Adding column names to data file

Hi,
I have a question regarding writing to file. Currently in my program, when I start running it, a dialog box pops up and the user gets to pick/ create a file. My data is written on to a file as columns. I want to add column names to the file. Any suggestions on how to do it? Since the file is created by the user at run time and since the column names have to be added just once at the beginning, I'm not sure how to go about doing this. Any suggestions or pointers?
Thanks,
Sukanya

Write to measurement file, adding column name in text file.

Hello,
Is it possible to add own column name for a text file using Write to measurement file function?
In the created file I have three different columns (I want to name them Time/Voltage/Date&Time).
Maby I should choose different write option like write to spreadsheet?

You are going to have to post some actual code if you want us to help here. Otherwise it is a complete shot in the dark. Posting an example CSV file of what you have and what you want would also be beneficial.

Reading MS Project column names and data on the fly from a selected View

Hi guys,
I have several views on my project file (MSPROJECT 2010) and I want to build a macro so that;
1. User can select any view ( Views can have diffrent columns and the user may add new columns as well)
2. User runs the Macro and all the coulmns along with the tasks displayed in the view will be written to a excel file. ( I don't want to build several macro's for each view, I'm thinking of a common method which would work for any selected view)
The problem I'm facing is that how will i read the column names and data for a particular view on the fly without hard coding them inside the vba code ?
The solution needs to work on a master schedule as well.
Appreciate your feedback.

Just to get you started the following code writes the field name and data for the active task to the Immediate window.
Sub CopyData()
Dim fld As TableField
For Each fld In ActiveProject.TaskTables(ActiveProject.CurrentTable).TableFields
If fld.Field >= 0 Then
Debug.Print Application.FieldConstantToFieldName(fld.Field), ActiveCell.Task.GetField(fld.Field)
End If
Next fld
End Sub

How can i get the column names in CSV file.

Hi,
After execution of infospoke i can not see the column names in that file.How can i get column of respective infoprovider?
Thanks,
Gananadha Lenka

Hello Gana,
Actually while exporting the data using Info Spoke, we have the possibility to modify the data that we send. This is possible using transformations.
In your Info Spoke, you have a tab called Transformations.
Here you need to create an implementation and then use BADi to populate data.
Check if you can write a start routine sort of thing here and insert a new record into the internal table by hardcoding with your field headings.
Let me know if you dont know how to create transformations.

How to list column names and data types for a given table using SQL

I remember that it is possible to use a select statement to list the column names and data types of databaase tables but forgot how its done. Please help.

You can select what you need from DBA_TAB_COLUMNS (or ALL_TAB_COLUMNS or USER_TAB_COLUMNS).

Bulk Load data without specifying column names in control file

I am totally new to the world of Oracle databases and am having some trouble doing some basic data imports from a csv file. I have a large amount of data in an excel spreadsheet (a couple hundred columns by varying numbers of rows from 2- several thousand) which I want to import into my Oracle 11g Database. Currently I am trying to use sql loader and specify the import syntax in the control file. From the examples I've seen so far, it seems you must specify the columns individually for what you are importing. This is simply not reasonable for several hundred columns of data.
Is there sql loader syntax (or a better method all together) to import a comma delimited csv or excel spreadsheet into an oracle database where it automatically generates a table and columns based on the data in the target import file? Even if I must first create the table in the database, my key issue is being able to generate the column names during import to match the column headers in the import file. I appreciate any help you could provide.
FYI here is my first meager attempt at importing a comma delimited csv, here is my ctl file:
load data
infile 'C:\filepath\mock_data.csv'
into table allData
fields terminated by "," optionally enclosed by '"'
It says Syntax error at line 4. Expecting "(", found end of file.
I suspect there is more at issue here than a missing "("

You have to create the control file to map to the table.
Since you would already have created the tables, you could generate the controlfiles based on the table structures.
See the "unloader.zip" file under the Files link at http://asktom.oracle.com
-- it has scripts to create unload a table to a flat file and to create the SQLLoader controlfile to reload that data to another target database. It would be the second set of scripts that you can use.

Use of PL/SQL to populate table columns from XML data file

I'm trying to find the easiest way to transfer data from a flat file that is in XML format into a traditional Oracle table. Not retaining the XML but actually map an XML element to a column so standard SQL, Forms, Reports, etc can access like it was created using a Form.
Example: Table A has column names Tom, Dick and Harry and the XML file has elements Tom, Dick and Harry and I just want a function that maps and inserts/loads the data into Table As individual columns.
The process needs to be easily initiated by an end user. The user gets the XML data file via an email attachment and needs to do something like a Concurrent Request to pull in the file and load it. Using PL/SQL would be great.
I appreciate any help that can be provided.

