  SELECT TO_DATE ((substr (record_date, 1, 10), ' DD/MM/YYYY') of?)

  TO_DATE (substr (record_date, 1, 12), "HH24 MON-DD-YY")

• convert the varchar2 data type to the data number type

  col1 varchar2 (50)
  col2 varchar2 (500);

  I need to create a table with the same columns with data like number types (19)
  
  can someone help me
  
  Thank you

  You have changed your original post, so now I see that you get the invalid number.

  This is why you should always avoid the varchar columns to store numbers or dates...

  Since your table source contains a nonnumeric value, you can write a pl/sql to convert data and see what records are false:

  SQL> insert into a (col1,col2) values ('xxxx','2345');
  
  1 row created.
  
  SQL> select * from a;
  
  COL1     COL2
  -------- --------
  1234     2345
  xxxx     2345
  
  2 rows selected.
  
  SQL> create table b (col1 number(19), col2 number(19));
  
  Table created.
  
  SQL> set serverout on
  
  SQL> declare
    2  cursor c is
    3  select * from a;
    4  begin
    5    for r in c loop
    6     begin
    7       insert into b values (to_number(r.col1), to_number(r.col2));
    8     exception
    9       when invalid_number then
   10        dbms_output.put_line('Row rejected: col1='||r.col1||' col2='||r.col2);
   11     end;
   12    end loop;
   13  end;
   14  /
  Row rejected: col1=xxxx col2=2345
  
  PL/SQL procedure successfully completed.
  
  SQL> select * from b;

• Convert a varchar2 data type Date

  Hi guys,.
  
  Can someone help me convert a Varchar2 data type in the data type Date?
  
  I have a query and my column is a varchar2 data type.
  I want to just that convert the Varchar2 in a DATE, because I met
  problem in my query. I want to do the day1 day10 transaction.
  
  Ex:
  Day 1 = January 1, 2010
  Day10 = January 10, 2010
  
  table.record_date varchar2 (12)
  
  SELECT column1, Column2
  table
  where record_date between? and?
  
  How can I set the record_date between day1 and day10 since record_date is of type varchar?
  
  Thank you.
  
  Laetitia

  Lala,

  If the data in the database are in the format MM-DD-RR , then you must use the same format when you convert back to this day.

  So change the query to

  SELECT COLUMN1, COLUMN2 FROM TABLE WHERE TO_DATE(RECORD_DATE, 'MM-DD-RR') BETWEEN TO_DATE('01-JAN-2010') AND TO_DATE('10-JAN-2010')
  

  Kind regards

• Bad high and low value with the varchar2 data type

  Hello
  
  It is an application on e - biz on database 9205, with inventory module.
  
  In one of the mtl_txn_request_headers of the table, the data for the number of application type is varchar2 (30). When I checked the low_value & high_value in dab_tab_columns, I see that the low_value is 100001 (6 digits) and high_value is 99999 (5 digits).
  
  I used the utl_raw.cast_to_varchar2 (low_value) to convert the value.
  
  In our case, we save a large part of the value in incremental number and some of our query will be in the predicate of the range (between).
  
  How should I handle this kind of situation and which option do I?
  
  Appreciate any help. Thank you.

  Accepted this looks like a classic bad-data type problem, but as this picture seems be part of Oracle E-Business Suite the OP should probably talk first Oracle.

• Employee_number hr.per_all_people_f varchar2 data type

  Hello Oracle gurus, could someone tell me why the number of employee in the table Per_All_People_F column is varchar2 instead of the data type data type Number.
  
  Thanks in advance, Naveen Gagadam

  Hi Naveen

  The employee number may be whatever it is based on the requirement, for example, you can have employee number which begins with the a. The data type of this field is Varchar2 instead of the number so you can customize employee number using the quick forumla.

• Import XML and bad data type

  Hi all!

  I have a form, I want to import xml data.

  In the xml data file: when I put a string in a numeric field (error) and the i value import data in my form:

  Acrobat don't tell me there is an error in 'format', but rather the value 0 (zero) value is put is the field.

  Is there a way (early event) to detect a data format error in the xml file?

  Thank you

  Not that I know of... .He is trying to bind the to imbound field in the form field and if it can you see your data... otherwise it will not appear.

  It is assumed that the incoming data was validated against the schema before importation is made so avoid data type mismatches.

• create new tab with the name of the pass and the data type of the tab & ranks on the b tab

  If you see C, there new column names, derived from the Tag_label of the table A column names and the lines are filled with the values from table B corresponding to the tag_column_name of the column of table A
  
  Is it possible to do so. This is very important because it is the main part of my project and I'm stuck on this.

• date and timestamp data type lengths

  Hello
  
  Documentation, says the following:
  
  : Date parameter valid [...]. The size is fixed to 7 bytes. This data type contains the datetime fields YEAR, MONTH, DAY, HOUR, MINUTE, and SECOND. There can be no fractions of a second or a zone.
  
  TIMESTAMP [(fractional_seconds_precision)]
  Year, [...] setting. The size is 7 or 11 bytes, depending on the precision. This data type contains the datetime fields YEAR, MONTH, DAY, HOUR, MINUTE, and SECOND. It contains fractions of a second, but does not have a time zone.
  
  However, if I create a table as follows:
  
  create table t9 (timestamp (3) c1, c2 date);
  
  and do:
  
  insert into values t9 (systimestamp, sysdate);
  commit;
  
  Select length (c1), (c2) length, lengthb (c1), (c2) lengthb of t9.
  
  I get
