much for your help!

  Select * from sheet f

  where fiche_id not in (select fiche_id from activite_faite)

  is a way (this works because fiche_id is not nullable)

  where there is not (select null from activite_faite where f.fiche_id = a.fiche_id)

  is another way.

• Deleting records in an Oracle table

  I have a table of RESULTS and want to delete the records does not correspond to the account and IDS on the table 2.

  This is the request I have formed-

  delete results p

  where (p.account, p.match_value) not in

  (select the id from 2 account)

  However, NOT IN the clause seems to take too long to run, so I can change the query like this?

  delete results p

  Left outer join the 2 pd

  on p.account = pd.account

  and p.match_value = pd.id;

  Please suggest if it seems good.

  NOT IN often has performance issues. Also if there is no line in table 2 with null or id account it will not work as it should in any case. Try this. "

  delete from results where (account, match_value) in

  (select the account, the results match_value

  less

  Select id from 2 account);

• How one table based on another table on average?

  Example:

  1

  1

  2

  2

  3

  Array2 contains:

  1

  2

  3

  4

  5

  6

  In the end, ARRAY3 would contain:

  2                  (1+2+3)/3

  4.5               (4+5)/2

  6                  (6)/1

  This is my first go at it.  There are a lot of improvements that can be made (conditional index is one) but it seems to do what you want.  Table 1 and 2 must be the same size to make it work.

• Update of the table based on another

  Hello
  
  I'm trying to update a date column in a table based on another table. There is a unique ID in each table that identifies and connects each person:

  This is the error:

  How can I update this table with only the most recent date?

• change the order of a table with another table

  I want to change the order of a 1 d table based on another table 1 d that specifies the order.  For example, I have a table including the following items: 12, 13, 14, 15, 16.  And I have another 1 d array that specifies the order of 3, 4, 0, 1, 2.  I want the table resulting in 15, 16, 12, 13, 14.  How can I do this?  It must be really easy.  Another example, I give myself a table in the order following 1,2,3,4,5,6,7 and I an order specifying the array containing the 0,6,1,5,2,3,4.  Therefore, the resulting table must be 1,7,2,6,3,4,5.  ???

  It is, in fact, quite easy.  Put an "Array Index" inside a loop and thread the two tables in it.  Disabled automatic indexing on the input array.  Wire of the array element located on the border of the for loop, and you'll have the desired table.
