• If the INSTR function will not use the INDEX o?

  Hi all
  
  
  I have a querry as

      Select * from Tab1 Where Instr(Tab1.Col1,'XX') >0 ;

  Is simple index on column Col1. If we use the index will be used or full table scan will happen in this scenario?

• What is the index of modularity?

    Index of modularity In "The Labview Style Book", p 13.
   
       1.1 equation
  Modularity Index = (user # screw / total number of nodes) * 100

  Way?
  

  It is a measure that is the VI Analyzer.  Something to assess quantitatively so your VI is very modular or not.  It looks at the number of under VI used compared to the overall size of the program (including the total number of nodes).  If you use enough of the Subvi, this means that you probably code modular and will have a higher index.  If you put all your code in a large diagram and fail to use Subvi to break it down into smaller modules, then your index of modularity will be close to zero.

• What is the use of the DUMP function

  Hi friends,
  
  What is the Dump function? What is the use of dump? where can I use dump?
  
  ex:
  
  Select (sysdate) dump of double;
  
  Please expline with good example,
  
  
  By,.
  Symph.

  Sometimes you can have data in your database that you expect to be returned or excluded by a query, but you do not know why it does not work as expected. With the help of DUMP, you can examine the contents of the byte-by-byte data to help identify issues...

  SQL> with t as (select '&data' as dta from dual)
    2  --
    3  -- end of test data
    4  --
    5  select dta, dump(dta), dump(dta,16) from t;
  Enter value for data: Fred Smith
  old   1: with t as (select '&data' as dta from dual)
  new   1: with t as (select 'Fred Smith' as dta from dual)
  
  DTA
  ----------
  DUMP(DTA)
  ---------------------------------------------------------
  DUMP(DTA,16)
  ---------------------------------------------------------
  Fred Smith
  Typ=96 Len=10: 70,114,101,100,255,83,109,105,116,104
  Typ=96 Len=10: 46,72,65,64,ff,53,6d,69,74,68
  

  So my entry of "Fred Smith" looks like it's just two names separated by a space, but in reality in this example, the 'space' is the character ascii 255 (FF hex). This can be seen in the DUMP information. If it's data to my database, I would now be able to determine why, for example, I wasn't getting it back in my query when you query for "Fred Smith" by using a space character.

  There are other options as well, for example, to examine the character set...

  SQL> select dump('Fred Smith',1017) from dual;
  
  DUMP('FREDSMITH',1017)
  ------------------------------------------------------------
  Typ=96 Len=10 CharacterSet=WE8MSWIN1252: F,r,e,d, ,S,m,i,t,h
  
  SQL> select dump('Fred Smith',1016) from dual;
  
  DUMP('FREDSMITH',1016)
  ----------------------------------------------------------------------
  Typ=96 Len=10 CharacterSet=WE8MSWIN1252: 46,72,65,64,20,53,6d,69,74,68
  

  Take the result of the DUMP function you can use for all sorts of things based on what your needs are... example...

  In binary or hex string conversion...

  A slight correction to the post of odie. I think you mean min max to replicate the primary function of access, but see below for sure. So:

  min(upper(trim(tre.dname))) keep (dense_rank first order by tre.gcusno) as dname_std
  

  user10860953 wrote: how it ignores null values?

  The min and max functions automatically ignores nulls, so if there is a null value in tre.dname, it will not be returned, unless all values are null. For example:

• What is the purpose of the function Array Index in the example attached?

  Hello

  I'm fighting with the Array Index function. I found the attached VI on the OR site which was exactly what I wanted to do, but rather than simply accept that it works and use it, I wanted to understand.

  What is the purpose of the function Index of table inside the while loop? If I put a probe on part and on the other, the values are the same, but if I remove the service and connect directly to the > function, I get an error.

  I do not understand the tables but I don't understand what is happening here. Any help would be appreciated gratefully.

  Thanks in advance.

  

  It is just picking the first reading of the table in the waveform.  If it's good enough (I'd take at least the average of N samples), why not cela?

  

• CVI 2013 SP1 - function calls repeated with pointer on a variable array parameter causes a shift of the index

  I have some functions will be pointers as parameter and CVI 2012 SP1, they work as before without problems but with CVI 2013 SP1 they are now incorrect.

