  • To_Number fails because the number not valid

    I have a value which is unfortunately in a field of varchar (50) free form text and I'm updating a table which is a numeric field.  The data could be anything.  From my research, it sounds like its values as 18000, or $20,000, $23 000,00, $28 000,00 or or $35,000.0000.

    I tried the command To_Number and it failed.

    I made a function replace and stripped dollar signs and commas and the still empty spaces and as a last resort even stripped periods just to try to put incorrect data, perhaps thinking that the free text field has had two periods in it.

    I have an IS_NUMBER function and when I run the field through here, he said they are all numbers, but when I update it does not say that it is an invalid number.

    I have a long msft sql dba, but Oracle is all new to me.

  • SQL query to get the first four characters of an address

    Hi gurus,


    Can you please help me with the below quries on how to achieve this. Could be really helpful if you could provide a sample sql on your side.


    Req:

    I have a requriement where I should display the first four characters other than a space to address, for example: becomes R, DISH etc. F. in passing in a ROOM address a DISH 1 FLORIAN AVENUE would therefore "RAF1", while a CORNER, 23 STREET address would be "23CO".


    Words such as c/o, co, rear should be ignored, if any.

    Thanks in advance.


    Kind regards

    Peoples

    Hi John,.

    Here is an implementation of a pl/sql function that suggested a franc. It uses two lists, one with the words which are replaced with the first character and a second with words to ignore.

    create or replace function first_four (p_input in varchar2) return varchar2 is

    type t_words is table of the varchar2 (100);

    p_replace t_words: = t_words ('ROOM', 'FIELD', 'FLAT', 'FLT', 'BLOCK', 'UNIT', 'STUDIOS', 'CARAVAN', 'APARTMENT');

    p_ignore t_words: = t_words ("C/o ', 'CO', 'BACK TO'");

    v_input varchar2 (100);

    Start

    -Put the entry in a local-variable he

    v_input: = upper (p_input);

    -delete the words contained in the ignore list

    because me in 1.p_ignore.count

    loop

    v_input: = replace (v_input, p_ignore (i));

    end loop;

    -Replace the words by first character in the replacement list

    for r in 1.p_replace.count

  • Generation of a random not as - string for example

    Oracle Database 11 g Enterprise Edition Release 11.2.0.1.0 - 64 bit Production

    Hello

    I want to generate randomly, a string of tank that is not like a tank.

    Select str of (select DBMS_RANDOM. String('U',1) double str) where str! = « A » ;

    a few times I get NULL. How can I get a tank all the time? I want to create a function using this logic. can someone help me reach this goal?

    Thank you

    I think that's what you want:

  • Timestamp format

    How can I convert under query timestamp? Is the difficult part a 't' in the string.
    SELECT '20080101T07:32:39.785', to_timestamp(SUBSTR('20080101T07:32:39.785',0,17),'YYYY-MM-DD HH24:MI:SS,FF') FROM DUAL;

    Maybe not the best, but here's a way... first step is make your format string to match your string input and using the right index for SUBSTR. Second step is to detach the T via REPLACE()

    SELECT '20080101T07:32:39.785',
to_timestamp(SUBSTR(replace('20080101T07:32:39.785','T',''),1,16),'YYYYMMDDHH24:MI:SS,FF')
FROM DUAL;

  • Count of weekdays only in SQL

    Dear all,

    Yesterday, I posted about general SQL ignoring the weekend of the County of the query, but all solutions failed. I'm now paste here real SQL. This SQL returns delay_days which also includes weekends. I want it must ignore weekend DAYS and counting only the DAYS WORKING (WORKING days). For example, if necessary, shipment is sent on Tuesday and if it reaches the Monday instead of 7 days, it should return 5 days as delay_days while ignoring the two weekend days.

    Your help on this would be much appreciated.

