• InDesign - how to re-enable the button "create a new item of the Index.

  When I was creating topics for my index finger, I saved the document after doing a subject - (because I had created topics yesterday and is not saved and lost all of my work) - when I tried to create a new item of the Index, the button wasn't dark - not active, so I was not able to add more topics to my Index. I rebooted my MacBook Pro (Mac OS X Version 10.6.8) and reopened my InDesign (Version 3.0.1) document and the palette Index box still lacks a button "Create a new item of the Index" assets to allow the action. I do not know how to do this - does anyone have any suggestions?

  I worked on the range of the Index of reference - adding items to the Index with a subject that I had already entered and when I went back to fashion topic, I noticed that the 'Create a new item of the Index' button is enabled - so I think everything is good now. Thanks for the forum.

• The associative arrays, insert, rownum as index loop or not.

  Hi guys,.
  I want to keep this subset of rows around 5000 in a collection / table temporary but don't know how to do it. have not found much on google either.
  the associative array seems good because it has no limit (and it may be more than 5000) and it offers a quick access.
  
  DECLARE
  TYPE assoc_array_str_type IS TABLE OF VARCHAR2 (32) INDEX OF PLS_INTEGER;
  assoc_array_str_type v1.
  BEGIN
  
  (23231) v1: = 10;
  
  -Select distinct rownum, rmnumber made in v1.
  
  END;
  
  I thought that I have use rownum as index but have the feeling that I can't 'load' a set of data both in the associative array. I need to loop and then add one don't I? is there a faster way?

  You can use in bulk to collect:

  declare
     type assoc_array_str_type is table of varchar2(32) index by pls_integer;
     v1 assoc_array_str_type;
  begin
     select ename
     bulk collect into  v1
     from   emp;
  
     dbms_output.put_line('v1(1)='||v1(1));
     dbms_output.put_line('v1(2)='||v1(2));
  end;
  /
  v1(1)=KING
  v1(2)=BLAKE

• Associative arrays

  Quoting docs.oracle.com lines
  
  
  Associative arrays are used to represent sets of data of arbitrary size, with quick search of an individual element without its position in the table and without
  having to loop through all the elements in the array. Here is a small example
  
  DECLARE
  TYPE population_type IS TABLE OF NUMBER INDEX OF VARCHAR2 (64);
  country_population population_type;
  continent_population population_type;
  howmany NUMBER;
  that VARCHAR2 (64);
  BEGIN
  country_population ('Greenland'): = 100000; -Creates the entry
  country_population ('Iceland'): = 750000; -Creates the entry
  -Research associated with a value chain
  howmany: = country_population ('Greenland');
  continent_population ('Australia'): = 30000000;
  continent_population ('Antarctica'): = 1000; -Creates the entry
  continent_population ('Antarctica'): = 1001; -Replaces the previous value
  -Returns "Antarctic" which comes first in alphabetical order.
  who: = continent_population. FIRST;
  -Returns "Australia", which comes last in the alphabetical order.
  who: = continent_population. LAST;
  -Returns the value corresponding to the last key, in this
  -case of the Australia population.
  howmany: = continent_population (continent_population. LAST);
  END;
  /
  
  
  
  my doubt is in what regards the statement "with a quick search of an individual element without its position in the table".can someone give a small relevant example. Therefore the associative arrays is also appropriate for relatively small lookup tables where the collection can be constructed in memory eachtime, a procedure is called? Thanks in advance...

  Think of it as gradually close equivalent to a hash of key/value pairs. When you want to insert an item provide you the key, Oracle axe key to find the entry in the hash table. It doesn't matter if the entry is the first, last, or any other arbitrary position in the table.

  The scope of the variables of the procedure is only the duration of the procedure. They are built when the procedure is called and destroyed when the procedure ends.

  If any associative array created in the procedure must be small to minimize the impact on the performance of the table fill. If the procedure performs complex calculations or ETL one record at a time, it is more efficient to get a value from the array instead of having to re - query a database table for him.

  For example, for the United States, a list of 50 State and their full name abbreviations that can be stored in an associative array and procedure could extract the code of the State of a data element, and quickly find the name of the State of the table. It would be faster than executing a query on the database on a lookup table.

• Associative array in Oracle procedure problem

  Hello
  
  I searched through the internet and this forum and have not been able to solve a problem using the associative array of values in an IN clause.

Unfortunately, I get a ' ORA-21700: object does not exist or is marked for deletion "error when trying to access the table, I filled the table.

  Thanks for the quick response. I looked at the example suggest you and made the following changes. Now, I get an invalid 'Data Type' error on the "column_value SELECT FROM TABLE (CAST (tbl_cat AS tbl_integer))' statement. I must be missing something simple and I can't put my finger on it.

  You did not create a SQL type as I said. tbl_integer is still declared in the PLSQL code you have posted.

  Reread my initial response and look at the example I posted (the very first thing that is done is to create a SQL type).

• INDD 6.0.6 give up when I try to delete the reference in the index

  See also http://forums.Adobe.com/message/4263687 for a discussion of the same problem. Ask here, I'm starting a discussion separate from the same issue affecting someone else (me).

