Spool an output file to dynamic filename

Hi.
Let say I have an Oracle Script as following:
spool c:\hms_report\HMS.xls
SELECT
field1||chr(9)||field2
from table1;
spool off
exit
Question:
Currently the output file will be HMS.xls
If I run the script thrice a day, the HMS.xls will be overwrite.
Is there any way to name the output file to be HMS+sysdate ie: If I run the script on 05-Nov-2002 09:00,
the output file name will be HMS051120020900.xls
where 05 = dd
11 = mm
2002 = yyyy
0900 = hhmi
Thanks.

Have you actually tried what you proposed below? I think not. And I don't see that working. Still, if you do succed like
you have proposed, please tell me.This works, see this SQL*Plus session:
SQL> column file_name new_value fname noprint
SQL> select 'HMS'||TO_CHAR(SYSDATE, 'DDMONYYYYHH24MI')||'.xls' file_name from dual ;
1 row selected.
SQL> prompt &&fname
HMS05NOV20020908.xls
SQL> spool &&fname
SQL> select sysdate from dual ;
SYSDATE
05-NOV-2002
1 row selected.
SQL> spool off
SQL> exit

Adobe PDF printer - saves output file as filetype+filename need it to save only as filename

I am using windows xp pro, when i create the pdf file with adobe PDF printer it creates the file name "Ami Pro - filename.pdf" I really need it to create the file name as "filename.pdf". Can you please help me - thank you

Thank you Bernd - Explorer will let us change the file name one at a time, however I am creating numerous pdfs at a time, and its a pain to correct them one at a time, or to create a bat file to do this. Does anyone know if the Adobe PDF printer has a feature that will eliminate the file type? thanks

Sender File Adapter - Dynamic Filename?

Dear All,
I have a simple requirement to retrieve a file named "XXX_ddmmyy" from an FTP site. The FTP site administrator will place a new file everyday. The date is part of the filename.
I can find a lot of information on how to set the Filename for a "Receiver File Adapter", but none about dynamically setting of the filename for a "Sender File Adapter".
Can you help please?
Kind Regards
Farshad

Hi,
You have mentioned over here that the requirement is to get the file "XXX_ddmmyy" from an FTP site.
Is that site strictly for keeping files related to your requirement only or lot of other files are also being placed???
If its strictly related to your requirement then you can use the filename "*.extension" and set the processing mode as "delete" so that once the File Adapter picks the file it will be automatically deleted.
But here disadvantage is that the file wont be no longer present in FTP site once it is picked by File adapter.
Thanks,
Lekshmi.

Export query results to flat file with dynamic filename

Hi
Can anybody can point me how to dynamic export query serults set to for example txt file using process flows in OWB.
Let say I have simple select query
select * from table1 where daterange >= sysdate -1 and daterange < sysdate
so query results will be different every day because daterange will be different. Also I would like to name txt file dynamicly as well
eg. results_20090601.txt, results_20090602.txt, results_20090603.txt
I cant see any activity in process editor to enter custom sql statment, like it is in MSSQL 2000 or 2005
thanks in advance

You can call existing procedures from a process flow the procedure can create the filename with whatever name you desire. OWB maps with file as target can also create a file with a dynamic name defined by an expression (see here ).
Cheers

Sri,
You have specified payload:input,1..... in ur variable substitution configuration. Is "input" the name of ur Message Type object in repository. If not, specify the name of the Message Type referred to in ur inbound interface.
We tried this option and generated an additional field in the XML data given as input to the file receiver adapter, to be used for substitution purpose only. We avoided specifying this field in our content conversion , however it still gets written to the file!! if u able to crack it let us know

Stored procedure : spool to output file

i have to spool data from a stored proc to a csv file.I am using dbms_output.put command as i have mulitiple things to put in a row , comma delimited
My proc looks like this
create or replace proc xyz
declare
cursor c is select x y z .....
form
d f f f
where ....
variable declaration
begin
someting something ..
for rec in cursor
loop
dbms_output.put(x1||',');
dbms_output.put(x2||',');
dbms_output.put(x3||',');
dbms_output.put(x4||',');
dbms_output.NEW_LINE;
endloop
This does not seem to be working ,Can you please tell me the correct way to do so .
I need a comma delimited file at the end .

I cannot use util_file .
I am ussing dbms_output.put . Thats fine .
i am spooling currently
I want to know how I can set the SET variables that only the dbms_output.put variables are spooled to the .
When you do spool get all the command s?.
Currently i am doing this
$ORACLE_HOME/bin/sqlplus -s <<EOI
$CONNECT_STR
WHENEVER SQLERROR EXIT FAILURE;
SET FEED OFF TERM OFF
SET SERVEROUTPUT ON
SPOOL $SQL_LOG
BEGIN
${PROCESS_SCHEMA_NM}.${STORED_PROC}.CONVERT_FLEX_2_TIMESHEET;
END;
is this correct ?

