hi to all,
why we can not give datatype size in procedure parameters any one help me urgent,

Hi,
Welcome to the forum!

Someone started another thread on the same question just a little earlier: {message:id=10989165}. See that thread for more.
any one help me urgent,If you need help urgently, this is not the place to ask for it. People answer questions when they want to, not necesarily when you command them to. Using terms like "urgent" or "ASAP" is not only rude, it's self-defeating. That is, nobody will refuse to give you an answer because you did not say it was "urgent", but some people may not answer because you did say it.

Data type size for the view column

I am creating a view from base table using substr() for some fields. The data type size of the column in the view becomes twice the size of the corresponding column in the base table. Example
SQL> create table temp_sat(name varchar2(20));
Table created.
SQL> create view temp_view as select substr(name,1,10) name from temp_sat;
View created.
SQL> desc temp_view
Name Null? Type

Please confirm is the maximum Text Data Type Size within MDS 4000 characters

Hi,
Please confirm is the maximum Text Data Type Size within MDS 4000 characters?
If you could give me a link referencing my answer to the above question that would be even better.
Kind Regards,
Kieran.

However I am extending a system which stores dynamic SQL within an MDM column to facilitate a generic extract and load process. I am sure you are already aware in this type of scenario the business rules behind a piece of dynamic SQL defining a generic
extract process could easily exceed 4000 characters.

Data type size does not match values returned

I've tried searching but couldn't find what I was looking for, sorry if this has been answered or is a duplicate.
I am using the (Java) method below to get the column definitions of a table. I am doing this through an ODBC connection (using Oracle ODBC driver) and I have NO CHOICE in the matter.
The problem I am having is that one particular column has a column size is smaller than the size of the data it purportedly holds (ie attendance_code = varchar size 3 but data value is "Absent". I suspect the data is actually a look up to situation, where my attendance_code column has a value of 'ABS' and Oracle goes and fetchs the "Absent" value.
My issue is that the meta data returned from ODBC is the actual column definition (ie varchar(3) and not varchar2(10) for example).
How do I resolve this? I do not have access to all_columns table etc. I have to do it using ODBC metadata only.
TIA.

John, thanks for your reply.
As far as I know I'm not doing anything inaccurately/incorrectly.
The select I am using is SELECT * FROM <tableName>.
The resultset metadata has a size of 3 for the column in question, and querying the schema also yields 3 for that column.
I've tried recreating the situation using the Oracle XE DB, but as I am not familiar with Oracle, I do not know how to recreate this scenario (which would then lead me to test other options with ODBC).

Which Data-Types can be used as Widget Parameters?

Hi,
I have been playing about with widgets (specifically widget parameters) for a while now.
I've got to wondering, exactly which data-types can Captivate turn into widget parameters?
So far I know that you can use:
Numbers,
Strings,
Arrays,
Objects
and Booleans,
as parameters.
Which ones am I missing?
I know some don't work, because I tried storing a MovieClip as a parameter and that didn't work.

Hi Eccles,
You can set all basic data types supported in flash viz.,
1)Numbers
2)Strings
3)Arrays
4)Objects
Since in Action script , an Object can be anything (array , array of objects , array of objects which by themselves are array of objects and so on ) , you can virtualy send anything as widget params
But there are two caveats to this
1)Object References
-Object References do not have any meaning once the swf is closed.But the widget params have to be stored across sessions.So If you send a reference as part of widget params it is not going to work.
This is why sending a Movie Clip (which is actually a reference to an Object ) does not work
If you want to send such things you will have to 'serialize' the object.
2)Size of the Object that you send
The size of the object that you send can have an impact on performance.And since any object that you send has to be converted into XML , objects like bitmaps can turn out to be huge and difficult to handle.
This brings us down to this - you can send any object across as widget param as long as it is small and serialized.

column.setOrdinalPosition(rs.getInt("ORDINAL_POSITION"));
columns.add(column);
} catch (Exception e) {
Log.getLogger().error("Could not capture table schema");
closeResultSet(rs);
return columns;
}

I can't say I've ever seen a case where a column held more data than it was declared as, and would have to file that under "see it to believe it" category.
Even if that somehow were the case, I'd expect the ODBC driver to return what the column is defined as anyway, not the data. The data changes with every row, but I'd expect the table metadata to be consistent, and refer to the table definition.
For grins though, can you provide system.out.println output of the metadata, and also a "describe xxxx" from sqlplus if you can, where xxx is the table name?
ie,
while (rs.next()) {
System.out.println("column name is " + rs.getString("COLUMN_NAME"));
System.out.println("data type is " + rs.getInt("DATA_TYPE"));
..etc..

Data type of preprend array size in Flatten To String block

Hi
The data type of the preprend array size in Flatten To String block is given as I32. Is it somehow possible to reduce the data type to I8, since the width and height of my array won't exceed 255 ?. I also need to do the same in Unflatten To String as well.
Best regards
Oesen

The short answer is no. This is because the index is an I32. NI likes to keep integers as an I32 whenever possible for reasons like this.
Since you are dealing with a 2D array (width and height), it will actually use 2 I32s before the actual data.
As Ravens stated, you could put in your own array sizes before the array in the string. But it is worth saving 6 bytes? Not likely.

