• Algorithm of Luhn in SQL

  Hello
  
  I'm writing the Luhn-10 algorithm in the SQL (Oracle 10 g). I tried it with reference query below, but it does not work for me. I want to know all of the values where the check digit is 0.
  
  SELECT mod (ROUND (val + 5,-1) - val, 10)
  DE)
  SELECT SUM (CASE WHEN MOD (val2, 2) = 1 THEN)
  BOX WHEN val * 2 > 10 THEN (val * 2) - 9
  Else Val * 2 END
  ELSE VAL END) val
  DE)
  SELECT TO_NUMBER (SUBSTR ('378282246310005 ', rownum, 1)) val, val2 rownum
  of the double
  CONNECT BY LEVEL < = LENGTH('378282246310005')
  order by 2 desc));
  
  Note:-I am able to do this in PL/SQL procedures and functions, however, would be very happy to do this in the SQL query
  
  Logical \Practices\Mod10 said that every 2nd digit on the right on the left should have doubled (or multiply by 2) and the figure has doubled if more than 10, then we need to subtract 9. Finally the sum of all the digits will be divided by 10.
  
  Thanks and greetings

  Hi JAC,

  For a number as below, it returns the value of 4500000000004314 negative, 5500000000000012 etc which are valid numbers as per the

• Loading of several BLOBs with PLSQL - thank you

  Last week, I posted a question (Re: loading multiple BLOBs with PLSQL in desperation asking if any body had a good tutorial to load several blobs.) An answer back to google, I deserved that Mustafa. I did a search and found useful information by Google the word "DBMS_LOB" thank you Billy for the tip. From there, I was able to write an anonymous block that has accomplished what I need, and then asked me to put it in a package, I didn't write a package in some time and must admit to be very rusty on this point, but with the help of a number of you, Toon and Massimiliano (correct use of a Type declaration? ) I was able to get this operational thing.
  
  By way of give something back instead of asking questions all the time, I have included a script below which shows how I approached the group transfer of records with a BLOB column using an external csv file.
  
  Preparation
  1. place a number of documents (I used pdf) in the directory specified by ULOAD_DIR.
  
  2. create a csv file and enter the following text. This can be done by copying the following folders in a Notepad and then file naming EXTERNAL_DATA.csv.
  

  sketch_a.pdf,application/pdf
  sketch_b.pdf,application/pdf
  sketch_c.pdf,application/pdf
  sketch_d.pdf,application/pdf
  sketch_e.pdf,application/pdf
  sketch_f.pdf,application/pdf
  sketch_g.pdf,application/pdf
  sketch_h.pdf,application/pdf
  sketch_i.pdf,application/pdf

  3 run the following script to create objects:
  

  CONNECT SYSTEM/password@XE
  
  CREATE DIRECTORY UPLOAD_DIR AS 'C:\temp';
  
  GRANT READ ON DIRECTORY UPLOAD_DIR TO SCHEMA;
  GRANT WRITE ON DIRECTORY UPLOAD_DIR TO SCHEMA;

      DBMS_LOB.CreateTemporary(p_blob, TRUE);

  END bulk_upload_pkg;
  /

  4. run the following code:
  

  DECLARE
  
    P_REC FMBSITE.BULK_UPLOAD_PKG.GET_FBT_BULK_UPLOAD_REC_TYPE;
    P_BLOB BLOB;
    P_SRCFILE BFILE;
    
  BEGIN
  
    BULK_UPLOAD_PKG.BULK_UPLOAD_PRC
     ( P_REC => P_REC
     , P_BLOB => P_BLOB
     , P_SRCFILE => P_SRCFILE
      );
  
  END;

  5 take a look at the table named TARGET_TABLE, it must contain the attributes in the CSV file and content the UPLOAD_DIR BLOB

• PL/SQL implementation of algorithm of backpack without terminals?

  Hello world

  I am currently working on an algorithm to find the best possible combination according to a lower cost for > = necessary quantity (it's much a similar to a backpack boundless algorithm). For example, if 100 pieces are necessary since the given pool stores (see the data in the table below), I have to come up with a best possible combination. So, in this example, the best choice would be to pull the store_id (A, B, C). I'm currently experimenting with a limited record set 20 who, according to my approach (ie the brute force) who would SELECT (POWER (2.20)) FROM DUAL;  1048576 * 20 iterations and it takes more than 30 seconds using pure PL/SQL. Some information more I play a few checks to see if one store has a required amount then choose the store and out else make a comparison of cross join assuring that the store_id even are not attached then finally if nothing bothers me the quantity required then I'll for a brute force approach. If there is a best way to short circuit the third stage or all have a similar problem and came up with a BETTER solution, please let me know. He could help me and probably many others (SQL approach is available but not PL/SQL). I tried to look for something similar online but has never been able to find any implementation of PL/SQL of the algorithm of bag backpack.