Making a script that generates an output file dynamic

I've created the following script to run it from within SQL*Plus on my PC to generate a report regarding specific details about all my databases in one file. The idea is to get 1 result of all my databases.
Spool C:\output.txt;
-- start DB1
CONNECT system/pass@DB1;
COLUMN host_name format A18;
select * from v$database;
set line 380;
set pagesize 50;
select * from v$session order by username;
DISCONNECT;
-- end DB1
-- start DB2
CONNECT system/pass@DB2;
.......................same code as for DB1..................................
DISCONNECT;
-- end DB2
-- start DB3
CONNECT system/pass@DB3;
.......................same code as for DB1..................................
DISCONNECT;
-- end DB3
Spool off;
The above script, for instance, generates the name of the database and the sessions details of all my databases.
I have 40 DBs and they all have the same password for user system.
My question, is there a way to re-write this script to achieve the same thing but in a dynamic way. ie: the database connection string becomes dynamic, so that I write the code only once and if the code changes, I change it only one time instead of 40 times.
Notes: I'd like to run the script from SQL*Plus on my Window PC, I know that the same thing can be achieved by running a script on the DB server by using /etc/oratab, but actually these 40 DBs are on 10 different DB servers and there is no oratab used.
Many thanks for any tips,
Thomas

By awk on unix, or gawk or mawk on Windows (download http://www.klabaster.com/freeware.htm or ftp://garbo.uwasa.fi/pc/unix/gawk2156.zip) it's a easy task.
File select.sql (your query which you want run)
spool E:\Scripts\Sql\&1..log
select table_name from user_tables;
spool off

You have an alternative with mawk which seems more fast, command are same, just replace gawk by mawk.

Using Spool to output data to file

I am trying to write some sql scripts to do spooling of data to files automatically on the 1st day of each month. I use the spool command to output to text file but have problems setting the filename to tag with the date stamp.
Script 1 : to get current year and month and then call script 2 to output to file
==================================================================================
set linesize 800
set pagesize 999
set heading off
Remark Get current year and month from database
Remark
variable v_yyyymm number;
declare
begin
Select to_number(to_char(to_date(to_char(sysdate,'DD/MM/YYYY'))-1,'YYYYMM')) INTO :v_yyyymm From dual;
end;
print v_yyyymm
@script2.sql :v_yyyymm
exit
script2.sql : spool to file
============================
spool Monthly\Audit_Trail_&1..txt
SELECT * FROM AUDIT_TRAIL WHERE TO_NUMBER(TO_CHAR(DATESTAMP,'YYYYMM')) = &1;
spool off
Upon execution in Windows environment, it says that unable to create spool file. It seem
that i can't use a bind variable in the Spool Command. Any alternative ways of achieving that ??? I need the file name to be taged with the date stamp ?

Yet another example:
I usually create a ".cmd" file to run a sql script such as the following:
spool j:\DailyMetrics.sql
select 'spool j:\Daily_Metrics_'||to_char(sysdate,'mmddyy')||'.txt' from dual;
select '@j:\DAILY_METRICS;' from dual;
select 'spool off' from dual;
spool off
This, of course, allows me to then run the "j:\DailyMetrics.sql" script which now spools to a file with today's date as part of its filename and calls the reporting script to generate the data, and then spools off.
Obviously, you can put everything in the ".cmd" file and just schedule it to be run each day.
Good luck :)

Spooling queries output to text file

Hi All,
I need help to spool the output to a text file for a sequence of queries that I need to execute.
Lets say, the queries would in a sql file as follows:
Select * from emp where empId = 1
Select * from emp where empId = 2
Select * from emp where empId = 3
The output in txt file should have the details as
Employee Id Employee Name Employee Designation
1 Alex Manager
2 Conrad Sr Manager
3 Herman Technical architect.
I am trying to execute this from sql developer.
Any pointers in this regard would be highly helpful.

Hi,
Welcome to the forum!
Why not use just one query
SELECT       *
FROM       enp
WHERE       empid     IN (1, 2, 3)
ORDER BY empid
You can use "SPOOL filename APPEND" to re-open and add to an existing spool file after it has been closed, but there's no need to in this case.

Dynamic file name in case of .txt output files

Hi all,
I have a query related to dynamic file name scenario.
In case of IDOC-XI-FILE sceanrio,
Is it possible to generate .txt file name based on Plant number like
%<Plantname>%_%<BusinessDay>_filename.txt
Note:I have implemneted this for .xml output files but I am not able to implement it for .txt output files .
PLEASE HELP ME .
Regards
Prabhat

Hi Prabhat,
I think, the normal Dynamic File Name generation should work fine in your case also. Even if you perform Content Conversion, you can use Variable Name Substiution to create your Destination file name as, the name of the file is determined first and only then is the content converison perfromed.
for info on content conversion, I would suggest that you go through this thread and check my reply,

Setting up FileName for Output file in SendPort

Hi - I have a requirement setting up FileName in output file. For instance say, whatever I receive in the 'FathersName' field that Output File should be with that File Name.
For e.g. if data received in FathersName field is JOHN, output file name should be JOHN.xml
I am using File Adapters on Receive and send side.
Can this be achieved just by Messaging Scenario or do I need to implement this using Orchestration ?
If so, please advise on how to do this ?
e.
MBH

To achieve this, you will have to set your filename value on one of the Context Properties available as a File Adapter macro. For example FILE.ReceivedFileName is mapped to the %SourceFileName% macro.
You have several options to do this:
Set FILE.ReceivedFileName in an Orchestration. It does not have to be Promoted.
Write the Property ReceivedFileName in namespace
http://schemas.microsoft.com/BizTalk/2003/file-properties in a Custom Pipeline Component.
If FathersName can be used in the file name unmodified, you set FathersName as a Promoted Property on the schema and Promote directly to FILE.ReceivedFileName.
For 1 & 2, you will have to extract FathersName somehow, such as a distinguished field.
A Custom Pipeline Component or direct Promotion are the only way to achieve this in Messaging only.

When I run this script nothing is output to the screen or spooled to a file

When I run this script nothing is output to the screen or spooled to a file. What do I need to do to get output from this script.
SET SERVEROUTPUT ON size 100000
DECLARE
v_schema     Varchar2(50);
v_statement      Varchar2(500);
v_name varchar2(30);
v_id varchar2(8);
v_pwd varchar2(16);
v_acct varchar2(16);
CURSOR get_schemas IS
SELECT DISTINCT owner
FROM all_tables
WHERE table_name = 'USERID'
ORDER BY owner;
BEGIN
OPEN get_schemas;
LOOP
FETCH get_schemas INTO v_schema;
EXIT WHEN get_schemas%NOTFOUND;
          v_statement := 'SELECT name,usid,passwd,acctnum INTO v_name,v_id,v_pwd,v_acct FROM '||v_schema||'.userid';
          execute immediate v_statement;
          DBMS_OUTPUT.PUT_LINE('Name='||v_name||' ID='||v_id||' PW='||v_pwd||' AC='||v_acct);
END LOOP;
CLOSE get_schemas;
END;
/

Do I include several variables after the INTO or just
one?
How do I loop through the record and print the
individual variables?
I appreciate your assistance!He already gave you the answer above:
v_statement := 'SELECT name,usid,passwd,acctnum FROM ' || v_schema ||
'.userid';
execute immediate v_statement
INTO v_name, v_id, v_pwd, v_acct;
If this is not printing any output, it is because you don't have a table named USERID... what are you trying to do?

Hello, How do I tell sql+ to spool output file from windows to Unix server?

Hello, How do I tell sql+ to spool output file from windows to Unix server?
I am new to SQL+ and just learned how to spool the file. But file is saved in my local windows enviroment and since it's 2GB in size...I want to spool it directly to another remote unix server.
Pls answer in detail... I have been to most of the thread and didn't see relevant answer to above question.
Am I suppose to develope some script which FTP the spool file directly to the server I want to
or
i Have to use UTL_FILE Package ?
Thanks for reply

You may not be able to...
SQL*Plus can only spool to the local machine. If you have mapped a directory on the Unix server from your Windows machine, you can specify that directory in your SPOOL command.
You could telnet to the Unix server, run SQL*Plus there, and spool the file to a local (Unix) directory.
If the Unix server is also the Oracle database server, you could use the UTL_FILE package rather than using SQL*Plus to spool a file.
If the Unix server is also an FTP server, you could also FTP the file from your local machine to the server.
Of course, I would tend to re-examine a requirement to regularly generate a 2 GB text file. It seems likely that there is a better way...

added {noformat}{noformat} tags so the issue can actually be seen

In your SQL, concatenate the columns.
for e.g
select object_id||object_name||owner
from all_objects
You'll always get a space between columns if you spool the output from sqlplus as the defualt column separator is a space. Also, it is generally best to have the columns delimited by a pre-defined character, so that any program that reads the file will know the start and end of a field or column.
If you do want a fixed-length format file, you can use functions like LPAD or RPAD.
e.g.
select RPAD(object_id,10,'0')||RPAD(object_name,20,'N')||RPAD(owner,30,'N')
from all_objects