  Here the description of what is happening - I found a cure, but a duty adopt the old code and I think it's clear that nobody don't "captures" all lines in a 'big old code' which are affected (maybe):

  I have functions

  'function_XYZ(int *p_paraArr) '.

  with 'p_paraArr' as pointers on a table (int).

  Suppose I have another function

  "fct_TOP (void)".

  where is a local array variable which is inizialized by

  "int TheArray [25] = {0};

  and inside of this "TOP"-function-body I call a function ".

  "function_XYZ (TheArray).

  There are no complains of the compiler (CVI 2012 or 2013) and the code works (but the CVI 2013 only once!).

  But if I put 'fct_TOP' loop I have a lag in the "TheArray' -memory.  (The loop surrounds the function "TOP"! "")

  This means that the result "TheArray" obtained from "function_XYZ (TheArray)" starts at index '1' not on the index '0' - as the first time that the function "function_XYZ (TheArray)" was performed. ".

  The solution is:

  I only replaced

  "function_XYZ (TheArray)" (<1>)

  by

  "function_XYZ (&(TheArray[0]))" (<2>)

  overall the program now works every time (in the whole loop)-the first time (in the loop).

  In the second version (<2>) everything is necessary to "work well":

  The '&' and parentheses "(...)", which contains the element that may be designated by the '& '.

  And I hope that you believe me: I've tested several times, it was only "little" change that solved the problem.

  So it seems that the ICB 2013 (SP1) is a kind of internal offset index by a repeated execution of the

  "function_XYZ (TheArray).

  but I don't know how or why but I see in debug mode by observing the expected against the values in the table received!

  At the first time the (implicit) internal index of 'TheArray' is '0', but the following times (during the execution of the loop) the internal index passes to '1' (seen in the debugger because that all the expected values were shiftet like that!).

  So there's an explicit index in the table ("function_XYZ (&(TheArray[0]))") necessary to make the first time of this clear code execution.

  There are some good improvements in 2013 CVI (SP1) and I like this environment more than the 2012 version - but:

  There are other "changes" also, in the compiler (or linker...?) that are more rigid than "in ancient times.

  The problem of this kind of error is always the 'old code '!

  It is expected of such behavior.

  The compiler/linker do not complain (a complaint would be good!) writing but he made this mistake (in a loop).

  By the way: my 'compilation Options' are set to 'Extended' (without change in the "..." ("- button - Options) and that all of the boxes, except the" OpenMP_support "-box are checked!"» So I think that I put the very rigid compiler - maybe there are some «...» ' - button - settings to get rid of this problem, but I have not found them/it.

  My request:

  -Check the stiffer compiler by the need of an explicit index

  - or switch to the 'old' behavior with "function_XYZ (TheArray)" always refers to implicit index '0' of the element "TheArray". "."

  Thank you for your messages, comments and suggestions.

  -As I wrote before - maybe it's the style of programming or error"self made"... maybe...
  .. But if I replace 'function_XYZ (TheArray)' by "function_XYZ (&(TheArray[0]))" and
  then it works... Why so and not, if bothe the same? ...

  But as long as I do not post sample code, nobody is going to accept - I accept it. So consider this post more as an allusion to the fact that of the LW/CVI 2012-2013 LW/CVI more changed than just the LW - GUI or certain features: the compiler changed its 'way to'... or almost.

  For this problem, I think that I will use the solution 'use no implicit and explicit pointers'.
  Who should be a good idea taking into account
      http://forums.NI.com/T5/LabWindows-CVI/fatal-run-time-error-dereference-of-out-of-bounds-pointer/TD-...

• Invalidation of the index based on a function because the recompilation

  Hello

  one of our customers has two indices according to the functions that fall under the State "off" in some situations. After looking more closely at the situation, there are some things that my opinion are different from what I expected of a function-based index. Because I am unable to find anything about either on metalink (or I'm not asking the right question) I would appreciate a second opinion of you.

  To keep things simple, I gave an example to illustrate the behavior. I use Oracle 12.1.0.2, although it can also be reproduced on versions 10.2 and 11.2.