  Sorry, this seems to be a problem trivial backpack to me, since the 'size' different weighted units is the same.

  Then you can simply use a greedy algorithm, taking the cheaper units first.

  This could easily be done using analytical functions.

  The magic number here is 100. It can be replaced by a parameter or variable binding.

  To make it more unambigous in two stores have the same costs, you can extend the order by the analytical function with the value.

  Select

  store_id

  available_qty

  cost_per_unit

  case

  When nvl (sum (available_qty) (cost_per_unit order

  lines between unlimited and 1 preceding)

  0)

  < 100="" then="">

  another "n".

  I have 2 tables: T1 and T2:
  

  with T1 as
  (select 2 FromPeriod, 4 ToPeriod, 10 FromSum, 12 ToSum  from dual)
  select * from t1;
  
  
  with T2 as
  (select 1 FromPeriod, 2 ToPeriod, 9 FromSum, 5 ToSum  from dual
  union all
  select 1 FromPeriod, 3 ToPeriod, 9 FromSum, 4 ToSum  from dual
  union all
  select 2 FromPeriod, 5 ToPeriod, 9 FromSum, 11 ToSum  from dual
  union all
  select 2 FromPeriod, 5 ToPeriod, 11 FromSum, 12 ToSum  from dual)
  select * from t2;

  FromPeriod, ToPeriod are positive whole number without decimal point.
  FromSum, ToSum are positive numbers can have the comma.
  
  Table T1 contains unique in the columns 'FromPeriod-ToPeriod' points, that means that is there is a record where "FromPeriod-ToPeriod" = [2-4], then it is certainly not rendered as "FromPeriod-ToPeriod" = [1-4] keys wich [2-4] period, such a thing is not possible in table P1, it contains only unique periods that do not touch. Then the records with periods [2-4], [5-6] are ok in there.
  But table T2 allows periods affecting somehow. You can see that T2 contains "FromPeriod-ToPeriod" = [1-2] and also [1-3] that touch each other.
  
  We can look at the two tables T1 and T2 as rectangles where X - axis is the values of the axes and the "FromPeriod-ToPeriod" is [FromSum, ToSum].
  I need sql/plsql algorithm that returns true if the rectangle of table T1 is discovered/filled with rectangles in table T2. If the rectangle in T1 is completely filled or even more filled than necessary, then algorithm should return true. If even a small neighborhood in rectangle T1 is not filled by rectangles in T2, then the algorithm must return false.
  
  As see you in the sample data, T1 has a rectangle: [2-4; 10-12] T2 contains 4 mentions that fill/overdraw this area defined by T1. So for the moment the algorithm must return true.
  
  I do not know how to write effective elsewhere such algorithm, can you help me?
  
  --
  At the moment I only came with such algorithm/query:
  
  Test1: this test should return true:

  --query: is rectangle [2-4;10-12] filled? -Yes.
  with T2 as
  (select 1 FromPeriod, 2 ToPeriod, 9 FromSum, 5 ToSum  from dual
  union all
  select 1 FromPeriod, 3 ToPeriod, 9 FromSum, 4 ToSum  from dual
  union all
  select 2 FromPeriod, 5 ToPeriod, 9 FromSum, 11 ToSum  from dual
  union all
  select 2 FromPeriod, 5 ToPeriod, 11 FromSum, 12 ToSum  from dual)
  select * from t2
  where (2 <= ToPeriod and 4 >= FromPeriod) -- x-axes overlapping
  and (10 <= ToSum and 12 >= FromSum)--y-axes overlapping
  ;--2 rows
  
  --
  
  2     5     9     11
  2     5     11     12

  I takes as input the T1 table horizontal axes (2, [4]) and research data table T2 that affect this horizontal axes, also the value axes is compared. But how then? There are 2 files, but it can give 10 stores overlap in the periods and amounts. How to determine now that rectange T1 is filled?
  
