How to find the Data Type of a column

Dear All,
How to find the Data Type of a Column dynamically in oracle Form.
Thanks and Regards,
Fazil
Edited by: user11334489 on Aug 25, 2012 9:06 PM

hi,
you can use get_item_property built-in
eg:
declare
l_item VARCHAR2(10);
begin
l_item := Get_Item_Property('item_name',DATATYPE);
end;

Determining the data type of the list item

Hi experts,
i have a dpop down list item in my form and from it i want
to select some of the columns of emp table like mobile_number or address
and send the selected field,along with name and empno to reports.
But when i am trying to determine the data type of the selected
item i am faceing some difficulties.
i am trying this
param := emp.:emp.LIST10%type;
can you please help me.
Regards
rajat

param := emp.:emp.LIST10%type;I'm not quit sure what you are trying to achieve with this.
If have build a poplist as a block-item you know the datatype of that item. When you know want to create a local variable to take the value from that list, either define it just with the datatype taken from the item, or take it dynamically from the column from the database the item is based on, so
DECLARE
-- explicit
vcParam VARCHAR2(50);
-- takeing datatype from db-column
vcParam TABLENAME.COLUMNNAME%TYPE;
BEGIN
-- Assignment
vcParam:=:EMP.LIST10;
END;

I need help in "HOW TO EXTEND THE DATA TYPE SYSTEM"......

Hi All,
I need to add new data type like SDO_GEOMETRY in spatial Oracle.
I don't mean the User-Defined Datatype but new datatype embed in the database.
I read the Data Cartridge Developer's Guide but it has info how to use more efficiently UDT through indexes.
Anybody used the “Type System” under Databases and Extensibility Services?
It might be written in C++ or Java but I do not know how.
Any hints and help will be appreciated.
Thanks,

> In Figure 1-1 Oracle Services, there is a "Type System" as Oracle Services.
The "Type System" is merely a compartmentalising the data type handling and implementation code/modules in Oracle.
This covers all types. Oracle native types, user defined types (UDTs), etc.
Saying that you want to create a new type in the "Type System" is basically saying you want to use the CREATE TYPE SQL command in Oracle.
> So, I want new_type1 and new_type2 behave like other built-in types, just the way
SDO_GEOMETRY works in Oracle Spatial Cartridge.
Not familiar with the SDO_GEOMETRY. Why do you mention this type specifically? What do you want to do similar?
> I have already done it with user-defined types. Now I need to do this way so that I can
compare and contrast in terms of speed, space...etc for part of my research.
Hmm.. I'm not sure what you are trying to compare ito of a UDT and Data Cartridge extensions. It is not one or the other. What research is this if I may ask?
Simplistically you extend the Type System with a new UDT/ADT. And there you have a new type data can be used in the SQL Engine and the PL/SQL engine. The OCI (Oracle Call Interface) supports such types via the OCI object API calls - which means this new type can also be used from Oracle clients written in Delphi, C++, Java, etc.
That new type can be a complex type. This type may need specific management code (memory management, context management, internationalisation, etc). To support this you can extend the UDT/ADT further by developing Cartridge Basic Service interfaces for the type - designing and writing management code to, for example, support specific internationalisation requirements when dealing with multibyte character sets.
You can also extend the UDT/ADT to be custom managed ito indexing, determining query optimisation, computing costs of custom methods/functions/operators on this custom data type. These extensions are done by developing Data Cartridge interfaces for the type.
Thus I cannot see what you are trying to compare. It is not one layer/interface versus another. These layers exist for all Oracle types (in the Type System). Oracle not only allows you to add to the top layer by adding/defining a new data type. It also allows you to customise (if needed) the layers below it.

How to change the data type of an item in administrator

Hi,
A summary folder was created. One of the item in the summary folder is a sum. That sum item was created in the business area (based on another item). I can't refresh that summary folder because it gives me an oracle error (Ora-12008 and Ora-01401 the value is too large for the column). The column that this item is based on is of data type Number(13). How can I fix this problem without changing the column's data type of the original table? I already tried altering the data type in the EUL table via TOAD.
Thanks!

You really don't need to sum the item before hand if you are going to create a summary!

How to change the data type in the table ESLL for the field USERF2_NUM ?

Hello Friends,
I have a requirement in which one of the change is to convert the data type of the field 'USERF2_NUM' in the table 'ESLL' from 'QUAN' to 'CHAR'.
How do i do it if i have an access to change it..........i think i should also check the impact of the change if done.
Kindly tell me as my requirement starts with this small change.
Regards,
Rajesh Kumar

Thanks for the reply Sowmya.
I would like to know 2 things.
1. Is it ok to change the data type of the field 'USERF2_NUM ' which is in the table ESLL. from quan to char.
2. The table ESLL already has entries. if we change the data type from QUAN to CHAR what is the effect on the existing entries of the table .
Kindly reply me back.

How to get the Data type of the Internal Table.

