• How to get a list of the tables more fragmented in Oracle?

  Is there a SQL on how to get a list of the tables more fragmented in the Oracle DBMS?

  Update the statistics on the table and try this, you should see very fragmented tables upstairs with high wasted_space.

  select table_name,round((blocks*8),2) "size (kb)" ,
                              round((num_rows*avg_row_len/1024),2) "actual_data (kb)",
                              (round((blocks*8),2) - round((num_rows*avg_row_len/1024),2)) "wasted_space (kb)"
  from dba_tables
  where (round((blocks*8),2) > round((num_rows*avg_row_len/1024),2))
  order by 4 desc
  

  I changed the query a little because the ORDER BY will not work if we concat | ' Ko ' with the column because this makes the output a character column data.
  And added a WHERE condition to see that these tables where the total size is greater than the actual size of data.

  You simply create separate locations for each segment. If we can assume that all segments have the same length, the code can be considerably simplified, for example as follows. If we cannot assume that, you can try changing my previous code. Shouldn't be too difficult.

• How to make the query more efficient

  Hi all

  I use the following query in my app that works very well. Although I'm not an expert in PL/SQL, can someone please suggest how can I make the query more efficient? Because I use the same contract for every query table. Only difference is that in the name of the condition column. Again I am showing same column comments for each request. I was wondering if I can join these 3 and do 1 single request if possible

  DECLARE
  v_CONTRACTNO varchar2(100);
  v_CHILDCONTRACTNO varchar2(100);
  v_SOURCESYSTEM varchar2(100);
  
  BEGIN
  begin
  SELECT comments
  into v_CONTRACTNO
  from user_col_comments
    where TABLE_NAME = 'CONTRACT'
  and COLUMN_NAME = 'CONTRACTNO';
  end;
  begin
  SELECT comments
  into v_CHILDCONTRACTNO
  from user_col_comments
    where TABLE_NAME = 'CONTRACT'
  and COLUMN_NAME = 'CHILDCONTRACTNO';
  end;
  begin
  SELECT comments
  into v_SOURCESYSTEM
  from user_col_comments
    where TABLE_NAME = 'CONTRACT'
  and COLUMN_NAME = 'SOURCESYSTEM';
  end;

  Of course, you can get all 3 values in a query.  Here's one way:

  SELECT contractno, childcontractno, sourcesystem

  IN v_contractno, v_childcontractno, v_sourcesystem

  Of user_col_comments

  PIVOT (MIN (comments)

  FOR column_name IN ('CONTRACTNO' AS contractno

  'CHILDCONTRACTNO' AS childcontractno

  'SOURCESYSTEM' AS sourcesystem

  )

  )

  WHERE table_name = 'CONTRACT '.

  ;

  But I doubt that it makes things very slow.   If your PL/SQL performance is poor, I suspect that the cause is somewhere that you haven't posted.

  2 Select regexp_substr (txt,'[^.] +') part_1,.
  3 regexp_substr (txt,'[^.] +', 1, 2) part_2,.

• Concatenate and split the string

  Hi all
  
  Is there some how we can split the string like this "1 | ~ | Diego | Maradona | ~ | Footballer | The Argentina.
  
  in the table of 3 elements: '1', ' Diego | Maradona', ' football '. The Argentina.
  
  Here is my code

  public static void main(String args[]){
            System.out.println("========USE SPLIT========== " );
                 String data = "1 |~| Diego|Maradona |~| Footballer|Argentina";
               String[] items = data.split(" |~| ");
               for (String item : items)
               {
                    System.out.println("item = " + item);
               }
               StringTokenizer tok = new StringTokenizer(data," |~| ");
               System.out.println("========USE TOKENIZER========== " );
               while(tok.hasMoreElements()){
                    System.out.println("item = " + tok.nextToken());
               }
            
       }

  and put it is:
  = USE SPLIT =.
  Item = 1
  Item = |
  Item = |
  Item = Diego | Maradona
  Item = |
  Item = |
  Item = football | Argentina
  = USE TOKENIZE =.
  Item = 1
  Item = Diego
  Item = Maradona
  Item = footballer
  Item = Argentina

  Split() takes a regular expression. ' | ' has a special meaning in regular expressions.

  Try to use

  " \\|~\\| "
  

  as the argument of split()

• Run (or re-run) orders in the SQL * more buffer

  I'm confused about sql / command. by defination, it run (or re-run) orders in the SQL * more buffer. How do I know if it execete or re - run a command?
  for example, I run a select statement, seems that I have to type / for the result. When I run a create table statement, it seems to run twice with / and table I is error.
  
  Someone could clearify when must - be used and when not to use it.

  As suggested Aman, that's the difference between a pl/sql block and a SQL statement (DDL or DML).

  The semicolon is therefore not a part of SQL when you enter a statement SQL, SQL * Plus knows and will execute the statement as soon as she sees a point comma (which ends with the statement), or slash (run the buffer).

  But a semicolon is a pl/sql statement terminator. So when you enter a pl/sql block, SQL * Plus keeps accepting lines of code until you have finished and then send the entire block to the database when you type a slash. This is also true when you enter CREATE PROCEDURE etc.

• Oracle regular expressions - splits the string into words for

  Hello

  Nice day!

  My requirement is to split the string into words.

  This has nothing to do with REGEXP. Is SQL * more parser does not not a semicolon at the end of the line:

  SQL > select ' testto, mm\;

  Just break the chain:

• iOS 9.3 cannot open the links more on safari, mail, and other messengers

  My Safari on iOS 9.2.1 (update: and now 9.3) will not open most of the links more, i.e. by typing on a link on a page does nothing. Worse, other applications like Messages, Chrome are problems when they try to open URL links.

  The common question is breaks when you tapoterez links and even Mobile Safari press and hold (to get the app open a link in a new tab), the device will freeze and eventually crashes.

  Unfortunately, this is a common problem.

  Try turning off JavaScript under settings - Safari - Advanced.
