[SQL] Calling a table in another database from plpgsql

[deepthi]

Hi,

I have function called test1() in database 1. I need to input the value from
this function into another table which is in database2.

How can i achieve this task in plpgsql. I went through some documentation and
found out that it is possible through dblink.

I infact downloaded the dblink package in contrib folder. But still when i tried
to use dblink in the following manner:

SELECT * from dblink('host=192.168.0.50 dbname=AK1 user=akteam','Select userid
from user_reg') as t (userid integer);

I am getting an error as "ERROR:  function dblink("unknown", "unknown") does not
exist"

Is dblink the only way of connecting the databases and if so what is the exact
step by step procedure to be follwed to download dblink and use it to connect
databases.

Thanks in advance,
Regards,
deepthi

Hi,

I have a database which has been set to encoding UTF-8.

I have a table in this database in which i store the details of all the
registered users. I am using PL/PGSQL and using one function i am entering the
values into the database. There is one column for entering the passwords of all
registered users. I want to store these passwords in an encrypted manner in the
table. Can i encrypt the password in the stored procedure and will i not loose
any data by entering the passwords in an encrytped manner.

Thanks in advance,

Regards,
