What Is the Quickest Way to Export a Table to a Flat File?
Answer:
The quickest way to export a table to a flat file is probably to use the SQL*Plus SPOOL command. It allows you to record SELECT query result to a text file on the operating system. The following tutorial exercise shows you how control the output format, start the spooler, and dump all record from a table to a flat text file:
>mkdir oraclexe est
>sqlplus /nolog
SQL> connect HR/globalguideline
SQL> SET HEADING OFF;
SQL> SET FEEDBACK OFF;
SQL> SET LINESIZE 1000;
SQL> SPOOL oraclexe estemployees.txt;
SQL> SELECT * FROM EMPLOYEES;
......
SQL> SPOOL OFF;
You should get all records in employees.txt with fixed length fields.
