Empty Table

From
Date:
Hi list,

I have many tables with many constraints and I would like to empty all my 
tables.

There is any simple way to do it ?

I have pgAdmin here but not psql.

Any help would be glad.

Regards
Ezequias

if you have too many tables , generate the above commands
by using a query on tables information schema table.
hope it helps.

Thank you all for a so fast reply.

I did a backup PLAIN with pgAdmin and I had to delete the information of the 
current database (the database I used to make the backup).

I think that's why pgAdmin does not work with plain backups on Restore.

What does occurs with the information schema when I restore from one database 
with a name to other with another name ?

I dont think i clearly understand your requirement.

Are you wanting to restore the "PLAIN" backup of a database
with a different database name ?

what do you mean "deleting information of current database ..."

I have not used pgAdmin as i prefer cmd line mostly.

eager to help,  (expect my next reply aft 6 hrs , i am abt to crash now).
hope someone else helps u in meantime.
