30EA1: Determine column lengths before csv-Import

Hello out there,
I tried to import a csv (actually semicolon separated and enclosed in double quotes) into a new table using SQL Developer.
I got error messages that some columns are to short (ORA-12899). Now the question is, is there an option having SQL Developer determine the maximum length of the data to propose a suitable column width?
Wenn I convert the csv to Excel an import that, I get similar errors but much later in the process. So Excel-import seems to look much farther ahead than csv-import.
What I need is SQL Developer scanning the whole file to determine the maximum length of data an not only the first row or the first few 1000 rows.
Can this be achieved somehow?
Regards,
dhalek

Hi Dhalek,
Not sure if your problem is that we are not calculating the size of the columns correctly, we are not generating the inserts correctly or if we are not reading the rows with the columns that are large during the preview phase which is where we profile the data and determine the size of the columns. Can you see the rows that are rejected in the preview? When the table is created, are the sizes of the columns correct? Is it possible that your csv file is having the same problem with the single quote as the excel file? Once we have read the data, the generation is handled in the same way for both so the inserts should look the same.
Sqldeveloper uses java batch insert for the Insert method which is different from standard insert and inserting via a script. The rules are slightly different so rejections may differ. Also, failures reject the entire batch not just the bad row. For now, to limit the number of rejected rows, you can set the preferences->database->advanced-Sql Array Fetch Size to 1 for the import. This will generate only bad rows in the bad file and should make it easier to pinpoint the problem. You'll want to restore that value because it also affects any fetches done by SQLDeveloper. I'll need to research our generation of the single quote in the data.
Also you may want to try setting the preferences->database->load->preview characters limit to a very high number if you think the problem is that we are not reading the rows with the large columns during the preview. This is the overalll limit of characters that will be read from the file during the preview.
You can also try the insert script method to load your data which will eliminate any java batch insert issues.
Thanks,
Joyce

How to determine column length semantics through ANSI Dynamic SQL ?

I am looking for a way to determine the length semantics used for a column through ANSI Dynamic SQL.
I have a database with NLS_CHARACTERSET=AL32UTF8.
In this database I have the following table:
T1(C1 varchar2(10 char), C2 varchar2(40 byte))
When I describe this table in SQL*Plus, I get:
C1 VARCHAR2(10 CHAR)
C2 VARCHAR2(40)
In my Pro*C program (mode=ansi), I get the select statement on input, use PREPARE method to prepare it and then use the GET DESCRIPTOR method to obtain colum information for output:
GET DESCRIPTOR 'output_descriptor' VALUE :col_num
:name = NAME, :type = TYPE,
:length = LENGTH, :octet_length = OCTET_LENGTH
For both C1 and C2 I get the following:
:type=12
:length=40
:octet_length=40
So, even if I know that my database is AL32UTF8, there doesn't seem to be a way for me to determine whether char or byte length semantics were used in C1 and C2 column definitions.
Does anybody know how I can obtain this information through ANSI Dynamic SQL?
Note: the use of system views such as ALL_TAB_COLUMNS is not an option, since we wish to obtain this information even for columns in a complex select statements which may involve multiple tables.
Note: I believe OCI provides the information that we need through OCI_ATTR_DATA_SIZE (which is in bytes) and OCI_ATTR_CHAR_SIZE (which is in chars). However, switching to OCI is something we would like to avoid at this point.

Yes, I was wondering which forum would be the best for my question. I see similar questions in various forums, Call Interface, SQL and PL/SQL and Database - General. Unfortunately there is no Pro*C or Dynamic SQL forum which would be my first choice for posting this question.
Anyway I now posted the same question (same subject) in the Call Interface forum, so hopefully I'll get some answers there.
Thank you for the suggestion.

SQL Developer - mapping column names for csv import

In Apex I can do a spreadsheet upload to an existing table and it asks me to map source data to existing table, and it usually has the columns correct. I don't know if it imports them in order or what(first column name in table maps to first column in csv file, etc). SQL Developer makes me choose the mappings myself - it doesn't attempt to do a mapping at all, and some of my fieldnames are exactly the same. Am I missing something? Is there a way to get SQL Developer to try to do the mapping for me?
Note: in apex and sql dev, you should use csv only... they let you choose xls, but xls fails in both products every time.

