Hi,

How do i get DDL of a Table from system catalog ?

Purpose :
1) i need to create an external table on the basis of  another table.
     create table ext_table (like table_name); ------------------> this doesnot work for external tables.
 
try - create table ext_table (like pg_catalog.table_name); - it worked for me.
 
 

2)  so i need to query catalog to get  definition of the table.
     on the basis of this definition i can create external table .
eg: i am looking for some thing like :

   select * from pg_catalog where table_name=' srikanth_ext_parallel_crt_sms_logs_child_depth_1_d_2008_03_30_daily ' ;

3) once i get the definition of the table , i need to use that definition for creation of external table in a script which will run in cron job daily for data loading.

Can anyone guide/help me in this ?