Hi,
HELP!!!!!
We are having the same problem and we are using oracle 10ir2.
We create an object type (sql type globally not in a package):
CREATE OR REPLACE TYPE G_EX AS OBJECT
( EX_ID NUMBER ,
EX_CON VARCHAR2 ( 100 ) ,
EX_L VARCHAR2 ( 30 ) ,
EX_T VARCHAR2 ( 4000 ) );
CREATE OR REPLACE TYPE G_EX LIST AS TABLE OF GEX AS ;
then we insert data through a bulk collect within the package with the table declared of this array of object types:
v_table G_EX _LIST:= NULL;
SELECT G_EX (ex_id
,ex_con
,ex_l
,ex_t )
BULK COLLECT INTO v_table
FROM exs_lookup;
I am using the syntax (below) but it gives PL/SQL: ORA-00902: invalid datatype
sometimes not always:
SELECT G_EX ( ex_id
,ex_con
,ex_l
,ex_t )
BULK INTO v_data_record
FROM TABLE (v_table)
WHERE ex_id = p_key;
where p_key - is a number type
and v_data_record is a G_EX object type.
I was wondering if anyone else encountered a similar problem, and knows what we may have done wrong. Since we dont understand why this piece of code is throwing this ora-00902 errors occasionally not always.
Also, if we restart the database up once this errors occurs it appears to stop throwing this ora_00902 error for a lenght of time. Then it comes up with the ora-00902 error again (why?)
thanks

Dynamic Column Names in Flat File Destination

Hello,
Inside a Data Flow Task, I have an ADO.Net data source which executes a stored procedure that provides results in 5 columns.
The requirement is to have it connect to a flat file destination, such that the column names is dependent on what data was pulled by the data source. There is a variable indicator which identifies the data that was pulled. For example:
If the indicator is 0, then the columns names will be A,B,C,D,E. Otherwise, if the indicator is 1, then column names will be V,W,X,Y,Z.
Any suggestions will be of great help.
AJ

If you only have two variations then use a branched execution (based on precedence constraints) and direct it to one DFT or another based on the result returned by the stored procedure.
Otherwise use .net
code to create one package or another dynamically.
PS: I suggest not to bother using SSIS for such a simplistic scenario.

In the feed file it should be null. but the alias column is populted with empid
Can you please let me know what is wrong here?

Multiple columns in a data file, but accounts not periods

Hi there,
A very quick question.
If I have a data file with, for example AcctDetail down the side and accounts across the top, am I right in thinking I can't load like this? Is it only periods that can be in multiple columns?
I'm trying to adapt an existing file, without changing it too much, but I think this might be beyond BPC!
Thanks,
Jason

Hi there,
The data I'm loading is actually Intercompany data for one unit, for one period.
So I have my affiliate (or counterparty, whatever term you use) down the rows, and the designated intercompany accounts across the top.
I don't need multiple columns for periods, as I'm only loading one period, but I would prefer to use multiple columns for Accounts dimension instead.
I know I can nest affiliates and accounts in the rows, but as I mentioned I would rather avoid changing the data file as much as possible.
Hope that make sense!
Thanks,
Jason

SQL*Loader . A column value in data file contains comma(,)

Hi Friends,
I am getting an issue while loading a csv file to database.
A column in datafile contains a comma .. how to load such data?
For ex, a record in data file is :
453,1,452,N,5/18/2006,1,"FOREIGN, NON US$ CORPORATE",,,310
Here "FOREIGN, NON US$ CORPORATE" is a column and contains a , in the value.
I have specified optionally enclosed with " also.. but still not working
Here is my control file:
options (errors=100)
load data
infile 'TAX_LOT_DIM_1.csv'
badfile 'TAX_LOT_DIM_1.bad'
replace
into table TAX_LOT_DIM
fields terminated by ',' optionally enclosed by '"'
trailing nullcols
TAX_LOT_DIM_ID ,
TAX_LOT_NBR ,
TAX_LOT_ODS_ID ,
RESTRICTION_IND ,
LAST_UPDATE_DTM ,
TRAN_LOT_NBR integer,
MGR_GRP_CD optionally enclosed by '"' ,
RESTRICTION_AMT "TO_NUMBER(:RESTRICTION_AMT,'99999999999999999999.999999999999')" ,
RESTRICTION_INFO ,
SRC_MGR_GRP_CD
Problem is with MGR_GRP_CD column in ctrl file.
Please reply asap.
Regards,
Kishore

Thanks for the response.
Actually my ctrl file is like this with some conversion functions:
replace
into table TAX_LOT_DIM
fields terminated by ',' optionally enclosed by '"'
trailing nullcols
TAX_LOT_DIM_ID "TO_NUMBER(:TAX_LOT_DIM_ID ,'999999999999999.99999999')",
TAX_LOT_NBR ,
TAX_LOT_ODS_ID "to_number(:TAX_LOT_ODS_ID ,'999999999999999.999999')",
RESTRICTION_IND ,
LAST_UPDATE_DTM "to_date(:LAST_UPDATE_DTM ,'mm/dd/yyyy')",
TRAN_LOT_NBR integer, --"TO_NUMBER(:TRAN_LOT_NBR,'999999999999999.99999999999999999')",
MGR_GRP_CD char optionally enclosed by '"' ,
RESTRICTION_AMT "TO_NUMBER(:RESTRICTION_AMT,'99999999999999999999.999999999999')" ,
RESTRICTION_INFO ,
SRC_MGR_GRP_CD
For char columns , even i dont give any datatype, i think it will work.
And pblm is not with this hopefully.