  I am running INDD 6.0.6 on OS X 10.6.8 on a MacBook Pro (2.53 GHz Intel Core 2 Duo). I have a document. INDD that is part of a 50-page book. The document includes an index. The index was imported originally from MS Word (from another user, unknown version). I'm rewriting the index, editing and re-release strongly. I recently discovered that the index is a reference without a target. To be clear, I don't know of a reference in the text of the document. It is an index entry, created by new cross-reference... menu item in the Index pane. There is no target, because when you look at it with forwarding options, there is a first-level topic, but the referenced field (below the Type see also) is empty.

  I can't delete this entry. When I try to delete, INDD crashes. When INDD covers, he warns that the document is may be damaged, and if I try to delete it again, INDD breaks down. If I try to change the referenced field, INDD accepts but does not take into account the change (the closing of the shutter, but the remains of the unchanged index).

  My current solution is to change the theme to ZZZ and add a new index entry (ZZZ: corrupt entry: delete this before shipping), but it is less satisfactory. What can I do to remove the corrupted index cross-reference?

  The biggest problem is that even if you and someone from Adobe to be able to actually understand what that is the problem and that it is, in fact, a bug, there's nothing they can do to help you. There won't be any several bug fixes for CS4. My memory is that he had some bugs in indexing in the first version of CS4 and at least some of them are fixed, then you must install the patch...

• need help in the associative arrays indexed by varchar

  Hi, I wanted to fill an associative array that is indexed by varchar, but I'm confused by incrementing the pointer so that the next lines gets inserted into the next available place.
  sample data:
  type ty_tb_tab_acc is record (account varchar2 (30));
  type ty_tb_indx_acct is table of index ty_tb_tab_acc by varchar2 (35);
  
  cursor sampls_cursor is
  Select an account in sam_tab where the clause goes in here
  
  say that my cursor returns 20 accounts. now, I want these 20 accounts will be inserted in the table associative ty_tb_indx_acct
  How should I buckle and incrment table?
  
  Please share your ideas

  This must be done using SQL. Not the tables or collections or associative arrays.

  SQL is the MOST powerful language, that you have in the Oracle RDBMS. It is faster than PL/SQL, when it comes to crunch data. It is more scalable.

  So why then pull data SQL in PL/SQL (expensive) memory? And then shoot some more SQL data in memory of PL/SQL (expensive)? And then use PL/SQL loop processing to compare the two sets of data?

  SQL can do that very quickly and very efficiently - as it was designed for this specific purpose.

  See the JOIN, INTERSECT , and LESS SQL operations to compare data sets.

• 'Replace the element of the array' replaces not only indexed items

  Hey masters LabView,.

  Fairly new to Labview and I'm trying to sort out how to create a table of images. I know that the total number of images I want in my 'stamp' (not the buffer of LabView), so I'm the initialization of an array of this size. Can I bring this table in a loop For with a shift register, and I want to capture images and write them in the table of the buffe continuously (a comment: I do a circular buffer, but I don't want to implement in LabView, because there a lot of things that I don't need and I will eventually have to the process to be as thin as possible).

  Here's the problem (I assume an implementation, that does not decompose LabView):

  I expect:

  AN element of the array, in the position indicated by the index of the loop [i], is replaced by the image newly caught

  I get:

  All THE elements of the array becomes the image newly caught.

  (I can tell because I taste under the table, grabbing a single image from a constant "Check Array" index - may 7, for example.) But my index of the loop [i] value is 13, and the subsample becomes again the image newly caught.

  What a ridiculous thing I am doing wrong?

  Any help would be greatly appreciated.

  

  Ah, I just noticed something.  Initialize you an array of references at the beginning of your program, but it is a complete picture OF THE SAME REFERENCE: you must call the IMAQ Create in a loop so that you actually get unique references in your table.  You must have a different NAME for each image.

  Thank you Mr President.

  I don't think that the other options are there...

  But it is unlikely that you will need a digital index as 2808000301.

• What is the preferred means of data transmission as a type of record between the nested table of pl/sql program or an associative array

  What is the preferred means of data transmission in the associative array of the nested table record vs

  Choose between Nested Tables and associative arrays

  The two nested tables and associative arrays (formerly index - by tables) use similar index notation, but they have different characteristics when it comes to persistence and ease of passing parameters.

  Nested tables can be stored in a column of data, but can of associative arrays. Nested tables can simplify the SQL operations where you would normally join a single-column table with a larger table.

  Associative arrays are appropriate for relatively small lookup tables where the collection can be constructed in memory whenever a procedure is called or a package is initialized. They are good for the collection of the information volume is unknown beforehand, because there is no fixed limit on their size. Their index values are more flexible, as associative array indices can be negative, can be no sequential and can use values of string instead of numbers.

  PL/SQL automatically converts between the bays of the host and the associative arrays that use values of digital keys. The most effective way to move the collections to and from the database server is to implement data values in associative arrays, and then use these associative arrays with erections in bulk (the FORALL statement or BULK COLLECT clause).
