• PLSQL block for childtable foreignkey account data columns

  Hello
  
  I want to generate report for child table foreign key column data number of records based on the entry in the parent table.
  
  
  for example:
  
  
  '' SELECT b.table_name as table_name, d.column_name, b.R_CONSTRAINT_NAME. ''
  From user_constraints a, user_constraints b, user_ind_columns c, user_cons_columns d
  WHERE a.constraint_type = 'P' AND
  a.CONSTRAINT_NAME = b.R_CONSTRAINT_NAME AND
  b.CONSTRAINT_TYPE = 'R' AND
  a.table_name = c.table_name AND
  a.constraint_name = c.index_name AND
  AND d.constraint_name = b.CONSTRAINT_NAME
  a.table_name = 'TABLENAME' "
  
  
  
  This above query give all the child tables and a list of the foreign key column (column childkey).
  
  based on the results of the above query I want to generate each number of records table foreign key column.
  
  
  example:
  
  I have the table DEPT / EMP in the query above, I'll give you table DEPT, it will give the output "EMP".
  
  My data in the table emp like that
  
  My emp table has the datalike
  EMPNO, ename, deptno
  100 10 aaa
  101 20 BBB
  102 30 cccc
  103 10 ddd
  Eee 104 20
  105 30 FFFF
  
  
  I want to report as
  number of records deptno table
  2 10 EMP
  2 20 EMP
  30 2 EMP
  
  Please any body has the solution please post your solutions here.
  If you have any logic please post here, I'll try with this logic.
  
  
  Thank you.
  :)

  Test data:

  drop table T2;
  drop table T3;
  drop table T1;
  
  create table T1(a, B, C, primary key(a,B)) as select 1,2,3 from DUAL;
  
  create table T2(a,B,D) as select 1,2,4 from DUAL connect by level <= 2;
  alter table T2 add constraint FK2 foreign key(a,B) references T1;
  
  create table T3(a,B,E) as select 1,2,5 from DUAL connect by level <=3;
  alter table t3 add constraint fk3 foreign key(a,b) references t1;
  

  First SQL to create the SELECT statements, you need:

  VARIABLE OWNER varchar2(30);
  VARIABLE TABLE_NAME varchar2(30);
  exec :table_name := 'T1';
  
  select
  'select ''' || R_OWNER || '.' || R_TABLE_NAME || ''' parent, '''
  || OWNER || '.' || TABLE_NAME || ''' child, '''
  || COLS || ''' fk_cols, '
  || COLS || ', count(*) cnt from ' || OWNER || '.' || TABLE_NAME
  || ' group by ' || cols as sql_text
  from (
    select NVL(:OWNER,user) r_owner,:TABLE_NAME r_table_name,
    OWNER, TABLE_NAME,
    LISTAGG(COLUMN_NAME, ',') within group(order by POSITION) COLS
    from ALL_CONS_COLUMNS
    where (owner, constraint_name, table_name) in (
      select owner, constraint_name, table_name from ALL_CONSTRAINTS
      where CONSTRAINT_TYPE = 'R'
      and (r_owner, r_constraint_name) = (
        select OWNER, CONSTRAINT_NAME from ALL_CONSTRAINTS
        where CONSTRAINT_TYPE = 'P'
        and (OWNER, TABLE_NAME) = ((NVL(:OWNER,user),:TABLE_NAME))
      )
    )
    group by OWNER, TABLE_NAME
  );
  
  SQL_TEXT
  -------------
  select 'STEW.T1' parent, 'STEW.T2' child, 'A,B' fk_cols, A,B, count(*) cnt from STEW.T2 group by A,B
  select 'STEW.T1' parent, 'STEW.T3' child, 'A,B' fk_cols, A,B, count(*) cnt from STEW.T3 group by A,B
  

  Test one of the SELECT statements:

  select 'STEW.T1' parent, 'STEW.T2' child, 'A,B' fk_cols, A,B, count(*) cnt from STEW.T2 group by A,B;
  
  PARENT  CHILD   FK_COLS A B CNT
  ------- ------- ------- - - ---
  STEW.T1 STEW.T2 A,B     1 2   2
  

  The SELECT statements must be tested separately because the number and type of foreign keys may vary.

• IKM Oracle Multi Table Insert obsolete?

  Can someone tell me the right way to do it in 12 c?  Everything I tried publishes two inserts instead of an insert of all.

  Thank you

  I have a problem in the execution of the trigger. I have a small plsql block in the trigger, and I want to run it as a dynamic medium. but it gives the error. Please find the code of the trigger. Here my intension is that the column name used in trigger must be dynamic. In the future, if I want to pass the name of the column, I do without modification in the trigger.
  The error im getting is "ORA-01008: not all variables.

• The default values on the retail block for dummy record gets inserted in detail blk

  Hi all
  
  I have a master block
  a block of detail and a detail for detail block block
  
  For every master I have or have no certain records in the block of retail
  
  for each master, I have a few detail records
  
  for each detail record I may or may not have the corresponding detail records
  
  Let's take an example
  I navigate a primary record to the detail record.
  in the 3rd block of retail, there is no record for the record in detail, but I have some default values.
  
  Now I navigate to the 3rd block of detail and I do not insert records and then exit the screen
  
  Here oracle asks me to save all the changes I made (I did no changes)
  and by clicking on Yes, there is a dummy record is created for a 3rd detail record
  
  Please help me
  
  Thank you

  This is the default values are to mark the block as being changed. That's why you get the message "do you want to save the changes.

  I suggest that you fill out elements of the base with the default values table and fill out the matching elements from the base on a prior insertion trigger table.

• Possible to insert more than once in the same table using multi table insert?

  I used multi-table insert before insert a source separate from the tables without problem.
  
  However, when I want to insert into the same table two or more distinct lines, I encountered a problem because when I call nextval on the sequence since this is the same sequence # will try to use the same number for two inserts, which will raise a violation of PK constraint on the 2nd insert.
  
  A way around this problem?

  Another option is to create the sequence with increases of 2 or however many tables, you are targeting.
  When you then specify the. NEXTVAL, you must subtract the relative number of it, apart from the first table that you insert in to.

  Something like that;

  drop table t1;
  
  create table t1 (a number, b number);
  
  drop table t2;
  
  create table t2 (a number, b number);
  
  drop sequence test_seq
  /
  
  create sequence test_seq increment by 2 minvalue 0
  /
  
  insert all
  when 1 = 1 then
    into t1 (a, b) values (test_seq.nextval, 1)
  when 1 = 1 then
    into t2 (a, b) values (test_seq.nextval  - 1, 1)
  select 1, 1 from dual
