• How to find the child level for each table in a relational model?

  Earthlings,
  
  I need your help, and I know that, "Yes, we can change." Change this thread to a question answered.
  
  So: How to find the child level for each table in a relational model?
  
  I have a database of relacional (9.2), all right?
  

  .
       O /* This is a child who makes N references to each of the follow N parent tables (here: three), and so on. */
      /↑\ Fks
     O"O O" <-- level 2 for first table (circle)
    /↑\ Fks
  "o"o"o" <-- level 1 for middle table (circle)
     ↑ Fk
    "º"

  Tips:
  -Each circle represents a table;
  -Red no tables have foreign key
  -the picture on the front line of tree, for example, a level 3, but when 3 becomes N? How is N? That is the question.
  
  I started to think about the following:
  
  First of all, I need to know how to take the kids:

  select distinct child.table_name child
    from all_cons_columns father
    join all_cons_columns child
   using (owner, position)
    join (select child.owner,
                 child.constraint_name fk,
                 child.table_name child,
                 child.r_constraint_name pk,
                 father.table_name father
            from all_constraints father, all_constraints child
           where child.r_owner = father.owner
             and child.r_constraint_name = father.constraint_name
             and father.constraint_type in ('P', 'U')
             and child.constraint_type = 'R'
             and child.owner = 'OWNER') aux
   using (owner)
   where child.constraint_name = aux.fk
     and child.table_name = aux.child
     and father.constraint_name = aux.pk
     and father.table_name = aux.father;

  Thought...
  We will share!

  If you have a cycle, you have some problems.

  (1) it is a NOCYCLE keyword does not cause the error, but that probably requires an Oracle version which is not so far off support. I don't think it was available at the time 9.2 but I don't have anything old enough to test on

  (2) If you try to write on a table and all of its constraints in a file and do it in a valid order, the entire solution is probably wrong. It is impossible, for example, to generate the DDL for MY_EMP and MY_DEPT such as all instructions for a table come first, and all the instructions for the other are generated second. So even if NOCYCLE to avoid the error, you would end up with an invalid DDL script. If that's the problem, I would rethink the approach.

  -Generate the DDL for all tables without constraint
  -Can generate the DDL for all primary key constraints
  -Can generate the DDL for all unique key constraints
  -Can generate the DDL for all foreign key constraints

  This is not solidarity all the DOF for a given in the file object. But the SQL will be radically simpler writing - there will be no need to even look at the dependency graph.

• How to find the rank lowest for each student using a Select query?

  Hey I'm having a little trouble here
  
  I have this table
  
  
  Student - Grade
  
  John - 8
  Richard - 9
  Louis - 9
  Francis - 5
  John - 13
  Richard - 10
  Peter - 12
  
  Shades may vary from 0 to 20.
  
  Name - varchar (50)
  Grade - wide
  
  I'm trying to generate a SQL search to search for each rank lowest for each student.
  
  So far, I did:
  
  Select s.name, s.grade
  s student
  where s.grade = (select min (grade) of student)
  
  The result of this search returns me only the rank lowest of all ranks posted above, which is Francis - 5.
  
  I want to find the lowest rank, but not only for Francis, but for all students in the table.
  
  How do I do that?
  
  Thank you in advance.

  Ok

  Now we head into analytical SQL:

  with student as (select 'John' name, 8 grade, 'fail' result from dual union all
                   select 'John' name, 13 grade, 'pass' result from dual union all

                   select 'Peter', 12, 'pass' from dual)
  -- End of your test data
  SELECT   name,
           MAX (result) KEEP (DENSE_RANK FIRST ORDER BY grade) result,
           MIN (grade) min_grade
  FROM     student

  Thank you.

  First run a statspack or AWR report and take a look in v$ librarycache

  Numbers are irrelevant. The reports are a little more relevant, but not necessarily a problem.

  How to find the value max and min for each column in a table 2d?

  For example, in the table max/min for the first three columns would be 45/23, 14/10, 80/67.

  Thank you

  Chuck,

  With color on your bars, you should have enough experience to understand this.

  You're a loop in the table already.  Now you just need a function like table Max and min. loop.  And you may need to transpose the table 2D.

  Do you have a procedure?

  Should you output only for the months you passed in the parameter?

  The easiest way is to set the parameter as date. When you go such as p_date as DATE ' 2014-10-01', then you can

  PROCEDURE two_dates)

  p_date IN DATE

  p_first_sunday DATE

  p_second_saturday DATE

  )

  IS

  BEGIN

  p_first_sunday: = NEXT_DAY (TRUNC (p_date, 'MM') - 1, TO_CHAR (DATE ' 2014-10-12', 'DAY'));

• How to find the velocity of an incremental encoder

  I use the RE22I encoder which can give up to 8192 pulses per revolution, I have A, B, Z reports that I use an fpga as a controller Please help me.

  How to find the speed of the encoder using these signals I'm going to have a clock in the fpga sysytem will help.

  Start by looking at the information on Wikipedia on the rotary encoders and a book on encoders OR white.  These articles will give you a basic understanding of the encoder and the signals it produces.

  With proper decoding, you can get the direction and momentum of each of the points on your encoder 8192.  If the tree can reverse (same vibration on one point unique all-in-mnearly stationary), full decoding must be used.  If data are only of interest while the tree turns in a direction and speed will not close to zero, a simple decoding can be used.  Decoding of a quadrature encoder is a good way to learn to use a state machine.  Signals A and B can exist in only four possible combinations, but the possible transitions to do interesting things.

  Define DECODING is a purely logical exercise and it is a simple coding in LabVIEW, such as a state machine.  There are examples, Desing Patterns, or project templates (depending on your version of LV) that come with LV to help you get started.

  By using the channels A and B you can update your calculation of velocity 8192 times per turn.  With the help of Z you get only an update by the revolution. You use depends on your application.  The pulse of Z is also useful to define a reference position for the measurement of phase angle.