  It's my environment and three parameters that I find relevant to the discussion:

  SQL> select banner from v$version;
  
  BANNER
  ----------------------------------------------------------------------------
  
  Oracle Database 12c Enterprise Edition Release 12.1.0.2.0 - 64bit Production
  PL/SQL Release 12.1.0.2.0 - Production
  CORE    12.1.0.2.0      Production
  TNS for Linux: Version 12.1.0.2.0 - Production
  NLSRTL Version 12.1.0.2.0 - Production
  
  SQL> show parameter remote_dependencies
  
  NAME                                 TYPE        VALUE
  ------------------------------------ ----------- ----------
  remote_dependencies_mode             string      TIMESTAMP
  
  SQL> show parameter query_rewrite
  
  NAME                                 TYPE        VALUE
  ------------------------------------ ----------- -------------
  query_rewrite_enabled                string      TRUE
  query_rewrite_integrity              string      enforced
  

  Test case:

  SQL> CREATE OR REPLACE FUNCTION f1 (p_string IN VARCHAR2)
    2  RETURN VARCHAR2
    3  DETERMINISTIC
    4  IS
    5  BEGIN
    6    RETURN lower(p_string);
    7  END f1;
    8  /
  
  Function created.
  
  SQL> CREATE TABLE tmp_t1 (a_string VARCHAR2(10));
  
  Table created.
  
  SQL> INSERT INTO tmp_t1 VALUES ('a');
  
  1 row created.
  
  SQL> COMMIT;
  
  Commit complete.
  
  SQL> CREATE INDEX x1_tmp_t1 ON tmp_t1(f1(a_string));
  
  Index created.
  
  SQL> set linesize 80;
  SQL> column index_name format a10;
  SQL> SELECT index_name, index_type, status, funcidx_status
    2    FROM user_indexes;
  
  INDEX_NAME INDEX_TYPE                  STATUS   FUNCIDX_
  ---------- --------------------------- -------- --------
  X1_TMP_T1  FUNCTION-BASED NORMAL       VALID    ENABLED
  

  We have our table and our based on an index function which basically converts the values to lowercase. From here on things, download a little weird. What happens with the index based on a function if the underlying function is recompiled? I always thought (and which is also stated in the Concepts and the use of function index (Doc ID 66277.1)) that the index would change its status to "disabled". Here is an excerpt of the said Doc ID:

  The index depends on the State of the PL/SQL function. The index can be

  struck down or rendered useless by changes to the function. The index is marked

  People with DISABILITIES, if he is brought to the function or function is re-created.

  The timestamp of the function is used to validate the index.

  To allow the index after it is created, the function if the signature of the

  the function is identical to the front:

  ALTER INDEX ENABLE;

  If the signature of functions is changed, to make the changes effective

  in the index, the index must be renewed to make it valid.

  ALTER INDEX REBUILD.

  It seems that this is not the case, as the index remains valid and activate.

  SQL> alter function f1 compile;
  
  Function altered.
  
  SQL> SELECT index_name, index_type, status, funcidx_status
    2    FROM user_indexes;
  
  INDEX_NAME INDEX_TYPE                  STATUS   FUNCIDX_
  ---------- --------------------------- -------- --------
  X1_TMP_T1  FUNCTION-BASED NORMAL       VALID    ENABLED
  

  OK, explicitly recompiling function F1 single timestamp changed. What if we replace the function completely and we change the output of the function - for example we will switch from a LOWER function to SUPERIOR function in the body of the F1. Again, it is change that I thought would be not only to disable the index based on a function, but also force its reconstruction. At least that is my understanding of the explanation in Doc ID).

  SQL> CREATE OR REPLACE FUNCTION f1 (p_string IN VARCHAR2)
    2  RETURN VARCHAR2
    3  DETERMINISTIC
    4  IS
    5  BEGIN
    6    RETURN UPPER(p_string);
    7  END f1;
    8  /
  
  Function created.
  
