• How to find the lines, where the second column only has a defined value

  I have a table like
  

  CREATE TABLE MY_MAP
  (
    USERID     NUMBER(10)                    NOT NULL,
    SYSTEMID  NUMBER(10)                    NOT NULL,
  )

  The data in the table can be as below
  

  INSERT INTO MY_MAP VALUES(1,6);
  INSERT INTO MY_MAP VALUES(2,6);
  INSERT INTO MY_MAP VALUES(3,6);
  INSERT INTO MY_MAP VALUES(1,9);
  INSERT INTO MY_MAP VALUES(2,7);

  Now my requirement is to find all these IDS that are at systemid 6 but not at 9. That is to say
  
  2.3. [since 1 is both in the 6 and 9], should not be recovered.
  
  I did two courses is a loop. Can someone give me a single query to do?

  SQL> select * from MY_MAP m

• How to find the connection line

  Hello

  I have a spatial table with geom type in 2002.

  I have a set of line (for example say it's 5 rows) attach image.

  I need to find the line that is internal linking to these 5 rows. I mean, it's a dividing line has the inside line.

  I am unable to get the inner lines of a border.

  If I have a spatial query table I get limit but I want inner lines.

  Fix is instant for ref.

  Thanks in advance

  This is because CONCAT_LINES does not create a polygon, it only concatenates lines in a new line. But always a line (even if the endpoint and the starting point of this line may be the same).

  It might be a good idea to start reading the Documentation space: content, since it seems that there are some concepts in Oracle Spatial, which are not clear to you. Basically: there is no simple easy feature to create a polygon of a bunch of lines delivered with Oracle, you will need to create one yourself.

  Concat_lines might be a start, however, that allows to create a line, then check the endpoint and the starting point: if they are identical, you can create your polygon. Is they are not the same, you can copy the starting at the end point. You can then change the GTYPE and the Ansdo_elem_info so that the entire element becomes a polygon. With a polygon you can use inside effectively to get the results you want. I don't have access to my environment of development here, so can't help you build something right now. But maybe someone else has something already?

  Oh, and after the fact: do not store your polygons in a temporary table, but change your datamodel and begin to use them properly. Temporary tables will be only complicate things more.

• How to find the number of data items in a file written with the ArryToFile function?

  I wrote a table of number in 2 groups of columns in a file using LabWindows/CVI ArrayToFile... Now, if I want to read the file with the FileToArray function so how do I know the number of items in the file. during the time of writing, I know how many elements array to write. But assume that I want the file to be read at a later time, then how to find the number of items in the file, so that I can read the exact number and present it. Thank you all

  Hello

  I start with the second question:

  bytes_read = ReadLine (file_handle, line_buffer, maximum_bytes);

  the second argument is the buffer to store the characters read, so it's an array of characters; It must be large enough to hold maximum_bytes the value NULL, if char [maximum_butes + 1]

  So, obviously the number of lines in your text tiles can be determined in a loop:

  Open the file

  lines = 0;

  While (ReadLine () > 0)

  {

  lines ++;

  }

  Close the file

• How to find the size of the virtual server?

  Hello

  We intend to pass our applications 4 virtual servers has 2 physical servers. In this process, we need to identify the size of the current virtual servers to use as a starting point to configure or add the size in physical server. can anyone provide information on whats stats to be noticed and how to find the size of the current virtual servers?

  Thank you

  Hi Sekhar, there.

  in general, it is a fairly complex task if you want to size the new platform correctly, i.e. not to oversize it and have very low use below, i.e. spend too much on equipment.

  In fact, it's the first thing to consider the level of use of the new platform. Most likely your organization (HW and infrastructure) has targets to a minimum. optimal and maximum usage levels.

  In the case where you do not have this as a starting point, and then you continue with load average and the current peak (CPU, RAM, NW). To these basic lines, you can use the statistics of WLS Admin Console, where the use of CPU and memory statistics are presented since the server was last started. For more detailed statistics, you can use WLDF to capture measures key at regular intervals, and then base your analysis of these data.

