Copy Export entire schema csv spreadsheets

Oracle Database Tips by Donald BurlesonDecember 12, 2013

Question:  I need to export all of the tables in my schema into csv spreadsheet files.  I want a procedure that will create a csv file, copying every table in the schema into a comma delimited format.

Answer:  There is a way to export all table in a schema into csv files by using the script below.  This script has the benefit of allowing you to copy all Oracle tables in a schema into csv spreadsheet files, with the csv files having the same name as the tables.

The SQL*Plus code below will dump all tables into a csv file, and this code will export all tables in a schema into a csv spreadsheet format: 

-- This will create a csv spreadsheet file for all tables in this schema:

connect scott/tiger

set serveroutput on;

set lines 80
set head off
set colsep ','
set pages 0
set feed off

spool runme.sql

select 'set colsep '',''' from dual;
select 'set lines 9999' from dual;
select 'set head off' from dual;
select 'set pages 0' from dual;
select 'set feed off' from dual;

for table_rec in (select table_name from user_tables) loop

   dbms_output.put_line('spool '||table_rec.table_name||'.csv');
   dbms_output.put_line('select * from '||table_rec.table_name||';');

end loop;

select ' spool off' from dual;
spool off


The above code requires that you connect as the schema owner of the schema that you are using to create the spreadsheet files.  This will then select all of the rows from all of the tables in the schema and create a spreadsheet csv file for each table in the schema.