  SQL> SELECT index_name, index_type, status, funcidx_status
    2    FROM user_indexes;
  
  INDEX_NAME INDEX_TYPE                  STATUS   FUNCIDX_
  ---------- --------------------------- -------- --------
  X1_TMP_T1  FUNCTION-BASED NORMAL       VALID    ENABLED
  
  

  Should not be. Because of the function "create or replace" F1 never go through a "invalid" phase which may be necessary for index becomes unusable? What about queries on the TMP_T1 table? Does optimizer always uses access index or not? What about the results?

  SQL> EXPLAIN PLAN SET statement_id='s1' FOR
    2  SELECT a_string, f1(a_string) as f1_a_string, f1('a') as f1_literal
    3    FROM tmp_t1
    4   WHERE f1(a_string) = 'a';
  
  Explained.
  
  SQL> SELECT * from table(dbms_xplan.display(statement_id=>'s1'));
  
  PLAN_TABLE_OUTPUT                                                                                                   
  ------------------------------------------------------------------------------------------------------------------------
  Plan hash value: 3133804460                                                                                         
                                                                                                                      
  -------------------------------------------------------------------------------------------------                   
  | Id  | Operation                           | Name      | Rows  | Bytes | Cost (%CPU)| Time     |                   
  -------------------------------------------------------------------------------------------------                   
  |   0 | SELECT STATEMENT                    |           |     1 |  2024 |     2   (0)| 00:00:01 |                   
  |   1 |  TABLE ACCESS BY INDEX ROWID BATCHED| TMP_T1    |     1 |  2024 |     2   (0)| 00:00:01 |                   
  |*  2 |   INDEX RANGE SCAN                  | X1_TMP_T1 |     1 |       |     1   (0)| 00:00:01 |                   
  -------------------------------------------------------------------------------------------------
  

  The index is used by the optimizer, see the results.

  SQL> column f1_a_string format a15;
  SQL> column f1_literal format a15;
  SQL> SELECT a_string, f1(a_string) as f1_a_string, f1('a') as f1_literal
    2    FROM tmp_t1
    3   WHERE f1(a_string) = 'a';
  
  A_STRING   F1_A_STRING     F1_LITERAL
  ---------- --------------- ---------------
  a          a               A
  

  A_STRING = value in the table

  F1_A_STRING = value of f1 (a_string) but the value is not evaluated because it comes from an index, so tiny value (remember, at the time index created the function returned small values)

  F1_LITERAL = value of the function f1 newly evaluated, using literal instead of the value in the table.

  Predicate f1 (a_string) = 'a' should return no rows because no character uppercase is equivalent to "a". Query with f1 (a_string) = 'A' should return a line, but it doesn't.

  SQL> SELECT a_string, f1(a_string) as f1_a_string, f1('a') as f1_literal
    2    FROM tmp_t1
    3   WHERE f1(a_string) = 'A';
  
  no rows selected
  

  Anyone know if this is an expected behavior? And, is it possible to disable the index based on a function whenever the underlying function signature is changed? The parameter query_rewrite_integrity = applied from

  DOC-ID 66277.1 does not seem to do the trick:

  (c) session variables

  ~~~~~~~~~~~~~~~~~~~~

  QUERY_REWRITE_ENABLED (true, false),

  QUERY_REWRITE_INTEGRITY (confidence, forced, stale_tolerated)

  expressions using SQL, user defined functions functions.

  Kind regards

  From the Manual 11.2 ( https://docs.oracle.com/cd/E11882_01/appdev.112/e41502/adfns_indexes.htm#ADFNS254 )

  "If you change the semantics of a DETERMINISTIC run and recompile, then you must manually rebuild all addicts depending on index and materialized views." Otherwise, they report results for the previous version of the function. »

  This note is not that I made my initial comment well - which was based on an incorrect memory the relationship between function-oriented and autonomous pl/sql functions, so I won't try to explain it. In fact, I went back to Oracle 8i practice to see if something had changed between yesterday and today and found that I had described exactly the behavior that the OP has been seeing. It's the way it is supposed to be.

• What is the function local folders are used in TB? When should I use/non use?

  What is the 'local folders' function does TB? How is it related to the 'archives '. 2015 archives disappear after 2015 or 2016 pop up? Why not just add subfolders Archives rather than 2015 Archives? Documentation on these topics?

  Archives and local folders are not related. You can create an Archive folder under "Local folders" account however.