So I guess SQL developer can't do this?

How do I determine the length of a column?

Does anyone know how to determine the length of an Oracle column through sql statements? I know in SQL Server you can use the COL_LENGTH function to find the maximum length for a particular column, but I haven't been able to find an equivalent for Oracle.
We have a column in a database that is a VARCHAR2 and can be any szie from 64 to 255 characters. I need to determine on the fly from a running client application what size the column is in the current database.
Thank you very much for any help you can give me.

select data_length from user_tab_columns
where table_name='YOUR_TABLE' and column_name='YOUR_COLUMN';
if you want function to return this value, create function like below..
create or replace function col_len(t varchar2,c varchar2)
return number is
n number;
begin
select data_length into n from user_tab_columns
where table_name=upper(t) and column_name=upper(c);
return n;
exception
when others then
return 0;
end;

Increase the column lengths of excel sheet through abap

I developed a abap program and it was displayed the output.
So i need to display this out put in excel sheet.
for that I read the out put and placed in the excel,
the only problem is the column lengths are small
after download i am dragging the each column,
But i need to increase the each column by the program
   How can I ?
I am using the following code
      lastline = new_line_c + 13.
      DO .
        READ LINE sy-index LINE VALUE INTO it_read-excel.
        APPEND it_read.
        IF sy-index > lastline.
          EXIT.
        ENDIF.
      ENDDO.
      lastline = new_line_c - 38.
      colm = ( length - 37 ) / 18.
      colm = colm + 4.

Hello Ravi,
Thank you very much for your suggestions.. but still have some more doubts:
What i want to do is :
-->call report in background job with a selection criteria.
-->the output of the report should be trasnsfered to excel sheet
-->then the excel sheet should be sent to XI..
My doubts are:
-> is it possible with every report or we need some extra code to achieve this
-> If yes, then how exactly it should be done. can you please explain in more detail.
Thank you very much for your help.

How to determine the length of a LRAW field

Hi
I'm trying to write a generic persistency class that saves data in a table with a lraw field.
As required the lraw field must be preceded by a length field of type INT2, but how can I calculate the actual length of the lraw field?
kind regards Thomas

Hi Martin
I'm sorry to tell you that you are wrong. The INT2 field must contain the actual length.
I have a table with a LRAW of 1024 bytes, but if I put 15 to the length field, then only 15 bytes are stored in the database.
Of course I could just enter 1024 for the length, but that would wast a lot of database space - and performance.
My class has a persistency method that inserts or updates a record in the database. The data that should be stored in the LRAW is sent to the method via a pointer (field symbol) of type X. This pointer can point at any data type.
Something like this:
field-symbols: <input> type x.
field-symbols: <lraw> type x.
*assign any field to <input>
assign <lraw> to mydbtable-lraw_field casting.
<lraw> = <input>.
*here i need to determine the length of mydbtable-lraw_field before i store the content to the database.
By debugging I can tell that if the pointer points to a char 32 field then the length of the X pointer is 64 and if the pointer points to a timestamp then the length of the x pointer is 8, but how can I determine this length programmatically - either from the x pointer or from the LRAW?
Best regards
Thomas

How to define cells/columns for export/re-import to another app

I want to export a basic contact list to then import into another program (it's an email program, doesn't matter). It's a basic table with 3 columns: first name, last name, email address. How do you define the columns/cells so when importing in another app it knows what is what. Want to export as a tab-delimited or comma-delimited text file.
thx.