  Test2: This case should return false:

  --query: is rectangle [2-4;10-12] filled? -No.
  with T2 as
  (select 1 FromPeriod, 2 ToPeriod, 9 FromSum, 4 ToSum  from dual
  union all
  select 1 FromPeriod, 3 ToPeriod, 9 FromSum, 4 ToSum  from dual
  union all
  select 2 FromPeriod, 4 ToPeriod, 9 FromSum, 11 ToSum  from dual
  union all
  select 2 FromPeriod, 5 ToPeriod, 13 FromSum, 13 ToSum  from dual)
  select * from t2
  where (2 <= ToPeriod and 4 >= FromPeriod) -- x-axes overlapping
  and (10 <= ToSum and 12 >= FromSum)--y-axes overlapping
  ;--1 row.
  
  2     4     9     11

  Charles,

  I see 2 choices, but none is likely to evolve very well. The first can be with SQL - subdivision T1 into unit squares and see if everything not covered by T2:

  with T1 as
  (select 2 FromPeriod, 4 ToPeriod, 10.1 FromSum, 12 ToSum  from dual)
  , T1X as
  (select (FromPeriod+level)-1 as Period from T1 connect by level <= (ToPeriod-FromPeriod)+1)
  , T1Y as
  (select (FromSum+level*.01)-.01 as Summ from T1 connect by level <= (ToSum-FromSum+.01)/.01)
  , T1XY as (select Period,Summ from T1X,T1Y)
  ,T2 as
  (select 1 FromPeriod, 2 ToPeriod, 9.99 FromSum, 10.1 ToSum  from dual--satisfies sub-region [(2,2);(10.1,10.1)]
  union all
  select 1 FromPeriod, 2 ToPeriod, 9.99 FromSum, 10.11 ToSum  from dual--now satisfied sub-regions: [(2,2);(10.1,10.11)
  union all
  select 2 FromPeriod, 2 ToPeriod, 10 FromSum, 12.01 ToSum  from dual--now satisfied sub-regions: [(2,2);(10.1,12)
  union all
  select 3 FromPeriod, 4 ToPeriod, 10 FromSum, 11.99 ToSum  from dual--now satisfied sub-regions: [(2,2);(10.1,12)],[(3,4);(10,11.99)]
  union all
  select 4 FromPeriod, 4 ToPeriod, 10 FromSum, 13 ToSum  from dual--now satisfied sub-regions: all filled, return true
  )
  select Period,Summ from T1XY
  where not exists (
  select 1
  from T2
  where T2.FromPeriod<=T1XY.Period
  and   T2.ToPeriod>=T1XY.Period
  and   T2.FromSum<=T1XY.Summ
  and   T2.ToSum>=T1XY.Summ
  )
  ;
  

  The second option is more inspiring you described, using a recursive algorithm to subdivide the T1 into small rectangles for each rectangle in T2. For example:

  X(1)={[a,b;c,d]}
  
  Y={[e,f;g,h];[i,j;k,l]}
  
  X(2)={[a,e;c,g];[e,f;c,g];[f,b;c,g];[a,e;g,h];[f,b;g,h];[a,e;h,d];[e,f;h,d];[f,b;h,d]}
  or
  X(2)={[a,b;c,g];[a,b;h,d];[a,e;c,d];[f,b;c,d]}  -- this gives some overlap, but fewer rectangles and the algorithm still works.
  
  You would have to refine it to handle partial overlaps correctly, then drop areas that don't have a positive area. If
  X(2) becomes empty then it is fully covered. It might be most efficient to sort T2 in order of descending area.
  

  Kind regards

• Office distance, MSSQL and TLS 1.0 and RC4 encryption algorithms

  Currently, SSL Labs suggests that SSL RC4 encryption algorithms are low, and that to always mitigate the attack of the BEAST in older clients, TLS 1.0 can be disabled.

  I've read the threads which set out that MS SQL server had problems when SSL 3.0 and TLS 1.0 have been disabled, and also this turning off TLS 1.0 would break Remote Desktop (which this thread seems State requires TLS 1.0 and RC4 ciphers: https://msdn.microsoft.com/en-us/library/aa383015%28v=vs.85%29.aspx)

  See also:

  Is it possible to have a Windows Server 2012, which is fully patched, rely on a plu TLS encryption algorithm versions than 1.0 and the MCG (or other)?

  If the answer is that TLS 1.0 and RC4 must be enabled for authentication of network layer, can offer you a better order of practical cipher who would score high enough on ssl labs?

