Using number datatype for date column

Hi
Is there a side effect for using "number" datatype for "date" column?
If so, what is the disadvantage?
Many thanks

Oracle provides date arithmetic and a number of functions for manipulating DATEs. None of them work with numbers.
For example,
SELECT    TRUNC (order_date, 'MONTH')     AS order_month
,       AVG (ship_date - order_date)     AS avg_delay
FROM       orders
GROUP BY TRUNC (order_date, 'MONTH')
;order_month involves a DATE function; it's pretty easy to find the month that conatins order_date.
avg_delay involves date arithmetic. It's extrememly easy to find how much the time passed between order_date and ship_date.
Depending on how you code dates as numbers, doing either one of the above may be just as easy, but doing the other will be very difficult. You'll waste a lot of effort converting the NUMBERs to real DATEs whenever you need to manipulate them.
Validation can be very difficult for NUMBERs, also.
Watch this forum. It's a rare day when there's not some question about how to get around a problem caused by storing dates in a NUMBER (or VARCHAR2) column. Don't add to that. Always use DATE columns for dates.

Using number field for date

Hi,
I have a number field that contain a date (YYYYMMDD). In my report I must show the date in the format DDMMYYY.
Please, help me.
TIA, Alex

Hi,
You can also change your query...
Instead of the column you are using, use
to_char(
to_date(
ltrim(
to_char(<date_field>)
, 'YYYYMMDD'
, 'DDMMYYYY'
Hope this helps

Looks like there is a 127-column limit on the number of report columns supported when using that wizard. Do you have more than that?

i exported the application from apex.oracle.com and imported it to our environment
import went fine, but when I ran the IR page I got
ORA-20001: get_dbms_sql_cursor error ORA-00904: : invalid identifier
evidently the problem is a lack of public execute on DBMS_LOB, which is used in the generated IR source.
while waiting for the DBA to grant privs on DBMS_LOB, changing the dbms_lob.getlength call to length() fixes the IR.
however, i am not getting the download link on the associated form page... changed templates, that's not the issue -- we'll see if that's a dbms_lob issue as well

APEX_UTIL.IR_FILTER with BETWEEN operator for date columns

Hi,
when I run my application I can set a BETWEEN-filter for date columns. I can't find a way how to use it with the APEX_UTIL.IR_FILTER function. Maybe I miss something?

Tobias,
If you think about it, a "Between" is nothing more than a single line way to say
WHERE :X >= :Y
AND :X <= :Z
So you should be able to apply two filters to the report using the LTE and GTE operators
Hope this helps

1) Use SNRO for defining a number range.

Which type of index is useful for date columns with time stamp

Hi all,
I am using date column in the where clause of an SQL Query. The values stored in the date column are includes timestamp. The query is very slow and there is no index on the date column.
Can any body suggest which index is better on date columns
Thanks

I am using date column in the where clause of an SQL Query.Dates a re hard queries to tune. This ...
WHERE start_date BETWEEN to_date('01-SEP-05') AND to_date('02-SEP-05')...probably requires a very different execution plan to this...
WHERE start_date BETWEEN to_date('01-JAN-01') AND to_date('02-SEP-05')Just bunging an index on the date column may speed up your specific query but break something else. So be careful.
Cheers, APC

Can I use custom datatype on a column?

Using sqlldr when source data column is 4000 chars

I'm trying to load some data using sqlldr.
The table looks like this:
col1 number(10) primary key
col2 varchar2(100)
col3 varchar2(4000)
col4 varchar2(10)
col5 varchar2(1)
... and some more columns ...
For current purposes, I only need to load columns col1 through col3. The other columns will be NULL.
The source text data looks like this (tab-delimited) ...
col1-text<<<TAB>>>col2-text<<<TAB>>>col3-text
more-col3-text
more-col3-text
more-col3-text
more-col3-text
more-col3-text
END-OF-RECORD
There's nothing special about the source data for col1 and col2.
But the data for col3 is (usually) much longer than 4000 chars, so I just need to truncate it to fit varchar2(4000), right?
The control file looks like this ...
LOAD DATA
INFILE 'load.dat' "str 'END-OF-RECORD'"
TRUNCATE
INTO TABLE my_table
FIELDS TERMINATED BY "\t"
OPTIONALLY ENCLOSED BY '"'
TRAILING NULLCOLS
col1 "trim(:col1)",
col2 "trim(:col2)",
col3 char(10000) "substr(:col3,1,4000)"
I made the column 3 specification char(10000) to allow sqlldr to read text longer than 4000 chars.
And the subsequent directive is meant to truncate it to 4000 chars (to fit in the table column).
But I get this error ...
Record 1: Rejected - Error on table COL3.
ORA-01461: can bind a LONG value only for insert into a LONG column
The only solution I found was ugly.
I changed the control file to this ...
col3 char(4000) "substr(:col3,1,4000)"
And then I hand-edited (truncated) the source data for column 3 to be shorter than 4000 chars.
Painful and tedious!
Is there a way around this difficulty?
Note: I cannot use a CLOB for col3. There's no option to change the app, so col3 must remain varchar2(4000).

You can load the data into a staging table with a clob column, then insert into your target table using substr, as demonstated below. I have truncated the data display to save space.

Attached document for data column in BPS Web application

Hi,
I have created layout for a BPS application, the layout has been configured to have the ability to allow the used to create the attached documentd for the data column. when the user open the layout through the planning profile, the icon for those documents is displayed and can be open by click those icons. After we generated the Web applicatios, those icons are gone and the user can not open them any more.
I notice that there is document subcomponent under BPS-WB, I added that subcomponent to my web layout, it still not work.Anybody know how to display the attached documents on the Web, Is this doable?

Hi Marc,
I did exactly what you mention in your responce e-mail, but it still not work coreectly.
following is my propperty configuration for layout and documents:
Planning layout (layout_lay01)
Only ready for output: True
Row/Cell Selection: Cell
Event on selection: true
Document on planning layout (Document1)
Layout: = layout_lay01
Only ready for output: false
When I launch the application through the Tcode BPS_WIF0
There is no document icon display for each data columns which can been in UPSPL. Instead there is a generic document input/display space under the lauout,however there is no any document display within the box, and I can not input anything within the document box. I changes some of the property for the layout and document, but it not work.
Did I forget some thing?