Christopher,
It's hard to say what that un-named other app might require for field identification, but your best bet is to have the field titles in a Header Row.
To produce a comma-delimited text file, assure that your data table is the only thing in your document. Isolating the data in this way will prevent complications. Then, File > Export > CSV.
To produce a tab-delimited text file, Select and Edit > Copy the table in Numbers and then Edit > Paste and Match Style in a Pages doc. Save the Pages doc.
Regards,
Jerry

Export failure due to column length in DRM 11.1.2.1

Hi All,
We have migrated recently from 11.1.1.43 to 11.1.2.1 and the issue is with one of the exports
In the earlier version you have the option of manipulating the column length inspite of the actual length set in the table column. This can be edited in the column options when the table is selected at the last option of export.
Now the issue is i could see the length of the column in the 11.1.2.1 export option but i was unable to edit that length and reduce it to the required
Viz., i have the column length of 80 set in the table and in the export it is restricted to 50 in the old version. Now i'm unable to edit this in 11.1.2.1
Could anyone help me on this? I believe i may be missing some basics here
Thanks

In the earlier versions by default every property length is treated as 50 Characters while we export the data from DRM,
Now in the new version we need to alter the table before we export based on the property length,
Thanks,
Murali

How to adjust column length in function REUSE_ALV_GRID_DISPLAY

Hi,
I am using this function REUSE_ALV_GRID_DISPLAY to display .Please tell how to adjust the column length in this function, so that it is set to default field name size.
thanks

Hi anu,
The column width can be adjusted by using the following method:

Weird csv import behaviour...

Hi guys!
I was wondering if any of you encountered a werid csv import behaviour:
If the csv file I'd like to import has columns shortened...I mean sometimes you have to click twice on a column to see its full content..and I'm talking about the situation where you don't see it in a full spectrum. Then if im trying to import it I receive an error...if immediately after that I click twice on every column of that csv file...the import works fine...
Any ideas?
With regards,
PsmakR

Re: [iPlanet-JATO] Finding the database column length

This is the technique I would recommend. If you'd like to wrap this
mechanism up in the model class itself, create a subclass of QueryModelBase
that provides such a method and use that as the base class for all your
QueryModels.

Chidu,
The result set that you get back is a JDBC ResultSet, not a "JATO" resultset. In ND, everything was wrapped in a "spider" data
structure, and therefore, difficult to get to the underlying datastructure, in many cases. In some case ND made it easier to do
certain things, and in other ways, made it more difficult or impossible(like seeing the SQL for an insert, update, delete).

Anyway, looking at the java.sql package, you can do this.
java.sql.ResultSet rs = <jata-model>.getResultSet();
java.sql.ResultSetMetaData rsMeta = rs.getMetaData();
// not sure if this is what you need, but it was the closest thing I couldfind
int colSize = rsMeta.getColumnDisplaySize(int column);
There are numerous other methods in the ResultSetMetaData interface thatmay be of use as well.

Need help in modifying the column length

Hi Experts,
I need to modify the length of a column from char(10) to char(5), but it's showing the error of:
ALTER TABLE appr_group_table MODIFY (APPR_TBLNO CHAR(5)) It's showing the below error:
ERROR at line 1:
ORA-01441: cannot decrease column length because some value is too bigI've checked in the dbase but there is no any value of this column having more than 5 characters:
SQL> SELECT APPR_TBLNO FROM appr_group_table;
APPR_TBLNO
ANTAB
ANTAB
ANTST
SCCTR
SOTAB
SOTAB
SOTAB
SOTAB
SOTAB
SOTAB
SOTAB
11 rows selected.Thnx in advance for helping me out.....

char means fixed length variable. when you say char(10) oracle will reserve 10 places for your data. that means in your output what you are seeing as blank spaces are also considered as data. that is the reason, it is not allowing you to reduce the size.
better solution is to create new column with varchar2 or char(5) datatype and transfer this column data into new column and then drop original column.

Set the column length in an sql query

Hi,
Is there a way to set the column length in a query without using sqlplus commands like row size and format column.
I'd like to do it just from the sql query itself.
select 'this is a test' from dual; Can I define the width of this column in the select statement
Cheers.

Use RPAD,
SQL> WITH T
2       AS (SELECT 'this is test' str FROM DUAL
3           UNION ALL
4           SELECT 'this is a long test' FROM DUAL
5           UNION ALL
6           SELECT 'this is a long long long long test' FROM DUAL)
7 SELECT RPAD ( str, 20) str,LENGTH( RPAD ( str, 20)) len
8    FROM T;
STR                         LEN
this is test                 20
this is a long test          20
this is a long long          20