  SSL3.0 and TLS 1.0 can be turned off the coast and have always start MS SQL 2012 (not configured to use SSL connections/sql ssl certificate)?

  Thanks for any input that you are able to give.

• Change to AES256 encryption algorithm

  Hello

  RDBMS - 11.2.0.3

  We have about 40 tablespaces encrypted using AES128. We need to chage AES256 encryption algorithm.

  Would like to know if any body he sings? How? What are the effort involved?

  concerning

  Concerning

  http://docs.Oracle.com/CD/E11882_01/network.112/e40393/asotrans.htm#ASOAG620

  "......... You cannot encrypt an existing table. However, you can import data in a tablespace that is encrypted by using the Oracle Data Pump utility. You can also use SQL commands, such as CREATE TABLE...AS SELECT... or ALTER TABLE...MOVE... to move the data in an encrypted tablespace. The CREATE TABLE...AS SELECT... command allows you to create a table to an existing table. The ALTER TABLE...MOVE... command is used to move a table in encrypted storage space... »

• How to update table pl SQL by using the loop

  Assuming I don't have only one table: members_tbl which columns are: SN, FN, DB, IDDBL, FLAG, DBLCRIT

  I need to update the table if certain conditions are OK with this algorithm:

  id_dup: = 1;

  (I, 1 to Nrow (members_tbl)) THEN

  {

  ((I + 1) J to Nrow (members_tbl)) THEN

  {

  IF (members_tbl (i) .iddbl IS NULL) THEN

  members_tbl (i) .iddbl: = id_dup

  IF (((members_tbl (i). DB is members_tbl (j). DB)

  AND (UTL_MATCH.jaro_winkler_similarity (members_tbl (i). SN, members_tbl (j). (SN) > 80)

  AND (UTL_MATCH.jaro_winkler_similarity (members_tbl (i). FN, members_tbl (j). FN) > 80))

  AND (members_tbl (j) .iddbl IS NULL)) THEN

  {

  members_tbl (j) .iddbl: = id_dup;

  members_tbl (i) .flag: = 1;

  members_tbl (j) .flag: = 1;

  members_tbl (i) .dblcrit: = 1;

  members_tbl (j) .dblcrit: = 1;

  }

  }

  id_dup: = id_dup + 1;

  }

  Is there a way to write this algorithm in a pl/sql procedure? I'm relatively new to PL/SQL, and I've never written a stored procedure.

  IDDBL is a NUMBER yet, there may be several duplicate rows.  How you expect store multiple values in a single issue?

  SQL > select m.idm
  2, m.sname
  3, m.fname
  4, m.dbirth
  5, listagg (m2.idm, ',') Group (order of m2.idm) as dups
  members_tbl 6 m
  7 left join external members_tbl m2 (m.idm! = m2.idm)
  8 and m.dbirth = m2.dbirth

• Oracle Sql Developer is very slow

  Hello

  I ' have a big problem with SQL developer. We have a lot of databases on the connections.xml (about 1600 databases Oracle) file. When we start SQL developer, it took about 10 minutes to open. Can what solutions we use to open this application more quickly?

  We have already tried to add this line to the sqldeveloper.conf file:

  AddVMOption - Sqldev.tnsping = false

  But we see no change.

  We must have a solution to fix this problem because 10 minutes is much much time to work properly.

  What makes it truly Developer SQL in start up to put so much time?

  Best regards.

  A bug has been noted, as stated in the post 15 of this discussion. That's the good news, because there was no prior bug in the system for that matter.

  There is a performance problem, of course, since the additional startup due to connections time more seems to increase exponentially, rather than (at most) linearly as could be expected.  In other words, on my system...

  1. 23 connections takes no extra time measurable.

  2. 575 connections takes 13 seconds.

  3. 1150 connections takes 53 seconds.

  4. you claim that 1600 connections on your system takes about 10 minutes.

  The bug will be reviewed by the developer and probably a better algorithm can be used, or the treatment in question may be delayed or run lazily so it won't slow down the startup.  I don't know when this will happen, however.  If you need urgently, you can follow up with Oracle Support to get a bug associated client id, track progress and present evidence for why it should have priority.

  Kind regards

• data type for astromical algorithms

  Hello everyone.

  IM using Oracle 12 g of data.

  I have to face a new application where I have to develop a large number of astronomical algorithms, normally calculated them on the speed of the planets, astronomical positions and so forth.

  These algorithms usually have a large number of decimal place, between 10 and 20.