  Finally and above all, the size of FS, but I've seen some comments above related to the size of the FS.

  HTH,

• How to find the last pasted paragraphs FMP?

  I'm sticking FMP several objects at once in a file (a file of changes to the sections containing the changebars) in the main text flow. I want a separator line to go at the end of each pasted section, so I try to insert one after the paste operation. But instead of a line between each section, all lines are added at the end of the file, after all the sections. So if there are 3 glued sections at the end of the file are three lines. My code is below, do you know how I could fix this?

  Thank you, Mark

  function copyPasteChanges (doc, chgRange) {}

  Select the section with changebar and copy it.

  doc. TextSelection = chgRange;

  doc. Copy();

  Prepare for the changes doc and paste there the modified section.

  var firstChgPgf = changesDoc.MainFlowInDoc.FirstTextFrameInFlow.LastPgf;

  var changesTloc = new TextLoc (firstChgPgf, Constants.FV_OBJ_END_OFFSET);

  var changesTRange = new TextRange (changesTloc, changesTloc);

  changesDoc.TextSelection = changesTRange;

  changesDoc.Paste ();

  To go at the end of the file again (I think)

  var lastPgf = changesDoc.MainFlowInDoc.FirstTextFrameInFlow.LastPgf;

  var dividerPgf = changesDoc.NewSeriesPgf (lastPgf);

  var TLoc = new TextLoc (dividerPgf, 0);

  changesDoc.AddText (TLoc, '_');

  }

  Hi Mark,

  The problem is that the dough does not occur when you think. The dividing line is added at the end of the file, but are not your actions of dough. Actually, I think that maybe a little random where pasta is produced, because this line:

  var changesTloc = new TextLoc (firstChgPgf, Constants.FV_OBJ_END_OFFSET);

  .. .is does not create a valid text location. You can check this by abandoning the service after:

  changesDoc.TextSelection = changesTRange;

  .. and look at where's the insertion point. It will probably be everywhere where you left it last, because the call is not valid. I can't tell you exactly why, except that it has something to do with the fact that you are using the last paragraph in the stream. There is something weird to try to define a range of full-paragraph text with the last paragraph. I'm sure it's related to how the last TFP in a stream does not show a mark of FMP, but beyond that, I don't know how to do what you're trying to do with the last paragraph.

  Having no knowledge of how do it right, any time I need to do this, I create a paragraph "dummy" at the end of the flow to fill that space strange 'last FMP", then do the work around it. In the end, I just want to remove fake TFP. I don't know if it's a good idea or not, but it's the only way I ever get it to work and it sorts the mirror how you could do this manually in the GUI.

  With this, I modified your script as follows, and it seems to work better. Note that I also modified the logic of how to find the last paragraph of the flow by writing a separate function. Your call to the 'FirstTextFrameInFlow' is OK, unless your doc begins to span several pages and/or begins with several empty pages. The function I wrote ensures that you really the last TFP in the stream.

  I hope this helps.

• 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!

  (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 point of intersection of the two geometry?

  Hello
  Could someone give some suggestions on how to find the point of intersection of the two geometry?
  I need just point. (x, y, z)
  Thank you

  Can you post the full result of geometry returned?

  What you should have as a result:

  MDSYS. SDO_GEOMETRY (2001, 1, NULL, MDSYS.) SDO_ELEM_INFO_ARRAY (1,1,1), MDSYS. SDO_ORDINATE_ARRAY (2.0,2.0))

  Notice the sdo_intersection will use only the sdo_ordinate_array, even if the result is a point! (with the SDO_POINT is NULL.)

  where do you find these x, y, z values of?

  On your other question:

  -using the operator space sdo_relate (with mask = ANYINTERACT) will return in pairs, the result of the intersection of each anyinteracting polygon, line combination.

  -of course, these results will vary from point, multipoint, line or multiline even depending on how the interaction takes place.

  -try to explain a bit more what do you mean 'I want only points to return' of nit.

  You want to upgrade your NB200 with a card 3G?

  Guys might be able to tell if this is possible and could provide a good 3G module
