How to build a list or a table with fixed values?

Is it possible to create a list or a table with fixed values, but with a variable length?

for example:

var columns = "name, age, function;

var insertParams = generateList ( listLen (columns), ',','.) » ); *

fact: insertParams = ',?,??


* (this function does not exist. This is just to illustrate what I need)

I know that this feature is easily created by creating a loop, but I was wondering if it was possible with a single line of code.

Thank you

If he can generate a table in the same way, which would be as well.

Our messages have clashed. But I think that repeatString() would do the trick. You could cut the rear comma with left() or convert it to a table. By default, ListToArray() will silently ignore the trailing comma.

  • 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.

  • Fill the table with random values

  • Table with fixed header and the left column

    I created a table in my application with the fixed left column (left most column is fixed and remaining columns are scrolling from left to right). is it possible to create a table with fixed position and fixed left column?

    Suppose there are 50 rows and 10 columns in my paintings, and only 3 columns and 15 rows are visiable on the screen

    (1) when the user scroll left to right left only most of the columns must be fixed. Remaining cap of the table and column scroll left to right and vice versa. also

    (2) when user scroll high high bottems single topic most must be fixed and remaining all lines (with to the left most column) should be scrollable.

    I am able to put in place a point at the top, but not both. Please suggest

    "If I repopulate the value in the cell when user scrolling, shell, I get scrolling effect correctly as it only shows half cell when the user highlight half of the cell."

    Approach using TablelayoutManager display single cells and scrolling would be cell at a time.  And Yes, you will need to override navigationMovement and n of methods appropriate TouchEvent your TableLayoutManager so that he knows when to fill the cells.

    Another alternative is to have four managers, we don't the the upper left corner (the dead angle), one to make the top row (column headings), one to make the left column (row headings), and the other to do the rest (data).  Place all these in a delicate header and line manager.  Only allow the user to scroll the data part.  Have the difficult Manager to listen the scroll events.  Then have the wily Manager add and remove the dummy column and header line managers as appropriate.  Note that these topic fields would not good passes, they would be either there or they would not be displayed. That would give you your 1/2 a scroll of the cell.  And you wouldn't have to substitute anything to detect movement, you would have left the listener do scrolling for you.

    You're up-to-date data are probably not ObservableValues as properties, so the TableView cannot update dynamically as modification of data items.

  • How to find the size of a table with CLOB

    Hello

    I have a table with CLOB as follows:

    SQL > desc INFO_MESSAGES

    Name                                      Null?    Type

    ----------------------------------------- -------- ----------------------------

    CLNT_OID NOT NULL VARCHAR2 (16)

    USR_OID NOT NULL VARCHAR2 (16)

    LAST_client_msg_ID VARCHAR2 (36)

    LAST_client_msg_DATE DATE

    LAST_client_msg CLOB

    LAST_USR_MSG_BOD_ID VARCHAR2 (36)

    DATE OF LAST_USR_MSG_DATE

    CLOB LAST_USR_MSG

    Now I just want to find out what is the size/area total absorbed by the table (including the CLOB columns), so how can I find? I think that the usual command does not - the

    Select format from dba_segments where nom_segment = "INFO_MESSAGES" is only showing 7 MB, while I think that the table has several GB of space due to the CLOB.

    Also to add one more detail: when dba_segments seeking, I see a result like this:

    Select * of dba_segments order by bytes DESC;

    MIGRTN SYS_LOB0000111131C00008$ $ LOBSEGMENT SAMS DATA1 20690 6 1963 14528000 119013376000 <-the top row

    MIGRTN this is the schema where this INFO_MESSAGES table is present.

    Thanks,

    OrauserN

    you will need to add the segment_size of the LOB segments to the segment_size of the table. The connection between the two pieces of information you find in USER_LOBS (or the corresponding ALL_, DBA_ objects).

    I have a question. I need a selection list containing the time with 15 minute intervals from 08:00 until 16:00.
    example 08:00
    08:15
    08:30
    08:45
    09:00
    09:15
    and so on until 16:00
    Or values stored in a column of varchar type.
    Can someone help me with this one please?