  So, Im trying to find the best types of data, because the accuracy is a must. And these are my doubts...

  Read the tutorial of Oracle it say that the number data type contains all the other subclass of numbers. For example, as I understand it, the integer data type is only one type of data number with some restrictions.

  My question is:

  If I declare a variable as number, this variable will have the same accuracy as a variable declared as binary_double? For example

  Declare

  x number; -Without defining the decimal scale in this way, it can accept the range possible decimal

  x BINARY_DOUBLE:-that class will have the same accuracy as the number of x?

  What is the best way to declare these vars?  by order of accuracy, storage and speed is not so important in this application.

  Regards to all the world and thanks in advance.

  Use the NUMBER unless you have a specific reason NOT to use it.

  See the built-in data types in the doc of the SQL language

  http://docs.Oracle.com/CD/B28359_01/server.111/b28286/sql_elements001.htm#i54330

  2

  NUMBER[ (p [, s]) ]

  Number having precision p and scale s . Precision p may vary from 1 to 38. Wide s can vary from-84 to 127. Precision and scale are in decimal digits. A NUMBER value requires 1 to 22 bytes.

• SQL dev. "quota exceeded... space. »

  I load a data in data SQL DEV career. and run the k-means clustering algorithm. I can load the data successfully, but the model build and gives me below error.
  space quota exceeded for table space 'data mining '.
  How can I solve the space problems
  I run k-means on these data successfully in the MDGS.
  
  Published by: Nasiri Mahdi on April 15, 2013 23:01

  Hi Nasiri,
  I have to assume that the table space assigned to the user account is "data mining".
  It seems that the user account doesn't have an allocation of adequate space.
  See the link below for more information on this type of problem.
  ORA-01536: space quota exceeded for tablespace 'USERS '.
  Thank you, Mark

  I have been using SQL Developer for some time and had initially had problems in the past with memory consuption high when I use this tool.
  I have received and applied the advice from this forum, and while he had helped a little, the majority of high memory consumption remains a problem.
  
  Finally, I had more time to dig around and try to isolate exactly where the problem seems to come from and here's what I found.
  
  (* 1) * I removed functionality updates checking
  (* 2) * I turned it off a lot of the extensions with the exception of Navigator DBA, SQL monitoring in real time, search bar, and extracts.
  (* 3) * when I start a fresh SQL Developer Session and initiate an Oracle application connection consumes about 148 meg RAM fo
  (* 4) * when I opened my Windows Task Manager and watch the memory allocated to SQL Developer, I noticed it goes back to when I move my mouse over the SQL Developer tool and when I run the menu about 5 k a second or so and the memory never came out in the system.
  (* 5) * when I run a great SQL in the memory grid jumps by about 100 meg or more and will continue to do so whenever I repeat the SQL until the SQL Developer consumes about 748 meg of RAM.
  (* 6) * 748 Meg of RAM seems to be the number when the SQL Developer (with an Oracle connection) is more continues to consume more and then not return memory to the system.
  
  Is it possible to have a SQL Developer automatically clear it's using active memory without closing down then restarting him?
  Why SQL Developer continues to consume memory more and more just to move your mouse or navigation in the menus?
  
  Here is my speech in detail;

  Hi Tom,

  Memory consumption you observe is characteristic of the machine virtual Java and algorithm of garbage collection that he uses. There are a few tricks you can use to improve the deallocation of memory in the JAVA virtual machine. See the following topics:
  Re: Reduce the footprint memory SQLDeveloper with JDK 1.7
  Re: Memory leak or bad Java Garbage Collector

  In addition, it is best to follow the size of the heap of the JVM and memory via a memory profiler. The Task Manager is supposed to these exaggerate.

  Kind regards

• Same algorithm in function and procedure so that one will be better?

  Why is better to pl sql function calculates a value instead of the procedure?
  If I apply the same algorithm in function and procedure while one will perform better?

  Siddharth Singh says:
  Oracle documentation

  http://docs.Oracle.com/CD/B10500_01/AppDev.920/a96624/08_subs.htm

  This:

  Generally, you use a procedure to perform an action and a function to calculate a value.

  Does not mean that the function are better to calculate a value, but you usually use functions to calculate a value.

  Usually, a function is can be more useful if you plan to use in a query.
  that is to say:

  SELECT myfunc(col1) from mytable;
  

  That you can't do with a procedure. Functions are also usually limited to the returning a single value, while procedures may have several OUTPUT parameters.

  Kind regards.
  Al