How can i get the data types used to create an internal table
TYPES : BEGIN OF t_makt,
          matnr    TYPE    matnr,
          maktx    TYPE    maktx,
        END OF t_makt.
Like this some function will give me which data types i have used for the internal table at run time.

Use the FM ..
data : int_fcat type SLIS_T_FIELDCAT_ALV.
REUSE_ALV_FIELDCATALOG_MERGE ..
CALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE'
       EXPORTING
            I_PROGRAM_NAME         = sy-repid
            I_INTERNAL_TABNAME     = 'IMAT'   <-- this is your internal table
             I_INCLNAME             = sy-repid
       CHANGING
            CT_FIELDCAT            = int_fcat <--- this contains all the fields along with their characteristics ...
       EXCEPTIONS
            INCONSISTENT_INTERFACE = 1
            PROGRAM_ERROR          = 2
            OTHERS                 = 3.

How to Find the Data Type of the Field In a Database Table

Hi Experts,
I'm currently working on a program which needs to find out the data type of the given field in a database table. In addition to accessing DD03L directly, is there any other workaround such as function module to help me achieve this? It would be helpful if a demo example could be provided.
Thanks a lot.

Hi,
Use this..
DESCRIBE FIELD dobj TYPE typ.
write typ.

How to retrieve the data type of a column of a table?

Hi,
I want to retrieve the data type of a column of a table. At the moment I am querying "OCI_ATTR_DATA_TYPE" attribute but it is returning SQLT_CHR for both varchar2 and nvarchar2 data type columns. I need to distinguish between these two data types columns separately. Is there any API through which I could get the exact data type of a column i.e. "nvarchar2"?
Thanks in advance.
Hashim

Hi,
This is the Oracle C++ Call Interface (OCCI) forum - I'm not sure if you are using OCCI or OCI (Oracle Call Interface - the C interface) since you reference "OCI_ATTR_DATA_TYPE" which is more of an OCI focus than OCCI.
In any case, you might take a look at "OCI_ATTR_CHARSET_FORM" which takes the following values:
#define SQLCS_IMPLICIT 1 /* for CHAR, VARCHAR2, CLOB w/o a specified set */
#define SQLCS_NCHAR 2 /* for NCHAR, NCHAR VARYING, NCLOB */So, if you have a datatype of SQLT_CHR and OCI_ATTR_CHARSET_FORM is SQLCS_IMPLICIT then you have a varchar2 if it is SQLCS_NCHAR then you have an nvarchar2.
If you are using OCCI and not OCI then take a look at MetaData::ATTR_DATA_TYPE and MetaData::ATTR_CHARSET_FORM which expose OCI_ATTR_DATA_TYPE and OCI_ATTR_CHARSET_FORM respectively.
Perhaps that will get you what you want.

How to determine the data content of the uploaded PDF from local

Hi,
I have a requirement wherein I will create a new program to upload PDF(contains contract information) from my local directory. Then base on the data in the PDF, I need to perform some contract validtion with SAP. The problem is, I do not know how to extract the data in the PDF. How to do so?
Thanks for your inputs.
Regards,
Marc

Hello Marc,
As we know in conventional ABAP when PDF file is read, SAP converts into binary format which is not directly readable. There are various applications which converts PDF to Text files, using these tools PDF file can be converted, uploaded and read the data.
SAP Portal technology gives reading PDF files option.

How to set the Background Color of a Text Field in a Tabular Report.

Hello,
I tried to set the Background Color of a Text Field in a Tabular Report.
But I was not able to change this colur.
In the report attributes --> column attributes
I tried already:
1. Column Formating -- >CSS Style (bgcolor: red)
2. Tabular Form Element --> Element Attributes (bgcolor: red)
but nothing worked.
Can anybody help me?
I Use Oracle Apex 2.2.1 on 10gR2
thank you in advance.
Oliver

in "Report Attributes" select the column to move to the "Column Attributes" page. In the "Element Attributes" field under the "Tabular Form Element" region enter
style="background-color:red;"
I will also check if there is a way to do this via the template and post here again
edit:
in your template definition, above the template, enter the following:
< STYLE TYPE="text/css" >
.class INPUT {background-color:red;}
< /STYLE >
(remove the spaces after the < and before the >)
change "class" to the class that the template is calling
(I'm using theme 9, the table has: class="t9GCCReportsStyle1" so I would enter t9GCCReportsStyle1)
A side-effect of using this second version is that ALL input types will have a red background color--checkboxes, input boxes, etc.

How to determine the transaction type?

Hello,
I have a requirement to disable the user when the role string field on the usr form is empty. I set up a post update entity adapter to do that and it works fine.
When I want to enable the user using the Enable button, the above post update entity adapter detects that the role string field is empty and the user is Active, it disables the user right back.
So, I need to set up a pre-update entity adapter that can detect the type of transaction. If the transaction is to Enable the Xellerate User, then I will update the role string to a dummy value (as long as it's not empty) so that the Disable adapter doesn't get fired.
Is this possible to do? Where can I find the transaction type information for a given Object?
Thanks
Khanh