    GQ says:

    ORA-01846 : not a valid day of the week

    As I indicated in my original answer my solution is dependent on NLS. It seems that your NLS_DATE_LANGUAGE is not English, that's why it does not recognize day names:

    SQL> select next_day(sysdate,'SUNDAY') from dual
  2  /

NEXT_DAY(

    Relevant day you either appoints or make independent NLS changing SATURDAY to TO_CHAR (TRUNC (sysdate, 'IW') - 2, "fmDAY") and SUNDAY with TO_CHAR (TRUNC (sysdate, 'IW') - 1, "fmDAY"):

1.86 GHz, 3.25 GM or RAM
    I did an import complete database after you create storage space required database 10g on Linux to Windows.
    On the database 10g for Windows, I put maximum SGA size to 1300 MB and the size of the Total SGA to 1000 MB. I put the overall target of PGA at 500 MB.

    This Windows box will be used by more than 2 developers for a change to our application that isn't backward compatible (with respect to the database) with earlier versions of the application that uses the database. Asked me to create this so we could develop this branch without affecting the rest of the development team working on further improvements on the Linux machine.

    I then ran a few packages that update data to a set of tables. It passes through a code that has a lot of data, so I have discovered all of the problems.

    At a specific time in the execution of these packages, I get the following error:
    ORA-07445: exception encountered: core dump [ACCESS_VIOLATION] [_qkkIsOJKey+299] [PC:0x1E58F73] [ADDR:0x80] [UNABLE_TO_READ] []
    I have read the trace file and isolated to a single, somewhat complex query. I tore the request into smaller requests, trying to isolate what was causing the problem. Whenever the memory image occurred, I could get simply by closing the connection and open a new connection. In my tests, I found the specific query that triggers the exception and a less effective version of this query that does not cause the exception. Please note that this exception has never happened on the Linux machine (or if it is produced on the basis of data of production or beta), and the code has been implemented for nearly 2 years.

    The code that causes the problem:
    SELECT UNIQUE 
       oc.ogc_case_id AS oc_ogc_case_id, 
       ogc.ogc_number AS ogc_number
  FROM (SELECT SUBSTR (REPLACE (afd.field_text, '-', '' ), 1, 6 )    AS ogc_number
          FROM ewoc_hw_snap.activity_field_data afd 
         WHERE afd.afdcd_activity_field_data_key = (SELECT afdc.activity_field_data_key 
                                                      FROM ewoc_hw_snap.activity_field_data_codes afdc 
                                                     WHERE afdc.name = 'Case Number' 
                                                   ) 
       ) ogc 
  LEFT OUTER JOIN lct_snap.ogc_cases oc 
        ON oc.ogc_number  = ogc.ogc_number
    The code that returns the same data, only slower and does not raise the exception:
    SELECT UNIQUE 
       (SELECT oc.ogc_case_id FROM lct_snap.ogc_cases oc WHERE oc.ogc_number = ogc.ogc_number ) AS oc_ogc_case_id,
       ogc.ogc_number AS ogc_number
  FROM (SELECT SUBSTR (REPLACE (afd.field_text, '-', '' ), 1, 6 )    AS ogc_number
          FROM ewoc_hw_snap.activity_field_data afd 
         WHERE afd.afdcd_activity_field_data_key = (SELECT afdc.activity_field_data_key 
                                                      FROM ewoc_hw_snap.activity_field_data_codes afdc 
                                                     WHERE afdc.name = 'Case Number' 
                                                   ) 
       ) ogc
    I ran both queries with SQL Developer 3.0.04 version. Developer SQL gives the error message: no more data to read from socket

    Any ideas?

    The above query is simple I could pare to raise and then solve the problem. The patch package is not as simple as the second query above since there is more than one column of data that I must return from the lct_snap.ogc_cases table. In any case, I wouldn't have to give up using the LEFT OUTER JOIN. There must be something wrong with the database of Windows. I didn't patch the Windows database without checking first on this forum to see if anyone had less intensive alternatives.

    I searched and found so many messages with the ORA-07445: exception encountered: core dump [ACCESS_VIOLATION] error, that I realize this is a somewhat generic error message.