Data type with large size in a table and updating it

Hi guys,
i am working on a requirement in which i need to create 4 tables. Here, 2 tables will be updated by the user and a program will update this content to the other 2 table.
2 days before i posted a query on this, Previously i stucked on a part where, table need to entries with size char 400 and char 9000. As from the reply, i changed it to STRING with which table was sucessfully created and i was able to update data through a report program.
Now we ned to provide an sm30 option to users, so they can insert new contents and update the status of old contents. But when i tried this table maintanance generator, i got an error that table contains string, so maintanance generator cannot be done ! i changed the data type to rawstring also. Now maintanance generator got saved, but when i open the table in sm30, i am getting dump saying tht table is using string/char etc.
can anyone tell me what data type to use in this scenario with which we can enter data through sm30 ?

Hi Kithu,
you can use STRING (or XSTRING) fields. Then there is no limit on the field size. As long as it is not (fully) filled with data, no space is wasted.
The disadvantage is that STRING type data are treated as 'deep' structures. That leads to some trouble in the definition of interfaces. Give it a try!

Best data type to represent a file size

Hi All!
I have to create a table which holds details abou the files which process on a system and maintain the file name process, size of the file in byts, full path location the file is stores etc.
My question is what would be the best data type for a file size, currently the system proceess 4 GB files but I do not know whether this will expand so I need a data type which will be compatible for any size ther will be no decimal points involved in this.
I hope my question is clear.
Thank you in advance.

XML operation resulted an XML data type exceeding 2GB in size. Operation aborted.

I have table with one million rows, when i am using xml path ('Root'), it giving me an error
"XML operation resulted an XML data type exceeding 2GB in size. Operation aborted."
This is a limitation of sqlserver. I have to xml path because i have to create nodes and attributes. In more complex case i will be joining multiple tables to get id and other attributes so combining multiple xmls in not an option here.
any workaround....thanks in advance

Here an example of your query that retrieve record in batch of 2 records. In real code, you should save the last id retrieved and call the query in a loop.
DECLARE @BATCHSIZE AS integer
SET @BATCHSIZE = 2
DECLARE @LASTID As Integer
SET @LASTID = 0
select top(@BATCHSIZE) id as "@id"
,name as "@name"
select id as "@id"
,name as "@name"
select *
from @products p
where p.customer_id = cs.id
group by id,customer_id,name
for xml path ('product'),Root('products'),type
from @customer cs
where cs.client_id = c.id
group by id,client_id,name
for xml path ('customer'),Root('customers'),type
from @client c
where c.id > @LASTID
order by c.id
for xml path ('clients'),Root ('Main')

What is the size of number data type.

what is the size of number data type (in term of memory storage ;byte ).
Does it make different in size if mention number(38,0)?
Thanks all in advance...:)
Edited by: user10648897 on Jan 7, 2009 6:43 AM

NUMBER (p,s)
Number having precision p and scale s. The precision p can range from 1 to 38. The scale s can range from -84 to 127.number(38,0) = number(38)

What is the size of a string data type

Hello,
What is the size of a string data type. Also what is the maximum size upto which a text file can grow?
Thanks in advance
cooldude

Hi cooldude,
the size of a string is given back by the function "String size". Strings are dynamically managed in LabView.
The max filesize is limited by the used filesystem. FAT-based systems are limited to 4GB (or was it 2GB?), other filesystems may allow more...

Pl/sql Procedure is Not Creating With the CLOB data Type

Hi,
I am Using Oracle 10g Express Edition Release2.... My Doubt is While creating a table With CLOB Data Type the table is created successfully,but while Creating a Procedure With the CLOB Data type i am getting an Error Message
2667/5 PL/SQL: Statement ignored
2667/24 PLS-00382: expression is of wrong type
then i tried With the Varchar2(30000) the Procedure is Created Successfully note i have not changed any thing in my code except the data type.
I am Just Confused ......Why the Procedure is not Created with CLOB Data type?
Please advice ...
Thank U
SHAN

hi,
Thanks for reply....Another Example
CREATE TABLE USER_MAS (USER_ID VARCHAR2 (20 Byte),MAIL_ID VARCHAR2 (255 Byte));
set serveroutput on
declare
atable varchar2(64) := 'USER_MAS';
acolumn varchar2(64) := 'MAIL_ID';
avalue varchar2(64) := 'NEWYORK' ;
dyn_sql clob;
begin
dyn_sql := 'update '||atable||' set '||acolumn||' = '''||avalue|| '''' ;
dbms_output.put_line(dyn_sql);
execute immediate dyn_sql;
end;
commit ;

PL/SQL: Statement ignored
When i Changed the Data type to varchar2(64)
update USER_MAS set MAIL_ID = 'NEWYORK'
PL/SQL procedure successfully completed.
Commit complete.
I like to Know the Reason Why the Procedure is Not Created in Oracle 10g XE DB
Note :the Same Script i used in 11g DB the Procedure is Created Successfully....
Why you need use CLOB or VARCHAR2 in your temp_num variable as you sending parameters as number?
In the Procedure we are create some run time queries while executing the procedure. There are around 10 run time queries created.
The size of each query is more than 4000 characters . We then add all the queries using union all after each query to the clob variable as the normal varchar will not support.
Please Advice

We have already checked in everywhere in the system, got oracle support as well without success. The control files are in the place and checked with strings, they are correct.
Can somebody give a clue please?
Maybe somebody had similar issue here....
Thanks in advance.

Did the touch to update the date, but no joy either....
These are further logs, so maybe can give a clue:
