• How to find the tables placed only on pages.

  Hi experts,

  I find all the tables in the document (no XML Indd file.) .indd There is only a certain number of tables. And a table in the master page also. Now I'm trying to get back only the tables except the master page. How can I got it?

  I used the following code. But it is not working properly.

  var myTables is app.activeDocument.stories.everyItem () .tables;.

  App.Select(mytables[0]);

  var myTableCount = myTables.length;

  Alert (myTableCount);

  for (var i = 0; i < myTableCount; i ++) {}

  var myTableObj = myTables [i];

  Alert (myTableObj.parent);

  Try

  {

  var myTableObj.parent.parentPage.name = XXX;

  If (xxx.match("^[0-9]+$"))

  {

  Alert ('table');

  myTableObj.label = 'table' +(i+1);

  }

  on the other

  {

  Alert ("Master Page table");

  }

  }

  catch (e)

  {

  Alert (e.message);

  }

  }

  Always throw catch loop...

  Can someone guide me...!

  Thank you and best regards,

  Hi Peter,.

  Finally, I close with the codes below. It make me fight a lot...

  var pagelen = app.activeDocument.pages.length;

  Alert (pagelen);

  for (var i = 0; i)<>

  {

  var pageitemlen = app.activeDocument.pages [i].pageItems.length;

  for (var j = 0; j)<>

  {

  v var = app.activeDocument.pages [i] .pageItems [j] .tables;

  Alert (v.Length);

  for (var x = 0; x)<>

  {

  App.Select (v [x]);                                                      Here, I can select.

  App.Selection [0] .label = "table" + count;

  Count ++;

  myTables.push (v [i]);

  }

  }

  }

  Peter, thank you very much for your time in Golden for my problem...

• How to find the table?

  Hello
  
  I have a java Apps to connect to a database of GR 11, 2.
  When I clicked on a "billing" module, I don't 'a number' 1,641.00 error in java logs that cause billing does not be generated.
  I don't even enter this value. I don't know if this error at the level of the table or during analysis on the coast of java it fetch a numeric variable placeholder.
  I simply assume that it is at the database level. And assuming that I am the only user in the database.
  How can I get this operation with the 1,641.00 value and determine which table was is inserted to the error? In V$ SQLAREA maybe?

  I have to disagree. If the application is to throw an exception and the journal contains her not the information necessary for you tell what is causing the exception, and then the application has ALSO a problem.

  java.lang.NumberFormatException: Not a number: 1,641.00
       at com.ibm.icu.math.BigDecimal.bad(BigDecimal.java:3894)
  

  Add additional record to the app to catch the exception and discover the connection, the request and the record that causes the error.

  Troubleshoot, to gather information when the problem actually occurs and work your way backwards.

  If you say that the problem did not exist before the developer made the change then prove it by running the old code against the same data. If it works then the problem is with the change that made the developer.

  I don't know if I understand your problem, but have you had a glance at the data dictionary views USER_DEPENDENCIES or ALL_DEPENDENCIES?

  It has classified hard dependencies of objects.
  If a table is used directly (not in dynamic SQL code in a string) in an object PL/SQL, the dependency is available in the stated points of view.

• How to find the table - is - this normal table or external table?

  Hello
  
  
  Regardless of DML operations in normal and reading tables only access tables outside, is there a way to find the specified table is regular table or the external table?
  
  Thanks in advance.
  
  Suresh.

  One possibility would be to query the ALL_EXTERNAL_TABLES data dictionary view. If there is a line in ALL_EXTERNAL_TABLES to the table, wondering (I assume you know that you query a table, a view, or a synonym), it is an external table. Otherwise, it's an ordinary table.

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

  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.

• 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.

  What happens if the PL/SQL table has NULL values. Question is how you want to handle NULL values. You want to ignore nulls as GROUP BY do? If you want to consider NULL values, you can say if you want to order the NULLS FIRST or NULLS LAST. I guess that logical GROUP BY:
