I have to query 500 tables in my database and spool the tables into 500 separate csv files.
I can do it by one by one. But I am looking for a block which can perform the task without manually entries. Another challenge is that I need each table in one csv file. This means I have to create 500 csv files containing data for 500 tables ...one for each table....
Can anybody suggest or give a sample template would be really helpful..
Awaiting your kind reply frndz...
Anand

HI Michel,
Thanks for your reply...
I can do it by basic SQL commands.
Set colsep ','
set heading on
set feedback off
set flush off
set termout off
set echo off
Spool c:\\anu\temp7.csv
select * from CDFTS.table1;
Spool off
but I am looking to have a block which take up table names from all_tables and save the dump in individual csv files..
I hope I am clear.
Please let me know if u need any furhter info.

Yes Michel,
I would need to save the dump files of each table in a seperate csv file. Since I have more tables, I am looking for a query to take up the table names from all_tables.....
If passing the table names makes the code complex. I will pass the table names all at once ( if i can) but Please let me know the code to save the table content in seperate csv files.
Please dont hesitate if I am not clear

Hi Swan,
Thanks for notifiying that.
I wil be sending these csv files for auditing purpose. They wil not be validating at data level. However, they are extremely interested to have the table content in seperate CSV files.
Regards,
Anand

Thanks Michel,
It's an elegant answer. With this sql I have almost acheived my objective.
select '
Set colsep '',''
set heading on
set feedback off
set flush off
set termout off
set echo off
Spool c:\anu\'||table_name||'.csv
select * from CDFTS.'||table_name||';'||'
Spool off '
from all_tables
/
Above query given by you has absolutely served my purpose.
This query is generating the sql commands which needs to be executed. I would need to copy the output and then needs to run in the SQL prompt.
Is it possible to include the generation and execution in single step

Excellent Michel,
I am extremely delighted with the answer.
I can see seperate csv files for each Table. Here for empty tables The csv file was created empty. For these kind of tables I want to display the column names without data.
I tried by changing different set operators but not sure which one meets my requirement.
Kindly share if u have any suggestion.
Thank you...
Query I have used.
set heading off
set feedback off
set flush off
set termout off
set echo off
spool c:\anu\query.sql
select '
Set colsep '',''
set heading on
set feedback off
set flush off
set termout off
set echo off
Spool c:\anu\'||table_name||'.csv
select * from CDFTS.'||table_name||';'||'
Spool off '
from all_tables where owner='CDFTS'
/
spool off
@c:\anu\query.sql

Hi Joy,
Iam doing this exercise for bulk of tables.
I want to have all column names in a row as how it appears if data exists.....though there is no data.....
At the end if it displays " no rows returned" then it would be perfect.
Thanks,
Anand

Thans Swan,
I understand that extracted CSV file will fail to represent the Database data at below instances.
1. if the table datacontent has a comma in it. it will be drifted to next cell. thus the whole row fails to represent the right columns.
2. Some times SQL plus may truncate the data on display.
3. csv file convers datatypes to string format.
Swan ,Please add up if any more instances present in such way.
Thanks