    Best regards
    Caroline

    You can generate the entries in a dynamic way, as:

    select  to_char(trunc(sysdate)+8/24+(level-1)*1/96,'HH24:MI') period
    from    dual
    connect by level <= 33 
    

    or if you want/need to use your stored values:

    select display_column, return_value from table where
     display_column in (
                   select  to_char(trunc(sysdate)+8/24+(level-1)*1/96,'HH24:MI') period

  • REGEXP_SUBSTR for the list delimited by commas with null values

    Hello

    I have a column that stores a list of values comma-delimited. Some of these values in the list may be null. I'm having some trouble trying to extract the values using the REGEXP_SUBSTR function when null values are present. Here are two things I've tried:
    SELECT
       REGEXP_SUBSTR (val, '[^,]*', 1, 1) pos1
      ,REGEXP_SUBSTR (val, '[^,]*', 1, 2) pos2
      ,REGEXP_SUBSTR (val, '[^,]*', 1, 3) pos3
      ,REGEXP_SUBSTR (val, '[^,]*', 1, 4) pos4
      ,REGEXP_SUBSTR (val, '[^,]*', 1, 5) pos5
    FROM (SELECT 'AAA,BBB,,DDD,,FFF' val FROM dual);
    
    POS P POS P P
    --- - --- - -
    AAA   BBB
    SELECT
       REGEXP_SUBSTR (val, '[^,]+', 1, 1) pos1
      ,REGEXP_SUBSTR (val, '[^,]+', 1, 2) pos2
      ,REGEXP_SUBSTR (val, '[^,]+', 1, 3) pos3
      ,REGEXP_SUBSTR (val, '[^,]+', 1, 4) pos4
      ,REGEXP_SUBSTR (val, '[^,]+', 1, 5) pos5
    FROM (SELECT 'AAA,BBB,,DDD,,FFF' val FROM dual);
    
    POS POS POS POS P
    --- --- --- --- -
    AAA BBB DDD FFF
    As you can see that neither calls work correctly. Anyone know how to change the regular expression pattern to handle null values? I tried various other models but could not get anyone to work in all cases.

    Thank you

    Hi, Martin,.

    That's what you want:

    SELECT
       RTRIM (REGEXP_SUBSTR (val, '[^,]*,', 1, 1), ',') pos1
      ,RTRIM (REGEXP_SUBSTR (val, '[^,]*,', 1, 2), ',') pos2
      ,RTRIM (REGEXP_SUBSTR (val, '[^,]*,', 1, 3), ',') pos3
      ,RTRIM (REGEXP_SUBSTR (val, '[^,]*,', 1, 4), ',') pos4
      ,RTRIM (REGEXP_SUBSTR (val || ','
                          , '[^,]*,', 1, 5), ',') pos5
    FROM (SELECT 'AAA,BBB,,DDD,,FFF' val FROM dual);
    

    The query above works in Oracle 10 or 11, but in Oracle 11, you can also do it with only REGEXP_SUBSTR, without using RTRIM:

    SELECT
       REGEXP_SUBSTR (val, '([^,]*),|$', 1, 1, NULL, 1) pos1
      ,REGEXP_SUBSTR (val, '([^,]*),|$', 1, 2, NULL, 1) pos2
      ,REGEXP_SUBSTR (val, '([^,]*),|$', 1, 3, NULL, 1) pos3
      ,REGEXP_SUBSTR (val, '([^,]*),|$', 1, 4, NULL, 1) pos4
      ,REGEXP_SUBSTR (val, '([^,]*),|$', 1, 5, NULL, 1) pos5
    FROM (SELECT 'AAA,BBB,,DDD,,FFF' val FROM dual);
    

    The problem with your first request was that he was looking for sub channels of 0 or more non-virgules. There was as a substring. consisting of 3 characters starting at position 1, he returned "AAA", as expected. Then there was an another substring, the 0 characters, starting at position 4, so it returned NULL. Then, there was a substring of 3 characters starting at position 5, so he returned 'BBB '.

    The problem with your 2nd request was that he was looking for 1 or more non-virgules. 'DDD' is the 3rd this substring.

  • Fill an empty table with predefined values

    Thank you

    Aj05,

    The best practice for this would be to use method call activities in the workflow as suggested change.

    Suggestion of Vinod was the only way to do it in 10g, but I wouldn't recommend it to 11g, as the implementation of the action is hidden in the definition of the page and you must understand the State of refresh and refresh and to ensure that the action does not more often than you. Task flow approach shows explicitly when the method is called

  • Fill a table with date values with a fixed increment

    Hello

    I want to fill a table with a date column with the increment of a fixed value date values. The start date is selectable, the increment is selectable and the number of records is adjustable as well.
    For example
    start date is 1905-Jan-02, 15:00 (DD-MON-YYYY, HH24:MI:SS)
    increment is 1 hour and 5 minutes
    None. records is 10
    then the dates in the table must be
    REC 1 1905 - Jan - 02, 15:00
    REC 2 1905 - Jan - 02, 16:05
    REC 3 1905 - Jan - 02, 17:10
    ....
    REC 9 1905 - Jan - 02, 23:40
    REC 10 1905 - Jan - 03, 00:45:00

    We are working on 11 GR 2, the number of records can be between a few hundred and a few million and they must be ordered with Crescent of time (maybe to have a whole id).
    Any ideas how to fill this table (simple and fast?) using sql / plsql are welcome.
